(A)第十一篇：Bill Gates: Unleashing Your Creativity

I've always been an optimist and I suppose it is rooted in my belief that the power of creativity and intelligence can make the word a better place. For as long as I can remember, I've loved learning new things and solving problems. So when I sat down at a computer for the first time in seventh grade, I was hooked. It was a clunky old teletype machine and it could barely do anything compared to the computers we have today. But it changed my life.

When my friend Paul Allen and I started Microsoft 30 years ago, we had a vision of \

computer on every desk and in every home\which probably sounded a little too optimistic at a time when most computers were the size of refrigerators. But we believed that personal computers would change the world. And they have.

And after 30 years, I'm still as inspired by computers as I was back in seventh grade.

I believe that computers are the most incredible tool we can use to feed our curiosity and

inventiveness -- to help us solve problems that even the smartest people couldn't solve on their own.

Computers have transformed how we learn, giving kids everywhere a window into all of the world's knowledge. They're helping us build communities around the things we care about and to stay close to the people who are important to us, no matter where they are.

Like my friend Warren Buffett, I feel particularly lucky to do something every day that I love to do. He calls it \at Microsoft is as challenging as ever, but what makes me \to work\recognize your handwriting or your speech, or one that can store a lifetime's worth of photos, and they say, \didn't know you could do that with a PC5 !\

But for all the cool things that a person can do with a PC, there are lots of other ways we can put our creativity and intelligence to work to improve our world6. There are still far too many

people in the world whose most basic needs go unmet7. Every year, for example, millions of

people die from diseases that are easy to prevent or treat in the developed world.

I believe that my own good fortune brings with it a responsibility to give back to the world.

My wife, Melinda, and I have committed to improving health and education in a way that can help as many people as possible.

As a father, I believe that the death of a child in Africa is no less poignant or tragic than9 the death of a child anywhere else, and that it doesn't take much to make an immense difference in these children's lives. I'm still very much an optimist, and I believe that progress on even the world's toughest

problems is possible -- and it's happening every day. We're seeing new drugs for deadly diseases,

new diagnostic tools, and new attention paid to the health problems in the developing world.

I'm excited by the possibilities I see for medicine, for education and, of course, for

technology. And I believe that through our natural inventiveness, creativity and willingness to solve tough problems, we're going to make some amazing achievements in all these areas in my lifetime. 注释：

(A)第十四篇：Stage Fright

Fall down as you come onstage. That's an odd trick. Not recommended. But it saved the pianist Vladimir Feltsman when he was a teenager back in Moscow. The veteran cellist Mstislav

Rostropovich tripped him purposely to cure him of pre-performance panic,Mr. Feltsman said, \

my fright was gone. I already fell. What else could happen?\

Today, music schools are addressing the problem of anxiety in classes that deal with

performance techniques and career preparation. There are a variety of strategies that musicians can learn to fight stage fright and its symptoms:icy fingers, shaky limbs ,racing heart,blank mind.

Teachers and psychologists offer wide-ranging advice, from basics like learning pieces inside out, to mental discipline, such as visualizing a performance and taking steps to relax. Don't deny that you're jittery ,they urge; some excitement is natural, even necessary for dynamic playing. And play in public often, simply for the experience.

Psychotherapist Diane Nichols suggests' some strategies for the moments before performance, \two deep abdominal breaths, open up your shoulders, then smile,\she says. \not one of these 'please don't kill me' smiles. Then choose three friendly faces in the audience, people you would communicate with and make music to, and make eye contact with them. \Extreme demands by mentors or parents are often at the root of stage fright, says Dorothy

Delay, a well-known violin teacher. She tells other teachers to demand only what their students are able to achieve. .

When Lynn Harrell was 20, he became the principal cellist of the Cleverland Orchestra, and he suffered extreme stage fright. \I got so nervous I was sure the audience could see my chest responding to the throbbing. It was just total panic. I came to a point where I thought, ' If I have to go through this to play music, I think I' m going to look for another job. Recovery, he said, involved developing humility-recognizing that whatever his talent, he was fallible, and that an imperfect concert was not a disaster. 6

It is not only young artists who suffer, of course. The legendary pianist Vladimir Horowitz's

nerves were famous. The great tenor Franco Corelli is another example. \Actually, success can make things worse. \the beginning of your career,when you're scared to death, nobody knows who you are, and they

don't have any expectations,\to lose. Later on, when you're known, p.eople are coming to see you, and they have certain expectations. You have a lot to lose. \

Anderson added, \never stop being nervous until I've sung my last note. \注释：

1.Stage Fright：怯场

2.The veteran cellist Mstislav Rostropovich tripped him purposely to cure him of pre—performance panic.资深大提琴家Mstislav Rostropovich故意把Vladimir Feltsman绊倒，

因而治愈了他的上台前的恐惧症。cure somebody of something(illness，problem)：医治好病(解决问题)。

3.?its symptoms：icy fingers，shaky limbs，racing heart，blank mind：怯场的症状有：手指冰凉、四肢发抖、心跳加速、大脑一片空白。

4.Teachers and psychologists offer wide? ranging advice，from basics like learning pieces inside out?：老师和心理学家提出了方方面面的建议，从基础的做法，比如，将演奏曲目烂熟于

心??inside out：in great detail(详细的，从里到外的)

5.I came to a point where I thought，‘If I have to go through this to play music，I think l’m goingto look for anotherjob.’我曾经一度认为，如果演出要经历这种慌乱，我宁可另找一份工作。

6.Recovery，he said，involved developing humility——recognizing that whatever his talent，he wasfallible，and that an imperfect concert was not a disaster.要克服怯场，就要学会谦虚，即认识到 不论自己有多大的才能，都可能犯错误;一场音乐会即使有不完美的地方，也不是要命的事情。 练习：

(适度的兴奋对于精彩演出是正常甚至是必要的)

5.c第四段提到克服怯场的方法之一是：在观众中选择三名比较友善的人，与他们做眼神交流。所以克服怯场要靠自己而不是指望所有的观众都友好。 6.A第五段讲了怯场的根源在于导师或父母对表演者要求太高。Extreme demands就是expect too much of them的意思。

7.B第七段讲的是：不只年轻艺术家会怯场，钢琴家Vladimir Horowitz和男高音Franco Corelli亦不能幸免。Never一词不恰当。

(B)第8篇 What Is a Dream?

For centuries, people have wondered about the strange things that they dream about. Some

psychologists say that this nighttime activity of the mind has no special meaning. Others, however, think that dreams are an important part of our lives. In fact, many experts believe that dreams can tell us about a person's mind and emotions.

Before modem times, many people thought that dreams contained messages from God. It was only in the twentieth century that people started to study dreams in a scientific way.

The Austrian psychologist, Sigmund Freud, was probably the first person to study dreams

scientifically. In his famous book, The interpretation of Dreams ( 1900 ), Freud wrote that dreams

are an expressions of a person's wishes. He believed that dreams allow people to express the

feelings, thoughts, and fears that they are afraid to express in real life. The Swiss psychiatrist Carl Jung was once a student of Freud' s. Jung, however, had a different idea about dreams. Jung believed that the purpose of a dream was to communicate a message to the dreamer. He thought people could learn more about themselves by thinking about their dreams. For example, people who dream about falling may learn that they have too high an opinion of themselves. On the other hand, people who dream about being heroes may learn that they think too little of themselves.

Modem-day psychologists continue to develop theories about dreams. For example,

psychologist William Domhoff from the University of California, Santa Cruz, believes that dreams

are tightly linked to a person's daily life, thoughts, and behavior. A criminal, for example, might dream about crime.

Dornhoff believes that there is a connection between dreams and age. His research shows that children do not dream as much as adults. According

to Domhoff, dreaming is a mental skill that needs time to develop. He has also found a link between dreams and gender. His studies show that the dreams of men and women are different. For example, the people in men's dreams are often other men, and the dreams often involve fighting. This is not true of women's dreams. 3 Domhoff found this gender difference in the dreams of people from 11 cultures around the world, including both modem and traditional ones.

Can dreams help us understand ourselves? Psychologists continue to try to answer this question in different ways. However, one thing they agree on this: If you dream that something terrible is going to occur,you shouldn't panic. The dream may have meaning, but it does not mean that some terrible event will actually take place. It's important to remember that the world of dreams is not the real world. 注释：

1.A这句话恰好表达了本文第一段的意思。即有些心理学家认为，人脑睡眠中的活动没有特别意义;而有些人则认为，梦可以揭示人的思维和情感。.

2.A第三段的最后一句讲的是弗洛伊德认为梦反映了人们在现实情况下害怕表达的情感、想法或恐惧。此句与本叙述一致。

3.B第四段的第二句和第三句：Jung believed that the purpose of a dream was to communicate a message to the dreamer.(荣格认为梦的用途是向做梦者传递一个信息)He thought people could learn more about themselves by thinking about their dreams.(他认为人们通过思考所做的梦能够更好地了解自己)。他给出了两个例子来说明他的论点。 4.C文中没有提及。

5.A依据第六段，Domhoff研究得出：婴儿不像成人做那么多的梦，做梦是一种需要时间提高的技能。这就说明了婴儿不具备成人做梦的能力。

6.A本文第七段讲述了做梦与性别的关系。第二句更指出男人和女人做的梦是不同的。

7.B最后一段的倒数第二句讲的是：梦可能会有意义，但并不表示一些恐怖事情就一定会发生。因而不能预测未来。

(B)第十篇：The Biology of Music

Humans use music as a powerful way to communicate. It may also play an important role in

love. But what is music, and how does it work its magic? Science does not yet have all the

answers.

What are two things that make humans different from animals? One is language, and the other is music. It is true that some animals can sing ( and many birds sing .better than a lot of people). However,the songs of animals, such as birds and whales, are very limited. It is also true that humans, not animals ,have developed musical instruments.

Music is strange stuff. It is clearly different from language. However, people can use music to communicate things -- especially their emotions. When music is combined with speech in a song, it is a very powerful form of communication. But, biologically speaking, what is music?

If music is truly different from speech, then we should process music and language in different parts of the brain. The scientific evidence suggests that this is true.

Sometimes people who suffer brain damage lose their ability to process language. However, they don't automatically lose their musical abilities. For example, Vissarion Shebalin, a Russian

composer, had a stroke in 1953. It injured the left side of his brain. He could no longer speak or

understand speech. He could, however, still compose music until his death ten years later. On the

other hand, sometimes strokes cause people to lose their musical ability, but they can still speak and understand speech. This shows that the brain processes music and language separately.

By studying the physical effects of music on the body, scientists have also learned a lot about how music influences the emotions. But why does music have such a strong effect on us? That is a harder question to answer. Geoffrey Miller, a researcher at University College, London, thinks that music and love have a strong connection. Music requires special talent, practice, and physical ability. That's why it may be a way of showing your fitness to be someone's.mate. For example, singing in tune or playing a musical instrument requires fine muscular control. You also need a good memory to remember the notes. And playing or singing those notes correctly suggests that your hearing is in excellent condition. Finally ,when a man sings to the woman he loves (or vice versa), it may be a way of showing off.

However ,Miller's theory still doesn't explain why certain combinations

of sounds influence our emotions so deeply. For scientists, this is clearly an area that needs further research. 注释：

1.It is also true that humans，not animals，have developed musical instruments：人研制出了乐器，而动物则不能。develop：研制，例如：Scientists are developing new drugs to treat cancer.科学家们正在研发新药用以治疗癌症。 练习：

1. Humans,but not animals, can sing. A Right B Wrong C Not mentioned

2. People can use music to communicate their emotions. A Right B Wrong C Not mentioned.

3. We use the same part of the brain for music and language. A Right B Wrong C Not mentioned

4. Geoffery Miler has done research on music and emotions. A Right B Wrong C Not mentioned 5. It's hard for humans to compose music. A Right B Wrong C Not mentioned

6. Memory is not an important part in singing in tune. A Right B Wrong C Not mentioned

7. Scientists does not know all the answers about the effects of music on humans.

A Right B Wrong C Not mentioned 答案与题解：

1.B 第二段的第三句：It is true that some animals can sing(and many birds sing better than a lot of people).可以看出有些动物会唱歌，而不只人类会唱歌。

2.A第三段的第三句：However，people can use music to communicate things—especially their

emotions.这句清楚表明，人们可以用音乐来表达情感。

3.B第四段说明：科学证明人们用大脑的不同区域处理语言和音乐。在第五段，作者用Vissarion Shebalin的例子进一步说明人脑处理语言和音乐的位置不同，Shebalin中风以后不能讲话也听不懂别人的话，但他却能创作乐曲。

4.A 第六段的第四句：Geoffrey Miller，a researcher at University College，London，thinks that

music and love have a strong connection.这句说明Miller对音乐和爱(情感)的关系进行了研究，他得出的结论是：音乐和爱有密切的关联。 5.C文中没有提及创作乐曲是否困难。

6.B第六段有一句：You also need a good memory to remember the notes.此句说明必须具备好的记忆力记音符才能唱得符合调子。

7.A最后一段讲的是：科学家们需要做更多的研究才能解释为什么有些声音影响我们的情感会如此之深。也就是说，科学家不能全部解释音乐对人类的影响。

（B）第二十九篇：I'll Be Bach

Composer David Cope is the inventor of a computer program that writes original works of classical music. It took Cope 30 years to develop the software. Now most people can't tell the difference between music by the famous German composer J. S. Bach (1685-1750) and the Bach-like compositions from Cope's computer.

It all started in 1980 in the United States, when Cope was trying to write an opera. He was having trouble thinking of new melodies, so he wrote a computer program to create the melodies. At first this music was not easy to listen to. What did Cope do? He began to rethink how human beings compose music. He realized that composers' brains work like big databases. First, they take in all the music that they have ever heard. Then they take out the music that they dislike. Finally, they make

new music from what is left. According to Cope, only the great composers are able to create the database accurately, remember it, and form new musical patterns from it.

Cope built a huge database of existing music. He began with hundreds of works by Bach. The software analyzed the data: it broke it down into smaller pieces and looked for patterns. It then combined the pieces into new patterns; Before long,the program could compose short Bach-like works. They weren't good, but it was a start.

Cope knew he had more work todo-he had a whole opera to write. He continued to improve the software. Soon it could analyze more. complex music. He also added many other composers, including his own work, to the database., A few years later, Cope's computer program, called \help him with his opera. The process required a lot of collaboration between the composer and Emmy. Cope listened to the computer's musical ideas and used the ones that he liked. With Emmy, the opera took only two weeks to finish. It was called Cradle Falling, and it was a great success! Cope received some of the best reviews of his career, but no one knew exactly how he had composed the work.

Since that first opera, Emmy has written thousands of compositions. Cope still gives Emmy feedback on what he likes and doesn't like of her music ,but she is doing most of the hard work of composing these days! 注释：

1.J.S.Bach：约翰?塞巴斯蒂安?巴赫(德语：Johann Sebastian Bach，1685年3月31日--1750年7月28日)，巴洛克时期的德国作曲家，杰出的管风琴、小提琴、大键琴演奏家，同作曲家亨德尔和泰勒曼齐名。巴赫被普遍认为是音乐史上最重要的作曲家之一，并被尊称为“西方‘现代音乐’之父”，也是西方文化史上最重要的人物之一。 练习：

l.. The music composed by David cope is about

A classical music. B pop music. C drama. D country music. 2. By developing a computer software, David Cope aimed A to be like Bach. B to study Bach.

C to write an opera. D to create a musical database 3. What did Cope realize about a great composer's brain? A It forms new musical patterns all by itself.

B It writes a computer program. C It can recognize any music patterns. D It creates an accurate database. 4. Who is Emmy?

A a database B a computer software C a composer who helped David D an opera 5. We can infer from the passage that A David Cope is a computer programmer. B David Cope loves music. C Bach's music helped him a lot.

D Emmy did much more work than a composer. 答案与题解：

1.A第一段的第一句：David Cope发明了一个可以编写出古典音乐的电脑软件。 2.c从第二段的第一句可以看出，David编写电脑软件的目的是写歌剧。A、B和D都属于创作歌剧的一部分。

3.D第二段的后半部分讲的是伟大的歌剧作者与一般的歌剧作者的不同之处是通过对数据进行准确的构建、记忆而后创作出新的音乐形式。 4.B从第五段第一句可知Emmy是一计算机软件。 ’

5.D从本文第一句可知David是一个作曲家，不是计算机程序员，所以排除A;B、C内容没有提及;从本文的第五段和第六段可知，Emmy大大提高了David的创作速度，最后一句，大部分困难的工作都由Emmy来做，所以作曲家只干一小部分工作。

（A）第十五篇：A Memory Drug?(A级)

It’s difficult to imagine many things that people would welcome more than a memory- enhancing drug. 1 Furthermore, such a drug could help people

remember past experiences more clearly and help us acquire new information more easily for school and at work. As scientists learn more about memory, we are closing in on this tantalizing goal. 1 __________

Some of the most exciting evidence comes from research that has built on earlier finding,, linking LTP2 and memory to identify a gene that improves memory in mice. 2 __________

Mice bred to have extra copies of this gene showed more activity in their NMDA receptors, more LTP, and improved performance on several different memory tasks -- learning a spatial layout3, recognizing familiar objects, and recalling a fear-inducing shock.

If these basic insights about genes, LTP, and the synaptic basis of memory can be translated to people- and that remains to be seen -- they could pave the way for memory-enhancing treatments. 3__________ As exciting as this may sound, it also raises troubling issues. Consider the potential educational implications of memory-enhancing drugs. If memory enhancers were available, children who used them might be able to acquire and retain extraordinary amounts of information, allowing them to progress far more rapidly in school than they could otherwise. How well could the brain handle such an onslaught of information? What happens to children who don't have access to the latest memory enhancers? Are they left behind in school -- and as a result handicapped later in life?

4__________ Imagine that you are applying for a job that requires a good memory, such as a manager at a technology company or a sales position that requires remembering customers' names as well as the attributes of different products and services. Would you take a memory-enhancing drug to increase your chances of landing the position? Would people who felt uncomfortable taking such a drug find themselves cut out of lucrative career opportunities?

Memory drugs might also help take the sting out of disturbing memories that we wish we could forget but can't. The 2004 hit movie Eternal Sunshine of the Spotless Mind told the story of a young man seeking just such freedom from the painful memories of a romantic breakup. As you will see in the section on persistence later in the chapter, emotionally arousing events often create intrusive memories, and researchers have already muted emotional memories with drugs that block the action of key hormones. Should emergency workers who must confront horrifying accident scenes that can burden them with persisting memories be provided with such drugs? Should such drugs be given to rape victims who can't forget the trauma? Memory drugs might provide some relief to such individuals. But could they also interfere with an individual's ability to assimilate and come to

terms with a difficult experience? 5 __________ 注释：

1.As scientists learn more about memory，we are closing in on this tantalizing goal.随着科学家们对记忆了解增多，我们正接近这一诱人的目标。 2.LTP&NMDA：(Lon9—term Potentiation)给突触前纤维一个短暂的高频刺激后，突触传递效率和强度增加几倍且能持续数小时至几天保持这种增强的现象。LTP发现海马LTP可能是学习记忆的分子基础。1973年Bliss及其合作者，电刺激麻醉兔的内嗅皮层，使海马表层的穿通纤维兴奋，可在齿状回记录到场电位。先用高频电刺激几秒钟后，再用单个电刺激，记录到的部分场电位幅度大大超过原先记录的对照值,并可持续几小时，几天。这一现象称为长时程增强效应(LTP)。1983年发现NMDA(N一甲基一D一门冬氨酸)受体通道复合体在LTP过程中起重要作用，进一步深化了对LTP在大脑学习记忆中作用的理解。 3.a spatial layout：空间布局

4.Memory drugs might also help take the sting out of disturbing memories that we wish we could forget but Can’t：增强记忆药对我们想忘记却又不能的令人烦扰的记忆变得令人易于接受。take the sting out of：使??易于被接受;使??令人感到愉快

5.But could they also interfere with an individual’S ability to assimilate and come to terms with a difficult experience?中的come to terms with：让步;屈服 练习：

A Like steroids for bulking up the muscles,these drugs would bulk up memory.

B A memory enhancer could help eliminate forgetting associated with aging and disease.

C What are the potential implications of memory-enhancing drugs for the workplace?

D We may find ourselves struggling with these kinds of questions in the not-too-distant future.

E There is a pill that you could take every day to allow you to remember everything.

F The gene makes a protein that assists the NMDA2 receptor, which plays an important role in long-term memory by helping to initiate LTP.

答案与题解：

1.B依据上一句的“很难想象一种提高人们记忆力的药会受到人们吹捧”;下面应该对这一现象做出解释，即这种药物有什么疗效;而后一句的Furthermore这一指示词起到了递进的作用，进一步说明这种药物的益处。More than：非常，极其，十分

2.F前一句的关键词是gene、LTP和mice，它讲的是有些令人兴奋的证据是从研究中得出的;该研究基于早期连接LTP和记忆的发现，该结果确定了提高老鼠记忆的基因;而后一句进一步阐述这一发现，开头的mice可以是一个连接词。 3.A前一句讲：如果这种结果用于人类的话，人们就有可能把提高人的记忆力用于临床。这一句讲：就像类固醇用于提高人的肌肉能力，这种药物也可以提高人的记忆力。

4.C一般情况下，每一段的第一句都是本段的主题句。而该句是一个问句：这种提高记忆力的药物用于职场有什么潜在的启示呢?紧接着本段其余几句都提出关于这种药物是否会职场的提升有什么影响的问题。

5.D本句是全文的最后一句。应该是总结性的。鉴于前面都列举了这种提高记忆力的药所面临的一系列问题，所以，我们在不久的将来要面临这些问题。

（B）第十篇： How Deafness Makes It Easier to Hear

Most people think of Beethoven's hearing loss as an obstacle to composing music.

However, he produced his most powerful works in the last decade of his life when he was completely deaf.

This is one of the most glorious cases of the triumph of will over adversity, but his

biographer, Maynard Solomon, takes a different view. l . In his deaf world Beethoven

could experiment, free from the sounds of the outside world, free to create new forms and harmonies.

Hearing loss does not seem to affect the musical ability of musicians who become deaf. They continue to \accuracy than if they were actually hearing it being played.

2 . He described a fascinating phenomenon that happened within three months:\former musical experiences began to play back to me. I couldn't differentiate between what I heard and real hearing. After many years, it is still rewarding to listen to these playbacks, to 'hear' music which is new to me and to find many quiet accompaniments for ali of my moods. \

How is it that the world we see, touch, hear, and smell is both \there\and at the same time within us? There is no better example of this connection between external stimulus and internal perception than the cochlear implant. 3 . However,it might be possible to use the brain's remarkable power to make sense of the electrical signals the implant produces.

When Michael Edgar first \he heard were not at all Clear. Gradually, with much hard work, he began to identify everyday sounds. For example,\telephone became clear almost at once. \

The primary purpose of the implant is to allow communication with others. When people

spoke to Eagar, he heard their voices \through like a long-distance telephone call on

a poor connection. \was of no help.

4 . He said, \same time.

The movement of my fingers and the feel of the keys give added ' clarity' to hearing in my head. \

Cochlear implants allow the deaf to hear again in a way that is not perfect, but which can

change their lives. 5 . Even the most amazing cochlear implants would have been useless to Beethoven as he composed his Ninth Symphony at the end of his life. 注释：

1. the triumph of will over adversity:the successful overcoming of difficulty through determination用意志力战胜不幸

2. I couldn't differentiate between what/heard and real hearing: 我无法区别真正听到的和曾经听过的声音。

3. cochlear implant:a device, surgically placed in the ear, that changes sounds into electric signals 人工耳蜗;耳蜗植入

4. But when it came to his beloved mumble,flag, implant was of no help. 但是，当听到钟爱的音乐时，人工耳蜗就毫无用处(我不用人工耳蜗就能听出来)。 5. The movement of my fingers and the feel of the keys give added clarity to hearing in my head:我手指的移动以及对琴键的感觉使我听到的声音在脑海里更加清晰 练习：

A No man-made device could replace the ability to hear. B When he wanted to appreciate music,Eagar played the piano.

C Still, as Michael Eagar discovered, when it comes to musical harmonies,hearing is irrelevant.

D Michael Eagar, who died in 2003,became deaf at the age of 21. E Beethoven produced his most wonderful works after he became deaf. F Solomon argues that Beethoven's deafness \as a composer. 答案与题解：

1.F本段的开头讲：贝多芬的例子是一个意志力战胜失聪的极好的例子。但是，他的传记作家Maynard Solomon却持不同的意见。贝多芬的失聪不是一种灾难;相反，对他成为作曲家起到了促进作用。后一句解释了失聪是如何使贝多芬更好地创作。

2.D该句是本段的开头，根据后一句：他描述了在3个月之内发生的奇妙的现象：我之前的音乐经历开始在脑中回放。再有后一句的what I heard and real hearing可以判定D是恰当的。

3.A依据前一句：只有人工耳蜗才能使外部刺激和内心感知联系起来(失聪的人通过人工耳

蜗听到外部的声音)。人工耳蜗就是一种man-made device，后一句也是在讲人工耳蜗的功能。所以A是对的。

4.B依据后一句的play the piano呼应When he wanted to appreciate music.Eagar played the piano，可以断定答案为B。

5.C前一句讲人工耳蜗的作用：它能使失聪的人听到声音，尽管不完美，但改变了他们的生活;Still表示转折，该句承上启下，虽然人工耳蜗能帮助失聪的人，但谈到音乐的和声时听力就无关紧要了(听力不起作用)。所以后一句讲贝多芬在他生命的最后时刻创作第九交响曲时，无论多么完美的人工耳蜗对他来说都没有用。

（C）第四篇：The Bilingual Brain

When Karl Kim immigrated to the United States from Korea as a teenager, he had a hard time learning English. Now he speaks it fluently, and he had a unique opportunity to see how our brains adapt to a second language. As a graduate student, Kim worked in the lab of Joy Hirsch, a

neuroscientist in New York. 1 They found evidence that children and adults don't use the same parts of the brain when they learn a second language. The researchers used an instrument called an MRI ( magnetic resonance imaging) scanner to study the brains of two groups of bilingual people 2 . The other consisted of people who, like Kim, learned their second language later in life.People from both groups were placed inside the MRI scanner. This allowed Kim and Hirsch to see which parts of the brain were getting more blood and were more active. They asked people from both groups to think about what they had done the day before, first in one language and then the other. They couldn't speak out loud because any movement would disrupt the scanning.

Kim and Hirsch looked specifically at two language centers in the brain, Broca's area, which is believed to control speech production, and Wernicke's area, which is thought to process

meaning. Kim and Hirsch found that both groups of people used the same part of Wernicke's area no matter what language they were speaking. 3 People who learned a second language as children used the same region in Broca's area for both their first and second languages. People who learned a second language later in life used a different part of Broca's area for

their second language. 4 Hirsch believes that when

language is first being programmed in young children, their brains may mix the sounds and

structures of all languages in the same area. Once that programming is complete, the processing of a new language must be taken over by a different part of the brain.

A second possibility is simply that we may acquire languages differently as children than we do as adults. Hirsch thinks that mothers teach a baby to speak by using different methods involving touch, sound, and sight. 5 注释：

1.Now he speaks it fluently，and he had a unique opportunity to see how our brains adapt to a

second language：现在他英语讲得很流利，并且有一个独特的机会来审视我们的大脑是如何适应第二语言的。adapt to：适应。 2.MRI(magnetic resonance imaging)：核磁共振成像

3.Broca’S area&Wernicke’S area：Broca’s area,即布洛卡区，也译为布罗卡区，是大脑的一区，它主管语言信息的处理、话语的产生。Wemicke’s area，即韦尼克区，也译为威尼克区，是大脑写中枢，视觉性语言中枢。Broca’s area与Wernicke’s area共同形成语言系统。布洛卡区与韦尼克区通常位于脑部的优势半脑(通常位于左侧)，这是由于大多数人(97%)是右利的缘故。1861年法国神经学家兼外科医生保罗?布洛卡(Paul Broca,1824--1880)对一些失语症患者进行研究及治疗时发现此一区域，位于大脑皮层额下回后部的441区,45区，故以发现者的名字命名为布洛卡区。 练习：

A But their use of Broca's area was different.

B One group consisted of those who had learned a second language as children.

C How does Hirsch explain this difference?

D We use special parts of the brain for language leaming.

E And that is very different from learning a language in a high school or college class.

F Their work led to an important discovery. 答案与题解：

1.F根据本空的后一句：They found evidence that children and adults don’t use the same parts of the brain when they learn a second language.其中they found evidence与discovery相呼应。

2.B 依据本空的后一句The other consisted of people wh0，like Kim，learned their second language later in life.one?the other是固定搭配，用来比较同类事物。

3.A整段讲的是对大脑的两个语言中心的分析，得出两组测试人员都使用Wernicke’S area中同一部位，紧接着即谈到测试者们使用Broca’S area的情况。

4.C本段的开头谈到孩子学习第一和第二语言都用Broca’S area相同的部位;而成人学习第二语言时使用Broca’s area不同的部位。后面都是Hirsch对这一现象的解释;Hirsch believes...根据上下文C是恰当的。

5.E该句是全文的结束语。本段前两句都讲成年人与小孩习得语言方式的不同，Hirsch认为，母亲教小孩说话是通过使用不同的方法，涉及触觉、听觉和视觉。different是关键词，所以，我们在高中或大学的课堂上学习语言的方法和母亲教孩子的方法是不同的。
