Unit 6 Shaping and Reshaping Personality (II)

Tape-script: Part I

A

1. Tea contains natural chemicals. These chemicals block the action of some substances produced in the bodies that cause cancer. Tea contains the same substances in fruits and vegetables. Drinking tea could protect people's health.

2. Cigarette smokers of any age reduce their risk of developing lung cancer when they stop smoking. It is never too late to stop smoking.

3. Walking has a good effect on the heart because it reduces blood pressure, blood sugar and blood cholesterol level. It is never too late to start exercising.

4. Vitamins are necessary for good health. However, extremely large amounts of some vitamins may cause health problems. It is far better to get vitamins from eating fresh, natural food than from taking vitamin pills.

5. Laughter is one of the most wonderful releases. It releases the chemical that is life-enhancing and life-elongating. It heals wounds and promotes a healthier being.

B. Tapescript:

The United States government's Office of Research on Women's Health is observing its tenth anniversary. During those ten years it has made important discoveries about differences in the health of men and women. Studies organized by the Office of Research on Women's Health have shown that differences between men and women can influence medical treatment.

For example, researchers learned that men and women can react differently to a heart attack. Men usually have chest pain. But women may not. Instead, they may suffer pain in the abdomen. They also may have stomach sickness and feel very tired. Women may not recognize that they are having a heart attack.

Research also has shown that the brains of men and women use the chemical serotonin differently. Serotonin helps prevent the condition of continued severe sadness called depression. Men's brains use serotonin much more effectively than women's brains do. This may help explain why women suffer depression two or three times more often than men do.

Other research shows that alcohol affects men and women differently. Men and women in one experiment drank the same amount of alcoholic drinks. Then researchers measured their blood for alcohol levels. The women had higher levels of alcohol in their blood. Women produce less of a substance called gastric alcohol dehydrogenase. This causes them to break down alcohol more slowly than men.
