Trees are one of the oldest“citizens(公民)”of our Earth．They keep our air clean,。Reduce noise pollution，improve water quality(质量)and provide food and building materials．

Just like us, trees change a lot as they grow．At one to three years old, young trees learn how to protect themselves．For example，many trees grow thorns(刺)to warn animals not to go near. Most young trees have large，deep green leaves so that they can catch enough sunlight and change it into their food and energy.

当小树成长到四年的时候，它们成长可是加速并且进一步强壮，以足以面对未来生命中的挑战At the age of l5，trees become young adults．They grow more slowly and begin to produce flowers and fruit．

It is not until山e tree is 20 to 25 years old that it becomes a real adult. The tree reaches its 1argest．Not only does the adult tree give us shade，oxygen(氧气)and natural beauty；it is also a great place for a tree house，or a place for us to nap，read a book，listen to music or sip(小口喝)tea．If we give the adult tree proper care，it will continue to live healthily for many years.

Gradually(渐渐地)，trees begin to grow older and older and even die．At this time，they still have their important place in nature．When a tree becomes hollow(空心的)or part of it becomes dead．it provides a home to small animals and is a source of food for many other animals.

In many ways．the life of a tree is similar(相似的)to our own life experience. When we are looking at the life of a tree , we learn about that each period of life brings its own form of joy and challenge．Enjoy every minute of the life of the trees and take care of the trees!

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.

??? “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.”

We know that trees are useful in our everyday life. They 1 us many things, such as wood, oxygen(氧气), rubber, medicines and many other things. They can 2 tell us a lot about our climate. The following are the reasons. If you cut across a tree, you can 3 that it has many rings. Most trees grow one 4 ring every year. Because of this reason, we know 5 a tree is. 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. If we look at the rings on the trees, we can 10 about the climate for a hundred years. We can see how our climate is changing today.

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

Trees are useful to man in three important ways.

The first important way is that they provide(提供) man with food, wood and the 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(阴凉). On a hot summer day, people are eager(渴望) to have a rest under the tree after they have a long walk. You can imagine how important the shade of a tree is to man and animals.

The third important way is that trees help to prevent droughts and floods(防止干旱和洪水). However, in many parts of the world, man hasn’t realized the third way. They were cutting trees down in large numbers. In the end they find that they have lost the best friends they had.
