Race walking shares many fitness benefits with running, research shows, while most likely contributing to fewer injuries. It does, however, have its own problem.
Race walkers are conditioned athletes. The longest track and field event at the Summer Olympics is the 50-kilometer race walk, which is about five miles longer than the marathon. But the sport’s rules require that a race walker’s knees stay straight through most of the leg swing and one foot remain in contact (接触) with the ground at all times. It’s this strange form that makes race walking such an attractive activity, however, says Jaclyn Norberg, an assistant professor of exercise science at Salem State University in Salem, Mass.
Like running, race walking is physically demanding, she says, According to most calculations, race walkers moving at a pace of six miles per hour would burn about 800 calories(卡路里) per hour, which is approximately twice as many as they would burn walking, although fewer than running, which would probably burn about 1,000 or more calories per hour.
However, race walking does not pound the body as much as running does, Dr. Norberg says. According to her research, runners hit the ground with as much as four times their body weight per step, while race walkers, who do not leave the ground, create only about 1.4 times their body weight with each step.
As a result, she says, some of the injuries associated with running, such as runner’s knee, are uncommon among race walkers. But the sport’s strange form does place considerable stress on the ankles and hips, so people with a history of such injuries might want to be cautious in adopting the sport. In fact, anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper technique, she says. It takes some practice.
28. Why are race walkers conditioned athletes
A. They must run long distances. B. They are qualified for the marathon.
C. They have to follow special rules. D. They are good at swinging their legs.
29. What advantage does race walking have over running
A. It’s more popular at the Olympics. B. It’s less challenging physically.
C. It’s more effective in body building. D. It’s less likely to cause knee injuries.
30. What is Dr. Norberg’s suggestion for someone trying race walking
A. Getting experts’ opinions. B. Having a medical checkup.
C. Hiring an experienced coach. D. Doing regular exercises.
31. Which word best describes the author’s attitude to race walking
A. Skeptical. B. Objective. C. Tolerant. D. Conservative.

The connection between people and plants has long been the subject of scientific research. Recent studies have found positive effects. A study conducted in Youngstown，Ohio，for example, discovered that greener areas of the city experienced less crime. In another，employees were shown to be 15% more productive when their workplaces were decorated with houseplants.
The engineers at the Massachusetts Institute of Technology(MIT)have taken it a step further changing the actual composition of plants in order to get them to perform diverse，even unusual functions. These include plants that have sensors printed onto their leaves to show when they’re short of water and a plant that can detect harmful chemicals in groundwater. ＂We’re thinking about how we can engineer plants to replace functions of the things that we use every day,＂explained Michael Strano, a professor of chemical engineering at MIT.
One of his latest projects has been to make plants glow(发光)in experiments using some common vegetables. Strano’s team found that they could create a faint light for three-and-a-half hours. The light，about one-thousandth of the amount needed to read by，is just a start. The technology, Strano said, could one day be used to light the rooms or even to turn tree into self-powered street lamps.
In the future，the team hopes to develop a version of the technology that can be sprayed onto plant leaves in a one-off treatment that would last the plant’s lifetime. The engineers are also trying to develop an on and off＂switch＂where the glow would fade when exposed to daylight.
Lighting accounts for about 7% of the total electricity consumed in the US. Since lighting is often far removed from the power source(电源)—such as the distance from a power plant to street lamps on a remote highway-a lot of energy is lost during transmission(传输).
Glowing plants could reduce this distance and therefore help save energy.
32. What is the first paragraph mainly about
A. A new study of different plants. B. A big fall in crime rates.
C. Employees from various workplaces. D. Benefits from green plants.
33. What is the function of the sensors printed on plant leaves by MIT engineer
A. To detect plants’ lack of water B. To change compositions of plants
C. To make the life of plants longer. D. To test chemicals in plants.
34. What can we expect of the glowing plants in the future
A. They will speed up energy production.
B. They may transmit electricity to the home.
C. They might help reduce energy consumption.
D. They could take the place of power plants.
35. Which of the following can be the best title for the text
A. Can we grow more glowing plants
B. How do we live with glowing plants
C. Could glowing plants replace lamps
D. How are glowing plants made pollution-free

When you were trying to figure out what to buy for the environmentalist on your holiday list, fur probably didn’t cross your mind. But some ecologists and fashion (时装)enthusiasts are trying to bring back the market for fur made from nutria(海狸鼠).
Unusual fashion shows in New Orleans and Brooklyn have showcased nutria fur made into clothes in different styles. “It sounds crazy to talk about guilt—free fur unless you understand that the nutria are destroying vast wetlands every year”, says Cree McCree, project director of Righteous Fur.
Scientists in Louisiana were so concerned that they decided to pay hunters $5 a tail. Some of the fur ends up in the fashion shows like the one in Brooklyn last month.
Nutria were brought there from Argentina by fur farmers and let go into the wild. “The ecosystem down there can’t handle this non—native species(物种).It’s destroying the environment. It’s them or us.” says Michael Massimi, an expert in this field.
The fur trade kept nutria check for decades，but when the market for nutria collapsed in the late 1980s，the cat-sized animals multiplied like crazy.
Biologist Edmond Mouton runs the nutria control program for Louisiana. He says it’s not easy to convince people that nutria fur is green, but he has no doubt about it. Hunters bring in more than 300,000 nutria tails a year, so part of Mouton’s job these days is trying to promote fur.
Then there’s Righteous Fur and its unusual fashion. Morgan says，”To give people a guilt-free option that they can wear without someone throwing paint on them—I think that’s going to be a massive thing, at least here in New York.” Designer Jennifer Anderson admits it took her a while to come around to the opinion that using nutria fur for her creations is morally acceptable. She trying to come up with a label to attach to nutria fashions to show it is eco-friendly.
28. What is the purpose of the fashion shows in New Orleans and Brooklyn
A. To promote guilt-free fur. B. To expand the fashion market.
C. To introduce a new brand. D. To celebrate a winter holiday.
29. Why are scientists concerned about nutria
A. Nutria damage the ecosystem seriously. B. Nutria are an endangered species.
C. Nutria hurt local cat-sized animals. D. Nutria are illegally hunted.
30. What does the underlined word “collapsed” in paragraph 5 probably mean
A. Boomed. B. Became mature. C. Remained stable. D. Crashed.
31. What can we infer about wearing fur in New York according to Morgan
A. It’s formal. B. It’s risky. C. It’s harmful. D. It’s traditional.

We are the products of evolution, and not just evolution that occurred billions of years ago. As scientists look deeper into our genes (基因), they are finding examples of human evolution in just the past few thousand years. People in Ethiopian highlands have adapted to living at high altitudes. Cattle -raising people in East Africa and northern Europe have gained a mutation (突变) that helps them digest milk as adults.
On Thursday in an article published in Cell, a team of researchers reported a new kind of adaptation - not to air or to food, but to the ocean. A group of sea-dwelling people in Southeast Asia have evolved into better divers. The Bajau, as these people are known, number in the hundreds of thousands in Indonesia, Malaysia and the Philippines. They have traditionally lived on houseboats; in recent times, they’ve also built houses on stilts (支柱) in coastal waters. “They are simply a stranger to the land,” said Redney C. Jubilado, a University of Hawaii researcher who studies the Bajau.
Dr. Jubilado first met the Bajau while growing up on Samal Island in the Philippines. They made a living as divers, spearfishing or harvesting shellfish. “We were so amazed that they could stay underwater much longer than us local islanders,” Dr. Jubilado said. “I could see them actually walking under the sea.”
In2015, Melissa Ilardo, then a graduate student in genetics at the University of Copenhagen, heard about the Bajau. She wondered if centuries of diving could have led to the evolution of physical characteristics that made the task easier for them. “it seemed like the perfect chance for natural selection to act on a population,” said Dr. Ilardo. She also said there were likely a number of other genes that help the Bajau dive.
32. What does the author want to tell us by the examples in paragraph 1
A. Environmental adaptation of cattle raisers. B. New knowledge of human evolution.
C. Recent findings of human origin. D. Significance of food selection.
33. Where do the Bajau build their houses
A. In valleys. B. Near rivers C. On the beach. D. Off the coast.
34. Why was the young Jubilado astonished at the Bajau
A. They could walk on stilts all day. B. They had a superb way of fishing.
C. They could stay long underwater. D. They lived on both land and water.
35. What can be a suitable title for the text
A. Bodies Remodeled for a Life at Sea B. Highlanders’ Survival Skills
C. Basic Methods of Genetic Research D. The World’s Best Divers

When the explorers first set foot upon the continent of North America, the skies and lands were alive with an astonishing variety of wildlife. Native Americans had taken care of these precious natural resources wisely. Unfortunately, it took the explorers and the settlers who followed only a few decades to decimate a large part of these resources. Millions of waterfowl (水禽) were killed at the hands of market hunters and a handful of overly ambitious sportsmen. Millions of acres of wetlands were dried to feed and house the ever-increasing populations, greatly reducing waterfowl habitat (栖息地).
In 1934, with the passage of the Migratory Bird Hunting Stamp Act (Act), an increasingly concerned nation took firm action to stop the destruction of migratory (迁徙的) waterfowl and the wetlands so vital to their survival. Under this Act, all waterfowl hunters 16 years of age and over must annually purchase and carry a Federal Duck Stamp. The very first Federal Duck Stamp was designed by J.N. “Ding” Darling, a political cartoonist from Des Moines, lowa, who at that time was appointed by President Franklin Roosevelt as Director of the Bureau of Biological Survey. Hunters willingly pay the stamp price to ensure the survival of our natural resources.
About 98 cents of every duck stamp dollar goes directly into the Migratory Bird Conservation Fund to purchase wetlands and wildlife habitat for inclusion into the National Wildlife Refuge System — a fact that ensures this land will be protected and available for all generations to come. Since 1934, better than half a billion dollars has gone into that Fund to purchase more than 5 million acres of habitat. Little wonder the Federal Duck Stamp Program has been called one of the most successful conservation programs ever initiated.
28. What was a cause of the waterfowl population decline in North America
A. Loss of wetlands. B. Popularity of water sports.
C. Pollution of rivers. D. Arrival of other wild animals.
29. What does the underlined word “decimate” mean in the first paragraph
A. Acquire. B. Export. C. Destroy. D. Distribute.
30. What is a direct result of the Act passed in 1934
A. The stamp price has gone down. B. The migratory birds have flown away.
C. The hunters have stopped hunting. D. The government has collected money.
31. Which of the following is a suitable title for the text
A. The Federal Duck Stamp Story B. The National Wildlife Refuge System
C. The Benefits of Saving Waterfowl D. The History of Migratory Bird Hunting

An Australian professor is developing a robot to monitor the health of grazing cattle, a development that could bring big changes to a profession that's relied largely on a low-tech approach for decades but is facing a labor shortage.
Salah Sukkarieh, a professor at the University of Sydney, sees robots as necessary given how cattlemen are aging. He is building a four-wheeled robot that will run on solar and electric power. It will use cameras and sensors to monitor the animals. A computer system will analyze the video to determine whether a cow is sick. Radio tags (标签) on the animals will measure temperature changes. The quality of grassland will be tracked by monitoring the shape, color and texture (质地) of grass. That way, cattlemen will know whether they need to move their cattle to another field for nutrition purposes.
Machines have largely taken over planting, watering and harvesting crops such as corn and wheat, but the monitoring of cattle has gone through fewer changes.
For Texas cattleman Pete Bonds, it's increasingly difficult to find workers interested in watching cattle. But Bonds doesn't believe a robot is right for the job. Years of experience in the industry—and failed attempts to use technology—have convinced him that the best way to check cattle is with a man on a horse. Bonds, who bought his first cattle almost 50 years ago, still has each of his cowboys inspect 300 or 400 cattle daily and look for signs that an animal is getting sick.
Other cattlemen see more promise in robots. Michael Kelsey, vice president of the Oklahoma Cattlemen's Association, said a robot could be extremely useful given rising concerns about cattle theft. Cattle tend to be kept in remote places and their value has risen, making them appealing targets.
32. What is a problem with the cattle-raising industry
A. Soil pollution. B. Lack of workers.
C. Aging machines. D. Low profitability.
33. What will Sukkarieh's robot be able to do
A. Monitor the quality of grass. B. Cure the diseased cattle.
C. Move cattle to another field. D. Predict weather changes.
34. Why does Pete Bonds still hire cowboys to watch cattle
A. He wants to help them earn a living. B. He thinks men can do the job better.
C. He is inexperienced in using robots. D. He enjoys the traditional way of life.
35. How may robots help with cattle watching according to Michael Kelsey
A. Increase the value of cattle. B. Bring down the cost of labor.
C. Make the job more appealing. D. Keep cattle from being stolen.

During an interview for one of my books, my interviewer said something I still think about often. Annoyed by the level of distraction (干扰) in his open office, he said, “That’s why I have a membership at the coworking space across the street—so I can focus.” His comment struck me as strange. After all, coworking spaces also typically use an open office layout (布局). But I recently came across a study that shows why his approach works.
The researchers examined various levels of noise on participants as they completed tests of creative thinking. They were randomly divided into four groups and exposed to various noise levels in the background, from total silence to 50 decibels (分贝), 70 decibels, and 85 decibels. The differences between most of the groups were statistically insignificant; however, the participants in the 70 decibels group—those exposed to a level of noise similar to background chatter in a coffee shop—significantly outperformed the other groups. Since the effects were small, this may suggest that our creative thinking does not differ that much in response to total silence and 85 decibels of background noise.
But since the results at 70 decibels were significant, the study also suggests that the right level of background noise—not too loud and not total silence—may actually improve one’s creative thinking ability. The right level of background noise may interrupt our normal patterns of thinking just enough to allow our imaginations to wander, without making it impossible to focus. This kind of “distracted focus” appears to be the best state for working on creative tasks.
So why do so many of us hate our open offices The problem may be that, in our offices, we can’t stop ourselves from getting drawn into others’ conversations while we’re trying to focus. Indeed, the researchers found that face-to-face interactions and conversations affect the creative process, and yet a coworking space or a coffee shop provides a certain level of noise while also providing freedom from interruptions.
32. Why does the interviewer prefer a coworking space
A. It helps him concentrate B. It blocks out background noise
C. It has a pleasant atmosphere D. It encourages face-to-face interactions
33. Which level of background noise may promote creative thinking ability
A. Total silence B. 50 decibels C. 70 decibels D. 85 decibels
34. What makes an open office unwelcome to many people
A. Personal privacy unprotected B. Limited working space
C. Restrictions on group discussion D. Constant interruptions
35.What can we infer about the author from the text
A. He’s a news reporter. B. He’s on office manager.
C. He’s a professional designer. D. He’s a published writer.

In the fictional worlds of film and TV, artificial intelligence (AI) has been described as so advanced that it is indistinguishable from humans. But what if we're actually getting closer to a world where AI is capable of thinking and feeling
Tech company UneeQ is heading for its “digital humans”, which appear lifelike on the screen not only in terms of language, but also because of facial movements: raised eyebrows, a smile, even a nod. They look close to a human, but not quite.
What lies beneath UneeQ’s digital humans Their 3D faces are modeled on actual human features. Speech recognition enables them to understand what a person is saying, and natural language processing is used to work out a response. Meanwhile, another AI company, Soul Machines, is taking a more biological approach, with a “digital brain”, that imitates aspects of the human brain to adjust the emotions “felt” and “expressed” by its "digital people".
Shiwali Mohan, an AI scientist at the Palo Research Center, is skeptical of these digital beings. “They're humanlike in their looks and the way they sound, but that in itself is not being human,” she says. “Human qualities also involve how you think, how you approach problems, and how you break them down; and that takes a lot of algorithmic (算 法)design. Designing for human-level intelligence is a different attempt than designing images that behave like humans.”
She then continues, “If something looks like a human, we have high expectations of them, but they might behave differently in ways that humans just instinctively (直觉地)know how other humans react.”
Yet the demand is there, with UneeQ seeing high adoption of its digital employees across the financial, health care, and commercial sectors （行业）. “ Unless these sectors make their business models much more efficient digitally, they might be left behind,” says Chetan Dube, UneeQ’s CEO.
Some other companies are taking their digital beings a step further, enabling organizations and individuals to create digital humans themselves using free-access platforms they provide. “The biggest motivation for such platforms is to popularize AI,” Dube says.
Mohan is cautious about this approach, yet she supports the purpose behind these digital beings and is optimistic about where they are headed. “As we develop more advanced AI technology, we would then have to use new ways of communicating with that technology,”she says. “'Hopefully, all of that is designed to support humans in their goals.”
46. According to Para. 2, in what respect(s) do UneeQ’s "digital humans" resemble human beings
A. In the way they move around. B. In the way they act and react.
C. In observation and analysis. D. In speech and facial expressions.
47. Soul Machines’ digital brain is a technological breakthrough because it___________.
A. learns to make proper emotional responses
B. tends to imitate human beings' tone vividly
C. recognizes the speech sounds it receives
D. processes the natural language it hears
48. In Mohan’s opinion, what human quality is lacking in digital beings
A. Calculating brain. B. Language skills.
C. Instinctive judgements. D. Problem-solving ability.
49. What makes many sectors employ digital humans
A. The fear of falling behind in efficiency. B. The urgency to promote e-commerce.
C. The wish to spread digital technology. D. The need to upgrade the health care system.
50. What does Mohan think of the future of digital beings
A. It's well planned. B. It is promising.
C. It is uncertain. D. It's quite hopeless.

If you ever get the impression that your dog can “tell” whether you look content or annoyed, you may be onto something. Dogs may indeed be able to distinguish between happy and angry human faces, according to a new study.
Researchers trained a group of 11 dogs to distinguish between images (图像) of the same person making either a happy or an angry face. During the training stage, each dog was shown only the upper half or the lower half of the person’s face. The researchers then tested the dogs’ ability to distinguish between human facial expressions by showing them the other half of the person’s face or images totally different from the ones used in training. The researchers found that the dogs were able to pick the angry or happy face by touching a picture of it with their noses more often than one would expect by random chance.
The study showed the animals had figured out how to apply what they learned about human faces during training to new faces in the testing stage. “We can rule out that the dogs simply distinguish between the pictures based on a simple cue, such as the sight of teeth,” said study author Corsin Müller. “Instead, our results suggest that the successful dogs realized that a smiling mouth means the same thing as smiling eyes, and the same rule applies to an angry mouth having the same meaning as angry eyes.”
“With our study, we think we can now confidently conclude that at least some dogs can distinguish human facial expressions,” Müller told Live Science.
At this point, it is not clear why dogs seem to be equipped with the ability to recognize different facial expressions in humans. “To us, the most likely explanation appears to be that the basis lies in their living with humans, which gives them a lot of exposure to human facial expressions, and this exposure has provided them with many chances to learn to distinguish between them,” Müller said.
28. The new study focused on whether dogs can _________.
A. distinguish shapes B. make sense of human faces
C. feel happy or angry D. communicate with each other
29. What can we learn about the study from paragraph 2
A. Researchers tested the dogs in random order.
B. Diverse methods were adopted during training.
C. Pictures used in the two stages were different.
D. The dogs were photographed before the test.
30. What is the last paragraph mainly about
A. A suggestion for future studies. B. A possible reason for the study findings.
C. A major limitation of the study. D. An explanation of the research method.

Hundreds of scientists, writers and academics sounded a warning to humanity in an open letter published last December：Policymakers and the rest of us must engage openly with the risk of global collapse. Researchers in many areas have projected the widespread collapse as “a credible scenario（情景） this century”．
A survey of scientists found that extreme weather events，food insecurity，and freshwater shortages might create global collapse．Of course，if you are a non-human species，collapse is well underway．
The call for public engagement with the unthinkable is especially germane in this moment of still-uncontrolled pandemic and economic crises in the world's most technologically advanced nations．Not very long ago，it was also unthinkable that a virus would shut down nations and that safety nets would be proven so disastrously lacking in flexibility．
The international scholars' warning letter doesn't say exactly what collapse will look like or when it might happen．Collapseology，the study of collapse，is more concerned with identifying trends and with them the dangers of everyday civilization．Among the signatories（签署者）of the warning was Bob Johnson，the originator of the“ecological footprint”concept，which measures the total amount of environmental input needed to maintain a given lifestyle．With the current footprint of humanity，“it seems that global collapse is certain to happen in some form，possibly within a decade，certainly within this century，”Johnson said in an email．
Only if we discuss the consequences of our biophysical limits, the December warning letter says，can we have the hope to reduce their “speed，severity and harm”．And yet messengers of the coming disturbance are likely to be ignored．We all want to hope things will turn out fine．As a poet wrote，
Man is a victim of dope （麻醉品）
In the incurable form of hope．
The hundreds of scholars who signed the letter are intent（执着） on quieting hope that ignores preparedness．“Let's look directly into the issue of collapse，”hey say，“and deal with the terrible possibilities of what we see there to make the best of a troubling future．”
28. What does the underlined word“germane”in Paragraph 3 probably mean
A. Scientific． B. Credible． C. Original． D. Relevant．
29. As for the public awareness of global collapse，the author is__________．
A. worried B. puzzled C. surprised D. scared
30. What can we learn from this passage
A. The signatories may change the biophysical limits．
B. The author agrees with the message of the poem．
C. The issue of collapse is being prioritized．
D. The global collapse is well underway．

Over the last seven years, most states have banned texting by drivers, and public service campaigns have tried a wide range of methods to persuade people to put down their phones when they are behind the wheel.
Yet the problem, by just about any measure, appears to be getting worse. Americans are still texting while driving, as well as using social networks and taking photos. Road accidents, which had fallen for years, are now rising sharply.
That is partly because people are driving more, but Mark Rosekind, the chief of the National Highway Traffic Safety Administration, said distracted（分心）driving was "only increasing, unfortunately. "
"Big change requires big ideas. " he said in a speech last month, referring broadly to the need to improve road safety. So to try to change a distinctly modern behavior, lawmakers and public health experts are reaching back to an old approach: They want to treat distracted driving like drunk driving.
An idea from lawmakers in New York is to give police officers a new device called the Textalyzer. It would work like this: An officer arriving at the scene of a crash could ask for the phones of the drivers and use the Textalyzer to check in the operating system for recent activity. The technology could determine whether a driver had just texted, emailed or done anything else that is not allowed under New York's hands-free driving laws.
"We need something on the books that can change people's behavior,” said Félix W. Ortiz, who pushed for the state's 2001 ban on hand-held devices by drivers. If the Textalyzer bill becomes law, he said, "people are going to be more afraid to put their hands on the cell phone. "
8. Which of the following best describes the ban on drivers' texting in the US
A. Ineffective. B. Unnecessary. C. Inconsistent. D. Unfair.
9. What can the Textalyzer help a police officer find out
A. Where a driver came from. B. Whether a driver used their phone.
C. How fast a driver was going. D. When a driver arrived at the scene.
10. What does the underlined word "something" in the last paragraph refer to
A. Advice. B. Data. C. Tests. D. Laws.
11. What is a suitable title for the text
A. To Drive or Not to Drive Think Before You Start
B. Texting and Driving Watch Out for the Textalyzer
C. New York Banning Hand-Held Devices by Drivers.
D. The Next Generation Cell Phone: The Textalyzer

“What would the world be if there were no hunger ” It’s a question that Professor Crystal would ask her students. They found it hard to answer, she wrote later, because imagining something that isn’t part of real life—and learning how to make it real—is a rare skill. It is taught to artists and engineers, but much less often to scientists. Crystal set out to change that, and helped to create a global movement. The result—an approach known as systems thinking—is now seen as essential in meeting global challenges.
Systems thinking is crucial to achieving targets such as zero hunger and better nutrition because it requires considering the way in which food is produced, processed, delivered and consumed, and looking at how those things intersect (交叉 ) with human health, the environment, economics and society. According to systems thinking, changing the food system—or any other network—requires three things to happen. First, researchers need to identify all the players in that system; second, they must work out how they relate to each other; and third, they need to understand and quantify the impact of those relationships on each other and on those outside the system.
Take nutrition. In the latest UN report on global food security, the number of undernourished (营养不良) people in the world has been rising, despite great advances in nutrition science. Tracking of 150 biochemicals in food has been important in revealing the relationships between calories, sugar, fat and the occurrence of common diseases. But using machine learning and artificial intelligence, some scientists propose that human diets consist of at least 26,000 biochemicals—and that the vast majority are not known.This shows that we have some way to travel before achieving the first objective of systems thinking - which,in this example, is to identify more constituent parts of the nutrition system.
A systems approach to creating change is also built on the assumption that everyone in the system has equal power. But as some researchers find, the food system is not an equal one. A good way to redress (修正) such power imbalance is for more universities to do what Crystal did and teach students how to think using a systems approach.
More researchers, policymakers and representatives from the food industry must learn to look beyond their direct lines of responsibility and adopt a systems approach. Crystal knew that visions alone don’t produce results, but concluded that “we’ll never produce results that we can’t envision”.
28. The author uses the question underlined in Paragraph 1 to ________.
A. illustrate an argument B. highlight an opinion
C. introduce the topic D. predict the ending
29. What can be inferred about the field of nutrition
A. The first objective of systems thinking hasn’t been achieved.
B. The relationships among players have been clarified.
C. Machine learning can solve the nutrition problem.
D. The impact of nutrition cannot be quantified.
30. As for systems thinking, which would the author agree with
A. It may be used to justify power imbalance. B. It can be applied to tackle challenges.
C. It helps to prove why hunger exists. D. It goes beyond human imagination.

The benefits of regular exercise are well documented but there's a new bonus to add to the ever-growing list. New researchers found that middle-aged women who were physically fit could be nearly 90 percent less likely to develop dementia (失智症) in later life，and if they did，it came on a decade later than less sporty women.
Lead researcher Dr. Helena Horder, of the University of Gothenburg in Sweden, said,“These findings are exciting because it's possible that improving people's cardiovascular(心血管的) fitness in middle age could delay or even prevent them from developing dementia.”
For the study,191 women with an average age of 50 took a bicycle exercise test until they were exhausted to measure their peak（最大值的）cardiovascular capacity. The average peak workload was measured at 103 watts.
A total of 40 women met the criteria for a high fitness level, or 120 watts or higher. A total of 92 women were in the medium fitness category; and 59 women were in the low fitness category, defined as a peak workload of 80 watts or less, or having their exercise tests stopped because of high blood pressure, chest pain or other cardiovascular problems.
These women were then tested for dementia six times over the following four decades. During that time, 44 of the women developed dementia. Five percent of the highly fit women developed dementia, compared to 25 percent of the women with medium fitness and 32 percent of the women with low fitness.
"However, this study does not show cause and effect between cardiovascular fitness and dementia, it only shows an association. More research is needed to see if improved fitness could have a positive effect on the risk of dementia and also to look at when during a lifetime a high fitness level is most important." She also admitted that a relatively small number of women were studied, all of whom were from Sweden, so the results might not be applicable to other groups.
27.What is on the ever-growing list mentioned in the first paragraph

Many people believe that working to the maximum is the secret to success, but research has found that moderation(适度) also gets results on the job.
In a study led by Ellen Langer of Harvard University, researchers asked people to translate sentences into a new a made-up language. Subjects who practiced the language moderately beforehand made fewer errors than those who practiced extensively or not at all. High levels of knowledge can make people too attached to traditional ways of viewing problems across fields the arts, sciences, and politics. High conscientiousness is related to lower job performance, especially in simple jobs where it doesn’t pay to be a perfectionist.
How long we stay on the clock and how we spend that time are under careful examination in many workplaces. The young banker who eats lunch at his desk is probably seen as a go-getter, while his colleagues who chat over a relaxed conference-room meal get dirty looks from the corner office. “People from cultures that value relationships more than ours does are shocked by the thought of eating alone in front of a computer”, says Art Markman, a professor of psychology at the University of Texas, Austin. Social interaction has been shown to lift mood(情绪) and get people thinking in new directions and in ways that could help improve any post-lunch effort.
Markman also promotes off-task time. “Part of being a good thinker is experiencing things that are seemingly unrelated to what you are working on at the moment but give you fresh ideas about your work,” he says. “Also, there is a lot of research showing that a positive mood leads to higher levels of productivity and creativity. So, when people do things to increase their life satisfaction, they also make themselves more effective at work.”
27. What does Ellen Langer’s study show
A. It is worthwhile to be a perfectionist B.Translation makes people knowledgeable.
C. Simpler jobs require greater caution. D. Moderate effort produces the best result.
28. The underlined word “go-getter” in paragraph 3 refers to someone Who_______.
A. is good at handling pressure B. works hard to become successful
C. a has a natural talent for his job. D. gets on well with his co-workers
29. What can be inferred from the last paragraph
A. A good thinker is able to inspire other people.
B. Experience unrelated to your job is useless.
C. A cheerful mood helps make a creative mind.
D. Focusing on what you do raises productivity.
30. What does the text seem to advocate
A. Middle-of-the-road work habits. B. Balance between work and family.
C. Long-standing cultural traditions. D. Harmony in the work environment.

Race walking shares many fitness benefits with running, research shows, while most likely contributing to fewer injuries. It does, however, have its own problem.
Race walkers are conditioned athletes. The longest track and field event at the Summer Olympics is the 50-kilometer race walk, which is about five miles longer than the marathon. But the sport’s rules require that a race walker’s knees stay straight through most of the leg swing and one foot remain in contact (接触) with the ground at all times. It’s this strange form that makes race walking such an attractive activity, however, says Jaclyn Norberg, an assistant professor of exercise science at Salem State University in Salem, Mass.
Like running, race walking is physically demanding, she says, According to most calculations, race walkers moving at a pace of six miles per hour would burn about 800 calories(卡路里) per hour, which is approximately twice as many as they would burn walking, although fewer than running, which would probably burn about 1,000 or more calories per hour.
However, race walking does not pound the body as much as running does, Dr. Norberg says. According to her research, runners hit the ground with as much as four times their body weight per step, while race walkers, who do not leave the ground, create only about 1.4 times their body weight with each step.
As a result, she says, some of the injuries associated with running, such as runner’s knee, are uncommon among race walkers. But the sport’s strange form does place considerable stress on the ankles and hips, so people with a history of such injuries might want to be cautious in adopting the sport. In fact, anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper technique, she says. It takes some practice.
28. Why are race walkers conditioned athletes
A. They must run long distances. B. They are qualified for the marathon.
C. They have to follow special rules. D. They are good at swinging their legs.
29. What advantage does race walking have over running
A. It’s more popular at the Olympics. B. It’s less challenging physically.
C. It’s more effective in body building. D. It’s less likely to cause knee injuries.
30. What is Dr. Norberg’s suggestion for someone trying race walking
A. Getting experts’ opinions. B. Having a medical checkup.
C. Hiring an experienced coach. D. Doing regular exercises.
31. Which word best describes the author’s attitude to race walking
A. Skeptical. B. Objective. C. Tolerant. D. Conservative.

The connection between people and plants has long been the subject of scientific research. Recent studies have found positive effects. A study conducted in Youngstown，Ohio，for example, discovered that greener areas of the city experienced less crime. In another，employees were shown to be 15% more productive when their workplaces were decorated with houseplants.
The engineers at the Massachusetts Institute of Technology(MIT)have taken it a step further changing the actual composition of plants in order to get them to perform diverse，even unusual functions. These include plants that have sensors printed onto their leaves to show when they’re short of water and a plant that can detect harmful chemicals in groundwater. ＂We’re thinking about how we can engineer plants to replace functions of the things that we use every day,＂explained Michael Strano, a professor of chemical engineering at MIT.
One of his latest projects has been to make plants glow(发光)in experiments using some common vegetables. Strano’s team found that they could create a faint light for three-and-a-half hours. The light，about one-thousandth of the amount needed to read by，is just a start. The technology, Strano said, could one day be used to light the rooms or even to turn tree into self-powered street lamps.
In the future，the team hopes to develop a version of the technology that can be sprayed onto plant leaves in a one-off treatment that would last the plant’s lifetime. The engineers are also trying to develop an on and off＂switch＂where the glow would fade when exposed to daylight.
Lighting accounts for about 7% of the total electricity consumed in the US. Since lighting is often far removed from the power source(电源)—such as the distance from a power plant to street lamps on a remote highway-a lot of energy is lost during transmission(传输).
Glowing plants could reduce this distance and therefore help save energy.
32. What is the first paragraph mainly about
A. A new study of different plants. B. A big fall in crime rates.
C. Employees from various workplaces. D. Benefits from green plants.
33. What is the function of the sensors printed on plant leaves by MIT engineer
A. To detect plants’ lack of water B. To change compositions of plants
C. To make the life of plants longer. D. To test chemicals in plants.
34. What can we expect of the glowing plants in the future
A. They will speed up energy production.
B. They may transmit electricity to the home.
C. They might help reduce energy consumption.
D. They could take the place of power plants.
35. Which of the following can be the best title for the text
A. Can we grow more glowing plants
B. How do we live with glowing plants
C. Could glowing plants replace lamps
D. How are glowing plants made pollution-free

When you were trying to figure out what to buy for the environmentalist on your holiday list, fur probably didn’t cross your mind. But some ecologists and fashion (时装)enthusiasts are trying to bring back the market for fur made from nutria(海狸鼠).
Unusual fashion shows in New Orleans and Brooklyn have showcased nutria fur made into clothes in different styles. “It sounds crazy to talk about guilt—free fur unless you understand that the nutria are destroying vast wetlands every year”, says Cree McCree, project director of Righteous Fur.
Scientists in Louisiana were so concerned that they decided to pay hunters $5 a tail. Some of the fur ends up in the fashion shows like the one in Brooklyn last month.
Nutria were brought there from Argentina by fur farmers and let go into the wild. “The ecosystem down there can’t handle this non—native species(物种).It’s destroying the environment. It’s them or us.” says Michael Massimi, an expert in this field.
The fur trade kept nutria check for decades，but when the market for nutria collapsed in the late 1980s，the cat-sized animals multiplied like crazy.
Biologist Edmond Mouton runs the nutria control program for Louisiana. He says it’s not easy to convince people that nutria fur is green, but he has no doubt about it. Hunters bring in more than 300,000 nutria tails a year, so part of Mouton’s job these days is trying to promote fur.
Then there’s Righteous Fur and its unusual fashion. Morgan says，”To give people a guilt-free option that they can wear without someone throwing paint on them—I think that’s going to be a massive thing, at least here in New York.” Designer Jennifer Anderson admits it took her a while to come around to the opinion that using nutria fur for her creations is morally acceptable. She trying to come up with a label to attach to nutria fashions to show it is eco-friendly.
28. What is the purpose of the fashion shows in New Orleans and Brooklyn
A. To promote guilt-free fur. B. To expand the fashion market.
C. To introduce a new brand. D. To celebrate a winter holiday.
29. Why are scientists concerned about nutria
A. Nutria damage the ecosystem seriously. B. Nutria are an endangered species.
C. Nutria hurt local cat-sized animals. D. Nutria are illegally hunted.
30. What does the underlined word “collapsed” in paragraph 5 probably mean
A. Boomed. B. Became mature. C. Remained stable. D. Crashed.
31. What can we infer about wearing fur in New York according to Morgan
A. It’s formal. B. It’s risky. C. It’s harmful. D. It’s traditional.

We are the products of evolution, and not just evolution that occurred billions of years ago. As scientists look deeper into our genes (基因), they are finding examples of human evolution in just the past few thousand years. People in Ethiopian highlands have adapted to living at high altitudes. Cattle -raising people in East Africa and northern Europe have gained a mutation (突变) that helps them digest milk as adults.
On Thursday in an article published in Cell, a team of researchers reported a new kind of adaptation - not to air or to food, but to the ocean. A group of sea-dwelling people in Southeast Asia have evolved into better divers. The Bajau, as these people are known, number in the hundreds of thousands in Indonesia, Malaysia and the Philippines. They have traditionally lived on houseboats; in recent times, they’ve also built houses on stilts (支柱) in coastal waters. “They are simply a stranger to the land,” said Redney C. Jubilado, a University of Hawaii researcher who studies the Bajau.
Dr. Jubilado first met the Bajau while growing up on Samal Island in the Philippines. They made a living as divers, spearfishing or harvesting shellfish. “We were so amazed that they could stay underwater much longer than us local islanders,” Dr. Jubilado said. “I could see them actually walking under the sea.”
In2015, Melissa Ilardo, then a graduate student in genetics at the University of Copenhagen, heard about the Bajau. She wondered if centuries of diving could have led to the evolution of physical characteristics that made the task easier for them. “it seemed like the perfect chance for natural selection to act on a population,” said Dr. Ilardo. She also said there were likely a number of other genes that help the Bajau dive.
32. What does the author want to tell us by the examples in paragraph 1
A. Environmental adaptation of cattle raisers. B. New knowledge of human evolution.
C. Recent findings of human origin. D. Significance of food selection.
33. Where do the Bajau build their houses
A. In valleys. B. Near rivers C. On the beach. D. Off the coast.
34. Why was the young Jubilado astonished at the Bajau
A. They could walk on stilts all day. B. They had a superb way of fishing.
C. They could stay long underwater. D. They lived on both land and water.
35. What can be a suitable title for the text

When the explorers first set foot upon the continent of North America, the skies and lands were alive with an astonishing variety of wildlife. Native Americans had taken care of these precious natural resources wisely. Unfortunately, it took the explorers and the settlers who followed only a few decades to decimate a large part of these resources. Millions of waterfowl (水禽) were killed at the hands of market hunters and a handful of overly ambitious sportsmen. Millions of acres of wetlands were dried to feed and house the ever-increasing populations, greatly reducing waterfowl habitat (栖息地).
In 1934, with the passage of the Migratory Bird Hunting Stamp Act (Act), an increasingly concerned nation took firm action to stop the destruction of migratory (迁徙的) waterfowl and the wetlands so vital to their survival. Under this Act, all waterfowl hunters 16 years of age and over must annually purchase and carry a Federal Duck Stamp. The very first Federal Duck Stamp was designed by J.N. “Ding” Darling, a political cartoonist from Des Moines, lowa, who at that time was appointed by President Franklin Roosevelt as Director of the Bureau of Biological Survey. Hunters willingly pay the stamp price to ensure the survival of our natural resources.
About 98 cents of every duck stamp dollar goes directly into the Migratory Bird Conservation Fund to purchase wetlands and wildlife habitat for inclusion into the National Wildlife Refuge System — a fact that ensures this land will be protected and available for all generations to come. Since 1934, better than half a billion dollars has gone into that Fund to purchase more than 5 million acres of habitat. Little wonder the Federal Duck Stamp Program has been called one of the most successful conservation programs ever initiated.
28. What was a cause of the waterfowl population decline in North America
A. Loss of wetlands. B. Popularity of water sports.
C. Pollution of rivers. D. Arrival of other wild animals.
29. What does the underlined word “decimate” mean in the first paragraph
A. Acquire. B. Export. C. Destroy. D. Distribute.
30. What is a direct result of the Act passed in 1934
A. The stamp price has gone down. B. The migratory birds have flown away.
C. The hunters have stopped hunting. D. The government has collected money.

An Australian professor is developing a robot to monitor the health of grazing cattle, a development that could bring big changes to a profession that's relied largely on a low-tech approach for decades but is facing a labor shortage.
Salah Sukkarieh, a professor at the University of Sydney, sees robots as necessary given how cattlemen are aging. He is building a four-wheeled robot that will run on solar and electric power. It will use cameras and sensors to monitor the animals. A computer system will analyze the video to determine whether a cow is sick. Radio tags (标签) on the animals will measure temperature changes. The quality of grassland will be tracked by monitoring the shape, color and texture (质地) of grass. That way, cattlemen will know whether they need to move their cattle to another field for nutrition purposes.
Machines have largely taken over planting, watering and harvesting crops such as corn and wheat, but the monitoring of cattle has gone through fewer changes.
For Texas cattleman Pete Bonds, it's increasingly difficult to find workers interested in watching cattle. But Bonds doesn't believe a robot is right for the job. Years of experience in the industry—and failed attempts to use technology—have convinced him that the best way to check cattle is with a man on a horse. Bonds, who bought his first cattle almost 50 years ago, still has each of his cowboys inspect 300 or 400 cattle daily and look for signs that an animal is getting sick.
Other cattlemen see more promise in robots. Michael Kelsey, vice president of the Oklahoma Cattlemen's Association, said a robot could be extremely useful given rising concerns about cattle theft. Cattle tend to be kept in remote places and their value has risen, making them appealing targets.
32. What is a problem with the cattle-raising industry
A. Soil pollution. B. Lack of workers.
C. Aging machines. D. Low profitability.
33. What will Sukkarieh's robot be able to do
A. Monitor the quality of grass. B. Cure the diseased cattle.
C. Move cattle to another field. D. Predict weather changes.
34. Why does Pete Bonds still hire cowboys to watch cattle
A. He wants to help them earn a living. B. He thinks men can do the job better.
C. He is inexperienced in using robots. D. He enjoys the traditional way of life.
35. How may robots help with cattle watching according to Michael Kelsey
A. Increase the value of cattle. B. Bring down the cost of labor.
C. Make the job more appealing. D. Keep cattle from being stolen.

During an interview for one of my books, my interviewer said something I still think about often. Annoyed by the level of distraction (干扰) in his open office, he said, “That’s why I have a membership at the coworking space across the street—so I can focus.” His comment struck me as strange. After all, coworking spaces also typically use an open office layout (布局). But I recently came across a study that shows why his approach works.
The researchers examined various levels of noise on participants as they completed tests of creative thinking. They were randomly divided into four groups and exposed to various noise levels in the background, from total silence to 50 decibels (分贝), 70 decibels, and 85 decibels. The differences between most of the groups were statistically insignificant; however, the participants in the 70 decibels group—those exposed to a level of noise similar to background chatter in a coffee shop—significantly outperformed the other groups. Since the effects were small, this may suggest that our creative thinking does not differ that much in response to total silence and 85 decibels of background noise.
But since the results at 70 decibels were significant, the study also suggests that the right level of background noise—not too loud and not total silence—may actually improve one’s creative thinking ability. The right level of background noise may interrupt our normal patterns of thinking just enough to allow our imaginations to wander, without making it impossible to focus. This kind of “distracted focus” appears to be the best state for working on creative tasks.
So why do so many of us hate our open offices The problem may be that, in our offices, we can’t stop ourselves from getting drawn into others’ conversations while we’re trying to focus. Indeed, the researchers found that face-to-face interactions and conversations affect the creative process, and yet a coworking space or a coffee shop provides a certain level of noise while also providing freedom from interruptions.
32. Why does the interviewer prefer a coworking space
A. It helps him concentrate B. It blocks out background noise
C. It has a pleasant atmosphere D. It encourages face-to-face interactions
33. Which level of background noise may promote creative thinking ability
A. Total silence B. 50 decibels C. 70 decibels D. 85 decibels
34. What makes an open office unwelcome to many people
A. Personal privacy unprotected B. Limited working space
C. Restrictions on group discussion D. Constant interruptions
35.What can we infer about the author from the text
A. He’s a news reporter. B. He’s on office manager.
C. He’s a professional designer. D. He’s a published writer.

In the fictional worlds of film and TV, artificial intelligence (AI) has been described as so advanced that it is indistinguishable from humans. But what if we're actually getting closer to a world where AI is capable of thinking and feeling
Tech company UneeQ is heading for its “digital humans”, which appear lifelike on the screen not only in terms of language, but also because of facial movements: raised eyebrows, a smile, even a nod. They look close to a human, but not quite.
What lies beneath UneeQ’s digital humans Their 3D faces are modeled on actual human features. Speech recognition enables them to understand what a person is saying, and natural language processing is used to work out a response. Meanwhile, another AI company, Soul Machines, is taking a more biological approach, with a “digital brain”, that imitates aspects of the human brain to adjust the emotions “felt” and “expressed” by its "digital people".
Shiwali Mohan, an AI scientist at the Palo Research Center, is skeptical of these digital beings. “They're humanlike in their looks and the way they sound, but that in itself is not being human,” she says. “Human qualities also involve how you think, how you approach problems, and how you break them down; and that takes a lot of algorithmic (算 法)design. Designing for human-level intelligence is a different attempt than designing images that behave like humans.”
She then continues, “If something looks like a human, we have high expectations of them, but they might behave differently in ways that humans just instinctively (直觉地)know how other humans react.”
Yet the demand is there, with UneeQ seeing high adoption of its digital employees across the financial, health care, and commercial sectors （行业）. “ Unless these sectors make their business models much more efficient digitally, they might be left behind,” says Chetan Dube, UneeQ’s CEO.
Some other companies are taking their digital beings a step further, enabling organizations and individuals to create digital humans themselves using free-access platforms they provide. “The biggest motivation for such platforms is to popularize AI,” Dube says.
Mohan is cautious about this approach, yet she supports the purpose behind these digital beings and is optimistic about where they are headed. “As we develop more advanced AI technology, we would then have to use new ways of communicating with that technology,”she says. “'Hopefully, all of that is designed to support humans in their goals.”
46. According to Para. 2, in what respect(s) do UneeQ’s "digital humans" resemble human beings
A. In the way they move around. B. In the way they act and react.
C. In observation and analysis. D. In speech and facial expressions.
47. Soul Machines’ digital brain is a technological breakthrough because it___________.
A. learns to make proper emotional responses
B. tends to imitate human beings' tone vividly
C. recognizes the speech sounds it receives
D. processes the natural language it hears
48. In Mohan’s opinion, what human quality is lacking in digital beings
A. Calculating brain. B. Language skills.
C. Instinctive judgements. D. Problem-solving ability.
49. What makes many sectors employ digital humans
A. The fear of falling behind in efficiency. B. The urgency to promote e-commerce.
C. The wish to spread digital technology. D. The need to upgrade the health care system.
50. What does Mohan think of the future of digital beings
A. It's well planned. B. It is promising.
C. It is uncertain. D. It's quite hopeless.

If you ever get the impression that your dog can “tell” whether you look content or annoyed, you may be onto something. Dogs may indeed be able to distinguish between happy and angry human faces, according to a new study.
Researchers trained a group of 11 dogs to distinguish between images (图像) of the same person making either a happy or an angry face. During the training stage, each dog was shown only the upper half or the lower half of the person’s face. The researchers then tested the dogs’ ability to distinguish between human facial expressions by showing them the other half of the person’s face or images totally different from the ones used in training. The researchers found that the dogs were able to pick the angry or happy face by touching a picture of it with their noses more often than one would expect by random chance.
The study showed the animals had figured out how to apply what they learned about human faces during training to new faces in the testing stage. “We can rule out that the dogs simply distinguish between the pictures based on a simple cue, such as the sight of teeth,” said study author Corsin Müller. “Instead, our results suggest that the successful dogs realized that a smiling mouth means the same thing as smiling eyes, and the same rule applies to an angry mouth having the same meaning as angry eyes.”
“With our study, we think we can now confidently conclude that at least some dogs can distinguish human facial expressions,” Müller told Live Science.
At this point, it is not clear why dogs seem to be equipped with the ability to recognize different facial expressions in humans. “To us, the most likely explanation appears to be that the basis lies in their living with humans, which gives them a lot of exposure to human facial expressions, and this exposure has provided them with many chances to learn to distinguish between them,” Müller said.
28. The new study focused on whether dogs can _________.
A. distinguish shapes B. make sense of human faces
C. feel happy or angry D. communicate with each other
29. What can we learn about the study from paragraph 2
A. Researchers tested the dogs in random order.
B. Diverse methods were adopted during training.
C. Pictures used in the two stages were different.
D. The dogs were photographed before the test.
30. What is the last paragraph mainly about
A. A suggestion for future studies. B. A possible reason for the study findings.
C. A major limitation of the study. D. An explanation of the research method.

Hundreds of scientists, writers and academics sounded a warning to humanity in an open letter published last December：Policymakers and the rest of us must engage openly with the risk of global collapse. Researchers in many areas have projected the widespread collapse as “a credible scenario（情景） this century”．
A survey of scientists found that extreme weather events，food insecurity，and freshwater shortages might create global collapse．Of course，if you are a non-human species，collapse is well underway．
The call for public engagement with the unthinkable is especially germane in this moment of still-uncontrolled pandemic and economic crises in the world's most technologically advanced nations．Not very long ago，it was also unthinkable that a virus would shut down nations and that safety nets would be proven so disastrously lacking in flexibility．
The international scholars' warning letter doesn't say exactly what collapse will look like or when it might happen．Collapseology，the study of collapse，is more concerned with identifying trends and with them the dangers of everyday civilization．Among the signatories（签署者）of the warning was Bob Johnson，the originator of the“ecological footprint”concept，which measures the total amount of environmental input needed to maintain a given lifestyle．With the current footprint of humanity，“it seems that global collapse is certain to happen in some form，possibly within a decade，certainly within this century，”Johnson said in an email．
Only if we discuss the consequences of our biophysical limits, the December warning letter says，can we have the hope to reduce their “speed，severity and harm”．And yet messengers of the coming disturbance are likely to be ignored．We all want to hope things will turn out fine．As a poet wrote，
Man is a victim of dope （麻醉品）
In the incurable form of hope．
The hundreds of scholars who signed the letter are intent（执着） on quieting hope that ignores preparedness．“Let's look directly into the issue of collapse，”hey say，“and deal with the terrible possibilities of what we see there to make the best of a troubling future．”
28. What does the underlined word“germane”in Paragraph 3 probably mean
A. Scientific． B. Credible． C. Original． D. Relevant．
29. As for the public awareness of global collapse，the author is__________．
A. worried B. puzzled C. surprised D. scared
30. What can we learn from this passage
A. The signatories may change the biophysical limits．
B. The author agrees with the message of the poem．
C. The issue of collapse is being prioritized．
D. The global collapse is well underway．

Over the last seven years, most states have banned texting by drivers, and public service campaigns have tried a wide range of methods to persuade people to put down their phones when they are behind the wheel.
Yet the problem, by just about any measure, appears to be getting worse. Americans are still texting while driving, as well as using social networks and taking photos. Road accidents, which had fallen for years, are now rising sharply.
That is partly because people are driving more, but Mark Rosekind, the chief of the National Highway Traffic Safety Administration, said distracted（分心）driving was "only increasing, unfortunately. "
"Big change requires big ideas. " he said in a speech last month, referring broadly to the need to improve road safety. So to try to change a distinctly modern behavior, lawmakers and public health experts are reaching back to an old approach: They want to treat distracted driving like drunk driving.
An idea from lawmakers in New York is to give police officers a new device called the Textalyzer. It would work like this: An officer arriving at the scene of a crash could ask for the phones of the drivers and use the Textalyzer to check in the operating system for recent activity. The technology could determine whether a driver had just texted, emailed or done anything else that is not allowed under New York's hands-free driving laws.

“What would the world be if there were no hunger ” It’s a question that Professor Crystal would ask her students. They found it hard to answer, she wrote later, because imagining something that isn’t part of real life—and learning how to make it real—is a rare skill. It is taught to artists and engineers, but much less often to scientists. Crystal set out to change that, and helped to create a global movement. The result—an approach known as systems thinking—is now seen as essential in meeting global challenges.
Systems thinking is crucial to achieving targets such as zero hunger and better nutrition because it requires considering the way in which food is produced, processed, delivered and consumed, and looking at how those things intersect (交叉 ) with human health, the environment, economics and society. According to systems thinking, changing the food system—or any other network—requires three things to happen. First, researchers need to identify all the players in that system; second, they must work out how they relate to each other; and third, they need to understand and quantify the impact of those relationships on each other and on those outside the system.
Take nutrition. In the latest UN report on global food security, the number of undernourished (营养不良) people in the world has been rising, despite great advances in nutrition science. Tracking of 150 biochemicals in food has been important in revealing the relationships between calories, sugar, fat and the occurrence of common diseases. But using machine learning and artificial intelligence, some scientists propose that human diets consist of at least 26,000 biochemicals—and that the vast majority are not known.This shows that we have some way to travel before achieving the first objective of systems thinking - which,in this example, is to identify more constituent parts of the nutrition system.
A systems approach to creating change is also built on the assumption that everyone in the system has equal power. But as some researchers find, the food system is not an equal one. A good way to redress (修正) such power imbalance is for more universities to do what Crystal did and teach students how to think using a systems approach.
More researchers, policymakers and representatives from the food industry must learn to look beyond their direct lines of responsibility and adopt a systems approach. Crystal knew that visions alone don’t produce results, but concluded that “we’ll never produce results that we can’t envision”.
28. The author uses the question underlined in Paragraph 1 to ________.

The benefits of regular exercise are well documented but there's a new bonus to add to the ever-growing list. New researchers found that middle-aged women who were physically fit could be nearly 90 percent less likely to develop dementia (失智症) in later life，and if they did，it came on a decade later than less sporty women.
Lead researcher Dr. Helena Horder, of the University of Gothenburg in Sweden, said,“These findings are exciting because it's possible that improving people's cardiovascular(心血管的) fitness in middle age could delay or even prevent them from developing dementia.”
For the study,191 women with an average age of 50 took a bicycle exercise test until they were exhausted to measure their peak（最大值的）cardiovascular capacity. The average peak workload was measured at 103 watts.
A total of 40 women met the criteria for a high fitness level, or 120 watts or higher. A total of 92 women were in the medium fitness category; and 59 women were in the low fitness category, defined as a peak workload of 80 watts or less, or having their exercise tests stopped because of high blood pressure, chest pain or other cardiovascular problems.
These women were then tested for dementia six times over the following four decades. During that time, 44 of the women developed dementia. Five percent of the highly fit women developed dementia, compared to 25 percent of the women with medium fitness and 32 percent of the women with low fitness.
"However, this study does not show cause and effect between cardiovascular fitness and dementia, it only shows an association. More research is needed to see if improved fitness could have a positive effect on the risk of dementia and also to look at when during a lifetime a high fitness level is most important." She also admitted that a relatively small number of women were studied, all of whom were from Sweden, so the results might not be applicable to other groups.
27.What is on the ever-growing list mentioned in the first paragraph
A. Positive effects of doing exercises. B. Exercises suitable for the middle-aged.
C. Experimental studies on diseases. D. Advantages of sporty woman over man
28.Why did the researchers ask the woman to do bicycle exercise
A. To predict their maximum heart rate. B. To assess their cardiovascular capacity
C.To change their habits of working out D.To detect their potential heath problems
29.What do we know about Dr Horder's study
A. It aimed to find a cure for dementia. B. Data collection was a lengthy process.
C.Some participants withdrew from it. D.The results were far from satisfactory.
30.Which of the following is the best title for the text
A. More Women Are Exercising to Prevent Dementia

Many people believe that working to the maximum is the secret to success, but research has found that moderation(适度) also gets results on the job.
In a study led by Ellen Langer of Harvard University, researchers asked people to translate sentences into a new a made-up language. Subjects who practiced the language moderately beforehand made fewer errors than those who practiced extensively or not at all. High levels of knowledge can make people too attached to traditional ways of viewing problems across fields the arts, sciences, and politics. High conscientiousness is related to lower job performance, especially in simple jobs where it doesn’t pay to be a perfectionist.
How long we stay on the clock and how we spend that time are under careful examination in many workplaces. The young banker who eats lunch at his desk is probably seen as a go-getter, while his colleagues who chat over a relaxed conference-room meal get dirty looks from the corner office. “People from cultures that value relationships more than ours does are shocked by the thought of eating alone in front of a computer”, says Art Markman, a professor of psychology at the University of Texas, Austin. Social interaction has been shown to lift mood(情绪) and get people thinking in new directions and in ways that could help improve any post-lunch effort.
Markman also promotes off-task time. “Part of being a good thinker is experiencing things that are seemingly unrelated to what you are working on at the moment but give you fresh ideas about your work,” he says. “Also, there is a lot of research showing that a positive mood leads to higher levels of productivity and creativity. So, when people do things to increase their life satisfaction, they also make themselves more effective at work.”
27. What does Ellen Langer’s study show
A. It is worthwhile to be a perfectionist B.Translation makes people knowledgeable.
C. Simpler jobs require greater caution. D. Moderate effort produces the best result.
28. The underlined word “go-getter” in paragraph 3 refers to someone Who_______.
A. is good at handling pressure B. works hard to become successful
C. a has a natural talent for his job. D. gets on well with his co-workers
29. What can be inferred from the last paragraph
A. A good thinker is able to inspire other people.
B. Experience unrelated to your job is useless.
C. A cheerful mood helps make a creative mind.
D. Focusing on what you do raises productivity.
30. What does the text seem to advocate
A. Middle-of-the-road work habits. B. Balance between work and family.
C. Long-standing cultural traditions. D. Harmony in the work environment.
