本单元是关于手表真相的对话

Police 1: Could you just sign here please?
Tim: Yeah, sure. Can I do anything else to help?
Police 1: I think we have everything we need. We've been watching your boss, I mean, your ex-boss, for some time, and we've long suspected that he was involved in a counterfeiting ring. With the statement you've just given us, the CCTV evidence, and Mrs Hall's statement too, I think we've got enough to secure a conviction.
Tim: Mrs Hall?
Police 2: Janet Hall: the rather posh customer who bought a watch from you just before Christmas. She recognised almost immediately that it was a fake, so she came to us straight away. But she was adamant that you couldn't have been responsible. She said something about some lost money that you returned to her.
Tim: Oh yeah, that. But when you interviewed me the other week you really seemed to think that I'd stolen the watches.
Police 2 : Just doing our job, sir.

本单元的语言点是过去完成时，过去完成时表示过去的过去，请看下面的解释和例句

Past perfect

Past perfect - fomp3 过去完成时的形式
The past perfect is made from a subject, 'had' and the past participle (the third fomp3 of the verb).

Past perfect - meaning & use 过去完成时的意义和用法
The past perfect is used to make it clear that one event happened before another in the past. In episode 91 of the flatmates, Tim says:

"But when you interviewed me the other week you really seemed to think that I had stolen the watches."

Tim is talking about 2 events which both happened in the past: the police interview, and the theft of the watches. Because the theft of the watches happened before the police interview, Tim uses the past perfect: 'I had stolen'.

It does not matter which event is mentioned first - the tense makes it clear which one happened first. Tim could have said:

"But you really seemed to think that I had stolen the watches when you interviewed me the other week."

More examples:

I didn't have any money because I had lost my purse.

Tony knew Istanbul so well because he had been there several times.

Had John ever studied Japanese before he moved to Japan?

She only understood the book because she had seen the film.

We couldn't get a table because we hadn't booked in advance.


Adverbs with the past perfect 与过去完成时一起使用的副词
