We know that trees are useful in our everyday life. They give us   1  things, such as wood, oxygen, rubber(橡胶), medicines   2  many other things. They can also tell us a lot about our climate. The following are the reasons. If you cut   348  a tree, you can see that it has many rings. Most trees grow one new ring   4  year. Because of this, we know how old a tree is. A tree over a hundred   5  means that it has more than a hundred   6 . When the climate is dry or very cold, the trees do not grow very much and their rings   7  usually thin. When it is wet and warm, the rings
8  thicker. If the rings are suddenly very thin or suddenly very thick, it means that the 9  changed suddenly. If we look at the rings on the tree, we can learn about the climate in the past years. We can see
  10  changing today.
