That was the first /
second…time that-从句(必须使用过去完成时)
例:①It is the second time that she has visited the Great Wall.
②This was the first time that I had come late to school.
(4) It was +时间点 + when -从句
例: It was evening when we got home.
=It was evening in which we got home.
(5) It was / will be + some time + before -从句
例:①过了5年他们才从北大毕业。
It was five years before they finally graduated from Beijing University.
②不久,我们就要从我们学校毕业了。
It won't be long before we graduate from our school.
二、it作形式主语
【完成例句】
根据语境补全句子
(8) It is possible for me to make a tour around the world.
【结论】代替由不定式、动名词或从句所表示的真正主语。为平衡句子,通常把不定式作主语改为it 作形式主语。
三、it作形式宾语
【例句观察】
①How did it come about that so many people were attacked?
② She feels it hard to get in touch with her old friend.
