1、Unit 12 语法篇_第十二单元重点单词和句型一、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”。二、过去完成时的构成过去完成时是由“助动词had+动词的过去分词”构成，had用于各种人称和数。如：She had arrived at the village before 8 oclock last night.她在昨晚8点之前就到达了这个村庄。三、过去完成时的句式过去完成时的否定句是在had后加not，一般疑问句是将had移至句首，其肯定回答为:Yes，主语+had，否定回答为：No,主语+hadnt。如：Her little brother
2、hadnt gone into the bathroom by the time she got up.当她起床时，她弟弟还没有进入浴室。Had you started teaching when she got to the class?当她走进教室时，你开始讲课了吗？Yes,I had.是的，我开始讲了。(No,I hadnt.不，我还没有讲。)四、过去完成时的标志1.用于表示过去某一时刻前已经发生的动作或状态。常与by,before,after,until,when等引导的过去时间状语连用。如：They had collected over 1,000 stamps by the end
3、 of last month.到上个月底，他们已收集了1,000多张邮票。The bus had already left by the time I got outside.当我出去时，公共汽车已经开走了。提示：如果时间状语从句的动作发生在主句之前，则从句用过去完成时，主句用一般过去时。如：My watch went well after Id had it repaired.我的手表修了以后，走得很准。2.过去完成时用于宾语从句中，表示从句的动作或状态发生在主句的谓语动作之前。如：He told me that he had heard of the good news.他告诉我，他已经听
4、说了那个好消息。提示：有时过去完成时也用在其他从句中。如：What he had said made me angry.他说的话让我生气。(用于主语从句中)3.有时句子中没有明显的时间状语，动作发生的时间先后，需从上下文中去判断。如：She was very happy.Her whole family were pleased with her,too.She had just won the first place in the game.她非常高兴，她的全家人也为她高兴。她刚刚在比赛中获得第一名。五、过去完成时的持续用法表示过去某一时间之前发生的动作或存在的状态一直持续到过去某一时间，并
5、有可能继续下去。常与由for或since引导的表示一段时间的短语或从句连用。如：He had worked in the factory since it opened in 1996.自从1996年工厂建成以，来他一直在那儿工作。Mr.Smith had taught in Europe for 15 years before he went to Australia.史密斯先生在去澳大利亚之前在欧洲从教了15年。六、过去完成时与一般过去时的区别1.过去完成时表示过去某一时间或某个动作之前已经发生的动作或存在的状态。它是个相对的时态，只有在与过去某一时间或某一动作相比较时才会用到它。而一般过
6、去时则表示过去某一个时间发生了某事或在过去某一段时间内经常发生的事。如：They had already left when I arrived.我到达时他们已经走了。(在我“到达”这一过去动作之前，他们就已经“离开”了，因此用had left表示。)I saw him in the street yesterday.昨天我在街上看见他了。(“看见他”这一动作是在“昨天”这一过去的时间发生的)2.在过去某时之前的持续动作，表示某事持续到过去某时已有一段时间，则用过去完成时，并与for，since等词连用。如：He had been ill for a week when he was sent
7、 to the hospital.他被送到医院时已病了一周了。He said that he had worked in that factory since 1994.他说他从1994年以来就一直在那家工厂工作。3.在并列句或复合句中，几个(一般是两个)谓语动词的行为发生的顺序有明显的先后之分时，则先发生的行为用过去完成时。但若句中有before,after等连词，由于它已表明动作发生的先后，两个动作都可以用一般过去时。如：When I woke up,it had already stopped snowing.我醒来时雪已停了。I (had) heard the news before
8、she told me她告诉我那个消息之前我已经听说了。After we finished our homework，we went swimming.做完作业后，我们去游泳了。4.两个或两个以上的动作，用and，then或but等连接，按照动作发生的顺序表达时，用一般过去时，表示过去发生的连续动作。如：The man got up,put on his cap and went away.那个人站了起来，戴上帽子走了。【拓展】动词think，hope，want，mean，intend，plan等可以用过去完成时来表示过去未曾实现的想法、愿望、打算或意图等。如：We had hoped to
9、be able to come and see you我们本来希望能来看看你。They had wanted to help but could not get there in time.他们本来打算去帮忙，但没能及时赶到那里。七、过去完成时与现在完成时的区别过去完成时与already,ever,just,never,since+时间点，for+时间段等连用时，强调事件发生的先后顺序，不涉及现在的情况。而现在完成时强调的是“过去的动作或状态对现在造成的影响”。如：She has worked in Chongqing for over two years.她已经在重庆工作两年多了。(现在仍在
10、那儿工作)She had worked in Chongqing for over two years before she moved to Shanghai.她在搬到上海之前已经在重庆工作两年多了。(“搬到上海”是过去，“在重庆工作”是发生在过去的过去)He has never seen such an interesting film before.他以前从未看过这么有趣的电影。(“看”尽管发生在过去，但涉及现在，即现在已经知道或了解了这部电影)He said he had never seen such an interesting film before.他说他以前从没看过这么有趣的
