    Jane Scott is fourteen and the year before last she began to study in a middle schoo1. She likes dancing and

singing and spending a lot of time on them. But she hates (不喜欢) maths and does not work hard at it. 

    She thinks it difficult to learn. She falls behind her Classmates and once failed the maths exam. She decided to

drop (放弃) it. Her father is angry with her when he knows about it. 

    It was Sunday. Mr Scott gave a call to his sister who teaches maths in another schoo1. He hoped she would

come and tell his daughter how to learn maths. The woman came quickly and said, "You're a clever girl, Jane.

I'm sure you'll soon do well in maths if you work hard at it." 

    "I'm afraid I can't, Aunt," said Jane. "Girls can't be good at maths."

    "I don't think so." said the woman. "I was good at it when I was a girl. You must do more exercises and

practice a maths problem again until you master (掌握) it. Remember:Practice makes perfect (熟能生巧). 

    Well, it's a maths problem. Think about it and practice it again and again and you'll work it out."

    "OK." said the girl, "Let me try." 

    About an hour later Jane took the exercise book to her aunt and said, "I've done the problem ten times."

    "Well done!" Her aunt said happily. "What result did you get?"

    "Ten answers."

A big company wanted a clerk, so John went there. In the interview the director asked him a question.

“Who paid for your school?”

“My mother paid for it by washing clothes.”

Hearing this, the director asked John to show his hands. John showed a pair of hands that were perfect. The director said,“When you go back today, go and clean your mother’s hands, and then see me tomorrow morning.”

When John went back, he happily asked his mother to let him clean her hands. However, his tears fell as he cleaned his mother’s hands.
