主语从句和表语从句

知识点

1.名词性从句引导词的选择

选择原则“缺什么,补什么,什么不缺,用that”

“什么不缺,用that”的意思是:如果从句中不缺任何成分,而且句意完整时,就用that来引导主语从句或表语从句以及其他的名词性从句。

2.whether 意为“是否”,引导的主语从句放在句首,不能用if 代替;但当用

it 作形式主语时,whether引导的主语从句放在句中或句末,此时可换用if. It is doubtful whether there’ll be any seats left.说不上是否还有座位了。

3.that 引导主语从句时,只起连接作用,不作任何成分,没有实际意义。在句

首时不可省略。What引导主语从句时既要起连接作用,又要在从句中作主语或宾语,在任何情况下都不能省略,它具有具体意义,表示“什么,所……

的(事、物、话)”,相当于all that/ everything that. Which引导主语从句也作成分,它表示选择的意义,常译为“那个”。如:That he survived in the earthquake is a miracle. 他在地震中幸免于难,这是个奇迹。

4.关系代词what, which, who引导主语、表语从句时含有疑问意义,而whatever,

whichever, whoever在引导名词性从句时,往往比what, which, who更强调,不表示疑问意义。而且whatever=all that/everything that; whichever=anything that; whoever=anyone who.另外,whatever=no matter what时引导状语从句。

如:Whatever is worth doing at all is worth doing well.凡是值得做的事情都值得好好地做。
