阅读下列短文,从每题所给的四个选项中,选出最佳选项。

      Albert Einstein (1879 ~ 1955) was one of the greatest and most original scientific thinkers of all time.

      Born of Jewish parents at Ulm in Germany, he completed his education in Switzerland and got his Ph.D at the University of Zurich. He went to live in the United States in 1933 because of the rise of Nazism(纳粹) in Germany and Hitler's persecution(迫害) of the Jews.

       In 1905, while still at Zurich, he published his Special Theory of Relativity,which was based on things everyone may have noticed. If two trains are standing alongside each other and one train starts to move,a

person sitting in the train may wonder whether his own train is moving or the other is moving, and before

he finds out what is happening,he can see that one train is moving relatively to the other. From this and

also from other more complicated facts, Einstein came to the conclusion that all motion is relative and that

there are really no such things as absolute(绝对) motion. Some of the other conclusions he drew are that

nothing can go faster than light,and that if something such as a ruler was moving faster and faster it would

seem to get shorter and shorter as its speed was near the speed of light. By 1915,Einstein had made

known his General Theory of Relativity. He also improved on Newton's theory of gravity. Most of his

theories have been tested and found to be true though some may sound strange. For his  important work

he was awarded the 1921 Nobel Prize for Physics.
