贯彻“三个代表”重要思想，关键在坚持与时俱进，核心在（），本质在坚持执政为民。 A.

Last August, Joe and Mary Mahoney began looking at colleges for their 17-year-old daughter, Maureen. With a checklist of criteria (衡量标准，尺度) in hand, the Dallas family looked around the country visiting half a dozen schools. They looked for a university that offered the teenager’s intended major (主修科目), one located near a large city, and a campus (大学校园) where their daughter would be safe.

“The safety issue (问题) is a big one,” says Joe Mahoney, who quickly discovered he wasn’t alone in his worries. On campus tours other parents voiced similar concerns (担心), and the same question was always  asked: What about crime? But when college officials al ways gave the same answer---“That’s not a problem here.” ---Mahoney began to feel uneasy.

“No crime whatsoever?” comments (评论) Mahoney today. “I just don’t buy it.” Nor should he: In 1999 the U.S . Department of Education had reports of nearly 400,000 serious crimes on or around our campuses. “Parents need to understand that times have changed since they went to college,” says David Nichols, author of Creating a Safe Campus. “Campus crime mirrors the rest of the nation.”

But getting accurate information isn’t easy. Colleges must report crime statistics (统计数字)  by law, but some hold back for fear of bad publicity (名声), leaving the honest ones looking dangerous. “The truth may not always be serious,” warns S. Daniel Carter of Security on Campus, Inc., the nation’s leading campus safety watchdog (监视) group.

To help concerned parents, Carter promised to visit campuses and talk to experts around the country to find out major crime issues and effective solutions.
