英语时态时态毫无疑问是今年 云南省专升本英语中最重要的英语的语法內容，学精时态基础就拿到了英语的语法的江山半壁。今日我为学生们小结的是过去完成时，请大伙儿用心备考。

1、过去完成时的界定

过去完成时既可表明以往某一時间或动作以前所发生的事儿(常见时间状语有already, before, ever, just, never, still, yet)，也可表明以往某一時间或动作以前所发生的动作一直不断到以往某一時间(常接时间状语：since 时间点, for 时间范围)。如：

When I got to the station, the train had left. 当我们抵达地铁站时，列车早已提走了。

We had learnt fifteen lessons by last week. 到上星期才行，大家学完后十五篇课文内容。

He had stayed here for two days before he left. 他走以前在这儿呆了二天。

He said that he had lived there since he was ten. 他说他十岁起就住在那里了。

2、过去完成时的构造

过去完成时由“had 过去分词”组成。

过去完成时的运用

(1) 与过去完成时并用的时间状语能够各种各样，应用它的关键根据是看其是不是发生在“过去的过去”。如：

He had learnt some English before I went here. 在来这里以前我教过一些英语。

He had written three stories by last year. 到上年他早已写了三篇小故事。

We had cleaned the room when he got there. 当他到那里时，大家早已把房屋弄整洁了。

He went there after he had finished his work. 他把事做了以后，就去哪了。

留意：当主句跟由before, after, as soon as所正确引导的時间从句的动作联接很密不可分时，从句也能用一般过去时。

He went there after he read the letter. 他看过那封信后就去那儿了。

(2) 过去完成时还常常用以主句为过去式的宾语从句中。如：

He said he had been a soldier. 他说他当兵。

They said they had seen the film. 有人说这幕影片她们看了。

(3) 在hardly / scarcely …when…, no sooner…than… 2个构造中的主句一般要用过去完成时。如：

Hardly had I told her the news when she began to cry out. 她一听见这一信息就痛哭了起來。

Scarcely had he finished his supper when he went out. 他已吃了晚餐就出去了。

No sooner had he fallen asleep than he lay down on the bed. 他一躺下床边就睡觉了。

(4) 形容词expect, hope, suppose, think, want等的过去完成时能用来表明未完成的方案、准备或期待。如：

I had hoped to see you. 我曾期待来看。

He had wanted to buy a house in Beijing. 他本想北京买栋房屋。

3、过去完成时与一般过去时

(1) 过去完成时表明以以往某時间为起始点之前所发生的动作或存有的情况，即：过去完成时注重“过去的过去”，而一般过去时只表明以现在的时间为起始点之前所发生的事儿或存有的情况。如：

He studied there two years ago. 他在那里学了2年。(离如今2年)

He said he had studied there two years ago. 他说他在那里学了2年。(离他说话时2年)

(2) 表明以往某一時间之前所持续发生的2个或2个之上的动作时，一般用and, then, but依照动作的顺序联接，这时一般用一般过去时而无需过去完成时。如：

He said he went the shop and bought some food. 他说他去店铺买来一些食品类。
