单选题Where Did All the Ships Go The Bermuda Triangle is one of the greatest mysteries of the sea. In this triangle area between Florida, Puerto Rico and Bermuda in Atlantic, ships and airplanes seem to disappear more of ten than in other pans of the ocean. And they do so without leaving any sign of all accident or any dead bodies. It is said that Christopher Columbus was the first person to record strange happenings in the area. His compass stopped working, a flame came down from the sky, and a wave 100 to 200 feet high carried his ship about a mile away. The most famous disappearance in the Bermuda Triangle was the U. S. Naval Air Flight 19. On December 5, 1945, five bomber planes carrying 14 men took offon a training mission from the Florida coast. Later that day, all communications with Flight 19 were lost. They just disappeared without a trace. The next morning, 242 planes and 19 ships took part in the largest air-sea search in history. But they found nothing. Some people blame the disappearances on supernatural forces. It is suggested the missing ships and planes were either transported to other times and places, kidnapped by aliens or attacked by sea creatures. There are also natural explanations, though. The U. S. Navy says that the Bermuda triangle is one of two places on earth where a magnetic compass points towards true north instead of magnetic north. Therefore, planes and ships can lose their way if they don't make adjustments. The area also has changing weather and is known for its high waves. Storms can turn up suddenly and destroy a plane or ship. Fast currents could then sweep away any trace of an accident.

单选题 The Emic and Etic Approaches Researchers who are unfamiliar with the cultural and ethnic groups they are studying must take extra precautions to shed any biases they bring with them from their own culture. For example, they must make sure they construct measures that are meaningful for each of the cultural or ethnic minority groups being studied. In conducting research on cultural and ethnic minority issues, investigators distinguish between the emic approach and the etic approach. In the emic approach, the goal is to describe behavior in one culture or ethnic group in terms that are meaningful and important to the people in that culture or ethnic group, without regard to other cultures or ethnic groups. In the etic approach, the goal is to describe behavior so that generalizations can be made across cultures. If researchers construct a questionnaire in an emic fashion, their concern is only that the questions are meaningful to the particular culture or ethnic group being studied. If, however, the researchers construct a questionnaire in an etic fashion, they want to include questions that reflect concepts familiar to all cultures involved. How might the emic and etic approaches be reflected in the study of family processes? In the emic approach, the researchers might choose to focus only on middle-class White families, without regard to whether the information obtained in the study can be generalized or is appropriate for ethnic minority groups. In a subsequent study, the researchers may decide to adopt an etic approach by studying not only middle-class White families, but also lower-income White families, Black American families, Spanish American families, and Asian American families. In studying ethnic minority families, the researchers would likely discover that the extended family is more frequently a support system in ethnic minority families than in White American families. If so, the emic approach would reveal a more different pattern of family interaction than would the etic approach, documenting that research with middle class White families cannot always be generalized to all ethnic groups.

单选题The Threat to Kiribati The people of Kiribati are afraid that one day in the not-too-distant future, their country will disappear from the face of the earth literally. This year, the Pacific island nation has been flooded by sudden high tide several times. These tides, which swept across the island and destroyed houses, came when there was neither wind nor rain. "This never happened before," say the older citizens of Kiribati. What is causing these mysterious high tides? The answer may well be global warming. When fuels like oil and coal are being burned, pollutants (污染物) are released; these pollutants trap heat in the earth"s atmosphere. Warmer temperatures cause water to expand and also create more water by melting glaciers (冰川) and polar (极地的) ice caps. If the trend continues, the scientists say, many countries will suffer. Bangladesh, for example, might lose one-fifth of its land. The coral (珊瑚) island nations of the Pacific, like Kiribati and the Marshall Islands, however, would face an even worse fate—they would be swallowed by the sea. The loss of these coral islands would be everyone"s loss. Coral formations are home to more species than any other place on earth. The people of these nations feel frustrated. The sea, on which their economies have always been based, is suddenly threatening their existence. They don"t have the money for expensive technological solutions like seawalls. And they have no control over the pollutants, which are being released mainly by activities in large industrialized countries. All they can do is to hope that industrialized countries will take steps to reduce pollution.

单选题Stop Eating Too Much "Clean your plate!" and "Be a member of the clean-plate club!" Just about every kid in the US has heard this from a parent or grandparent. Often, it's accompanied by an appeal: "Just think about those starving orphans (孤儿) in Africa! " Sure, we should be grateful for every bite of food. Unfortunately, many people in the US take too many bites. Instead of staying "clean the plate", perhaps we should save some food for tomorrow. According to news reports, US restaurants are partly to blame for the growing bellies (肚子). A waiter puts a plate of food in front of each customer, with two to four times the amount recommended by the government, according to a USA Today story. Americans traditionally associate quantity with value and most restaurants try to give them that. They prefer to have customers complain about too much food rather than too little. Barbara Rolls, a nutrition (营养) professor at Pennsylvania State University, told USA Today that restaurant portion sizes began to grow in the 1970s, the same time that the American waistline (腰围) began to expand. Health experts have tried to get many restaurants to serve smaller portions. Now, apparently, some customers are calling for this too. The restaurant industry trade magazine QSR reported last month that 57 percent of more than 4,000 people surveyed believed restaurants served portions that were too large; 23 percent had no opinion; 20 percent disagreed. But a closer look at the survey indicates that many Americans who can't afford fine dining still prefer large portions. Seventy percent of those earning at least ＄150,000 per year prefer smaller portions; but only 45 percent of those earning less than ＄25,000 want smaller. It's not that working class Americans don't want to eat healthy. It's just that, after long hours at low-paying jobs, getting less on their plate hardly seems like a good deal. They live from paycheck (薪金支票) to paycheck, happy to save a little money for next year'sChristmas presents.

单选题How Men Face the Fat Problem It is a pleasure to see men of a certain age worrying about their weight. Listening to them is not such a pleasure. Because the men are new at the game, they don't hesitate to discuss the fat problem incessantly. However, women of the same age do not discuss the fat problem, especially not in mixed company. They prefer to face the problem with quiet dignity. Discussing the problem might only draw attention to some stray body part that may be successfully tucked away under an article of clothing. The age at which a man begins to explore the fat problem can vary. The actual problem can manifest itself in the early 30's, but broad-range discussion usually starts later. There are early nonverbal symptoms. I've watched the rugged journalist who shares my apartment sneak by with a Diet Coke. His shirts are no longer neatly tucked in to display a trim waist. Recently he has begun to verbalize his anxiety. He tells me, with a sheepish grin, that he is taking his suits to Chinatown to have them "tailored." Still-older men have lost their dignity and rattle on unabashedly. Often, wives and children play important roles in their fat-inspection rituals. Take my oldest brother, a former college football player. His daughter says that several times a day he will stand at attention and call out, "Fat, medium or thin?" She knows the correct answer: medium. Thin would be an obvious stretch, and fat may not get her that new video. According to his wife, he stands in front of the mirror in the morning (before the day's meals take their toll), puts his hands behind his head and lurches into a side bend, then clutches the roll that has developed and says, "Am I getting fatter?" His wife is expected to answer, "You look like you may have lost a few pounds." And then there are the ex-husbands, a pitiful group. They are extremely vocal. When I go to the movies with one, he confides that he is suffering from great hunger because he is dieting. He hasn't eaten since the pancakes and sausages he wolfed down that morning. He pauses in his monologue while he buys his popcorn. After the movie, we sprint to a restaurant, where he again pauses to devour a basket of bread. Before he orders his chaste salad and soup, he grows plaintive. Do I think he's fat?

单选题{{B}}第二篇{{/B}} {{B}} Attitude Towards New Technology{{/B}} Telecommunications is just one of the means by which people communicate and, such as, we need to look at telecommunications and any other communications technologies within the wider context of human communication activity. Early findings show that many people are uneasy and even fearful of information technology. They seldom use it or simply avoid it. To obtain this type of data we have spent time with individuals, watching how they communicate, where they get confused, what they don't understand, and the many mistakes they make. You can do this type of research yourself in an informal way. Just watch someone at the desk next to you trying to use a phone or trying to fill in a form. What you will quickly notice about people on the phone is that they use very few of the buttons available on the keypad(键区) ,and they get quite anxious if they have to use any buttons outside their normal ones. Most will not use the instruction book, and those that do will not necessarily have a rewarding experience. Watch someone fill out a form, such as an application form or a tax form, and you will see a similar pattern of distressed behaviour. The simple fact we can all observe from how people use these ordinary instruments of everyday communication is how messy, uncertain and confusing the experience can be. From getting up in the morning until you go to bed at night, you can always encounter people getting confused over the use of new technology. Even watching television, which for many provides an antidote(解药) to the daily confusion, is itself filled with a kind of low level confusion. For example, if you ring people up five minutes after the evening news has finished and ask them what the news was about, many cannot remember, and those who do remember get some of it wrong. One of the reasons why this obvious confusion has gone unnoticed is that "communication As a word we associate with success, and therefore we expect the process to work effectively most of the time. To suggest otherwise is to. challenge one of our society's most deeply held beliefs.

单选题下面有3篇短文，每篇短文后有5道题，每题后面有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}} Silence Please If there is one group of workers across the Western world who will be glad that Christmas is over, that group is shop workers. It is not that they like to complain. They realize that they are going to be rushed off their feet at Christmas. They know that their employers need happy customers to make their profits that pay their wages. But there is one thing about working in a shop over Christmas that is too bad to tolerate. That thing is music. These days, all shops and many offices have what is known as "Piped music" or "muzak" playing for all the hours that they are open. Muzak has an odd history. During the 1940s, music was played to cows as part of a scientific experiment. It was found that cows which listened to simple, happy music produced more milk. Perhaps workers and customers who listened to simple, happy music would be more productive and spend more money. In fact, nobody knows what effect playing muzak in shops has on profits. It is simply something that everybody does. But we are learning more about the effect of constantly repeated hearings of songs on the people who have to hear them all the time. Research shows that repeated hearings of complex pieces of music bring greater enjoyment before becoming tiresome. And that point come much sooner with simple songs. "That's especially the case with tunes that are already familiar. Once that tipping point is reached, repeated listening become unpleasant, says Professor John Sloboda of UK's Keele University's music psychology group. "And the less control you have over what you hear, the less you like it. That's why police forces in the US often try and resolve hostage situations by playing pop songs over and over again at high volume. Eventually, it becomes too much for the criminals to stand and they give up. The problem gets particularly bad at Christmas, when the muzak consists entirely of the same few festive tunes played over and over again. What makes it worse for the shop workers is that they already know these runes. They get bored very quickly. Then they get irritated. Then they get angry. Shop workers in Austria recently threatened to go on strike for the right to silence. "Shop workers can't escape the Christmas muzak. They feel as if they are terrorized all day. Especially ‘Jingle Bells’. It arouses aggressive feelings," said Gottfried Rieser, of the Austrian shop worker's union. It is not just shop workers who complain. A survey this year by UK recruitment website Retailchoice. com found that Christmas is not only the most testing time for shop workers, but that almost half had complaints from customers about muzak. And the British Royal National Institute for the Deaf estimates that some stores play Jingle Bells 300 times each year. "That's acoustic torture, says Nigel Rodgers of Pipedown. A group against muzak. "It's not loud but the repetitive nature causes psychological stress. " The group wants the government to legislate against unwanted music in stores, hospitals, airports, swimming pools and other public places, claiming it raises the blood pressure and depresses the immune system. Perhaps groups like Pipedown don't really have much to complain about. After all, surely the real point is that people have money to spend. Why complain about a bit of music?
