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 American scientists are developing maps that can identify areas of future flooding. The maps also may help scientists estimate the possibility of extremely dry weather and severe storms. Tom Jackson of the United States Department of Agriculture prepared the map after the April flood. He used information provided by satellites in Earth orbit. The maps are produced from dish receivers on the satellites. Each dish receiver measures the wetness of the soil by capturing the natural release of microwave radiation from the soil. The receivers turn rapidly. This provides complete coverage of each area the satellite passes over. Mr. Jackson and other scientists have tested Aqua''s equipment in airplanes and satellites flying over several states. The scientists used the tests to develop ways to change the information gathered into maps. Mr. Jackson now plans to compare the microwave dish receiver findings with information from tests on Earth''s soil. He will use instruments at Agricultural Research Service centers in four states. He also will study information provided by forty ground observation centers across the country. American scientists are developing maps that can identify areas of future flooding.

听力题 Many people think that nothing happens when they sleep. Doctors have studied sleep for many years. They think that a lot happens when people sleep. Doctors say that people have five kinds, or stages, of sleep. People may go through each stage about every 10 minutes. During the first two stages, you sleep lightly. That is, if someone calls you or puts his hand on you, you wake up quickly. Your body rests quietly, you breathe more slowly than when you are awake. Your heart beats slowly. During stages three and four, you sleep deeply. That is, if someone puts his hand on you, you don’t wake up. Your heart beats more slowly than that in stages one and two. You don’t hear sounds. Lights don’t wake you up. The last stage of sleep is called REM (Rapid Eye Movement). During REM sleep you breathe faster, and your heart beats faster than that in stages one through four. Your eyes move under your eyelids. All of this happens because you are dreaming. Doctors say that everyone dreams. Some dreams are short; some dreams are long. Some people are good at remembering their dreams; others forget theirs. Many people think that nothing happens when they sleep. Doctors have studied sleep for many years.

听力题 A team of scientists recently began a project to measure the effects of loud noises on sea animals. If the sounds don''t harm the animals, then the researchers can go ahead with a plan to transmit sound waves through the Pacific Ocean to take the earth''s temperature. Sound travels faster through warm water than cold water. By analyzing the speed of sound through the ocean over a time, the scientists will be able to determine if our planet is warming up. The experiment was nearly cancelled more than a year ago because environmental groups feared that the sound will confuse or harm the sea-animals. So, scientists are conducting tests on the animals first. The researchers lowered a loud speaker that emits low frequency sound about 1,000 meters beneath the ocean. Scientists at the site transmit sound waves into the ocean. Radio transmitters attached to some of the sea-animals help the researchers keep track of the animals'' movements. If sea-animals are distressed by me sounds, they would swim away from the speakers. So far, there aren''t any signs that the animals are being harmed. Researchers at the site noticed that large numbers of sea-animals swim near the speaker whether it was turned on or off, but it is still too soon to know for sure, the scientists admit. The test will continue through September. "If all goes well," they say, "we can begin measuring temperature changes on our planet."

听力题 Last summer I spent a two-week vacation in Miami Beach, Florida. My roommate and I flew to Miami from New York in three hours. It was the first time for both of us, and we went there because the rates are lower out of season. We stayed at an air-conditioned luxury hotel on the beach. We slept late every morning and then had breakfast outdoors near the pool. When the weather was not too hot, we went sightseeing in the morning. We visited the Seaquarium, the campus of the University of Miami, and the Everglades. In the afternoons, we went swimming in the ocean or the pool, lay in the sun, or went water-skiing. After dinner in the evening, we went dancing in a discotheque or watched the entertainment in the nightclubs. The weather was very good every day, and the holiday went by too quickly. We were both sorry when the vacation ended. Last summer I spent a two-week vacation in Miami Beach, Florida. My roommate and I flew to Miami from New York in three hours.
