1、现在完成时用法及综合练习一 . 现在完成时的 完成用法 姓名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 morning ,this month ,
2、this year.,today等)连用。例如:Have you found your pen yet ?你已找到你的钢笔了吗?二现在完成时与一般过去时的用法比较1.一般过去时表示过去某时发生的动作或单纯叙述过去的事情,强调的是过去的动作;现在完成时为过去发生的,强调过去的事情对现在的影响,强调的是现在的影响。例:I saw this film yesterday. (强调:是昨天看的)I have seen this film. (强调对现在的影响:电影的内容已经知道了)She has returned from Paris.她已从巴黎回来了。 (She is here.)She retur
3、ned yesterday. 她是昨天回来了。The plane has arrived . 飞机已经来了。(说明现在的情况:飞机在这儿)The plane arrived a quarter ago. 飞机是一刻中以前来的。(强调:动作发生的时间在过去)I have lost my pen.( 强调:我现在没有笔) I lost my pen.( 过去笔掉了,没说明现在是否有笔) 2.现在完成时不可和表过去的时间状语连用(before,just 等除外 ),但一般过去时可与表过去的时间状语,如yesterday,last week,three days ago,just now等连用。 如:
4、A:Hello,Kate!Have you had supper? B:Yes,I have. A:When did you have it?

7、 - 三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。此种用法的句中常需一个表示一段时间的时间 状语 (由 how long, since或 for 引导 ), 或表示与现在时刻相连的时间状语(如:these days,up to now,so far)等。例如:1.He has lived here since 1978. (动作起始于 1978 年,一直住到现在,可能还要继续住下去。) 2. I have taught here for 21 years.(表示二十一年前的动作一直延续到现在,还可能会继续。)3.She
