連接詞的作用不容忽視，詞雖簡單常見，但是卻串聯(lián)起了一個個句子，讓句與句之間的關系不同，或因果相連，或意思更進一步……
下面我們從從句的角度了解下連接詞：
1．名詞性從句
關系代詞：what,who,whom,which
關系連詞：that,when,where,how
2．形容性從句
關系代詞：that,who,whom,whose, which,as
關系連詞：where,when,why,how
3．副詞性從句
狀語從句類型 常用連接詞 特殊連接詞
時間狀語從句 when,while,as,before,since,till,
until, as soon as ①一些時間名詞：the moment, the instant, the minute, the day, next time, every time
②一些副詞：instantly，immediately，directly
③固定搭配的連詞：no sooner...than, hardly...when,scarcely...when

條件狀語從句 if, unless suppose, supposing, providing, provided(特別關注：supposed, provide不用作條件從句的連詞)， on condition that, so long as, as long as
讓步狀語從句 although, though, even though, even if while(一般用在句首)， as（用于倒裝結構），whatever, whoever, whichever, however, whenever, wherever, whether...or..., as+adj.+as+主謂結構（句首）
比較狀語從句 as, than the more...,the more...;just as..., so...;A is to B what/as C is to D; no more...than; not A so much as B/not so much A as B
