     Sally was fourteen. She studied in a middle school. She liked dancing and singing and spent a lot of time

on them. But she hated maths and even decided to give it up. Her father was anxious (焦虑) about it.

     It was Sunday. Sally's father gave a call to his sister who taught maths in another school. He hoped she

would come and tell his daughter how to learn maths. The woman came and said,"You are a clever girl, Sally.

I' m sure you will soon learn maths well if you do your best"

     "I'm afraid I can't, Aunt," said Sally. "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

try different ways to practice doing maths problems until you work them out or at least understand them

better. Here is a maths problem. Please think it over and see if you can work it out."

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

     About an hour later Sally took the exercise book to her aunt and said, "I've tried several times and worked

out the problem at last!"

     "Well done!" her aunt looked at her answer and said happily, "Now you see, maths is not as difficult as

you thought."
