将来时动词怎么变?
一、时态为一般将来时的时候,动词通常为动词原形,但在以be doing形式表示将来时的时候,动词为(doing)动名词形式。以下为几种表示将来时时态的形式:
1、shall / will / be going to +动词原形 例如:He will be back in a few days./He is going to be back in a few days.
2、be to do sth. 例如:We are to have a meeting tomorrow afternoon。
3、be +doing . 例如:She is leaving for Beijing.
4、be about to do sth. 例如:He is about to leave the room.
二、过去将来时一般由“助动词would(should)+动词原形”构成,也可以用“was (were) going to+动词原形”来表示.过去将来时表示从过去某一时间看将要发生的动作或存在的状态。
1、由were/was going to 表示过去将来时,例如:I thought the film was going to be very interesting.
2、用would表示过去将来时 例如:They told me that they would come home by air for the holiday.
总的来说,将来时中的动词形式多为动词原形,少数情况会是以be doing的形式存在。
