　　3.Television was invented by John Logie Baird. When he was young he built an aeroplane. He tried to fly in it, but it crashed down below. However, Baird was fortunate not to be killed. It did not discourage him. Instead, when he was older he tried to make diamonds from coal. The only result was an enormous explosion. Yet he was not injured. Then, he became a businessman. When his business failed, he thought of working at television. His family advised him not to, but he did not listen to them. He rented an attic, bought the apparatus he needed and started working. Although he worked for a long time, he was not successful. One day he saw a picture on his screen. So he rushed out to get someone he could televise . He found an office boy and took him back to his room. However, no image of the boy appeared on his screen. The boy, terrified, had put his head down. When he put it up again, his picture appeared on the screen. That s how television had been discovered.

　　4.In the United Stated there is a belief that people are rewarded for working, producing, and achieving. Many people believe that there is equality of opportunity that allows anyone to become successful. This belief is illustrated by stories written by a nineteenth-century American novelist, Horatio Alger, who wrote about the American Dream . In his stories he described poor people who became rich because of their hard work, honesty, and luck. The stories reinforced the idea that all individuals, no matter how poor, were capable of becoming wealthy as long as they were honest and hard-working. For many Americans, however, Horatio Alger s rags-to-riches stories do not represent the reality of opportunity. Many poor immigrants who came to the United States in the nineteenth and twentieth centuries were able to become rich. Today, however, the poor generally do not rise to the middle and upper classes. That is why the American Dream is now described as a myth.

　　5.There were once a dog and a cat sitting by a kitchen door when the cook came out and threw several pieces of meat to them. They both sprang to get the meat, but the dog was the stronger. He ate it all himself. This was selfishness, by which I mean that the dog cared only for himself. Was this wrong? No, the dog knew no better. But men are different from dogs and follow a different rule of conduct. How miserable we should all be if every person were to care only for himself! We ought to be thankful that we have a higher nature than that of beasts and are able to see and feel the duty of being kind and affectionate to one another. And as we can see and feel this duty, we ought to be very careful always to observe it.
