The world is not only hungry, it will also be thirsty for water. About 97% of water on the earth is sea water, or salty(咸的) water. Man can only drink or use the other 3% of the fresh water(淡水) which comes from rivers, lakes and underground.
The sea is very big. Look at the map of the world, there is more sea than land. It covers(覆盖) quarters of the earth, it looks very beautiful when the sun is shinning on it. But it can be terrible when there is a strong wind. Some parts of the sea are very deep. There is one place near Japan. It's nearly 11 kilometers high. If we put that mountain into the sea at that place, there would be 2 kilometers of water above it!
The sea is salty. There is one "sea" called the Dead Sea. The Dead Sea is not a sea. It's a big lake in the Jordan Valley. It's the saltiest. It's near the city of Jericho. It's about 80.kilometres long, between 4.8 and 17.7 kilometers wide. The river Jordan runs into the Dead Sea. The sun is not there and the water is salty. Fish can't live in the Dead Sea and plants can't grow near it. People can't swim well in the Dead Sea, but they can float(漂浮) on the water. The water is very blue and the air is clean. In winter, people come to the Dead Sea to enjoy the sunshine.
1.Does the fresh water come from rivers, lakes and underground?
A. Yes, it does. B. No, it doesn't.

The world is not only hungry, but it is also thirsty for water. This may seem strange to you, since nearly 70% of the earth’s surface is covered with water. But about 97% of that is sea water or salt water. Man can only drink and use the other 3% fresh water from rivers, lakes，underground and other sources. And we can not even use all of that. Even worse, some of it has been made dirty.
However, as things stand today, this fresh water is still enough for us. But our need for water is becoming 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(缺少)later on.
We all have to learn how to stop wasting our valuable water. One of the first steps is to develop 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 steps we’ll be in no danger of drying up.

The world is not only hungry but also thirsty for water. This may seem strange to you, since nearly 70% of the earth’s surface is covered with water. But about 97% of that is sea water or salt water. Man can only drink and use the other 3% of fresh water from rivers, lakes, underground and so on. 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 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 clean 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 is used only once and then sent 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.
1.The world is thirsty for water because _______.
A. we don’t have enough fresh water B. a lot of water goes into sewer systems
C. only 70% of the earth’s surface is water D. sea water is widely used rather than fresh water
2.From this passage, we know acid rain _______.
A. is only bad for living things B. is not bad for buildings and factories
C. can be produced in factories D. is bad for people, animals, plants and buildings
3.One difficult way we can solve the problem is to _______.
A. use the water with salt in it B. remove the salt from sea water
C. get water from underground D. reuse the water in cities
4.What is the best title for this passage?
A. Fresh water and sea water B. A thirsty country
C. The importance of water D. The world’s water problem

The world is not hungry， but it is thirsty. It seems strange that nearly 3/4 of the earth is covered with water while we say we are short of (短缺) water. Why? Because about 97% of water on the earth is sea water which we can’t drink or use for watering plants directly. Man can only drink and use the 3%--- the water that comes from rivers and lakes. And we can’t even use all of that， because some of it has been polluted.
Now more water is needed. The problem is: Can we avoid a serious water shortage (短缺) later on?
First we should all learn how to save water. Secondly， we should find out the ways to reuse it. Scientists have always been making studies in the field. Today， in most large cities water is used only once and then runs to the sea or rivers. But it can be used again. Even if every large city reused its water， still there would not be enough. What could people turn to next?
The sea seems to have the best answer. There is a lot of water in the sea. All that needs to be done is to get the salt out of the sea water. This is expensive， but it’s already used in many parts of the world. Scientists are trying to find a cheaper way of doing it. So you see， if we can find a way out， we’ll be in no danger of drying up.

(C)The earth is not only, but also thirsty for water. This may seem strange to you. because nearly 70% of the earth’s surface（表面）is covered with water. But about 97% of that is sea water, or salt water. Man can only use the other 3%—the fresh water from rivers, lakes, and other sources. And we can’t even use all of that, because some of it is in the form of icebergs and glaciers（冰川）. Even worse, some of it has been polluted.
However, as things stand today, the fresh water is still enough for us. But our need for water is becoming 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 later on.
