Geraldo Rivera is well known for his compassionate investigative reports on WABC-TV Eyewitness News. He has done exposes (揭露性报道) of New York City's welfare hotels, the over-pricing of prescription drugs, and drug abuse. In 1971, he received the Associated Press Broadcaster of the Year Award for the program Drug Crisis in East Harlem. He received the award again in 1972 for program Migrants, Dirt Cheap.
His most famous expose however was done on the horrible conditions at Staten Island's Willowbrook State School. It is the world's largest institution for the mentally disabled. His investigation began when be and his camera crew gained access to one of the buildings. Geraldo's emotionally charged reports exposed the unsanitary (不卫生的) conditions and neglectful, often abusive, treatment of the patients. He cried over what he discovered, and he made his viewers cry, too. The program created a public plea for reform, and changes were made. Governor Nelson Rockefeller of New York restored ＄20 million to the school's slashed budget. The program Willowbrook earned him the Scripps-Howard Award, an Emmy (埃米金像奖), and the Robert F. Kennedy Journalism Award.
Geraldo Rivera has continued working for the mentally disabled. He founded One-to-One, a charity (慈善机构) that provides small group homes for the care of mentally disabled in the community. He hosts huge outdoor festivals for mentally disabled in New York City's Central Park. He also wrote a book about some of the courageous people he has met as an investigative journalist. It is called A Special Kind of Courage. As he himself says, "I make no pretense (矫饰) of objectivity. But I'm not just in the business of making people cry. I'm in the business of change."

A classic series of experiments to determine the effects of overpopulation on communities of rats was conducted by a psychologist, John Calhoun. In each experiment, an equal number of male and female rats were placed in an enclosure. The rat populations were allowed to increase. Calhoun knew from experience approximately how many rats could live in the enclosures without experiencing stress due to overcrowding. He allowed the population to increase to approximately twice this number. Then he stabilized the population by removing offspring that were not dependent on their mothers. At the end of the experiments, Calhoun was able to conclude that overcrowding causes a breakdown in the normal social relationships among rats, a kind of social disease. The rats in the experiments did not follow the same patterns of behavior. as rats would in a community without overcrowding.
The females in the rat population were the most seriously affected by the high population density. For example, mothers sometimes abandoned their pups, and, without their mothers' care, the pups died. The experiments verified that in overpopulated communities, mother rats do not behave normally. Their behavior. may be considered diseased, pathological (病理学的).
The dominant males in the rat population were the least affected by overpopulation. Each of these strong males claimed an area of the enclosure as his own. Therefore, these individuals did not experience the overcrowding in the same way as the other rats did. However, dominant males did behave pathologically at times. Their antisocial behavior. consisted of attacks on weaker male, female, and immature rats. This deviant (不正常的) behavior. showed that even though the dominant males had enough living space, they too were affected by the general overcrowding.
Non-dominant males in the experimental rat communities also exhibited deviant social behavior. Some withdrew completely, avoiding contact with other rats. Other non-dominant males were hyperactive, chasing other rats and fighting each other.
The behavior. of the rat population has parallels in human behavior. People in densely populated areas exhibit deviant behavior. similar to that of rats in Calhoun's experiments. In large urban areas, such as New York City, London, and Cairo, there are abandoned children. There are cruel, powerful individuals, both men and women. There are also people who withdraw and people who become hyperactive. Is the principal cause of these disorders overpopulation？ Calhoun's experiments suggest that it might be. In any case, social scientists and city planners have been influenced by the results of this series of experiments.
Calhoun stabilized the rat population ______.
A．when it was double the number that could live in the enclosure without stress

D．all of the above are correct
A．the public concern and request for changes
B．the improvement of the conditions there
C．a considerable increase in the school's budget

A．Calhoun's experiment is still considered important today.
B．Overpopulation causes pathological behavior. in rat populations.
C．Stress does not occur in rat communities unless there is overcrowding.
D．Calhoun had experimented with rats before.
A．Dominant males had adequate living space.
B．Dominant males were not seriously affected by overcrowding as the other rats.
