Question

【題目】A

The world is not hungry, but it is thirsty. It seems strange that nearly 3/4 of the earth is covered with water while we say we are short of(短缺) water. Why? Because about 97% of water on the earth is sea water which we can’t drink or use for watering plants directly. Man can only drink and use the 3% — the water that comes from rivers and lakes. And we can’t even use all of that, because some of it has been polluted.

Now more water is needed. The problem is: Can we avoid a serious water shortage (短缺) later on?

First we should all learn how to save water. Secondly, we should find out the ways to reuse it. Scientists have always been making studies in the field. Today, in most large cities water is used only once and then runs to the sea or rivers. But it can be used again. Even if every large city reused its water, still there would not be enough. What could people turn to next?

The sea seems to have the best answer. There is a lot of water in the sea. All that needs to be done is to get the salt out of the sea water. This is expensive, but it’s already used in many parts of the world. Scientists are trying to find a cheaper way of doing it. So you see, if we can find a way out, we’ll be in no danger of drying up.

【4】D

【5】C

【解析】

【文章大意】本文介紹了我們地球上非常缺水。為了避免這個(gè)問題，我們應(yīng)該學(xué)會(huì)節(jié)約用水，循環(huán)利用現(xiàn)有的水資源。最重要的是要想辦法提取海水里的鹽，從而獲得更多的淡水資源。

【1】細(xì)節(jié)理解題。根據(jù)第一段的Because about 97% of water on the earth is sea water which we can’t drink or use for watering plants directly.可知因?yàn)榈厍蛏?7%的水是海水，不能直接飲用或用于澆灌植物，所以地球上缺水，故選D。

【2】詞義猜測題。根據(jù)第三段的But it can be used again.可知城市里的水可以被再利用，故選A。

【3】細(xì)節(jié)理解題。根據(jù)第三段的Today, in most large cities water is used only once and then runs to the sea or rivers. But it can be used again.可知城市里的水只被使用一次，故選C。

【4】細(xì)節(jié)理解題。根據(jù)最后一段的 All that needs to be done is to get the salt out of the sea water.可知要避免嚴(yán)重缺水，最重要的是把鹽從海水里提取出來，故選D。

【5】標(biāo)題歸納題。根據(jù)第二段的Now more water is needed. The problem is: Can we avoid a serious water shortage (短缺) later on?可知本文主要介紹全球嚴(yán)重缺水的情況及解決辦法。故選C。
