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 tings, then it is certain that plenty of sunny and rainy weather occurred. If the tings are close together, then the climate was bad for the tree.
Studying tree tings 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.
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 tings uncovers an exciting fact about the history of man.
The people had to leave the region of New Mexico because ________.
选项
A、they had cut down all the trees
B、there were many trees there
C、they had no water
D、bad weather stopped the growth of trees
