一般过去将来时

一般过去将来时的构成肯定句:主语+be(was,were)going to+动词原形(v.原)+其它或:主语+would(should would)+动词原形+其它或:was/were+动词不定式否定句:主语+be not(wasn‘t,weren’t)以下2种时态考察较少+动词原形+其他或:主语+would(should或could)not+动词原形 +其它疑问句:Be(Was,Were)+主语+going to+动词原形+其它 或:Would(Should could)+主语+动词原形+其它1. 同一般将来时不一样,把系动词be变为过去式,把will,shall变为过去式。例:I didn't know if he would come.=I didn't know if he was going to come.我不知道他是否会来。She was sixty-six. In three years,she would be sixty-nine.她66岁了。三年后,她是69岁。She told us that she would not go with us,if it rained.她告诉我们,如果下雨,她就不和我们一起去了。I didn't know how to do it. What would be their ideas?我不知如何去做,他们会有什么想法呢?2. 过去将来时常可用来表示过去习惯性的动作。此时,不管什么人称,一律用would。过去将来时有时可带时间状语注意1'was/were going to + 动词原形'或'was/were +动词不定式完成式'可表示未能实现的过去将来时间的动作。2was/were about to do'was/were about to do'表示说话的瞬间就会发生的动作。3was/were on the point of doing提示'be about to do' 和 'be on the point of doing'结构一般不与表示将来的时间状语连用,但后面可以接when引导的分句。
