How do you read rings?
Look at a log.It was once a tree.And it has a story to tell.
The story isn't in words,but in rings.You can read the story.This isn't difficult to do.You have to know how trees grow.
In warm months trees grow fast.In cold months they don't.The woods grow in layers(层).Each year makes a layer.
Look at the end of the log where the saw cut.The saw cut through the layers.Each layer makes a ring.There is one ring for each year.
Count the rings and you'll know how old the tree was.A thick ring shows a good year.The tree grew a lot.A thin ring shows a bad year.Maybe it was too cold or dry and the tree didn't grow very much.
So when you see a log,look at the end .Read the rings.They tell the story of the tree's life.

你是如何观察年轮的?
看这段木头,它曾经是一棵树,它蕴涵着一个故事可讲.
这故事并不是用语言来讲的,而是通过年轮.你可以读懂这个故事,它并不难读懂.但你必须知道树是如何生长的.
在温暖的日子里树长得很快,而在寒冷的日子里它们长得慢,树木一层层地生长,它每年都会长出一层.
看看树木底端被锯子截断的地方,锯子截断了层层的树木,每一层都(制作?造就?印出?找不出合适的词呐)了一圈年轮,所以每年都会有一圈年轮.
数数年轮你就会知道这棵树有多"大"了.一圈厚厚的年轮代表着气候情好的一年.树长了很多.一圈薄薄的年轮意味着气候恶劣的一年.或许气候太冷或太干所以树长势不很好.
所以当你看到一棵树时,看看它的根部.观察年轮,它们讲述了树的生长故事.
终于翻完呐,纯人工翻译哦,吼吼==
