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)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 whatever?” 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(统计数字) by law, but some hold back for fear of bad publicity（关注）, 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 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.
【小题1】It is often difficult to get correct information on campus crime because some colleges ____.

More Americans are Googling themselves ------ and many are checking out their friends, co-workers and romantic interests, too.
In a report Sunday, the Pew Internet and American Life Project said 47 percent of U.S. adult Internet users have looked for information about themselves through Google or another search engine.
That is more than twice the 22 percent of users who did in 2002, but Pew senior research specialist Mary Madden was surprised the growth wasn't higher.
"Yes it's doubled, but many Internet users have never done this simple act of plugging their name with search engines," she said.
Americans under 50 and those with more education and income were more likely to self-Google because their jobs demand a certain online persona.
Meanwhile, Pew found that 53 percent of adult Internet users admit looking up information about someone else, not including celebrities.
Often, it's to find someone they have lost touch with. But looking up information about friends, relatives, colleagues and neighbors also was common.
Although men and women equally searched for online information about themselves, women were slightly more likely to look up information about someone they are dating.
In many cases, the search is done to find someone's contact information. But a third of those who have conducted searches on others have looked for public records, such as bankruptcies(破产) and divorce （离婚）proceedings. A similar number have searched for someone else's photo.
Few Internet users say they Google themselves regularly —— about three-quarters of self-searchers say they have done so only once or twice. And most who have done so consider what they find accurate.
Pew also found that teens were more likely than adults to restrict who can see their information at an online hangout(常去之处) like Facebook or News Corp's MySpace.
【小题1】The number of American adult Internet users______ Mary Madden.

It seems that all your friends’ names on MSN have added a little green “I’m” symbol overnight. If you ask what is going on, someone will tell you it’s a charity activity.
Though this charity program has not yet officially begun for Chinese users, this little green symbol has proven popular among Chinese Windows Live Messenger users.
Windows Live Messenger’s official blog announced on March 1 that Microsoft was beginning an “I’m” program in the United States. Every time someone starts a conversation using “I’m”, Microsoft shares a part of the program’s advertising income with nine organizations devoted to social causes. With every instant message a user sends, it helps deal with things one feels most interested in, including poverty, child protection, disease and worsening environment.
One only has to add a certain code next to one’s name for the organization one would like to support. “*red’u” is for the American Red Cross, “*bgca” is for Boys & Girls Clubs of America and “*unicef” stands for the American branch of UNICEF.
After a Chinese blogger named “hung” introduced this program on his blog on March 2, “I’m” entered the Internet in China with no actual support from Microsoft.
Beijing-based Youth Weekend reported that famous IT blogger Keso regarded this program’s rapid spread as a successful virus marketing case. He thinks that the success of the “I’m” program is because it’s spread by users without being a bother to others. This answers why “I’m” has spread so rapidly across the Internet like a virus with almost no advertisement.
However, Feng Jinhu from the press center for Microsoft China told Youth Weekend that the “I’m” project is only for Messenger users in the United States. Instant messages sent by Chinese users would not count.
This has not affected Chinese Messenger users’ interest in the little green symbol. These users hope their instant messages will actually contribute to charitable organizations someday.
