过去完成时总结 篇1

用法:在过去的时间里,两个动作中,发生在前的那个动作要用过去完成时。

结构:had+过去分词

after she had finished her homework, she went shopping.

they had sold the car before i asked the price.

the train had left before i arrived at the station.

after/before引导的时间状语从句放在句首要在句子后面加逗号,如果放在主句后则不用加。

1.变疑问句将助动词移到句首

had she finished her homework?

2. 变否定句在助动词后面加not

she hadn’t finished her homework.

3. 肯定回答及否定回答

yes, she had. no, she hadn’t.

4.特殊疑问句:

what had she done?
