Perhaps the most famous name in the world of sileni movies is Charlie Chaplin. It was in 1889 that both moving pictures and Charlie Chaplin were born. Sadly, Charlie's father died when Charlie was five, and his mother was sent to mental hospital. This left young Charlie homeless and living on the streets.,
Things seemed bad for Charlie, but he had a bright, nice character. He was pleasant and easy to like. So he managed to get small parts in Derformances around London. Then he moved to the USA in 1906, and his life took a major change for the better. He got a part in a show performing there. Seven years after his arrival in the USA, he got his first major part in a film. Charlie was a great success in the movie theaters. His silent, highly visual(视觉的) form of comedy was perfect for the silent films of the time. By 1915, he was making over $1,250 a week, which was a huge amount of money at that time. Charlie knew what he was good at, and he stuck to it. Even when sound could be used for movies in 1923, he continued to make silent pictures, Charlie knew that the silence was an essential part of what made his movies so funny. Charlie continued to make silent films well into the 1940s, when almost everyone else had changed to sound. Charlie, however, still remained one of the world's greatest film stars.

，可见．转速n增大时，弹力F也增大，而摩擦力不变．故C错误．如转速不变，筒壁对衣服的弹力随着衣服含水量的减少，则所需要的向心力减小，所以筒壁对衣服的弹力也减小．故D正确．
