26、第二篇 The Structure of the Brain When you refer to your brain, you should probably say ’brains’. Most modern s cientists studying the brain have concluded that there are three major parts of ou r brain, that each is separate from the others, and that each has its own functi on and different processes. Brain 1 includes the spinal cord, the medulla ? Which sites directly on the t op of the cord ? And the middle section of the brain. It includes the controls for involuntary functions like breathing and digestion. Brain 2 is an area surrounding brain 1. In this s***nd brain are the various glands located in the brain, such as the pituitary and amygdala. Scientists studyi ng brain 2 are convinced that human emotions such as excitement, fear, and love are centerd here, as well as the senses of taste and smell. Memory and learning are also controlled by brain 2. Brain 3 is the neocortex, the thick covering that surrounds the top and side portions of the brain. This is the ’gray matter’ we often think of when we speak of the brain. Only the higher orders of animals have brain 3, and none is as hig hly developed as the human neocortext. Brain 3 sends information from the other two brains to the body and receives data from the body. It is brain 3 that makes us fully human. Brian 3 allows us to stand erect, to see, to speak, to write, t o use symbols and tools, and to remember. Brain 3 also acts as a unifying contro l of the other two brains. As scientists continue to study the brain, they disco ver specific areas that control particular functions of the body and particular emotions.This passage is mainly about____
A.he functions of the three sections of the brain.
B.the human brain.
C.complexity of the human brain.
D.the areas that control different kinds of behaviour.

27、(同26题)As used in this passage, the word ’involuntary’ means____

A.normal.
B.abnormal.
C.particular.
D.automatic.

28、(同26题)Excitement, fear, and love are centered in____

A.the neocortex
B.The pituitary.
C.Brain 2.
D.The medulla.

29、(同26题)We can conclude from the passage that____

A.only humans have the neocotex section of the brain.
B.we know very little about the brain.
C.brain 3 is all we need to survive.
D.we still have a lot to learn about the brain.

30、(同26题)That passage suggests that____

A.man is the only animal that has emotions.
B.`mind control’ will be possible very soon.
C.research on the human brain is one of the most important types of research scientists are engaged in.

31、第三篇 Memory One day more than fifty years ago, a young man had an accident on his mo tor-bike in which he suffered a few apparently minor injuries. There was a bruise (肿) on the left side of his forehead and some slight bleeding from his left ear. He was taken to hospital for examination but X-rays did not reveal any other in juries. Nevertheless, the doctor who was treating him decided to keep him in ho spital for further observations because the young man was having difficulty in s peaking and seemed very confused. At the time of the accident, the young man was 22 years old, and the dat a was August, 1933. A week later, he was able to carry on what seemed a perfectly normal conversation. However, he told the doctor that he was only 11 years old and that the date was February, 1922. What is more, he could not remember anyth ing that had happened since 1922. For example, he could not recall having spent five years in Australia, or coming back to England and working for two years on a golf course. As time went by part of his memory of the eleven missing years come back . A few weeks later, he even remembered his years in Australia. But the two years of his life just before the accident were still a completely a blank. Three we eks after his injury, he went back to the village where he had been living for t hose two years. Everything seemed unfamiliar and he did not recall ever having b een there before. Despite this, he was able to take up his old job again in the village an d to do it satisfactorily. But he often got lost when walking around the village a nd found it difficult to remember what he had done during the day. Slowly, howev er, his memory continued to return so that, about ten weeks after the accident, he could even remember most of the previous two years. There remained only one complete gap in his memory: he could remember absolutely nothing about what he h ad done a few minutes immediately before the accident or the accident itself. T
