In 2009 he moved again - to OI Pejeta Conservancy in Kenya, where it (22) _________ (hope) that the gentle giant would bread and ensure his species' survival. Elodie Sampere, a representative for OI Pejeta, described Sudan as "a gentle giant, his personality was just amazing and (23) _________ given his size, a lot of people were afraid of him, there was nothing mean about him."In 1960, about 2,000 northern white rhinos were estimated (24) _________ (move) about in Central Africa. However, years of fighting, habitat loss and poaching (illegal hunting and killing of wild animals) (25) _________ (drive) the northern white rhino to the very edge of extinction. Now, (26) _________ the passing of 45-year-old Sudan, there are just two northern white rhinos left in the whole world: his daughter, Najin, aged twenty-seven, and his granddaughter Fatu, who is seventeen. (27) _________ (live) in OI Pejeta Conservancy, they are well protected from poachers.The hope of preserving the northern white rhino now lies with scientists and (28) _________ ability to use Sudan's genetic material to artificially reproduce the animal.

Now we must stand up and demand action to prevent the same thing happening to cheetah, elephants, black rhinos and giraffes."Section BDirections: Fill in each blank with a proper word chosen from the box. Each word can only beThere are currently more than 500,000 pieces of space junk being tracked as they circle Earth. Space junk, or debris, consists of bits of metal, __31__ satellites and even a space station that is no longer in use, all of it circling the planet. Now this space station is about to fall to Earth.Tiangong-1 was China's first space station. It was __32__ in 2011, but the country lost contact with it in March 2016 and later that year, Chinese officials confirmed that the 3.5-metre-wide __33__ would return to Earth.At the moment, scientists don't know exactly where or when the space station will enter the planet's atmosphere, but believe it will be between 30 March and 2 April. There is no need to worry, though. While scientists can't say where it will land, there is very little __34__ that the space station will hit a populated area. This is because most of it will burn up in Earth's atmosphere - a(n) __35__ of gases that protect the planet. Also, because most of Earth is covered in water, scientists think that if there is any debris, it will fall __36__ into the sea.As the __37__ landing date gets closer, scientists will be able to determine where it will fall - if necessary - steps will be taken to keep people safe and __38__. A statement by Aerospace, a US company that advises the US government about space travel, said, "In the history of spaceflight, no known person has ever been harmed by __39__ space debris（残留物）."One thing scientists are confident of, though, is that wherever it enters the atmosphere, the debris will create a spectacular fireball for anyone __40__ enough to see it.III. Reading ComprehensionsSection ADirections: For each blank in the following passage, there are four words or phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.Governments are keen on higher education, seeing it as a means to boost social mobility and economic growth. Almost all sub-sidise（补贴）tuition - in America, to the tune of $200 billion a year. But they tend to overestimate the benefits and __41__ the costs of expanding university education. As more young people seek degrees, the returns both to them and to governments are __42__.Spending on universities is usually __43__ by the "graduate premium" - the increase in earnings that graduates enjoy over non-graduates. These individual gains, the thinking goes,__44__ an economic boost for society as a whole. But the graduate premium is a faulty unit of calculation. Part of the usefulness of a degree is that it gives a graduate job-seeker an advantage__45__ non-graduates. It is also a signal to employers of general qualities, such as intelligence and diligence, that someone already has in order to get into a university. Some professions require qualifications. But a degree is not always the best __46__ of the skills and knowledge needed for a job. With degrees so __47__, employers are using them as a way to screen applicants.Non-graduates are thus increasingly __48__ decent work.In any case, the premium counts only the winners and not the losers. Across the rich world, a third of university students never graduate. It is the weakest students who are drawn in as higher education __49__ and who are most likely to drop out. They pay fees and __50__ earnings to study, but see little improvement in their future incomes. When dropouts are __51__, the expected financial return to starting a degree for the weakest students shrinks to almost nothing. Many school-leavers are being __52__ about the probable value of university.Governments need to offer the young a wider range of options after school. They should start by rethinking their own __53__ practices. School-leavers should be given a wider variety of ways to gain vocation skills and to demonstrate their __54__. If school qualifications were made more difficult to get, employers would be more likely to trust them as signals of ability, and less __55__ degrees. "Micro-credentials" - short, work-focused courses approved by big employers infast-growing fields, such as IT - show promise.41. A. calculate B. cover C. ignore D. demonstrate42.

Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.(A)I wanted the pleasure of being in Africa again. Feeling that the place was so large it contained many untold tales and some hope and comedy and sweetness too, I aimed to reinsert myself in the bundy, as we used to call the bush, and to wander around. There I had lived and worked, happily, almost forty years ago, in the heart of the greenest continent.In those old undramatic days of my school teaching in the bundu, folks lived their lives on bush paths at the end of unpaved roads of red clay, in villages of grass-roofed huts. They had anew national flag, they had just gotten the vote, some had bikes, many talked about buying their first pair of shoes. They were hopeful, and so was I, a schoolteacher living near a settlement of mud-huts among trees and fields - children shouting at play; and women bent double - most with infants on their backs - hoeing（锄地）the corn beans; and the men sitting in the shade.The Swahili word safari means 'journey', it has nothing to do with animals, someone 'on safari' is just away and unobtainable and out of touch. Out of touch in Africa was where I wanted to be. The wish to disappear sends many travellers away. If you are thoroughly sick of being kept waiting at home or at work, travel is perfect: let other people wait for a change. Travel is a sort of revenge for having been put on hold, or having to leave messages on answering machines, not knowing your party's extension, being kept waiting all your working life. But also being kept waiting is the human condition.Travel in the African bush can also be a sort of revenge on mobile phones and email, on telephones and the daily paper, on the aspects of globalisation that allow anyone who chooses to get their hands on you. I desired to be unobtainable. I was going to Africa for the best of reasons - in a spirit of discover - simply to disappear, to light out, with a suggestion of I dare you to try to find me.Home had become a routine, and routine make time pass quickly. I was a sitting duck in this predictable routine: people knew when to call me, they knew when I would be at my desk. I was in such regular touch it was like having a job, a mode of life I hated .. I was sick of being called up and asked for favors, hit up for money. You stick around too long and people begin to impose their own deadlines on you.56. What did the writer expect from his journey?A. To have a variety of enjoyable experiences.B. To see how Africa had changed.C. To see impressive scenery.D. To meet some old friend.57. Forty years ago, how did the writer feel about the future of the country where he was living?A. Little was likely to change.B. Things were likely to improve.C. Women would do most of the work.D. People's expectations were too limited.58. In paragraph 3, what reason does the writer give for wanting to travel to Africa?A. He wanted a change of activity.B. He wanted people to be unable to contact him.C. His health was suffering from staying at home.D. He had been waiting to return to Africa for long.59. The writer says 'I was a sitting duck' in paragraph 5 to show that _________.A. he was boringB. he was easy to findC. he had a fixed lifestyleD. he was always lending money(B)The house style that dominated American housing during the 1880s and 1890s was known as Queen Anne, a curious name for an American style. The name was, in fact, a historical accident, originating with fashionable architects in Victorian England who coined it with apparently no reason other than its pleasing sound. The Queen Anne style was loosely based on structures built long before 1702, the beginning year of Queen Anne's reign（统治期）.A distinctive characteristic found in most Queen Anne houses is the unusual roof shape (illustrated in the picture on the right) - a steeply pitched, hipped central portion with protruding lower front and side extensions that end in gables. It is often possible to spot these distinctive roof forms from several blocks away. Another feature of this style is the detailing, shown in the wood board siding cut into fanciful decorative patterns of scallops, curves, diamonds, or triangles. Queen Anne houses are almost always asymmetrical（不对称的）. If you draw an imaginary line down the middle of one, you will see how different the right and left sides are, all the way from ground level to roof peak. A final characteristic is the inviting wraparound porch（门廊）that includes the front door area and then extends around to either the right or left side of the house.Queen Anne houses faded from fashion early in the twentieth century as the public's taste shifted toward the more modern Prairie and Craftsman style houses. Today, however, Queen Annehouses are favorite symbols of the past, painstakingly and lovingly restored by old-house buffs and reproduced by builders who give faithful attention to the distinctive shapes and detailing that were first popularized more than one hundred years ago.60. Why does the author use the word "curious" (in paragraph 1) in describing the name of an American style?A. The style was invented before Queen Anne's reign.B. The style was more popular in Victorian England.C. The name was accidentally misspelled.D. The name did not originate in America.61. Which of the following can be inferred from paragraph 2 about the Queen Anne style?A. It was not very popular.B. It had to be build in the city.C. It combined several other styles.D. It was elaborate and fancily decorated.62. According to passage, why did Queen Anne houses go out of style?A. People started moving to the suburbs.B. People came to see them as a symbol of the past.C. People were more interested in newer house styles.D. People could no longer afford to build such large houses.(C)What will the development of quantum computers（量子计算机）mean for our civilisations? Oh sure, better cryptography（密码方式）, "more powerful" processing, but bottom line, we just don't know ... yet.This phenomenon isn't unique to quantum computing, of course. It's something we see time and gain with all new world-changing technology. In some ways, it's how we can define a technology as world-changing: everyone agrees it's going to be hugely important, but nobody can predict exactly what impact it will have.The internet remains the classic example. Although invented in the 1960s, even by the late 1990s, the internet was still being dismissed as something that is fashionable but unlikely to last. Most commentators thought it nothing more than a curiosity.There's a famous 1999 interview between David Bowie and BBC journalist Jeremy Paxman. In it, Bowie predicts that the internet will change the nature of music, and remove the "barriers between creator and audience". The longer he spoke, the more Paxman said in anger that Bowie could possibly believe this about the internet.To be fair to Paxman, in 1999, internet at home meant accessing it over a modern. Concepts like WeChat and Netflix and more simply could not work over such limited bandwidth. But there were still some people who assumed that bandwidth would increase and that streaming music and video would be possible soon enough. They were laughed at.Oddly enough, as the dot-com boom intensified, many turned from doubters to hopeless optimists, and lost serious money building websites to deliver content that simply couldn't "fit" down the inter-tubes of the day.Then in the second decade of the 21st century: critical mass. Bandwidth increased massively. Forget showing a nice little video in your browser, today Nexflix can serve you a TV show in 4K, as long as you have 25Mbps connection.Quantum computing isn't a consumer technology, of course. It's a much bigger deal than that. Quantum computing is more like the invention of the transistor（电子晶体）. Sure, most people have heard of it, but few understand it. Actually, we don't even really understand it. But we're reasonably comfortable that when a lab has that many scanning electron microscopes, it must be doing something important, right?Quantum computing is still at the stage of "hit it with a hammer until it works". Sure the hammer is microscopic, and also a laser or magnetic field of some kind, but the point is we're going through the process of turning the idea into reality.Sooner than you think, though, qubit-based computers are going to get applied to stuff. What stuff? Like always, it will be super secret stuff first. Then it will reach the rest of us.This is how the world begins. Not with a bang, but with a lot of extremely hard work behind the scenes.63. What attitude did most people take towards the internet in the 1990s?A. Optimistic.B. Unconcerned.C. Doubtful.D. Defensive.64. The example of the internet is intended to illustrate that ________.A. it is hard to define what is world-changing technologyB. the internet was universally acknowledged as importantC. the influence of new technology is usually unpredictableD. the internet inspired many debates in the following years65. By "hit it with a hammer until it works", the writer means that quantum computing ________.A. has been questionedB. has been fully understoodC. hasn't been heard of beforeD. hasn't been applied to practice66. What can be concluded about new technology from the passage?A. Its development is a gradual process.B. Most is the brainchild of a scientist.C. Not all is accessible to the public.D. Its future is often a top secret.Section CDirections: Read the passage carefully. Fill in each blank with a proper sentence given in the box.The internet already enables patients to seek online consultations when and where it suits them. Yet change demands a shift in emphasis, from providers to patients and from doctors to data. ________67________ Technologies such as the smartphone allow people to monitor their own health. The possibilities multiply when you add the crucial missing ingredients - access to your own treatment and also to provide data to help train medical programmes.________68________ One is better diagnosis. Someone worried about their heart can now buy a watch strap containing a medical grade monitor that will detect arrhythmias（心律失常）. Apps are trying to see if they can diagnose everything from skin cancer to Parkinson's disease. Research is under way to see whether sweat can be analysed for molecular biomarkers without the need for an invasive blood test.A second benefit lies in the management of complex diseases. Diabetes（糖尿病）apps can change the way patients cope, by monitoring blood-glucose levels and food intake, potentially reducing long-run harm such as blindness. Akili Interactive, a startup, plans to seek regulatory approval for a video game designed to stimulate an area of the brain implicated in attention-deficit hyperactivity disorder.________69________ Although health records are increasingly electronic, many still contain data that machines cannot read. This can lead to delays in treatment, or worse. Many of the 250,000 death in America owed to medical error each year can be traced to poorly arranged care. ________70________ On January 24th Apple laid out its plans to ask organisations to let patients use their smartphones to download their own medical records.IV. Summary WritingDirections: Read the following three passages. Summarize the main idea and the main point(s) of the passage in no more than 60 words. Use your own words as far as possible.Change Is Needed In Youth SportsEverywhere you look, you see kids bouncing a basketball or waving a tennis bat. And these kids are getting younger and younger. Children can even compete on basketball, baseball, and volleyball teams starting at age nine. The youth soccer organization has teams for children asyoung as five. And swimming and gymnastics classes begin at age four, to prepare children for competition.It's true that a few of these kids will develop into highly skilled athletes and may even become members of our national Olympic teams. But what about the others - the average kids? This emphasis on competition in sports is having serious negative effects.Children who get involved in competitive sports at a young age often grow tired of their sport. Many parents pressure their kids to choose one sport and devote all their time to it. A survey found that 79 percent of parents of young athletes wanted their children to concentrate on one sport. But 66 percent of the young athletes wanted to play more than one sport - for fun.Another problem is the pressure imposed by over-competitive parents and coaches. Children are not naturally competitive. In fact, a recent study by Paulo David found that most children don't even understand the idea of competition until they are seven years old. Very young kids don't know why their parents are pushing them so hard.The third, the biggest, problem for young athletes is the lack of time to do their homework, have fun, be with friends - in short, time to be kids. When they are forced to spend every afternoon at sports practice, they often start to hate their chosen sport. Researchers found that 70 percent of kids who take part in competitive sports before the age of twelve quit before they turn eighteen. Many of them completely lose interest in sports. Excessive competition takes away all the enjoyment.V. TranslationDirections: Translate the following sentences into English, using the words given in the brackets.72. 对进口设备的禁令还未取消。

Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read. （A）They looked shocked and insulted and somehow ashamed. Above all, they looked old. Wexford thought that in the nature of things a woman of seventy ought to be an orphan, ought to have been an orphan for twenty years. This one had been an orphan for scarcely twenty days. Her husband sitting opposite her, pulling his thin moustache, slowly and mechanically shaking his head, seemed older than she, perhaps not so many years the junior of his late mother-in-law. He wore a brown knitted jacket and sheepskin slippers. His wife kept saying she couldn’t believe her ears, she couldn’tbelieve it, why were people so evil? Wexford didn’t answer that. He couldn’t, though he had often wondered himself.“My mother died of a stroke,” Mrs. Betts said nervously. “It was the death certificate. Dr. Moss put it on the death certificate.”“She was ninety-two,” Mr. Betts said in his thick throaty voice. “Ninety-two.”“I mean,” said Mrs. Betts, “Are you saying that Dr. Moss was telling untruth? A doctor?”“Why don’t you ask him? We’re only ordinary people, the wife and me, we’re not educated. Doctor said a cerebral hemorrhage (脑溢血),” Betts trembled a little over the words, “and in plain language that’s a stroke. That’s what he said. Are you saying the wife or me gave mother a stroke? Are you saying that?”“I’m making no claims, Mr. Betts.” Wexford felt uncomfortable, wished himself anywhere butin this newly decorated, paint-smartened house. “I’m merely making enquiries which information received obliges me to do.”“Gossip,” said Mr. Betts bitterly. “This street’s a hotbed of gossip. Pity they’re nothing betterto do. Oh, I know what they’re saying. Half of them turn up their noses and looked the other way when I pass them.”Mr. Betts stared at Wexford with a kind of timid outrage. “Haven’t you folk got nothing betterto do? What about the real crime? What about the street attacks and the break-ins?”Wexford sighed. But he went on persistently questioning, remembering what the nurse had said, what Dr. Moss had said, keeping in the forefront of his mind that motive, which was so much more than merely wanting an aged parent out of the way. If he hadn’t been a policeman, with a great respect for the law and for human life, he might have felt that these two, or one of them, had been angered beyond bearing to do murder.One of them? Or both? Or neither? Ivy Wrangton had either died an unnatural death or elsethere had been a series of coincidences and unexplained events which were nothing short of unbelievable.71. Wexford was slightly confused by the fact that .(A) Mrs. Betts had been so old when her mother died(B) Mr. Betts was as old as his wife’s mother(C) Mrs. Betts had lost both of her parents(D) Mr. and Mrs. Betts both denied his accusation72. Mr. Betts implied that that .(A) his mother-in-law died of old age(B) the doctor Moss had insulted them(C) the doctor who signed the death certificate made a mistake(D) he cannot fully understand the cause of the death of his mother-in-law73. Mr. Betts appears to believe that that .(A) the neighbors have been chatting about their ill-treatment of the mother-in-law(B) the police should be concentrating on other offences(C) he was not so well-educated as the doctor(D) their neighbors are too proud of themselves74. Wexford feels it is worth questioning the couple about Ivy Wrangton because that .(A) he is certain they both murdered her(B) he knew they were tired of looking after her(C) the circumstances surrounding her death were quite unusual(D) he was unsure of what their motive may have been(B)The great recession may be over, but this era of high joblessness is probably beginning.Before it ends, it will likely change the life course and character of a generation of young adults. And ultimately, it is likely to reshape our politics, our culture, and the character of our society for years.No one tries harder than the jobless to find silver linings in this national economic disaster. Many said that unemployment, while extremely painful, had improved them in some ways; they had become less materialistic and more financially prudent; they were more aware of the struggles of others. In limited respects, perhaps the recession will leave society better off. At the very least, it has awoken us from our national fever dream of easy riches and bigger houses, and put a necessary end to an era of reckless personal spending.But for the most part, these benefits seem thin, uncertain, and far off. In The Moral Consequences of Economic Growth, the economic historian Benjamin Friedman argues that both inside and outside the U.S., lengthy periods of economic stagnation or decline have almost always left society more mean-spirited and less inclusive, and have usually stopped or reversed the advance of rights and freedoms. Anti-immigrant sentiment typically increases, as does conflict between races and classes.Income inequality usually falls during a recession, but it has not shrunk in this one. Indeed, this period of economic weakness may reinforce class divides, and decrease opportunities to cross them—especially for young people. The research of Till V on Wachter, the economist in Columbia University, suggests that not all people graduating into a recession see their life chances dimmed: those with degrees from elite universities catch up fairly quickly to where they otherwise would have been if they had graduated in better times; it is the masses beneath them that are left behind.In the internet age, it is particularly easy to see the resentment that has always been hidden within American society. More difficult, in the moment, is discerning precisely how these lean times are affecting society’s character. In many respects, the U.S. was more socially tolerant entering this recession than at any time in its history, and a variety of national polls on social conflict since then have shown mixed results. We will have to wait and see exactly how these hard times will reshape our social fabric. But they certainly it, and all the more so the longer they extend.75. By saying "to find silver linings" (Line 1, Para. 2) the author suggest that the jobless tryto________.A. seek subsidies from the government.B. explore reasons for the unemployment.C. make profits from the troubled economy.D. look on the bright side of the recession.76. According to Paragraph2, the recession has made people_______.A. realize the national dreamB. struggle against each otherC. challenge their prudenceD. reconsider their lifestyles77. Benjamin Friedman believes that economic recessions may__________.A. impose a heavier burden on immigrantsB. bring out more evils of human natureC. promote the advance of rights and freedomD. ease conflicts between races and classes78. The research of Till V on Watcher suggests that in the research graduates from elite universities tend to____________.A. Lag behind the others due to decreased opportunitiesB. Catch up quickly with experienced employeesC. See their life chances as dimmed as the othersD. Recover more quickly than the others(C)Come on—Everybody’s doing it. That whispered message, half invitation and half forcing, is what most of us think of when we hear the words peer pressure. It usually leads to no good—drinking, drugs and casual sex. But in her new book Join the Club, Tina Rosenberg contends that peer pressure can also be a positive force through what she calls the social cure, in which organizations and officials use the power of group dynamics to help individuals improve their lives and possibly the world.Rosenberg, the recipient of a Pulitzer Prize, offers a host of examples of the social cure in action: In South Carolina, a state-sponsored antismoking program called Rage Against the Haze sets out to make cigarettes uncool. In South Africa, an HIV-prevention initiative known as LoveLife recruits young people to promote safe sex among their peers.The idea seems promising, and Rosenberg is a perceptive observer. Her critique of the lameness of many pubic-health campaigns is spot-on: they fail to mobilize peer pressure for healthy habits, and they demonstrate a seriously flawed understanding of psychology. "Dare to be different, please don’t smoke!" pleads one billboard campaign aimed at reducing smoking among teenagers teenagers, who desire nothing more than fitting in. Rosenberg argues convincingly that public-health advocates ought to take a page from advertisers, so skilled at applying peer pressure.But on the general effectiveness of the social cure, Rosenberg is less persuasive. Join the Club is filled with too much irrelevant detail and not enough exploration of the social andbiological factors that make peer pressure so powerful. The most glaring flaw of the social cure as it’s presented here is that it doesn’t work very well for very long. Rage Against the Haze failed once state funding was cut. Evidence that the LoveLife program produces lasting changes is limited and mixed.There’s no doubt that our peer groups exert enormous influence on our behavior. An emerging body of research shows that positive health habits—as well as negative ones—spread through networks of friends via social communication. This is a subtle form of peer pressure: we unconsciously imitate the behavior we see every day.Far less certain, however, is how successfully experts and bureaucrats can select our peer groups and steer their activities in virtuous directions. It’s like the teacher who breaks up the troublemakers in the back row by pairing them with better-behaved classmates. The tactic never really works. And that’s the problem with a social cure engineered from the outside: in the real world, as in school, we insist on choosing our own friends.79. According to the first paragraph, peer pressure often emerges as_______.A. a supplement to the social cureB. a stimulus to group dynamicsC.an obstacle to school progressD. a cause of undesirable behavior80. Rosenberg holds that public advocates should_______.A. recruit professional advertisersB. learn from advertisers’ experienceC. stay away from commercial advertisesD. recognize the limitations of advertisements81. In the author’s view, Rosenberg’s book fails to________.A. adequately probe social and biological factorsB. effectively evade the flaws of the social cureC. illustrate the functions of state fundingD. produce a long-lasting social effect82. The author suggests in the last paragraph that the effect of peer pressure is______.A. harmfulB. desirableC. profoundD. questionable（D）Depending on whom you believe, the average American will, over a lifetime, wait in lines for two years (says national public radio) or five years (according to some customer-loyalty experts). The crucial word is average, as wealthy Americans routinely avoid lines altogether. Once the most democratic of institutions, lines are rapidly becoming the exclusive province of suckers (people who still believe in and practice waiting in lines). Poor suckers, mostly. Airports resemble France before the Revolution: first-class passengers enjoy "elite" security lines and priority boarding, and disembark before the unwashed in coach, held at bay by a flight attendant, are allowed to foul the Jet-way. At amusement parks, too, you can now buy your way out of line. This summer I haplessly watched kids use a $52 Gold Flash Pass to jump the lines at Six Flags New England, and similar systems are in use in most major American theme parks, from Universal Orlando to Walt Disney World, where the haves get to watch the have-mores breeze past on their way to their seats. Flash Pass teaches children a valuable lesson in real-world economics; that the rich are more important than you, especially when it comes to waiting. An NBA player once said to me, with a bemused chuckle of disbelief, that when playing in Canada—get this—"We have to wait in the same customs line as everybody else. " Almost every line can be breached for a price. In several U. S. cities this summer, early arrivers among the early adopters waiting to buy iPhones offered to sell their spots in the lines. On Craigslist, prospective iPhone purchasers offered to pay "waiters" or "placeholders" to wait in line for them outside Apple stores. Inevitably, some semi-populist politicians have seen the value of sort-of waiting in lines with the ordinary people. Billionaire New York mayor Michael Bloomberg often waits for the subway with his fellow citizens, though he's first driven by motorcade past the stop nearest his house to a station 22 blocks away, where the wait, or at least the ride, is shorter. Nothing annoys a national lawmaker more than a person who will not wait in line, unless that line is in front of an elevator at the U. S. Capitol, where Senators and Representatives use private elevators, lest they have to queue with their constituents. But compromising the integrity of the line is not just antidemocratic, it's out-of-date. There was something about the orderly boarding of Noah's Ark, two by two, that seemed to restore not just civilization but civility during the Great Flood. Howcivil was your last flight？Southwest Airlines has first-come, first-served festival seating. But for $ 5 per flight, an unaffiliated company called Board First. com will secure you a coveted "A" boarding pass when that airline opens for online check-in 24 hours before departure. Thus, the savvy traveler doesn't even wait in line when he or she is online. Some cultures are not renowned for lining up. Then again, some cultures are too adept at lining up: a citizen of the former Soviet Union would join a queue just so he could get to the head of that queue and see what everyone was queuing for. And then there is the US, where society seems to be cleaving into two groups; Very Important Persons, who don’t wait, and Very Impatient Persons, who do-unhappy.83. What does the following sentence mean? ”Once the most democratic of institution, lines are rapidly becoming the exclusive province of suckers… Poor suckers, mostly. ”(2 paragraph)A. Lines are symbolic of America’s democracyB. Lines still give Americans equal opportunities.C. Lines are now for ordinary Americans only.D. Lines are for people with democratic spirit only.84. Which of the following is NOT cited as an example of breaching the line? A. Going through the customs at a Canadian airport. B. Using Gold Flash Passes in amusement parks. C. First-class passenger status at airports. D. Purchase of a place in a line from a placeholder.85. We can infer from the passage that politicians (including mayors and Congressmen) _______.A. prefer to stand in lines with ordinary people.B. advocate the value of waiting in lines.C. believe in and practice waiting in lines.D. exploit waiting in lines for their own good.86. What is the tone of the passage?A. InstructiveB. HumorousC. SeriousD. Indifferent（E）A. In large settings, people reported feeling more powerful and were likelier to steal money, cheat on a test, and commit traffic violations.B. How honest a person is depends mainly on his or her personality.C. This held true even when people were role-playing----that is, they weren’t rich real life.D. When Dutch psychologist Gerben van Kleef asked study participants that question, most chose the second accountant.E. Researchers find it very common among “successful” people but can’t explain why.F. The more wins, the higher the hormones, the greater the confidence boost, thebigger the risks, and so on.Picture two accountants alerted to suspicious entries in the books. The first takes the violation seriously. The second thinks it’s not a big deal. Who has more power? ____67______ Powerful people break the rules-----therefore, breaking rules makes one seem more powerful. “In its modest form, rule breaking is actually healthy,” says Zhen Zhang of Arizona State University. He found that relatively minor violations during adolescence----damaging property, playing hooky----predicated an admired occupation entrepreneur. When young men, in particular, take risks that succeed, testosterone levels surge. The hormone may underline the “winner effect,” say researchers John Coates and Joe Herbert of University of Cambridge, who tracked the hormonal activity of stock option traders (again, all male) over their good and bad days in the market _____68______. But at a certain point, risk taking can become illogical. This can cause “ethical numbing(道德麻木).” Consider Steve Jobs: As Apple grew, so did lawsuits against it, like those over patents. Being wealthy has a moral effect on both genders. Studies have found that the $150,000-plus per-year set was four times as likely to cheat as those making less than $15,000 a year when playing a game to win $50. The rich didn’t stop for pedestrians at a crosswalk nearly as often as less-wealthy drivers. ______69_____ That’s because environment—not personality—encourage rule breaking, argues Andy Yap, a behavioral scientist. Yap and his colleagues asked volunteers to sit in an SUVsize driver’s seat versus a crowded one or an executive-size office space versus a cubicle(小隔间) and then tested their responses to various moral evens. _____70______.Section C （10%）Directions: Read the following passage. Summarize the main idea and the main point(s) of the passage in no more than 60 words. Use your own words as far as possible.Judging from recent surveys, most experts in sleep behavior agree that there is virtually an epidemic（流行病）of sleepiness in the nation．”I can’t think of a single study that hasn’t found Americans getting less sleep than they ought to,” says Dr.David. Even people who think they are sleeping enough would probably be better off with more rest.The beginning of our sleep-deficit（睡眠不足）crisis can be traced back to the invention ofthe light bulb a century ago．From diary entries and our personal accounts from the 18th and 19thcenturies, sleep scientists have reached the conclusion that the average person used to sleep about 9.5 hours a night. ”The best sleep habits once were forced on us, when we had nothing to do in the evening down on the farm, and it was dark.” By the 1950s and 1960s, the sleep schedule had been reduced dramatically, to between 7.5 and 8 hours, and most people had to wake to an alarm clock. “People cheat in their sleep, and they don’t even realize they’re doing it,” says Dr.David, ”They think they’re okay because they can get by on 6.5 hours, when they really need 7.5, 8 or even more to feel ideally vigorous. ”Perhaps the most merciless robber of sleep, researchers say, is the complexity of the day．Whenever pressures from work, family, friends and community increase, many people consider sleep the least expensive item on their programme.” In our society, you’re considered dynamic if you say you need only 5.5 hours’ sleep. If you’ve got to get 8.5 hours, people think you lack drive and ambition. “To determine the consequences of sleep-deficit, researchers have put subjects through a set of psychological and performance tests requiring them, for instance, to add columns of numbers or recall a passage read to them only minutes earlier.” We’ve found that if you’re in sleep deficit, performance suffers,” says Dr. David, ”Short-term memory is weakened, as are abilities to make decisions and to concentrate.”V.

This seems far from the truth. Young people today as a whole are better, more informed, more ambitious, healthier, and more alert than ever before. Why then, it may be asked, do we witness such restlessness and such anti-social behavior among our young people?For the answer the citizens of this community must look at themselves. What have they done to improve the life of our youth? How many playgrounds have been built in the last fifteen year? How many swimming pools? How many vocational training projects have been started? How many community-organized youth parties and picnics have been held?The average citizen will answer that the responsibility for these activities belongs to the schools. But the schools cannot be held responsible for all the free-time activities of all the young people of this community. The job of the schools is formal education, not freetime entertainment.This community needs a youth center suitable for such activities as picnics, camping, sports, music, art, and theatricals. There could be social and entertaining activities to meet the needs and interests of every member of out school age youth.Mayor Elmo D. Greely has proposed the formation of a Youth Club as the first step in the direction of a Youth Center. Mayor Greely has called a meeting at the City Hall on Friday, August 15.36. What does the writer think of the underlined sentence?A. He thinks it is true.B. He thinks it is not true.C. He thinks it is partly true.D. He thinks it is nonsense.37. The main idea of paragraph 2 and 3 is ________.A. to give us lots of questions to show that the problem is seriousB. that schools should hold the responsibility for education rather than entertainmentC. to analyze the reasons why the youth are anti-socialD. that schools should take more activities or star many vocational training projects38. The solution to the problem of the youth's anti-social behavior is___________.A. enriching the life of the youthB. taking part in picnics, campingC. attending a meeting held by MayorD. needing support from youth39. Which of the following is the best title for the passage?A. The anti-social problem,B. The duty of formal education.C. A Youth Club is Needed.D. A Youth Center is Needed.BAustralia has very strict lawsrelating to the importation andpossession of certain goods. Food, plantmaterial and animal products fromoverseas--including many commonsouvenirs -could introduce some of the world's most serious pests and diseases into Australia. Failing to declare quarantine items (需要(xūyào)检疫的物品) on arrival could destroy our agriculture, tourism industries and special environment.Every piece of luggage will be screened or x-rayed on arrival in Australia. So you must declare for inspection of all food, plant material and animal products to check that they are free of pests and diseases.You must tick YES on the Incoming Passenger Card(IPC) to declare if you are carrying any food, plant material or animal products. In signing the IPC, passengers are making a legal declaration and failure to answer all questions truthfully can have serious consequences.If you fail to declare or dispose of any quarantine items, or make a false declaration:* you will get caught;* you could be fined over A $ 200 on-the-spot; or* you could be prosecuted and fined more than A $ 60,000 and risk up to 10 years imprisonment;If you are not sure about the items you are carrying, ask a quarantine officer who will determine whether they are allowed into Australia.40. The reason why you are asked to declare quarantine items on arrival is that _________.A. too many overseas products could destroy Australia's tourism industry.B. animal products are often the cause of various diseases.C. as is known to us all, bad food can spread diseases easily.D. these items may carry dangerous pests or diseases into Australia.41. You need to declare the following things EXCEPT _______ if you have them in your luggage.A. some metal hairclipsB. dried flowersC. some moon-cakesD. a bottle of honey42. For what purpose is the passage written?A. To inform the passengers of the law on the exportation of goods.B. To warn the passengers not to take unsafe goods.C. To tell the passengers to Australia to have their quarantine items declared.D. To urge the passengers to protect the agriculture, tourism and environment.43. If you don't declare quarantine items, ________.A. you can probably get away with itB. you are sure to be discovered and punishedC. you can turn to the customs officers for helpD. you can give them away to a quarantine officerCToday every independent country has a flag that gives them a unique identity. Usually there is a story and meaning behind each flag. The colours used on a national flag are not used simply because they look good--they usually symbolize something about the growth, values and culture of that country. Sometimes colours mean the same thing in different cultures, but they can often mean different things to people in different cultures.The French flag, sometimes called the "Tricolore", was first used in 1789, after the French Revolution The conclusion of the French Revolution led up to big changes throughout the country. Before the Revolution, there was great unrest because people did not have freedom and had often been treated unfairly. Many people died of starvation. After the Revolution,people had far more freedom, and people were considered equal, and large numbers of people were no longer starving.The colours red, white and blue used on the flag represent the principles of the Revolution-liberty, equality and friendship. Red represents bravery, revolution strength and blood. All these things were needed to change the country. Blue stands for liberty and justice while white represents peace.Strengthened by the Revolution, France became a different country soon after, and today, it is still guided by those beliefs. That France's revolution which was successful in ridding society of inequality had a big effect on many other countries, especially in Europe. Some countries elected to substitute their flags with tricolor flags, after the French. In this way, the French Tricolor has become one of the most influential national flags in history.The USA was also born from revolution, and its flag, the "Stars and Stripes", represents this. The USA was originally an area owned and occupied by Britain. At that time, there were thirteen states, which is far fewer than the fifty that make up today's USA. Some people are very unhappy with the bureaucratic way Britain ruled the country, and were quite outspoken about this. American taxpayers could no longer toleratethat they had no say in the government. They desired independence, but the British opposed this. The Americans saw that their freedom was no longer optional and that their independence would not be won by being passive. On 4 July 1776, the American Declaration of Independence was signed. With this, the USA split from Britain and became an autonomous nation with a federal government.The colours red, white and blue and the stars and stripes on the American flag are all very symbolic. Red represents strength and bravery; white represents purity and innocence; blue stands for hard work and justice. There are fifty stars on the American flag, one for each state. The thirteen stripes represent the original thirteen states that joined together to fight for independence.Each year, on 4 July, the USA celebrates Independence Day when the Stars and Stripes" can be seen all over the country, lit by fireworks in the night sky.44. The passage is mainly aboutA. national flags, colours and culturesB. different colours and culturesC. colours and national flagsD. revolution, cultures and colours45. Which of the following statements is NOT true?A. Red represents bravery and strength both in France and the USAB. Blue stands for liberty and justice in the USA but hard work and justice in France.C. Colours on national flags usually stand for special things of the countries.D. Generally every national flag has its own story.46. If a country is newly born in Europe from revolution, how would it be likely todesign its national flag?A. In three colours, after the USAB. With stars and stripes.C. In three colours with stars and stripes.D. In three colours, following France.DThere are so many different plastic cards that adults have to carry around—library cards, savings cards for different banks, credit cards, just to name a few... So why not have one to replace them all?Scott Barnhill, an 1l-year-old fifth-grade student in the US, has come up with an idea for a "Security One Card".Sound smart? The US Patent(专利(zhuānlì)) Office thought so, and it approved a patent for his idea in April.Here's an example of how Barnhill's idea would work.Let's say you have the three cards mentioned above. Instead of carrying them all, you could have just one by having additional magnetic strips(磁条) added to it.The magnetic strips can be added to any plastic card, even a blank one.Companies could add their information to one of the strips. For example, you could ask a library to add a strip to your bankcard.Barnhill has a lot of hobbies, including designing websites. He got the idea at the age of 9 when he saw his father using a keycard to enter their hotel room. He thought, "The hotels are wasting money with the key cards." So, instead of using a hotel-issued key card, guests could use their credit cards--if the hotel added a special magnetic strip. At check-out, the strip would simply be removed.Now that he has his patent, his next step is a letter-writing campaign to get support from major credit card companies."I'm going to be writing letters to credit card companies to ask if they can co-operate. I hope they'll give me money every time someone puts a strip on the back of another card, or every time the idea is used, " Barnhill said. "I'll write the letters and see what they say. If they say no, I'll ask someone else, another credit card company."He is hoping to make money from his patent and has decided it would be better to collect royalties(专利(zhuānlì)使用费)if the idea takes off rather than sell his patent."The ATM person who invented that sold it totally, and if he'd chosen royalties he'd get like 2 cents for every transaction (交易) and he'd be a billionaire now," Scott said.47. the advantage of “Security One Card〞 is that it ___________.A. could remove the burden of taking all kinds of plastics cardsB. would be very safeC. could save your moneyD. could have a lot of magnetic strips on it48. The immediate cause of Scott's invention was that _________.A. he found that adults have to carry around so many plastic cardsB. he realized it's big waste to make so many plastic cards instead of only oneC. he found even a hotel issued its own cards--keycardsD. he realized it would be a good chance to make big money49. To use a "Security One Card", ___________.A. one has to add additional magnetic strips to it oneselfB. one has to pay Scott Barnhill each time a magnetic strip is addedC. all the companies need to add their information to a magnetic strip by themselvesD. one has to get the permission of the credit card company first50. The underlined phrase "takes off" in the last but one paragraph probably means ______.A. makes moneyB. wins a lot of supportC. is worth a lotD. is practical51. From the story, we can see Scott is ___________.A. more magic than smartB. clever but lazyC. creative, determined and wiseD. far-sightedEUnited States President George W. Bush is expected to issue a directive in the next few weeks. It will give the US Air force a green light for the development of space weapons, US media reported last week.This would potentially trigger a new global arms race, some experts have warned.To keep that from happening, last Wednesday the White House explained that it was not considering putting weapons in space. It said it was making a shift in US space policy to allow for protection of satellites.But some defense analysts and arms control advocates argue that the policy will pave the way for the US to put both defensive and offensive weapons in space."No one should be fooled," said Theresa Hitches, an American weapons expert.The US is now restricted by a 1996 directive signed by President Bill Clinton. Plans for space weapons were vetoed by the Clinton cabinet. The directive emphasized the peaceful use of space, in agreement with almost unanimous(一致(yīzhì)的) global opinion.The US military has placed importance on space and has sent up numerous satellites for troop communications and to provide intelligence and data to guide bombs to their targets.The US Air force wants to develop space-based weapons that could strike targets any where in the world within 90 minutes of receiving the order to open fire.These new weapons under development cover a wide range. They include hunter-killer satellites(HY卫星) and orbiting weapons(沿轨道运行的武器系统). And they use lasers, radio waves, or even dense metal tubes, known as "Rods from God", dropped from space to do the damage.There are many barriers to the setting up of this kind of program, experts say.First is the cost. It is estimated that the budget may be US $ 220 billion to US $1 trillion. The technical difficulties of developing reliable space weapons are also a problem. And, the move will draw strong criticism from around the world. Experts worry about triggering a space arms race.52. The news report mainly deals with ______.A. US Military Plans.B. The Global Arms RaceC. A Comparison between Two presidents.D. President George W. Bush and the World Peace53. Which of the following statements are mentioned in the passage above?a. President George W. Bush supports space weapon development.b. The US space weapon project is very costly.c. The American space-based weapons to be developed will be able to target any place on the earth.d. The US military has few difficulties with the development of space weapons.e. The space weapon program will threaten world peace.f. Clinton government was poorer than Bush government.A. b,d,e,fB. a,c,d,fC. b,c,d,eD. a,b,c,e54. After reading this passage, it can be inferred that _________.A. George W. Bush's directive to be issued will be against global opinions.B. The White House is right in explaining that US new space policy aims to protect satellites.C. US government has little difficulty in developing new weapons.D. President George W. Bush and Bill Clinton share a lot in common.55. The author's attitude towards the upcoming space weapon development is ________.A. supportive and optimisticB. critical and worriedC. excited and contentD. indifferent but a little encouraged第四节：对话(duìhuà)填空〔一共10小题，每一小题1分，满分是10分〕第五节：书面表达(biǎodá)(满分是25分)周笔畅宣布退出“超女〞演唱会巡演，重返校园。

As a result51-65 A B C B D A B D D C A C B D BDProbably the number one complaint about reading Shakespeare is that it doesn't always read like "normal" English. It’s a natural and reasonable 51 . Shakespeare wrote for an audience over 400 years ago. Think about how word meanings and expressions change over arelatively short time; four centuries bring with them a lot of 52 . The Renaissance and England’s emerging status as a sea power 53 the language to an ever-increasing range of cultures and languages. At thesame time, there was no real standardization in English. formal dictionaries and grammar textbooks 54 did not exist, and "proper" education focused much more on classical Latin than on colloquial English. Despite this neglect---or perhaps because of it---English by the reign of Elizabeth had a certain flexibility to it, of which Shakespeare 55 .So how can a reader today 56 that gap between then and now? There are two critical areas to 57 :word usage and grammar. Once you understand these fundamental concepts, Shakespeare becomes a lot more 58 .First and foremost, there have been numerous vocabulary changes in English since Shakespeare was writing. while many words are still recognizable today, others have shifted in their meaning or dropped altogether from usage.59 ,when was the last time you heard anyone use words such as bodkin(a piercing tool), contumely(verbal abuse),or fardel (a bundle)?Often the context in which a word is used will help you determine its meaning. A good 60 with detailed footnotes will help you, as well as a good dictionary. The main thing is to be aware that even a familiar word from today may be used with a different meaning in Shakespeare's works. Grammar is where the 61 of Shakespeare's English is often most apparent. 62 of speech are frequently switched, such as nouns or adjectives becoming verbs. Verbs and subjects don't always 63 .
