Little Mary is a good girl. She began to go to school last year and now she's in Grade
2. Her home is not far from the school, but she is often late for class because she watches TV and listens to the music in the evening and goes to bed very late. So she can't get up on time in the morning. This term Mr. White, Mary's uncle, works in her school. He teaches Grade 2 history. He is very strict, of course, with Mary, too. He often tells Mary to keep the school rules and come to school on time. Today Mary gets up late again. When she goes to school, it is 8:
15. Her uncle is waiting for(等待) her at the school gate. "You're ten minutes late for the first class. " Mr. White is very unhappy. "Why are you often late for class?" "Every time when I get near school, I always see a sign(标志). It says "SCHOOL—GO SLOW!(慢行)"said Mary.
