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. (46) 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 (蒸发). (47) Much gold and silver drift
dissolved (溶解) 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. (48) 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. (49)
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. (50) 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. A. Natural sponges become cleaning aids.
B. We pollute the ocean when we use it as a garbage dump.
C. The area of the sea is becoming smaller and smaller.
D. Along with salt, other minerals are left after evaporation.
E. We even use their bones for fertilizer. F. Some of its
contents may cause illness.
