高考英语语法复习名词性从句

Grammar名词性从句(Noun Clauses)

名词性从句相当于名词，可分别做主句的主 语、表语、(动词/介词的)宾语和同位语。因此， 名词性从句可分为: The Subject Clause (主语从句),The Object Clause (宾语从句), The Predicative Clause (表语从句), The Appositive Clause (同位语从句)

主语从句What you said sounds reasonable.

宾语从句：Nobody knows who broke the glass. I walked over to where he sat.

表语从句：This is what I was asked to do.

同位语从句：The idea that we’ll go out for a picnic is great.

引导名词性从句的连词：1. 从属连词：that (无词义，在句中不充当任何成分) if / whether (有词义“是否”,但不充当任何成分) 2. 连 接 代 词 ： who, whom, whose, what, which, whatever(有词义，在句中充当主语、表语、宾语 或定语) 3.连接副词： when, where, why, how, how many, how long, how far, however, whenever, wherever… (有词义，在句中充当状语)
