听力原文: [29] Moods, say the experts, are feelings that are likely to be fixed, having effects on one's outlook for hours, days, weeks or even years. That's great if your mood is a pleasant one, but it will be a problem if you are sad, anxious, angry or simply lonely.
Perhaps the best way to deal with such moods is to talk them out; sometimes, though, there is no one to listen. Modem pharmacy offers a lot of anti-anxiety drugs. [30]What many people don't realize, however, is that scientists have discovered the effectiveness of several non-drag methods to make you free from an unwanted mood. These can be just as useful as drags, and have the added benefit of being non-poisonous. So next time you feel out of sorts, don't head for the drug store—try the following method.
[30] Of all the mood-changing self-help techniques, aerobic exercise seems to be the best cure for a bad mood. "If you could keep the exercise, you'd be in high spirits," says Kathryn Lance, author of Running for Health and Beautv. Researchers have explained biochemical and various other changes that make exercise seem preferable to drags as a mood-raiser. Physical work such as housework, however, does little. [31] The key is aerobic exercise—running, cycling, walking, swimming, or other repetitive activities that increase the heart rate and circulation, and improve the consumption of oxygen. You may do them for at least 20 minutes a time, three to five times a week.

Some plan to use the findings to support calls for closing the nuclear reactors at Indian Point(A nuclear power station is U. S. A. ), the plant closest to New York City. But federal officials, some radiation experts and representatives of the nuclear plants and that minute, occasional releases from such plants were much lower than natural radiation levels,
The new statistical study, which is being published in Archives of Environmental Health, was conducted by a group of scientists who for many years have intended to show a link between mortality and illness and low levels of radiation from power plants, bomb tests and other sources.
The study said the infant death rate in communities for two years before the plant shutdowns averaged 8.44 deaths per l, 000 births and, when all the mortality data for two years after the plant shutdowns were combined, the infant mortality rate dropped to 7.01 per l, 000 births. The difference was statistically significant, the authors said, and the drop was greater than the general drop in infant death rates around the country in recent years.
Joseph Mangano, a public health statistician and the national coordinator for the group, said a statistical link does not prove a cause and effect, but points to the need for more work. He said," The list is literally endless. This doesn't mean we've proved anything beyond a shadow of a doubt, but what I will say is we really need to do more follow-up."
The new study was conducted by______.
A.the government
B.radiation experts
C.antinuclear campaigners
D.public health statisticians
