Little Mary is a good girl. She's in Grade 2. Her home is not far from school,but she is often late for class because she likes watching TV 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 with the students,of course,with Mary,too. He often tells Mary to follow the school rules and come to school on time.
Today Mary gets up late again. When she gets to school,it is 8:15. Her uncle waits for her at the school gate. "You are ten minutes late for the first class. " Mr White says angrily. "Why are you often late for class?"
"Every time when I get to the street corner,I always see a sign(标志)It says ‘SCHOOL﹣GO SLOW! (慢行)'"says Mary.
