    There is an old saying: Early to bed, early to rise, makes a man healthy, wealthy and wise. It means that we should go to bed early and get up early the next morning. By doing this, we will be in good health. And we'll also be rich and clever.

    It's true that our bodies need to have enough sleep to be healthy. Children should have a ten-hour sleep every night. Those who do not have enough sleep can't do their work very well. They will not be clever and they may not get wealthy in the future.

    The body needs exercise as well. Walking, running, jumping, riding bikes and playing games are all exercise. Exercise helps to keep the body strong and fit. It also helps the blood(血液)to move around inside the body. The head needs blood too. So exercise helps people think better.

    Shenzhen is a city in South China. It is not very big, but it has attracted people of the whole country and the whole world as well.

    Just about twenty years ago, it was only a small fishing village. There were not many people there. Most of them lived on fishing. Things have greatly changed since the 1980's. It became the first special economic zone (经济特区) in China.

    Because of the opening policy(政策), economic changes between China and the outside world have increased greatly. People can come and go easily between Shenzhen and Hong Kong. Both foreigners and Chinese have built a lot of factories, companies and tourists' attractions there. People all over the country have come to find jobs. Many of them have settled down in this new booming(兴起的) city.

    Shenzhen is developing so fast that it has become a well-known metropolis(大都市) in China.
