辽宁省鞍山市汤岗子学校七年级上册英语教学课件：过去完成时-(共38张).pptVIP

4. 过去完成时可表示某一动作或状态在过去某时之前已经开始，一直延续到这一过去时间，而且动作尚未结束，仍然有继续下去的可能。如： By the end of last year, he had worked in the factory for twenty years. （ had worked 已有了 20 年，还有继续进行下去的可能） 6:00 7:00 现在 By the time I got up, my sister had already washed all the clothes. I got home now 9:00pm 8:00pm My little brother went to bed By the time I got home, my little brother had gone to bed. I got to school now 8:15 8:00am The teacher came into the classroom By the time I got to school, the teacher had come into the classroom. By the time she got outside, the bus had already left. 1. He ______ in Shanghai University for four years before he ______ to Beijing. A. studied, had gone??? B. had studied, went C. has studied, goes???? D. had studied, had gone 例题解析 解析：“他去北京之前在上海大学学习了4年 ”。在上海大学学习的动作发生在去北京之前，因此第一个空应用过去完成时。此题选B。 　 B 2. Mary said it was at least five years since she ______ a good drink. A. enjoyed???? B. was enjoying?? C. had enjoyed?? D. would enjoy 解析：“It was + 时间段+since 引导的从句”中用过去完成时。应选C。 C 3. Xiao Pei said she ______ Hainan for 3 months. has been in??? B. had been in?? C. had been to?? D. had gone to 解析：“小培说她在海南三个月了”。have been to 和have gone to 都是短暂性的动词短语，表示状态的应该用have been in， 故应选B。 B 过去完成时是一个相对的时态，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； 现在完成时表示的动作发生在过去，但侧重对现在产生的结果或造成的影响，与现在有关，其结构为“ have (has) + 过去分词”。 过去完成时与现在完成时的区别 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。 时间轴表示： 虽然这两种时态都表示过去发生的动作或存在的状态，但在使用时应注意以下几点：　 时间状语不同：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。 过去完成时与一般过去时的区别 试比较： They had arrived at the station by ten yesterday. They arrived at the station at ten yesterday. 2. 在没有明确的过去时间状语作标志时，谓语动词动作发生的时间先后须依据上下文来判断：先发生的用过去完成时，后发生的则用一般过去时。 3. 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，因此也可以用过去时来代替过去完成时。如： He entered the room, turned o
