Little Peter is a boy of nine. He began to
go to school when he was six, and now he is in Grade Three. He lives not far
from the school, but he is often late for class. He likes watching TV in the evening
and goes to bed late, so he can't get up on time in the morning.
This term, Mrs. Black, Peter's aunt,
teaches music in Peter's school. She is strict (严格的)
with Peter and often tells the boy to obey the school rules and come to school
on time. Yesterday morning, Peter got up late. When he hurried to school, it
was a quarter past eight. His aunt was waiting for him at the school gate.
"You are ten minutes late for the
first class, Peter," Mrs. Black said angrily. "Why are you often late
for class?" "Every time, when I get to the street corner, I always
see a guidepost (路标). It says 'SCHOOL—GO
SLOWLY'!".
