请问it不能代替which作定语从句主语吗?什么时候可以用it＋谓语?谢谢

Answer 1

IT 代替主语从句时候,可以用IT +谓语
It +不及物动词+ that-分句
It appears that…似乎……
It happens that…碰巧……
It occurred to me that…我突然想起……
It occurred to me that I forgot to send this letter
It happened that I came into the office at that time.
it seems(appears / doesn’t matter / makes no difference / ...)that ...
例如:It makes no difference whether he will attend the meeting or not.他是否会参加会议都无关紧要.
当用it作形式主语,而将主语从句放在句尾时,主语从句中的否定词常要前移至主句中.例如:
It doesn’t seem that they are from the same university.It doesn’t appear that we’ll have a sunny day tomorrow.
