单选题 Results showed that at least a tenth of the Harvard first-year undergraduates polled admitted to having cheated on an exam prior to starting at the university, while almost half admitted to cheating on their homework. An anonymous survey by Harvard's newspaper has revealed a surprising pattern of academic dishonesty among students entering the US universities. The survey by The Harvard Crimson was emailed to the incoming first year undergraduates; 1,600 students responded. Results showed that at least a tenth of the students polled admitted to having cheated on an exam prior to starting at the university, while almost half admitted to cheating on their homework. Athletes were apparently the most prone to cheating. 20 percent of students who played a university sport admitted to cheating on an exam compared to 9 percent of students who did not. The survey also revealed that men were not only more likely to cheat but were also more likely to admit to it. The results, compared to a previous survey done on the class of 2013, suggested that cheating may be becoming more commonplace. Of the outgoing seniors only 7 percent admitted to cheating in an exam and another 7 percent said they had been dishonest on a take-home test. 32 percent of the seniors said they had cheated on homework during their undergraduate years... The surveys come in the wake of a cheating scandal at the university which saw 120 students investigated for sharing answers on an exam in 2012. One recent graduate stated: 'Cheating was commonplace when I was at Harvard, especially with students in their first year or two. I would say as many as 60 percent of students took notes into some exams. No one really cared the faculty, well some of them at least, seemed to recognize and yet ignore the problem.' In an email to NBC News, Jeff Neal, a Harvard representative, explained that a committee, made up of faculty, staff and students had been established to tackle cheating, which 'is a national problem in American education'. He added: 'While the vast majority of Harvard and other students do their work honestly, beginning this year Harvard College has implemented a new, more robust strategy of communicating with all students, particularly first-year students, about the importance—and the ways to achieve—academic integrity.' In a rebuff to critics who say university has become little more than an expensive party, 84 percent of the responding undergraduates fully expected to prioritize their academics over extracurricular activities, sport, employment and their social lives. Not a single student put academics at the bottom of their list. Not content with confining themselves to their degree subject, 59 percent of incoming students expressed a desire to pursue a secondary field of study, and 36 percent hoped to learn a language.

单选题 Last summer, the missing white-letter hairstreak butterfly was spotted in Scotland for the first time in 133 years. Conservationists wondered if the creature had established a breeding colony in the country—and a new discovery suggests there is good reason to be optimistic. As Russell Jackson reports for the Scotsman, volunteer naturalists recently found a cluster of tiny white-letter hairstreak eggs on an elm tree in Lennel, a small village near the country of Berwickshire. Volunteers with the UK's Butterfly Conservation have been carefully tracking white-letter hairstreak migrations for more than ten years. The butterfly, which boasts a distinctive 'W' pattern on the underside of its wings, is native to the U.K. and was once widespread in England and Wales. But white-letter hairstreak numbers have declined drastically in recent decades, largely due to an outbreak of Dutch elm disease, an illness that took hold in the 1960s. The disease has killed millions of British elm trees, which is the food source for white-letter hairstreak caterpillars (蝴蝶或蛾的幼虫). Recently, there have been signs that the butterfly's populations are recovering. The Butterfly Conservation team has observed the white-letter hairstreak gradually spreading northwards, possibly due to warming climates. But the white-letter hairstreak is still a very rare sight in Scotland, and the volunteers who found the cluster of eggs—Ken Haydock and Jill Mills—were thrilled by the discovery. 'It was a lovely sunny morning and we were searching the elm trees by the River Tweed at Lennel when Jill called me over,' Haydock says in a Butterfly Conservation statement. 'I could see by the look on her face that she had found something. We were both smiling with disbelief and delight when we realized what Jill had found and within seconds I was fumbling in my pack for the camera—my hands were shaking!' That Haydock and Mills managed to spot the eggs is quite remarkable; according to Vittoria Traverso of Atlas Obscura, white-letter hairstreak eggs are smaller than a grain of salt. The volunteers were also excited to discover an old, hatched eggshell amid the cluster of new eggs. According to the Butterfly Conservation, this suggests that the white letter hairstreak could have been breeding in the area since at least 2016. Paul Kirkland, the director of the Butterfly Conservation's Scotland chapter, says in the statement that conservationists will 'need to have a few more years of confirmed sightings' before they can classify the white-letter hairstreak as a resident species of Scotland. 'If this happens, it would take the total number of butterflies found in Scotland to 34,' he says, 'which really would be something to celebrate.'

单选题 A Few Aspects of American Life Travel A. It's summer time. For many Americans, this is the season to travel. Why? Because school is over and the weather is great. And most of all, they believe they deserve a break. When Americans take a break, they often head for their favorite vacation spot. B. Throughout their history, Americans have been people on the move. The early immigrants had to travel to get to the New World. Once they arrived, they settled along the East Coast. But they weren't content to stay here. Explorers and traders journeyed to the unknown western territories. Later, settlers moved west to develop new areas. As a result of this west movement, Americans eventually occupied the whole continent—from the Atlantic to the Pacific. Even today, Americans seem unable to stay put. Research says that average American moves every five years. C. Americans are used to traveling. Some people make long-distance commuting to work daily. Their jobs may even require them to take frequent business trips. Most companies provide an annual vacation for their employees, and people often use that time to travel. Some people just visit friend or relatives in distant states. Some go on low-budget weekend trips and stay in economy motels. Those with more expensive tastes choose luxurious hotels. Camping out in the great outdoors appeals to adventurous types. Some travel in recreational vehicles to camp out in comfort, while others 'rough it' by sleeping in tents. Families often plan their trips with the kids in mind. More and more 'family friendly' hotels offer special programs for children. Pet D. Americans love pets. Many pet owners treat their pets as a part of the family. You might say Americans treat their pets like they treat their children—sometimes even better. E. In America, there are more households with pets than those with children. At least 43 percent of US homes have pets of some sort. Usual creatures, such as monkeys, snakes and even wolves, find a home with some Americans. More common pets include fish, mice and birds. But the all-time favorites are cats and dogs, even at the White House. Americans sometimes have strong feelings about whether dogs or cats make better pets. 'Dog people' and 'cat people' often enjoy friendly competition. F. Many grocery stores in America sell pet foods. Pets can even accompany their owners on vacation. Fancy hotels are beginning to accommodate both man and animal. Animal guests at Four Seasons Hotels can enjoy delicious meals served on fine china and sleep in soft beds. G. The average American enjoys having pets around, and for good reason. Researchers have discovered that interacting with animals lowers a person's blood pressure. Dogs can offer protection from robbers and unwelcome visitors. Cats can help rid the home of unwanted mice. Little creatures of all shapes and sizes can provide friendship and love. In many cases, having a pet prepares a young couple for the responsibilities of parenthood. Pets even encourage social relationships: they give their owners an appearance of friendliness, and they provide a good subject of conversation. H. Pets are as basic to American culture as hot dogs or apple pie. To Americans, pets are not just property, but a part of the family. Marriage I. 'I do.' To Americans, these two words carry great meaning. They can even change your life, especially if you say them at your own wedding. Making wedding promises is like signing a contract. Now Americans don't really think marriage is a business deal. But marriage is a serious business. J. It all begins with engagement. Traditionally, a young man asks the father of his sweetheart for permission to marry her. If the father agrees, the man later proposes to her. Often he tries to surprise her by asking her to marry him in a romantic way. K. Sometimes the couple just decides together that the time is right to get married. They may be engaged for weeks, months or even years. As the big approaches, bridal showers and bachelor's parties provide many gifts. Today many couples also receive counseling during engagement. This prepares them for the challenges of married life. L. At last it's time for the wedding. Although most weddings follow long-held traditions, there's still room for individualism. For example, the usual place for a wedding is in a church. But some people get married outdoors. A few even have the ceremony while skydiving or riding on horseback! The couple may invite hundreds of people or just a few close friends. They choose their own style of colors, decorations and music during the ceremony. But some things rarely change. The bride usually wears a beautiful, long white wedding dress. She traditionally wears 'something old, something new, something borrowed and something blue'. The groom (新郎) wears a formal suit. Relatives and close friends participate in the ceremony. M. As the ceremony begins, the groom stands with the minister, facing the audience. Music signals the entrance of the beautiful bride. Nervously, the young couple repeats their promises. Traditionally, they promise to love each other 'for better, for worse, for richer, for poorer, in sickness and in health'. But sometimes the couple composes their own promises. They give each other a gold ring as a symbol of their marriage promise. Finally the minister announces the big moment: 'I now pronounce you man and wife. You may kiss your bride!'
