25、 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, underground 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. If 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 amount 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!
1. Why does the writer say that the world is thirsty for water?
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.
D. There are too many people in the world needing water.
2. From the passage we know that fresh water doesn’t come from _________.
A. rivers B. lakes C. underground D. the sea
3. The underlined word shortage in the second paragraph means _______in Chinese.
A. 问题 B. 短龄 C. 缺乏 D. 资源
4. The writer thinks that people in large cities should __________.
A. stop the used water from getting into underground
B. only use the water from the rivers
C. make their used water clean again
D. use as much sea water as possible
5. In order to solve the problem of water shortage, we have to __________.
a. make use of sea water on the earth.
b. save as much fresh water as possible
c. reuse the water from large cities
d. stop people from using too much water
e. only use the 3% of the water on the earth
A. a and e B. a, b and c C. b, c and d D. a, b and d

Man can only use the other 3% the fresh water from rivers, lakes, underground, and other sources (源泉).
And we can not even use all of that. Even worse, some of it has been made dirty.

larger and larger quickly-almost day by day. We should take steps to do with this problem now and in this
way we can get away from a serious world-wide water shortage (缺乏) later on.
We all have to learn how to stop wasting (浪费) our valuable water. One of the first steps is to develop
(开发) ways of reusing it. Today in most large cities, water is used only once and then sent out into a sewer
system(下水道). From there it returns to sea or runs into underground places. But even if every large city
reused its water, we still would not have enough. All we'd have to do to make use of sea water in the world
is to remove the salt. If we take these we will be in no danger of drying up.

And we can not even use all of that because some of it has been made dirty.
Earth Day is April 22. But on all other days, we must also remember how important water is. The water that we use is the most important natural resource on the earth. Today we face serious water problems. One of them is water pollution. All kinds of things from cars, factories, farms and homes make our rivers, lakes and oceans dirty. Polluted water is very bad for people to drink. And dirty water is bad for fish, too.
How do cars and factories make our water dirty? First they pollute the air. Then when it rains, the rain water makes our drinking water dirty. Dirty rain, called acid rain（酸雨）, is also bad for plants, animals and buildings. Scientists say that in 30 years, more than half of the people in the world won't have enough dean water. We have to learn how to stop wasting water. One of the first steps is to develop ways of reusing it. Today in most large cities, water i~ used only once and then sere out into a sewer system（下水道）. From there it returns to the sea or goes underground.
But even though every large city reused its water, we would still not have enough. So we should make use of sea water by removing the salt in it. If we can take these steps, fresh water won't be used up.
