过去完成时的用法

过去完成时的用法

一、构成方法

由 had 加动词的过去分词构成。　　　

二、用法说明

■表示在过去某一时刻或某一动作之前已经完成了的动作，即“过去的过去”。如：

She said she had never been to Paris. 她说她从未去过巴黎。

When the police arrived, the thieves had run away. 警察到达时，小偷们早就跑了。

By the time he was twelve, Edison had begun to make a living by himself. 到了十二岁那年，爱迪生开始自己谋生。

注意：过去完成时是一种相对时态，一定要有一个作参照的过去时间或过去动作作比较，否则，就不能用过去完成时。但下列3种情况虽然有是先后发生的两个过去动词，却同用一般过去时：

1. 先后发生的一系列动作，但并不强调先后时，最后两个动词用then，and，but 等连接。如：

On Saturday afternoon, Mrs Green went to the market, bought some bananas and visited her cousin. 星期下午，格林夫人去了市场，买了些香蕉，然后去看望了她的表姐。

2. 两个动作是紧接着发生的，可用一般过去时。如：

When I heard the news, I was very excited. 我听到那个消息时，非常高兴。

3. 叙述历史事实，可用一般过去时。如：

Our teacher told us that Columbus discovered America in 1492. 我们老师告诉我们哥伦布于1492年发现了美洲。

■表示从过去某一时刻开始一直延续到另一过去时刻的动作或状态。跟现在完成时一样，也常与 how long, for three days, before 等表示一段时间的状语连用。如：

When Jack arrived he learned Mary had been away for almost an hour. 当杰克到来时，他才了解到玛丽已经离开差不多一个小时了。

■表示未曾实现的希望或打算。表示希望或打算的动词，如hope, want, expect, think, suppose, plan, mean, intend等的过去完成时，后接不定式to do时，表示未曾实现的希望或打算，即“本来希望或打算做某事(但却没做) ”。如：

I had hoped to send him a Christmas card，but I forgot to do so. 我本来希望寄给他一张圣诞卡的，但我忘了寄了。

I had intended to come over to see you last night，but someone called and I couldn’t get away. 昨晚我本想去看你的，但有人来了我走不开。
