解析：
录音中提到“This brain drain will accelerate as the global economy expands.”(随着全球经济的扩张，这种人才流失将会加快)，This brain drain指的是“人才流失”，结合前文中讲的内容也即是专业人才移向富裕国家，所以选C。
【录音原文】
New information and communication technologies are driving the global economy. They have brought down the cost of global communication, and innovative tools have become easier to use. The Internet, mobile phones and electronic funds transfer are opening up the global marketplace. The Internet had more than 140 million users in the middle of 1998, but 93% of users were in the richest 20% of nations.
Improved communication can foster great advances in health care and education. It also breaks down barriers of size, time, and distance. With the Internet, consumers can purchase products from any country in the world, and any innovative producers can easily reach a much larger market place and take advantage of economies of scale.
Improvements in technology also bring up the issue of intellectual property rights. Tighter property rights are increasing the price of technology transfer, blocking many developing countries from their use, whether it is in production, communication, education or health care, this in turn increases the power and wealth of those who largely own the property fights.
What is more, new information and communication technologies have also promoted the international movement of labor. This movement has been growing since the 1960’s. Now about 2.3% of the world population lives outside their country of birth and 1.5% of the world’s workforce works in countries other than those of its citizenship. This trend is on the increase with the World Wide Web opening the door for skilled individuals to apply for positions in almost any country in the world. In developing countries, students are studying subjects that will give them a passage from their current existence to one of expected wealth in a rich nation. This brain drain will accelerate as the global economy expands.

Brain Drain1.Brain drain is a phenomenon under which"people of a nation move to another nation due to financial benefits and also due to economical reasons,but there are many more reasons behind it". If we think deeply to the topic,we would find that this phenomenon has more disadvantages than advantages.2.This phenomenon has many advantages for receiving countries which will automatically benefit from the skills and talents of immigrated people who were educated and qualified in their home countnes.3.However,developing countries are deeply affected by this phenomenon since they are deprived from millions of their skilled workers, doctors,hardworking Engineers,and billions of man power. Those elites represent the backbone of their economies and once they travel abroad,their economies will not flourish and promote.In fact,there are many reasons behind brain drain.Firstly,the Government is the first responsible for brain drain. The salaries paid by local companies are much less than multinational foreign companies,which pushes millions of intelligent,hardworking Engineers to leave their native countries to look for a better life and opportunities.Secondly,the status and facilities provided by foreign companies are much higher in quality and quantity.Also,some people find it a matter of pride and dignity to work as an employee in foreign countries.4.But we have to mention that brain drain does not only affect developing countries but also has some advantages for them.People living abroad help foreigners to know about their cultures and traditions.Also,they give information about various natural beauties and tourist spots in their home countries,which encourages tourists to visit them. This in turn increases tourist income.Brain drain also helps in increasing their foreign exchanges.5.But at last you would find that brain drain has more disadvantages than advantages on developing or poor countries.So,to stop brain drain,local governments should make people aware of its harmful effects.Also Government should provide opportunities to their elites and should provide them with handsome salary so that they can serve their own mother nation.Paragraph 3______A:Harmful effects of brain drain on developing countries.B:Brain drain in developing countries.C:Strategies governments can use to curb brain drain.D:Good effects of brain drain on receiving countries.E:Brain drain and elites.F: Benefits brain drain brings to developing countries.

第三篇 Smart ExerciseDoctors are starting to find more and more information that suggests a connection between exercise and brain development.Judy Cameron,a scientist at Oregon Health and Science University,studies brain development.According to her research,it seems that exercise can make blood vessels,including those in the brain,stronger and more fully developed.Dr. Cameron claims this allows people who exercise to concentrate better. As she says:"While we already know that exercise is good for the heart,exercise can literally cause physical changes in the brain."The effects of exercise on brain development can even be seen in babies.Babies who do activities that require a lot of movement and physical activity show greater brain development than babies who are less physically active.With babies,even a{ittle movement can show big results. Margaret Barnes , a pediatrician（儿科医师）,believes in the importance of exercise.She thinks that many learning disabilities that children have in elementary school or high school can be traced back to a lack of movement as babies. "Babies need movement that stimulates their five senses.They need to establish a connection between motion and memory.In this way,as they get older,children will begin to associate physical activity with higher learning,"says Margaret. Older people can beef up their brains as well.Cornell University studied a group of seniors ranging in age from seventy to seventy-nine. Their study showed a short-term memory increase of up to 40 percent after exercising just three hours a week.The exercise does not have to be very difficult,but it does have to increase the heart rate.Also,just like the motion for infants,exercise for older people should involve some complexity.Learning some new skills or motions helps to open up memory paths in the brain that may not havebeen used for a long time.For most people,any type of physical activity that increases the heart rate is helpful. The main goal is to increase the brain's flow of blood.And your brain can benefit from as little as two to three hours of exercise a week. To be beneficial,exercise for older people shouldA:be done in a group. B: be done on a daily basis.C: involve great difficulty. D:increase the heart rate.

第二篇Sleep Lets Brain File MemoriesTo sleep.Perchance to file?Findings published online this week by the proceedings of the National Academy of Sciences further support the theory that the brain organizes and stows memories formed during the day while the rest of the body is catching zzz's.Gyorgy Buzsaki of Rutgers University and his colleagues analyzed the brain waves of sleeping rats and mice. Specifically,they examined the electrical activity emanating（散发）from the somatosensory（耳、目、口等以外的）neocortex（新大脑皮层）(an area that processes sensory information) and the hippocampus（海马）,which is a center for learning and memory. The scientists found that oscillations in brain waves from the two regions appear to be intertwined.So-called sleep spindles (bursts of activity from the neocortex)were followed tens of milliseconds later by beats in the hippocampus known as ripples.The team posits that this interplay between the two brain regions is a key step in memory consolidation.A second study,also published online this week by the proceedings of the National Academy of Sciences,links age-associated memory decline to high glucose levels.Previous research had shown that individuals with diabetes（糖尿病，多尿症）suffer from increased memory problems.In the new work,Antonio Convit of New York University School of Medicine and his collaborators studied 30 people whose average age was 69 to investigate whether sugar levels,which tend to increase with age,affect memory in healthy people as well.The scientists administered recall tests, brain scans（细看，审视，浏览，扫描）and glucose tolerance tests, which measure how quickly sugar is absorbed from the blood by the body's tissues.Subjects with the poorest memory recollection,the team discovered,also displayed the poorest glucose tolerance.In addition,their brain scans showed more hippocampus shrinkage than those of subjects better able to absorb blood sugar." Our study suggests that this impairment（损害、损伤）may contribute to the memory deficits （赤字、不足额）that occur as people age."Convit says."And it raises the intriguing possibility that improving glucose tolerance could reverse some age-associated problems in cognition."Exercise and weight control can help keep glucose levels in check（阻止、制止）,so there may be one more reason to go to the gym.Which of the following statements is nearest in meaning to the sentence"To sleep.Perchance to file?"A:Does brain arrange memories in useful order during sleep?B:Does brain have memories when one is sleeping?C:Does brain remember files after one falls asleep?D:Does brain work on files in sleep?

It's not quite as advanced as an instant Kung-fu down- load,and it's not as sleek as cognitive inception,but it's still an important finding that could lead to new teaching and rehabilitation techniques.Future therapies could decode the brain activity patterns of an athlete or a musician,and use them as a benchmark for teaching another person a new activity,according to the researchers.Scientists from Boston University and ATR Computational Neuroscience Laboratories in Kyoto used functional magnetic resonance imaging,or fMRI,to study the learning process.They were examining the adult brain's aptitude for visual perceptual learning,or VPL,in which repetitive training improves a per- son's performance on a particular task.Whether adults can do this as well as young people has been an on- going debate in neuroscience.Led by BU neuroscientist Takeo Watanabe,researchers used a method called decoded fMRI neurofeed- back to stimulate the visual cortex.First they showed participants circles at different orientations.Then they used fMRI to watch the participants'brain activity.The researchers were then able to train the participants to recreate this visual cortex activity.The volunteers were again placed in MRI machines and asked to visualize shapes of certain colors.The participants were asked to"somehow regulate activity in the posterior part of the brain"to make a solid green disc as large as they could.They were told they would get a paid bonus proportional to the size of this disc, but they weren't told anything about what the disc meant.The researchers watched the participants'brain activity and monitored the activation patterns in their visual cortices."Participants can be trained to control the overall mean activation of an entire brain region,"the study authors write,"or the adtivation in one region relative to that in another region."This worked even when test subjects were not aware of what they were learning,the researchers said."The most surprising thing in this study is that mere inductions of neural activation patterns corresponding to a specific visual feature led to visual performance improvement on the visual feature,without presenting the fea- ture or subjects' awareness of what was to be learned,"Watanabe said in a statement.Watanabe and colleagues said this method can be a powerful tool."It can'incept' a person to acquire new learning, skills,or memory,or possibly to restore skills or knowledge that has been damaged through accident,disease,or aging,without a person's awareness of what is learned or memorized,"they write.Who are most likely to benefit from the study?A:Teenagers.B:Musicians.C:Senior people.D:Athletes.

Sleep Lets Brain File MemoriesTo sleep.Perchance to file?Findings published online this week by the Proceedings of the National Academy of Science further support the theory that brain organizes and stows memories formed during the day while the rest of the body is catching zzz's.Gyorgy Buzsaki of Rutgers University and his colleagues analyzed the brain waves of sleeping rats and mice.Specifically,they examined the electrical activity emanating from the somatosensory neocortex(an area that processes sensory information)and the hippocampus,which is a center for learning and memory.The scientists found that oscillations in brain waves from the two regions appear to be intertwined.So-called sleep spindles(bursts of activity from the neocortex)were followed tens of milliseconds later by beats in the hippocampus known as ripples.The team posits that this interplay between the two brain regions is a key step in memory consolidation.A second study,also published online this week by the Proceedings of the National Academy of Sciences,links age-associated memory decline to high glucose level.Previous research had shown that individuals with diabetes suffer from increased memory problems.In the new work,Antonio Convit of New York University School of Medicine and his collaborators studied 30 people whose average age was 69 to investigate whether sugar levels,which tend to increase with age,affect memory in healthy people as well.The scientists administered recall tests,brain scans and glucose tolerance tests,which measure how quickly sugar is absorbed from the blood by the body's issues.Subjects with the poorest memory recollection,the team discovered,also displayed the poorest glucose tolerance.In addition, their brain scans showed more hippocampus shrinkage than those of subjects better able to absorb blood sugar."Our study suggests that this impairment may contribute to the memory deficits that occur as people age,"Convit says."And it raises the intriguing possibility that improving glucose tolerance could reverse some age一associated problems in cognition?”Exercise and weights control can help keep glucose level in check,so there may be one more reason to go to the gym.Which of the following statements is the nearest in meaning to the sentence"To sleep.Perchance to file?"A:Does brain arrange memories in useful order during sleep?B:Does brain have memories when one is sleeping?C:Does brain remember files after one falls asleep?D:Does brain work on files in sleep?
