Choose the best one and mark your answer on the ANSWER SHEET with a single line through the center.{{B}}Passage One{{/B}} "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 a few too many bites. Instead of saying "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 serve large portions to stand apart from competitors and to give the customers value. They prefer to have customers complain about too much food rather than too little. Barbara Rolls, a nutrition 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 began to expand. Health experts have tried to get many restaurants to serve smaller portions. Now, apparently, some customers are calling for this too. A restaurant industry trade magazine reported last month that 57 percent of more than 4 000 people surveyed believed restaurants serve portions that are 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 to paycheck, happy to save a little money for next year's Christmas presents.

单选题Since we are social beings, the quality of our lives depends in large measure on our interpersonal relationships. One strength of the human condition is our tendency to give and receive support from one another under stressful circumstances. Social support consists of the exchange of resources among people based on their interpersonal ties. Those of us with strong support systems appear better able to cope with major life changes and daily hassles (困难). People with strong social ties live longer and have better health than those without such ties. Studies over a range of illnesses, from depression to heart disease, reveal that the presence of social support helps people fend off (挡开) illness, and the absence of such support makes poor health more likely. Social support cushions stress in a number of ways. First, friends, relatives, and co-workers may let us know that they value us. Our self-respect is strengthened when we feel accepted by others despite our faults and difficulties. Second, other people often provide us with informational support. They help us to define and understand our problems and find solutions to them. Third, we typically find social companionship supportive. Engaging in leisure-time activities with others helps us to meet our social needs while at the same time distracting (转移……注意力) us from our worries and troubles. Finally, other people may give us instrumental support—financial aid, material resources, and needed services—that reduces stress by helping us resolve and cope with our problems.

单选题{{B}}Passage Four{{/B}} Global climate change, often seen as a process stretching over thousands of years, could in fact occur abruptly and unexpectedly-quickly pushing up temperatures by as much as 18 degrees Fahrenheit and wreaking havoc(大破坏，浩劫) on human society, scientists warned on Wednesday. "Climate change is not always smooth. Sometimes it is abrupt," said Richard Alley, a climate expert at Pennsylvania State University and lead author of a new National Academy of Sciences report on the threat of rapid climatic shifts. "If you have a very large, abrupt change, a lot of people and a lot of ecosystems are going to notice," he said．"The bigger and faster it is, the harder it will be to deal with." The new National Academy of Sciences report, released this week, warns that gradual global warming coupled with other human impacts on the environment could "trip the switch" for sudden climate change. At the American Geophysical Union meeting on Wednesday, Alley and other environmental scientists said the geological evidence indicated that such rapid climate shifts had occurred frequently in the past—moving temperatures drastically in the space of just a few decades. "This can happen in less than a human generation, and then it will persist for thousands of years," said David Battisti, an atmospheric scientist at the University of Washington. The most immediate dangers posed by abrupt climate change range are devastating droughts and floods which could seriously affect both water supply and agriculture across vast stretches of the planet. Longer term impacts could include changes in the basic systems which determine regional global temperatures. Scientists believe that the Gulf Stream, a current (水流) of warm Atlantic water which now keeps much of Northern Europe temperate, could theoretically reverse direction if enough cool fresh water runs into the north Atlantic from melting ice, a change that would quickly impact European weather.

单选题A few years ago, in their search for ways to sell more goods, advertising men hit on a new and controversial gimmick. It is a silent, invisible commercial that, the ad men claim, can be rushed past the consumer's conscious mind and planted in his subconscious—and without the consumer's knowledge. Developed by James Vicary, a research man who studies what makes people buy, this technique relies on the psychological principle of subliminal perception. Scientists tell us that many of the sights coming to or eyes are not consciously "seen" . We select only a few for conscious "seeing" and ignore the rest. Actually the discarded impressions are recorded in the brain though they are below the threshold of consciousness. There's little doubt in Vicary's mind as to the subliminal ad's effectiveness. His proof can be summed up in just two words: sales increase. In an unidentified movie house not so long ago, unknown audiences saw a curious film program. At the same time, on the same screen on which the film hero was courting the heroine a subliminal projector was flashing its invisible commercials. "Get popcorn," ordered the commercial for a reported one three-thousandths of a second every five seconds. It announced "Coca-Cola" at the same speed and frequency to other audiences. At the end of a six weeks trial, popcorn sales had gone up 57 percent, Coke sales 18 percent. Experimental Films. Inc, says the technique is not new. It began research on subliminal perception in 1954. Experimental Films stresses that its equipment was designed for helping problematic students and treating the mentally ill. At NYU two doctors showed twenty women the projected image of an expressionless face. They told the subjects to watch the face for some change of expression. Then they flashed the word angry on the screen at subliminal speeds. Now the women thought the face looked unpleasant. When the word happy was flashed on the screen instead, the subjects thought the woman's facial expression looked much more pleasant. Subliminal techniques, its promoters believe, are good for more than selling popcorn. Perhaps the process can even be used to sell political candidates, by leaving a favorable impression of the candidate in the minds of the electorates subliminally. How convincing are these invisible commercials? Skeptical psychologists answer that they aren't anywhere near as effective as the ad men would like to think they are. Nothing has been proven yet scientifically, says a prominent research man.
