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 Interact 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.

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 technique　　 B. sharpening tool

C. effective rule　　 D. dividing line

3.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

4.Which of the followiny is the best title of this passage?

A. The Advantages of Online Exams

B. The High-tech Methods in Online Courses

C. The Fight against Cheating in Online Education

D. The War against the Booming of Online Education

Ned and Miles are students at different colleges. Ned applies for an online school, while Miles attends classes on a school campus. The two students each believe that their school system is better than the other.

Ned: Hey, Miles. Are you free to see a movie tomorrow night?

Miles: Sorry, no. I’ll have a class tomorrow and a lot of homework to finish up.

Ned: Oh, that’s too bad. I’m so glad I take classes online. I can decide when, where and how to complete my lessons. It saves a lot of time.

Miles: It sounds good, but I actually really enjoy going to class because it’s a great way to get to know other people. It also helps me learn how to work well with others. If I don’t understand something, I’m always able to ask about it in person. That saves me a lot of time and prevents misunderstanding.

Ned: In an online class, I have to think thoroughly (彻底地) before asking questions. That teaches me how to solve problems on my own.

Miles: Do you ever run into technical (技术上的) problems in your online classes? If you can’t open a file, how can you continue your learning?

Ned: It’s not a big problem. I can email the teacher or contact another student for help.

Miles: But answering questions through emails takes too much time. You may fall behind on your studies.

Ned: You can fall behind, too. What if you get sick or your class gets canceled because the weather is bad? Those aren’t problems for online classes.

Miles: Yes, but there’s usually a make-up (弥补) class if a class is canceled.

Ned: In an online class, I don’t have to worry about missing classes for any reason. I can always review the previous (之前的) lessons online.

Miles: Don’t you feel lonely sometimes? I would feel lonely if I had to learn on my own.

Ned: I’m confident in learning by myself. Besides, an online class gives me more free time to take part in other activities.

Miles: I still prefer having classmates to brainstorm and discuss ideas with. I believe that improves my learning all the time.

Ned: I’m pretty self-disciplined (自律的), and I work better on my own. I can’t focus when working with others.

Miles: I guess everybody learn differently.

1.Ned prefers attending classes on a school campus to studying online, doesn’t he?

________________________

2.Why can't Miles go to see the movie with Ned?

________________________

3.What can Ned do if there’s a technical problem?
