I work in a school library. There1 many kinds of books in it. You can do some reading or borrow books from it. But it has some2. You must obey them. When you are reading in the library, you have to be quiet. You shouldn't talk loudly3make any noise. You can't take your bags into the library.4 or drink in the library. You can borrow books from the library, but you can't lend (借出) them to others. You have to take good care of them and give them back on time. If the library books are5, you have to pay for them.
