什么是过去将来时，怎么用（举例就可以了）

he was going to invite me

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存在的状态

结构：过去将来时由助动词should/would+动词原形构成。

Would常简缩为'd, 如I'd, you'd，he'd等；would not常缩写为wouldn't。

过去将来时常用在宾语从句中。如：

I didn't know if he would come.

They never knew that population would become a big problem.

She didn't tell me where she would go.

Betty said she would visit the Great Wall next Saturday.

过去将来时也可以用was/were going to +动词原形来表示。如：

I wasn't sure whether she was going to speak at the meeting.

I was sure that they were going to do that.
