Do you believe that we can have an important influence on anyone we meet? The right words at just the right time could 1someone's life.

    When I was 3 years old, my parents discovered I was2. After asking many doctors and parents of other deaf children, they decided not to put me in a special school. Although I seemed outgoing, my self-esteem（自尊心）was quite low. On my first day at school, the other kids3 me because of my hearing aid andthe way I talked. I was hurt deeply and I saw myself as a(n)4kid.

    Mrs. Green, my5,changed all of that with a simple three-word phrase. One morning, she asked the class a question. Sitting at my desk silently, I 6 herlips（嘴唇）and raised my hand right away. She called on mein front of the blackboard. I took a deep breath and7 answered Mrs. Green's question.

    I will8forget what happened next. Mrs. Green pointed directly at me. With sparkling （闪光的）eyes and a big smile she cried:         "That's right, Ben!"

    For the first time in my young life, my confidence（自信）rose. At that moment, I decided that no matter how many9 I may face, I can overcome（克服）them. Thanks to those three 10 words, my whole life changed from that moment.

    Working in Africa, one day we went to an orphanage (孤儿院). There we met a lovely little girl named Tanzile. I gave her a sweet I brought. “She 1 one more, doctor,” said the nurse. I said “Of course.” and gave her 2.

    Before we left, we went to say 3 to Tanzile. She was holding the sweets I had given her.

    I said to the nurse, “This little girl is clever. She has taken two sweets for herself.”4 after the nurse asked her some questions, we learned the 5 about Tanzile.

    Tanzile was 7 then. Two years before, her mom and dad had both died of AIDS. Her baby sister was taken away from her. From then on, whenever she  6 anything from people, including food, she refused to accept unless they gave her two — one for her and one for her 7.

    In fact, in her room, we found quite a few old things which she  8 38   to give her sister one day.

    Later that day, I was 9 to find that this was not an isolated (个别的) story. There were many orphans just like Tanzile. With a lot of things in their rooms, they 10 for their brothers and sisters who they hadn't seen for so long.

    People sometimes think African children are different from our kids. They think that the children there don't feel pain or sadness or love. But that is not true. Their pain is deep. And so is their love.

    One day, several young people went for a picnic. They walked in the open air with 1.

    As soon as they came to a river, they 2 by the clear and calm water. They played with cool water excitedly. Suddenly, a lovely 3 passed by Tom. He tried to catch it, 4 the fish was just swimming a few feet ahead of him. He ran 5 it, hoping to catch it.

    Gradually, Tom came to the water with waist deep. He felt 6, so he wanted to jump out of the water. 7 up and down in the water, he went farther and farther away from the bank. Just at that time, Barry saw this, he offered 8 help to Tom at once. Tom saw someone 9 to him, he caught the person 10 was close to him. Unfortunately, Barry was dragged into the water. The two struggled in the water 11.  Amy, on the bank, noticed that, and she 12 others near the bank.

    Hearing their cries, two farmers near the river took a long rope there. They threw one end of the rope to 13 of them in the water. Together, all the people on the bank pulled 14 end.

    Finally, the two boys were saved!

    The experience has told us 15 we should do something to help others correctly.

    Mary was ill, so she went to see 1 .

    "Doctor, I'm not feeling 2," said Mary. "Every time I do my homework, I feel 3 . If I go to school on foot, I have to sit down and 4 for a few times."
