题目列表(包括答案和解析)
Do you want to live another 100 years or more? Some experts say that scientific advances will one day enable humans to last tens of years beyond what is now seen as the natural limit of the human life span.
“ I think we are knocking at the door of immortality (永生),” said Michael Zey, a Montclair State University business professor and author of two books on the future. “ I think by 2075 we will see it and that’s a conservative estimate.”
At the conference in San Francisco, Donald Louria, a professor at New Jersey Medical School in Newark said advances in using genes as well as nanotechnology(纳米技术) make it likely that humans will live in the future beyond what has been possible in the past. “ There is a great push so that people can live from 120 to 180 years,” he said. “ Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years.”
However, many scientists who specialize in aging are doubtful about it and say the human body is just not designed to last about 120 years. Even with healthier lifestyles and less disease, they say failure of the brain and organs will finally lead all humans to death.
Scientists also differ on what kind of life the super aged might live. “ It remains to be seen if you pass 120, you know; could you be healthy enough to have good quality of life?” said Leonard Poon, director of the University of Georgia Gerontology Center. “ At present people who could get to that point are not in good health at all.”

Most people want to know how things are made.They honestly admit,however,that they hardly know a thing when it comes to understanding how a piece of music is made.Where a composer(作曲家) begins,how he manages to keep going—in fact,how and where he learns his trade—all are covered in complete darkness.The composer,in short,is a man of mystery(神秘).
One of the first things the common man wants to know about is the part inspiration(灵感) plays in a composer’s work.He finds it difficult to believe that composers are not much interested in that question.Writing music is as natural for the composer as eating or sleeping for all.Music is something that the composer happens to have been born for.
The composer,therefore,does not say to himself:“Do I feel inspired?”He says to himself:“Do I feel like working today?”And if he feels like working,he does.It is more or less like saying to himself:“Do I feel sleepy?”If you feel sleepy,you go to sleep.If you don’t feel sleepy,you stay up.If the composer doesn’t feel like working,he doesn’t work.It’s as simple as that.
What would be the best title for the text?
A.Composer:a man of mystery
B.Practice makes good music
C.Relation between sleeping and music
D.Music:product of nature

Most people want to know how things are made. They honestly admit, however, that they hard??ly know a thing when it comes to understanding how a piece of music is made. Where a composer (作曲家) begins, how he manages to keep going - in fact, how and where he leams his trade -all are covered in complete darkness. The composer, in short, is a man of mystery. (神秘).
One of the first things the common man wants to know about is the part inspiration (灵感) plays in a composer' s work. He finds it difficult to believe that composers are not much interested in that question. Writing music is as natural for the composer as eating or sleeping for all. Music is something that the composer happens to have been born for.
The composer, therefore, does not say to himself: "Do I feel inspired?" He says to himself:
"Do I feel like working today?" And if he feels like working, he does. It is more or less like saying to himself: "Do I feel sleepy?" If you feel sleepy, you go to sleep. If you don't feel sleepy, you stay up. If the composer doesn' t feel like working, he doesn' t work. It' s as simple as that.
