Can we ever _____ hunger from the world?A. eliminate B. throw C. stop D. prevent
第1题:
B
The world is not only hungry,it is also thirsty for water. this may seem strange to you,since nearly 75% of the earth is covered with water. But about 97% of this water is sea water.Man can only drink and use the other 3% fresh water that comes from rivers,lakes,under-ground and other places. And we cannot even use all of that,because some of this fresh water has been made dirty.
At the moment,this small amount(数量) of fresh water is still enough for us. However,our need for water is getting greater and greater. Only if we take steps to solve this problem now,we can get away from a serious world water shortage later on. The people of the world cannot have an enjoyable life without enough clean water.
On one hand we should stop wasting this little water of ours,on the other hand we should find ways to reuse it,but this has not been done widely.
Today,in most large cities,water is used only once and it then returns to the sea or runs into underground places.lf we can make it clean again,it can be used once more just as if it were fresh from a spring.
But even if large cities reuse its water,we still would not have enough in the future. Where.could we turn to next for water? To the ocean! How can we do to make use of this great a-mount of sea water? We can take the salt from the water to make it fresh.
So if we take all these steps,we'll be in no danger of drying up!

A. The amount of fresh water is really very small.
B. The people of the world waste too much water.
C. The people of the world have to drink a lot of water every day.
