12．The state of Florida is best known for its beaches and plam trees．But a good mass of it is swampland．The famous Everglades，a slow-moving sheet of water full of plants and alligators（短吻鳄），cover much of the southern part of the state．To the north，the Okefenokee，which is partly in Florida and mostly in neighboring Georgia，is a true swamp（沼泽） with its own alligatoers and snakes and even beautiful orchids．
It was formed when waters from an ancient ocean  receded and a large sandbar blocked most of the water flow to the sea．Left behind was an 1，800-square-kilometer swamp．
There's no big city within 200km，but tourists from all over the world manage to find it．They all want to know about its unusual name．Okefenokee is a Miccosukee Indian word meaning land of trtembling earth．Way back in the swamp are small，floating islands，called hammocks，which one can walk across．But they tremble．Standing on them is like trying to balance on a floating mattress（床垫）．

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 encouraging 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.

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.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. The Advantages of Online Exams

B. The High-tech Methods in Online Courses

D. The War against the Booming of Online Education
