21、No one is glad to hear that his body has to be cut open by a surgeon and part of it taken out. Today, however, we needn't worry about feeling pain during the operation. The sick person falls into a kind of sleep, and when he awakes, the operation is finished. But these happy conditions are fairly new. It is not many years since a man who had to have operation felt all its pain.
Long ago, operation had usually to be done while the sick man could feel everything. Soon after 1770, Josept Priestley discovered a gas which is now called "laughing gas". Laughing gas became known in America. Young men and women went to parties to try it. Most of them spent their time laughing, but one man at a party, Horace Wells, noticed that people didn't seem to feel pain when they were using this gas. He decided to make an experiment on himself. He asked a friend to help him.
Wells took some of the gas, and his friend pulled out one of Well's teeth. Wells felt no pain at all.
As he didn't know enough about laughing gas, he gave a man less gas than he should have. The man cried out with pain when his tooth was being pulled out.
Wells tried again, but this time he gave too much of the gas, and the man died. Wells never forgot this terrible event.

24、In the high mountain country outside the city of Toluker, there stands a prison. This prison is quite different from other prisons in the world. The guards, except for two at the main gate, are not armed. There are many remarkable things about Toluker prison. For example, of the 15,000 individuals who have been in prison at Toluker, less than two percent have got into trouble again with the law. Men in the open prison are free to find work outside, but go back to prison each night. On weekends they are allowed to go home. When most other prisons are still sending criminals back into society, Toluker is returning people who stand on their own feet and contribute to society. In 1974, a prisoner called Barb Crook moved to the open prison. A year later, he left Toluker for the last time. He was then nearly forty-six and had been in prison for fourteen years. He got a job as construction worker in the city, remarried and was regarded as a useful person of his community. If you ask Bob why Toluker works, he would say, "Because they believed in me when I was at my worst."

27、Hobbs was an orphan. He worked in a factory and every day he got a little money. Hard work changed him thin and weak. He wanted to borrow a lot of money to learn to paint pictures, but he did not think he could pay off the debts.
One day a lawyer said to him, “One thousand dollars, and here is the money.” As Hobbs took the package of notes, he was very dumbfounded(惊呆了的). He didn't know where the money came from and how to spend it. He said to himself, “I could go to find a hotel and live like a rich man for a few days, or I give up my work in the factory and do what I'd like to do: painting pictures. I could do that for a few weeks, but what would I do after that? I should have lost my place in the factory and have no money to live on. If it were a little less money, I would buy a new coat, or a radio, or give a dinner to my friends. If it were more, I could give up the work and pay for painting the pictures. But it is too much for one and too little for the other.”
“Here is the reading of your uncle's will,” said the lawyer, “telling what is to be done with this money after his death. I must ask you to remember one point. Your uncle has said you must bring me a paper showing exactly what you did with his money, as soon as you have spent it.”
“Yes, I see. I will do that,” said the young man.

28、There are many misunderstandings about American Indian names. Crazy Horses, for example, was given to a man because he was courageous, not because he was mad.
Indian families had no last names. The Sioux Indians give individuals three or four names. The first name was given at birth. It showed the order of a birth into the family. Wenonah, for instance, meant "firstborn daughter".
The second name, the honor name, was given to the child by a medicine man. It usually referred to the fine character of good deeds of one of the child's ancestors. When he grew up, the person was expected to live up to this name. Otherwise, the person might not be called by it.
The third name was the nickname. It usually referred to something odd that the person had done. It was hardly ever flattering(奉承).
The fourth name came the deed name. It was given by a war chief after the person accomplished some good or extraordinary bravery. The name might be that of a fear-inspiring animal such as Bear or Buffalo or that of a noble bird, such as Eagle, Hawk or Owl.

30、Hi, dear boys and girls! Do you know how to be a healthy kid? Here are some rules you should follow.
First, eat different foods, especially fruit and vegetables. You may have a favourite food, but you'd better eat something different, if you eat different foods, you will probably get more nutrients (营养物质) your body needs.
Second, drink water and milk as often as possible. When you're really thirsty, cold water is the No. l choice. Milk is a great drink that can give you more calcium (钙) your body needs to grow strong bones.
Third, listen to your body. How do you feel when you are full? When you are eating, notice how your body feels and when your stomach feels comfortably full. Eating too much will not make you feel comfortable and make you fat.
Fourth, limit screen time. Screen time is the time you watch TV, DVDs and videos, or using computers. It is good to take more exercise such as basketball, bike riding and swimming. You can't watch TV for more than two hours a day.
Fifth, be active. One thing you'd like to do as a kid is to find out which activity you like best. Find ways to be active every day.
Follow these rules and you can be a healthy kid.
