Question

【題目】根據(jù)短文內(nèi)容理解，選擇正確答案。 Why do plants grow in some places but 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 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 there are almost no trees or grass in dry deserts.
Plants must also have a place to put down their roots and grow. They find it difficult to grow on hard land. The town is built(被建立) on hard land. The plants there have only the soil 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 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.

【解析】本文講述了植物生長所需要的四種自然條件：溫度，水分，土壤和養(yǎng)分。
（1）細(xì)節(jié)理解。根據(jù)短文描述，可知植物生長需要四種條件，溫度，水分，土壤和養(yǎng)分。所以答案是C。
（2）詞意猜測。聯(lián)系下文of the stones 石頭之間，可知此處指的是縫隙，所以答案是A。
（3）細(xì)節(jié)理解。根據(jù)第二段In very dry parts of the Earth only a few unusual plants can grow.描述，可知植物很難在干旱的地方生長，所以答案是B。
（4）細(xì)節(jié)推理。這篇短文主要介紹了植物生長所需要的條件，故最可能出自一本科學(xué)類書籍，所以答案是A。
