？ 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's 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 (有利的) to an unfavorable climate can be reading the tree rings in 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 the 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.
