Question

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 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】

試題分析:本文主要討論了網(wǎng)絡(luò)課程的防作弊問(wèn)題。在幾百英里以外的遠(yuǎn)程網(wǎng)絡(luò)考試的教室內(nèi)安裝監(jiān)控器，這種監(jiān)控器可以監(jiān)測(cè)考試人的眼睛從電腦屏幕上離開(kāi)的頻率，而且還可以監(jiān)聽(tīng)房間里可能的助考者。

1.細(xì)節(jié)理解題。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? "可知監(jiān)控Jennifer的原因是為了確保她不作弊。故選D。

2.詞義猜測(cè)題。根據(jù)and前面內(nèi)容a key to encourage 以及下一句的 the technology 可知cutting edge與a key to encourage是并列關(guān)系，同時(shí)二者都可以做到鼓勵(lì)誠(chéng)實(shí)行為。再根據(jù)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。

3.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.可以判斷只有杜絕了考試作弊行為，考試和文憑才會(huì)更有效，選B。
