He hadn’t finished his homework before he watched TV. 一般疑问句：____+主语+_____+其他? Had he finished his homework before he watched TV? 回答:Yes,主语+____. No,主语+_______. I had learned English for 1 year before I came here. had + done 句式转换在______上完成 had had done had not done Had done 特殊疑问句：特殊疑问词+一般疑问句 had hadn’t Yes, he had. No, he hadn’t. 过去完成时句式转换 hadn’t How long had you learned English before you came here? 句式转换练习： They had arrived home before it rained. 按要求完成下面的句子1. By the time I arrived, Tom had finished the work.  (对画线部分提问) What had Tom done by the time you arrived?  2. Jenny had already cleaned the room when I called her. (改为否定句)    Jenny hadn’t cleaned the room yet when I called her. 3. He had left before she could say a word.  (改为一般疑问句)    Had he left before she could say a word? 过去完成时判断依据(以下动作指过去的两个动作) by+过去时间(到…时/在…以前) by the end of+过去时间(在…以前/到…结束时) before+过去时间(在…以前) by the time+从句(一般过去时)(到…时/在…以前) 1. 由时间状语来判定。 与过去完成时连用的时间状语有： By 10 last night they had worked for 12 hours. I had been to Beijing twice by the end of last year. By the time I got outside, the bus had already left. We had planted 600 trees before last Friday. 2. 在when/before/after等引导的状语从句中，主从句动作发生有明显的先后关系，动作在前(先发生)的用____________，动作在后(后发生)的用____________。 过去完成时 一般过去时 After he had finished his homework, he went to bed. The train had left before he got to the station. 注意： 若主从句动作紧接着发生，那么主从句均用一般过去时。 After he closed the door, he left the classroom. 3. 在含有宾语从句的主从复合句中，当主句为一般过去时，且从句的动作先于主句的动作发生时，从句要用过去完成时。如told/said/knew/heard/realized/thought等动词的宾语从句中。 He told me that he had worked here for 5 years. I suddenly realized that I had left my ID card at home. He said that he had seen the film before. 4. 在含有定语从句的主从复合句中，如果叙述的是过去的事，先发生的常用过去完成时，后发生的动作用一般过去时。 I returned the book that I had borrowed. She found the key that she had lost. 5. 过去完成时是一个相对的时态，只有和过去的某个时间或动作相比较时才会用到，因此可以通过分析上下文来确定时态。(有时句中没有明显的时间状语，动作发生的时间先后需根据上下文判定)先发生的用过去完成时，后发生的用一般过去时。 I met Wang Tao in the street yesterday. We hadn't seen each other since he came to Beijing. The whole family were happy. She had just won the first place in the game. 过去完成时使用时，必须有或含有一个发生在过去的动作与其比较，即有“先发生”和“后发生”。“先发生”用过去完成时，“后发生”用一般过去时。 总结 注意 英语中，已经有了一个一般过去时表示在过去发生的动作，为什么还有过去完成时呢？ 要记住：过去完成时的关键概念是：假设在过去发生了两件(或以上)的事件，一件是A事件，另一件是B事件，如果A、B两个事件几乎是同时发生的，那就用一般过去时；但是，如果A、B两个事件不是同时发生的，怎么办呢？那就是：哪个事件先发生，就用过去完成时；哪个事件后发生，就用过去时。在上面的假设中，如果A事件先发生，A就用过去完成时；如果B事件先发生，B就用过去完成时；而不管两件事是用什么样的时间状语或其它形式表示的。  过去完成时与现在完成时的区别 1.现在完成时强调对现在的影响或结果；过去完成时强调对过去的影响或结果。 I have been to Beijing twice. I had been to Beijing twice by the end of last year. 2. 都与表示一段时间的状语连用，但现在完成时表示的动作为从过去延续到现在或与现在有关的动作(句中不可有表示过去特定时间的状语)；而过去完成时表示的动作为在过去某时之前已经完成的动作或延续到过去某时的动作(句中可有表示过去特定时间的状语)。 She had been ill for a week before she came back. (“回来”发生在过去某一时间，“生病”发生在这一时间之前，即“过去的过去”) She has been ill for a week. (现在仍然病着) 二者均可与already/ever/just/never/for/since连用 过去完成时与一般过去时的区别 一般过去时表示过去发生的动作或存在的状态；过去完成时主要体现在过去发生的两个动作先后有别，即比过去发生的某动作还要“过去”，两个动作中先发生的用过去完成时，后发生的用一般过去时。 She lived in New York last year. She had lived in New York for 8 years before she came to China. buy — have(have/has had) borrow — keep(have/has kept) die — be dead(have/has been dead) become — be(have/has been) leave(离开)—be away (from home/Beijing...)(have/has been away) join (the army)— be in (the army)(have/has been in) start/begin — be on(have/has been on) fall ill(生病) — be ill(have/has been ill) fall asleep或sleep — be asleep(have/has been asleep) get/have married或marry— be married(have/has been married) come back或return — be back(have/has been back) open/close — be open/closed(have/has been open/closed) finish — be over(have/has been over) get/catch a cold —have a cold(have/has had a cold) put on —wear(have/has worn) get to know —know(have/has known) get to/ arrive in /reach/come— be in(have/has been in) 非延续性动词——延续性动词(常用) Mary’s morning Mary had a terrible morning yesterday !
