Do you know something about tree rings(车轮)? 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(气候)with lots of sunshine and rainfall (雨量). And little sunshine or rainfall will limit (限制) the growth of a tree. We can see the change of climate 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.

你知道树的年轮吗?你知道他们可以告诉我们什么的天气怎么样,有时甚至是几百年以前的事了?
一树将在一个良好生长的阳光和雨水很多气候.和小阳光或降雨将限制了树木的生长.我们可以看到通过研究树木年轮气候变化.例如,要找出十年前的天气,计数从外面一棵树的戒指里面.如果十环远离十一环,则我们相信,这是晴天和阴雨当年最.如果是靠近十一环,则是这一年的气候恶劣.
树木年轮不仅是重要的研究历史,但天气也为研究人类的历史.许多世纪以前,有一个住在新墨西哥州举行了很多人.但现在你可以发现那里只有沙子,没有树木,没有人.发生了什么事?科学家研究了环有死树.他发现,人们不得不离开,因为他们砍伐了所有的树木和建筑物,使大火.由于所有的树木已经走了,那里的人不得不搬迁.

你知道树的年轮吗?你知道他们能告诉我们天气怎么样,甚至是几百年前的天气?
在阳光充足,雨量充沛的条件下,树会长得很好,阳光和与量少则会限制树的生长。通过研究树的年轮,我们可以知道当时气候的变化。例如,要弄清10年前的天气状况,可以从外向里数年轮,如果第十环里第十一环很远,那么我们可以肯定那年大多数时候是晴朗的,雨量也很充沛。如果离第十一环很近,那气候就很糟糕。

你知道树的年轮吗?你知道他们能告诉我们天气怎么样,甚至是几百年前的天气?
在阳光充足,雨量充沛的条件下,树会长得很好,阳光和与量少则会限制树的生长。通过研究树的年轮,我们可以知道当时气候的变化。例如,要弄清10年前的天气状况,可以从外向里数年轮,如果第十环里第十一环很远,那么我们可以肯定那年大多数时候是晴朗的,雨量也很充沛。如果离第十一环很近,那气候就很糟糕。
年轮不仅对研究历史上的天气很重要而且对研究历史上的人也很重要。很多个世纪之前,在新墨西哥住着一群人,但现在你在那儿只能看到沙子,没有树也没有人。发生了什么呢?一位科学家研究了那里死树的年轮,他发现那里的人不得不离开,因为他们砍到了所有的树来生火和建造建筑物。由于所有的树都没有了,那里的人不得不离开。
