Mark is a good boy,but he is not very clean.His face and hands always very dirty.

　　One day,Mark goes to school.His teacher looks at him and says:"Mark,I know what you eat today.""What?"Mark asks. "Eggs.your face and your mouth tell me that."

　　"No."Mark says,"not today,but the day before yesterday."

　　翻译：马克是个好男孩，但他不是很干净。他的手和脸总是很脏。

　　一天，马克去学校。他的老师看着他，说：“我知道你今天早上吃了什么。”“什么?”马克问道。“鸡蛋。你的脸和嘴告诉了我。”“不，”马克说，“不是今天，是前天。”
