It is difficult for doctors to help a person with a damaged brain. Without enough blood, the brain lives for only three to five minutes. More often the doctors can't fix the damage. Sometimes they are afraid to try something to help because it is dangerous to work on the brain. The doctors might make the person worse if he operates on the brain.
Dr. Robert White, a famous professor and doctor, thinks he knows a way to help. He thinks doctors should make the brain very cold. If it is very cold, the brain can live without blood for 30 minutes. This gives the doctor a longer time to do something for the brain.
Dr. White tried his idea on 13 monkeys. First he taught them to do different jobs, then he operated on them. He made the monkeys' blood go through a machine. The machine cooled the blood. Then the machine sent the blood back to the monkeys' brains. When the brain's temperature was 10°C, Dr. White stopped the blood to the brain. After 30 minutes he turned the blood back on. He warmed the blood again. After their operations the monkeys were like they had been before. They were healthy and busy. Each one could still do the jobs the doctor had taught them.

Hello! My name is Lisa, and I am a lioness. I live on the open grasslands of Africa with my family. Lions living in a group are called a pride.
My father is strong and powerful. He and his cousin are the leaders of our pride. The other members are my mother, her sisters, and their children.
The area where a pride lives is big! We roar (咆哮) to tell each other where we are and to warn strangers to stay away.
Meet my new baby brother. His name is Leon. See the spots on his fur? We lions are born spotted or striped (有条纹的). As we grow older, the spots gradually disappear.
Lionesses usually spend their entire lives with their birth pride, but Leon will leave when he is about three years old. He’ll run around with a male (雄性的) friend or relative for a few years until they take over a pride of their own.
But for now, we have lots of fun together. We often play and fight for hours, which can help us practice skills that we will need for hunting.
We lions keep ourselves very clean. Just like a house cat, I clean my fur (毛) with my tongue. We clean for each other, too, to show we’re friends.
Lions like to sleep for most of the day. We hunt in the cool evening. Female (雌性的) lions hunt more often than male lions. We work together as a team. At the right moment, we attack and kill our prey. Then we share it. Male lions usually eat first. Females eat next. Baby lions are the last to eat. The smallest one gets the least food.
Since we are full, it’s time to go to find a nice place for a sleep. Bye!

In modern society there is a great deal of argument about competition. Some value it highly, believing that it is responsible for social progress and prosperity; others say that competition is bad; that it sets one person against another; that it leads to unfriendly relationship between people.
I have taught many children who held the belief that their self-worth relied on how well they performed at tennis and other skills. For them, playing well and winning are often life-and-death affairs. In their single-minded pursuit of success, the development of many other human qualities is sadly forgotten.
However, while some seem to be lost in the desire to succeed, others take an opposite attitude. In a culture which values only the winner and pays no attention to the ordinary players, they strongly blame competition. Among the most vocal are youngsters who have suffered under competitive pressures from their parents or society. Teaching these young people, I often observe in them a desire to fail. They seem to seek failure by not trying to win or achieve success. By not trying, they always have an excuse: “I may have lost, but it doesn’t matter because I really didn’t try.” What is not usually admitted by themselves is the belief that if they had really tried and lost, that would mean a lot. Such a loss would be a measure of their worth. Clearly, this belief is the same as that of the true competitors who try to prove themselves. Both are based on the mistaken belief that one’s self-respect relies on how well one performs in comparison with others. Both are afraid of not being valued. Only as this basic and often troublesome fear begins to dissolve can we discover a new meaning in competition.
