单选题 When we conduct foreign trade, the importance of understanding the language of a country cannot be underestimated. The successful marketer must achieve export requires a thorough understanding of the language as well as the ability to speak it. Those who deal with advertising should be concerned less with obvious differences between languages and more with the exact meanings expressed. A dictionary translation is not the same as an idiomatic interpretation, and seldom will the dictionary translation meet the needs. A national producer of soft drinks had the company's brand name impressed in Chinese characters which were phonetically (按照发音地) accurate. It was discovered later, however, that the translation's literal meaning was "female horse fattened with wax", hardly the image the company sought to describe. So carelessly translated advertising statements not only lose their intended meaning but can suggest something very different including something offensive or ridiculous. Sometimes, what was translated was not an image the companies had in mind for their products. Many people believe that to fully appreciate the true meaning of a language it is necessary to hve with the language for years. Whether or not this is the case, foreign marketers should never take it for granted that they are affectively communicating in another language.

单选题Imagine eating everything delicious you want—with none of the fat. That would be great, wouldn"t it? New "fake fat" products appeared on store shelves in the United States recently, but not everyone is happy about it Makers of the products, which contain a compound called olestra, say food manufacturers can now eliminate fat from certain foods. Critics, however, say the new compound can rob the body of essential vitamins and nutrients (营养物) and can also cause unpleasant side effects in some people. So it"s up to decide whether the new fat-free products taste good enough to keep eating. Chemists discovered olestra in the late 1960s, when they were searching for a fat that could be digested by infants more easily. Instead of finding the desired fat, the researchers created a fat that can"t be digested at all. Normally, special chemicals in the intestines (肠) "grab" molecules of regular fat and break them down so they can be used by the body. A molecule of regular fat is made up of three molecules of substances called fatty acids. The fatty acids are absorbed by the intestines and bring with them the essential vitamins A, D, E, and K. When fat molecules are present in the intestines with any of those vitamins, the vitamins attach to the molecules and are carried into the bloodstream. Olestra, which is made from six to eight molecules of fatty acids, is too large for the intestines to absorb. It just slides through the intestines without being broken down. Manufacturers say it"s that ability to slide unchanged through the intestines that makes olestra so valuable as a fat substitute. It provides consumers with the taste of regular fat without any bad effects on the body. But critics say olestra can prevent vitamins A, D, E, and K from being absorbed. It can also prevent the absorption of carotenoids (类胡萝卜素 ), compounds that may reduce the risk of cancer, heart disease, etc. Manufacturers are adding vitamins A, D， E, and K as well as carotenoids to their products now. Even so, some nutritionists are still concerned that people might eat unlimited amounts of food made with the fat substitute without worrying about how many calories they are consuming. (381 words)

单选题{{B}}Passage Three{{/B}} Young people in the United States have a wide variety of inte-rests apart from their school work. As children, both boys and girls play many of the same games. They swim, play baseball and basketball, go boating and camping, and have fun in many kinds of sports and outdoor activities. Numerous youth organizations give young people a chance to develop and broaden their interests, and to gain experience in working with others. Among these groups are the Boy Scouts, which serves more than four million boys, the Girl Scouts, with nearly three million girls, and the Boys' Club of America, with over one million participants. These and other groups are guided by adults who volunteer their services. Civic, cultural and religious groups also sponsor special programs for young people. In farm areas, boys and girls learn to work together in agriculture, homemaking and citizenship activities through more than 158 360 clubs which have about 4 420 932 members. In these clubs youths compete for prizes in raising farm animals and growing crops. Secondary schools offer students a wide variety of activities to develop talents and skills. There are clubs for photography, music, theater, art, stamp collecting, natural science and debating. Often schools have orchestras, bands and singing groups as well as a variety of competitive sports for boys and girls. Most schools and colleges have some form of student government with election to choose class representatives. These elected officers speak for their fellow students at student council meetings with teachers and school officials. They also organize social activities and take part in such community projects as raising money for public welfare. Many young people hold part-time jobs after school hours. Thousands earn money delivering newspapers or helping care for infants and young children in private homes. Later, when they go to college, many youths continue to work part-time at a variety of jobs to help pay their expenses. For several weeks during the summer vacation, about five million school-age children go to camps where they get plenty of recreational activity and learn various skills.
