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 tree rings is more important. Correct weather reports date back only one century, but some trees can provide an exact record of the weather even further back.It is natural that a tree would grow best in a climate with plenty 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 determined by reading the pattern of 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 it is certain that plenty of sunny and rainy weather occurred. 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 for the history of man. In a region of New Mexico you can find only sand--no trees and no people. However, many centuries ago a large population lived there. They left suddenly. Why?A scientist studied patterns of 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 necessary to make fires and buildings. So, after the people destroyed the trees, they had to move.In this instance studying tree rings uncovered an exciting fact about the history of man.【小题1】It is understood that in a favorable climate____________.A．tree rings grow close togetherB．tree rings grow far apartC．trees in New Mexico will grow big and tallD．people can cut down most of the trees in New MexicoA．Trees provided them with shades.B．Trees indicated plenty of sunlight and rainfall.C．Trees were materials for cooking and building houses.D．Trees provided them with fruit and food.A．a lot about what happened in history.B．whether a particular tree was healthy or not.C．whether people took good care of the trees or not.D．how old the trees were.A．where the people had to goB．what the people had to eatC．how the people leftD．why the people had to leaveA．they had cut down all the treesB．there were many trees thereC．they had no waterD．bad weather stopped the growth of trees【小题2】Why did ancient people usually live where there were plenty of trees?A．Trees provided them with shades.B．Trees indicated plenty of sunlight and rainfall.C．Trees were materials for cooking and building houses.D．Trees provided them with fruit and food.【小题3】Scientists are interested in studying tree rings because they can tell__________.A．a lot about what happened in history.B．whether a particular tree was healthy or not.C．whether people took good care of the trees or not.D．how old the trees were.【小题4】By studying the dead tree rings in Mexico the scientist found out____________.A．where the people had to goB．what the people had to eatC．how the people leftD．why the people had to leave【小题5】The people had to leave the region of New Mexico because__________.A．they had cut down all the treesB．there were many trees thereC．they had no waterD．bad weather stopped the growth of trees
