Yes, I had. / No, I had三、语法判定 1. 由时间状语来判定 一般说来，各种时态都有特定的时间状语。与过去完成时连用的时间语有： （ 1 ） by + 过去的时间点。如： I had finished reading the novel by nine o'clock last night. （ 2 ） by the end of + 过去的时间点。 如： We had learned over two thousand English words by the end of last term. （ 3 ） before + 过去的时间点。 如： Before 10:00 yesterday, he had finished his homework. ，是指过去某一动作之前已经发生或”过去的过去“过去完成时表示 来判定。”过去的过去“2.

完成的动作，即动作有先后关系，动作在前的用过去完成时，在后的用一般过去时。 She said she had seen the film 4 times. 四、用法 1、表示在过去动作之前已经发生的动作或存在的状态。 例如 ：Most of the guest had left when he arrived at the party. （即：客人在他到之前已经离开了。） They had already had breakfast before they arrived at the hotel.（即：吃饭在先，他们到达在后 1、过去完成时还可以表示从过去某一时间开始，持续到过去另一时间的动作或状态。 例如 ：He had worked in the factory for five years before he moved here . By the time I got there, it had already finished. Ann had lived in a cottage for sixty years ever since she was born. 3、叙述过去发生的事情，在已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，使用过去完成时。 例如： Mr. Smith died yesterday. He had been a good friend of mine. 4、过去完成时常常用在told, said, knew, heard, thought等动词后的宾语从句（或间接引语）中，这从句中的动作发生在主句表示的过去的动作之前。 例如： He said that he had known her well. 他说他很熟悉她。 5、状语从句：在过去不同时间发生的两个动作中，发生在前，用过去完成时；发生在后，用一般去时。 如:when, before, after, as soon as, till/until引导的 例如： ________________________________________________________. 我醒来时雨已停了。6、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。 如： I returned the book that I had borrowed. 我已归还了我借的书。 五、其它句型 1. It was the first time that 从句中，从句用过去完成时。 It was the first time that he had seen so beautiful scenery。 2、.Hardly/scarcely....when 与no sooner than 引导的时间状语从句中，从句是一般过去时时， 主句就用过去完成时。
