Unit 12 Life is full of the unexpected.
过去完成时时态
一、过去完成时的概念
过去完成时表示在过去的某一时间或动作之前已经完成的动作，即表示＂过去的过去＂。
Mr Black told me that he had seen the movie three times. 布莱克先生告诉我这部电影他已经看过三遍了。
二、过去完成时的结构：主语+had+动词过去分词(done)
1. 肯定句：主语+had+过去分词+其他.
2. 否定式：主语+had+not+过去分词+其他. 缩写形式：hadn’t
3. 一般疑问句：Had+主语+过去分词+其他?
肯定回答：Yes, 主语+had. 否定回答：No,主语+hadn’t.
4. 特殊疑问句：特殊疑问词或词组+一般疑问句(had+主语+过去分词+其他)?
5. 被动语态：主语+had(not) +been+过去分词+其他.
【巧记口诀】
巧学过去完成时
过去完成时态不算难，形式要向完成时态看。
have变成had不怠慢，断定过去之前是关键。
三、过去完成时的判断依据
1. 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。常见的时间状语（从句）由by，before，when，by the end of，by the time，until等引导。
They had planted six hundred trees before last Wednesday. 他们在上周三前已经种植了600颗树。
I had finished reading the novel by nine o’clock last night. 我昨天晚上九点就已经读完了这本小说。
2. 过去完成时还可表示过去某一时刻之前发生的动作或状态持续到过去某个时间，常与＂for+时间段＂或＂since+时间点＂连用。
When Jack arrived, Mary had been away for almost an hour. 当杰克到达时，玛丽已经离开差不多一个小时了。
3. 过去完成时经常用于主句为一般过去时的宾语从句中，表示从句动作先于主句动作发生，像在told，said，knew，heard，thought等动词后的宾语从句中。
She said that she had seen the film before. 她说她以前看过这部电影。
4. 在表示过去概念的句子中，常出现与完成时态连用的词，如：already，yet，since，for，ever，never及表次数的词，此时句子常用过去完成时。
I met Jim in the street yesterday. We hadn’t seen each other since he went to Beijing. 我昨天在街上碰见了吉姆。自从他去北京后，我们彼此没有见过面。
【易混辨析】
过去完成时与现在完成时的区别
过去完成时与现在完成时的主要区别是时间的参照点不同：过去完成时的时间参照点是某个＂过去的＂时间；现在完成时的时间参照点是＂现在＂。因此现在完成时中的很多规则，也适用于过去完成时。
When I got to the cinema, the film had been on for five minutes. 当我到达电影院时，电影已演了五分钟了。 (got是一个过去的＂时间点＂，电影＂开始＂在我＂到达＂之前，是＂过去的过去＂。因为for five minutes为延续一段的时间状语，应用可延续的系表结构be on的过去完成时形式。）
【温馨提示】
过去完成时是一个相对的时态，表示的是＂过去的过去＂，只有在和过去某时或某动作相比较时才用到它，因此当原句中若找不到一个＂过去的时间＂作为参照点时，是不能用过去完成时的。
He got to the railway station and suddenly realized that he had forgotten to bring his ticket. 他到了火车站后忽然意识到他竟忘记带车票了。（＂忘记＂这一动作在＂意识到＂这一动作之前。）
By the time my parents reached home yesterday, I ____________ the dinner already.
A had cooked B. cooked C. have cooked D. was cooked

In the 3 term, there came a new humorous history teacher. I still had no passion for history. One day, she said: ＂We’ll have a test in the afternoon ＂. Since I wasn’t good at history, whenever I 4 a history examination, I had to cheat .At that noon, I made lots of cheat sheets quickly.
In the afternoon, I entered the classroom confidently. Soon my history teacher came in, along with our geography teacher. They both wore mysterious smile on their 5 . When the paper was 6 out finally, all of us found it was just a piece of geography paper. I became as 7 as a wooden chick at once. Just then, our teachers couldn’t help 8 loudly, which is just like a slap hitting on my face. I only got 12 points that time.
