答案
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 math and even decided
to give it up.Her father was anxious (焦虑) about it.
It was Sunday.
①Sally's father called to his sister who taught math in another school.
He hoped she
would come and tell his daughter how to learn math.The woman
came and said,"You are a clever girl,
Sally.I'm sure you will soon learn
math well if you do your best."
"I'm afraid I can't,Aunt," said Sally.
②"Girls can't be good at math."
"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 ③ ______ (do) math problems until you work them
out or at least
understand them better.Here is a math problem.④Please
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,math is not as difficult
as you thought."
