题目内容
While Jennifer was at home taking an online exam for her business law class, a monitor（监控器）a few hundred miles away was watching her every move.
Using a web camera equipped in Jennifer’s Los Angeles apartment, the monitor in Phoenix tracked how frequently her eyes moved from the computer screen and listened for the secret sounds of a possible helper in the room. Her Internet access was locked - remotely - to prevent Internet searches , and her typing style was analyzed to make sure she was who she said she was: Did she enter her student number at the same speed as she had in the past? Or was she slowing down?
In the battle against cheating, this is the cutting edge and a key to encourage honesty in the booming field of online education. The technology gives trust to the entire system, to the institution and to online education in general. Only with solid measures against cheating, experts say, can Internet universities show that their exams and diplomas are valid - that students haven’t just searched the Internet to get the right answers.
Although online classes have existed for more than a decade, the concern over cheating has become sharper in the last year with the growth of "open online courses." Private colleges, public universities and corporations are jumping into the online education field, spending millions of dollars to attract potential students, while also taking steps to help guarantee honesty at a distance.
Aside from the web cameras, a number of other high-tech methods are becoming increasingly popular. Among them are programs that check students’ identities using personal information, such as the telephone number they once used.
Other programs can produce unique exam by drawing on a large list of questions and can recognize possible cheaters by analyzing whether difficult test question are answered at the same speed as easy ones. As in many university classes, term papers are scanned against some large Internet data banks for cheating.

解析【小题1】细节理解题根据第二段倒数第二句"and her typing style was analyzed to make sure she was who she said she was: Did she enter her student number at the same speed as she had in the past? "可从本句得知监控Jennifer的原因是为了确保她不作弊。故选D，就是不诚实的行为。属于上下义重现。
【小题2】猜词题根据a key to encourage 以及下一句的 the technology 可以知道答案。cutting edge与key是并列关系，同时二者都可以做到鼓励诚实行为。前面this所指代的为上文中提到的防作弊科学技术，由此得知cutting edge应该为advanced technique。
【小题3】细节理解题根据第三段 Only with solid measures against cheating, experts say, can Internet universities show that their exams and diplomas are valid -that students haven't just searched the Internet to get the right answers.可以得出答案。属于原词重现。本解析为学科网名师解析团队原创，授权学科网独家使用，如有盗用，依法追责！
【小题4】细节理解题根据最后一段的第一句" Other programs can produce unique exams by drawing on a large list of questions and can recognize possible cheaters by analyzing whether difficult test questions are answered at the same speed as easy ones. "可知正确选项为A。此题易错选BD。
其实选项A包含了BD选项内容。通过生成大量的有难也有易的问题，然后通过比较答题速度。属于原词重现。
【小题5】主旨大意标题题文章主题句位于第三段第一句"In the battle against cheating, this is the cutting edge and a key to encourage honesty in the booming field of online education."可得知本文主要讨论网络课程的防作弊问题，故选C。此外，文章多次出现cheating，属于原词重现。
