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, and 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.

If you do not use your arms or your legs for some time, they become weak; when you start using again, they slowly become strong again. Everybody knows this, and nobody would think of questioning the fact. ____1.____ When someone says that he has a good memory, he really means that he keeps his memory in practice by exercising it regularly, either consciously or unconsciously. When someone else says that his memory is poor, he really means that he does not give it enough opportunity to become strong. ____2.____ One of them exercises his arms and legs by playing tennis, while the other sits in a chair or a motor car all day.

If a friend complains that his arms are weak, we know that it is his own fault. __3.__, many of us think that his parents are to blame, or that he is just unlucky, and few of us realize that it is just as much his own fault as if it was his arms or legs that were weak. Not all of us can become extremely strong or extremely clever; but all of us can, if we have ordinary bodies and brains, improve our strength and our memory by the same means––practice.

Have you ever noticed that people who cannot read or write usually have better memories than those who can? ___4.____ Of course, because those who cannot read or write have to remember things:they cannot write them down in a little notebook.

I went to India for a 2-week vacation to visit my relatives. We stopped on a red light, and as always, there were a lot of activities outside the cars near the . People walked in, between the cars newspaper, water and a number of kids looked for a bit of charity from the car owners. It’s a familiar in most poor developing countries.

While we were for the red light to turn green, I noticed a man outside a couple of in front of ours trying to sell bottles of water. It’s unusual at first. He was a man in his 40s with relatively clothes. But he walked around in a strange way. He kind of his way around the spaces. He was blind.

Carrying a couple of water bottles on one hand, he got to the outside of our car. Out of , my mum decided to buy one water bottle. As she gave the man the money, the light turned green. The car behind sounded loudly and , trying to get ahead of traffic. Seeing this, my mum kindly told the man to the change. However, with his sense of touch, he quickly went through his shirt pocket and threw the money at my mum’s . It was the exact change. The cars behind us were really getting out of control, we decided to go on our way.

I broke down and even when I got home. Here’s a blind man, born in , trying to sell water bottles on the streets to make ends meet. He our sympathy. Life hasn’t been to him, yet he’s giving it his best shot. I think that is what is all about facing life bravely.

Most young people enjoy some forms of physical activities. It may be walking, cycling or swimming, or in winter, skating or skiing. It may be a game of some kind, football, hockey, golf, or tennis, it may be mountaineering.

Those who have a passion for climbing high and difficult mountains are often looked upon with astonishment. Why are men and women willing to suffer cold and hardship, and to take risks on high mountaineering? This astonishment is caused probably by the difference between mountaineering and other forms of activity to which men give their leisure.

Mountaineering is a sport and not a game. There are no man?made rules, as there are for such game as golf and football. There are, of course, rules of a different kind, which would be dangerous to ignore, but it is this freedom from man?made rules that makes mountaineering attractive to many people. Those who climb mountains are free to use their own methods.

If we compare mountaineering with other more familiar sports, we might think that one big difference is that mountaineering is not a “game”. We would be mistaken in this assumption. There are, it is true, no “matches” between “teams” of climbers, but when climbers are on a rock face linked by a rope on which their lives may depend, there is obviously teamwork.

The mountain climber knows that he may have to fight forces that are stronger and more powerful than man. He has to fight the forces of nature. His sport requires high mental and physical capacities.

A mountain climber continues to improve in skill year after year. A skier is probably past his prime by the age of thirty, and most international tennis champions are in their early twenties. But it is not unusual for a man of fifty or sixty to climb the highest mountains in the Alps. They may take more time than younger men, but they probably climb with more skill and less wasted effort, and they certainly experience enjoyment.

Throughout the world, clothing has many uses. It is used to provide protection from cold. It is also worn to prevent others from seeing specific parts of one’s body. However, the parts of the body that must be covered vary widely throughout the world. Some clothing is worn to provide supernatural protection. Wearing a lucky shirt to take an exam is calling for supernatural assistance.

People in all cultures use clothing and other forms of bodily decoration to communicate status(身份), intentions and other messages. In North America, we dress differently for business and various leisure activities. North American women usually are much more knowledgeable of little difference in messages communicated by clothes than men. At times, this leads to silly mistakes of understanding of female intentions on the part of men. Of course, clothing styles also are intended to communicate messages to members of the same gender(性别).

Long before we are near enough to talk to someone, their appearance tells their gender, age, economic class, and often even intentions. We begin to recognize the important cultural clues at an early age. The vocabulary of dress that we learn includes not only items of clothing but also hairstyles, jewelry, and other body decoration. In most cultures, however, the same style of dress communicates different messages depending on the age, gender, and physical appearance of the individual wearing it.

Putting on certain types of clothing can change your behavior and the behavior of others towards you. This can be the case with a doctor’s white lab coat, or an army uniform. Most uniforms are clearly symbolic so that they can rapidly and unmistakably communicate status. For instance, the strange hairstyle and clothing of the English “punks” are essential aspects of their uniforms.

There are many forms of body decoration other than clothes that are used around the world to send messages. These include body and hair paint, and even body deformation. When doctors put braces on teeth, they are actually doing the same thing – deforming or reforming a part of the body to make it more attractive.

Good student-teacher relationships result from the choices that are made even before school, and how those choices are carried out on a daily basis. Here are a few tips to make this process easier for both parties.

_1.__

For the teacher, this means that they need to look at each student from the perspective(角度) of what that student could learn, rather than what that student learned last week or last year. For the student, this means that they need to enter the classroom every day with the willingness to trust the teacher to help them understand. __2.__ Every school day there are new opportunities to learn new information or to understand subjects that might have been difficult in the past.

__3.__

This is not to say that you have to “buy” the affections(关爱) of the student or the teacher,but you can give the gift of a smile,the gift of attention in class,or the gift of eye contact. Giving this type of gift always helps to build strong relationships.

Demand the best.

__4.__ We can trust friends to keep us responsible and when developing good student-teacher relationships,the same principle of trust applies. Setting high expectations always pushes us to be our best,and when both the student and the teacher are pushing the other for more depth, more wisdom, more insight, etc,then both the student and the teacher will give more.

To develop a good student-teacher relationship,both the student and the teacher must be willing to decide to do these things daily. Each day,they must be willing to try again and work on the relationship. _5.__

A.Buy gifts for teachers.

B.Give gifts to one another.

C.Focus on the positive.

D.We can always learn a lot from our teachers.

E.Future learning is never limited by past experiences.

F. Good relationships are always founded on honesty and high expectations.

G.The most important thing is to trust the relationship to benefit each of the members.
