informative，英语语言学的六大功能？
1．指示功能（ referential function）
指示功能是指语言对现实世界和虚拟世界中的各种现象进行描述的功能，又称为外延功能（ extension
function）或认知功能，如事物的所指关系，英语中的指示代词this, that, these, those 的所指，都是语言的指示功能。
2．指使功能（ directive function)
当我们使用语言来指使某人做某事时，此时语言就发挥了指使功能。英语祈使句就是典型的具有指使功能的话语。例如：“ Close the door, please．”“Don't move．”
3. 信息功能（ informative function)
信息功能是语言最主要的功能之一。信息功能是语言传递、表达信息的功能，通常是以陈述句表述。信息功能具有辨别性，或真或假。例如，“ He went to NewYork yesterday with his sister．”
4．应酬功能（ phatic function)
应酬功能是指人们使用语言是为了建立和维持社会接触而进行的日常寒喧，而不是为了交流信息。例如，打招呼（Hi/Hello）、谈论天气（ A nice day，isn't it？）、告别（ See you soon．）、问候语（ How are you doing？）等。
5. 元语言功（metalinguisticfunction）
元语言功能是指用语言去解释语言的功能。元语言指的是用来分析和描述另一种语言（被观察的语言或目的语）的语言或一套符号，如用来解释另一个词的词或外语教学中的本族语
6. 疑问功能（ interrogative function）
疑问功能是指语言可用来向人提出问题以获得信息。凡是期待回答的问句都具有疑问功能，如“What's your comment？”。
7．表达功能（ expressive function)
表达功能是指人们使用语言表达对某事物的感情或态度。在执行表达功能时，语言用来评价、赞扬说话人的态度。最常见的例子就是感叹句，例如：“I'm extremely sorry about that！”

书信的结尾致意要留意,弄清大家的关系才选择用词。
有时在we, I, and you之间选择是很烦的事-- 如果是公司代表联络生意之类,可以用: We will reimburse you for these legal expenses. Sinopec will reimburse you for these legal expenses. 如果单纯说你自己,可以用: I found the brochure very informative.
