　　Ask three people to look out the same window at a busy street corner and tell you what they see. Chances are you will receive three different answers. Each person sees the same scene, but each perceives something different about it.

Another may say that he sees a rush-hour traffic jam at the crossing. The third may tell you that he sees a woman trying to cross the street with four children. For perception is the mind? s explanation of what the senses --- in this case, our eyes --- tell us.

　　Many psychologists today are working to try to decide just how a person experiences or perceives the world around him.

　　Questions 21-25 are based on the following passage:

　　Not all heroes are to be found in the army. Some of them are to be found in other fields of life.

　　Early in this century, a group of doctors was trying to discover the cause of the dangerous disease called yellow fever. At that time it was one of the worst diseases known, thousands of people were dying of it every year.

　　It had been suggested that the disease was caused by the bite of a certain mosquito. That is, it was thought that a certain kind of mosquito would bite a person ill with yellow fever and then, flying elsewhere, bite another person and give him the disease.

　　To prove whether or not this was true, one of the doctors, Dr. James Carroll, allowed such a mosquito to bite him after it had bitten a yellow fever patient. He knew that the bite of this mosquito might cause his death, but he made the trial.

　　Dr. Carroll became very ill with yellow fever but finally recovered. The risk this hero took, however, helped to save the lives of many thousands of people. He had proved that yellow fever is carried by a mosquito.

　　Questions 26-30 are based on the following passage:

　　In science the meaning of the word “explain” suffers with civilization? s every step in search of reality. Science cannot really explain electricity, magnetism , and gravitation; their effects can be measured and predicted, but of their nature no more is known to the modern scientist than to Thales who first looked into the nature of the electrification of amber, a hard yellowish-brown gum.

　　Most contemporary physicists reject the notion that man can ever discover what these mysterious forces “really” are. Electricity, Bertrand Russell says, “is not a thing, like St. Paul? s Cathedral; it is a way in which things behave. When we have told how things behave when they are electrified, and under what circumstances they are electrified, we have told all there is to tell.” Until recently scientists would have disapproved of such an idea. Aristotle, for example, whose natural science dominated western thought for two thousand years, believe that man could arrive at an understanding of reality by reasoning form self-evident principles. He felt, for example, that it is a self-evident principle that everything in the universe has its proper place, hence one can deduce that objects fall to the ground because that? s where they belong, and smoke goes up because that? s where it belongs. The goal of Aristotelian science was to explain why things happen. Modern science was born when Galileo began trying to explain how things happen and thus originated the method of controlled experiment that now forms the basis of scientific investigation.��

　　26. The aim of controlled scientific experiments is ____.

　　A. to explain why things happen��

　　B. to explain how things happen��

　　28. Bertrand Russell? s notion about electricity is ____.

　　A. disapproved of by most modern scientists��

　　B. in agreement with Aristotle? s theory of self-evident principles��

　　C. in agreement with scientific investigation directed toward “how” things happen��

　　D. in agreement with scientific investigation directed toward “why” things happen��

　　29. The passage says that until recently scientists disagreed with the idea ____.

　　A. that there are mysterious forces in the universe��

　　B. that man cannot discover what forces “really ” are��

　　C. that there are self-evident principles��

　　D. that we can discover why things behave as they do��

　　30. Modern science came into being ____.

　　A. when the method of controlled experiment was first introduced��

　　B. when Galileo succeeded in explaining: how things happen��
