[单项选择]We sometimes think humans are uniquely vulnerable to anxiety, but stress seems to affect the immune defenses of lower animals too. In one experiment, for example, behavioral immunologist (免疫学家) Mark Laudenslager, at the University of Denver, gave mild electric shocks to 24 rats. Half the animals could switch off the current by turning a wheel in their enclosure, while the other half could not. The rats in the two groups were paired so that each time one rat turned the wheel it protected both itself and its helpless Partner from the shock. Laudenslager found that the immune response was depressed below normal in the helpless rats but not in those that could turn off the electricity. What he has demonstrated, he believes, is that lack of control over an event, not the experience itself, is what wakens the immune system.
Other researchers agree, Jay Weiss, a psychologist at Duke University School of Medicine, has shown that animals who are allowed to control unpleasant stimuli don’t

[单项选择]New research from Australia supports the belief that many pet owners have—it shows that pets are good for your health. The findings of this new study suggest that people who have pets are at less risk from heart disease than those who do not.

They took tests that measured a variety of different factors known to be involved in heart disease—blood pressure, and blood levels of cholesterol (胆固醇) and triglyceride (甘油三酯). Also, people were asked about their lifestyles.
The 800 people who owned pets had lower levels on each of the factors measured than those who did not own pets. The differences wer
