Rules are made in public places to restrict (限制) people's behaviour(行为). And so
is in the library. Then how shall we follow the rules of the library?
First, we should keep in mind that the library is a place for reading and studying. So
we mustn't talk loudly, run, eat or drink in the library. Second, we should keep the books
clean. And we should put the books in order after we finish reading them. Last but not
least, we mustn't litter in the library. We should put rubbish in the bin.
