[简答题]A study presented last week at the American Heart Association meeting suggests that mental relaxation produced by meditation may have physiological benefits, at least in the case of people with established coronary artery disease. Researchers followed about 200 high-risk patients for an average of five years. Among the 100 who meditated, there were 20 heart attacks, strokes and deaths; in the comparison group, there were 32. (57) The meditators tended to remain disease-free longer and also reduced their blood pressure. "We found reduced blood pressure that was significant--that was probably one important mediator," said Dr. Robert Schneider, director of the Institute for Natural Medicine and Prevention in Fairfield, Iowa, who presented the findings. The study was conducted at the Medical College of Wisconsin in Milwaukee, in collaboration with the institute. Dr. Schneider suggested that (58) the stress reduction produced by the meditation could cause changes in the br
[填空题]A recent study, published in last week’s Journal of the American Medical Association, offers a picture of how risky it is to get a lift from a teenage driver. Indeed, a 16-year-old driver with three or more passengers is three times as likely to have a (47) accident as a teenager driving alone. By (48) , the risk of death for drivers between 30 and 59 decreases with each additional passenger.
The authors also found that the death rates for teenage drivers increased (49) after 10 p.m., and especially after midnight. With (50) in the car, the driver was even more likely to die in a late-night accident.
Robert Foss, a scientist at the University of North Carolina Highway Safety Research Center, says the higher death rates for teenage drivers have less to do with "really stupid behavior" than with just a lack of driving (51) .
