过去将来时

一、概念：

立足于过去某一时刻，从过去看将来，常用于宾语从句中。

二、标志词：

the next day(morning, year),the following month(week),etc.

三、基本用法：

表示过去的某时以后将要发生的动作。但这个"将来"时间绝不会延伸到“现在”;而仅限于“过去时间区域内”。由此可以看出，含这个时态的句子常带一个表示“过去某个时间点”的状语。这个状语或是一个短语，或是一个句子。这个时态常用于：

A)表示从过去某一时间来看将要发生的动作或存在的状态，一般用于主句为过去时的宾语从句中。如：

He said he would come here next Friday.

I knew that he would help us when we were in trouble.

B)表示过去的动作习惯或倾向;

The old man would sit on a bench in the quite park for hours without doing anything.

When I worked on that farm, I would get up at 5 am.

C)表示过去情况中的“愿望”、“倾向”，多用于否定句。

No matter how difficult the work was , he would keep on doing it until he accomplished it . 不管工作有多难，他总会坚持不懈地把它干完。

D)用于虚拟语气中：

If I were you, I would not do that.

If he were here, he would show us how to do it.
