| 第4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 consumers 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 vitaminsA,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 vitaminsA,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 vitaminsA,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. We learn from the passage that olestra is a substance that ______. A、contains plenty of nutrients B、makes foods fat-free while keeping them delicious C、renders foods calorie-free while retaining their vitamins D、makes foods easily digestible |

| 第10题： A、study of more than five million books, both fiction and non-fiction, has found a marked decline in the use of emotional words over time. The researchers form the University ofBristol used Google Ngram Viewer, a facility for finding the frequency of terms in scanned books, to search for more than 600 particular words identified as representing anger, dislike, fear, joy, sadness and surprise.They found that almost all of the categories (类别) showed a drop in these “mood words” over time. Only in the category of fear was there an increase in usage.“It is a steady and continuous decrease,” saidDrAlbertoAcerbi. He assumed that the result might be explained by a change in the position occupied by literature, in a crowded media landscape. “One thing could be that in parallel to books the 20th century saw the start of other medi A、Maybe these media—movies, radio, drama—had more emotional content than books.” Although both joy and sadness followed the general downwards trend, the research, published in the journal PLOS One, found that they also exhibited another interesting behaviour：the ratio (比率) between the two varied greatly, apparently mirroring historical events. During the Roaring Twenties the joy-to-sadness ratio reached a peak that would not occur again until before the recent financial crash.But the ratio plunged at the height of the Second World War. Nevertheless, the researchers held a reserved opinion about their claim that their result reflected wider social trends. In the paper, they even argue that the reverse could be true.“It has been suggested, for example, that it was the suppression (压抑) of desire in ordinaryElizabethanEnglish life that increased demand for writing ‘filled with romance and sex’… perhaps,” they conclude, “songs and books may not reflect the real population any more than catwalk models reflect the average body.”(Note：Answer the questions or complete the statements in NO MORE、THAN TEN WORDS.) While the researchers found some changes in the use of “mood words” in books, they were not sure that _______________. |
