Question

如题所述

Answer 1

回答如下：
英语的主语从句属于名词从句，名词从句包括主语从句、宾语从句、表语从句、同位语从句。
引导主语从句的连词有：连接词that、if、whether, 连接代词who、whom、which、whose，what连接副词when、where、why，how。其中that(无意义)、if(是否)、whether(是否)在从句中不作任何成分。另外，主语从句可后移至主句后面，并用形式主语it作主句主语。例如：
That he is ill is true = It is true that he is ill.
What he said is true= It is true what he said.
Whether(不能用If) he will go is not clear = It is not clear whether / if he will go.
Whoever breaks the law will be punished= It will be punished whoever breaks the law.
How we will go is unknown = It is unknown how we will go.

主语从句，即在复合句中充当主语成分的句子，例如"That he finished writing the composition in such a short time surprised us all"，他在很短的时间内写完作文让我们都很惊讶，此复合句主要描述的是某事让我们惊讶，某事就是该复合句的主语，因此“That he finished writing the composition in such a short time”便是该复合句的主语从句。 引导主语从句的连词主要有：从属连词：that whether 连接代词：who whoever whom whose what whatever whichwhichever连接副词：when where how why whenever wherever however

在句子中担当主语的从句就叫做主语从句，通常放在主句谓语动词之前或由形式主语it代替，而本身放在句子末尾。
