Early to bed and early to rise makes a man healthy, wealthy and wise.

This is an old English saying (谚语). It means that we should go to bed early at night and get up early in the morning. If we do, we shall be healthy. We shall also be rich and clever.

Is this true? Perhaps it is. The body must have enough sleep. Children of your age need ten hours’ sleep every night. If you go to bed late, you can’t have enough sleep. Then you can’t think carefully and your homework will be wrong. You will not be wise and you may not become wealthy!

Some people go to bed late at night and get up late in the morning. This is not good for them. We should sleep at night when it is dark. The dark helps us sleep well. When the daylight comes, we should get up. This is the time for exercise. If the body is not used, it will become weak. Exercise keeps it strong.

Exercise helps the blood (血液) to move around inside the body. Blood takes nutrition (营养) to all parts of our bodies. The brains (大脑) in our heads also need blood. We think with our brains. If we keep our bodies healthy, and take exercise, we can think better!

Our bodies also need air to breathe (呼吸). Without air we will die. Get up early in the morning and we can have plenty of clean, fresh air. That will keep us healthy and happy.

It began with a red paper clip and ended with a house. Kyle MacDonald, a 26-year-old Canadian, got a three-bedroom house through 14 trades (交换) that started with a single red paper clip.[来源:学。科。网Z。X。X。K]
Encouraged by Kyle’s successful experience, now more and more young people around the world are starting their own trading activities. They set up websites where people can trade things they don’t usually use with other people. A website called Peerflix allows people to trade their used DVDs. These traders usually prefer face-to-face trading, which means they don’t have to worry about who is going to pay for the delivery (递送).
Last year, a young girl in Beijing decided to follow the example of Kyle. She started with a paper clip and hoped to get a house in the end. After several trades she now has a piano which is more than 10,000 yuan. But she may still have a long way to go.
You may be puzzled about why people are doing this. In fact, everyone in the trade activities gets things that are useful to them. Just as Kyle said, “What’s more important to a man dying of thirst in the desert — one million dollars or a glass of water?” Kyle’s words probably show why these trades are poplar among young people.
