    　　Do you know something about tree rings（年轮）? 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 sun shines and rainfall（雨量）. And little sunshine or rain fall 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.

    (1) _________ in good climate.

    [　　]

    A．Tree rings grow far from each other.

    B．Tree rings become thinner.

    C．Trees don't need sunshine or rainfall.

    (2) The scientists are interested in studying tree rings because tree rings can tell________.

    [　　]

    A．whether a tree was strong or not

    B．whether people took good care of the trees or not

    C．whether the climate was good or not.

    (3) If you want to find out the weather of twenty years ago, you should study _______ of a tree from the outside to the inside

    [　　]

    A．the twentieth ring

    B．the tenth ring

    C．the nineteenth

    (4) Why did people usually live in places with lots of trees?

    [　　]

    A．Trees could tell the change of the weather.

    B．Trees could be used for burning and for building houses.

    C．Trees could make weather not too hot or too cold.

    (5) The people had to leave the place in New Mexico _______.

    [　　]

    A．Because bad weather stopped the growth of trees

    B．Because they no longer had water and the land became sand

    C．Because they didn't have enough trees for burning
