Families and schools have some rules, Some students think they are important(重要的) and always obey them, but others don't. Mary and her cousin Jane are American girls. They are good children in the same school.
They think obeying the rules is very important. One day Mary gets an idea. She wants to make a book of rules. She says." I think the book can help Jane, our brothers, sisters and me to be good children. If he or she doesn't obey the rules, he or she has to sit at the door for five minutes."
The two girls begin writing the book of rules. There are some school rules like "Do your homework, Don' t be late for school "There are also some interesting rules in it, such as, "No eating other people's food "and "Don't cry."
Both girls like the book very much. Their brothers and sisters think it is very interesting and they often do as (像) it says. Their classmates want to read it, too. Their teachers and parents want to publish(出版)it for them.
