Why do plants grow in some places and not in others? Why does some land have so much growing on it, while other land has almost no plants growing on it at all?
To grow, plants need several things. One is warmth. In very cold places almost nothing grows. Plants also need water. In very dry parts of the Earth only a few unusual plants can grow. That’s why dry deserts everywhere are almost not covered by trees or grass.
Plants must also have a place in which to put down their roots and grow. They find it difficult to grow on hard land. The town is built on hard land. The plants here have only the soil (土壤)found between the cracks of the stones to grow in.
Another thing plants must have before they can grow is food.
What will happen if we try to make things grow on the sandy beach? A few plants, such as beach grass, will grow in sand, but most plants won’t. Even if the weather is warm enough and we water the plants each day. Many of them will die because the sand on this beach has almost no food for plants.
【小题1】According to the passage, plants need _____ things to grow well.

Water is the most important in our lives. Not Many people understand this but it’s quite true. The human body can go without food for a long time. We’ve got many examples for this. Yet two or three days without water can usually make people die. Man can’t live without water.

  Many people don’t understand how much water the human body needs to work well, and many people, especially young people, do not drink enough water, even in very hot weather. About two thirds of our body is water. When we do sports, some of the water will get away from our body. If we don’t drink some water, our body won’t have enough water. And if we don’t have enough water, we’ll feel tired and many of us will get ill. So you know how important water is to us.

 But at present we face water crisis(危机). Water is becoming less and less. So， we should protect water resources(资源) and try our best to save water in our daily life. Here are some tips for saving water:

1. Turn off the tap(水龙头) in lime.

2. Take shorter showers.

3. Don’t let water run while washing your face and reuse the water after we finish washing.

4. Encourage your friends and neighbors to join in the action of saving water.

1.Nobody can live without water.

2.About one third of our body is water

3.If one doesn't have enough water, he’ll feel tired and may get ill.

4.We’d better take longer showers and let water run while washing.

5.It’s our duty to protect water resources and save water.
