三、阅读理解。
根据短文内容，选择正确答案。（2007山西）
Why do we need to throw less away? There are two reasons. One is that some resources (资源) are non-renewable (不可再生的). That means there is only a certain amount of that resource in the world. One example of this is oil. When we use up all the oil in the world, there will be no more.
There is another reason for throwing less away. All of our trash has to be put somewhere. Often, it is put into garbage dumps (垃圾场). Much of that trash will be there for hundreds of years. The dumps will be filled up with all this trash.
There are three ways to cut down on trash.
One way is to recycle. When you recycle something, it means it is made into another shape and used again. Old newspapers may become paper bags. A glass jar can be melted (熔化) and made into a bottle.
Another way to cut down on trash is to reuse things. You can wash and use again a bottle that can hold mustard (芥末酱) or something else.
The third way to cut down on trash is to reduce the amount of trash you make, stop buying things that you don’t need in the first place. That reduces the amount of the earth’s resources that you use.

( ) 1. How many reasons do we need to throw less away?
A. Three. B. Five. C. Two.
( ) 2. When you reuse something, it means _______.
A. it is made into another shape and used again
B. it is used again
C. it isn’t used any more
( ) 3. All the ways of cutting down on trash in the passage are to _______.
A. recycle and reuse things
B. recycle and reduce the amount of trash you make
C. reuse things , recycle and reduce the amount of trash you make
( ) 4. If a broken plastic box is changed into a plastic ruler, the way is to _______.
A. recycle B. reuse C. reduce
( ) 5. The word “reduce” in the passage means _______.
A. 还原 B. 减少 C. 增加
