单选题Northern Europeans are willing to pay a lot of money and put up with a lot of inconveniences for the sun because they have so little of it. Residents of cities like London, Copenhagen, and Amsterdam spend a lot of their winter in the dark because the days are so short, and much of the rest of the year is in the rain. This is the reason the Mediterranean has always attracted them. Every summer, more than 25 million people travel to Mediterranean resorts and beaches for their vacation. They all come for the same reason : sun ! The huge crowds mean lots of money for the economies of Mediterranean countries. Italy's 30, 000 hotels are booked solid every summer. And 13 million people camp out on French beaches, parks, and roadsides. Spain's long sandy coastline attracts more people than anywhere else. 37 million tourists visit yearly ,or one tourist for every person living in Spain. How large is probably the Spanish population?A. 13 million.B. 30,000.C. 37 million.D. Not mentione

单选题On Sleep Baekeland and Hartmann report that the "short sleepers" had been more or less average in their sleep needs until the men were in their teens. But at about age 15 or so, the men voluntarily began cutting down their nightly sleep time because of pressures from school, work, and other activities. These men tended to view their nightly periods of unconsciousness as bothersome interruptions in their daily routines. In general, these "short sleepers" appeared ambitious, active, energetic, cheerful, conformist (不动摇) in their opinions, and very sure about their career choices. They often held several jobs at once, or workers full or part-time while going to school. And many of them had a strong urge to appear "normal" or "acceptable" to their friends and associates. When asked to recall their dreams, the "short sleepers" did poorly. More than this, they seemed to prefer not remembering. In similar fashion, their usual way of dealing with psychological problems was to deny that the problem existed, and then to keep busy in the hope that the trouble would go away. The sleep patterns of the "short sleepers" were similar to, but less extreme than, sleep patterns shown by many mental patients categorized as manic (疯人). The "long sleepers" were quite different indeed. Baekeland and Hartmann report that these young men had been lengthy sleeps since childhood. They seemed to enjoy their sleep, protected it, and were quite concerned when they were occasionally deprived of their desired 9 hours of nightly bed rest. They tended to recall their dreams much better than did the "short sleepers". Many of the "long sleepers" were shy, anxious, introverted (内向), inhibited (压抑), passive, mildly depressed, and unsure of themselves (particularly in social situations). Several openly states that sleep was an escape from their daily problems.

单选题Problems of Internet The proportion of works cut for the cinema in Britain dropped from 40 per cent when I joined the BBFC in 1975 to less than 4 per cent when I left. But I don"t think that 20 years from now it will be possible to regulate any medium as closely as I regulated film. The Internet is, of course, the greatest problem for this century. The world will have to find a means, through some sort of international treaty of United Nations initiative, to control the material that"s now going totally unregulated into people"s homes. That said, it will only take one little country like Paraguay to refuse to sign a treaty for transmission to be unstoppable. Parental control is never going to be sufficient. I"m still very worried about the impact of violent video games, even though researchers say their impact is moderated by the fact that players don"t so much experience the game as enjoy the technical manoeuvres (策略) that enable you to win. But in respect of violence in mainstream films, I"m more optimistic. Quite suddenly, tastes have changed, and it"s no longer Stallone or Schwarzenegger who are the top stars, but Leonardo DiCaprio—that has taken everybody by surprise. Go through the most successful films in Europe and America now and you wilt find virtually none that we are violent. Quentin Tarantino didn"t usher in a new, violent generation, and films are becoming much more prosocial than one would have expected. Cinemagoing will undoubtedly survive. The new multiplexes are a glorious experience, offering perfect sound and picture and very comfortable seats, thins which had died out in the 1980s. I can"t believe we"ve achieved that only to throw it away in favor of huddling around a 14-inch computer monitor to watch digitally-delivered movies at home. It will become increasingly cheap to make films, with cameras becoming smaller and lighter but remaining very precise. That means greater chances for new talent to emerge, as it will be much easier for people to learn how to be better film-makers. People"s working lives will be shorter in the future, and once retired they will spend a lot of time learning to do things that amuse them—like making videos. Fifty years on we could well be media-saturated as producers as well as audience; instead of writing letters, one will send little home movies entitled My Week.

单选题Sleepless at Night It was a normal summer night. Humidity (湿气 hung in the thick air. I couldn't go to sleep, partly because of my cold and partly because of my expectations for the next day. My mum had said that tomorrow was going to be a surprise. Sweat stuck to my aching body. Finally, I gathered enough strength to sit up. I looked out of my small window into the night. There was a big bright moon hanging in the sky, giving off a magic glow. I couldn't stand the pressure anymore, so I did what I always do to make myself feel better. I went to the bathroom and picked up my toothbrush and toothpaste. I cleaned my teeth as if there was no tomorrow. Back and forth, up and down. Then I walked downstairs to look for some signs of movement, some life. Gladiator, my cat, frightened me as he meowed (喵喵地唱出) his sad song. He was on the old orange couch (长沙发), sitting up on his front legs, waiting for something to happen. He looked at me as if to say, "I'm lonely, pet me. I need a good hug (紧抱)." Even the couch begged me to sit on it. In one movement I settled down onto the soft couch. This couch represented my parents' marriage, my birth, and hundreds of other little events. As I held Gladiator, my heart started beating heavily. My mind was flooded with questions: What's life? Am I really alive? Are you listening to me? Every time I moved my hand down Gladiator's body, I had a new thought; each touch sang a different song. I forgot all about the heat and the next day's surprise. The atmosphere was so full of warmth and silence that I sank into its arms. Falling asleep with the big cat in my arms, I felt all my worries slowly move away.

单选题The Origin of the Air Mail At Blackpool Holt Thomas and Graham-White agreed to make a practical experiment in carrying mails by aeroplane. The idea,as it was first worked out, was for the aeroplane to fly from Blackpool airport across to Southport airport, and for the mails to be taken over by the Post Office there. But the programme had to be changed owing to a series of high winds. What happened in the end was that Graham-White took a mail-bag in his plane , and made a flight with it across country for a distance of about seven miles,returning to the airport. This experiment gave Graham-White the honour of being the first airman in England to carry a bag of mail across country in an aeroplane. Letters and postcards which were carried in this test,and which had a special stamp recording the fact,soon became much sought after by collectors. The second and more important experiment in British air mail transport took place in September 1911 ,and was the first of its kind in this country to obtain the official permission of the Postmaster-general. It was indeed one of the historical events in our airmail development. In this case as many as 130,000 letter and postcards were carried by aeroplane between London and Windsor. One of the airmen engaged in this pioneer service was the famous Gustav Hamel,flying a monoplane. I remember going out one afternoon to see him start off with one of the bags of mail. It was an extremely bad day for flying ,and just before the time due for the start,the wind was blowing at nearly 50 miles an hour. None of the other pilots would have thought of going up,but Hamel--one of the finest of all pilots of the British monoplane--was not to be stopped. He jumped into his machine and fairly shot off the ground. The monoplane, so long as it was near the earth, was thrown about like a small boat on an angry sea. But Hamel gave a splendid exhibition of airmanship;as soon as he reached a great height, conditions became much steadier ,and her finished his journey without accident. This was an early demonstration that an airplane was more than a fine weather machine, and that it could fight its way successfully through violent winds. This fact impressed the postal authorities a good deal,and helped those who believed that the airplane had a great commercial future.

单选题下面有3篇短文，每篇短文后有5道题，每道题后面有4个选项。请仔细阅读短文并根据短文回答其后面的问题，从4个选项中选择1个最佳答案。{{B}}第一篇{{/B}} Clone Farm Factory farming could soon enter a new era of mass production. Companies in the US are developing the technology needed to "clone" chickens on a massive scale. Once a chicken with desirable traits has been bred or genetically engineered, tens of thousands of eggs, which will hatch into identical copies, could roll off the production lines every hour. Billions of clones could be produced each year to supply chicken farms with birds that all grow at the same rate, have the same amount of meat and taste the same. This, at least, is the vision of the US's National Institute of Science and Technology, which has given Origen Therapeutics of Burlingame, California, and Embrex of North Carolina $ 4.7 million to help fund research. The prospect has alarmed animal welfare groups, who fear it could increase the suffering of farm birds. That's unlikely to put off the poultry industry, however, which wants disease resistant birds that grow faster on less food. "Producers would like the same meat quantity but to use reduced inputs to get there. " says Mike Fitzgerald of Origen. To meet this demand, Origen aims to "create an animal that is effectively a clone", he says. Normal cloning doesn't work in birds because eggs can't be removed and implanted. Instead, the company is trying to bulk-grow embryonic stem cells taken from fertilized eggs as soon as they're laid. "The trick is to culture the cells without them starting to distinguish, so they remain pluripotent. " says Fitzgerald. Using a long-established technique, these donor cells will then be injected into the embryo of a freshly laid, fertilized recipient egg, forming a chick that is a "chimera". Strictly speaking, a chimera isn't a clone, because it contains cells from both donor and recipient. But Fitzgerald says it will be enough if, 95 percent of a chicken's body develops from donor cells. "In the poultry world, it doesn't matter if it's not 100 percent. " he says. Another challenge for Origen is to scale up production. To do this, it has teamed up with Embrex, which produces machines that can inject vaccines into up to 50,000 eggs an hour. Embrex is now trying to modify the machines to locate the embryo and inject the cells into precisely the right spot without killing it. In future, Origen imagines freezing stem cells from different strains of chicken. If orders come in for a particular strain, millions of eggs could be produced in months or even weeks. At present, maintaining all the varieties the market might call for is too expensive for breeders, and it takes years to bread enough chickens to produce the billions of eggs that farmers need.

单选题Sex Change Surgery Guidelines Drafted China is set to (51) its first clinical guideline on sex-change surgery, according to a notice put on the website of the Ministry of Health yesterday. The ministry is now soliciting public and professional opinions on the draft guideline. The coming guideline aims to regulate and standardize sex reassignment surgery, part of a treatment for gender identity disorder in transsexuals. Experts (52) nearly 2,000 Chinese have undergone sex-change surgery while 100,000 to 400,000 are still considering it. However, no official number is available. In the draft, the MOH sets (53) criteria for both surgical candidates and medical institutions. Candidates for the surgery must be older than 20 and single, the draft guideline said. They are also required to prove a persistent desire for a sex change, to live for at least five consecutive years full-time in the new gender role, and to engage (54) mental therapy for at least one year. Before surgery can take place, a candidate must receive a recommendation for the operation from a (55) after an appropriate series of therapy sessions. Also, several legal requirements (56) be met before the procedure. The candidate must provide proof from police that he or she has does not have any criminal offenses in the past. Police must also agree to change the sex status on the identity card of the (57) receiver before the operation can, take (58) . The advent of such a guideline (59) to show that the government is concerned (60) the needs of a relatively small (61) of people who want to change sex. But doctors also warn that all stakeholders, including the hospital and prospective receivers, should be highly cautious about this surgery. The operation is more than a medical procedure due (62) its huge social and legal consequences. Doctors should make it clear to those (63) sex-change surgeries that the option always remains to continue to live in the original role. The guideline requires surgeons to tell patients about other options (64) hormone therapy. They are also required to explain the risks involved, and underlying social barriers including discrimination, and administrative recognition and approval. For the candidates, the surgery itself is not the big issue (65) the long run. The real issue is the kind of life he or she will have to lead afterward.
