过去完成时态教案

过去完成时态 一、概念:过去完成时表示在过去某一时间或动作之前已经发生或完成了的动作或呈现的状态, 即“过去的过去(past-in-the-past )”。 二、构成:过去完成时由“助动词had + 过去分词”构成,其中had 通用于各种人称。 e.g. They had already had breakfast before they arrived at the hotel. She had finished writing the composition by 10 :00 this morning. 三、句式:它的否定句是在had后边加not,变一般疑问句是把had提前。 肯定答语:Yes, 主语+had 否定答语:No,主语+hadn’t e.g. I had reached the station before 9:00 o'clock. I had not reached the station before 9:00 o'clock. Had you reached the station before 9:00 o'clock? Yes, I had. No, I hadn’t. 四、用法: 1. 过去完成时表示一个动作或状态在过去某一时间或动作之前已经完成或结束,即发生在“过去的过去”。如:When I woke up, it had stopped raining. 我醒来时,雨已经停了。(主句的动作发生在“过去的过去”) 2. 过去完成时是一个相对的时态,表示的是“过去的过去”,只有和过去某一时间或某一动作相比较时才使用 它。如:He told me that he had written a new book. (had written 发生在told 之前) 3. 过去完成时需要与一个表示过去的时间状语连用,它不能离开过去时间而独立存在。此时多与already ,yet ,still ,just ,before ,never 等时间副词及by ,before ,until 等引导的短语或从句连用。如:Before she came to China, Grace had taught English in a middle school for about five years. Peter had collected more than 300 Chinese stamps by the time he was ten. 4. 过去完成时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) 五、过去完成时的判断依据 1. 由时间状语来判定 一般说来,各种时态都有特定的时间状语。与过去完成时连用的时间状语有: ( 1 )by + 过去的时间点。 如:I had finished reading the novel by nine o'clock last night. ( 2 )by the end of + 过去的时间点。 如:We had learned over two thousand English words by the end of last term. ( 3 )before + 过去的时间点。 如:They had planted six hundred trees before last Wednesday. 2. 由“过去的过去”来判定。 过去完成时表示“过去的过去”,是指过去某一动作之前已经发生或完成的动作,即动作有先后关系,动作在前 的用过去完成时,在后的用一般过去时。这种用法常出现在: ( 1 )宾语从句中 当宾语从句的主句为一般过去时,且从句的动作先于主句的动作时,从句要用过去完成时。在told, said, knew, heard, thought等动词后的宾语从句。如:She said that she had seen the film before. ( 2 )状语从句中 在时间、条件、原因、方式等状语从句中,主、从句的动作发生有先后关系,动作在前的,要用过去完成时,

英语计划总结之现在完成时用法小结

英语计划总结之现在完成时用法小结 现在完成时是中学生必须掌握的重要语法项目之一,也是难点之一,要想让学生灵活掌握这一要点,必须对其用法进行深析和加强实际运用. 一、现在完成时的构成 现在完成时是由“have/has+动词的过去分词”构成.其中的have/has在这里只充当助动词,故将肯定式变成否定式时直接在其后面加not,变成疑问句时直接将其提前. 二、现在完成时的含义 表示过去发生或已经完成的某个动作对现在所造成的影响或结果,重在与现在的联系.如: I have finished my homework already. He has never been to England. 2. 表示动作或状态从过去某时开始,一直持续到现在,并有可能会持续下去.如: I have lived here for ten years. I have lived here since ten years ago. 三、运用现在完成时的几个注意点 1. 熟记与现在完成时连用的时间状语.

already,yet,before, ever, never, before, recently, just, many times, until now, up till now, so far, since 2000, for ten years, in the past/last five years, these days等. 2. 注意现在完成时与一般过去时的区别. 一般过去时只是单纯地表示过去的动作或状态,和现在不发生联系,它要和表示过去的时间状语连用.而现在完成时表示的是过去的某一动作对现在造成的影响或结果.强调的是现在的情况,它不能和表示过去的时间状语连用.两种时态的侧重点不同,前者强调的是动作本身,后者则强调结果.比较: I lost my watch yesterday.(至于现在找到与否没有说明,即不跟现在发生联系) I have lost my watch…(表示现在的结果——手表未找到) 3. 当现在完成时与since,for引导的时间状语连用时,其谓语动词必须是延续性动词,如果是终止性动词,必须将其转换成延续性动词.如: I borrowed this book two days ago. I have kept this book for two days. I have kept this book since two days ago. 常见的终止性动词与延续性动词的转换有:become; come—be here; go—be there; begin—be on; open—be open; close—be close;
