英语翻译
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 of the weather even further back.
It is clear that a tree would grow best in a climate with lots of sunlight and rainfall.It is also expected that little sunlight or rainfall would limit the growth of a tree.The change from a favorable to an unfavorable climate can be seen by reading the tree rings in a tree trunk.To find out the 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 rings 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 of 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.

想知道天气的历史吗?别看天,别翻旧天气预报.有用的是看看树的年轮.一些天气报告只是前一个世纪的,但是有些树却能给我们展示更久远的天气记录.
很明显,在阳光明媚雨量充沛的天气里树生长得最好.而正如所料在阳光稀少的旱季树木的生长将受到限制.看树干的年轮就能够知道最适宜与最不适宜天气之间的变化.想知道十年前的天气的话,由外向内数数树干的年轮.
如果第十圈年轮距离其他年轮很远,那么我们就可以肯定十年前阳光明媚而且雨量充沛.如果年轮相距很近,那这棵树的生长气候就很糟.
研究树的年轮不仅对气候历史重要,而且对人类的历史也很重要.在新墨西哥州的某个地方,那里只有沙子——没有树木也没有人烟.但是,数个世纪以前那里人口密集.然后他们突然离开了.为什么?
有科学家研究了那儿的死树的年轮.他发现人们不得不离开因为他们砍完了所有的树用来取暖跟造房子.一旦树木砍伐殆尽,他们就不得不离开了.
