英语翻译
Everyone may know tree rings tell us how old a tree is.But do you know they can tell us what the weather was like?
A tree grows well in a climate (气候) with lots of sunlight and rainfall (雨量).And little sunshine or rainfall limits (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,you can count the rings of a tree from the outside to the inside.If the tenth ring is far from the eleventh ring,then we are sure that it was sunny and rainy most of that year.If it is near to the eleventh ring,then the climate of that year was bad.
众所周知,树木的年轮可告知我们他们的年龄.可你是否了解,通过年轮,我们还可以判断气候状况呢?
拥有充足光照和雨量的气候有利于树木的生长,缺少光照和雨水则限制树木的成长.通过研究树木的年轮,我们可以得知气候的变化.例如,想知道10年之前的气候状况,从外到里数树木的年轮,如果第十圈与第十一圈的距离很远,那么我们可以确定当年光照与降雨量均很充足.如果第十圈距第十一圈很近,则说明当年的气候很糟糕.
