题目内容
There are some factories ________waste water into the stream.
A. pour B. pouring C. poured
B
【解析】
试题分析：句意为：有一些工厂把废水倒进河里。根据语境可知，本句的逻辑主语是factories，但是在这个there be 句型中，谓语动词已经有了are，所以pour就不能再作本句的谓语动词，而应用ing形式，表示具体的一件事。故选B。
考点：考查非谓语动词的用法。

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(产品). 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 can 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（干旱）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.
