it was then that是什么从句

问题描述

精选答案

1.当宾语从句表示的是科学真理、客观事实、格言或其他不受时间限制、影响的客观存在的情况时。

例如:Long ago,people didn’t know that the earth moves round the sun.很久以前,人们不知道地球是围绕着太阳运行的。It was not until then that I came to know that knowledge comes from practice.从那以后,我才知道知识来自实践主语从句，而把主语从句放到句末。此时，that也只起连接作用，但可以省略。比如，以上两个句子就存在这个问题，所以一般都会改为：It surprises us all (that) he will come to our village tomorrow.It is known to all (that) she used to be a spy. (二)如果句子是疑问句，则必须用带形式主语it的结构。如：That she is our English teacher is true. (她是我们的英语老师，是真的。)That he has been there twice is a fact. (他去过那儿两次了，是真的。)
