Good health is very important. Everyone should do all he can to stay healthy. Being in good health means having both body and mind in good order, free from illness and pain.
Good food, plenty of water, cleanness and plenty of rest all help in keeping our machines running as they should. Food does many things for our bodies. It gives what we need for keeping good health. It gives us energy for work and play. No food gives everything we need. We should eat foods of different kinds. Having enough to eat is not the same as having the right food.
The water we drink helps wash away wastes formed inside our bodies. It also puts back the water we lose when we perspire(流汗). Our bodies are actually more than half water. We must drink enough to replace what we lose.
We feel better and look better when we are clean. A bath every one or two days is a good rule for most of us. Brushing our teeth is important part of keeping clean.
Sleep is the best kind of rest. Growing children need more sleep than grown-ups. Children's bodies not only have to be repaired; they also have to grow, No one's body can grow bigger properly while he is working and playing and wearing it out (疲劳).
It has been useful to work for good health. Millions of years ago, people live only 20 years. Now people can live about 70 years. It has gone up 20 years just since the beginning of the present century.

(答案→)B 解析：本文讲述了要想身体健康，人们需要吃各种各样的事物，因为各种各样的时候能够提供身体所需的不同的东西。而身体流汗排除水分，所以就需要补充大量的水。洗澡睡眠对我们的身体相当重要。小孩子应该尤其主意调节工作玩耍与睡眠的关系。 【小题1】细节理解题。句意；你为什么应该吃不同种类的事物？根据句子：No food gives everything we need. We should eat foods of different kinds.没有哪种事物能够提供我们需要的一切事物，我们应该吃不同种类的事物。故选B。 【小题2】词义猜测题。句意：我们应该喝足够的水来代替我们失去的部分。代替的含义是什么？根据文章中：It also puts back the water we lose when we perspire(流汗).
