阅读理解

　　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％ the 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 of 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. 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 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 longer danger or drying up.

(1) The world is thirsty for water because ________.

[　　]

A. man hasn't got enough food to eat

C. only 70％ of the earth's surface is water

(e) Drink and use all the water on the earth's surface.

[　　]

(4) The best but the most difficult way to solve the water problem of the world is to ________.

[　　]

A. remove the salt from the water

B. make the water in cities clean

C. take water from underground

D. make the need for water smaller

The Tree of Life

　　Two travelers are walking in Africa. The sun beats down on them. The land is dry and dusty. Even the rivers have dried up.

　　The travelers sit down next to a huge, ugly tree. They're hot and tired. Most of all, they're thirsty. They reach for their water canteen (水壶) . It's empty! Where can they find water? They look up at the tree next to them. Then they remember. Quickly, they climb to the top of the tree. They find a scooped-out hole there. The hole is filled with water. The travelers take huge gulps. The baobab (木棉) tree has saved their lives.

　　The baobab tree is a funny-looking tree. Its bark (树皮) is wrinkled (超皱) and looks like elephant skin. The branches look like roots reaching for the sky. But this strange tree has saved the lives of people and animals. The tree stores enough water at the top to last for many months. Animals use the tree as a drinking fountain (水源). Some animals even move in and live among the roots. The animals can stay for a long time. Some baobab trees live for 2000years.
