阅读短文，判断正误 Helen was seven years old, and one day one of her teeth began hurting. She cried in her class at school. Her teacher said kindly, “What's the matter, Helen?” “One of my teeth hurts,” answered Helen.“Tell your mother about it," said the teacher,“and then go and see the dentist.”
That afternoon Helen told her mother about her teeth, and her mother took her to the dentist later. The dentist examined the tooth and then he said to Helen,“It' s very bad. I'm going to pull it out, and then you are going to get a new tooth. It will be as nice as the others next year.” He pulled the tooth out.
The next day Helen's teacher asked her about the tooth. She said to her,“Does it still hurt, Helen?”“I don't know. You'd better(最好) ask the dentist.” Helen answered.“Why?”the teacher said.“Because the dentist has got it," Helen answered.
