17、规则变形两种,规则动词的过去分词的变形与该动词过去式的变形相同。时间状语常与already, just, yet, lately, recently, never, ever, once, twice, three times, before等连用。用法1. 表示结束、结果。动作发生在过去,而且终止于过去,但其结果对现在仍有影响。如:Ive written down some ideas. 我已经写下了一些想法。Ive just finished my homework. 我刚刚完成了我的作业。2. 表示继续。动作或状态从过去某一时刻开始,一直持续到现在,并有可能延续下去,要用持续性动词(否定

20、果是短暂性动词,通常不能与表示一段时间的for短语及since短语(或从句)等连用。应将短暂性动词改为相应的延续性动词。转换情况如下:borrowkeep, buyhave, diebe dead, come (to)be (in), go/leavebe away, becomebe, fall asleepbe asleep, beginbe on, go outbe out, joinbe a member of, marrybe married。如:He has been away since last week. 自从上周他就离开了。How long have you kept th

22、到上海去了。(玛丽已不在出发地了)现在完成时与一般过去时的区别侧重点不同。现在完成时是与现在有关的状态,属现在时态范畴,它侧重于过去的动作对现在造成的影响;而一般过去时是一种过去时态,侧重于表示过去的动作,与现在无关。如:I closed the door five minutes ago. 我五分钟前关上了门。(强调动作发生在过去,现在门是否关上无从知晓)I have closed the door. 我已经关上了门。(强调门现在是关着的)八、过去完成时构成助动词had+动词的过去分词。用法1. 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。它表示动作发生的时间是“过去的过去

23、”。常与by, before, by the end of, by the time (that)等引导的时间状语从句连用。如:She had known my brother for three years before I met her. 在我见到她以前,她认识我哥哥已经3年了。By 10:30 she still hadnt arrived. 到10:30时她还没到。I found the letter after he had gone away. 他走了以后我找到了那封信。2. 过去完成时常用于宾语从句中。主句谓语为过去式(said, asked, told等),从句用过去完成时,

24、此时从句中的动作发生在主句的动作之前。如:She said she had worked in a foreign company for five years before she became an English teacher. 她说在成为一名英语教师之前她已在一家外国公司工作了5年。【活学活用】 用所给动词的适当形式填空。1. Uncle Wang is the funniest person I_ ever _(meet).2. When he asked me about my homework yesterday, I _ already_ (hand) it in.3. Ch
