1 . Forty-five minutes was considered an appropriate amount of time to supply 12-year-old me — and 20 other teenagers — with enough information about eating disorders to last us through high school. A documentary shown on a dusty VHS tape that had obviously been in use since the early 2000s, about two girls suffering from anorexia and bulimia, had been my only source for eating disorder awareness for five years. No reflection time followed, no discussion was started, and no questions were asked.
Flash forward five years I still know nothing. It wasn’t until I was 16 that I learned, via TikTok, that my daily diet of 1,000 calories is barely enough for a two-year-old, let alone a developing teenager. Despite being educated in America’s sixth best county in education, I only had a single image of what an eating disorder looked like: a skin-and-bones teenage girl with sunken eyes. Schools are clearly ill-equipped to educate students on eating disorders and how they can prevent them.
Teenagers have failed to learn about the most common eating disorder in the country because it isn’t taught in many school curriculum: binge eating disorder (暴食症). It is more common than anorexia, affecting 2.8 million Americans, including 1.2 percent of all adolescents. Additionally, it’s reported that males make up 40 percent of those with binge eating disorder, which contradicts the existing opinion that only women are affected by eating disorders.
Instead of learning about eating disorders, my junior health class taught me how to count my calories. According to registered dietitian Christy Harrison, “disordered eating patterns began with calorie counting.” Despite this, health classes across the country continue to require students to track their daily calorie intake.
We need a developed and well-informed eating disorder curriculum. After all, the damage of a seemingly harmless 45-minute video may last someone a lifetime.

2 . Soft robots that have no batteries, motors or electronics and that are powered and controlled from a distance by light or magnets（磁铁）are a popular field of research. But there are barriers to overcome before they can be used in practical applications, including the need for a cheap manufacturing process.
Zhang Li at the Chinese University of Hong Kong and his colleagues discovered that a magnet-controlled robot can be created easily and at low cost.
In experiments, his team created sticky tape robots of various shapes around a centimetre across that change their geometry depending on the presence and direction of a magnetic field. Some of the robots were able to move through water or along flat surfaces and one device was able to crawl（爬）across the surface of pie stomach tissue in the lab and place a small therapeutic patch（补丁）onto a gastric ulcer（胃溃疡）before leaving the patch and moving away.
Zhang says that these devices could be used in the future to deliver drugs or carry out simple medical procedures in the stomach or intestines. “It can be used in this kind of folded, small scale, and when it reaches a large empty space it can open up,” he says. “It’s very much like a satellite, where after its launch into outer space the solar panels will open up. So when you swallow this device, it should have a very small size.”
There are hurdles to overcome prior to clinical trials, however. “The first thing is safety, because currently we’re using a very strong magnet called a neodymium-iron-boron magnet. It’s actually not that safe,” says Zhang. “It’s kind of toxic to the cells.”
1. What is paragraph 3 mainly about?| A．How the robots function. | B．What changes the robots’ geometry. |
| C．Whether the robots are marketable. | D．What inspired the creation of the robots. |
| A．By citing clinical trials. | B．By analyzing cause and effect. |
| C．By quoting wise sayings. | D．By comparing it to something similar. |
| A．Harmless. | B．Complicated. | C．Poisonous. | D．Flexible. |
| A．Soft Robots Make Your Life Convenient. |
| B．Soft Robots Can Crawl Inside Your Organs. |
| C．Soft Robots Are Ready for Cheap Production. |
| D．Soft Robots Can Perform Complex Operations. |
3 . Advertising in mass media is powerful. Right ads help create demands of products, campaign for political candidates or ideas and historically, even start wars. Detailed files the social media Companies build for each user, however, make advertising even more powerful by enabling advertisers to tailor their messages to individuals. These files even include your family size and whether you buy a lot of beer.
Consequently, social media has greater abilities to expose people to ideas as fast as they’ll individually accept them. The same ticks that can commend products to just the right person or suggest something addictive just when someone is most fragile can also suggest an extreme Conspiracy (阴谋) theory just when he is ready to consider it.
It’s increasingly common for friends and family to find themselves on opposite sides about important political issues. Many recognize social media as part of the problem, but how are these powerful customized advertising techniques contributing to the divisive landscape?
One important part is that people associated with foreign governments, without admitting that, take extreme positions in social media posts with the deliberate goal of sparking division and conflict. These extreme posts take advantage of the social media algorithms (算法), which are designed to heighten engagement Meanwhile, people seeking to influence others put things to more and more extreme positions. The result is apparent. Rather than most people having balanced views with fewer people holding extreme views, fewer and fewer people are in the middle.
What can be done? Skepticism about social media recommendations matters. Keep on a more deliberate path to information and avoid just clicking on whatever is recommended. Second, consider supporting efforts to require social media platforms to offer users a choice of algorithms for recommendations. Most importantly, invest more time in interacting with friends and family off social media. Probably, you’ll be far off a constructed track toward extremes.

4 . Shyness is normal and it is not considered as a mental problem. All people have been shy at one time or another. Even the most confident people experienced being shy.
You probably are wondering why you are shy. It may be because of the environment you were used to or the way you were brought up. Certain events or incidents in the past may also lead to the reason why you are shy now.
One of the negative sides of being shy is having the tendency to be passive. Most of the time shy people can’t stand up for themselves and what they believe is right.
While shyness has negative aspects, it has positive sides. Shy people are usually good observers and do not get themselves into too much trouble because they try to observe their environment or any situation before they act.
| A．But in most cases, shyness proves to be genetic. |
| B．They are sensitive and accustomed to getting suspicious. |
| C．Because some people are born to be shy, they let it go hang. |
| D．So if you’re feeling shy, don’t worry because you are not alone. |
| E．They are not hot-headed and think twice before making any decisions. |
| F．Although shyness is something from birth, it can be improved over time. |
| G．They avoid crowds by nature and stay away from groups and social interactions. |
5 . The coronavirus has been a catalyst for change in many areas of our lives. As things return to normal, one thing that is likely to remain for many is the practice of working from home, known as telecommuting.
Much like the cloud classroom, the cloud office enables employees to cooperate, access resources and operate software from any location. Without doubt, communication tools play an important role. Video and voice chat allow a team, regardless of location, to work together as if they're in the same office.
The rise of telecommuting is due in part to time-tracking applications and software that allows employers to monitor productivity. Wechat Work and Work Examiner are all popular options that have been adopted by thousands of companies. These tools make employers feel secure that remote workers are staying on task. As an increasingly popular approach to work, the objective of the cloud office is to find the ideal balance between home and office work.
According to CNBC, a study showed that 85 percent of millennials（千禧一代）preferred working from home as it gives them a healthier work-life balance, flexible hours and more autonomy. It also showed that firms could save $ 11,000per person each year by allowing employees to work from home.
However, not everyone sees this revolution as positive. According to Bloomberg, in a survey of 1,001 US workers, 45 percent felt burnt out due to the increased workload, decreased communication and the requirement to juggle（兼顾）professional and personal life.
There has indeed been a mixed reaction to the move amid the pandemic.
It's believed that it will become more manageable once lockdown measures are fully lifted worldwide. And by then, who knows what tasks we could all achieve from the comfort of our sofas?

7 . In 2019, more than 1. 4 million young people around the globe took part in the School Strikes for Climate Action protests that were largely prompted by a 17-year-old Swedish activist Greta Thunberg. The inspirational teenage is far from the first or last young person to fight for a better environmental future.
With the rise of social media in recent years, young people around the globe have easy access to surprising information about how we're currently failing to look after the Earth. Websites such as YouTube provide accessible coverage on ecological matters and links to new scientific information are easily shared between peers. But, it's not just online research that exposes the truth, and it's not a distant threat either. Climate change is around us. Our oceans are 30 percent more acidic(酸性的)due to carbon pollution, an increase of droughts and heatwaves means a loss of crop production and forest is cut down every second.
Of course, just because young people are now readily armed with statistics doesn't mean all adults will eagerly listen to them. Many write off young activists simply due to their age, and others still aren't willing to see the environmental challenges we face, but that doesn't mean a diligence can’t be made.
In fact, there are some advantages of being a young activist. A study on participants aged 16-24 in the UN climate negotiations revealed that adults perceived younger activists as being more trustworthy. Young activists not only aren't smudged (弄脏)by agendas being forced on them, they also have an untainted(未染污的)view of what's going on and, being free from politics, they often say what adults aren't willing to.
So, it seems achieving a carbon neutral world in the future might depend on young determined voices inspiring experienced adults who can make a difference. Preferably, young people wouldn't worry about the environment at all, but our civilization forced them into the conversation when their futures were put at stake, so their voices should be included in the solution.
1. What is the second paragraph mainly about?| A．The influence of social media. |
| B．The truth behind the statistics. |
| C．The different examples of Climate change effects. |
| D．Young people's easy exposure to climate problems. |
| A．Adults speak highly of the young people. |
| B．Adults look down upon the young people. |
| C．Adults show sympathy to the young people. |
| D．Adults regard young people as unimportant persons. |
| A．Taking a younger approach. | B．Protecting the globe. |
| C．Speaking out your voices. | D．Meeting environmental challenges. |
8 . At one point in June last year, Zeng Jiapeng was more than 10,000 yuan in debt to a smart phone app. The 23-year-old Shanghai citizen pays for his online purchases of food, clothes, and travel with Huabei, a virtual credit card that's part of Alibaba Group Holding Ltd.’s spreading stable of e-commerce. His spending often used to go beyond his only source of income: the 8,000-yuan monthly allowance from his parents. He tried to repay the debt in installments(分期), even borrowing from Jiebei, another Alibaba-owned credit service, but eventually his mother and father had to help him out.
Zeng’s story is typical of members of China’ Generation Z. These young consumers, born from the mid-1990s to the early 2000s, have little income and therefore actually no credit history. Yet they have easy access to credit from an assortment of banks, financial-tech companies, and peer-to-peer (P2P) Lenders(网络借贷平台), plus other channels that are unregulated. The spending habits of the young in particular are causing concern. In some cases the younger generation is being tempted to overconsume via credit secured through technology. Unsecured consumer lending has expanded 20% a year in China since 2008. The amount of consumer finance available through the Internet will more than double, to 19 trillion yuan, by 2021, from 7.8 trillion yuan last year. Official data showed that almost 70% of China’s 50 million P2P borrowers were younger than 40.
As for Zeng, he’s trying to be a little more frugal, even though he is now trying to earn a little by himself. “I deliberately set the credit limit at a lower level,” he says, “so that hopefully I can better match my income with spending.”
Regulators(监管部门)last year launched a breakdown on peer-to-peer lending, which, besides being a source of easy credit, had also become a popular investment vehicle. The sector has shrunk to less than half its peak size as a result of forced shutdowns.
1. What can we learn about Zeng Jiapeng from the first paragraph?| A．He was in debt because he bought smart phone app. |
| B．He likes purchasing goods on the app Huabei of Alibaba Group. |
| C．He always spent more than he earned from his salary in the past. |
| D．He depended on his parents to support him to repay his debt. |
| A．Impractical | B．Hardworking |
| C．Avoiding waste | D．Relying on others |
| A．Overconsumption-A Bad Habit | B．China’s Generation Z-Hooked On Credit |
| C．Chinese Youth In the E-commerce Age | D．Zeng Jinpeng’s Financial Crisis |
9 . Tam the aunt, granddaughter, daughter ,and sister of Baptist ministers. Service was as essential a part of my upbringing as eating and sleeping and going to school. The church was a center of Black children's social existence,and Black adults were buffers(缓冲）against the segregated(种族隔离的）outside world that told us we weren't important. But our parents said it wasn't so.
We couldn't play in public playgrounds or sit at drugstore lunch counters and order a Coke, so Daddy built a playground and canteen behind the church. There were no Black homes for the aged in Bennettsville, so he began one across the street for which he and Mama and we children cooked and served. And we children learned that it was our responsibility to take care of elderly family members and neighbors.
We learned early what our parents and extended community “parents” valued. Children were
taught-not by teaching, but by personal example-that no kindness, however small, was ever wasted. I remember a debate my parents had when I was eight or nine as to whether I was too young to go to help clean the bed of a very sick, poor woman. I went and learned just how much the smallest helping hands could mean to a person in need.
The adults in our community made children feel valued and important. They struggled to find ways to keep us busy. And while life was often hard and resources scarce, we always knew who we were and that the measure of our worth was inside our heads and hearts. We were told that the world had a lot of problems, that Black people had an extra lot of problems, but that we ought to and were able to struggle and change them, that being poor was no excuse for not achieving, and that we had the responsibility of sharing with the less fortunate.
1. What does the underlined word "it" in paragraph 1 refer to?| A．Service was very important. |
| B．Church was where blacks could stay. |
| C．Blacks were not as important as others. |
| D．Black adults were protectors against the outside world. |
| A．To call on others to help the woman. |
| B．To prove children learn by personal example |
| C．To stress the influence of parents on children. |
| D．To indicate even the smallest good deed counts |
| A．they had to struggle and share |
| B．they had little chance of success |
| C．they were too young to help others. |
| D．they caused extra problems to the world |
10 . What is the nature of the scientific attitude, the attitude of the man or woman who studies and applies physics, biology, chemistry, geology, engineering, medicine or any other science?
We all know that science plays an important role in our societies. However, many people believe that our progress depends on two different aspects of science. The first aspect is the application of the machines, products and systems of knowledge that scientists and technologists develop. The second is the application of the special methods of thought and action that scientists use in their work.
What are these special methods of thinking and acting? First of all, it seems that a successful scientist is curious - he wants to find out how and why the universe works. He usually pays attention to problems which he notices have no satisfying explanation, and looks for relationships even if the data available seem to be unconnected. Moreover, he thinks he can improve the existing conditions and enjoys trying to solve the problems which this involves.
He is a good observer, accurate, patient and objective and uses the facts he observes to the fullest. For example, trained observers obtain a very large amount of information about a star mainly from the accurate analysis of the simple lines that appear in a spectrum(光谱).
He does not accept statements which are not based on the most complete evidence available. He rejects authority as the only basis for truth. Scientists always check statements and make experiments carefully and objectively.
Furthermore, he does not readily accept his own idea, since he knows that man is the least reliable of scientific instruments and that a number of factors tend to disturb objective investigation.
Lastly, he is full of imagination since he often has to look for relationships in data which are not only complex but also frequently incomplete. Furthermore, he needs imagination if he wants to guess how processes work and how events take place.
These seem to be some of the ways in which a successful scientist or technologist thinks and acts.
1. Which of the following statements about a curious scientist is TRUE?| A．He doesn't find confidence and pleasure in work. |
| B．He makes efforts to investigate potential connections. |
| C．He is interested in problems that are explained. |
| D．He looks for new ways of acting. |
| A．easily appreciate others' research work |
| B．easily believe in unchecked statements |
| C．always accept authority as the only basis for truth |
| D．always use evidence from observation to the fullest |
| A．Objective and careful. | B．Curious and casual. |
| C．Cautious and arrogant. | D．Subjective and down-to-death . |
| A．Key to a successful scientist. | B．Scientists’ ways of thinking and acting |
| C．Progress in modern society. | D．Application of modern technology. |
