We know that trees are useful in our everyday life. They 31 us many things such as wood, oxygen (氧气), rubber (橡胶), medicine and so on. They can also 32 us a lot about our climate (气候).

When it is wet and warm, the rings are much thicker. If the rings are suddenly very thin or suddenly very thick, this 38 that the climate changes suddenly. For example, we can observe (观察) the rings of a tree to 39 out the weather of ten years ago. If the tenth ring is far from the 40 ring, then we're sure it was sunny and rainy most of that year. 41 it is near to the eleventh ring, then the climate was bad that year. So if we look at the rings on a tree, we can learn 42 the climate in the past years.
A tree 43 grow well in a climate with lots of sunshine and rainfall. And little sunshine or rainfall is 44 for the growth (生长) of the trees. The tree rings can tell us the history of weather. We can see 45 our climate is changing today.
