What we take from and give to the sea
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.
答案與解析：
1. E. 空格1前后句都是用“We + 謂語”的結(jié)構(gòu)， 因此B和E可能是答案（句子結(jié)構(gòu)形成排比結(jié)構(gòu)）。B出現(xiàn)在空格中與空格前后句句意不銜接， 而E也是在談及對海洋的利用， 與空格前后句句意自然銜接， 因此E是答案。
2．D． 選項D中有三處詞語分別與空格前句中的詞語呼應(yīng)（salt – salt, minerals – minerals, evaporation – evaporate）, 而D中的mineral與空格后句中的gold, silver構(gòu)成主題相關(guān)詞，因此D是答案。
3．A 選項A的句子結(jié)構(gòu)與前后句中的句子結(jié)構(gòu)形成排比結(jié)構(gòu)， 而且也在講述海里的物品（海綿）的用途， 因此A是答案。
4．F． 雖然B中有兩個詞語分別于空格4前句中的詞語呼應(yīng)（we – we, ocean – ocean ）, 但是B出現(xiàn)在空格中時與空格前后句之間的銜接不自然， 因此B不是答案。 F與空格前句之間是“觀點與解釋”的關(guān)系。
5．B 選項B中有兩處詞語分別與空格前句中的詞語呼應(yīng)（we – we, garbage – garbage dump）， 因此B很可能是答案。
