英语中,过去将来时(Future in the Past)是一种表达过去发生的未来事件的动词时态。它通常用于叙述过去某一时刻之前的未来事件。过去将来时可以通过以下四种结构来表达:
结构一:would + 动词原形
这是最常用的一种表达过去将来时的结构。例如:
- He said he would come to the party tonight.(他说他今晚会来参加派对。)
- I knew she would be late for the meeting.(我知道她会迟到开会。)
结构二:was/were going to + 动词原形
这种结构表达的是过去某一时刻已经计划好的未来事件。例如:
- I was going to buy a new car, but then I changed my mind.(我原本打算买一辆新车,但后来改变了主意。)
- He said he was going to propose to his girlfriend last night.(他说他昨晚会向女友求婚。)
结构三:was/were about to + 动词原形
这种结构表达的是过去某一时刻即将发生的未来事件。例如:
- We were about to leave the office when the boss called us back.(我们正要离开办公室,老板叫我们回来了。)
- She was about to board the plane when she realized she forgot her passport.(她正要上飞机时意识到忘了带护照。)
结构四:past continuous + would + 动词原形
这种结构表示过去某一时刻正在发生的事情,但是在这个事件发生之前,已经有了一个计划好的未来事件。例如:
- I was watching TV when my friend called and said he would come over.(我正在看电视,朋友打电话说他会过来。)
- They were having dinner when the power went out. They knew they would have to use candles.(他们正在吃饭,停电了,他们知道得用蜡烛。)
以上就是过去将来时的四种结构,希望对大家有所帮助。
