问题          Make Use of a Social Intercourse Website to Support a Social Public Order
    As high school students flock to social networking sites, campus police are scanning, their Facehook and MySpace pages for tips to help break up fights, monitor gangs and prevent crime.
Some students object to police looking over their shoulders. But officers responsible for school safety say routine checks of the online forums often add to the knowledge they gather from hallways or schoolyards.
    In recent years, school administrators have blamed some campus fights on Internet conflicts and urged parents to keep watch on their children’s computer activity. But students who use the Web to let their 500 closest friends know what they are doing at all times are sometimes surprised that police are watching, too.
    Police don’t have special privileges on Facebook or MySpace. Students who want to go unobserved can change privacy settings so that their profiles are displayed only to a list of approved people. But the default settings leave those profiles open to many Interact users (in the case of Facebook) or all of them (in the case of MySpace).
    Employers and college admissions counselors have examined online profiles of student applicants for some time. Police across the country have been doing the same for the past two or three years, said Kevin Quinn. a spokesman for the Minnesotabased National Association of School Resource Officers. "If you’re already familiar with the technology, it doesn’t take you but a couple of minutes to hook into the student population and keep an eye on things," Quinn said.
    An entrance into MySpace profiles found high school students discussing drugs, sex and fights. It was all publicly available (although in language that caused reporter to blush).
    Late last month, Fairfax County police announced the arrests of seven Chantilly area teenagers for trying to recruit Franklin Middle School students to a gang. That investigation was aided when a student showed the school resource officer gang symbols littering one of the suspect’s MySpace profiles.
    Fairfax police say they pride themselves on addressing issues in schools before they develop into major problems. "Keeping an eye on Facebook and MySpace has become an extra tool in that effort," they said.
What’s the main idea of this passage?
选项 A、Police are making use of the Internet to maintain good public order.
B、Students should learn to protect their privacy online.
C、Social networking websites have bad influence on high school students.
D、Parents should take control of what their children are doing online.
答案A
解析 主旨大意题。通读全文后就会发现，虽然本文提到过家长、雇主和大学对于网络的监控，但主要内容还是在讲警察通过对高中生常用的网站的监视，得到有用的信息，从而能够预防和制止犯罪的发生，因此[A]“警察在利用网络维护社会治安”与原文大意最为一致。虽然本文在第四段提到学生如果不想让警察知道自己的谈话内容和发布的信息，应该改变自己的隐私设置，但这也正说明了警察并没有利用职务之便侵犯学生的隐私，所以[B]“学生应该学会保护自己的隐私”不是本文主要内容；社交网站本身仅是提供一个场所，本身并没有发布什么观点态度类的信息，也没有提供对学生行为有负面影响的内容，所以[C]“社交网站对学生有不好的影响”被排除；[D]“家长应该对孩子上网进行监控”这个内容仅在第三段中提到过一次，所以不是整篇文章的主题。
