(2)否定句：主语＋had＋nt＋动词过去分词＋其他。
(3)疑问句：Had＋主语＋动词过去分词＋其他？肯定回答：Yes，主语＋had.否定回答：N，主语＋hadn't.

(5)被动语态：主语＋had (nt)＋been＋动词过去分词 ＋其他。

三、过去完成被动时基本用法
1. 表示过去某一时间或某一动作前已发生且已完成的动作或状态。如：The wrk had been finished by us by nine ’clck yesterday.Grace realized a mistake had been made by her.The prject had been cmpleted by the end f 1999.
2．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，常 使用过去完成时。
Mr.Smith died yesterday. He had been a gd friend f mine.
3. 在含有定语从句的主从复合句中，如果叙述过去的 事，先发生的动作常用过去完成时。
I returned the bk that I had brrwed.
4.过去完成时常常用在tld，said，knew，heard， thught等动词后的宾语从句(或间接引语)中，这 时从句中的动作发生在主句表示的过去的动作之前。
He said that he had knwn her well.I thught I had sent the letter a week befre.
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，用一般过去时。 如：when, befre, after, as sn as, till / until引导 的复合句。
When I wke up, it had already stpped raining.
She didn't g t bed until she had finished her wrk.
注意：如果两个动作紧接着发生，则常常不用过去完成时，特别是在包含befre和after的复合句中，因为从句的动作和主句的动作发生的先后顺序已经非常明确，可以用一般过去时代替过去完成时。
例:① We had hped that yu wuld be able t visit us.② I had meant t take a gd hliday this year, but I was nt able t leave.
6．动词think，want，hpe，mean，plan，intend 等用过去完成时来表示过去未曾实现的想法、希 望、打算或意图等。
1)用于wish后的宾语从句中，表示对过去未做成的事情的某种感叹或愿望。如：I wish I (be) there at that time.那时候我要在那儿就好了。（事实上我不在那儿。）I wish I (tell) him abut it.我要是没告诉他那事就好了。（事实上我告诉他了。）
四、过去完成时态常见的固定结构.
2)用于对过去事实进行虚拟的条件句中。如：If I had hurried, I wuldn't have missed the train.如果我快点的话，我就不会误了火车。If yu had been at the party, yu wuld have met him. 如果你去了晚会，你就会见到他的。
3)过去完成时常用在引述动词一般过去时后的间接引语中。They said that they had planted the trees n the hillside.他们说他们把树种在山坡上了。Jack tld me he （read） the bk befre.杰克告诉我他以前读过那本书。Julie said she （g）t see him the day befre.朱莉说她前一天已经去看过他。
4) think，want，hpe，plan，intend，mean和suppse等词的过去完成时可以用来表示本来要做而没做或无法做的事，或没有实现的希望或意图。Eve had hped t see mre f China.伊芙曾希望在中国多观光一番。I had intended t be there n time.我本打算准时去的。
动词think, want, hpe, mean, plan, intend, wish, expect, suppse等用过去完成时来表示过去未曾实现的想法、希望、打算或意图等。
1. We had intended t have a barbecue in the pen air, but the weather was bad.2. I _________ (wish) t becme a dctr, but I studied law at cllege. 3. They ____________ (plan) t see us ff at the airprt.

I had n sner reached hme than it began t rain. 当hardly /scarcely, n sner位于句首时，主句要倒装。Hardly had we left the huse when it began t rain.Hardly Laura sat dwn when the phne rang.N sner I walked in the dr than they （arrive） .
(6)用于过去完成时的时间状语：by+ 过去时间点；by the end f +过去时间点；by the time +过去时间点；befre +过去时间点。I (finish) reading the nvel by 9 ’clck last night.By the end f that year, Henry (cllect) mre than a thusand pstcards.They (plant) 600 trees befre last Wednesday. By the time they arrived, we (get) everything ready.
