(2017·河南商洛模拟)
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 numbers they once used.
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.As in many university classes，term papers are scanned against some large Internet data banks for cheating.

语篇解读 本文为说明文。网络教育越来越受欢迎，但是在考试时如何防止考生作弊呢？网络教育文凭的可信度与考试防作弊程序的有效性密切相关。核实考生个人信息的程序以及监控分析考生答题速度的程序都可以遏制网络考试中出现的作弊现象。
26．Why was Jennifer watched in an online exam? A．To correct her typing mistakes. B．To find her secrets in the room. C．To keep her from dishonest behaviors. D．To prevent her from slowing down. 答案 C
解析 推理判断题。根据第二段提到的监控内容以及第三段第一句中的“In the battle against cheating...”可知，对Jennifer进行监控是为了防止她考试作弊。故选项C正确。 27．The underlined expression “cutting edge” in Paragraph 3 is closest in meaning to “”．
A．advanced technique B．sharpening tool C．effective rule D．dividing line 答案 A
解析 词义猜测题。根据上文可知，网络远程监控设备是在蓬勃发展的网络教育领域中鼓励诚实的前沿科技，也是关键所在。由下一句中的“The technology...”也可推测出cutting edge是一种“尖端科技”，故A项正确。
28．Some programs can find out possible cheaters by . A．producing a large number of questions B．checking the question answering speed C．scanning the Internet test questions D．giving difficult test questions 答案 B
解析 细节理解题。除了远程监控手段外，文章在最后两段还介绍了两种防止作弊的方法，
23
一种是核实考生的个人信息，另一种则是分析考生的答题速度，B项与文章最后一段内容一致。 Ⅴ.书面表达
