The brain drain (人才流失) is a universal phenomenon, and countries that don't face up to

The brain drain (人才流失) is a universal phenomenon, and countries that don't face up to the new reality will be losing some of their most precious resources. The northeast of England is its poorest region, and has experienced a severe loss of highly qualified professionals-to-be. Some of the most able 18-year-olds are going to other parts of Britain, even to other countries. What is happening here is happening to Britain as a whole. Most noticeably, there is a growing trend of British students' taking degrees in American universities. This year the number will break the psychological barrier of 1 000 students for the first time.

And what is happening at the secondary-school level is happening to higher education. Wherever they come from, today's students have a very different perspective on education from their parents. Because of television, the Internet and their own travels, these students see the world as a much smaller place than their parents once did. They are more confident in accepting the challenge of moving from one country to another, from one culture to another; in many eases they can even apply to schools over the Internet. Students are also more aware of the overall cost of education and are looking for value for money. Plus, for many, education linked to travel is a better option than education at home.

In the context of student globe-trotters (周游世界者), as world-class British universities like Oxford suddenly find themselves fighting over British students with the Harvards of the world, they face major challenges. It is not simply that Harvard is a wealthier institution: Harvard University's endowment— $14.5 billion—is estimated to be ten times that of Oxford. Harvard also offers a radically different educational experience, stressing breadth of study and real-world applications of knowledge.

Today, bound in by nearly a millennium of tradition and lacking sufficient financial help from the national government, Oxford cannot easily respond to the quickened global pace of educational change. Rightly or wrongly, Oxford in particular has been slow—or unwilling—to put the kind of emphasis other universities have on more business-friendly curricula (课程). Thus it has slipped behind universities like Cambridge and Harvard in the battle for resources that tend to go to more business-minded institutions.

Education is an expensive business, but the consequences of a failure to educate—especially in an increasingly globalized world—are even more expensive.

From the first paragraph, we know that ______ .

A.many countries are experiencing the brain drain, Britain is one of them

B.most British students prefer to take degrees in American universities than in British ones

C.Britain is suffering a more serious loss of professionals-to-be than other countries

D.the brain drain is only happening in the northeast poor regions of England

What Is Death? People in the past did not question the difference between life and de

What Is Death?

People in the past did not question the difference between life and death. They could see that a person died when his heart stopped beating. People have learned, however, that the body does not die immediately when the heart stops beating. They discovered that we remain alive as long as our brain remains active. Today the difference between life and death is not as easy to see as in the past. Modern medical devices can keep the heart beating and the lungs breathing long after the brain stops. But is this life?

This question has caused much debate among citizens in the United States. Many of them want a law that says a person is dead when the brain dies. A person should be considered dead when brain waves stop even if machines can keep the body alive. Such a law would permit doctors to speed removal (切除) of undiseased (没病的) organs for transplant (移植) operations.

The brain is made of thousands of millions of nerve cells. These cells send and receive millions of chemical and electrical messages every day. In this way the brain controls the other body activities. Nerve-cell experts say it is usually easy to tell when the brain has died. They put small electrodes (电极) on a person's skull (头骨) to measure the electrical signals that pass in and out of the brain. These brain waves are recorded on a television screen or on paper. The waves move up and down every time the brain receives messages from the nerve cells. The brain is dead when the waves stop moving.

Although there are people who oppose the idea of a law on brain block for various reasons, the idea of brain wave activity as a test of death is slowly being accepted.

第二节 完型填空

阅读下面短文,从短文后所给各题的四个选项(A、B、C和D)中选出能填入相应空白处的最佳选项。

During the 9th century scientists found that when certain parts of the brain of a man were 【B1】 ,he would lose the 【B2】 to do certain things. And so, people thought that each part of the brain does a different 【B3】 . But modern research has 【B4】 out that this is not so, for it is not 【B5】 to say 【B6】 what each part of the brain does.

In the past fifty years there 【B7】 a great increase in the amount of research 【B8】 on the brain. Chemists and biologists have 【B9】 that the 【B10】 the brain works it is not so 【B11】 as people in general may think. Chemists tell us that 100,000 chemical changes 【B12】 in the brain every second. Some recent researches also 【B13】 that we can remember every thing 【B14】 happens 【B15】 us. We 【B16】 not be able to recall(回忆)the things we've heard and seen, but it is all kept there in the storehouse of the human mind.

Earlier scientists thought the power of one's brain got weaker as one grow 【B17】 . But it is now thought that is not 【B18】 . As long as the brain is 【B19】 【B20】 exercise it keeps its ability. It has been proved that an old person who has always been active in the mind has a quicker mind than a young person who has only done physical work without using much of his brain. It is now thought that the more work we give our brains, the more work they are able to do.

【B1】

A.destroyed

B.injured

C.broken

D.wounded

根据材料请回答 36~40 题

Sleep

Sleep is part of your daily activity cycle, but there are several differenttypes or stages of sleep and they too occur in cycles.If you are an average sleeper, your sleep cycle will go something like this: When you first drift off into sleep your eyes will roll about a bit, your temperature will drop slightly, your muscles will relax, and your breathing will slow and become quite regular.Your brain waves slow down a bit too.This is called Stage 1 sleep.

For the next half hour or so, as you relax more and more, you will drift down through Stage 2 and Stage 3 sleep.The lower your stage of sleep, the slower your brain waves will be.Then, about 40-60 minutes after you lose consciousness, you will have reached the deepest sleep of all.Your brain waves will show the delta rhythm.This is Stage 4 sleep.

You may think that you stay at this deep fourth stage all the rest of the night, but that turns out not to be the case.Instead, about 80 minutes after you fall into sleep your activity cycle wilt increase slightly.The delta rhythm will disappear, to be replaced by the activity pattern of brain waves.Your eyes will begin to move around under your closed eyelids as if you were looking at something occurring in front of you.This period of Rapid Eye Movements lasts for some 8-15 minutes and is called REM sleep.During both light and deep sleep, the muscles in your body are relaxed but capable of movement.However, as you slip into REM sleep, a very odd thing occurs.Most of the voluntary muscles(随意肌)in your body become paralyzed(麻痹).Although your brain shows very rapid bursts of neural activity during REM sleep, your body is incapable of moving.

第 36 题 The lower the stage of sleep

A.the greater the alpha waves will be

B.the slower the brain waves will appear

C.the slower the activity pattern of the brain

D.the deeper the sleeper gets to unconsciousness

In recent years American society has become increasingly dependent on its universities to
find solutions to its major problems. It is the universities that have been charged with the principal responsibility for developing the expertise to place men on the moon; for dealing with our urban problems and with our deteriorating environment; for developing the means to feed the world's rapidly increasing population. The effort involved in meeting these demands presents its own problems. In addition, this concentration on the creation of new knowledge significantly impinges on the universities' efforts to perform. their other principal functions, the transmission and interpretation of knowledge the imparting of the heritage of the past and the preparing of the next generation to carry it forward.

With regard to this, perhaps their most traditionally sanctioned task, colleges and universities today find themselves in a serious hind generally. On the one hand, there is the American commitment, entered into especially since WWII, to provide higher education for all young people who can profit from it. The result of the commitment has been a dramatic rise in enrollments in our universities, coupled with a radical shift from the private to the public sector of higher education. On the other hand, there are serious and continuing limitations on the resources available for higher education.

While higher education has become a great "growth industry", it is also simultaneously a tremendous drain on the resources of nation. With the vast increase in enrollment and the shift in priorities away from education in state and federal budgets, there is in most of our public institutions a significant decrease in per capita outlay for their students, one crucial aspect of this drain on resources lies in the persistent shortage of trained faculty, which has led, in rum, to a declining standard of competence in instruction.

Intensifying these difficulties is, as indicated above, the concern with research, with its competing claims on resources and the attention of the faculty. In addition, there is a strong tendency for the institutions; organization and functioning to conform. to the demands of research rather than those of teaching.

According to the passage,—is the most important function of institutions of higher education.

A.creating new knowledge

B.providing solutions to social problems

C.making experts on sophisticated industries out of their students

D.preparing their students to transmit inherited knowledge

In the 1950s, the pioneers of artificial intelligence (AI) predicted that, by the end of this century, computers would be conversing with us at work and robots would be performing our housework. But as useful as computers are, they're nowhere close to achieving anything remotely resembling these early aspirations for humanlike behavior. Never mind something as complex as conversation: the most powerful computers struggle to reliably recognize the shape of an object, the most elementary of tasks for a ten-month-old kid.

A growing group of AI researchers think they know where the field went wrong. The problem, the scientists say, is that AI has been trying to separate the highest, most abstract levels of thought, like language and mathematics, and to duplicate them with logical, step-by-step programs. A new movement in AI, on the other hand, takes a closer look at the more roundabout way in which nature came up with intelligence. Many of these researchers study evolution and natural adaptation instead of formal logic and conventional computer programs. Rather than digital computers and transistors, some want to work with brain cells and proteins. The results of these early efforts are as promising as they are peculiar, and the new nature-based AI movement is slowly but surely moving to the forefront of the field.

Imitating the brain's neural network is a huge step in the right direction, says computer scientist and biophysicist Michael Conrad, but it still misses an important aspect of natural intelligence. "People tend to treat the brain as if it were made up of color-coded transistors", he explains, "but it's not simply a clever network of switches. There are lots of important things going on inside the brain cells themselves. " Specifically, Conrad believes that many of the brain's capabilities stem from the pattern recognition proficiency of the individual molecules that make up each brain cell. The best way to build an artificially intelligent device, he claims, would be to build it around the same sort of molecular skills.

Right now, the option that conventional computers and software are fundamentally incapable of matching the processes that take place in the brain remains controversial. But if it proves true, then the efforts of Conrad and his fellow AI rebels could turn out to be the only game in town.

The author says that the powerful computers of today ______.

A.are capable of reliably recognizing the shape of an object

B.are close to exhibiting humanlike behavior

C.are not very different in their performance from those of the 50's

D.still cannot communicate with people in a human language
