谁有英语从句的连词大全啊？

连词的功能：连词分为“并列连词”和“从属连词”两大类。并列句中的连词称为并列连词；复合句（包括定语从句、名词从句和状语从句）中的连词统称为从属连词。一般来讲，连接两个分句需要一个连词，多一个分句则需多一个连词。缺少连词或多用连词往往是句法错误的主要原因。汉语中没有连词概念，所以对连词功能的掌握是学好英语句子的关键。
状语从句连词：（一）时间状语从句：
常见的从属连词有：when, while, since, as, before, after, until, till, as soon as, by the time, every time等。
1、when的意思是“当…的时候”，由when引导的从句中的动词可以是延续性动词或非延续性动词。

英语中的从句有三种：名词从句、形容词从句（即定语从句）和副词从句（即状语从句）.
从句连接词可分为：陈述连词（that, if, whether等）、连接代词(what, who, whom, which, whose, whatever, whoever, whomever, whichever等)、连接副词（how, where, when, why,however, wherever, whenever等）；
引导定语从句的连词叫关系词,关系词又可分为关系代词和关系副词.
关于从句连接词的省略：
① 引导名词从句时：只有that引导宾语从句时才可省（且在口语中）,其余情况不能省,否则不是语法错误,就是意义不完整.
② 引导定语从句时：关系代词作宾语才可省,其余成分不省为好!e.g.
This is the book that/ which I bought yesterday.
(此句中that/which作宾语,可省)
＝This is the book I bought yesterday.
③ 引导状语从句时,连接词不能省,否则句意不完整!

英语中的从句分为三种：名词性从句、形容词性从句（即定语从句）和状语从句。名词性从句包括主语从句，宾语从句，同位语从句，形容词性从句是定语从句，状语从句包括时间状语从句，地点状语从句，让步状语从句，原因状语从句、条件状语从句、目的状语从句、结果状语从句等，这些在语法书上有详细的说明，我建议你买一本分章节，有习题，有解析的语法书，系统地看看，多看多练就好了，我的英语能力就是这样起来的
