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.

Many teenagers feel that the most important people in their lives are their friends. They believe that their family members, especially their parents, don’t know them as well as their friends do. In large families, it is often for brothers and sisters to fight with each other and then they can only go to their friends for advice. It is very important for teenagers to have one good friend or many friends. Even when they are not with their friends, they usually spend a lot of time talking among themselves on the phone. This communication is very important in children’s growing up, because friends can discuss something difficult to say to their family members.

However, parents often try to choose their children’s friends for them. Some parents may even stop their children from meeting their good friends. The question of “choice” is an interesting one. Have you ever thought of the following questions?

A few years ago, I took a sightseeing trip to Washington D.C. I saw many of our nation’s treasures, and I also saw a lot of unfortunate people like beggars and homeless folks in the streets.

Standing outside the Ronald Reagan Center, I heard a voice say, “Can you help me?” When I turned around, I saw an elderly blind woman with her hand extended(伸出). In a natural reaction, I reached into my pocket, pulled out all of my loose change and placed it in her hand. I didn’t even look at her. I was annoyed at being bothered by a beggar.

But the blind woman smiled and said, “I don’t want your money. I just need help finding the post office.”

Immediately, I realized what I had done. I acted with prejudice(偏见)—I judged another person simply for what I thought she was.

The thing I had forgotten about myself is that I am an immigrant. I left Honduras and arrived in America at the age of 15. Through the years, I have been a dishwasher, cashier, mechanic and pizza delivery driver among many other jobs, and finally I became a network engineer.

In my own life, I have experienced many open acts of prejudice. I remember a time, at age 17— I was a busboy, and I heard a father tell his little boy that if he did not do well at school, he would end up like me.

But now, living in my American middle-class lifestyle, it is too easy to forget my past, to forget who I am and where I have been, and to lose sight of where I want to be going. That blind woman on the street of Washington D.C. cured me of my blindness. She reminded me to always keep my eyes and heart open.

1.When the author came to America at first ______.

A. he usually did some work with a little payment.

B. he used to beg for some money on the street.

C. he lived a comfortable life as a network engineer.

2.According to the passage, what did the author regret?

A. That he gave all his change to the blind woman.

B. The way he treated the blind woman.

C. That he came to Washington D.C. for a visit.

D. That he didn’t tell the woman the way to the post office.

3.The father mentioned in the passage wanted ______.

A. to encourage his son to make a living by himself

B. his son to become a busboy in the future

C. his son to work harder at school

D. to remind his son to depend on himself at school

4.We can infer all of the following statements from the passage EXCEPT ______.

A. He disliked being bothered by beggars.

B. He was delighted to give away his money to beggars.

C. He once suffered a lot.

D. The blind woman didn’t beg for money at that time.

5.What does the author want to tell us through this story?

B. Money is the root of all evils.

C. An easy life makes a person forgetful.
