Look at the diagram. It   ?    something of home computer used by a group of young people. We asked thirty young people between fourteen and eighteen. We asked them how much  ?   they usually spent on their computers in a week, but we were most interested in  ????   they used their computers for.

The usual time spent on a computer in a week was about twelve hours, with  ???? user about thirty-two hours, and the lowest user only five hours.

All the children said they usually used computers  ??   . Fourteen children told us they did some word processing (文字处理)  ??    . Only two of them said computers helped with their lessons, and eight people told us they kept addresses and phone numbers on their computers or used   ??   as diaries. Only three people said they were learning to make computer programmes and nobody looked up databases(数据库). None of them used computers for any  ??   use.

The results show that computer use is quite high among 14～18 year old. They also show quite clearly that computers  ??   by most young people as little more than game machines. The only other great uses are for word-processing and  ??  address lists. Though computers are common in the homes of young people, they have not yet become useful in everyday life.

Chinese space trainer Wang Yuan has been chosen as one of the volunteers for the Mars-500 test project. He was very happy to be chosen and will accept the meaningful challenge(挑战) Another five volunteers are all space lovers., including three Russians, an Italy-Colombian and a Frenchman. They are about to feel what it’s like to travel to Mars, only without leaving the earth. They are locked up together for a year and a half under a similar condition to the red planet during the whole process. So the experiment is called Mars-500.
When reporters asked what they would miss most during the 520-day special life, French trainer Charles said:”For me, it will be mainly my family, the sun and fresh air.”
The Mars-500 test will be in a special building in Moscow, Russia. Although the people won’t leave the building, they will fell as if they are on a real trip to the Mars. The most difficult thing will be to be separated(分离) from the people that they used to live with. The trainer won’t see sunsets, sunrises, won’t feel rain for 18 months. That will be hard.
The main task is to study the “Man and environment”. It’ll care about the astronauts’ getting experience and physical effects. The 520-day-test is divided into three parts,the first 250days to Mars, the middle 30days of landing on Mars, the last 240 days to return to the earth. Everyone will stay there alone for a long time and will work lonely. They will have to make decisions themselves and only then report to the earth, and the earth will tell them whether they do the right thing or not.
Each astronaut is preparing for the great challenge. It is learned that they will be launched（发射）early in June. And the experiment will end in November 2011.
【小题1】 _______ members were chosen as volunteers.

“At three or four in the morning and I surf the net.”

“I often check my e-mail forty times a day.”

“I often spend more than three hours during one time on the net.”

“I spend more time in chat rooms than with my ‘real-1ife’ friends.”

Do you know any people like these? They are part of a new addiction（瘾）called Internet addiction. Internet addicts spend at least thirty to forty hours online every week. The use of the Internet can be an addiction like drug(毒品) use. People lose control of the time they spend on the Internet. For example, one college student was missing for several days. His friends were worried, and they called the police. The police found the student in the computer lab: he was surfing the net for several days straight.

Studies show that about 6 to 10% of Internet users become addicted. And people worry about the teens because the Internet is changing the playing field for some of them. They spend more time in cyberspace than in the real world of friends and family.

Is “surfing the net” a hobby or an addiction for you? You may have a problem if you have these symptoms（症状）：

●You do not go to important family activities or you do not do school work because you like to spend hours on the Internet.

●You can’t wait for your next online time.

●You plan to spend a short time online, but then you spend several hours.

●You go out with your friends less and less.
