[单项选择]Passage Four
Public health experts have long been skeptical about the beneficial effect of pets on the health of their owners. After all, dogs bite and pass on parasites, and pigeons and parrots cause lung disease. However, in 1991, researchers at the University of Cambridge in Britain discovered that a short time after acquiring a cat or a dog, some people suffer less from health problems such as headache, backache and flu. It was also announced recently that Australians who keep pets tend to have less cholesterol in their blood than non-pet owners with comparable lifestyles, making them less likely to develop heart disease.
For the time being, the findings are little more than puzzling correlations. Why should owning a pet make you less likely to suffer from backache Why should it reduce your cholesterol level Many researchers suspect that answers will be found in the subtle links between mental and physical well-being.

Some pessimistic experts fleel that the automobile is bound to fall into disuse. They see a day in the not too-distant future when all autos will be abandoned and allowed to rust.

Many people are afraid to assert themselves (坚持已见). Dr. Robert Alberti, author of Stand Up, Speak Out, and Talk Back, thinks it’s because of their lack of confidence. "Our structure of organization tends to make people distrust themselves," says Alberti. "There’s always a ’superior’ around—a parent, a teacher, a boss—who knows better’. These ’superiors’ often gain when they keep breaking at your self-image."
But Alberti and other scientists are doing something to help people assert themselves. They offer "assertiveness training" courses—AT for short. In the AT course people learn that they have a right to be themselves. They learn to speak out and feel good about doing so. They learn to be aggressive without hurting people.
In one way, learning to speak out is to overc
A. Protect Yourself
B. Try to Speak Out
