don't forget to show your library card or i.d. card to the librarian before you go into the reading room, where you can read magazines or newspapers. if you find a good article and want to keep it, you can have it duplicated in the xerox room. besides, if you want to watch films or slides, you can ask the projectionist to play the videotape for you in the audio visual room, where you can also listen to language tapes and music tapes.
在你进入可以阅读杂志或报纸的阅览室前，别忘了给你的图书证或身份证图书管理员。如果你找到一篇好文章而且想要拥有它，你可以在影印室复制。此外，如果你想看电影或幻灯片，您可以叫放映员在视听的房间来为你播放录像，在那里你也可以听语言磁带和音乐磁带。
rules are made in public places to restrict people's behavior. and so is in the library. then how shall we obey the rules of the library?
firstly, we should keep in mind that the library is a place for reading, studying and the exchange of knowledge. so we are not supposed to talk loudly or eat things in the library.
secondly, we should just borrow the books that we need. some people like to borrow a lot of books that they don't even have enough time to finish them all in time. however, once you have taken those books away, the people who really need them may have to wait. it is surely a kind of waste.
at last, we should keep the books the way they are as much as we can because they are common properties. if we draw lines or circles on the books, it will make it harder for the next reader to read the book.
every library may have its own specific rules which, no matter what they may be, we have to obey because it is the basic principle for being a person.
