其他表达法：
1. was/were going to + 动词原形：He said that he was going to live in the
country when he retired.(他说他退休后要住在农村。)

school.(她说她放学后要打扫教室。)
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。
例如：Last Sunday we were going to visit the Great Wall, but it
rained.(上星期天我们本想去游览长城的，但却下雨了。)
2. "was/were about to do"表示说话的瞬间就会发生的动作。

例如：I'm glad you have come. I was on the point of calling you, but you've
saved me the trouble now.(很高兴你来了。我正准备给你打电话，现在你省去我这个麻烦了。)
4. "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。
例如：I was about to start when it suddenly began to rain.(我正要动身天突然下雨了。)
5. 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。
