A: Hi, madam. I came to return these books. Here you are. B: Oh, I'm afraid that most of them have been over due for several days... Oh, this one has been over due for two months! A: Oh my gosh! I didn't expect that. I should have applied for an extension. B: You'd better make a reading list. Don't just take away a stack of books from the bookshelf mindlessly. You should ask the librarian for help. A: Well... now I want Les Miserables. B: You need to reserve it, sir. Now show me your library card.本回答被网友采纳
