题型：填空题 阅读理解。 Last August, Joe and Mary Mahoney began looking at colleges for their 17-year-old daughter, Maureen. With a checklist of criteria in hand, the Dallas family looked around the country visiting half a dozen schools. They sought a university that offered the teenager's intended major, one located near a large city, and a campus where their daughter would be safe. "The safety issue 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, and the same question was always asked: what about crime? But when college officials always gave the same answer, "That's not a problem here," --Mahoney began to feel uneasy. "No crime whatsoever?" comments 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 by law, but some hold back for fear of bad publicity, leaving the honest ones looking dangerous. "The truth may not always be serious," warms S. Daniel Carter of Security on Campus, InC．, the nation's leading campus safety watchdog 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.1．The Mahoneys visited quite a few colleges last August ________.A．to express the opinions of many parentsB．to choose a right one for their daughterC．to check the cost of college educationD．to find a right one near a large city2．It is often difficult to get correct information on campus crime because some colleges ______.A．receive too many visitorsB．mirror the rest of the nationC．hide the truth of campus crimeD．have too many watchdog groups3．The underlined word "buy" in the third paragraph means __________.A．mind B．admit C．believe D．expect4．We learn from the text that "the honest ones" in the fourth paragraph most probably refers to colleges _________.A．that are protected by campus securityB．that report campus crimes by lawC．that are free from campus crimeD．that enjoy very good publicity5．What is the text mainly about?A．Exact campus crime statisticsB．Crimes on or around campusesC．Effective solutions to campus crimeD．Concerns about kids' campus safety 查看答案
