    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.【B1】______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.【B2】______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.【B3】______They weren’ t 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, Cope’s computer program, called "Emmy" , was ready to help him with his opera. 【B4】______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!【B5】______
    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!
A. By developing a computer software, David Cope aimed to write an opera.
B. Cope received some of the best reviews of his career, but no one knew exactly how he had composed the work.
C. He was having trouble thinking of new melodies, so he wrote a computer program to create the melodies.
D. The process required a lot of collaboration between the composer and Emmy.
E. Before long, the program could compose short Bach-like works.
F. Then they take out the music that they dislike.
【B2】
选项
答案F
解析 根据空格前一句的第一个单词“First”与空格后一句的第一个单词“Finally”可知，空格处的句子中应该有一个表示顺序的词，只有F项中的“Then”可以表示顺序。这三句话连用，用来解释Cope用软件来编写音乐的先后顺序，符合题意。由此可知，本题应该选择F项。
