谁能给我说一下英语从句连接词怎么用?
我总是搞不清什么时候加什么时候不加

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!
