先介绍自己：My name is Allan,I am a reporter.
说明自己的意图：As we know,library is a public place of learning English.So we shouldn't break of the rules.And there are some rules.
分条写出纪律与规定,可运用first ,second,third,last,besides等词语连接.当你写完一条后,可以在其后说明规定这一条的原因.如：First,don't talk or laugh loudly.Because you will influence other people if you talk or laugh loudly.还可以说明这一条带来的好处,如第6条：Last,we should keep the library clean.So we will have a better learning environment.
最后结尾要有号召力：If we obey these rules,our library will be more and more clean and beautiful!或Let't create a better learning environment!
