While Jennifer was at hose 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 camers, 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.

One day, when I was working as a psychologist in England，an adolescent boy showed up in my office. It was David. He kept walking up and down restlessly, his face pale, and his hands shaking slightly. His head teacher had referred him to me.  "This boy has lost his family," he wrote.  "He is understandably very sad and refuses to talk to others, and I'm very worried about him. Can you help?”

       I looked at David and showed him to a chair. How could I help him? There are problems psychology doesn’t have the answer to, and which no words can describe. Sometimes the best thing one can do is to listen openly and sympathetically

       The first two times we met, David didn't say a word. He sat there, only looking up to look at the children's drawings on the wall behind me. I suggested we play a game of chess. He nodded. After that he played chess with me every Wednesday afternoon一in complete silence and without looking at me. It's not easy to cheat in chess, but I admit I made sure David won once or twice.

Usually, he arrived earlier than agreed. took the chess board and pieces from the shelf and began setting them up before I even got a chance to sit down. It seemed as if he enjoyed my company. But why did he never look at me?

       "Perhaps he simply needs someone to share his pain with," I thought. "Perhaps he senses that I respect his suffering.” Some months later, when we were playing chess, he looked up at me suddenly.

       "It’s your turn," he said.

       After that day, David started talking. He got friends in school and joined a bicycle club. He wrote to me a few times about his biking with some friends, and about his plan to get into university. Now he had really started to live his own life.

       Maybe I gave David something. But I also learned that one一without any words一can reach out to another person. All it takes is a hug, a shoulder to cry on, a friendly touch, and an ear that listens.
