Trees are useful to man in three very important ways. The first important way is that they provide man with food, wood and other products. Trees provide not only man with food, but also many animals with food. Without trees many animals could not live on the earth. It’s not easy for man to live on the earth, either.

The second important way is that trees give us shade. On a hot summer day, people are eager(渴望)to have a rest under the shade of a tree after they have walked a long way. You can imagine how important the shade of a tree is to man and to animals.

The third important way is that trees help to prevent drought and foods. However, in many parts of the world, man has not realized the third important way. He has cut trees down in large numbers. In the end he finds that he has lost the best friends he had.

When my first wartime Christmas came, I was in basic training in New Jersey and not sure if I could make it home for the holidays. Only on the afternoon of December 23 was the list of men who would have three-day passes (通行证) posted. I was one of the lucky soldiers.

??? It was Christmas Eve when I arrived, and a light snow had fallen. Mother opened the front door. I could see beyond her, into the corner of the living room where the tree had always stood. There were lights, all colors, and ornaments (装饰物) shining against the green of a pine.

??? Where did it come from?” I asked.

??? “I asked the Gates boy to cut it,” my mother said. “I wouldn’t have had one just for myself, but when you called--- oh, such a rush! He just brought it in this afternoon…”

??? The pine reached to the proper height, almost to the ceiling, and the Tree Top Krystal Star was in its place. A few green branches reached about a little awkwardly (难看地) at the side, I thought, and there was a bit of bare trunk showing in the middle. But the tree filled the room with warm light and the whole house with pleasant smell of Christmas.

??? “It’s not like the ones you used to find,” my mother went on. “Yours were always in good shape. I suppose the Gates boy didn’t know where to look. But I couldn’t be picky.”

??? “Don’t worry, ” I told her. “It’s perfect.”

??? It wasn’t, of course, but at the moment I realized something for the first time: all Christmas trees are perfect.

A tree over a hundred years old means that it has more than a hundred   6  . When the climate is dry(干燥的) or very cold, the trees do not grow very much and their rings are usually   7  . When it is wet and   8  , the rings are much thicker. If the rings are suddenly very thin or suddenly very thick, this means that the    9   changed suddenly.

It’s important to learn about protecting our environment. Here is a 5R rule for us:

1. Reduce

If you want to reduce waste, you should use things wisely. Millions of trees are being cut down to make paper. If everyone uses a little paper carelessly and throw it out, soon we would not have any trees left. Other things are also being wasted, and people don’t know what to do with the waste in big cities. So it is necessary to reduce the waste

2. Reuse

You should always think of reusing the usable things before throwing them out. Give your clothes you do not use or the ones which are too small to the poor. With a family, you may pass on such clothes to younger brothers or sisters.

3. Recycle

Bottles, cans and paper can easily be recycled. By doing so, we save lots of time and money. For example, coke cans are sent to a factory, where they are smashed flat(压平)and melted (融化) and the melted things are made for new coke cans.

4. Recover

When you buy a box of apples, there may be a few rotten(腐烂的)apples. You have two choices: one is to throw the whole apple away, or you could cut off the rotten parts and eat the good parts. In this way, you are recovering the eatable parts of food.

5. Repair

If one of the legs of your table is broken, you can repair it instead of throwing it away. If you want to change for better ones, It is better for you to sell the old things or give them to other people who can use them after doing some repairs. It is true that North America is a “throw-away” society(社会). But the time has come to change our way of life so that we can protect our environment. Every one of us should try our best.

1._______ can be recycled.

A.Only hard things    B.Many things        C.Few soft things     D.All things

2.The “recover” rule mainly requires us _______.

A.to throw waste things away                B.to cover waste things with earth

C.to get back the useful parts                D.to throw the whole things away

3.We can infer(推断) that the writer of this passage may live in _______.

A.China            B.Japan             C.Australia          D.America
