听力题 It has been estimated that about twenty thousand words are in full use in English today, and if this estimate is correct, it brings us up to Shakespeare''s total. Of these, one-fifth, or about four thousand, are said to be of Anglo -Saxon origin, and three-fifths, or about twelve thousand, are of Latin, Greek and French origin. This, of course, does not mean that our everyday conversation consists chiefly of foreign words, according to one estimate, one-fourth of all our spoken language consists of repetition of the words: and, be, have, it, of, the, to , will, you, I, a, on, that, and is. Another analysis of five million words written by adults reveals that our ten most frequently used words are I, the, and, to, of, in, we, for, you, and a. Both lists consist, without exception, of native words. If we go into literary usage, we find that words of the Bible are ninety-four percent native, Shakespeare''s ninety percent, Tennyson''s eighty-eight percent, Milton''s eighty-one percent, and Samuel Johnson''s seventy-two percent. Only in present-day technical writings do we find the foreign element climbing to forty percent.

听力题 A new study reports the common drug aspirin greatly reduces life threatening problems after an operation to replace blocked blood vessels to the heart. More than 800,000 people around the world have this heart surgery each year. The doctors who carried out this study say giving aspirin to patients soon after the operation could save thousands of lives. People usually take aspirin to control pain and reduce high body temperature. Doctors also advise some people to take aspirin to help prevent heart attacks. About 10-15 percent of these heart operations end in death or damage to the heart or other organs. The new study shows that even a small amount of aspirin reduced such threats. The doctors said the chance of death for patients who took aspirin would fall by 67%. They claimed this was true if the aspirin was given within 48 hours of the operation. The doctors believe aspirin helps heart surgery patients because it can prevent blood from thickening and blood vessels from being blocked. However, the doctors warned that people who have stomach bleeding or other bad reactions from aspirin should not take it after heart surgery.

听力题 When Iraqi troops blew up hundreds of Kuwait''s oil well at the end of the Gulf War, scientists feared an environmental disaster. Would black powder in the smoke from the fires circle the globe and block out the sun? Many said no way. Rain would wash the black power from the atmosphere. But in America, air-sampling balloons have detected high concentrations of particles similar to those collected in Kuwait. Now that the fires are out, scientists are turning their attention to yet another threat — the oil that didn''t catch fire. It has formed huge lakes in the Kuwaiti desert. They trap insects and birds and poison a variety of other desert animals and plants. The only good news is that the oil lakes have not affected the underground water resources. So far, the oil has not been absorbed because of the hard sand just below the surface. Nothing, however, stops the oil from evaporating. The resulting poisonous gases are choking nearby residents. Officials are trying to organize a quick cleanup but they are not sure how to do it. One possibility is to burn the oil. Get those powder detectors ready!

听力题Well, good morning

听力题 The university was asking students to select summer social topics for projects to undertake. Ding Ling proposed the idea of accessing the AIDS town, and university officials approved the project. After contacting officials at the institution, Ding Ling got on the train for her hometown with fellow student Zhou Wang on July 20. On July 21, when the two girls finished breakfast in a small restaurant after they had just arrived at the town, the keeper told Ding in a low voice that the man who ate breakfast beside her was an AIDS patient, which surprised the two. AIDS was all around them. AIDS patients in their hometown live just as anyone else does. They do not stay in any one centralized place to receive treatment. If they need help, they go to the medical institution just like any other patient world. There are no divorce cases in the town because of HIV infections, and local residents do not discriminate the HIV carriers, the two girls said. The students said their most unforgettable day was July 16, when they had the lunch with a female AIDS patient whose husband knew of her illness before they were married. But her husband still resolutely loved her and took on the responsibility of looking after his wife. After the pair returned to school, many friends urged them to go to the hospital to check whether they had been infected or not. They just smiled, declining to be checked. HIV can only be spread by sexual contact or blood-to -blood contact. The biggest wish for Ding is to see an 8-year-old child, Huan Huan, who was infected by her mother, during upcoming Spring Festival. She hopes to bring the little girl some clothes and food, and to take along a camera to record happy moments in the lives of AIDS patients.

M: That''s it... uh ... then what? W: Then all you have to do is taste each sample and describe where each flavor seems most intense. M: Is that hard? W: Not really.
