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.______(46)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.______(47)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._______(48)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.______(49)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! ______(50) 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!

There are three kinds of goals: short-term,medium-range and long-term goals. Short-range goals are those that usually deal with current activities,which we can apply on a daily basis.Such goals can be achieved in a week or less,or two weeks,or possible months.It should be remembered that just as a building is no stronger than its foundation ,out long-term goals cannot amount to very munch without the achievement of solid short-term goals.Upon completing our short-term goals,we should date the occasion and then add new short-term goals that will build on those that have been completed.
The intermediate goals bukld on the foundation of the short-range goals.They might deal with just one term of school or the entire school year,or they could even extend for several years.Any time you move a step at a time,you should never allow yourself to become discouraged or overwhelmed. As you complete each step,you will enforce the belief in your ability to grow adn succeed.And as your list of completion dates grow,your motivation and desire will increase.
Long-range goals may be related to our dreams of the future. They might cover five years or more. Life is not a static thing.We should never allow a long-term goal to limit us or our course of action.
It is implied but not stated in the passage that ______.

A.those who habe long-term goals will succeed
B.writing down the dates may discourage you
C.the goal is only a guide for us to reach our desination
