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 ℃, 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.
The biggest difficulty in operating on the damaged brain is that____ .

A.the time is too short for doctors
B.the patients are often too nervous

The year 2009 is the Year of Ox. The ox is a representative of the fanning culture of China. In the farming economy (经济), oxen are the major animals pulling plows (犁).
Of course, the good of oxen is not limited to plowing. In fact, they are seen as “boats on land” for their ability to carry loads. Besides, the whole body of an ox is full of treasures. Their meat and milk are food full of nutrition, and their skin can be used to make clothes and shoes. With all these qualities, oxen are regarded as generous creatures.
In the past, oxen played an important role in the spiritual life of the Chinese. Even today, oxen still play a special part in some folk activities. For example, some people who1ive in southwest China will cook cattle bone soup and share it among family members when holding the ceremony for children who reach 13. They believe that the cattle bone soup represents the blood relationship among family members. In order to express their love for oxen, people in some other areas will run to shake off diseases on the 16th day of the first month by the lunar calendar (农历), and during their run they will take their oxen along, which indicates they regard the creature as human.
Because of the contribution of oxen in their lives, the Chinese people are very grateful to the animal. In addition, the use of oxen in ceremonies and the thanks people owe to oxen help to develop various traditional customs, which becomes an important part of the folk culture of the Chinese nation.

For a long time being happy was considered something that just happened, and there was nothing special to do about it. Now we know that getting along with ourselves and with other people is something that we can work at. It is possible to act in such a way that other people will like us better. One way is being unselfish, not wanting everything our own way or demanding the best share of everything, including the attention of our friends. Another way is to look for good points, not bad ones in other people, it is surprising how successful this treasure hunt can be.
You don't have to be spineless(懦弱)in order to be popular. In fact,you will be liked and respected if you are not afraid to stand up for your rights. But do it politely and pleasantly. Being friendly and polite to your own group, to older people, to strangers and especially to those who do not look important or do not interest you is one way to develop a good character.
You can not expect to be perfect, and so you must learn not to be too unhappy when you make a mistake. Everyone makes mistakes, and no one is to be blamed unless he refuses to learn from them. Many young people become discouraged when they recognize in themselves qualities that they do not like--selfishness, laziness and other unpleasant qualities. Just remember that we all have some of these faults and have to fight against them.
At the same time, it is important to remember that, while you are probably no worse than others, chances are you are not much better, either. The surest way to be happy is to think yourself above other people.
When something is wrong, it is good sense to try to make it right. Perhaps you don't like a teacher or a classmate. Try to see why, and look at yourself, too, to be sure that you are not doing something to make that person dislike you. In time, things may turn out all right if you just keep trying to be pleasant and polite. If things do not turn out all right, then you will simply have to learn to get along the best you can with the situation, without thinking too much about it. Worrying never helps in a situation you can't change.
41. One of the two ways the author suggested for us to get along well with others is______
A. to draw attention of our friend
B. to demand the best share of everything
C. to look for treasure in order to be successful
D. to pay more attention to other people's good points

As the pace of life continues to increase, we are fast losing the art of relaxation. Once you are in the habit of rushing through life, being on the go from morning till night, it is hard to slow down. But relaxation is essential for a healthy mind and body.
Stress is a natural part of everyday life and there is no way to avoid it. In fact, it is not the bad thing it is often supposed to be. A certain amount of stress is vital to provide motivation and give purpose to life. It is only when the stress gets out of control that it can lead to poor performance and ill health.
The amount of stress a person can bear depends very much on the individual. Some people are not afraid of stress, and such characters are obviously prime material for managerial (经理的)responsibilities, others lose heart at the first sign of unusual difficulties. When exposed to stress, in whatever form, we react both chemically and physically. In fact we make choice between “flight or fight” and in more primitive days the choices made the difference between life or death. The crises we meet today are unlikely to be so extreme, but however little the stress, it involves the same response. It is when such a reaction lasts long, through continued exposure to stress, that health becomes endangered. Since we can’t remove stress from our lives (it would be unwise to do so even if we could), we need to find ways to deal with it.
36. People are finding less and less time for relaxing themselves because _______.
A. they regard working as their greatest enjoyment
B. they believe that work is superior to relaxation
C. they are traveling fast all the time
D. they are becoming busier with their work than ever before
37. According to the author, the most important character for a good manager is his ______.
A. strong will to hold out (顶住)stress
B. knowing the art of relaxation
C. high sense of responsibility
D. having control over performance
38. Which of the following statements is TRUE, according to the passage?
A. We can find quite a few ways to avoid stress.
B. Stress is always harmful to people’s health
C. It's easy to change the habit of keeping oneself busy with work.
D. Different people can bear different amount of stress.
39. In the last sentence of the passage, “do so” refers to _____.
A. “expose ourselves to stress”
B. “find ways to deal with stress”
C. “remove stress from our lives”
D. “establish links between diseases and stress”
40. According to the author, the right attitude toward stress is _____.
A. to avoid it B. to try to cope(应付) with it
C. to regard it as a vital motivation D. to find some relaxation

I’ve loved my mother’s desk since I was just tall enough to see above the top of it as Mother sat doing letters. Standing by her chair, looking at the ink bottle, pens, and white paper, I decided that the act of writing must be the most wonderful thing in the world.
Years later, during her final illness, Mother kept different things for my sister and brother. “But the desk”, he said, “is for Elizabeth” 。
I never saw her angry, never saw her cry. I knew she loved me, she showed it in action. But as a young girl, I wanted heart-to-heart talks between mother and daughter.
They never happened. And a gulf opened between us. I was “too emotional”. But she lived “on the surface”.
As years passed and I had my own family. I loved my mother and thanked her for our happy family. I wrote to her in careful words and asked her to let me know in any way she chose that she did forgive me.
I posted the letter and waited for her answer. None came.
My hope turned to disappointment, the little interest, finally, peace — it seemed that nothing happened. I couldn’t be sure that the letter had even got to Mother. I only knew that I had written it, and I could stop trying to make her into someone she was not.
Now the present of her desk told me, as she’d never been able to, that she was pleased that writing was my chosen work, I cleaned the desk carefully and found some papers inside — a photo of my father and a one-page letter, folded and refolded many times.
Give me an answer, my desk, in any way you choose, Mother, you always chose the act that speaks louder than words.
