听力原文: When a sleepy driver has trouble with keeping his eyes on the road and gets too close to another car, an alarm sound will warn the driven If nothing is done, the car will automatically come to a stop and in this way prevent an accident. This is a new device which will soon be tested in an experimental car in Japan (33) . The computer warning system keeps track of a driver's condition by monitoring his heartbeat with signals transmitted from a band around his wrist (35) . The wrist hand records the drivers' pulse which measures the heartbeat. Each pulse in the wrist sends a signal to the computer. By analyzing the pulse rate, the computer can determine whether a driver is drunk, sleeping or ill. Devices in other parts of the car can also tell the computer if the car is too close to another vehicle or is moving dangerously. The computer will sound the alarm when a problem arises, and will automatically stop the car if the driver ignores the warning (34) .

听力原文: 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 the study say giving aspirin to patients soon after the operation could save thousands of lives (26) . 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 to 15 percent of these heart operations end in death or damage to the heart or other organs. The new study shows the 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 (27) . However, the doctors warned that people who have stomach bleeding or other bad reactions from aspirin should not take it after heart surgery (28) .
