Einstein added that if something such as a ruler was moving, it would seem to get shorter and shorter . A. when it was moving faster and faster B. because the ruler itself was short C. because we can't see it clearly D. because the ruler was broken into pieces B Until late in the 20th century most Americans spent time with people of different generations. Now middle-aged Americans may not keep in touch with old people until they are old themselves. That's because we group people by age. We put our three-year-olds together in day-care centers, our 13-year-olds in schools and sport activities, and our 80-year-olds in senior citizen homes. Why? We live far away from the old for many reasons. Young people sometimes avoid the old to get rid of fears of aging and dying. It is much harder to watch someone we love disappear before our eyes. Sometimes it's got hard that we stay away from the people who need us the most. Fortunately, some of us have found our way to the old. And we have discovered that they often save the young. A reporter moved her family into a block filled with old people. At first her children were disappointed. But the reporter baked banana bread for the neighbors and had her children deliver it and visit them. Soon the children had many new friends, with whom they shared food, stories and projects. "My children have never been lonely, " the reporter said. The young, in turn, save the old. Once I was in a rest home when a visitor showed up with a baby, she was immediately surrounded. People who hadn't gotten out of bed in a week suddenly were ringing for a wheelchair. Even those who had seemed asleep woke up to watch the child. Babies have an astonishing power to comfort and cure. Grandparents are a special case. They give their grandchildren a feeling of safety and continuity. As my husband put it "My grandparents gave me a deep sense that things would turn out right in the end." Grandchildren speak of attention they don't get from worried parents. "My parents were always telling me to hurry up, and my grandparents told me to slow down," one friend said. A teacher told me she can tell which pupils have relationships with grandparents: they are quieter, calmer and more trusting. 【查看更多】

      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.
