Do you want to know something about the history of weather? Don’t look at the sky. Don’t look for old weather reports. Looking at the tree rings is more important. Some weather reports go back only one century, but some trees can show us an exact record(记录) of the weather even further back.
It is clear that a tree would grow best in a climate(气候) with lots of sunlight and rainfall. It is also expected that little sunlight or rainfall would limit(限制) the growth of a tree. The change from a favorable(有利的) to an unfavorable climate can be seen by reading the tree rings in a tree trunk(树干). To find out he weather of ten years ago, count the rings of a tree trunk from the outside to the inside. If the tenth ring is far from the other rings, then we are sure that lots of sunny and rainy weather happened. If the ring are close together, then the climate was bad for the tree.
Studying tree rings is important not only for the history of weather, but also for the history of man. In a place of New Mexico you can find only sand — no trees and no people. However, many centuries ago a lot of people lived there. They left suddenly. Why?
A scientist studied the dead tree rings which had grown there. He decided that the people had to leave because they had cut down all the trees. Trees were used to make fires and buildings. So, after the people cut down the trees, they had to move.
1. It is understood that in a favorable climate ____________ .
A. tree rings grow close together. B. people can cut down most o the trees
11
in New Mexico.
C. tree rings grow far from each other. D. trees in New Mexico will grow big and tall.
2. Why did people usually live in the place where there were lots of trees?
A. Trees could record the change of the weather. B. Trees brought lots of sunlight and rainfall.
C. Trees were used for burning and building houses. D. Trees gave them fruit and food.
3. The scientists are interested in studying tree rings because they can tell ___________ .
A. whether in that place the climate was favorable or not. B. whether a tree was healthy or not.
C. Whether people took good care of the trees or not. D. how old the trees were.
4. Studying dead tree rings shows ___________ .
A. where the people had to go. B. what the people had to eat.
C. how the people left. D. why the people had to leave.
5. The people had to leave the place of New Mexico because ___________ .
A. they had cut down all the trees. B. there were many trees there.
C. there and no water. D. bad weather stopped the growth of trees.

The world is not only hungry, it will also be thirsty for water. This may seem strange to you, since about 75 percent of the earth’s surface(表面) is covered with water. But about 97 percent of this huge amount(数量) is seawater, or salt water. Man can only drink and use the other 3 percent—the fresh water that comes from rivers, lakes, underground and other sources. But, unluckily, some of it has been made dirty and is unfit for drinking.
However, as things stand today, this small amount of fresh water is still enough for us. But our need for water increasing(增加) very quickly, almost day by day. Only if we take steps to deal with this problem now can we keep away from a serious worldwide water shortage(短缺) later on. So we all have to learn how to stop wasting our precious(珍贵的) water.

What do we really mean by being open? Being open is a kind of invitation to others to come in, to speak and to share. It is important for others to get to know how we think and feel. In this way, we will be understood and accepted by others. If we aren’t open
11
with others, we won’t fully believe in ourselves or others.
Here are a few ways for you to be more open. First, make your outside behavior the same as your inside feelings and thoughts. Second, share how you really feel about something instead of just opinions. Third, try to change your questions into statements(陈述句) and talk in the first person so that people will understand you more easily. For example, you might say, “I feel happy that you’re here.” instead of“Are you glad that you’re here?” Finally, try not to say, “I don’t know.” This usually means I don’t want to think about it any more.
Remember also that it is not suitable to be open with everyone in every situation. You may want to be more open with close friends, but not with people you don’t know well, because you are not sure how someone else will use what they know about you. Besides, some people may not be used to too much openness. If we say everything we feel or think to them, they will feel very uncomfortable at times.
In all, being open is a good way for us to get on well with other people, but we’d better keep the balance(平衡) between being open and not being too open.
Title: Being _______1______

Writing a thank-you letter can be a great way to express thanks for a favor (帮助；恩惠) someone did for you. Consider these following steps when writing your letter, which will help make your thank-you letter more meaningful and sincere(真诚的).
Before you start, buy some special stationery, such as nice paper or blank cards. The stationery doesn’t have to be expensive, since even one-dollar card can be very nice. And you must decide whether you prefer to type your letter or write it by yourself. Handwriting has a more personal feeling, while a printed thank-you letter looks more professional (专业的).
Now, you can start writing. You should express your purpose from the beginning. Start your letter by thanking the person for the gift or service he or she provided. Then you should explain how you plan to use the gift or service, or explain how the gift or service has already been used. What’s more, you can also express your feelings on the gift or service by saying that “It was a wonderful birthday present…” It also helps to mention a personal feeling such as “I was just so happy with the party.” In the end, you should mention that you want to see or talk to the person again soon. For close relatives and friends, you can also tell them how much you miss them and express regret(遗憾) that their visit was short.
11
Sign your thank-you letter personally and with a heart. Try “Love”, “Yours truly”, or “Take care” instead of “Sincerely” as it is more for business.
In this way, you will always maintain (维持) a pleasant relationship(关系) with your friends and relatives. Title: How to Write a 1 Letter
Purpose
To write a 2 and sincere letter to show your thanks.
