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。
