dont look at the sky. dont 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 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.bthe world is not only hungry, it will also be thirsty for water. this may seem strange to you, since about 75 percent of the earths 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 percentthe 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.1. in the first line of the passage “the world” means _ .a. all the people b. all living things c. the earth d. the universe2. according to the passage man can only use _ .a. about 75% of the earths water. b. about 97% of the earths water. c. exactly 3% of the earths water. d. about 3% of the earths water.3. all the fresh water _ .a. is good enough to be used. b. is polluted and cant be drunk. c. can not be used by man, as some of it has been polluted. d. comes from oceans, rivers and lakes.4. which of the following is true according to the passage?
