宾语从句that不可省的情况
在看别人说明用法的时候,有个句子不能理解.“当主语从句有it做其先行词时”能否举个例子解释说明下这句话?
这是主语从句:为了防止句子头重脚轻,通常把形式主语it放在句首位置,真正主语搁置于句末
(1)It is certain that he will win the match.
(2)It is true that he has made a very important discovery in
chemistry.
(3)It is very likely that they will hold a meeting.
(4)It is strange that he should do that.
