t.(否定)
二、用法:
现在完成时既涉及过去,又联系现在
(一)表示过去发生或已经完成的动作对现在造成的影响或结果,也可表示过去已经开始,一直延续到现在的动作或状态
常与just(刚刚),already(已经),never(从来没有),ever(曾经),before(以前),yet(仍然,还),once(一次),twice(两次),manytimes(很多次),howmanytimes(多少次),sofar(迄今为止),uptonow,tillnow等时间状语连用。
如:
※副词的位置:
①just常用于肯定句中,放在have/has后,Hehasjustcome.
②never表示否定,放在have/has后,HehasnevervisitedtheGreatWall.
③ever用于疑问句中,句型为:
Have/Has+主语+ever+过去分词?
“…曾经……过吗?
”用于询问某人过去的经历。
Haveyoueverbeentothefarm?
④before用于句末,Thewomanhasneverheardofthatbefore.
⑤yet用于句末或not之后.Hasthetrainarrivedyet?
No,notyet.
⑥already用于肯定句,have/has之后或句末.Wehavealreadyfinishedit.
⑦sofar用于句首或句末.Sofar,wehavevisitedthemoon.
(二):
表示过去已经开始,一直延续到现在的动作或状态。
时间状语有:
①for+表示一段时间的词语IhavetaughtEnglishfor19years。
②since+表示过去时间点的词语Hehasbeenatthisschoolsince1986.
③since+表示过去的时间状语从句IhavelivedheresinceIwasborn.
④since+一段时间+ago.Ihaveknownhimsince20yearsago.
三、现在完成时态中可以和表示一段时间状语(for,since,howlong,allone’slife)连用的动词必须用延续性动词(肯定句)。
be,have,know,live,work,study,learn,teach,keep,speak,talk,draw,wait,wear,walk,sleep,drive,write,do,clean等。
Eg.Ihavebeenateacherfornearly20years.Howlonghashelivedhere?
常见终止性动词和延续性动词的相应转换形式如下:
1、borrow/lend→keep,2、buy→have,3、finish/end→beover,
4、begin/start→beon5、open→beopen6、close→beclosed,7、die→bedead
8、arrive/come/go/move/reach/getto→bein/at/behere/bethere,
9、leave→beaway(from)10、gotoschool→beinschool/beastudent,
11、getup→beup,12、fallasleep→beasleep13、fallill→beill
14、gettoknow→know,15、lose→belost16、become→be17、begintostudy→study,
18、return/comeback/getback→beback19、join→bein/bea…member,
20、jointhearmy→beinthearmy/beasoldier
21、receive/getaletter→havealetter22、catch/getacold→haveacold
Eg.他参军已有三年.Hehasjoinedthearmyforthreeyears.(错)改为:
Hehasbeeninthearmyforthreeyears/sincethreeyearsago.
Hehasbeenasoldierforthreeyears/sincethreeyearsago.
四、现在完成时中应注意的几个问题
1.havebeento和havegoneto的区
havebeento强调“曾经去过…”,现已不在那里,已经回来了
havegoneto主要强调的是“去了…”,可能在去的途中,或在去的目的地。
2.havebeento和havebeenin的区别
havebeento强调人“已回到原地”,后面可接表示“次数”的状语。
havebeenin表示某人“已在某地停留一段时间,现仍在那里”,其后常带表示一段时间的状语
