    Smart Exercise

    Doctors 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 have
    been 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 should
    A:be done in a group.
    B: be done on a daily basis.
    C: involve great difficulty.
    D:increase the heart rate.

    Sleep Lets Brain File Memories

    To 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?

    答案:A
    解析:
    To sleep.Perchance to file? 即当人体进入睡眠状态时,大脑对在白天形成的记忆进行组织和储存。
    第二段告诉我们,科学家分析了老鼠的脑电波,尤其是从somatosensory neocortex和hippocampus两个区域发出的脑电波。该段最后两句指出,这两个大脑区域的活动是互相作用的。第二段并没有说somatosensory neocortex或hippocampus起主导作用。
    第四段倒数第二句提供了答案。
    第四段最后一句中their brain scans,指上句中的subjects with the poorest memory recollection的大脑扫描,所以选择B项。
    锻炼身体和控制体重能保持葡萄糖水平,因此,去健身房就有了另外一个理由。

    _________61
    A:as
    B:of
    C:to
    D:at

    答案:C
    解析:
    前一句提到音乐训练可以提高沟通技巧和改善语言障碍,可见他们发现的应该是提升音乐技能与学习说话有着相同的(same)大脑活动过程。the same as…与……相同。unique独特的;different不同的;strange奇怪的。
    这项发现应该能够帮助在学习上有障碍的儿童。help帮助;tell告诉;remind提醒;entertain娱乐。
    这个句子的意思是:她说音乐训练与整合不同的信息相关,比如聆听音乐、看音符、触碰乐器,以及观察其他音乐演奏者等。shape塑造;relate关于;enhance加强,增强。只有 involve能够表示“涉及,与……相关”的意思。
    空格前一句讲的是音乐训练的过程,因此应该选择能表示过程的词汇,即D项。form 形式;step步骤;point观点;process过程。
    结合语境可知,本篇文章讲的是音乐训练与学习说话之间的关系,因此选择C项。play 玩耍;sing歌唱;speak说话;think思考。
    pass through是常用表达,意思是“经过,通过”的意思,用在空格处表明说话和音乐都通过脑干这个神经系统组织。没有use through这个短语。look through仔细查阅;put through 完成。
    由常识及语境可知,大脑控制着我们讲话的能力。develop发展,开发;control控制; assess评判;observe观察,遵守。
    空格前一句表明专家的观点,认为脑干不能被改善或改变;空格后一句表明Krauss及其团队的观点,即音乐训练可以改善脑干活动。两者是转折关系,故选择转折连词but。
    这个研究涉及的应该是具有不同音乐能力的个人。instrument乐器;ability能力;type 类型;contact接触。本篇文章并没有对乐器和音乐类型进行探讨。
    根据上文可知,音乐训练与学习说话涉及相同的大脑活动过程,由此可知这些电子设备观测的是大脑活动。physical体力的;musical音乐的;speech演讲,说话;brain大脑。
    similar to的意思是“与……相似”,是英语中的习惯表达。
    这个句子的意思是:人们接受音乐训练的时间越长,他们对音乐的声音和节奏就会越敏感。familiar熟悉的;inactive不活跃的;critical讽刺的,批判的;sensitive敏感的。
    这个句子的意思是:那些接受过音乐训练的人在感官测试中取得的进步也最大。re-duction减少;improvement改善,提升;interference干扰;implication蕴含。
    第一段最后一句提到,音乐训练能够帮助在学习上有障碍的儿童,因此选择B项。style 风格;disability残疾,无能;interest兴趣;approach方法,通道。
    空格前表示的是利用音乐改善听力,选项中表示听见的hear与听力相关。read阅读; write写;hear听见;change改变。

    Download Knowledge Directly to Your Brain

    For the first time,researchers have been able to hack into the process of learning in the biain,using
    induced brain patterns to create a learned behavior. 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.

    Which of the following statements is true of the experiment participants?
    A:They learned how to control MRL machines in the experiment.
    B:They were not told what to be learned in the experiment.
    C:They were paid to take part in the experiment.
    D:They were not cooperative in the experiment.

    答案:B
    解析:
    由文章第一段第一句中“researchers have been able to hack into the process of learning in the brain...”可知,研究人员已经能进人大脑的学习过程进行相关的了解,故应选A。
    由文章第三段的第二句话“They were examining...in which repetitive training improves a person ' s performance on a particular task.”可知,在对大脑视觉感学习能力的研究中,重复性的 训练改善了一个人做某种工作的表现,故选D。
    由文章第七段和第八段第一句中“The most surprising thing in this study is...without presenting the feature or subjects ' awareness of what was to be learned”可知,在实验过程中,实验 对象是不知道他们要学的内容的,其他各项文中均未提到,故选B。
    由文章第八段中“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”可知,这项研究不可思议的一点是,和某一特定视觉特征对应的神经激活 特征的归纳结果导致该视觉特征的功能的提升,也就是说,学习过程在这里和视觉功能联系在 了一起,故选B。
    由文章最后一段的内容可知,该研究可以让人获得新的知识、记忆,或者恢复由于事 故、疾病或者老龄化而损失的技能或知识,故选C。

    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?

    答案:A
    解析:
    由文章第一段内容可知,科学新发现进一步支持了一种理论,即当人体进人睡眠状态时,大脑对在白天形成的记忆进行组织和储存。"Tosleep.Perchancetofile?”由莎士比亚的名句“Tosleep:perchancetodream."(睡眠也许要做梦)转化而来,它在本句的意思是:睡觉也许要记忆整理,故选A。
    第二段提到科学家分析了老鼠的脑电波,尤其是从躯体感觉新皮层和海马体两个区域发出的脑电波。该段最后指出,这两个大脑区域的活动是相互作用的;第二段并未提及两者中的任何一个起主要作用。
    由文章第四段倒数第二句话“Subjectswiththepoorestmemoryrecollection,theteamdiscovered,alsodisplayedthepoorestglucosetolerance.”可知,D项正确。
    第四段最后一句“…theirbrainscans…中their指上句中的“Subjectswiththepoorestmemoryrecollection",所以B项正确?
    文章最后一段提到,锻炼身体和控制体重能够限制葡萄糖浓度,因而,去健身房就有了另外一个原因。第二篇本篇文章主要讲述了大量发展中国家的艾滋病患者由于没有得到治疗而死去的情况,接着指出应加强对艾滋病患者的救治,并提出了三种具体的救治办法。

    The author’s attitude towards “Diasporas” is that _____.
    A

    There is increasing hostility towards immigrants in rich countries.

    B

    Immigrant networks are a rare bright spark in the world economy and rich countries should welcome them.

    C

    The Diasporas should return to their homelands so that poor countries will not suffer as a result of “brain drain”.

    D

    Hard-working immigrants will depress the wages of the locals although they may greatly increase productivity.


    正确答案: B
    解析:
    文章多处提到移民为世界经济发展做出贡献。例如第六段提到在富裕国家的“Migrants”不仅“send cash to their families”;他们还会帮助公司“operate in their home country.”不仅如此,倒数第二段提到了移民为富裕国家也做出的贡献。最后一段也提到“Rich countries”将会从宽松的移民政策中获益。因此B项指出移民是世界经济中难得一见的亮点,富裕国家应该欢迎他们是符合作者对“diasporas”的态度的。A选项是一个事实,不是作者态度。因此不选A。文章最后一段“The prospect of working abroad spurs more people to acquire valuable skills, and not all subsequently emigrate”说明有些人只是到国外学习,并不移民;另外一些人才会回国开公司,因此担心不发达国家会“brain drain”是过分夸张的,故C选项错误。从文章第七段可以看出的确有一些研究表明来自“unskilled immigration”的竞争会压低“unskilled locals”的工资,但是其他研究发现,这种影响“to be small”或者“non-existent”,因此D项错误。

    In what sense does foreign language teaching methodology help you in your professional development?

    正确答案: A foreign language teacher has to not only make his students understand the language, namely the pronunciation, vocabulary, grammar, etc., he must also develop their communicative competence so that they can use the language they have learned correctly, appropriately and expressively in real situations. In order to do well this complicated job, the teacher needs to know, apart from a comprehensive knowledge of the language and the ability to use it, as many teaching methods and techniques as possible, and understand the underlying theories and principles, therefore he not only knows what to teach and how to do it, but also why he should do it in a certain way and how to solve problems when they arise. In this way he will have full confidence in doing his job well.
    Foreign language teachers understand that knowing a language does not necessarily mean that you can teach the language well. Teaching is an art as well as a science. If you do not know the theories, principles, methods or techniques of teaching, you might be able to teach a foreign language based on your experience, but you cannot hope to achieve good results, nor can you give your or your colleagues’ teaching a rational evaluation or a critical appraisal. There are surely limitations in teaching by drawing only on experience, though experience is important. The theory you learnt from the methodology course can guide, support and conceptualize practice. New insights you get by sharing ideas of other people will bring you great benefit. As the old saying goes: “Travel broadens the mind”. In the same way learning Foreign Language Teaching Methodology will surely broaden the mind of teachers.

    Brain Drain

    1.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.

    People living abroad help foreigners to know about______.
    A:its harmful effects
    B:immigrated people
    C:the local government
    D:their cultures and traditions
    E:the hardworking engineers
    F: in quality and quantity

    答案:D

    A.where
    B.when
    C.that
    D.why

    答案:D
    解析:
    动词搭配+从句辨析本句句义为“我们会突然想不起来放钥匙_____”。划线处及之后的“_____we put the key just a moment ago”作remember的宾语从句。根据put的用法“put something in some place”(把某物放在某处)可知,空格处缺少的是地点状语,在四个选项中只有where表示地点状语,因此正确答案是D。why和when分别引导原因状语从句和时间状语从句,可放到空格处,但是无法做put的地点状语,所以排除选项A和B。that放在动词remember之后引导宾语从句,此时的that没有任何实际意义可以省略,而且that并不能充当put的地点状语,所以排除选项C。

    Smart Exercise

    Doctors 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 have
    been 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.

    The expression"beef up"in paragraph 3 means
    A:control.

    For the first time,researchers have been able to hack into the process of learning in the biain,using
    induced brain patterns to create a learned behavior. 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.

    答案:C
    解析:
    由文章第一段第一句中“researchers have been able to hack into the process of learning in the brain...”可知,研究人员已经能进人大脑的学习过程进行相关的了解,故应选A。
    由文章第三段的第二句话“They were examining...in which repetitive training improves a person ' s performance on a particular task.”可知,在对大脑视觉感学习能力的研究中,重复性的 训练改善了一个人做某种工作的表现,故选D。
    由文章第七段和第八段第一句中“The most surprising thing in this study is...without presenting the feature or subjects ' awareness of what was to be learned”可知,在实验过程中,实验 对象是不知道他们要学的内容的,其他各项文中均未提到,故选B。
    由文章第八段中“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”可知,这项研究不可思议的一点是,和某一特定视觉特征对应的神经激活 特征的归纳结果导致该视觉特征的功能的提升,也就是说,学习过程在这里和视觉功能联系在 了一起,故选B。
    由文章最后一段的内容可知,该研究可以让人获得新的知识、记忆,或者恢复由于事 故、疾病或者老龄化而损失的技能或知识,故选C。

    induced brain patterns to create a learned behavior. 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.

    What have researchers been able to do with the help of the study?
    A:Discover a person's learning process in the brain.
    B:Make a person know how to do something without learning.
    C:Set up different learning patterns for different people.
    D:Enable people to learn Kung fu instantly.

    答案:A
    解析:
    由文章第一段第一句中“researchers have been able to hack into the process of learning in the brain...”可知,研究人员已经能进人大脑的学习过程进行相关的了解,故应选A。
    由文章第三段的第二句话“They were examining...in which repetitive training improves a person ' s performance on a particular task.”可知,在对大脑视觉感学习能力的研究中,重复性的 训练改善了一个人做某种工作的表现,故选D。
    由文章第七段和第八段第一句中“The most surprising thing in this study is...without presenting the feature or subjects ' awareness of what was to be learned”可知,在实验过程中,实验 对象是不知道他们要学的内容的,其他各项文中均未提到,故选B。
    由文章第八段中“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”可知,这项研究不可思议的一点是,和某一特定视觉特征对应的神经激活 特征的归纳结果导致该视觉特征的功能的提升,也就是说,学习过程在这里和视觉功能联系在 了一起,故选B。
    由文章最后一段的内容可知,该研究可以让人获得新的知识、记忆,或者恢复由于事 故、疾病或者老龄化而损失的技能或知识,故选C。

    In what sense does foreign language teaching methodology help you in your professional development?
    A foreign language teacher has to not only make his students understand the language, namely the pronunciation, vocabulary, grammar, etc., he must also develop their communicative competence so that they can use the language they have learned correctly, appropriately and expressively in real situations. In order to do well this complicated job, the teacher needs to know, apart from a comprehensive knowledge of the language and the ability to use it, as many teaching methods and techniques as possible, and understand the underlying theories and principles, therefore he not only knows what to teach and how to do it, but also why he should do it in a certain way and how to solve problems when they arise. In this way he will have full confidence in doing his job well.
    Foreign language teachers understand that knowing a language does not necessarily mean that you can teach the language well. Teaching is an art as well as a science. If you do not know the theories, principles, methods or techniques of teaching, you might be able to teach a foreign language based on your experience, but you cannot hope to achieve good results, nor can you give your or your colleagues’ teaching a rational evaluation or a critical appraisal. There are surely limitations in teaching by drawing only on experience, though experience is important. The theory you learnt from the methodology course can guide, support and conceptualize practice. New insights you get by sharing ideas of other people will bring you great benefit. As the old saying goes: “Travel broadens the mind”. In the same way learning Foreign Language Teaching Methodology will surely broaden the mind of teachers.

    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.
