20、动作.We have had four texts this semester.6.现在完成时的完成用法 现在完成时的完成用法指的是动作发生在过去某一时刻并已结束,但该动作对现在产生了影响,与现在情况具有因果关系。例如:He has turned off the light.他已把灯关了。(动作结束于过去,但说明的是现在的情况-灯现在不亮了。)现在完成时完成用法的特点是动作不延续,因此,该时态只能与表示不定的过去时间状语(如:already,yet,before,recently 等)、频度时间状语(如:never,ever,once 等)、包括现在时刻在内的时间状语(如:this morni
21、ng month year.,today 等)连用。例如:Have you found your pen yet?你已找到你的钢笔了吗?7.现在完成时的未完成用法 现在完成时的未完成用法指的是动作开始于过去某一时刻,一直延续到现在,或可能还要继续下去。例如:He has lived here since 1978.自从 1978 年以来,他一直住在这儿。(动作起始于 1978 年,一直住到现在,可能还要继续住下去。)I have been in the army for more than 5 years.我在部队已经呆了五年多了。(动作开始于 5 年前,一直延续至今,有可能还要继续下去。)此

23、的时间一直延续到现在.)Up to/till now hes read many story books.至今他已读过好多故事书。Ive been to New York three times so far.至今我已到纽约去过三次。10 has gone(to),has been(to),has been(in)的区别 gone:去了没回 been to:去过 been in:呆了很久 11.不能与 when 连用 一般过去时和现在完成时 (1)、一般过去时的谓语动词用过去式,而现在完成时的谓语基本构成是“主语+have/has+动词(V.)的过去分词”。过去时表示过去某时发生的动作或单纯叙
24、述过去的事情,强调动作;现在完成时为过去发生的,强调过去的事情对现在的影响,强调的是影响。(2)、一般过去时通常与表示过去的时间状语连用。如:yesterday,last week,two years ago,just now,in 2002 等;而现在完成时则常与 just,already,ever,never 等副词和 these days,this week,since.,for.等表示一段时间的状语连用。试比较以下几组句子,有什么区别:A:Have you seen the film?B:Did you see the film?分析:你看过这部电影吗?(A)句强调的是被问者对剧情是否
25、了解;(B)句强调的是看这部电影的动作是否发生过,并不强调是否知道其内容。A:How has he done it?B:How did he do it?分析:他是怎么做的这件事?(A)句强调的是他做这件事的方式对现在产生了某种影响;(B)句单纯的询问做这件事的方式。A:He has lived in Beijing for 8 years.B:He lived in Beijing for 8 years.分析:他在北京住了 8 年。(A)句讲的是到目前为止他在北京住了 8 年,可能还会继续在北京住下去。(B)句讲的是他在北京住过 8 年,现在已经不在北京了。(3)现在完成时强调过去发生的动
