From the top of the Great Wall, people can enjoy 8. impressive view of continuous mountains, green trees and blooming wild flowers. If we were to build such a wall now, we would use modern machines. 9., the ancient Chinese had to build the wall by hand. The reason why the Great Wall attracts tourists from all over the world every year is 10. it represents the highest wisdom of ancient china. Just as the saying goes, “He who has never been to the Great Wall is not a true man.”

    It is sometimes thought that the longing for material goods, the need to buy things, is a relatively modern invention. 1. Trade or shopping is certainly an ancient desire, and existed before our ancestors invented writing, laws, cities or farming, even before they used metal to make tools.

Humans are born to trade. 2. Evidence from hunter-gatherers suggests that the exchange of food and other necessary things comes naturally, as well as the ability to keep a record of the credits involved. And once trade begins, the benefits are hard to resist.

Ancient local coastal people in northern Australia traded fish hooks, along a chain of trading partners, with people living 400 miles inland, who cut and polished local stone to make axes (斧子). 3. Finally, both groups of “producers”, by concentrating on things they could produce and exchanging them for other things they needed, benefited as a result.

Trade in the necessities of life, such as food and simple tools, is not really surprising, considering the link between these basic items and survival. What is surprising, though, is that our taste for unnecessary expensive objects also goes back a long way.

In South Africa, 100,000-year-old decorative dyes (染料) have been found in an area where none were produced. 4. Small round pieces of glass 76,000 years old were also found at the same place. The earliest jewellery known to us were not just random findings — they were grouped together in size and had holes like those used for threading onto a necklace.

Archaeologists argue that trade prepared the way for the complex societies in which we live today. 5. However, their modern equivalents — fast cars and expensive clothes — hold the same attraction for us as “trade goods” did for people 100,000 years ago.

A.And we don’t need shops or money to do it.

B.These are powerful evidence for cash purchase.

C.In fact, its roots go back to the beginning of humanity.

D.However, first trade began from the exchange of objects.

E.Modern-day shoppers may not be impressed by ancient glass pieces.

F.It is thought that these goods were bought at least 30  kilometres  away.

G.Every individual along the chain made a profit, even if he produced neither himself.

    If you wear glasses, chances are you are smarter. Research published in the famous British journal Nature Communications has found that people who displayed higher levels of intelligence were almost 30 percent more likely to wear glasses.

The scientists studied the genes of thousands of people between the ages of 16 and 102.The study showed intelligence can be connected to physical characteristics. One characteristic was eyesight. In out of 10 people who were more intelligent, there was a higher chance they needed glasses. Scientists also said being smarter has other benefits. It is connected to better health.

It is important to remember these are connections which are not proven causes. Scientists call this correlation. Just because something is connected to something else does not mean one of those things caused the other. And it’s worth noting that what constitutes intelligence is subjective and can be difficult, if not impossible, to measure.

Forget genes though. Plenty of proof shows wearing glasses makes people think you are more intelligent, even if you do not need glasses. A number of studies have found people who wear glasses are seen as smarter, hard-working and honest. Many lawyers use this idea to help win their cases. Lawyer Harvey Solves explained this. Glasses soften their appearance. He said Sometimes there has been a huge amount of proof showing that people he was defending broke the law. He had them wear glasses and they weren’t found guilty.

Glasses are also used to show someone is intelligent in movies and on TV. Ideas about people who wear glasses have begun to shift. People who do not need glasses sometimes wear them for fashion only. They want to look worldly or cool. But not everyone is impressed by this idea, though. GQ magazine said people who wear glasses for fashion are trying too hard to look smart and hip (时髦的). However, that hasn’t stopped many celebrities from happily wearing glasses even if they do not need them. Justin Bieber is just one high-profile fan of fashion glasses.

1.What does the new study show?

A.People wearing glasses are smarter.

B.People wearing glasses are healthier.

C.Wearing glasses can make people cleverer.

D.Wearing glasses is associated with higher IQ.

2.What does the underlined word in Paragraph 3 mean?

A.Shift. B.Link. C.Proof. D.Consequence.

3.Why do some lawyers ask their clients to wear glasses in court?

A.Because it can create a moral image.

B.Because it can mislead the witnesses.

C.Because it can highlight clients’ qualities.

D.Because it can prove the clients’ innocence.

4.What is the general attitude to those who wear glasses for fashion?

A.Positive. B.Negative. C.Mixed D.Indifferent.

    A video of a three-year-old girl being kicked by her own mother during a photo shot went viral on Thursday, indicating China’s underperformance in regulating the emerging child modeling industry.

The girl, known as Niu Niu, was physically abused (虐待) by her mother in several videos. The videos have annoyed Chinese media and Internet users alike. Many netizens and scholars call for local authorities to carry out further investigations into possible child abuse.

In response to the public outcry (强烈抗议), Niu Niu’s mother issued an apology via Sina Weibo on Thursday, condemning accusations of abuse. She noted that she was merely guiding her daughter for better shots and the girl is well looked after.

Despite her apology, many E-shops which used Niu Niu’s images for brand promotion have canceled their cooperation with the mother, while over 110 well-known child garment shops on Taobao have signed up for a campaign to provide better protection for child models.

“It is necessary to adopt comprehensive laws and regulations to further protect the kids, preventing their parents and companies from exploiting them,” Fang Zhiqing, a lawyer and child protection expert, said.

Niu Niu is not alone. In Zhili, a small town in Zhejiang province, thousands of children from across China are taken here by their parents to seize the chance of fame. With a population of 450,000, Zhili has over 13,000 manufacturers of child clothing. In 2017.the town earned over 7 billion yuan by selling clothing for children online, thus providing opportunities for child models.

“China’s current advertisement law isn’t workable with respect to the industry of child modeling, as it lacks clear regulatory measures and clear legal punishment.” Fang added, “It is important to issue new laws which regulate child modeling.”

1.What caused the public outcry?

A.A girl being physically abused by her mother.

B.Problems in Chinese advertising industry.

C.Several cases of child abuse in recent China.

D.Videos showing how child models work.

2.What happened after the public outcry?

A.Local authorities have thoroughly looked into Niu Niu’s case.

B.Niu Niu’s mother admitted abusing her daughter.

C.Shops stopped their cooperation with the mother.

D.The online sales of child clothing are increasing.

3.Which opinion may Fang Zhiqing agree with?

A.China’s current advertisement law isn’t workable.

B.There are too many child models in China.

C.New economic laws should be issued in China.

D.China should regulate child modeling.

    Darrell Blatchley, a marine biologist and environmentalist based in the Philippine city of Davao, received a call from the philippines’ Bureau of Fisheries and Aquatic Resources (渔业与水产资源局) early Friday morning reporting a death of a young whale.

When the necropsy (尸检) was performed, Blatchley told NPR, he was not prepared for the amount of plastic they found in the whale’s stomach. “It was full of plastic- nothing but nonstop plastic,” he said. “It was filled to the point that its stomach was as hard as a baseball.” “That means that this animal has been suffering not for days or weeks but for months or even a year or more.” Blatchley added.

Blatchley is the founder and owner of the D’ Bone Collector Museum, a natural history museum in Davao. In the coming days, the museum will display all the items found in the whale’s system.

Blatchley and his team work with the Bureau of Fisheries and Aquatic Resources and other organizations to assist in rescue and recovery of marine animals.

“Within the last 10 years, we have recovered 61 whales and dolphins just within the Davao Gulf,” he said. “Of them, 57 have died due to man --whether they took plastic or fishing nets or other waste, or gotten caught in pollution-- and four were pregnant.”

Blatchley said he hoped that the latest incident would launch the issue of plastic pollution in the Philippines and across the globe. “If we keep going this way, it will be more uncommon to see an animal die of natural causes than it is to see an animal die of plastic.” he said.

1.What can be inferred from the second paragraph?

A.The whale was starved to death.

B.Blatchley didn’t make preparations for the necropsy.

C.The dead whale must have swallowed a baseball.

D.Blatchley was shocked at what he found.

2.What does Blatchley think of plastic pollution in the Philippines?

A.Uncommon. B.Inspiring.

C.Worrying. D.Puzzling.

3.What is the best title for the text?

A.Natural Death or Merciless murder.

B.Stand Up for Protecting Whales.

C.Plastic Threatening Our Existence.

D.A Whale Found Dead of Plastic.

Teenagers are especially likely to suffer loneliness. Here are some suggestions for speeding a recovery from loneliness.

Reach out to others, but start small. A smile and a friendly greeting for the student behind you in line at the cafeteria won’t make you best friends.1.It also can make it easier to interact the next time.

Find a safe place to make connections. If going to the school dance makes you feel like you just don’t belong, try joining a special-interest group. Maybe it’s the drama club or the marching band. 2..

Find other ways of making connections. Lonely people hunger for acceptance and friendship. Sometimes feeling accepted and liked comes more easily when you do something for others.3.Teach a child in reading. Take notes for a disabled classmate. You might be surprised at the connections you make after reaching out in these ways.

4.Loneliness is an absence of quality friendships, not of a particular quantity of friends. That’s why it’s important to know how to select a friend. The best friendships are those based on similar values and attitudes.

You get what you expect, so expect the best. If you expect others to be friendly, you will behave in similar ways.5.It goes away as teens learn how to find their way through their social world and connect with others.

A.But it will make you both feel pretty good.

B.So consider becoming a volunteer.

C.Some teens aren’t so adaptable, however.

D.Encourage people to be friendlier to you.

E.Choose the right people.

F.For most young people, loneliness is only temporary.

G.Look for a group that allows you to ease in gradually.

    Wind farms have been considered as the way to fight global warming, but a new study suggests they could actually heat the planet up.

The study found that the US would get warmer if the number of turbines(涡轮机）were increased markedly. Researchers say they'll require much more land than previously thought, needing five to 20 times more space than earlier studies have suggested. And winds created by vast fields of turbines could mix warm and cool air, which makes the surface quite warm .

Despite the potential drawbacks, however, the researchers argue wind energy still makes more sense for the environment than fossil fuels. Study coauthor and Harvard University scientist Professor David Keith argued that, when it comes to energy production, there is no free lunch. "Wind beats coal by any environmental measure, but that doesn't mean that its effects can be ignored. We must use fewer fossil fuels to stop carbon production. In doing so, we must make choices between various low-carbon technologies , all of which have some environmental effects , " he said.

More than ten previous studies have now observed local warming caused by US wind farms. Researchers suggested that solar power offers a less damaging energy source in the fight against climate change. In terms of temperature difference per unit of energy generation, solar power has about 10 times less effect than wind, and the solar power energy is mature in a wide range of fields. But there are other considerations. For example, solar farms are dense(密集的）, while the land between wind turbines can be co-used for agriculture.

Tidal power is an environmentally-friendly energy source. In addition to being a renewable energy, it does not give off any climate gases and does not take up a lot of space . However , there are currently very few examples from real tidal power plants and their effects on the environment. Also, it is important to realize that the methods for generating electricity from tidal energy are relatively new technologies. It is projected that tidal power will be commercially profitable within2030 with better technology and larger scales.

1.What is the purpose of the text?

A.To introduce a study finding.

B.To discuss the global warming problem.

C.To prove the benefits of wind farms.

D.To call attention to environmental protection.

2.What is paragraph 2 mainly about ?

A.The effects of global warming.

B.The reason for using wind energy.

C.The disadvantages of wind farms.

D.The working principle of wind farms.

3.What do Professor David Keith's words suggest?

A.Producing energy is easier than before.

B.Consuming energy damages the environment.

C.Burning coal should be totally stopped.

D.Developing low-carbon technologies is hard.

4.Which is recommended considering the environment and practical use?

A.Wind energy. B.Fossil fuel.

C.Tidal power. D.Solar energy.

    We humans love to stare into our smart devices. We gaze for hours-about 10 hours and 39 minutes a day-at our computers, smartphones,tablets and televisions. Is all this staring bad for us? It might be mainly because as we stare at our devices we are exposing ourselves to blue light.

Blue light is a type of electromagnetic(电磁的) radiation with a very short wavelength that produces a high amount of energy. While it’s true that light can damage our eyes under certain circumstances, there’s no scientific evidence suggesting that blue light is harmful to our eyes. But many people still think it is, which is why blue-light-blocking glasses are so popular. So do the glasses work?

“Everyone is very concerned that blue light may be causing damage to the eye, but there’s no evidence that it may be causing serious damage,” Dr. Rahul Khurana, clinical spokesman for the American Academy of Ophthalmology,told Business Insider.

Blue light exposure is nothing new. In fact,the sun is the largest source of blue light. Moreover, blue light is also present in LED light. But if blue light isn’t harmful, then why are we constantly rubbing our eyes when we’re looking at our screens? The answer is eyestrain(眼疲劳): More than 60 percent of people experience eye problems associated with digital eyestrain. And blue light, it seems, isn’t the cause. Instead, our eyes are so strained because most of us blink less when we stare at our digital devices. So if eyestrain is the issue, blue-light-blocking glasses are probably of little use.

1.What do we know about blue light?

A.It is a kind of nuclear radiation.

B.It has the shortest wavelength.

C.It may come from electronic devices.

D.It consumes a great deal of energy.

2.What causes the popularity of blue-light-blocking glasses?

A.Evidence of their benefits to eyes.

B.Belief in blue light's harmful effect.

C.Widespread use of smart devices.

D.Scientific understanding of blue light.

3.What can be inferred from Paragraph 4?

A.Blue light exposure is hardly avoidable.

B.Eye problems are not easy to deal with.

C.Blue light may connect with tired eyes.

D.Rubbing eyes makes people strained.

4.According to the text, wearing blue-light-blocking glasses may be________.

A.tiring B.harmful

C.useless D.beneficial

    Thirteen-year-old Madison Williams was studying in her bedroom when Leigh Williams, her mother, told her that a little boy fell into a septic tank(化粪池）and no one could reach him.

Madison and Leigh ran to a neighbor's yard, where they found the boy's worried mother and other adults surrounding the tank opening. It stuck out a few inches above the ground and was 11 inches in width-slightly wider than a basketball-with a hatch(盖子)that had been moved unnoticed. The two-year-old boy had slipped in and was drowning in four feet of waste water inside the eight-feet-deep tank.

Madison surveyed the situation. She was the only one who could fit through the small hole. Without hesitation, she told the adults, "Lower me in. Inside, the tank was dark, and the air was smelly . In the process , she jammed her left wrist against a hidden pole , injuring the muscles in her wrist so severely that the hand was left useless.

Rather than tending to her injury ,Madison tried to feel the underwater boy. Minutes went by before she saw the outline of his foot. Madison shot her good hand out and grasped the foot tightly "Pull me up!" she shouted. Then, ten minutes after Madison had entered the tank, she and the boy were lifted out.

But the boy wasn't out of trouble. He had lacked Oxygen long enough that he wasn't breathing. He was placed on his side, and an adult hit him hard on the back. It was only when Madison heard him cry that she knew he was all right . It took Madison longer to recover than the boy, who was taken to hospital and left hospital that same night .She, however, experienced months of painful treatment, for the injury that she had postponed tending was more severe, which, says neighbor Mary Holley, made the girl's actions all the more impressive.

1.What most likely caused the boy to fall into the septic tank?

A.The tank was very hard to be noticed.

B.The boy was curious about the unknown.

C.The hatch was not in the correct position.

D.The tank opening stood out on the ground.

2.Why did Madison take longer to recover?

A.The injury to her wrist became worse

B.She wasn't sent to hospital in time.

C.She paid all her attention to the boy.

D.Serious infection set in to her wound.

3.Which of the following can be used to best describe Madison?

A.Modest. B.Optimistic.

C.Courageous. D.Hard-working.

4.What is the text mainly about?

A.A lucky little boy. B.A terrible drowning accident.

Teenagers are just the sort of people an online seller is interested in, and the things they want to buy — games, CDs and clothing — are easily sold on the Web.

But paying online is a tricky business for consumers who are too young to own credit cards. Most have to use a parents card. They want a facility that allows them to spend money.

That may come sooner than they think: new ways to take pocket money into cyber space are coming out rapidly on both sides of the Atlantic. If successful, these products could stimulate online sales.

In general, teenagers spend huge amounts: $153 bn (billion) in the US last year and £20 bn annually in the UK. Most teenagers have access to the Internet at home or at school — 88 percent in the US, 69 percent in the UK. According to Jupiter Research, one in eight of those with Internet access has bought something online — mainly CDs and books.

In most cases, parents pay for these purchases with credit cards, an arrangement that is often unsatisfactory for them and their children. Pressing parents to spend online is less productive than pressing on the high street. They’re more likely to ask “Why” if you ask to spend some money online.

One way to help teenagers change notes and coins into cybercash is through prepaid cards such as IntenetCash in the US and Smart cards in the UK, Similar to those for pay-as-you-go mobile telephones, they are sold in amounts such as £20 or $50 with a concealed 14-digit number that can be used to load the cash into an online account.

Directions: Read the following passage. Fill in each blank with a proper sentence given in the box. Each sentence can be used only once. Note that there are two more sentences than you need.

There are two kinds of motive for engaging in any activity: internal and instrumental. If a scientist conducts research because he wants to discover important facts about the world, internal motive. If he conducts research because he wants to achieve scholarly fame, that’s an instrumental motive. 1..

What mix of motives — internal or instrumental or both — is most favorable to success? You might suppose that a scientist motivated by a desire to discover facts and by a desire to achieve fame will do better work than a scientist motivated by just one of those desires. 2.But as we and our colleagues argue in a paper, instrumental motives are not always useful and can actually be counterproductive to success.

3.Helping people focus on the meaning and impact of their work, rather than on, say, the financial returns it will bring, may be the best way to improve not only the quality of their work but also their financial success.

There is a temptation among educators and instructors to use whatever motivational tools are available to recruit (招募) participants or improve performance. If the desire for military excellence and service to country fails to attract all the recruits that the Army needs, then perhaps appeals to “money for college,” “career training” or “seeing the world” will do the job.

4.Similarly, for students uninterested in learning, financial incentives (奖励) for good attendance or pizza parties for high performance may motivate them to participate, but it may result in less well-educated students.

A.Our study suggests that efforts should be made to structure activities so that instrumental consequences do not become motives.

B.That’s the secret of effective motivation.

C.While this strategy may attract more recruits, it may also produce worse soldiers.

D.Surely two motives are better than one.

E.Discovering facts is inseparably related to the activity of research.

F.Often, people have both internal and instrumental motives for doing what they do.

    Before Douglas Engelbart, computers were as big as rooms and used mostly for handling numbers. But in the late ‘60s’at the Stanford Research Institute, Engelbart invented almost everything your personal computer has today: a mouse, hypertext, screen sharing and more. In 1968 he made real-time edits to documents nearly 40 years before Google Docs hit screens; video chatted with friends long before Skype’s 2003 arrival; and resized windows years before Microsoft entered the field in 1975. Engelbart was adding graphics (图形), hyperlinking and sharing screens — all before the birth of the World Wide Web. “The digital revolution is far more significant than the invention of writing or even of printing,” said Engelbart, and as it turns out, he held all the right cards.

If he’d been British，Engelbart would have been knighted (授爵), but the Portland, Oregon, native instead lived out the rest of his years as an unsung hero, trying to fry even bigger fish in Silicon Valley. His blueprint of the Internet was radically different from today’s profit- driven, streamlined version. Engelbart imagined an information system built on the backbones of cooperation and education, all meant to enhance the collective human mind. He wanted a computerized network of real-time, human-wide cooperation, with the open-source spirit of Wikipedia and the purposefulness of Change.org.

By the late 70s and early ‘80s’ Engelbart and his ideas were cast aside in favor of Apple Macintosh and Microsoft Windows, along with their profit-generating vision for personal computing, and a user-friendly approach to the Internet. Engelbart’s team of researchers abandoned him, and he had a lesser position at a company called Tymshare while still battling with his pie-in-the-sky visions of a better world. Even worse, when Engelbart’s mouse invention gained widespread use years later, he never gained the profits — it had been licensed to Apple for around $40,000, Engelbart revealed.

And if Engelbart had won? “Hard to say,” says Jefferson Bailey of the Internet Archive in San Francisco. The Web was bound to grow in ways its founders never intended, he says. He notes his belief that the same spirit of knowledge-sharing and cooperation Engelbart tirelessly pushed for will one day become part of our fast-evolving Internet, even if a commercial layer clouds the original vision. But even so，fame is difficult to achieve; it often ridicules great thinkers like Galileo or Tesla, only to meet them decades after death. Granted, Engelbart was eventually allowed into the National Inventors Hall of Fame, in 1988, and into the Pioneers Circle in the Internet Hall of Fame after his death, but the heart of his dream has yet to be realized.

D.an Internet of knowledge-sharing and cooperation

2.Most probably Engelbart’s greatest regret was that___________________.

3.Which of the following is NOT true according to the passage?

A.Engelbart rose and fell in his all-out battle over the future of the Internet.

B.Engelbart could have succeeded in the Internet with his landmark inventions.

    Northern Virginia Community College had agreed to stop awarding scholarships based on race.

The college took that step, Virginia’s Attorney (司法局) said last week, after the U.S. Education Department’s Office for Civil Rights had concluded that the privately financed scholarship programs for minority students did not follow established federal (联邦的) guidelines for such programs.

The civil-rights office got involved when a white student at Northern Virginia complained in June 1996 that he had been illegally excluded from a scholarship program for minority students.

Christopher Thompson argued in his complaint that such programs had been found unconstitutional ― (不符合法规的) in 1994 by the U. S. Court of Appeals for the Fourth Circuit (联邦上诉法院第四管辖区), in a case involving a blacks-only scholarship at the University of Maryland at College Park.

In a letter to the department last month, the state Attorney Genera’s Office said the college would alter its five scholarship programs that have been limited to students of certain races. All of the programs were financed by private donors or groups.

“After careful consideration of the position taken by your office, in response to the complaint filed with the Office for Civil Rights by a student at the college, and the legal arguments presented to us by lawyers representing that student, the college has concluded that it will abandon its administration of race-based scholarships,” wrote Maureen Riley Masten, an Assistant Attorney General.

Northern Virginia officials said that two of the aid programs would be opened to students of all races, and that the sponsors of two others had asked that their money be returned. The sponsors of the fifth program said they would transfer the funds to a private, non-profit group that would continue to administer the scholarship to minority students only, the college said.

Officials of many colleges have watched the Northern Virginia case because they believed that it might throw new light on how the Education Department would view the legality of scholarship programs financed by private donors.

A spokesman for the department, Rodger Murphey, said he did not believe that a new precedent (判例) had been set in the case.

1.What was Christopher Thompson’s complaint?

A.He wasn’t qualified for his college’s race-based scholarships as a white student.

B.The lawyers refused to represent him in his appeal against his college’s decision.

C.Northern Virginia officials decided that his appeal to the state court was illegal.

D.The civil-rights office failed to respond to his complaint about his college.

2.What was the civil-rights office’s position in Christopher Thompsons case?

A.The college should justify its race-based scholarship programs.

B.The college should transfer its scholarship funds to non-profit groups.

C.The college should open its scholarship programs to students of all races.

D.The college should put aside its prejudice against white students.

3.How did Northern Virginia Community College respond to the civil-rights office’s decision?

A.It continued to administer its scholarship programs despite the complaint.

B.It got new sponsors to open scholarship programs to students of all races.

C.It stopped its scholarship programs temporarily to confirm their legality.

D.It abandoned its scholarship programs exclusively for minority students.

4.Which of the following can NOT be inferred from the passage?

A.Christopher Thompson based his complaint legally on the Maryland case.

B.The legality of privately financed scholarships was still uncertain.

C.Race-based scholarship programs would be presented in a new form.

D.The courts decision in the case would be followed in later similar cases.

    Most of the time, people are well aware of the circumstances of exchange: they exchange this for that. But in the rare circumstances when they’ve not prepared with gift-giving in return, they can be _________ with feelings of guilt. Receiving a gift, Jacques Derrida, a French thinker, thought, could make one feel like a _________ trapped in a cycle of economic exchange. People don’t like the feeling of being under obligation (人情债) , and try to dismiss the _________ they can feel as quickly as possible.

Private gift-giving, as the Frankfurt school theorist Theodor Adorno worried, has become an empty procedure. There’s no denying that in at least some cases, people give gifts _________. This has less to do with gift-giving itself, and more to do with the choosing of gifts. Gift-giving looks like an obligation, and a fairly _________one at that. Sure, there is giving gifts to lovers, friends and family. But then there is also the world of gift-giving like Secret Santa Claus, practices that keep gift-giving routines going well _________ the circles of people we know well enough to make choosing presents _________.

For these forced occasions, for, say, the coworker we’ve never spoken to, there are pre-printed cards and commercial guides. Even when the receiver is well-known, people want to _________ the effort needed for gifting. A relative once sent me a gift basket of dried fruit, nuts and cured meats; both the offending party and I are vegetarians.

If gift-giving has become more transaction (交易的), with the give-and-take a(n) _________ itself, so has complimenting.

This ____________ choice — fulfill your obligation to return the ____________ or resign yourself to guilt — comes from belonging to a society structured around commodities and their ____________.The trouble is, if compliments are transactions, feeling that we’re under obligation is a natural state of affairs. To imagine that we could completely overcome our ways of thinking about compliments, ____________, requires ____________ our social and economic forms of life. ____________ a difficult demand, this could be the true gift Adorno and Derrida were hoping for.

I teach a course in marine biology at a college in central Maine. In order to give each student the individualized attention he or she 1.(deserve), I cap the class size at 15. Some years back, while calling out names from the roster (花名册) on the first day, I noticed a gray-haired woman of about 70. She 2.(hang) about at the door, with her new books like a schoolgirl.

“I’m not on the roster,” she volunteered, clearly self-conscious about all the 3.(seat) 18-year-olds looking her over. “But I was wondering if I 4.just sit in on the first class, to see what it’s about.”

There were already 15 in the class, but this woman’s eagerness impressed me, so I invited her to have a seat.

I began by chatting informally with the class to get a feel for how much knowledge they were bringing to 5.course. The result of open admissions is that professors are faced with very uneven crops of students, many of 6. know relatively little about the world around them.

In marine biology I like to see if they know the difference between fishes and seagoing mammals (哺乳动物). I often hold up a sponge (海绵) in the hope 7. someone will recognize it as an animal rather than a plant. I talk about the difference between a sea and an ocean.

8. I questioned, most of my new students remained silent. But Natalie, the older woman, was on the edge of her seat, 9.(volunteer) answers with the quickness of a game show contestant. In time, I felt as if it were just she and I engaged in a private conversation. At the end of class, she came up to me and apologized for being the “extra” student. “I certainly wish I could take this course,’’ she said. “Will you offer it next week?” Alarmed at the prospect of losing her, I acted quickly to relieve 10.concern. “I’ll see you next class,” I said.

When I finished all of my exam, my family drove to the countryside for a holiday. On our way, my favorite scarf flew out of the window suddenly and is gone. I felt very sad, regretting that when I hadn’t kept the scarf well. Soon after, we stopped at a service station. Feel upset, I found a bench and was about to ate my sandwich when a motorcyclist pulled into the station, “Is that your blue car?” he asked me. Although I felt surprising, I nodded quickly. A man pulled out the very scarf from my backpack and handed it to me. He then returned his motorcycle and wanted to leave. I went up and repaid him thankful by giving him a hug.

Some people will say “Open your gift!” immediately upon giving you a brightly 1. (wrap) box. Some of us are happy to help tearing off the paper with much 2. (excite). Others, however, experience anxiety when presented with a present. “What if I won’t like it?” they think. “What if it’s 3. (embarrass)?” Such questions can 4. (serious) stress a person out even if it isn’t obvious to the excited gift-giver.

Sometimes, 5. is necessary to bite the bullet even if gift-opening is uncomfortable for you, for instance if you’re the guest of honor at a bridal or baby shower. “In those situations 6. the opening of the gift is an activity of the event itself, go 7. it,” says Canada’s Etiquette Guy Jay Remer. “People who are attending the event expect that whatever gift they give is likely to be opened. It’s part of the fun.” So, if you refuse to open 8. (gift), the attendees (出席者), who give presents to you, might think you do not care about their blessings.

Etiquette expert Jacqueline Whitmore 9. (tend) to put the decision into the gift-giver’s hands. “Whenever I 10. (present) with a gift, I usually say ‘Shall I open it now?’ If the giver says ‘That’s up to you.’ I go ahead and open it because if I present someone with a gift, I want him to open it so I can see the happiness on his face.”

    Imagine that a close friend ignores you when you arrive at his party. 1. But if you think about the situation differently, you would calm down. Using a particular emotion management strategy called reappraisal, which involves viewing an upsetting event in a positive light, is often effective in contributing to positive outcomes.

2. The research showed that if people believed feelings were malleable (可塑造的), they used reappraisal more frequently, and in return they had greater emotional health and life satisfaction.

University of Toronto researcher Brett Ford and her colleagues did another study. 3. The researchers found that the youths who believed emotions were controllable used reappraisal more and were less depressed than those who didn’t.

Does accepting our feelings impact our well-being? 4. In one research, the researchers stressed out participants by requiring them to give an impromptu (即兴的) talk. In another research, people kept daily diaries about how they handled stressors (紧张性刺激). In both cases participants who accepted their feelings experienced less negative emotions than people who judged their feelings.

“However, while emotions may be changed with efforts, that doesn’t mean they’re completely controllable,” says Eric Smith of Stanford University, “we shouldn’t expect to completely avoid or immediately remove certain of feelings. 5.”

A.It found a similar pattern.

B.You would be angry or upset, right?

C.We have beliefs about our emotions.

D.According to Ford and her colleagues, it does.

E.But we can learn to reduce them in hard times.

F.They were also less depressed and more satisfied with life.

G.Now, new research suggests our beliefs about our feelings affect us greatly.

    People often think that blue light before bedtime can make it harder to sleep. It’s true that the screens on phones, computers and televisions send out plenty of blue light. But if you’re focused on blue light as a major problem affecting your sleep or your eye health, it’s time to look at it from another aspect.

As Philip Yuhas, a professor of vision, writes at The Conversation, blue light isn’t a uniquely technological evil. It’s part of sunlight, and your eyes are exposed to plenty of it all the time. You’re fine. There are studies in mice that have found blue light can damage their eyes, but mice are nocturnal creatures (夜行动物) whose eyes are different from ours. The pigments (色素) and the lenses (晶状体) of our eyes actually block blue light fairly well—so in a sense, we already have built-in blue blocking protection.

Adding more protection isn’t likely to help, though. You can buy glasses and screen filters (滤光片) that block blue light, but Yuhas points out they are probably a waste of money. These products do not block out much blue light. The leading blue-blocking anti-reflective coating, for example, blocks only about 15% of the blue light that screens send out. You could get the same reduction just by holding your phone another inch from your face.

The American Academy of Ophthalmology doesn’t recommend blue-blocking products, either. Instead, if you’re concerned about your eye health or your ability to get to sleep on time, you already know what to do.

Put the screens away at bedtime. Read a book or find something else to do. While you’re using screens, take a 20-second break every 20 minutes to look at something 20 feet away (the “20-20-20” rule). If you get dry eyes when you look at screens for a long time, use eye drops labeled artificial tears.

1.What do people often think of blue light?

A.It is magical and rare. B.It is the most part of sunlight.

C.It is harmful to people’s skin. D.It is a factor affecting peoples sleep.

2.What did the studies in paragraph 2 find?

A.Mice can see clearly in the dark.

B.Blue light can damage mice’s eyes.

C.Human eyes actually absorb blue light well.

D.Human eyes need extra protection against blue light.

3.What can we know about blue-blocking products according to Yuhas?

A.They block a little blue light.

B.People should buy a better one.

C.They are thought highly of by experts.

D.Most can prevent plenty of harmful lights.

4.What could be the best title for the text?

A.What will Blue Light Affect Actually?

B.Are Blue Light Really from Screens?

C.Does Blue Light Affect People’s Health?

D.Why Does Blue Light Make Sleeping Hard?
