Task 1 Directions:After reading the following passage,
you will find 5 questions or unfinished statements, numbered 36 through 40. For
each question or statement there are 4 choices marked A, B, C and D. You should
make the correct choice and mark the corresponding letter on the Answer Sheet
with a single line through the center.
Do you want to know something about the
history of weather Don’t look at the sky. Don’t look for old weather reports.
Looking at tree rings is more important. Correct weather reports date back only
one century, but some trees can provide an exact record of the weather even
further back. It is natural that a tree would grow best in a
climate with plenty of sunlight and rainfall. It is also expected that little
sunlight or rainfall would limit the growth of a tree. The change from a
favorable to an unfavorable climate can be determined by reading the pattern of
rings in a tree trunk. To find out the weather of ten years ago, count the rings
of a tree trunk from the outside to the inside. If the tenth ring is far from
the other rings, then it is certain that plenty of sunny and rainy weather
occurred. If the rings are close together, then the climate was bad for the
tree. Studying tree rings is important not only for the history of weather, but
also for the history of man. In a region of New Mexico you’ can find only
sand-no trees and to people. However, many centuries ago a large population
lived there. They left suddenly. Why A scientist studied
patterns of dead rings which had grown there. He thought that the people had to
leave because they had cut down all the trees. Trees were necessary to make
fires and buildings. So, after the people destroyed the trees, they had to
move. In this instance, studying tree rings uncovered an
exciting fact about the history of man.
The scientists are interested in studying tree rings because they can tell ______ .
A．whether in that area the climate was favorable or not B．whether people took good care of the trees or not C．whether a particular tree was healthy or not D．whether a particular tree were
