Question

【題目】Do you know something about tree rings? Do you know they can tell us what the weather was like, sometimes even hundreds of years ago?

A tree will grow well in a climate with lots of sunshine and rainfall. And little sunshine or rainfall will limit the growth of trees by studying the tree rings. For example, to find out the weather of ten years ago, count the rings of a tree from the outside to the inside. If the tenth ring is far from the eleventh ring, then we’re sure that it was sunny and rainy most of that year. If it is near to the eleventh ring, then the climate that year was bad.

Tree rings are important not only for studying the history of weather but also for studying the history of man. Many centuries ago, there lived a lot of people at a place in New Mexico. But now you can find only sand there－no trees and no people. What happened?

A scientist studied the rings of dead trees there. He found that the people had to leave because they had cut down all the trees to make fires and buildings. As all the trees had gone, the people there had to move.

【解析】

試題分析：這篇文章主要告訴我們樹的年輪能幫助我們研究天氣與人的歷史。樹的年輪能告訴我們氣候是好還是壞，在好的氣候下樹的年輪間隔大。

【1】B細(xì)節(jié)理解題。據(jù)文章If the tenth ring is far from the eleventh ring, then we’re sure that it was sunny and rainy most of that year. If it is near to the eleventh ring, then the climate that year was bad.可知，根據(jù)這篇文章，樹的年輪能告訴氣候是好還是壞。故正確答案為B。

【2】A判斷推理題。根據(jù)For example, to find out the weather of ten years ago, count the rings of a tree from the outside to the inside. If the tenth ring is far from the eleventh ring, then we’re sure that it was sunny and rainy most of that year. If it is near to the eleventh ring, then the climate that year was bad.可知，如果你想查出20年前的天氣，你應(yīng)該研究第20道年輪。故該題正確答案為A。

【3】B猜測詞義題。根據(jù)第二段可知，劃線單詞“l(fā)imit”的意思是限制。即該題選B。

【4】B判斷推理題。根據(jù)If the tenth ring is far from the eleventh ring, then we’re sure that it was sunny and rainy most of that year. 可知，在不好的氣候下樹的年輪長得間隔大，故B項(xiàng)內(nèi)容錯(cuò)誤。

【5】C主旨大意題。通讀全文并根據(jù)Tree rings are important not only for studying the history of weather but also for studying the history of man. 可知，這篇文章主要告訴我們樹的年輪能幫助我們研究天氣與人的歷史。故正確答案為C。
