I. 时间状语从句
II. 过去完成时
时间状语从句
. 常见的连接时间状语从句的连接词有:
when, while, as, before, after, until/till, since,
ever since, whenever, as soon as, no sooner… than,
hardly / scarcely… when 等
When
When 还有意义为‘这时’，(at this time)‘那时’(at that time) 常用于下列句型：
Somebody was doing something when……某人正在做 ……突然 ……
Somebody was about to do something when…….某人正要做
……突然 ……
Somebody had just done something when……某人刚刚干了……这时……

1, I was
reading English when my teacher came in.
2, I was about
to talk in the classroom when the teacher came in.
3, I had just
made the mistake when the teacher came in .

While
观察：
While they were doing homework, someone broke into the
house.
While he was still a teenager, he was a big star.
分析：while引导的从句表示“在……过程中”，强调某一段时间内主句和从句的动作在同一时期发生。从句的动作表示较长时间，因此常用延续性动词。
While 表示强烈的对比关系，可译成“然而”
She is tall while I am short.
While I was studying English, he was playing football.

As
试观察：
1) As they were picking tea, the girls were singing
happily.
强调两个动作同时进行
2) As he grew older, he found it difficult to compose
good music.
两种情况一起发展变化
分析：as引导的从句表示“当……时；一边……一边……”，主句和从句的动作同时发生，强调伴随。有时可译为“随着”。

过去完成时
1过去完成时的构成:
“助动词had+过去分词”
The public
wondered why the president hadn’t attended the top conference.
2. 过去完成时的用法:
1). 过去完成时主要用来表明在某个时间或动作之前已经发生的动作, 它表示时间是“过去的过去”。如:
The patient had died when the doctor arrived.
Up until then they had just finished half the work.
He had pressed the button before we could stop him.
When I had finished my everyday work, I did some
gardening.
2). 如果发生的动作很短暂, 或两个动作紧接着发生, 则常用一般过去时代替过去完成时。尤其是在含有before, after, as
soon as的复合句中, 因为它们本身的词义就可以表示出先后顺序。如:
Just before I left New York, I sent an e-mail to Mr White, my
teacher in the university.

3). 过去完成时还可以表示未能实现的希望、愿望等, 常用的动词有except, hope, mean, suppose, think 等。如:
I had hoped to send him a telegram to congratulate him
on his marriage, but didn’t manage it.
Mother had expected me to come to her birthday party,
but I really had a lot of important work to do.
Note:
当动作紧接着发生, 次序明显时, 只需用一般过去时。
When he got home from work, he was very tired. He
opened the door, turned on the light, washed his face and went to bed without
taking off his clothes.
2.与某个时间段或时间点连用时, 一般过去时表示动作在这个时间发生, 而过去完成时表示动作在这个时间之前就已经完成。如:
He learned Russian during his stay in Russia.

He had already learned Russian during his stay in Russia.
3. 在间接引语中，与过去完成时连用的时间状语从句常用一般过去时代替过去完成时。如：
He told me somebody had phoned when I was out.
John said the film had been on five minutes when he
got to the cinema.
