What do people do with their old, out-of-date but still useful computers? Most people don’t know what to do with them. Many old computers are put away in homes. Many more are simply thrown out with the rubbish.  
Some companies are thinking of ways to bring down the number of old computers. Sony has agreed to help recycle old Sony products. Dell, Hewlett-Packard and other companies now also take back some old computers.  
In some countries, laws are being passed, too. Computer companies will have to collect and recycle their used products. And 70% of computer waste must be recycled. The idea behind the laws is that computer companies themselves should pay the cost. That will encourage them to make computers that are easier and cheaper to repair and upgrade(升级).  
Yet while many people are throwing away good computers, others cannot afford them at all. Hundreds of organizations are working to solve this problem. They collect and repair old computers. Some also teach others how to repair computers.  
The computers then go to schools, charities and people who need them. Giving a used computer to one of these organizations can turn one person’s rubbish into someone else’s useful things—and cut down on waste, too.

It's the end of class. When the bell rings, students of Luohu Foreign Languages School in Shenzhen quickly take out their cell phones. They want to log on* to their micro blogs to check the interesting things that have happened in the last hour.

  Since last year, the trend* of micro blogging has swept the country. Recent surveys shows that most students in middle schools have a micro blog and some even update* their blogs over five times per day.

  "We learn many fresh and interesting things on micro blogs and they have become popular topics in class," said Andy Liang, 14. "If you do not know about them, you are out of the loop."

  It is also a great place for students to let out stress. "My parents always ask me to study all the time, and encourage me before exams, but it really adds pressure," said Simon Zhang, 15. "When I share these feelings on my micro blog, I get many replies from friends in the same situation, which makes me feel better."

  But parents are worried that micro blogging could be a waste of time. Some misleading messages may even cause danger to kids, they said.

  Mr. Shen, a professor at the China Education Association, suggests parents not worry too much as long as kids are not crazy about micro blogging. Maybe it can become a window for parents to understand their children. "If parents can read their children's micro blogs, they'll know their thoughts, thus leading to better communication and solutions to problems," he said. He also gives some tips for kids.

  ---Don't micro blog for more than one hour a day.

  ---Never micro blog in class.

  ---Try to talk face to face with people from time to time.

  ---Be critical*. Don't trust all the messages on a micro blog.

1.The underlined part "out of the loop" in the passage probably means                 .

  A. not popular    B. not excited    C. unhealthy        D. unlucky

2.Micro blog made Simon       when he shared his feelings and got replies on his micro biog.

  A. feel sad       B. let out stress   C. add pressure      D. make friends

3.We can know from Mr. Shen that micro blogging can                  .

  A. make kids crazy while logging on to it        

 B. bring a lot of misleading messages

  C. become a window to understand young kids      

D.lead to worse communication

4.Which statement is TRUE according to the passage?

  A. It's good for kids to micro blog for more than one hour a day.

  B.Kids should trust all the messages on a micro blog because they are useful.

  C.The trend of micro blogging has swept the country since five years ago.

  D. Kids should try to talk face to face with people, not just micro blogging.
