过去将来时表示从过去某时看将来要发生的动作或存在的状态．是在某一过去时之后发生的动作．我们可以理解为它是＂立足于过去，着眼于未来＂的一种时态．E.g. Li Ming said that you would be happy if you heard from me. 过去将来时还可表示过去习惯性的动作．E.g. Every evening Mr. Wang would go and talk with his students. 过去将来时常用在宾语从句中．主句为过去时，从句表示将要发生的事情．E.g. I didn't know if she would come. 它也常用于间接引语中．E.g. He told me that he would go on a trip to Beijing the next day.
其结构为＂would/should v". 第一人称用should，其它人称用would．E.g. I hoped I should be well again very soon. My mother told me she would go shopping. 过去将来时也可以用 "was/were going to v" 来表示．E.g. He said that he was going to have a walk with his mother. 注意：go , come, leave, start 等表示位置移动的动词，常用过去进行时表示一个当时按计划或安排近期将要发生的事情．E.g. He didn't say when he was coming.
常见错误是：
在条件状语从句和时间状语从句中忘记用一般过去时代替过去将来时．
例：He said that he was going to the Great Wall if it wouldn't rain (rain) the next Saturday.
答案：didn't rain
解析：条件状语从句和时间状语从句中一般不用过去将来时，而常用一般过去时表示在过去看来将要发生的动作．
