表示过去将要做的事
1. I didn't know if he would come.
我不知道他是否会来。
2. She was sixty-six. In three years，she would be sixty-nine.
她66岁了。三年后，她是69岁。
3. 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？
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。
4. This door wouldn't open.
这扇门老是打不开。
5. Whenever he had time，he would do some reading.
他一有时间，总是看书。
6. I would play with him when I was a child.
当我还是孩童时，总是和他一起玩。
"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。
7. 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。
被动：
8. I should be told about the thing.
应该有人告诉我这件事。
疑问：
9.Were they going to finish the work before the next day?
第二天他们能完成工作吗？
否定：
10. They were not going to go hiking unless they finished their homework.
除非他们完成作业，否则他们不会去远足。
因为will和be going to 后面都要跟原型
be 的原型是be
而been是过去分词
追问谢谢，不过可以帮一下过去将来进行时和过去将来被动语态的吗？
追答能否采纳 谢谢
追问但是你的答案和我提的问题不一致啊，还是非原创的。
