Question

Trees are useful to man in three very important ways.

The first important way is that they provide man with food, wood and other products. Trees provide man and animals with food to live on the earth. It’s not easy for man to live on the earth without trees.

The second important way is that trees give us shade. On a hot summer day, people are eager to (急于) have a rest under the shade of a tree after they have walked a long way. You can imagine how important the shade of a tree is to man and animals.

The third important way is that trees help to prevent droughts and floods. However, in many parts of the world, man has not realized the third important way. He has cut trees down in large numbers. In the end, he finds that he has lost the best friends he had.

【解析】

试题分析：这篇短文从三个方面告诉我们树对人类来说是重要的。一是树可以为人类和动物提供食物、木材和其他产品；二是树可以给人类提供树荫；三是树木可以防止干旱和洪水。因此我们要多植树，注意保护树木。

1.根据短文第二段中Trees provide man and animals with food to live on the earth.可知，树可以给人类和动物提供食物。both…and …和…两者都。

2.根据短文第一段中Trees are useful to man in three very important ways可知，树在三个重要的方面对人类是有用的。即树对人类来说是重要的，是有用的。故填useful和important。

3.根据短文第三段中On a hot summer day, people are eager to (急于) have a rest under the shade of a tree可知，在炎热的夏天，他们可以在树荫下休息。hot 形容词，热的；shade 是一个名词，意思是树荫。

4.根据短文最后一段The third important way is that trees help to prevent droughts and floods可知，树可以帮助防止干旱和洪水。故这里应该填droughts和floods，两个都是名词。

5.根据短文最后一段However, in many parts of the world, man has not realized the third important way. He has cut trees down in large numbers.可知，人类没有意识到树的第三个作用，还在大量地砍伐树木。cut down 砍倒，砍伐。这个句子中使用的句型是stop sb. from doing sth.，阻止某人做某事这个句型，故这里应该填动名词的形式。
