Ihaveseenthefilm.→Haveyouseenthefilm？

Yes,Ihave./No,Ihaven’t.

三、两种基本用法

1.“过去的经历”：

动作发生在过去的某一时刻且已经结束，但未说明动作发生的具体时间或情景，强调该经历（即动作发生后）对现在所造成的影响或产生的结果。

如：

Ihaveheardoftheman.（表示我对这个人有一定的了解）

2.“完成情况”：

表示过去已经开始并持续到现在的动作或状态，或有可能继续延续下去。

句子中一般有说明其完成情况的短语或从句。

①句子中有“已发生了多久”的时间状语的短语或从句。

IhavelivedinShanghaisinceIwastenyearsold.

②说明“到说话时为止，已完成了多少”。

句中含有表示“完成了多少”的宾语或表示动作发生次数的状语。

Ihavereadthebookthreetimes.

Ihaven’tseenthefilmsofar.

四、一般过去时与现在完成时的区别

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，强调动作；

现在完成时表示过去发生的，强调过去的事情对现在的影响，强调的是影响。

Isawthisfilmyesterday.　　（强调看的动作发生过了。

）

Ihaveseenthisfilm.　　（强调对现在的影响，电影的内容已经知道了。

2）一般过去时常与具体的表示过去的时间状语连用;

如：

yesterday,lastweek，…ago,in1990,inOctober,justnow

现在完成时常与模糊的时间状语连用，或无时间状语。

for,since,sofar,ever,never,just,yet,till/until,inthepastfewyears,recently等

句中有过去时的时间副词（如yesterday,last,ago,in1960）时，不用现在完成时，要用过去时

　（错）Tomhaswrittenalettertohisparentslastnight.

　（对）Tomwrotealettertohisparentslastnight.

3）一般过去时常用的非持续性动词有come,go,leave,start,die,finish,become,getmarried等；

现在完成时表示持续到现在的动作/状态，动词一般是延续性的live,teach,learn,work,study等

ShejoinedtheLeaguethreeyearsago.

ShehasbeenintheLeagueforthreeyears（sincethreeyearsago）.

ShehasbeenaLeaguememberforthreeyears（sincethreeyearsago）.

五、延续动词与瞬间动词 

延续动词表示经验、经历；

通常后面接“时间段”；

瞬间动词表示行为的结果，不能与表示一段时间的状语连用。

延续动词与非延续动词的转换

延续性动词表示能够延续的动作，如：

learn,work,walk,keep,have,wait,watch,sing,read,sleep,live,stay等。

表示时间段的短语有:

for+一段时间：

for2years,foralongtime;

since从句：

sincehecamehere;

since+时间点名词：

sincelastyear,since5daysago;

howlong

非延续性动词也称终止性动词、瞬间动词，表示不能延续的动作，这种动作发生后立即结束。

open,die,close,begin,finish,come,go,move,borrow,lend,buy等。

HehascometoChina.=HehasbeeninChinafortwoweeks.

Theoldmandied4yearsago. 

=Theoldmanhasbeendeadfor4years. 

HejoinedtheParty2yearsago. 

=HehasbeeninthePartyfor2years. 

六、比较since和for

since用来说明动作起始时间，“自从……”　　

IhavelivedheresinceIwasborn.

　　Myaunthasworkedinacompanysince1949.

for用来说明动作延续时间长度—“长达……”

Ihavelivedhereformorethantwentyyears.

Ihavenotheardfrommyuncleforalongtime.

比较have/hasbeentohave/hasgonetohave/hasbeenin

HehasbeentoShanghai.他（曾经）到/去过上海（去了已回）

HehasgonetoShanghai.他已经去上海了（去了未回）

HehasbeeninShanghaifor10years.他呆在上海迄今为止已经10年了（现在还在上海）
