| Jane Scott is fourteen years old and last year she began to study in a middle school. She likes dancing and singing and spends a lot of time on them. (1)_____________. She thinks it difficult to learn. Once she failed the math exam, and now she decides to give it up. (2)_____________. It was Sunday. Mr. Scott gave a call to his sister. She teaches math in another school. He hoped she would come and tell his daughter how to learn math. The woman came quickly and said, "You're a clever girl, Jane. (3)______________." "I'm afraid I can't, Aunt," said Jane. "I am not interested in math at all." "I don't think so," said the woman. "I was good at it when I was a girl. You can do more exercises and practice a math problem again until you make it. Well, here's a math problem. Think it over and practice it again and again, then you will work it out." "OK," said the girl, "Let me have a try." About an hour later Jane took the exercise book to her aunt and said," (4)____________." "Well done!" her aunt said happily, "What answer did you get?"
