There was a small Kangaroo(大袋鼠)who was bad in school. He put thumbtacks(图钉)on the teacher’s chair. He threw spitballs(唾沫弄湿的纸团)across the classroom. He set off firecrackers(爆竹)in the lavatory(厕所)and spread glue(撒胶水)on the doorknobs(门扶手).
　　“Your behavior(行为,举止)is impossible!”said the school principal(校长). I am going to tell your parents what a problem you are!
　　The principal went to visit Mr and Mrs Kangaroo. He sat down in a living-room chair.
　　“Ouch!”cried the principal. “There is a thumbtack in this chair!”
　　“Yes, I know,”said Mr Kangaroo.“I enjoy putting thumbtacks in chairs.”
　　A spitball hit the principal on his nose.
　　“Forgive me,”said Mrs Kangaroo,“but I can never resist(忍住)throwing those things.”
　　There was a loud booming(发出隆隆声)sound from the bathroom.
　　“Keep calm(安静),”said Mr Kangaroo to the principal.“The firecrackers that we keep in the medicine chest have just exploded (爆炸). We love the noise.”
　　The principal rushed for the front door. In an instant(立即) he was stuck(粘住)to the doorknob.
　　“Pull hard,”said Mrs Kangaroo.“There are little globs of glue on all of our doorknobs.”
　　The principal pulled himself free. He dashed out of the house and ran off down the street.
　　“Such a nice person,”said Mr Kangaroo.“I wonder why he left so quickly.”
　　“No doubt he had another appointment,”said Mrs Kangaroo.“Never mind, supper is ready.”
　　Mr and Mrs Kangaroo and their son enjoyed their evening meal. After the dessert(甜点),they all threw spitballs at each other across the dining-room table.
　　A child’s conduct(行为)will reflect(反映)the ways of his parents.
