          題目列表(包括答案和解析)

          Last evening I was watching the evening news on television. The news was about a prize for scientific  1   ;I forgot what it was. The announcer, whose name was Ralph Story, said something that caught my  2  .“All great discoveries,”he said,“are made by people between the ages of twenty-five and thirty.”  3   a little over thirty myself, I wanted to disagree with him.  4   wants to think that he is past the age of making any discovery. The next day I happened to be in the public library and spent several hours looking up the  5  of famous people and their discoveries. Ralph was right.

          First I looked at some of the   6   discoveries. One of the earliest discoveries, the famous experiment that proved that bodies of different  7   fall at the same speed, was made by Galileo when he was 26. Madam Curie started her research that  8   to the Nobel Prize when she was 28. Einstein was 26 when he published his world-changing theory of relativity. Well,  9   of that. Yet I  10   if those“best years”were true in other  11   .

          Then how about the field of   12   ? Surely it needs the wisdom of age to make a good leader. Perhaps it  13   ,but look when these people  14   their career. Winston Churchill was elected to the House of Commons at the age of 26. Abraham Lincoln  15   the life of a country lawyer and was elected to government. At what age? Twenty-six.

          But why  16   best years some after thirty? After thirty, I  17   ,most people do not want to take risks or try   18   ways. Then I thought of people like Shakespeare and Picasso. The former was writing wonderful works at the ripe age of fifty, while the latter was  19   trying new ways of painting when he was ninety!

          Perhaps there is still  20   for me.
