单选题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.

单选题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 centre. Faces, like fingerprints, are unique. Did you ever wonder how it is possible for us to recognize people? Even a skilled writer probably could not describe all the features that make one face different from another. Yet a very young child—or even an animal, such as a pigeon—can learn to recognize faces. We all take this ability for granted. We also tell people apart by how they behave. When we talk about someone's personality, we mean the ways in which he or she acts, speaks, thinks and feels that make that individual different from others. Like the human face, human personality is very complex. But describing someone's personality in words is somewhat easier than describing his face. If you were asked to describe what a "nice face" looked like, you probably would have a difficult time doing so. But if you were asked to describe a "nice person", you might begin to think about someone who was kind, considerate, friendly, warm, and so forth.
