[填空题]
America is a country that now sits atop the cherished myth
that work provides rewards, that working people can support their families. It’s
a myth that has become so divorced from reality that it might as well begin with
the words "Once upon a time". Today 1.6 million New Yorkers suffer from "food
insecurity", which is a fancy way of saying they don’t have enough to eat. Some
are the people who come in at night and clean the skyscrapers that glitter along
the river. Some pour coffee and take care of the aged parents of the people who
live in those buildings. The American Dream for the well-to-do grows from the
bowed backs of the working poor, who too often have to choose between groceries
and rent.
In a new book called "The Betrayal of Work", Beth
Shulman says that even in the booming 1990s one out of every four American
workers made less than $8. 70 an hour, an income equal to the government’s
poverty level for a family of four. Many, if not

[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
A. they associated it with stomachach
