(语法项目——过去完成时)
语境中体悟
Lonesome George was the last Pinta Island tortoise.He died in 2012.After George's death, the Pinta Island tortoise was declared extinct.The extinction of the Pinta Island tortoise is blamed on humans.Before humans arrived on the island, the species had lived in isolation and had eaten the plants that naturally grew there.① George was discovered many years after their arrival, and by then humans had introduced new species that competed for the food the tortoises ate②.After goats in particular had been brought to the island③, the Pinta Island tortoise population declined.Eventually only George remained.
[语法入门]
句①中,before 引导的时间状语从句中使用了一般过去时,主句中使用了过去完成时;
句②中,时间状语为by then,故句子使用过去完成时;
句③中使用了过去完成时的被动语态。
学案中理清
一、过去完成时的构成及基本用法
1.过去完成时的构成为:had+过去分词,否定式是在had后加not,疑问式是把had提前。
2.表示在过去某一时刻之前已经完成了的动作,即“过去的过去”。时间状语为by、before等介词(短语)搭配过去的时间点,或使用了含过去时的时间状语从句。
3.表示由过去的某一时刻开始,一直延续到过去另一时间的动作或状态,时间状语常用“for+时间段”或“since+时间点”。
4.表示未曾实现的愿望或打算,主要用于hope、 want、 expect、 think、 suppose、 plan、 mean、 intend等动词。

⑥He_had_not_expected the pain to be unendurable.
他没料到会如此疼痛难忍。
二、主从复合句中的过去完成时
1.在主从复合句中,若主从句的动作都发生在过去,且有先后关系,动作在前的要用过去完成时,动作在后的要用一般过去时。
2.在包含before和after的主从复合句中,因为从句动作和主句动作发生的先后顺序已经非常明确,可以用一般过去时代替过去完成时。
The train (had) started before I reached the station.
在我到达车站之前,火车已经开了。
After he (had) arrived in England, he worked hard to improve his English.

三、固定句型中的过去完成时
1.主语+had hardly/scarcely/no sooner+过去分词+when/than从句(从句用一般过去时;hardly、 scarcely、 no sooner位于句首时,主句要用部分倒装);
2.It was+一段时间+since从句(从句用过去完成时);
3.It was the first/second ...time+that从句(从句用过去完成时);
4.主句(过去完成时)+by the time ...(从句用一般过去时)。

时态
相同点
不同点

的时间状语
动作发生在过去,常有具体的过去时间状语
过去完成时
动作发生在“过去的过去”,含不具体的过去时间状语

|名师点津|过去完成时不能单独出现,它必须有一个过去的时间作参照点,而一般过去时则可以独立使用。
2.过去完成时与现在完成时的区别
时态
相同点
不同点
现在完成时
动作都发生
在过去
以“现在”作为时间参照来谈论过去
过去完成时
以“过去”作为时间参照来谈论更远的过去
