高中英语 从属连词
高中英语从属连词一、概念从属连词,顾名思义就是连接一个从句的词。
我们一般说的从句仅仅指的是主从复合句中的从句部分。
注意:1. 主从复合句是由从句和主句组成的,也就是其中也有两个句子,只是这两个句子并不会像并列句一样都是并列的,而是有一种从属关系,比如其中一个句子做了另外一个句子的某个成分,比如宾语成分(则是宾语从句)、主语成分(则是主语从句)2. 从句一定有从属连词相连,只是某些情况下从属连词可能会被省略,如:定语从句中的关系代词(其实就是从属连词)在从句中做宾语时,从属连词(关系代词可以省略),如:I met the girl (that) I ever saved yesterday. 我昨天遇到了我曾经救过的女孩;再如:宾语从句的that一般也都是省略的,比如I believe (that) you are sure to come.我相信你一定会来的。
二、连词分类从句类型从句连词名词性从句:主宾表从句that(不做成分,无意思、仅具有连接作用)which who when where whywhose what how whetherif形容词性从句:定语从句that(在从句中替代先行词作主语和宾语)which who when where whywhose whom ofwhich(whom),most ofwhich,as副词性从句:状语从句无that(因为状语从句连词都要翻译成某个意义,that做连词往往没有意义,只有连接作用)when where why how before,after, until, while,because, so, if, unless,although, as同位语从句(其实也归结于名词性从句中,本文单独抽出来)that(不做成分,无意思、仅具有连接作用)注意:1.定语从句中没有what这个从属连词。
但是有as、whose 这种连词。
2. that只在定语从句中作主宾语成分,在任何其他从句中不做成分,也没有意思,只有连接作用。
