Question

                                                (B) 

       Why do plants grow in some places and not in others? Why does some land have so many plants growing on it,while other land has almost no plants growing on it at all?

       To grow,plants need some 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 (沙漠) almost don't have trees or grass.

       Plants must also have a place in which to put down their roots (根) and grow. They find it difficult to grow on hard land. The town is on hard land. The plants here can only grow in the soil (土壤) between the cracks of the stones.

       Another thing plants must have before they can grow is food.

       What will happen if we try to make things grow on the sandy (有沙的) beach? A few plants,such as beach grass,will grow in sand,but most plants won’t. Even if (即使) 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.
