    One day a little boy dialed a telephone number and started to speak and he put part of his hand over the phone at the same time. He wanted to change the tone (音色，语调) of his voice. While all this was happening, a man who was working nearby, watched carefully and listened with great interest to the conversation that followed:

    “Lady, can you give me the job of cutting your lawn (草坪)?”

    “I already have someone to cut my lawn,” answered the woman at the other end of the phone.

    “Lady, I will cut your lawn for half the price of the person who cuts your lawn now.” “I'm very satisfied with the person who is cutting my lawn.”

    The boy said, “Lady, I'll even sweep the floor and the stairs of your house for free.”

    “No, thank you.”

    With a smile on his face, the young boy thanked the lady and hung up the phone. The man then walked over to the boy and said: “Son, I like your attitude（态度）. I'd like to offer you a job.”

    “No, thanks,” said the boy.

    “But you're looking for a job, aren't you?”

    “No, sir,” answered the boy. “I was just checking on my performance at the job I already have. I am the one who cuts that lady's lawn!”

    Pablo Casals was a great cello（大提琴） player and music writer. He was born in Catalonia, Spain. He first heard the cello played when he was 11.Generally, he felling love with the instrument. So, he went to school at the Escuela Municipal de Musica. He focused on his studies and got high grades. When he finished school, he played the cello in the queen's palace. He became more and more famous. Soon, he began to play for audiences worldwide.

    After the events of the Spanish Civil War, Casals left Spain. He refused to go back. He went to live in Puerto Roco. He continued his work as a teacher. Healso recorded many albums（相册）. At the age of 80 he married his third and final wife, Marta Montanez.

    Casals died in 1973.The king of Spain had enjoyed Casals' music very much. He ordered a postage stamp to be made. It showed a picture of the cellist.

    One pleasant evening, I was holding Grandpa's hand and taking a walk in the park. "Where are the peanuts? Give me now!" He suddenly said. How I wished I had some with me! "William, the monkeys are taking long to come out today. Wait till they smell the peanuts." I knew he was lost in one of his memories again. I remembered the stories he told me of how he fed the monkeys when he was a kid. Then, he saw the goldfish! He acted as if he was seeing them for the first time.

    Poor Grandpa! He fell ill with Alzheimer's disease (阿尔茨海默症) last year. The doctor said it was a progressive brain disorder which could destroy (破坏) a person's memory. The patient might also not be able to make reasonable judgments (判断). The saddening part was that it was a lifelong disease. But when my parents invited him to stay with us, he refused and said he liked living alone. One day, he forgot to turn off the fire after cooking porridge. Luckily, one of the neighbors came to help him before the fire could spread.

    It was then that my parents brought Grandpa to live with us. Often, he would forget my name and ask me who I was and what I was doing in his house. Each time I would answer softly, "It's me, Ray, Grandpa!" Even if he had forgotten who I was, he would always be my beloved grandfather.

    Mr. Chen was puzzled（闲惑的）and a little suspicious（怀疑的）. He sat in the office and studied a letter apparently（看似）from Mrs. Wang, the mother of one of the pupils in his class. There was something about it which worried him.

    "I don't understand," he said to himself. He shook his head as he circled four mistakes in the letter. "Mrs. Wang is an educated woman. She wouldn't make mistakes like these even if she did write the letter in a hurry. "Mr. Chen took out his class register(名册)and said to himself, "Yesterday was Thursday. Let me see. Ah, yes. I thought so. David was absent on Thursday last week and the week before. Hm. Why is he so often absent on Thursdays? Was he really ill yesterday? Could it be a coincidence(巧合)?”

    Mr. Chen stared at the register as if the answers to his questions were hidden in it somewhere. Then he took out a copy of the timetable(课程表)for his class.

    "I wonder." he told to himself. "I wonder if his absence has anything to do with one of these lessons."

    Mr. Chen looked at the subjects for Thursday: Mathematics, English, P. E. He thought about P. E. He knew that the pupils had P. E. twice a week: once on Monday, when they usually played games on the school field, and once on Thursday, when they did exercises in the gym.

    Mr. Chen glanced round the office to find Mr. Long, the rather strict P. E. teacher, but he was not there.

    "I'd better have a chat with Long and David, "Mr. Chen thought.

The bell rang. "I can't do anything right now," Mr. Chen thought. "It's time to go to Class 2. I'll do it later on."

    Mr. Chen picked up his books and walked off to teach Class 2.

Later, on Friday, Mr. Chen spoke to Mr. Long, the P. E. teacher. Mr. Long agreed that it seemed strange for David to be absent so often on gym days. They thought about it for a while.

    "David is a good athlete(运动员)," Mr. Long finally said, "but he's afraid of heights. I was hard on him once because he wouldn't climb more than a couple of meters up the rope. Do you think that's why he's been absent recently?"

    "Yes, I think so," Mr. Chen said. "I'm going to talk to him this afternoon before he goes home."

    "Well, I've got a suggestion to make," said Mr. Long. "If he's scared of heights, he'd better come and see me after school. Quite a few people suffer from (遭受) vertigo. I'll be glad to help him."

    “That's very kind of you," said Mr. Chen. "I'll get him to come and see you on Monday or Tuesday."
