英语八大从句类型与用法总结举例如下:
一、定语从句:
在复合句中, 修饰名词或代词的从句叫定语从句,被修饰的名词或代词叫先行词,引导定语从句的有关系代词who,whom,whose,which,that等和关系副词where,when,why等,关系代词和关系副词在定语从句中担任句子成分。
二、状语从句:
表示“当…时候”的while,when,as的用法区别是:while从句中的谓语动词必须是延续性动词;表示带有规律性的“每当”或当主、从句谓语动词的动作发生有先后时,只能用when;当表示“一边…一边…”或“随着”时,只能用as,另外,用于此义的as所引导的时间状语从句谓语只能是动作动词,不能是状态动词。
三、名词性从句:
在句子中起名词作用的句子叫名词从句(NounClauses),名词从句的功能相当于名词词组,它在复合句中能担任主语、宾语、表语、同位语、介词宾语等,因此根据它在句中不同的语法功能,名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。
