A small cloud moves slowly through the air in a hospital operating room (手术室).In the room a patient with cancer(癌症),lies on a table.The cloud is all around the patient,covering her body and filling her lungs(肺).The cloud is not smoke.It is made of millions of nano﹣robots(纳米机器人).These tiny robots move from cell (细胞) to cell in the patient's body,killing the cancer.

    Fighting cancer with nano﹣robots is only an idea today,but scientists say that it could be possible in the future.Using nano﹣robots for good purposes such as fighting the illness or repairing the environment may be the way to many of today's problems.

    However,nano﹣robots could be a dangerous risk as well.Because nano﹣robots are so tiny,they will have to work in large teams of many thousands to many millions.For this reason,nano﹣robots will have to be programmed(被编程)to build themselves.Scientists will not have the ability to build millions of nano﹣robots one by one.

    This ability to re﹣produce is making some scientists worried.What will happen if something goes wrong in the programming?Quite a lot of crazy nano﹣robots would be far worse than any illness.Some people think that if they get out of control,nano﹣robots could make the Earth gone.

    What should be done?Should we continue researching nano﹣robots or should we search for other methods?This is one of the many difficult decisions that we have to make in the future.

Once I thought love meant flowers, gifts and sweet kisses (吻). So, I really doubt (怀疑) whether (是否) there is love between my parents. Every day they are very busy trying to make money to pay the schooling for me. They don’t act in the romantic ways that I read in books or I see on TV, and sending flowers to each other on Valentine’s Day is even impossible.
One day, my mother was sewing a quilt (被子). I asked her if there was love between them. She stopped her work and looked up with surprise. Then she bowed (弯下) her head and continued sewing the quilt. I was very worried because I thought I hurt her. But after a few minutes she said, “Look at this thread (线). Sometimes it appears, but most of the time it disappears in the quilt. If life is a quilt, then love should be a thread. It can hardly (几乎不) be seen anywhere or anytime, but it’s really there, and makes the quilt long-lasting.” I listened carefully but I couldn’t understand her until the next spring.
My mother suddenly got sick seriously and had to stay in the hospital for a one-month treatment. Every morning and dusk (黄昏) after she returned from the hospital, my father helped my mother walk slowly on the country road. There were many beautiful flowers, green grass and trees, and the sun gently shone them through the leaves. All of these made up the most beautiful picture in the world. Reading their eyes, I knew they loved each other deeply. From this experience, I realized that love was just a thread in the quilt of our life. Love is inside, making life strong and warm.

One day, many years ago, when I was working as a psychologist(心理学家) in England, David was brought into my office. His face was pale(苍白的)and he looked at his own feet.
David lost his father when he was two years old and lived with his mother and grandfather ever since. But the year before he turned 13, his grandfather died and his mother was killed in a car accident. His teacher told me that he refused to talk to others from then on.
How could I help him?
David didn't say a word. As he was leaving, I put my hand on his shoulder."Come back next week if you like. "I said.
He came and I suggested we play a game of chess. He agreed. After that we played chess every Wednesday afternoon--in complete silence. Usually, he arrived earlier than agreed. It seemed that he liked to be with me. But why didn't he ever look at me?
"Perhaps he simply needs someone to share his pain (痛苦)with," I thought.
Months later, when I was looking at his head, he suddenly looked up at me. "It's your turn," he said. After that day, David started talking. He finally got friends in school and he even joined a bicycle club. He wrote to me a few times. Now he had re ally started to live his life.
Maybe I gave David something. But I learned a lot from him. I learned how time makes it possible to get over what seems to be painful. David showed me how to help people like him. All they need is a shoulder to cry on, a friendly touch and an ear that listens.

It was the end-of-year party. I had asked my mother to make us cookies. Mom’s chocolate chips were the best.
But two o’clock passed, and there was no sign of her. Most of the other mothers had come and gone, dropping off their cakes and chips. The party went on, but I wouldn’t leave the window. The three o’clock bell soon took me away from my thoughts(思绪). I took my bag and walked out for home.
The house was empty when I arrived. My heart was filled with anger(气愤). For the first time in my life, my mother had let me down. I was lying on my bed when I heard her coming. “Robbie,” she called out. “Where are you?” She was looking for me from room to room, but I kept silent.
When she came into my room, I didn’t move, “I’m so sorry,” she said. “I got busy and forgot.” She began to laugh. I couldn’t believe it. I turned over and found that she wasn’t laughing but crying. “I’m so sorry. I let my boy down.” she cried like a little girl. I had never seen my mother cry.
“It’s OK, Mom,” I said, “We didn’t need those cookies. There was plenty of food to eat. Don’t cry. It’s all right.” We held each other in a long hug(拥抱).

You may know the English letters A, B and C. But do you know there are people called ABC? You may like eating bananas. But do you know there is such a thing a “banana person”? How strange! Are these people from “another earth”? No, they are just Chinese people like you and me.
ABC means American-born Chinese. An ABC is a Chinese, but was born in the United States. Sometimes, people call an ABC a “banana person”. A banana is yellow outside and white inside. So, when a person is a banana, he or she is white inside-thinking like a Westerner and yellow outside-looking like a Chinese.
Do you know why? Usually, ABCs know little about China or the Chinese language. Some of them don’t speak Chinese. Also, they are not interested in Chinese politics.
But if ABCs can not speak Chinese, can we still call them Chinese people? Yes, of course. They are Chinese. They are overseas Chinese. These people may be citizens (公民) of another country like the US, Canada or Singapore. But they have Chinese blood. Their parents, grandparents or even great-grandparents were from China. They all have black eyes and black hair. But they are not Chinese citizens. They are not people of the People’s Republic of China. For example, we all know the famous scientist, C.N.Yang(杨振宁). He got the Nobel Prize for Physics in 1957. Chinese people love him. But he is an American citizen.
“ABC” in this passage means “”.

A.three English letters B.a kind of banana
C.Chinese born in America D.Americans born in China
