be,come,become,buy,can,do,eat,feel,go,give,hear,know,let,see,write
(二)Definition
1.已完成用法,也叫影响性用法。
该用法的现在完成时表示一个过去发生的动作在过去已经完成,但对现在产生影响。
2.未完成用法,也叫持续性用法。
该用法的现在完成时表示一个过去发生的动作或开始的状语在过去并未完成或结束,而是一直持续到现在,并且有可能继续下去(也可能到此结束)。
(3)Structure
Have/has+过去分词
回顾句子结构:
(定)主(状)谓(定)宾(补)
E.g,Hehasseenthefilmseveraltimes.这部电影他已经看了好几次了。
(已完成)
E.g.Ihaveknownherforalingtime.我认识她很长时间了。
(未完成)
否定句:
主语+have/has+not+过去分词+其他
一般疑问句:
have/has+not+主语+过去分词+其他
(4)常用时间状语:
“since+时间”,“for+时间段”及howlong,since,ever,never,already,yet,twice,sofar,uptonow,overtheyears,inthelast/pastfewyears.
1.Since表示“自从......以来”时,无论是用作介词、连词还是副词,since通常要与现在完成时连用。
如:
I’vehadnothingtoeatsincelunchtime.从中午到现在我什么都没吃。
IthasbeenalongtimesincetheTFboysfounded.TFboys成立很久了。
Ithastenyearssincehelefthere.他离开这儿已10年了。
2.Inthelastfewyears/inthepastfewyears,“在过去的几年”表示从现在算起的过去一段时间内,通常要与现在完成时连用。
如:
Thehousehaschangedhandsthreetimesinthelasttwoyears.在过去的两年中,这栋房子已转手三次。
I’veseenlittleofherinthepastfewweeks.近几周我很少见到她。
3.Overtheyears“这些年来”“经过这么多年之后”“最近几年”,通常表示从现在算起的过去几年。
She’sbroughtussomuchhappinessovertheyears.这些年来,她给我们带来了不少的幸福。
4.Sofar/Uptonow“到目前为止”
Sofar/Uptonow500peoplehavediedintheearthquake.到现在为止,已有500人在地震中丧生。
5.It’sthefirsttimethat...“这是第一次做某事”,that从句后跟现在完成时。
如:
It’sthesecondtimeI’vecomehere.这是我第二次来这。
(forsb.)todosth.
It’stime用动词的过去式(be用were)
(that)
用should+动词原形(should不省略)
It’stimetodocleaning.
It’stimeweshoulddocleaning.
It’stimewedidcleaning.
注意:
1.现在完成时不能单独与过去的时间状语连用,如yesterday,lastweek,threeyearsago等;2.不能与when连用;3.现在完成时往往同表示不确定的过去时间状语连用。
(5)hasgoneto,hasbeento,hasbeenin的区别
Have/hasgoneto:
去了(现在不在现场)
Whereisyourfather?
HehasgonetoShanghai.
Have/hasbeento:
去过(在现场)
MyfatherhasbeeninShanghai.
Havebeenin:
待了多久(还在所待的地方)
MyfatherhasbeeninShanghaifortwomonths./sincetwomonthsago.
注意:
与表示次数的once,twice,threetimes等连用是,只能用Havebeento.
ShehasbeentoEuropetwice.他到欧洲去过两次。
另外,havebeento除了可接地点表示去过某地外,有时可以接活动,表示去参加过某种活动,或接动词原形(尤其是动词see),表示去做某事。
如:
She’sjustbeentoaparty.她刚参加了晚会回来。
HehasneverbeentoseemesinceIhavebeenill.我生病以来他从未来看过我。
(6)现在完成时的肯定句中瞬间动词(buy,die,join,come,goleave,join...)不能直接与for+时间段,since+时间点连用。
要将其改为延续性动词。
口诀:
开始离去,借来还,出生入死,买到家。
+开关结束

Begin--beongoout---beoutborrow--keepcome/arrive/reach/join----beinReturn--comebackto
