11.While Jennifer was at home taking an online exam for her business law class,a monitor (監(jiān)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.

分析 本文為說明文.網(wǎng)絡(luò)教育越來越受歡迎,但是在考試時如何防止考生作弊呢?網(wǎng)絡(luò)教育文憑的可信度與考試防作弊程序的有效性密切相關(guān).核實考生個人信息的程序以及監(jiān)控分析考生答題速度的程序都可以遏制網(wǎng)絡(luò)考試中出現(xiàn)的作弊現(xiàn)象.
解答 41.答案:D.推理判斷題.根據(jù)第二段倒數(shù)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?"可從本句得知監(jiān)控Jennifer的原因是為了確保她不作弊.故選D,就是不誠實的行為.
42.答案:A.猜測詞義題.根據(jù)"a key to encourage"以及下一句的"the technology"可以知道答案.cutting edge與key是并列關(guān)系,同時二者都可以做到鼓勵誠實行為.前面this所指代的為上文中提到的防作弊科學(xué)技術(shù),由此得知cutting edge應(yīng)該為advanced technique.
43.答案:B.細(xì)節(jié)理解題.根據(jù)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."可知只有通過強有力的手段來杜絕作弊,網(wǎng)絡(luò)大學(xué)的考試和文憑才有效,B項與之意思一致.
44.答案:A.細(xì)節(jié)理解題.根據(jù)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."可知正確選項為A.此題易錯選BD.其實選項A包含了BD選項內(nèi)容.通過生成大量的有難也有易的問題,然后通過比較答題速度來辨別可能的作弊者.
45.答案:C.主旨大意題.文章主題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."可得知本文主要討論網(wǎng)絡(luò)課程的防作弊問題,故選C.此外,文章多次出現(xiàn)cheating,屬于原詞重現(xiàn).
