2025考研英语语法备考it 做形式主语

  it 做形式主语

  当主语从句处在句首时,有时谓语结构比较短,会形成头重脚轻的句式,不符合英语语言规则,因此可以将主语从句用it替代,而真正的主语从句置于句尾。常见的四种情况是:

  (1)It is+名词+主语从句;

  eg:It is a pity that you should have to leave.

  It is still a mystery what caused the accident.

  (2)It is+形容词+主语从句;

  eg:It is clear that the whole project is due to failure.

  It is certain that he will win the match.

  如果是It is necessary /important /strange /natural+that引导的主语从句,从句中的谓语动词一定要用should+动词原形;

  eg:It is necessary that one should master the skills of operating computer.

  It is important that we all should attend the meeting.

  It is strange that the man should have stuck to his silly ideas.

  (3) It is+过去分词(said /planed/expected/known) +主语从句;

  eg:It is said that President Bush will visit our school next week.

  It is known to all that the gun powder was first invented by the Chinese.

  It is suggested that the work should be done with great care.

  (4) It +系动词+形容词表语形式+主语从句

  eg:It seemed certain that he will win the prize.

  It happened that the two cheats were there.
