Question

Why do plants grow in some places and not in other? 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 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.

試題分析：這篇文章主要講了為什么植物生長在一些地方而不是生長在其他地方呢?為什么一些土地生長很多植物,而其他土地上幾乎沒有植物，這篇文章給了原因。

1.細節(jié)理解題。根據(jù)The plants here have only the soil found between the cracks of the stones to grow in. 這里的植物只有在石頭的縫的土壤之間生長。可知選A。

2.細節(jié)理解題。根據(jù)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. 植物也需要水。在地球上非常干燥的部分只有幾個不尋常的植物可以生長。這就是為什么干的沙漠都幾乎未被樹或草覆蓋。可知應(yīng)選B。

3.細節(jié)理解題。根據(jù)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. 一些植物,如海灘草,能種在沙子上,但大多數(shù)植物不會。即使天氣足夠暖和,我們每天澆花,他們中的許多也會死,因為在這個海灘上的沙子幾乎沒有植物的食物。故選D。

4.歸納理解題。通過這篇文章最可能在科學(xué)書中找到。故選A。
