Nowadays,many families have only one child.In the past,the children used to go to school alone.

They did housework by themselves at home.When they grew up,they could work hard and do well.

But now things are different.The children are taken to school by their parents every day.Everything they do depends on their parents.When they grow up,they can't do a complete thing without the help of others.So I think it is important for us to do things by ourselves.
