问题     The world is not only hungry; it is also thirsty for water. This may seem strange to you because nearly 75% of the earth’s surface is covered with water. But about 97% of this huge amount is seawater or salt water. Man can only drink and use the other 3%—the freshwater that comes from rivers, lakes, underground, and other sources. And we cannot use all of that, because some of it is in the form of iceberg and glaciers (冰河). Even worse, some of it has been polluted.
    However, as things stand today, this small amount of fresh water, which is constantly being replaced by rainfall, is still enough for us. But our need for water is increasing rapidly almost day by day. Only if we take steps to deal with this problem now can we avoid a severe worldwide water shortage later on. A limited water supply would have a bad effect on agriculture and industry.
    We all have to learn how to stop wasting our precious water. One of the first steps we should take is to develop ways of reusing it. Experiments have already been done in this field, but only a small scale. The systems that have been worked out resemble those used in spacecraft.  [br] According to the passage, one of the first steps we should take to stop wasting our fresh water is ______.
选项 A、to deal with this problem now
B、to have lectures on the subject
C、to find ways of recycling it
D、to make more people realize the problem
答案 C
解析 事实细节题。根据题干中的线索词one of the first steps we should take直接定位到文章第三段第二句。由原文看出，节约淡水资源的首要步骤之一是循环利用。C中的 recycle是对原文reuse的同义转述，由此得出C为正确答案。
