关于过去完成时的用法
过去完成时表示发生在过去的两个动作在前的那一个,它表示句子中描述的动作发生在“过去的过去”。下面是小编为您收集整理关于过去完成时的用法了,欢迎阅读!
过去完成时的用法1
过去完成时的基本形式:
过去完成时由had+过去分词构成,因此无人称变化
肯定式:I had/I'd worked等
否定式:I had not/hadn't worked等
疑问式:had I worked等
否定疑问式:had I not/hadn't I worked等
过去完成时的时态用法:
1. 过去完成时是与现在完成时相当的过去式:
现在完成时:Ann has just left.If you hurry you’ll catch her.(安刚刚走。如果你快一点,就能追上她。)
过去完成时:When I arrived Ann had just left.(我到的时候,安刚刚离开。)
但是,过去完成时不像现在完成时那样限于表达未指明时间的动作,因此可以说:He had left his case on the 4∶40 train.(他把手提箱丢在4点40分的火车上了。)
2.现在完成时可以和 since/for/always等词连用,表示一个开始于过去并仍在继续或刚刚结束的动:
与此同理,过去完成时也可以用来表示在所说的过去某一时刻之前就已开始的动作。
1)在该时刻仍然在继续。
例如:Bill was in uniform when I met him.He had been a soldier for ten years.(我遇到比尔的时候,他身穿军服。那时他已经当了十年兵了。)
2)在该时刻停止或刚刚停止。
例如:The old oak tree, which had stood in the churchyard for 300 years, suddenly crashed to the ground.(屹立在教堂墓地上已300百年之久的老橡树突然间哗啦一声巨响倒在地上。)
但应注意,过去完成时还可以用来表示:
3)在所说时刻之前某一时候停止的'动作。
例如:He had served in the army for ten years; then he retired and married.(他在军队里服役十年,后来退伍并结了婚。)
3. 过去完成时也是一般过去时的过去时,用来表示叙述者或主语在过去的某一时刻回顾更早的动作:
例如:He met her in Paris in 1977.He had last seen her ten years before.Herhair had been grey then; now it was white.(1977年他在巴黎遇见了她。他上一次见到她是十年之前。那时她的头发是灰白的,这时已经全白了。)

前一句应用过去进行时。
注意:had no … when还没等……就……

过去完成时的用法3
表示在过去某一时刻或动作以前完成了的动作,即“过去的过去”,可以用“ by、before等”介词短语或一个时间状语从句来表示,也可以用一个表示过去的动作来表示,还可以通过上下文来表示。
叙述过去发生的事,在以叙述了过去发生的事情后,反过来追述或补述以前发生的动作时,常常用过去完成时。
在含有定语从句的.主从复合句中,如果叙述的是过去的事,先发生的动作常用过去完成时。
过去完成时常常用在宾语从句(或间接引语)中,这时从句中的动作发生在主句表示的过去的动作之前。
在包含有“when、until等”连词的复合句中,如果主句谓语动词和从句谓语动词所表示的过去动作不是同时发生的,那么先发生的动作常用过去完成时表示。
动词“think、want、hope、mean、plan、intend等”用过去完成时表示过去未曾实现的想法,希望,打算或意图等。
过去完成时还可用在“hardly...when,no sonner...than...,It was the first ( second,etc)time(that)...等”固定句型中。
过去完成时的用法4
过去完成时(The Past Perfect Tense):表示过去某一时间或动作以前已经发生或完成了的动作,对过去的某一点造成的某种影响或是结果,用来指在另一个过去行动之前就已经完成了的事件。它表示动作发生的时间是“过去的过去”,侧重事情的结果。
一、 概念: 表示过去的过去,其构成是had +过去分词。
1.肯定句:主语+had+动词过去分词+其他.
2.否定句:主语+had+not+动词过去分词+其他.
3.疑问句:Had+主语+动词过去分词+其他?
肯定回答:Yes,主语+had.
否定回答:No,主语+hadn't.
4.特殊疑问句:特殊疑问词或词组+had+主语+过去分词+其他?
5.被动语态:主语+had(not) +been+动词过去分词+其他.
二、 用法:
1. 表示某一动作在过去某一时刻之前已完成。例如:
He had gone to bed by 10:00 last night. (昨夜十点钟之前他已上床去睡了。)
2. 与一般过去时搭配,表达某一动作在过去的动作发生时已完成。例如:
The train had started when I got to the station. (当我到达车站时火车已开走了。)
The minute I saw a lady getting off the bus, I knew it was she, for I had seen her before. (我一看到正在下公共汽车的那位女士就知道是她,因为我以前看见过她。)
解说: 使用过去完成时在简单句里表达某一动作在过去的某一时刻已完成时,该过去的时刻常以“by +过去时间”的短语来表达。
例如下面的说法是不正确的:
He had gone to bed at 10:00 last night.
若是要说“at 10:00 last night”就必须用一般过去时“He went to bed...”。 请再观察下面的句子试比较:
It had rained yesterday. (误)
It rained yesterday.(正)
或许你会说:“昨天下了雨,可是今天已放晴了,下雨已是过去的事,而且已经下完了,所以就用过去完成时……。”这就是最令同学们对一般过去时和过去完成时感到混淆和困惑的。实际上只要我们了解下面的'两点原则就可以消除这种现象。
1. 由过去的时间作状语来修饰动词的句子都使用一般过去时。
2. 除非从谈话的先后关系和上下文关系对过去的动作完成的基准点可以确定以外,应该避免在简单句中使用过去完成时。
