Had you visited the museum before you moved to the city? 你搬到这座城市前曾参观过这个博物馆吗？ How many pictures from the spaceship had you got by nine o'clock last night? 直到昨晚九点，你收到了多少张来自宇宙飞船的照片？ [即学活用1] 单句语法填空 ①He said he __________ (work) in that factory since 1949. ②I didn't know a thing about the verbs，for I _______________ (not，study) my lesson. ③I returned the book that I ____________ (borrow). ④Helen said that she _________ (move) to another flat. ⑤We realized we ________ (lose) our way. 2．过去完成时的其他用法 (1)用于虚拟语气 在虚拟语气中，如果表示对过去情况的虚拟，则使用过去完成时。 If I had followed the doctor's advice，I wouldn't feel so bad now. 如果我当时听了医生的建议，现在就不会那么难受了。 If only you had worked with greater care! 你要是更仔细一些该多好！ I wish I had never met you before. 我希望以前从未见过你。 (2)表示过去未曾实现的希望、打算和意图 过去完成时表示过去未曾实现的希望、打算或意图，只适用于下列动词：expect(期待)，hope(希望)，intend(打算)，mean(打算)，suppose(料想)，think(认为)，want(想要)等。 We had hoped that you would be able to visit us. 我们原本希望你会来拜访我们。 I had meant to take a good holiday this year，but I was not able to leave. 我本打算今年好好去度假，只是脱不开身。 (3)与过去完成时连用的时间状语 与过去完成时连用的时间状语可以是already(已经)，yet(仍然)，still(还)，just(刚刚)，ever(曾经)，never(从来没有)等，也可以是by(截止到)，before(在……之前)，until(直到)，as soon as(一……就)等引导的词组或从句。 When I came back at midnight，she still hadn't finished her homework yet. 我半夜回来时，她还没有做完作业。 I had just stopped my car when I noticed a cat lying on the ground. 我刚把车停下，就注意到地上躺着一只猫。 By Tuesday he hadn't done it. 到星期二他还没有做。 (4)用过去完成时的特定句型 过去完成时还可用在hardly...when...，no sooner...than...，It was the first(second，etc)time (that)...等固定句型中。 Hardly had he begun to speak when the audience interrupted him. 他刚开始演讲，听众就打断了他。 No sooner had he arrived than he went away again.他刚到就又走了。 It was the third time that he had been out of work that year. 这是他那一年第三次失业。 [即学活用2] 单句语法填空 ①How I wish I __________ (work) harder before. ②He ___________ (plan) to meet his father at the airport，but he was too busy. ③By the end of last month，we ___________(learn) 2，000 English words. ④Hardly had the game begun when it _______ (start) raining. ⑤It was the first time that I _______________ (experience) Virtual Reality. 3．过去完成时与其他时态的区别 (1)过去完成时与一般过去时的区别 过去完成时在时间上强调“过去的过去”，而一般过去时只强调过去某一特定的时间。 比较：They had arrived at the station by ten yesterday. They arrived at the station at ten yesterday. 当两个或两个以上接连发生的动作用 and 或 but 连接时，按时间顺序，只需用一般过去时来代替过去完成时；另外，在 before, after, as soon as 引导的从句中，由于这些连词本身已经表示出时间的先后，因此也可以用一般过去时来代替过去完成时。 He entered the room，turned on the light and read an evening paper. 他走进房间，打开灯，读了一份晚报。 (2)过去完成时与现在完成时的区别 现在完成时表示的动作发生在过去，但对现在产生一定的结果或影响；过去完成时则是一个相对的时态，以过去时间为基点，它所表示的动作不仅发生在过去，更强调“过去的过去”，只有和过去某时或某动作相比较时，才用到它。 I have learned 1，000 English words so far. 到目前为止我已经学会了1000个英语单词。 I had learned 1，000 English words till then. 到那时为止我已经学会了1000个英语单词。 [即学活用3] 单句语法填空 ①When she heard that her father ________(die)in the accident，she _____ (burst) out crying. ②The concert ___________(start).We had to look for our seats in the dark. ③I ______________(enter) a new stage of life since entering high school and learned to be independent. ④Her father ____ (die) five years ago and he _________ (live) by himself ever since. ⑤They ___________ (plant) six hundred trees before last Wednesday.
