【题目】 Why do we need to throw less away? There are two reasons. One is that some resources(资源) are nonrenewable(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 newspaper 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 thing that you don’t need in the first place. That reduce the amount of the earth’s resources that you use.

1How many reasons do we need to throw less away?

______________________________________________

2Will the dumps be filled up with all this trash?

【题目】 In the 13th century, Marco Polo, the world known Italian traveler saw many wonderful things in China. One of the things he discovered was money made of paper. People in the West did not have such kind of money until the 15th century. However, the Chinese began to use it in the 7th century.

Paper was invented by a Chinese man called Cai Lun almost 2,000 years ago. But it was not made in Europe until the year 1100. Four hundred years later, a German discovered that he could make the best paper from trees. After that countries rich in forests, such as Canada, Sweden, America, Finland became the most important ones in paper making.

Paper can be used in many ways. The common uses include newspapers, magazines and books. But do you know that paper can be used for keeping warm? In Finland, the farmers wear paper boots to keep their feet warm in the snow. And even houses can be insulated(使绝缘) from heat or cold with paper.

However, we have to understand that paper still comes from trees now. If we keep on wasting so much paper, there will not be any trees left on the earth someday in the near future. Every day people throw away about 2800 tons of paper in our city. It takes 17 trees to make one ton of paper. This means that we are cutting down nearly 48000 trees every day. The fact is that it takes more than 10 years for a tree to grow.

So we must start saving paper right now. We can use both sides of every piece of paper. We can make useful things out of used paper. We can use china cup instead of paper ones. When shopping, we can use fewer paper bags and reuse them if we have some.

In short, we should keep a balance between using paper and protecting trees, and do it now before it is too late.

1People in China began to use paper in ________.

A.the 5th centuryB.the 6th centuryC.the 7th centuryD.the 15th century

4According to the passage, ________ trees are needed to make one ton of paper.
