It took Cope 30 years to develop the software. Now most people cant tell the difference between music by the famous German composer J. S. Bach (1685-1750) and the Bach-like compositions from Copes 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 werent good, but it was a start. Cope knew he had more work to do-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, Copes computer program, called "Emmy", was ready to help him with his opera. The process required a lot of collaboration between the composer and Emmy. Cope listened to the computers 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 doesnt like of her music, but she is doing most of the hard work of composing these days! 注釋：1.J.S.Bach：約翰.塞巴斯蒂安.巴赫(德語：JohannSebastianBach，1685年3月31日-1750年7月28日)，巴洛克時(shí)期的德國(guó)作曲家，杰出的管風(fēng)琴、小提琴、大鍵琴演奏家，同作曲家亨德爾和泰勒曼齊名。巴赫被普遍認(rèn)為是音樂史上最重要的作曲家之一，并被尊稱為“西方現(xiàn)代音樂之父”，也是西方文化史上最重要的人物之一。練習(xí)：l.ThemusiccomposedbyDavidcopeisaboutAclassicalmusic.

In other words, girls may end up learning math anxiety from their teachers4. The study suggests that if these girls grow up believing that boys are better at math than girls are, then these girls may not do as well as they would have if they were more confident."如果一直由對(duì)數(shù)學(xué)有焦慮的女教師教授數(shù)學(xué)，就會(huì)對(duì)她們的數(shù)學(xué)成績(jī)產(chǎn)生雪球效應(yīng)"，Levine說。換言之，女孩子們最后從老師那里獲得的是對(duì)數(shù)學(xué)的焦慮。該研究表明，如果女孩子們?cè)谝粋€(gè)認(rèn)為男孩比女孩數(shù)學(xué)好的環(huán)境中成長(zhǎng)，那么她們的數(shù)學(xué)可能會(huì)不如在更自信的狀態(tài)下學(xué)得好。3.Just as students find certain subjects to be difficult, teachers can find certain subjects to be difficult to learn - and teach. The subject of math can be particularly difficult for everyone. Researchers use the word "anxiety" to describe such feelings: anxiety is uneasiness or worry.如同學(xué)生，教師也會(huì)覺得某些學(xué)科難學(xué)和難教，數(shù)學(xué)可能對(duì)每一個(gè)人來說尤其難。這就是研究者所言的"焦慮"：不自信或擔(dān)心。4.The new study found that when a teacher has anxiety about math, that feeling can influence how her female students feel about math. The study involved 65 girls, 52 boys and 17 first- and second-grade teachers in elementary schools in the Midwest. The students took math achievement tests at the beginning and end of the school year, and the researchers compared the scores.此研究發(fā)現(xiàn)，教師對(duì)數(shù)學(xué)的焦慮能夠傳染給她的女學(xué)生們。該研究的研究對(duì)象包括65個(gè)女孩，52個(gè)男孩和17位在中西部教一二年級(jí)的教師。學(xué)生們?cè)趯W(xué)年的開始和結(jié)束時(shí)都進(jìn)行數(shù)學(xué)測(cè)試，研究者們比較得分。5.The researchers also gave the students tests to tell whether the students believed that a math superstar had to be a boy. Then the researchers turned to the teachers: To find out which teachers were anxious about math, the researchers asked the teachers how they felt at times when they came across math, such as when reading a sales receipt銷售清單5. A teacher who got nervous looking at the numbers on a sales receipt銷售清單, for example,was probably anxious about math.研究者們測(cè)試學(xué)生是否認(rèn)為數(shù)學(xué)明星一定會(huì)是男孩。然后研究者們測(cè)試教師，試圖找出哪些教師對(duì)數(shù)學(xué)感到焦慮，研究者們問教師們當(dāng)碰到數(shù)學(xué)問題諸如閱讀銷售清單時(shí)的感受，如果一位教師一看到銷售清單的數(shù)字就感到緊張，那么她很可能對(duì)數(shù)學(xué)存在焦慮。6. Boys,on average,were unaffected by a teachers anxiety. On average, girls with math-anxious teachers scored lower on the end-of-the-year math tests than other girls in the study did. Plus,on the test showing whether someone thought a math superstar had to be a boy, 20 girls showed feeling that boys would be better at math - and all of these girls had been taught by female teachers who had math anxiety.平均來說，教師的焦慮不會(huì)影響到男孩子。但是，一般說來，如果教女孩子的教師有數(shù)學(xué)焦慮癥，那么女孩子們?cè)趯W(xué)年結(jié)束時(shí)測(cè)試得分比其他的女孩要低。另外，在關(guān)于是否認(rèn)為數(shù)學(xué)明星應(yīng)該是男孩的測(cè)試中，有20個(gè)女孩認(rèn)為男孩數(shù)學(xué)比女孩好，這20個(gè)女孩的老師都是女性，且都患有數(shù)學(xué)焦慮癥。"This is an interesting study, but the results need to be interpreted解釋 as preliminary and in need of replication with a larger sample6," said David Geary, a psychologist at the University of Missouri7 in Columbia.來自密蘇里大學(xué)的心理學(xué)家David Geary說"這是一個(gè)有趣的研究，但是這只是初步結(jié)果，需要用更大的調(diào)查樣本進(jìn)行重復(fù)驗(yàn)證"。練習(xí)：1.
