1.  你懂得如何精准地“回望过去” 么？

前面两课，我们重点复习了英文中“展望未来”，这课我们重点复习“回望过去”

在53课的“时态全家福”中我们探讨了学习时态的基本问题：

用英语沟通的时候，如何确定时态呢？

确定时态的核心思维：__________________

“过去完成时”核心思维：________________（结合第14课复习）

“过去完成进行时”核心思维：____________ 【听记1】

这课，我们重点来复习“过去完成进行时”

课文回放1： 

Firemen had been fighting the forest fire for nearly three weeks before they could get it under control.

Firemen had put out the forest fire before it went out of control.

留意两个细节用词：

(1)before这里表示 “才...”

复习: 57课

具体怎么使用呢？

两件事先后发生A happened before B happened【听记2】

1）________，则before对应中文中的“才”

Firemen had been fighting the forest fire for nearly three weeks before they could get it under control.

2）_________，则before对应中文中的“就”

Firemen had been fighting the forest fire for less than an hour before the fire was almost put out.

3）_________，则before对应中文中的“然后”

Firemen had put out the fire before they saved a boy in the house.

(2) could

could表示“潜在能力”，

was able to可以表示“成功做到”【回顾第43课】

为啥文章中用的是“could”？

比较：Firemen had been fighting the forest fire for nearly three weeks before they were able to get it under control.

课文回放2：

The planes had been planting seed for nearly a month when it began to rain.

比较：

The planes had planted five tons of the special type of grass-seed when it began to rain.

场景造句： 

1）When I found this course, I had been learning English in the wrong way for years.

I had been learning English in the wrong way for years before I found this course.

2）We had been waiting for two hours in the freezing cold before the train finally arrived.

3）Jack and I were just back to the hotel. We had been skiing in the mountains.

注意：这里的had been skiing表达的是一直延续下去的动作么？

4）I had been trying to get in contact with Susan, but was unable to do so until I met her last Sunday at a cafe.

注意：trying to get in contact with her是一直延续的动作么？

所以：英文中“进行”这个动作状态的含义：_____________【听记3】

The man had been gambling for years before he went broke.

区别：The man had lost one million dollars before he went broke.

2.  什么？过去进行时还可以表示“过去将来”？

Winter was coming on and the hills threatened the surrounding villages with destruction, for heavy rain would not only wash away the soil but would cause serious floods as well.

语言点解析： 

1) Winter was coming on....  

注意时态：was coming不是正在来，而是即将来临。

比如：

We were excited as we were flying to Paris the following week.

Mike was busy packing , for he was leaving Shanghai that night.

2) “come on”

come on = start

The snow came on just before we had our dinner on Spring Festival Eve.

When we finished our dinner, the Spring Festival Gala came on.

听记答案 

1. 穿越时间坐标，切换动作状态；过去的过去；过去的过去+持续发生

2. A持续的时间很长；A持续的时间很短；不强调A发生的时间

3. 不仅包含延续还有重复
