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 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 plex 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(合作) 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（反馈) on what he likes and doesnt like of her music, but she is doing most of the hard work of composing these days！ 9. what led david cope to invent software?a. he had difficulties in writing an opera. b. he dreamed of developing software.c. he wanted to help composers. d. he was fond of classical music.10. what do we know about david cope?a. his cradle falling wasnt popular.b. he had kept on improving his software.c. he composed bach-like works well at the beginning.d. he has shifted his attention to invent different software.11. it can be learnt from the text that _.a. copes database includes bachs works only. b. bachs music helped cope a lot.c. cope is a computer programmer. d. emmy did much more work than cope in composing.12. what is the best title for the text?a. the invention of a software for creating music b. ways to create a music databasec. david cope-a music genius d. how to start creating musicda
