[单项选择]Several recent studies have gained wide attention for reconfirming the tragic disconnection of millions of black youths from the American mainstream. Harry Holzer, an economist at Georgetown University and a co-author of one of the recent studies, feels joblessness is due to largely weak schooling, a lack of reading and math skills at a time when such skills are increasingly required even for blue-collar jobs. Unable to find jobs, he claims, black males turn to illegal activities, especially the drug trade and chronic drug use, and often end up in prison.
As usual, it fails to answer the important questions. Why are young black men doing so poorly in school that they lack basic literacy and math skills Scholars must have known that countless studies by educational experts have found that poor schools, per se(本质上), do not explain why after 10 years of education a young man remains illiterate.
Nor have studies explained why, if .someone cannot get a job, he turns to crime
A. joblessness does not result in crime there
B. joblessness does not necessarily lead to crime
C. there is a large population in those areas
D. Latin America and India are crime-free

Passage Three
Visiting a National Park can be relaxing, inspiring and rejuvenating, but it can also be disturbing. As you drive into Rocky Mountain National Park, and you will see starving elk, damaged meadows and dying forests.

We believed that we were saving these remnants of wild America, but actually we have "protected" them to death.

We must act soon: our parks are dying of old age because we have altered the forces in nature that keep them young and strong.
By tracing the his
A. is in support of the present policies.
B. appreciates the present management techniques.
C. thinks that the forces in nature should be altered.
D. is strongly in favor of the natural processes.
