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.

1.Why was Jennifer watched in an online exam?

A．To correct her typing mistakes.

B．To find her secrets in the room.

C．To prevent her from slowing down.

D．To keep her from dishonest behaviors.

2. The underlined expression cutting edge in Paragraph 3 is closest in meaning to______.

A．advanced techniqueB．sharpening tool

C．effective rule D．dividing line

3.For Internet universities, exams and diplomas will be valid if _____.

A．they can attract potential students

B．they can defeat academic cheating

C．they offer students online help

D．they offer many online courses

A new generation addiction is quickly spreading all over the world. Weboholism（網癮）, a twentieth century disease, affects people from different ages. They surf the net, use e-mail and speak in chat rooms. They spend many hours on the computer, and it becomes a compulsive habit. They cannot stop, and it affects their lives.

Ten years ago, no one thought that using computers could become compulsive behavior that could affect the social and physical life of computer users. Such behavior has seriously affected teenagers and college students. They are likely to log(寫日志) on computers and spend long hours at different websites.

They become hooked（著迷） on computers and gradually their social and school life is affected by this situation.
