It’s true that people learn for as long as they live. But with age, one’s learning ability becomes weak. Luckily, there’re some learning suggestions that can help you take in more knowledge.
________ The brain remembers things better if they’re written down. Let’s say you’re thinking about ways to deal with bad PR (公共关系). If you develop a method in your mind alone, it’s possible that you’ll forget some parts. However, written notes and mind maps will allow you to remember and explain your method.
Go for short learning periods. Humans can’t focus on anything for too long. So instead of wasting your time and energy on long learning periods, go for short learning periods. It helps the brain take in information better.
Share knowledge. Share what you know and you may have a better understanding of it. Simply talking about what you’ve learned will help make your confusion (疑惑) clear. Besides, the person you’re sharing your knowledge with might point out (指出) a big mistake you made. Even if none of these happens, you do teach some people and learn from others.
Follow a role model. This will make your mind believe your goal can be achieved. Even if you don’t have the same story as your role model, they will serve as a motivation (动力) to keep you working hard. For example, a person who learned a foreign language in one month will be the perfect role model to follow if you want to learn a new language in a short time.
All these learning suggestions are, luckily, extremely simple to include in your life. With them, you can get to the top of the ladder of success one step at a time!

Note-taking is a skill that can help you do well in all your schoolwork. It can make you confident（自信的） when you are studying. But unluckily, most students don't know how to take notes. Here is some advice on how to take notes.
Write down key facts. If your teacher writes notes on the blackboard, that's great. You can copy them or write down the most important facts of all in class. Different teachers do things differently. For example, some teachers may focus on（关注） lots of dates and facts in class, but they only write the important ones on the blackboard. Other teachers may not write anything down, but they may say something important again and again.
Ask. Don't be afraid to ask your teacher to repeat what you missed. If your teacher speaks too fast and you can't follow what he is saying, you can ask him after class.
paring your notes with your classmates' can be good for your learning. It can also help you and your classmates correct（纠正） some mistakes.
Organize. Note-taking also needs organization. Keep notes for each subject in one notebook, so that you can find everything easily when a test comes.
Good note-taking takes time. If you decide to recopy your notes every evening, you'll surely have less time to watch TV. But you'll save time in the coming test.
5．What should you write down in your notebook in class
A．Every word. B．Lots of dates. C．The most important facts.
6．Which way can help you correct mistakes in your notes
A．Organizing the notes. B．Asking your teachers for help. C．Comparing your notes with others’.
7．What's the best title for this text
A．How to take notes B．What to do in class C．What to do with problems
Chemistry is usually thought to be more difficult than other subjects, at least for the beginners. There are some reasons for this idea. For one thing, chemistry has very specialized vocabulary (专用语汇). At first, studying chemistry is like learning a new language. Also, some concepts (概念) of chemistry are hard to understand. However, with hard work and careful study, you can learn this subject successfully—and even enjoy it. Here are some suggestions to help you develop good study habits and better understand the topics in the book:
·Firstly, attend classes on time. Listen to your teacher and take careful notes in class. If possible, always review the topics you have learned in class, and review your notes on the same day.
·Secondly, think carefully whether you really understand the meaning of a term or the use of an equation (方程式). A good way to test your understanding is to explain a concept to a classmate or someone else.
·Thirdly, pay attention to things which have something to do with chemistry in life. Watch or do experiments in class carefully.
·Fourthly, question often and do not be afraid to ask your teacher or classmates for help.
You will find that chemistry is much more than numbers, formulas (分子式) and equations. It’s often used in daily life just like math and physics. Once you fall in love with it, you’ll get lots of fun.
8．How many suggestions does the writer give the readers
A．Three. B．Four. C．Five. D．Six.
9．The writer thinks that a good way to test your understanding of the formula “H2CO3” is to _______.
A．write it on the blackboard B．read it aloud in class
C．explain it to someone else D．ask others the meaning of it
10．According to the passage, which of the following is true
A．Chemistry is more often used than physics.
B．Some concepts of chemistry are hard to understand.
C．Studying chemistry is like learning our mother language.
D．Chemistry is usually thought to be as difficult as other subjects.
11．The passage is mainly about _______.
A．differences between chemistry and physics

D．how students study chemistry
Did you know that vocabulary is more important than grammar If you have good vocabulary, you can communicate successfully, even if the grammar is not completely perfect.
However, one common problem is learning new words and then forgetting them. So when you want to use a new word in a conversation, you can’t remember it at that moment. Does this often happen to you The reason for this difficulty is that most students try to learn vocabulary by studying lists and dictionaries and remembering the words. But it may not work if you don’t have a very good memory.
The best way to learn vocabulary and remember the words successfully is to learn new words and use them at once. You can do this with a very simple exercise. Every time you learn a new word, for example, from an English lesson or an article, write it down in your vocabulary notebook. Writing is more active than just reading a definition (释义). You should write the word, the definition in English or translation, one example sentence from the article or dictionary and one example sentence that you create.
Imagine you just learn the word “generous”, write in your vocabulary notebook: generous (adjective), definition—giving or willing to give freely. Example one, from the article: Thanks for paying for my dinner, you’re very generous. Example two, my example: My brother is generous because he volunteers at the animal shelter on weekends. It’s best if your example sentences are true to your life, because this creates a personal connect ion with the new word. The next day, read your vocabulary note book again and try to add one more example sentence using the new word. It’s helpful for you to remember it: These two simple steps—writing the word and using it at once—help you remember and use new words.
Do you have a vocabulary notebook If not, start now.
12．What does the underlined word “it” in Paragraph 2 refer to
A．The problem. B．The new word. C．The conversation.
13．What’s the correct order of the following steps of taking vocabulary notes
①Make your own example sentence.
②Write the word, its English definition or translation.
③Copy an example sentence from the article or dictionary.
④Read your notebook again and add one more example sentence.
A．②③①④ B．②③④① C．③②①④
14．How can we make the best example sentences according to the writer
A．By connecting them with our life.
B．By adding words from the article.
C．By explaining words’ definitions.
15．Which of the following opinion will the writer most probably agree with
A．Vocabulary is not so important as grammar.
B．Reading a definition is more active than writing.
C．The best way to remember new words is to use them.
16．What’s the best title for the passage
A．Ways of Learning New Words
B．Abilities of Creating Examples
C．Suggestions on Using Grammar

Students usually have to spend a lot of time learning knowledge, but the learning outcome cannot always meet what we expect. 17 Here, let’s try Feynman’s learning method. As the name suggests, it was proposed by a Nobel Prize winner Richard Feynman (理查德 费曼). It is an effective (有效的). 18
First of all, choose a concept (概念) as your learning aim. Read the material and try to understand it.
19 For example, suppose you are trying to explain the concept to a 5-year-old boy. You use simple language in order to make him fully understand it.
If you have trouble explaining it clearly, then come to the third step. 20 Explain it to the boy bit by bit in your own words until he completely understands it.
Finally, you should be able to answer questions about the concept. 21 Feynman thinks that understanding is more important than memorizing. His learning method encourages students to think deeply and solve problems with their own understanding.
A．There are four main steps included.
B．Why can’t we make big progress in a short time
C．That is possibly because you don’t have good learning methods.
D．Review the material and divide it into smaller parts.
E．Third, move to another concept and work harder on it.
F．Try to teach it to more people and be ready to answer any of their questions.
G．Next, explain it to others.

I like reading different kinds of books, such as novels, science books, and history books. My favorite book is “The Little Prince”. It is a very interesting story about a little prince who travels to different planets. I like it because it teaches me about love and friendship.
Reading has many benefits. It can improve my vocabulary and writing skills. It can also help me relax after a long day of studying. Sometimes, when I am sad or stressed, reading a good book can make me feel better.

Books can be the best friend. But do you know how to enjoy reading books
Look for books in a library or a big bookstore. You can also ask friends if you can borrow their books.
If you find a good book, read the first page to see how to read it. Do not start to read it until you have the time. It is best for you to wait until you finish your homework.
Sit in a comfortable chair or sofa. Have a lamp on the back of you, lighting the room where you are reading. And then you do not have to get up soon after starting to read.

Times change! The day I heard that the Bright Bookstore was closing, I was sad. The bookstore had been in the neighborhood for 50 years, and it was a great place where people could connect through their love of books. When I met Old Tim, the store’s owner, he told me it was difficult to run a traditional bookstore. Most young people liked reading e-books better and more people bought books online.
Childhood memories came back to me so clearly. A group of us kids often went to the store. We looked at the new books, or just talked with Tim. We spent hours reading there. Tim encouraged us to share our ideas by writing them on a large board.
A few months later, I came back and was surprised to see that the Bright Bookstore was still open for business. It was still old, but inside it was like a different world. In an area, a book reading was going on. Nearby, some readers were sharing their ideas on a screen instead of the large board. Some were reading on computers. It even had a coffee shop selling nice food. Clearly, the Bright Bookstore was in good, creative hands. Tim told me that there were more community (社区) events in the coffee shop such as book readings and even concerts and movie nights. The bookstore was turned into a place where the book lovers got together and shared ideas and experiences. “I’m so glad to see that everything I wanted it to offer to the community is still here,” said Tim. No matter how times change, there are always people who love reading. With the development of technology, traditional bookstores should also change in a creative way.

Most of us enjoy stories—whether it’s reading an interesting storybook or listening to a friend tell a story. But do you know that writing stories can also be good for you
June 23rd is National Writing Day in the UK—a celebration of creative writing. It’s also a chance to understand the advantages (优点) of creative writing and using your imagination.
Creative writing comes from your imagination. Fiction is a good example of creative writing. Fiction describes imaginary (虚构的) events and people. However, fiction isn’t the only form (形式) of creative writing. Plays, films or TV shows are also forms of creative writing.
Many people find creative writing makes them feel relaxed because they’re expressing thoughts and feelings that they’ve kept in their mind. According to the Anna Freud National Center for Children and Families, writing about a character’s feelings can make it easier to understand your own feelings. They also say that creative writing can be a useful tool for taking care of yourself.
Another advantage is that it can make people feel good about themselves. It can help people realize that their voice is important and powerful. Mark Haddon, a writer, says, “It’s more than learning a skill. It’s about learning that you, your family, your culture and your opinion of the world are interesting and important.”
For many people, creative writing offers a chance to get away from real life. This can help you think more about good things in your life or simply allow you to go into a magical and peaceful world.
35．What can we learn from Paragraph 1
A．Everyone should read stories. B．Stories are not strange to most of us.
C．Writing stories can be good for reading. D．Listening to a story is not as interesting as telling a story.
36．How many forms of creative writing are mentioned in Paragraph 3
A．One. B．Two. C．Three. D．Four.
37．What is Paragraph 4 mainly about
A．How to start creative writing. B．Ways to improve creative writing.
C．How to express thoughts and feelings. D．The influence (影响) of creative writing on feelings.
38．Which is NOT the advantage of creative writing
A．People can feel relaxed. B．People will become smarter.
C．People think more good things. D．People can realize they themselves are important.
39．What is the purpose (目的) of the text
A．To encourage people to read more stories. B．To show us that creative writing is useful.
C．To tell us the importance of being creative. D．To introduce the advantages of National Writing Day.
The Power of Active Reading: A Better Way to Learn Reading is an important skill for students—it helps you learn new knowledge, improve vocabulary, and understand the world better. But not all reading is the same. Many students read passively: they just move their eyes across the page, but don’t think deeply about what they’re reading. This kind of reading doesn’t help you remember or understand information well. Active reading, however, is a more effective learning method that can help you get more out of every book or article.
So what is active reading It means engaging with the text while you read—asking questions, taking notes, and connecting ideas. Here are some key steps to active reading. First, before you read, set a goal. Ask yourself: “What do I want to learn from this text ” For example, if you’re reading a history chapter about the Industrial Revolution, your goal might be to understand its main causes and effects. Setting a goal helps you stay focused and avoid getting distracted.
Second, while reading, take notes. You can underline important sentences, write down key terms, or jot down questions you have. For example, if you read that “steam engines changed manufacturing,” you can note: “Steam engines—key to Industrial Revolution, made production faster.” Taking notes helps you remember information and makes it easier to review later. It also forces you to think about what’s important in the text.
Third, ask questions as you read. Good questions include: “Why did this happen ” “How does this connect to what I already know ” and “Do I agree with the author’s point ” For example, if you’re reading a science article about climate change, you might ask: “How do human activities affect climate change ” Asking questions keeps your mind active and helps you understand the text more deeply.
Fourth, after reading, review and reflect. Go back to your notes and answer the questions you wrote down. You can also summarize the main ideas of the text in your own words. For example, after reading a novel chapter, you might summarize: “The main character decided to leave home to pursue her dream, but she was worried about her family.” Reflecting on what you’ve read helps you organize information and remember it for a longer time.
Active reading takes more time and effort than passive reading, but it’s worth it. It helps you learn better, remember more, and think critically. Whether you’re reading a textbook, a novel, or a news article, active reading can improve your learning experience. Try it next time you read—you’ll be surprised at how much more you get out of the text.
40．What is passive reading
A．Engaging with the text by asking questions. B．Taking notes while reading.
C．Moving eyes across the page without deep thinking. D．Summarizing the text after reading.
41．Why is setting a goal important for active reading
A．It helps you stay focused and avoid distraction. B．It helps you finish reading faster.
C．It helps you avoid taking notes. D．It helps you read more books.
42．What can you do while reading to practice active reading
A．Only move your eyes across the page. B．Take notes and ask questions.
C．Ignore difficult words and sentences. D．Read the text quickly without stopping.
43．What should you do after active reading
A．Forget about the text and move to the next one. B．Blame yourself for not reading fast enough.
C．Throw away your notes. D．Review notes and reflect on the text.
44．What is the main advantage of active reading
A．It takes less time than passive reading. B．It lets you read more books at once.
C．It helps you learn better and remember more. D．It helps you avoid difficult texts.
You don’t have to be old to be an inventor. Frank Epperson invented the Popsicle when he was just eleven years old. One winter day in 1905, after a day of play, he left his drink outside with the stir stick (搅拌棒), he found his drink was frozen like an icicle (冰柱). Frank tasted it and found it was delicious. And it became a hit with his friends.
When he grew up, Frank Epperson sold land and houses for a living. By 1921 he had to make a living for his wife and five children. But Frank never forgot the frozen treat (冰品) that he had discovered. He decided to continue with it. He soon started a business—selling the frozen treats in seven flavours (口味). He named the ice on a stick “Epsicle”. His children didn’t think that was a very good name. They called the frozen treat “Pop’s sicle”. The name was later changed to “Popsicle”. In 1924 Frank got a patent (专利) for his frozen treat.
During the late 1920s and the 1930s, the United States went through hard times. Many people lost their jobs. Twin ice pops (双棒棒冰) with two sticks were invented. They were just five cents and two children could share them.
Today millions of Popsicles are sold every year. They come in thirty flavours. The most popular flavour is cherry. Now whenever we enjoy ice pops in summer, we have Frank Epperson to thank.

When Emily Cummins was four years old, her grandfather gave her a hammer (锤子). She loved using it, and started to learn how to make toys from old things that nobody used any more.
50 She always thought a lot about making inventions to help other people. Emily’s grandfather had an illness. He had a lot of pain in his hands and fingers. One day, Emily saw that he had trouble getting toothpaste (牙膏) out of the tube. She made an invention that helped him with this, and won the Young Engineer for Britain Award for her toothpaste dispenser (挤牙膏器).
A few years later, Emily learned about the serious water shortage (短缺) in some African countries. The women and children there often walk many kilometers a day to get water for their villages. They usually put the buckets (桶) on their heads, and they have to walk carefully in order not to spill (溅出) the water. 51 It makes it possible for the women to transport up to five buckets each time. Besides, it is easy for them to repair the water carrier when it is broken as it is made of wood.

The rubber (橡胶) raincoat was invented by Macintosh in 1823.
In 1492, Columbus discovered the New World the Americas. He brought a lot of things from South America. Rubber was one of them, but people didn’t know the use of rubber at that time. In 1770, people found that the rubber could be used as erasers.
Macintosh was a worker in an eraser factory in England. One day he spilled (洒出) the rubber liquid (液体) over his clothes carelessly when making erasers. He was too busy to clean it and went back home wearing the dirty clothes. On the way home, it rained heavily. Having no umbrella, Macintosh had to run home quickly. When he got home, he took off the wet clothes. To his surprise, the area of the clothes with rubber wasn’t wet. “Why not make a rubber raincoat ” Macintosh thought. The next day he brushed the rubber liquid all over a coat. He wore the “rubber coat” on rainy days and took a walk outdoors, to test if it could really keep off the rain. Surprisingly, the clothes inside the “rubber coat” weren’t wet at all. The rubber raincoat was created in this way by chance.

Teachers find it difficult for students to collect the homework before class, sometimes they may even get mad. To solve this problem, a 13-year-old middle school student Zhang from Shenzhen invented a smart robot and he got the first prize in the 20th Guangdong Provincial Children’s Invention Awards (奖项). His parents are so proud of him.
This efficient robot can collect homework in a short time without making any mistakes. It uses radio frequency identification (RFID，射频识别) technology—a reader and a special tag (标签) that can share information without touching each other. This way, it can help find and know what it is looking for. Each student’s notebook has a special RFID tag with their name and the subject. Students only need to place their notebooks on the robot, and the machine “sees” the notebook, reads its tag and takes it out of the name list. Teachers can check who hasn’t turned in homework by connecting their phones with the robot through Wi-Fi.
Many teachers speak highly of the robot after using it and they think Zhang will create more useful AI tools to make life easier. His parents will continue to support him. Inspired by the words, Zhang dreams of becoming a scientist when he grows up. “I have tried making model airplanes and other scientific and creative projects. Inventing has brought me joy and happiness,” he said.
59．What kind of award did Zhang win
A．Art. B．Music. C．Invention. D．Sports.
60．If teachers use the robot to collect homework, it will help ________.

About 150 years ago, the French writer Jules Verne showed what the future would be like in some of his books. He once said, “Anything one man can imagine, other men can make it come true.” Now, let’s take a look at the future in the eyes of some scientists.
Underwater (水下的) cities: As the world’s population increases, there’s less space for us to build houses. So, it’s believed that one day we could live underwater. By the year 2050, underwater cities could come out. These underwater buildings will be made of special material. It is possible for us to make the rooms bigger or smaller.
3 D printed (打印) foods: Many scientists believe that 3 D dishes will be the future of food. In the future, many kitchens may have a 3 D printer. And the best part is that 3 D printed foods can always have the same tastes as the recipes (配方).
Flying cars: Heavy traffic is a common problem today, and people have dreamed of flying cars. In the future, flying cars will be as common as bicycles. These flying cars will be something between a helicopter (直升机) and a plane. People will spend less time on traffic, probably cutting a 2 -hour taxi ride into a 15 -minute one.

There are two kinds of squirrels (松鼠) in the UK: the red squirrel and the grey squirrel. However, the population of red squirrels has become smaller since the last century. This is mainly because grey squirrels have made the life of red squirrels more difficult. Grey squirrels are bigger and stronger, so they are better at competing for food and areas to live. Grey squirrels also carry a virus (病毒). This virus doesn’t harm grey squirrels, but it can be dangerous for red squirrels.
However, scientists have developed a system (系统) to help boost red squirrel numbers. And it uses artificial intelligence (AI). AI is a computer that has learned from experience and can do things that usually need human intelligence. The AI system has been trained to look at photos of squirrels and tell red squirrels from grey squirrels. The aim of the system is to help red squirrels by giving them more food, while stopping grey squirrel population from getting even bigger. To stop grey squirrel population getting bigger, the AI system can offer grey squirrels a kind of special food that stops them having babies. Scientists check the AI has recognized grey squirrels properly.
What’s next Scientists think the AI could also be taught to recognize squirrels by their whiskers (胡须). This could help scientists follow squirrels more closely. For example, if a red squirrel gets sick, the AI could let scientists know quickly.
With the help of AI, the number of red squirrels might rise soon. “This isn’t just about squirrels,” Dr. Smith, a wildlife scientist, says. “It’s also about learning to protect wildlife with technology.”

Chinese scientists research in Antarctica
风雪中的艰辛：他在南极研究气候
In the white, icy world of Antarctica (南极), Chinese scientists worked hard in the freezing cold to do research. On April 10, the country’s 40th Antarctic scientific expedition (考察) team returned home after finishing their tasks.
“Our main jobs in Antarctica were to watch the weather and to build weather stations,” said Zhu Kongju. The 33-year-old was a member of the expedition team and is an engineer at the Chinese Academy of Meteorological Sciences (CAMS, 中国气象科学研究院).
Zhu and his teammates did tests on greenhouse gases and the ozone (臭氧层) in Antarctica. They wanted to see how climate change is affecting (影响) the area. They also set up two weather stations that can work in extremely (极度地) cold conditions and fixed the ones already there, increasing the area they could watch.
The hardest part of working in Antarctica was dealing with “surprises” from the weather, Zhu said.u They traveled and moved supplies (物资) every day using snowmobiles (雪地摩托) and sleds (雪橇). “One day, because of a big snow storm, we could barely see three meters ahead, and if we left the snowmobile, we’d get lost right away. We had to yell through the intercom (对讲机) and use GPS to tell each other where we were,” he said. “It took us four hours that day just to get the snowmobiles parked together.”
Although the work was very tough, the scientists managed to collect important data (数据) for their research. “The frozen (冰冻的) parts of Earth are really important for the world’s energy and water. Antarctica is a big player in the world’s climate,” Zhu said. Even though few people live there, its weather changes a lot with the world’s climate, which makes it a key place to study climate change.

Computer scientist Mary has an idea for a new robot to help her work with children. How should it look The robot should have arms to be able to lift things. And if it is going to communicate with people, it will also need a face. Scientists believe that giving a robot a face can make it seem more friendly. Humans would also like to pay more attention to robots with faces. But what kind
For Mary, she wants to make sure that her new robot doesn’t look too much like a human. She wants people to just treat it as a machine-person. If it looks more like a human than a machine, she thinks users might find it a bit creepy and feel afraid. Mary also believes that robot faces don’t need to look a lot like ours. Her research shows that we can enjoy communicating with robots whether or not they look like humans, because our brains are able to look for faces. Just put two circles on top of a robot’s body, and we will see a face.
Dave feels differently. He believes that although at first we might be afraid when seeing a robot with a lifelike face, we may soon get used to it. If robots are going to work closely with humans, they should look as much like us as possible. After all, faces are an important part of the way we communicate.
To make his robots look as much like real people as possible, Dave invented a special skin (皮肤) for their faces. With this skin, robots can show human-like expressions and appear to be angry, sad, happy or surprised. Dave’s robots are also programmed to copy expressions. How Just imagine his robot is looking at you. The cameras in its eyes send pictures of your face to its central computer!
78．Why do scientists think a robot needs a face
A．It will become more beautiful. B．It can do better in lifting things.
C．It will pay more attention to children. D．It can better communicate with people.
79．What does the underlined word “creepy” mean in paragraph 2
A．Uncomfortable to look at. B．Impossible to touch.
C．Boring to talk to. D．Difficult to understand.
80．Which of the following would Dave most probably agree with
A．People should treat robots as humans.
B．Robots need to express their own feelings.
C．Robots shouldn’t look too much like humans.
D．People can easily accept robots with a human face.

Have you ever seen a train that is hung in the air Such a train has appeared in Chengdu already.
The train is powered by lithium batteries (锂电池) instead of electricity. It is not only energy-saving but also environmentally friendly compared to other trains. Each coach (车厢) will be able to carry up to 120 passengers.
The train has done its test without any problem a short time ago. But further tests will be done to check the train’s ability to turn and climb up the tracks before it can be open to the public.
Chengdu is the first city in our country to build such a train system, and Shanghai will also open one this year. Shanghai started plans for its “Skytrain” in 2015.
The “Skytrain” in Shanghai will run above the ground at a height of around six meters. The columns (柱) which will support the railway will be just 80 cm wide. The columns are so narrow that they could even be built in the green belt in the middle of the road. The train Shanghai plans to use will have just four coaches, and each coach will hold 70 passengers. The train will run at around 30 kilometers per hour. It will be a little slower than the city’s subway trains, which run between 30 and 40 kilometers per hour.
“Skytrain” would cost about 120 to 150 million yuan to build. Developers said the train system will carry around 15, 000 passengers every hour. The space-saving train system would run silently through the city.
82．What test will be done
A．The train’s largest speed.
B．The train’s ability to carry passengers.
C．The distance the train can run without stopping.
D．The train’s ability to turn and climb up the tracks.
83．How many passengers can such a train in Shanghai carry
A．280. B．420. C．120. D．70.
84．Compared to other trains, what are the advantages of this new kind of train
①running very fast ②saving energy ③saving space ④ little noise
⑤environmentally friendly ⑥carrying more passengers
A．①②③④ B．②③④⑤ C．③④⑤⑥ D．①②⑤⑥
85．The passage mainly tells us ________.
A．the advantages of a new kind of train
B．the cost of building a new kind of train
C．a new kind of train and its development in China
D．the number of passengers that different kinds of trains can carry
Scientists in Switzerland have used lasers (激光) to change the path of a lightning strike (雷击的路径). The experiment suggests that in the future, lasers might be useful for protecting large buildings from lightning.
Lightning can be extremely powerful and cause serious problems on the ground. Lightning strike can cause fires, destroy buildings, and even kill people. The damage from lightning costs billions of dollars every year. In the US, lightning strikes killed close to 450 people between 2006 and 2021.
Scientists have been trying to find a way to protect buildings from lightning for a long time. Now the best Way is by putting metal rods (金属竿) on the buildings. These rods are connected to the ground. The lightning is attracted to the rods, which safely guide the electricity into the ground. But lightning rods can only protect a small area. Some buildings—such as airports are so large that it’s difficult to protect the whole building using lightning rods.
Another idea is to use lasers to guide lightning. Scientists had been working on the idea for over 20 years. They have successfully guided lightning with lasers inside a lab. But until the summer of 2021, scientists could guide lightning with lasers outside. Using a powerful laser, scientists in Switzerland were able to guide lightning tor meters.
The heat from the laser creates a path of air that is less thick than the air around it. The path also has a special charge (电荷). The lightning can follow this path almost as if it were a lightning rod. Scientist Matteo Clerici said, “The fact that we managed to do it in an outdoor environment is a very big step.”
But the laser still didn’t guide the lightning as far as the scientists would like. Besides, the laser is also very expensive. The scientists say it cost about $2 billion. It will probably take 10 or more years before a laser like this is truly able to protect large buildings.
86．To know how powerful lightning can be, which paragraph can we read
A．Paragraph 2. B．Paragraph 3. C．Paragraph 4. D．Paragraph 5.
87．What is the laser technology expected to protect
A．High-rise buildings. B．Large buildings.
C．Beautiful buildings. D．Important buildings.
88．Why are lasers not used widely for changing the path of lightning strike now
A．Putting metal rods on the buildings is the best way.
B．Some buildings are so large that it’s difficult to protect.
C．Lasers are only able to guide lightning for a short distance
D．Lasers are so expensive that scientists can’t pay for experimenting.
89．What can we learn from what Matteo Clerici said
A．Scientists still need to work harder to achieve a greater success.
B．It is not easy for scientists to guide lightning with lasers outside.
C．Scientists need to change working environment in next experiments.
D．It is a great progress for scientists to guide lightning with lasers outside.
90．What can we get to know at the end of the passage
A．Behind bad luck comes good luck.
B．A journey of a thousand miles begins with a single step.
C．There is still a long way to go before a laser can really work.
D．For scientists, working together is better than working alone.
