过去，现在和将来(past,now and future)

　　long long ago, many families had three or four children. they couldn't look after everyone well, so the children must do everything by themselves. they were too poor to go to school. some of them liked learning, but they had to go to find jobs to make money. since they were children, they could do lots of difficult things like their parents. sometimes they even did better than them!

　　but now, many families have only one child and they regard their child as a pearl. they did everything for the children. every day, when the child gets up, their parents help him to make the room clean. they also get breakfast ready for their child. when the child is free, they can sleep or do other things, but they needn't do any housework. so many children can't cook; wash their clothes, some don't even know how to clean the floor. that's too bad.in the future, many families will have computers. we can work on the computer instead of going out to do everything. the children also can learn on the computers, so they don't need to move! after a long time, we'll become fatter and fatter. we won't be able to do anything by ourselves!

　　so, which way is good for us? we must think more.
