阅读理解: 根据下面短文的内容判断下列句子的正误, 正确的用"T"表示, 错误的用"F"表示. 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(焦虑的)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 practise doing maths problems until you think it over and see it 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!"
