Why does some land have so many plants growing on it, while other land has almost no plants 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. Thats why dry deserts are not covered by trees or grass.来源:gkstk.Com Plants must have a place to put down their roots and grow. They find it difficult to grow on hard land. However, plants have been found 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 beach? A few plants, such as beach grass, will grow in sand, but most plants wont. Even if the weather is warm enough and we water the plants each day, most of them will die because the sand on the beach has almost no food for plants.根据短文内容，选择最佳答案。（10分）6.According to the passage, plants need _ things to grow well.A. twoB. threeC. fourD. five7.
