Which day is the most important for you? Your birthday, the first day of your work or the day you win a prize. Many teenagers may think their birthday is the happiest time because they can receive many wonderful presents and have much fun with their friends. Others may regard the starting day of their work as the most meaningful. They think it's the first big step in their life and they can depend on themselves. They like to deal with challenges rather than to ask for the help of adults.
According to a survey, more than half of the Chinese people, certain ages and birthdays are especially important. One hundred days after a baby's birth has special meaning. On that day, relatives(亲戚) and friends come to bless the baby. In northern part of China, like Inner Mongolia, a child's 12th birthday is a big day. This is when a child becomes a teenager. Eighteen is another important age, which means you must be responsible(负责任的) for what you have done in laws. As for adults, maybe the anniversary of their marriage(结婚周年庆) is the most important. For some old people, the 60th or 70th birthday is also very important. They like to be cared about by all his family and friends, and the big family get-together can provide them a good chance to recall(回忆) the past.

What do people do with their old, out-of-date but still useful computers?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.
