A
Ask a smart home device for the weather forecast and it takes several seconds for the device to respond.This latency （延时） occurs as connected devices don't have enough memory or power to store and run the enormous machine-learning models needed for the device to understand what a user is asking of it.The model is stored in a data center that may be hundreds of miles away，where the answer is computed and sent to the device.
MIT researchers have created a new method for computing directly on these devices，which drastically reduces this latency.Their technique shifts the steps of running a machine-learning model to a central server where components of the model are encoded onto light waves.The waves are sent to a connected device using fiber optics （纤维光学），which enables tons of data to be sent lightning-fast through a network.The receiver then employs a simple optical device that rapidly performs computations using the parts of a model carried by those light waves.
This technique leads to more than a hundredfold improvement in energy efficiency when compared to other methods.It could also improve security，since a user's data do not need to be transferred to a central location for computation.This method could enable a self-driving car to make decisions in real-time while using just a tiny percentage of the energy currently required by power-hungry computers.It could also allow a user to have a latency-free conversation with their smart home device，be used for live video processing，or even enable high-speed image classification on a spacecraft millions of miles from Earth.
"Every time you want to run a neural network，you have to run the program，and how fast you can run the program depends on how fast you can pipe the program in from memory.Our pipe is massive — it corresponds to sending a full feature-length movie over the internet every millisecond or so.That is how fast data comes into our system.And it can compute as fast as that，" says professor Dirk England.
The neural network architecture involves storing weights in a central server that is connected to a novel piece of hardware called a smart transceiver.This smart transceiver，a thumb-sized chip（芯片），can receive and send data.Moving forward，the researchers want to update the smart transceiver chip to achieve even better performance.

Andrea Speranza wanted to be a firefighter long before she had the right word for her wish.After one childhood adventure at a construction site ended with an iron nail embedded （嵌入） in her leg and an emergency call to the fire department，she found herself in awe."As they gave me the medical treatment，I thought，they could help everybody and do anything，"says the now 52-year-old.
In 2000，Speranza fulfilled her dream of becoming a firefighter.Her job was exactly as fulfilling as she imagined it would be，except for one thing；she still hadn't seen another woman in her role—not in a magazine，not on television，not in real life.Speranza decided to help young women see that they，too，could have a career like hers.
The result is Camp Courage，an immersive （沉浸式的） program for girls aged 15 to 19 who want to learn more about firefighting，paramedicine and police work.In 2006，Speranza welcomed the first 17 participants.Over the course，the girls discover the ins and outs of being first responders：learning how to put out fires，delivering first aid and so on.
Camp Courage now nuns one session every year and is free to attend.To offset （抵消） costs，Speranza fundraises by holding everything from car washes to comedy nights.Campers must submit an essay describing how they plan to help their community，or a specific individual in need.And they have to deliver on the plan—from building a bench for a senior at a bus stop to launching a local chapter of the Kids Help Phone.
While Camp Courage is designed to help more women become first responders，Speranza also has another，bigger objective in mind：building leaders."If they can deliver a mechanical baby or climb a hundred-foot ladder，they're not going to have a problem going through a job interview，"says Speranza."It's a complete change in mindset，and it works."
Now hundreds of girls have passed through Camp Courage and some of them work as first responders now.Speranza feels a sense of achievement.The opportunity to recruit other girls to save lives alongside her keeps her going.It's not even measurable.
8. What inspired Speranza to become a firefighter？ ______
A. Her dream now. B. A childhood accident.
C. The lack of female firefighters. D. A firefighter's encouragement.
9. Why did Speranza decide to start Camp Courage？ ______
A. To train the girls to take the first aid course.
B. To complete an immersive program about firefighting.
C. To assist more females to take up some jobs like hers.
D. To motivate more females to stand on their own feet in the future.
10. What do campers have to do to pass through Camp Courage？ ______
A. Raise money to pay off the cost.
B. Submit an essay and deliver a speech.
C. Build a bench for the disabled at a bus stop.
D. Hand in a plan and then put it into action.

The coronavirus pandemic has created an environment for research on social connection.One of the most common areas of inquiry over the past couple of years was how our sudden mass shift to digital communication — away from face-to-face — affected overall social connectedness.Researchers studied nearly 3，000 adults during the pandemic's early months and found that email，social media，online gaming，and texting were not fungible for in-person interactions.Voice and video calls，were somewhat better.
Social connectedness is a key to happiness.Lower it，and you will be worse off — and so will your loved ones，especially your kids.One 2014 survey revealed that 62 percent of U.S.children thought their parents were too distracted to listen to them.The No.1 reason was parents' phone use.
It is clear that scrolling or surfing will reduce social connection：You do them instead of interacting.Virtual communications such as texting are by design interactive and should theoretically be less harmful.However，text messages can't convey emotion very well，because we can't hear or see our conversational partners.These technologies are to in-person interactions what a black-and-white，pixelated （像素化的） version of the Mona Lisa is to the real thing；identifiable，but incapable of producing the same emotional effects.
With communications on line，we tend to hop from person to person and thus swap depth for breadth.However，research has shown that deeper conversations bring more well-being than short communications.Meanwhile，in a recent study，teens who texted more often than their peers tended to experience more depression，more anxiety and poorer relationships with their fathers.
It might seem strange that we would voluntarily adopt technologies that hurt our happiness.One of the explanations is convenience.Vegetating （无所事事） in front of a screen is simply easier than talking with a person，and virtual communications such as texting are faster and easier than a visit or a phone call.Think of these technologies as grab-and-go food at a convenience store：It's not great，but it sure is easy — and after you eat enough microwave foods，you forget what the real thing tastes like.
In all，for most of us — especially people who grew up with it — the internet is an unquestioned part of the ecosystem of life.Quitting the virtual communications from our life is clearly not the answer.Since we're not going back to life before this kind of technology，we can and should use it mindfully in service of love.
12. What does the underlined word "fungible" most probably mean？ ______
A. Responsible. B. Changeable. C. Reliable. D. Replaceable.
13. As for virtual communications，the author is ______ .
A. disapproving B. doubtful C. supportive D. cautious
14. Which would be the best title for the passage？ ______
A. Virtual Communication Does Little Harm to People
B. Technology Can Make Your Relationships Shallower
C. Quitting Virtual Communication Is Just around the Corner
D. Technology Creates a Good Environment for Deeper Conversations

Born with severe hearing loss, Li has found her way to communicate with the world through painting.
Before learning to paint, Li always felt lonely in a silent world. She knew she was different from her peers because she could not hear. But a painting class in primary school opened for her a door to creativity and a way of expression.
“I still remember my first mural(壁画), which was to help a kindergarten to design and paint its wall.” Li says. “The project made me realize how happy I was immersing myself into painting.”
To pursue her passion for art, Li went to study advertising design at a vocational and technical school. “Painting brushes can help me create a colorful world in my imagination, telling my thoughts on paper, instead of through voices," Li said.
Graduating from college in 2005, Li got a job as a typist at a public institute. But she could not communicate well with her other colleagues. Her husband understood how she felt because he lost his hearing due to medication when he was 1 year old. He is also an art lover. In March 2016, under her husband s suggestion, Li quit her job and joined her husband s company, which specializes in 3D wall and ground paintings.
Wall painting is a demanding job because it requires people to work outdoors, whether in extremely cold or hot weather. As all the people are hearing-impaired in their company, communication with clients(客户) is the most common challenge that the team faces.
Now in many parks and scenic spots, the couple have created large-scale murals and interactive pavement painting that make onlookers a part of the drawings.
“My husband and I want to introduce painting to more people like us and help them find their own way to make a living,” Li says. Now Li has an apprentice（学徒） who just graduated from college. While coaching the newcomer, Li is exploring her own style and hopes to become an illustrator and open her own exhibition one day.
“They re energetic young people with a passion to create new things, and you can feel that in their paintings.” one of their clients said. “They re also a professional, dedicated team, often working late into the night on the designs for us.”
Li hopes that their stories can encourage more hearing-impaired people to build their own careers and achieve their goals, regardless of how tough it may be.
15. According to the passage, the painting class in primary school______________.
A. started Li s first advertising design
B. helped Li find a new way to express herself

When special occasions such as birthdays or other big holiday events come around，parents often look for that special toy for their children.But there is a growing understanding that gifts of time and bonding，such as vacations and other experiences，make better and more lasting gifts for children.
Experts agree that gifting children with memorable trips and fun experiences is better for their body and mind，and has corresponding positive impacts on the rest of the family!
In a 2017 study that surveyed about 500 women between 18 and 93 years old，Dr.Oravecz，a human development and family studies professor at Pennsylvania State University，asked，"Most people feel loved when..."The study showed that the most popular answers had nothing to do with any material item.Dr.Oravecz said，"Our research found that micro-moments of positivity，like a kind word，a hug with a child or a sympathetic expression，make people feel most loved."
Clinical psychologist Oliver James agrees.He stated that as opposed to toys，details from a trip are more likely to"stick with them for long after the vacation ends."When families interact in a stress-free environment，this creates warm，generous feelings towards one another，which are likely to be remembered with fondness.Vacations create strong emotional responses that don't often come with material possessions.
In addition，British child psychologist Dr.Margot Sunderland believes that vacations make children smarter."What is less widely known is that vacations can also advance brain development in children.This is because on a family vacation，you are exercising two genetically ingrained systems deep in the brain's limbic （边缘的） area，which can all too easily be'unexercised'in the home."Citing the work of neuroscientist Jaak Panksepp，Dr.Sunderland said，"These are the PLAY system and the SEEKING system.""The brain's PLAY system is exercised every time you bury your child's feet in the sand or take them for a ride on your back.The SEEKING system is exercised each time you go exploring together：the beach，a cave，a hidden village..."She continued，"So when you take your child on a vacation，you are supporting their explorative urge （SEEKING system）—a vital resource for living life well，and their capacity to play （PLAY system）.In adulthood，this translates into the ability to play with ideas—essential，for example，to the successful entrepreneur（企业家）."
In a busy household，perhaps the fun of having the latest toy may not last，but the space it occupies in the house could be there and gather dust.So for the next round of gift-giving with the children，consider an experiential gift instead.The return is definitely priceless.
19. From Dr.Oravecz's study，we know that ______ .
A. hearing kind words can make a person feel most loved
B. a special toy for a birthday is more lasting for children
C. women at the age of 18 and 93 years old feel more loved
D. the feeling of being loved is closely related to material gifts
20. What can be inferred from the passage？ ______
A. The capacity to play can translate into the ability to seek.
B. The SEEKING system can develop when adventuring in the wild.
C. PLAY and SEEKING systems are more easily exercised at home.
D. Burying your child's feet in the mud is exercising the SEEKING system.
21. According to the passage，the author may agree that ______ .
A. material gifts are better for a child's body and mind
B. children spending vacations with their parents are more generous
C. trips with family can form better emotional interactions than material gifts
D. vacations with employees are a waste of time for a successful entrepreneur

To help new students，the International Business Institute （IBI） plans to set up a buddy （伙伴） peer support project.The project will help new students meet current students at IBI who can provide them with some friendly company during their first months in Newcastle and help them with any small problems that they may have.
What's in it for you？
We believe that being a buddy will be rewarding in several ways.As a volunteer，it will be personally satisfying to know that you are able to help new students.It will also help you make contacts that may be valuable in your future academic and professional lives.If you are an overseas student，it will give you another opportunity to practise speaking English.
Responsibilities of buddies
Telephone and arrange to make contact with the new student.
Meet the student and show him/her around the campus and the local area.Answer questions about living in Newcastle and administration procedures at IBI.
Arrange to meet the new student one morning or afternoon one weekend early in the semester，and take the student to places that you enjoy in Newcastle.
Be prepared to take phone calls from the new student to answer further questions that he/she may have from time to time.Meet to explain information to the new student in person，if required.
You will be matched to an individual new student.However，if you have friends who are also buddies，you might prefer to form a support group together.This would mean that you meet the new students as a group rather than one-on-one.
Being a buddy is voluntary.There is no "requirement" to provide assistance beyond the help outlined above.
Please note that if you agree to become a peer support buddy，you will be expected to fulfil your role conscientiously and cheerfully.It will be important to be considerate and reliable so that the student can feel confident in your support.

Vast underwater meadows （草甸） of gently waving sea grass cover hundreds of miles up and down the West Coast.These blue-green fields perform a variety of important services.They protect the shoreline from erosion，clear pollutants from the water and provide habitats for all kinds of marine animals.
New research suggests sea grass meadows may also mitigate a serious consequence of greenhouse gas emissions：the steady acidification of ocean waters.The study published in the journal Global Change Biology finds that sea grass forests can raise pH levels in coastal waters.As they perform photosynthesis （光合作用），they remove carbon dioxide from the water，counteracting the acidifying effect of the gas.
"I think we are all very excited about it，"said lead study author Aurora Ricart，a scientist at the Bigelow Laboratory for Marine Sciences.
Ocean acidification is a side effect of rising carbon dioxide levels in the atmosphere.Some of this CO2 dissolves out of the air and into the sea，causing a chemical reaction that lowers the water's pH.Scientists sometimes refer to it as global warming's"evil twin"—an invisible companion to climate change.
Ocean acidification can have harmful effects on marine organisms like shellfish and coral by preventing them from properly forming the hard shells they need to survive.It's a threat both to natural ecosystems and to shellfish fisheries around the world.The study presents a natural way to address the problem.
Researchers analyzed six years of data from sea grass meadows spanning more than 600 miles off the California coastline.It focused on the common eelgrass，one of the most widespread sea grass species on the West Coast.The authors claim it's the largest，most comprehensive study of its kind.
According to the study，sea grass ecosystems can raise pH levels by more than 0.1 unit，equivalent to about a 30% decrease in acidity.The effect isn't constant.It comes in waves and is influenced by temperature，daylight，ocean currents and other factors that affect water chemistry and sea grass photosynthesis rates.But the tempering influence on acidification can be lasting，sometimes persisting for up to three weeks at a time.The study also shows that pH is higher in sea grass ecosystems，compared to nearby areas with no sea grass，about 65% of the time.
The study didn't investigate the effects of higher pH on marine organisms—that's a question for future research.But there's reason to believe these meadows may have a positive influence on shellfish and other ocean animals.
25. What can we learn from this passage？ ______
A. Sea grass forests can lower pH levels of coastal waters.
B. Shellfish and corals are not affected by ocean acidification.
C. Sea grass meadows can help remove pollutants from the sea water.
D. The effects of higher pH on marine organisms were investigated in this study.
26. What does the underlined word"mitigate"in Paragraph 2 probably mean？ ______
A. Relieve. B. Present. C. Cause. D. Predict.
27. Paragraph 7 tells us the research ______ .
A. findings B. process C. questions D. reflection
28. Why does the author write this passage？ ______
A. To illustrate the serious situation of climate change.
B. To present the living conditions of the underwater meadows.
C. To emphasize the importance of research on marine pollution.
D. To introduce a natural way to solve the problem of ocean acidification.

Many people have participated into lots of virtual meetings these years. Some research shows this adjustment might not impact workplace productivity to any great degree. A new study, though, suggests otherwise.
In the study, 602 participants were randomly paired and asked to come up with creative uses for a product. They were also randomly selected to work together either in person or virtually. The pairs were then ranked by assessing their total number of ideas, as well as those concepts degree of novelty, and asked to submit their best idea. Among the groups, virtual pairs came up with significantly fewer ideas, suggesting that something about face-to-face interaction generates more creative ideas. The findings could stiffen employers resolve to urge or require their employees to come back to the office.
“We ran this experiment based on the surprising feedback from companies that it was harder to innovate with remote workers,” said lead researcher Melanie Brucks. “Unlike other forms of virtual communication, like phone calls or e-mail, videoconferencing copies the in-person experience quite well, so I kind of disbelieved when we found meaningful differences between in-person and video interaction for idea generation.”
When random objects were placed in both the virtual and physical rooms, the virtual pairs of participants spent more time looking directly at each other rather than letting their look wander about the room and taking in the entire scene. Eyeing one s whole environment and noticing the random objects were associated with increased idea generation. On platforms, the screen occupies our interactions. Our look wavers less. “Looking away might come across as rude,” said Brucks,“so we have to look at the screen because that is the defined context of the interaction, the same way we wouldn t walk to another room while talking to someone in person.”
Like most educators, Brucks has primarily taught virtually in the past three years, and she did notice some benefits of the approach as well. Her students were more likely to take turns speaking and her shyer students spoke up more often, rid of the anxiety that comes from addressing a large classroom. Brucks found that one solution to improving virtual idea generation might be to simply turn off the camera, for her students felt "freer" and more creative when asked to do so. And this may be sound advice for the workplace Virtual teamwork can t replace face-to-face teamwork. Idea selection proficiency(能力) is only valuable if you have strong options to select from, and face-to-face teams are the best means to generate winning options. Perhaps the workplace will find a compromise— a sweet spot in the middle that balances working from both home and office.
29. What does the underlined word “stiffen” in Paragraph 2 most probably mean
A. Shake. B. Revise. C. Challenge. D. Strengthen.
30. At first, lead researcher Melanie Brucks might think that _______.
A. videoconferencing can t compare with in-person communication
B. participants should make eye contact in an online meeting
C. the feedback from companies seems questionable
D. creative ideas may emerge from casual thoughts
31. What can we learn about Brucks class
A. Her students relieved anxiety by speaking up.
B. Her students progressed in focusing attention.
C. Her students took advantage of virtual learning.
D. Her students displayed talent for public speaking.
32. Which of the following would be the best title for the passage
A. Interacting Virtually Impacts Working Participation
B. Maintaining Teamwork Improves Idea Generation
C. Grouping Randomly Increases Productivity
D. Brainstorming Online Limits Creativity

You may have heard of the Tasmanian tiger — but you most certainly have never seen one.Along with many other species over the past hundred years，this creature became extinct because of humans.Now，scientists in Australia and the US are trying to bring it back to life.
Bringing species back from the dead is known as de extinction.Though it sounds like something from a science fiction movie，new technologies have made de-extinction a very real possibility.To "bring back" an extinct species，scientists take stem cells from a closely related living animal and edit the genes.Then，the cells grow into a new animal.This new animal is not an exact copy of the extinct one，but it's very close.In theory，scientists could create entire populations of animals and set them free in the wild.
If successful，the de-extinction project in Australia could have a favorable impact on the environment.Tasmanian tigers could help bring balance to Australia's remaining forests by hunting and killing animals that are harming the trees.Indeed，something similar happened when wolves were reintroduced to Yellowstone Park in 1995，with deer and plant populations rebalanced as a result.
De-extinction is not a perfect solution，however.For one thing，it won't change the human behaviors that cause animals to become extinct in the first place.If we continue polluting and destroying the environment，animals will continue to die out.The only way we can truly protect them is by changing our habits.Bringing extinct species back to life won't magically make us respect nature more.
Also，the money that we spend on de-extinction would probably be better spent on other conservation projects.Or，as those against de-extinction would put it，it's better to spend money on the living rather than the dead.The reason for this is that，compared to other efforts，de-extinction is extremely expensive.In fact，for the cost of bringing one extinct species back to life，traditional conservation efforts could save up to eight threatened ones.
The power of science is amazing，but it might be time for us to stop and decide whether de-extinction is something we really want to achieve.With the technology we currently have，the question is no longer "can we？" but "should we？"

Remember your first day of school？How did your mum pick out your clothes the day before and how nervous did you feel when entering the classroom？Or what about the first time you rode a bike，with all of the excitement coursing through your veins（静脉）？Some memories stick with us and we can recall them like scenes in a movie.These are known as episodic memories.
A new study published in the journal，Proceedings of the National Academy of Sciences，has shown that certain cells，called time cells，make this type of memory possible.These cells help us form clear memories in chronological （时间顺序的） order.As memories are being formed，these time cells put a stamp on the memories.Later，this stamp helps us recount the exact sequence of events and experiences.
The 27 participants in the study had electrodes placed in their brains.This allowed scientists to measure cell activity in the hippocampus （海马体） and another area involved in the perception of time.The participants were shown sequences of 12 to 15 words on a computer screen in a period of about 30 seconds.Then they were asked to recall the words.During this time，the scientists looked at the activity of different brain cells.They found that specific cells fired signals during each sequence of words. "The time cells that we found are marking out discreet （不显眼的） segments （片段） of time within this approximately 30-second window，"said Brad Lega，a neurosurgeon at the University of Texas Southwestern Medical Center，US.This proves the possible existence of time cells in the human brain.
Gyorgy Buzsaki，a professor at New York University，said the study is important as it can explain memory problems found in people who suffered damage to their hippocampus.In one experiment，scientists compared the memories of people who had just taken a tour of a college campus.Those without damage to their hippocampus had similar stories.However，those who had suffered damage to this area of the brain were unable to recall the proper sequence of events.
The number of people suffering from memory disorders is increasing significantly.As of Sepetmber 2019，around 50 million people worldwide were suffering from dementia （痴呆），and the number will triple by 2050，according to the World Health Organization.Such studies will help scientists develop better medical interventions for people suffering from Alzheimer's disease，the cause of 60 to 70 percent of dementia cases.
42. What does the underlined word "recount" in Paragraph 2 probably mean？ ______
A. Decide. B. Tell. C. Create. D. Predict.
43. What can we learn from the study？ ______
A. Most of the participants could not recall the word sequence.
B. Participants were required to speak out the words within 30 seconds.
C. People with damaged hippocampus could also recall the sequence of events.
D. While the participants were recalling the words，certain brain cells released signals.
44. What does the study try to find out？ ______
A. How humans' feeling of time changes over time.
B. How often brain cells send signals during an event.
C. How brain cells work to remember sequences of events.
D. How the brain memorizes events that people have experienced.
45. What can the study be applied to？ ______
A. Finding the true cause of dementia.
B. Discovering time cells in creatures.
C. Finding ways to cure memory disorders.
D. Deciding the reason for Alzheimer's disease.

I still remember how a pet mouse was popular among my classmates in Broadbeach State School.One day，my friends and I decided to buy a pet mouse.The pet shopkeeper wouldn't sell us one until he got our parents' letter that could show their permission for us to get a pet.So，having the neatest handwriting，I faked one.The store owner quickly saw through my handwriting and asked me to contact my mother to confirm the situation.My trick quickly failed，and it was all messed up.
My mum got very angry and felt that the punishment should fit the crime.Knowing that my writing was poor and always in need of improvement，she made me write letters to a few randomly selected relatives.One of them was my uncle whom I'd only met a few times when I was a kindergartner.I wrote a long letter detailing my life and listing my interests.
My punishment was complete.I forgot about this until I suddenly got a reply from my uncle. "How lovely to hear from you，" he said，and went on to tell me all about his life.He'd love to hear about what subjects at school I enjoyed.And so started a correspondence（信件往来）that went on for several years.He turned out to be the most fascinating man.
Then out of the blue，he died.My mum took the phone call and she was shocked.She deeply regretted it as they had not really spoken for years because of their busy life and workload.I went upstairs and produced a box of letters，the last one being from just a few days before he had passed away.My mum began to read them and knew that although she hadn't been in touch，I had grown close to him by writing to him，which relieved and calmed her.In fact，I then became close to his wife，whom I also wrote to for many years.
I often think about how that one naughty childhood crime led to such an enriching correspondence that stretched on for many years.It encouraged me to write to lots of other people in fact，and it's something I keep up with to this day.Besides，receiving a letter is such a lovely surprise.Be bold and write to someone you maybe don't know that well.Who knows where it will lead？
46. Why did the author's mum ask him to write a letter to his uncle？ ______

Dear Teachers and Parents,
This June, during Financial Literacy Month, we have some to share.
In 2015, a free online financial education course named FutureSmart was introduced to middle school students, specifically intended for this group at a time in their lives when financial habits take hold and grow.
Fast forward to today, FutureSmart, available in English and Spanish, has reached over 13,000 schools across all 50 states. More than two million students have completed the course, with almost half coming from low-to-moderate income families.
But we aren t stopping there. We promise to reach four million more students by the end of 2025.
Why Because this moment calls for brave action. Never before have money management and investment decisions been so easy to conduct at any time or place through the use of a smartphone. It is time to offer students more critical financial literacy education to encourage them to make good financial decisions on a daily basis as they make their way through a complex world.
From weighing opportunity costs to delaying instant satisfaction for long-term financial gain, FutureSmart educates our youth using hands-on simulations (模拟) to introduce concepts like daily financial decisions and the rewards of long-term planning. Teaching young learners how to build solid financial foundations is an important step in building financially healthy communities.
Although our work is far from complete, we know that FutureSmart works. And it works exceptionally well.
In the largest study of its kind, supported by the MassMutual Foundation and EVERFI, the University of Massachusetts Donahue Institute (UMDI) recently concluded that 90% of students saw a statistically significant and educationally meaningful increase in knowledge after taking the FutureSmart course.
What s more, these results were consistent across all student demographics including race, age, gender, school year, and socioeconomic status.
We have a long way to go to reach every single middle school student, but we welcome the challenge. Together, our teams have started a movement to provide equal access to financial education, and we invite others to join us.
Visit to learn more and see how you can bring FutureSmart to the young people in your life.
MICHAEL FANNING RAY MARTINEZ
Head of MassMutual US President and Co-Founder of EVERFI

I was sitting in a chemistry lab class during my first year of university, nervous about the experiment we were to perform. I grabbed a pipette(吸液管) and, as I feared, my hand started to shake. The experience was disheartening: I was hoping to pursue a career in science, but I started to wonder whether that would be possible. I thought my dreams had crashed to the ground.
I was a boy born with brain damage. My family managed to find good doctors where we lived, in Leningrad (now St. Petersburg), Russia, and I took part in clinical trials testing new treatments. Shortly after my first birthday, I started walking and it became clear my intelligence function was unaffected. So, in some sense, I was lucky. Still, I couldn t do some things growing up. Both hands shook, especially when I was nervous or embarrassed. My left hand was much worse than my right, so I learned to write and do simple tasks with my right hand, but it wasn t easy to do anything precisely.
As a teenager, I faced a lot of bullying at school. Feeling alone, I joined a study group called “The natural world”. I thought that getting into the world of animals would keep me away from people. That s how I came into the field of biology. At university, I enjoyed the lectures in my science classes. Many lab tasks proved impossible, however. As I struggled with my mood, I read a book about depression. From then on, the physiology of mental disorders became my scientific passion. I looked into what was being done locally and was excited to discover a lab that did behavioral experiments in rats to study depression.
At the end of my second year, I approached the professor of the lab to see whether I could work with her. I was afraid to admit I couldn t do some lab tasks. To my relief, she was completely supportive. She set me to work performing behavioral experiments for others in the lab with the help of colleagues. I loved the supportive atmosphere and stayed there to complete my master s and Ph. D.
I ve come to realize that my hands aren t the barrier I thought they were. By making use of my abilities and working as part of a team, I ve been able to follow my passions. I ve also realized that there s much more to being a scientist than performing the physical labor. I may not collect all the data in my papers, but I m fully capable of designing experiments and interpreting results, which, to me, is the most exciting part of science.
53. What was the author s dream
A. To live a normal life. B. To become a scientist.

A. he didn't lose the function of both hands
B. he learned how to walk at the age of teenager
C. his family could afford to see good doctors
D. his brain damage didn t affect his intellectual capacity
55. What can be inferred from the passage
A. the author s own depression inspired him to help others with mental disorders
B. the author was surrounded by a team who urged him to further his study
C. the author s loneliness moved him towards the world of biology
D. the author finally finished the lab tasks on his own
56. What message does the author want to express
A. Loving yourself makes a difference.
B. Opportunity follows prepared people.
C. A bright future begins with a small dream.
D. The sun somehow shines through the storm.

Clown fish live their adult lives in the protective arms of sea anemones, the small brightly colored sea animals attached onto rocks to house clown fish. Between birth and adulthood, however, the fish have to complete a treacherous journey. After hatching, they swim out to the open sea to finish developing. After maturing, the young fish swim back, during which they have to avoid a “wall of mouths” by sensing the unfriendly smells. With ocean acidification, a trend that is occurring worldwide, scientists began to wonder what might happen to fish s sense of smell.
My team put 300 recently hatched clown fish in our lab. When we introduced a friendly fish odor (气味), they did not react. But when we introduced an enemy odor, they swam away. We then repeated the experiment with 300 new hatchlings from the same parents in the more acidic water-a level we can expect by the year 2100 if current trends continue. When we introduced friendly and unfriendly smells at the same time, the fish seemed unable to make up their minds, spending equal time swimming toward one smell and the other. They could sense chemical signals but couldn t recognize the meaning of them.
It is always tricky to say that behaviors seen in a lab would also be seen in the wild. So we went to a sandy lake near one of the Great Barrier Reef s northern islands to test how wild-caught damselfish would react to enemy smells after exposing them to acidic water. In a tank, about half of them held in water with acidity expected by 2050 were attracted to the unfriendly odor and half were not, yet not one held in water anticipated by 2100 avoided being attracted to the enemy odor. We then let the marked damselfish loose in the lake. The fish once held in the most acidic water swam farther away from their protective home. Can fish adapt Most studies have habituated fish to lifted acidic conditions over a few days or months-an extremely short length of time. The animals are not given a realistic opportunity to adapt. Yet some scientists thought that fish might escape the anger of ocean acidification, in part because early research done in the 1980s showed that certain animals had an astonishing ability to regulate their internal chemistry to survive acidified water. But maintaining normal functions such as avoiding danger is a different challenge.
At a minimum, confusion could place yet another stressor on fish already challenged by rising water temperatures, overfishing, etc. Further, if many ocean creatures start to behave strangely, entire food webs and ecosystems could come crashing down. Although the science is still new, the results appear to be lining up: ocean acidification is messing with fish s minds.
60. What does the underlined word “treacherous” in Paragraph 1 probably mean
A. Risky. B. Hurried. C. Mysterious. D. Helpless.
61. What can we learn about the fish in the acidic water
A. They lost their senses to chemical signals.
B. They were less likely to respond to threats.
C. Their behavior in the lab disappeared in the wild.
D. They tended to seek the protection from their home.
62. What can be inferred from the passage
A. The author s study confirms previous findings.
B. Fish s adaptation to acidic water is a matter of time.
C. Different fishes behave differently to acidity change.
D. The chances of restoring fish s minds are yet to be seen.
63. Which of the following would be the best title for the passage
A. What Do Different Stressors Do to Ocean Creatures
B. What Does Ocean Acidity Mean to Ocean Creatures
C. How Does Ocean Acidification Destroy the Ecosystem

Arguably, the biggest science development of the year to date has been the images of the very depths of the universe taken by the James Webb Space Telescope (JWST). Those images beg a comparison between the external and internal universes that science is bent on observing and understanding.
Decades ago, astrophysicist Carl Sagan famously said, “The universe is also within us. We re made of star-stuff. We are a way for the universe to know itself. ” He was commenting then on the reality that our internal universe was as complex and as fantastic as the outer space.
There are many similarities between the progress we ve made in understanding the universe and in piecing together life s inner workings. Like the technological developments that took us from Galileo s telescope to the Hubble to the JWST, life science tools have also improved rapidly. From early light microscopes to modern super-resolution ones, these developments have afforded researchers a deep look into biology s infinitesimal (无限小的) landscape. Learning that living things were composed of cells was, not a terribly long time ago, a revolutionary observation. Since then, scientists have been able to dive ever deeper into the components of life.
Going beyond merely observing the complicated makeup of organisms, life scientists can now discover the workings of molecules (分子). And that is where scanning the universe differs from peering into biology. Understanding the universe, especially from a functional standpoint, is not necessarily an immediate urgency. Understanding biology on that level is. Simply observing the amazing internal structure of cells is not enough. Biologists must also characterize how all those parts interact and change in different environments and when faced with various challenges. Being able to image a virus or bacterium is nice at the level of basic science. But knowing how viruses gain entry into cells and spread, infect, and disable can literally save lives. Through time, biology has risen to this mechanistic challenge. Not only can life science tools produce images of cell components, even more importantly, they can help predict the effects of drugs on receptors, of immune cells on foreign invaders (入侵者), and of genetic perturbations (基因干扰) on development and aging.
This is not to belittle the work of scientists researching into universe. They should rightly be praised for delivering views of impossibly distant, impossibly massive phenomena. My aim is to celebrate these accomplishments while at the same time recognizing that science s inward search for detail and insight is equally impressive and, in my view, more urgent. The output of both the outward and inward explorations should stimulate wonder in everyone. After all, it s all star-stuff.
64. Why does the author quote Carl Sagan s comment in Paragraph 2
A. To introduce the background. B. To prove an assumption.
C. To make a comparison. D. To present an idea.
65. Like the study of the universe, life science has been advancing in ________.
A. study approaches B. system management
C. research facilities D. technology integration
66. We can infer from Paragraph 4 that biologists work is ________.
A. practical B. risky C. flexible D. popular
67. As for life science, which would the author agree with
A. It has received universal recognition.
B. It should enjoy priority in development.
C. It can be applied in the majority of areas.
D. It is more complicated than space science.
