Definition 一般过去将来时表示从过去的某一时间来看将来要发生的动作或呈现的状态。在英语时态中，“时“指动作发生的时间，”态“指动作的样子和状态。 一般过去将来时的出发点是过去，即从过去某一时刻看以后要发生的动作或状态。 那时所预见的情况 现在 过去 过去的过去 过去将来时的构成 肯定句： （1）主语+be（was或were）going to+动词原形（v.原）+其它 （2）主语+would+动词原形+其它 （3）was/were+动词不定式 Note:1.同一般将来时不一样，把动词be变为过去式，把will，shall变为过去式。 例句：I didn't know if he would come.=I didn't know if he was going to come. She was sixty-six. In three years，she would be sixty-nine. 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 3."was/were going to + 动原"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。 4."was/were about to do"表示说话的瞬间就会发生的动作。 5."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。 e.g. I was about to do my homework when my father arrived home. 用法 一、would+动词原形"构成过去将来时，常表示根据计划或安排即将发生的事。 例1：He said he would come to see me.他说他要来看我。例2：He told me he would go to Beijing.他告诉我他将去北京。 二、"was /were+going to+动词原形"也可表示根据计划或安排即将发生的事。 例1：She said she was going to start at once.她说她将立即出发。 例2：I was told that he was going to return home.他告诉我他准备要回家。 "was /were+going to+动词原形"还可表示根据当时情况判断有可能但不一定会发生某事。 例：It seemed as if it was going to rain.看来好像要下雨。 三、某些动词的过去进行时可表示过去将来时come,go,leave,arrive,start等严格按照时间表发生的表起止的动词可用过去进行时代替过去将来时。 例1：He said the train was leaving at six the next morning.他说火车第二天早晨出发。 例2：She told me she was coming to see me.她告诉我她要来看我。 Read the sentences.
