語言無論是何種語言都有正式與非正式之分。那麼，他們的區別是什麼?下面，我們一起來看一篇聽力原文。
You probable have noticed that people express similar ideas in different ways depending on the situation they are in. This is very natural. All languages have two general levels of usage — a fomal level and an informal level. English is no exception. The diffenrence in these two levels is the situation in which you use a particular level.
你或許注意到人們會用不同的方式表達類似的觀點，這取決於他們所處的環境。這種現象很自然。所有語言都有兩個普遍的使用層次——正式層面和非正式層面。英語也不例外。兩個層次的區別在於你使用語言的語境。
Formal language is the kind of language you find in textbooks, reference books and in business letters. You would also use formal English in compositions and essays that you write in school. Informal language is used in conversation with colleagues, family members and friends, and when we write personal notes of letters to close friends.
正式語言是在課本、參考書和商業信函中出現的語言。你也會在學校佈置的`作文的論文中使用正式語言。非正式語言是在與同事、家人和朋友交流時使用的，以及我們在寫個人筆記或給好朋友寫信時也會用到。
Formal language is different from informal language in several ways. First, formal language tends to be more polite. What we may find interesting is that it usually takes more words to be polite. For example, I might say to a friend or a family member "Close the door, please." But to a stranger, I probably would say, "Would you mind closing the door?"
正式語言和非正式語言在很多方面有所不同。首先，正式語言顯得更禮貌。我們發現的有趣現象是通常要想追求禮貌，我們必須多說些話。例如，我或許會對我的朋友和家人說“請關門。”但是，對於一位陌生人，我可能會說“你介意把門關上嗎?”
Another difference between formal and informal language is some of the vocabulary. There are bound to be some words and phrases that belong in formal language and others that are informal. Let's say that I really like soccer. If I am talking to my friend, I might say. "I am just crazy about soccer." But if I were talking to my boss, I would probably say, "I really enjoy soccer."
正式語言和非正式語言的另一處不同在於部分詞彙。某些詞彙與詞組屬於正式語言，而有些是非正式的。我們說真的喜歡足球時，如果和我的朋友交流，我或許會說：“我爲足球瘋狂。”如果對我的老闆，或許會說：“我很欣賞足球。”
