An American named Crum invented potato chips in 1853, although that was not his intention (意图). He was a chef(厨师长) at a beautiful restaurant in Saratoga Springs, New York. A regular dish on the menu was fried (油炸的) potatoes, which was an idea that had started in France. At that time, French fried potatoes were cut into thick slices (片).

      One day, a dinner guest at the restaurant sent back his fried potatoes to the chef because he did not like them so thick. So Mr. Crum cut the potatoes a little thinner and fried them. The guest did not like those either. That made Mr. Crum angry, so he thought he would just show the man. He sliced the potatoes paper-thin and fried them, thinking that the man would say nothing about it. However, to his surprise, the man loved the thin potatoes very much. Other guests tried them and also liked them. So, Mr. Crum's potato chips were added to the menu. They were called Saratoga Chips.

      Finally, Mr. Crum opened his own restaurant to sell his famous chips. Now potato chips are packaged (包装) and sold in stores.

    Bell was a British teacher to deaf people. He was born in Scotland in 1847 and went to school in London. Bell was interested in helping deaf people to learn to speak. He taught people how to use their mouths to make the sounds needed for talking.

    Bell's family moved to Canada in 1870 and to the USA in 1871. For several years he taught the people who could not speak in Boston. But at the same time he was developing a way to use electricity to send the sounds of talking along a wire, and he made the first telephone in June, 1875.

    The telephone developed quickly in the USA over the next few years. The Bell Telephone Company started in 1877, and in 1878 the first telephone centre was built in New York. More than 150,000 people had telephones in their homes ten years later. Bell was a kind man and spent much of his money and time during the rest of his life helping deaf people. In 1922 he died in Canada.
