问题五

主语从句和宾语从句的句型结构主要有哪几种?

回答如下:
根据主语从句在句中的位置,其结构有以下两种:
1. 主语从句+谓语+其他;
2. It(形式主语)+谓语+主语从句(真正 的或逻辑主语)。例 如:
That he got injured yesterday is true.
It is true that he got injured yesterday.
宾语从句有动词宾语和介词宾语两种,也有形式宾语和真正或逻辑宾语的用法。例如:
I know who he is.
I am interested in what he said.
主语从句和宾语从句属于名词从句,其结构均是主语在前,谓语在后。连接词that和if引导的宾语从句不能作介词的宾语。例如:
They talked about whether (不能用if ) they would take a trip there on Saturday.
I hear (不能用 of /about ) that he is in hospital.
