过去完成时

右侧笔记支持独立滚动。边听名师连读拆解，边对照右侧的语法事实与统计数据笔记。

现在完成时	过去完成时
have + done ^{(站在现在的部分/全部完成影响到现在)}	had + done ^{(站在过去的部分/全部完成影响到过去的当时)}
When he get there, she is not there.She has left. ^{（他到达那里时，她不在那里。她已经离开了。）强调的是目前情况}	When he got there, she was not there.She had left. ^{（他到达那里时，她不在那里。她已经离开了。）着重描述过去的情况}
常用连词 when，after，as soon as，until，by that time 等	常连用的副词如already，just，never，never…before 也常与过去完成时连用。

过去完成时与现在完成时放在一起为对比结构，通常情况下过去完成时会搭配一般过去时使用表示强调事件、动作发生的是先后顺序。

一般过去^(后)	过去完成时^(先)
I didn’t know that she was a famous actress until	you had told me.
The boys loved the zoo.	They had never seen wild animals before.
When he got there	she had left.
