职称英语理工类AB级补全短文例题解析(4)

As long as we have been on earth, we have used the sea around us. We take from the ocean, and we give to it.

We take fishes from the ocean – millions of kilograms of fish, every year, to feed millions of people. __1__. We take minerals from the ocean. One way to get salt is to place seawater in a shallow basin and leave it until it evaporates. __2__. Much gold and silver drift dissolved in the waters of the sea, too. But the sea does not give them up by simple evaporation. Other gifts from the sea are pearls, sponges and seaweed. Pearls become jewelry. __3__. Seaweed becomes food of many kinds – even candy, and ice cream – as well as medicine. Believe it or not, fresh water is anther gift from the sea. We cannot drink ocean water. __4__. But ocean water becomes fresh water when the salts are removed. In the future, we will find ourselves depending more and more on fresh water from the sea.

The sea gives us food, fertilizer, minerals, water, and other gifts. What do we give the sea? Garbage. __5__. Huge as it is, the ocean cannot hold all the water we pour into it, we may need the sea and its gifts more than ever.

We are finally learning that if we destroy our seas, we might also destroy ourselves. Hopefully, it is not too late.

G.Natural sponges become cleaning aids.
H.We pollute the ocean when we use it as a garbage dump.
I.The area of the sea is becoming smaller and smaller.
J.Along with salt, other minerals are left after evaporation.
K.We even use their bones for fertilizer.
L.Some of its contents may cause illness.

答案与解析：

1. E. 空格1前后句都是用“We + 谓语”的结构， 因此B和E可能是答案（句子结构形成排比结构）。B出现在空格中与空格前后句句意不衔接， 而E也是在谈及对海洋的利用， 与空格前后句句意自然衔接， 因此E是答案。

2．D． 选项D中有三处词语分别与空格前句中的词语呼应（salt – salt, minerals – minerals, evaporation – evaporate）, 而D中的mineral与空格后句中的gold, silver构成主题相关词，因此D是答案。

3．A 选项A的句子结构与前后句中的句子结构形成排比结构， 而且也在讲述海里的物品（海绵）的用途， 因此A是答案。

4．F． 虽然B中有两个词语分别于空格4前句中的词语呼应（we – we, ocean – ocean ）, 但是B出现在空格中时与空格前后句之间的衔接不自然， 因此B不是答案。 F与空格前句之间是“观点与解释”的关系。

5．B 选项B中有两处词语分别与空格前句中的词语呼应（we – we, garbage – garbage dump）， 因此B很可能是答案。
