Computers are useful machines. They can help people a lot in their daily life. For example, they can help people to save much time to do much work, and they can help people to work out many problems easily. Our country asks everyone to learn to use computers before the twenty-first century, except the old people.

Today more and more families own computers. Parents buy computers for their children. They hope computers can help them improve their studies in school. Yet, many of their children use computers to play games, to watch videos or to chat. computers can not help children to study but make them fall behind. So computers are locked in boxes by parents.

A volunteer in the future

There are lots of volunteers around us now. They don't do it for money. They do it only for happiness or for others.

If I have a chance to join a Volunteer Club, I will try my best to help others. In my class, I am good at Maths and Science. I can help my classmates who are in trouble if I am free. In the primary school, I can help teach young students paint because I am good at drawing. And I am good at singing, so I can sing songs to cheer up the sick people in hospital. Also, I can help the old people in the old people's home. I can do the housework for them because I think the old people will be very tired if they do the housework by themselves.

Except(除了) these, I can do some other things. Not only I feel good about helping others, but also I do something useful. So I think I should study hard to improve my skills and I will help others more in the future.

1.Why do lots of people want to be volunteers?

___________________________________________________________

2.What does the writer think of helping others?
