七、现在完成时
时间状语:recently, lately, since…for…,in the past few years, etc.
动词过去分词的构成:
动词过去分词的规则变化与过去式的规则变化相同;不规则变化的需要我们单独记忆,记住常见动词的过去分词,例如:
do see ( http: / / www.21cnjy.com ) say hear go have sleep find get cut put eat buy come
read spend ( http: / / www.21cnjy.com ) pay think bring tell
现在完成时的用法:
1.表示过去发生或已经完 ( http: / / www.21cnjy.com )成的动作对现在造成的影响或结果,常与already, yet, ever, never, just,before 等词连用。
You have already grown much taller.
2、表示过去已经开始,持续到现在的动作或状态,并可能还要延续。往往和表示一段时间的时间状语连用,常用的有:for+一段时间;since+过去时间点或从句。(Since 用来说明动作起始时间,for用来说明动作延续时间长度),提问用How long.
It has been five years since he joined the army .
They have learned English for nine years .
3、现在完成时需注意的问题:
1)表示短暂性的动词(瞬间动词)不能与表示一段时间的状语连用
注意:非延续性动词(瞬间动词)的否定形式可以与表示延续时间的状语连用。即动
作不发生的状态是可以持续的。
(错)I have received his letter for a month.
(对)I haven't received his letter for almost a month.
2)不能和明确的过去时间状语连用,如:yesterday, last week, in 1998,two days ago等。
3)have/has been to 和have/has gone to 的区别:
have/ha ( http: / / www.21cnjy.com )s been to have/has gone to
4)比较一般过去时与现在完成时
一般过去时表示过去某时发生的动作或状态,强调动作,不和现在发生
联系,常与具体的过去时间状语连用,如yesterday, last week,…ago, in 1980, in October, just now等,;现在完成时表示过去发生的某一动作对现在造成的影响或结果,强调的是现在的情况,不能与表过去的时间状语连用。
I saw this film yesterday. (强调看的动作发生过了)
I have seen this film. (强调对现在的影响,电影的内容已经知道了)
Why did you get up so early (强调起床的动作已发生过了)
He has been a League member for three years. (强调他是团员)
练习:1. You have _____ a tall young man. A. grown B. grown into C. grew D. grown up
2. He has ____ the watch for a year. A .buy B. bought C. have D. had
3. I _____this book for two weeks, I have to return it now.
A. borrowed B. have borrowed C. kept D. have kept
4. Have you ever ( http: / / www.21cnjy.com )_____to the Great Wall It's very beautiful. A. gone B. been C. went D. go
5. Her brother _____the Party since 1978. A. joined B. has joined C. has been in D. was in
6. The Greens ___many places of interest since they came to China.
3) 有些动词表示无法持续的 ( http: / / www.21cnjy.com )动作,它们一般不宜用于进行时态中。这类动词常见的有:be , believe , consist , find , forget , hate , have , hope , hear , know , like , love , notice , prefer , remember , see , seem , smell , suggest , taste , understand , want , wish , sit down , stand up 等等。
Be动词若是用于进行时态,可表示暂时、短暂的情况或表现。例如:
Tom is being a good boy today .汤姆今天很乖。
He is being childish .他这样做是耍孩子气。
You are not being modest .你这样说不太谦虚。
4)关于现在完成时的时间状语问题
A. 凡是"完成时态"都表示,不知 ( http: / / www.21cnjy.com )道也不管动作发生的具体时间, 所以在使用现在完成时的句子里,不可以带有表示具体过去时间的状语,如:yesterday , last week ( month , year , etc. ) , two weeks ago , in 1999等;但常和有些副词连用,如: just , before , already , often , never , ever , not…yet , always等等。
B. 在以when提问的特殊疑问中不 ( http: / / www.21cnjy.com )能用现在完成时。另外,ago不能用于现在完成时的句子里,因为它表示从现在算起的以前某个时间,属于表示具体过去时间的状语。但是可以用before 来表示"以前"的意义,因为它只表示"以前",而不知什么时候的以前。
C. 如果是不表示连续性 ( http: / / www.21cnjy.com )的动词用于现在完成时的句子,不可以和以for表示的"一段时间"的状语连用。在这种情况下,应该用"It has been … ;since…"的句式来表达。如:
He has joined the army for five years. (错误)
It has been five years since he joined the army.(正确)
特殊用法(现在完成时用法之常用词语)
1. 在下列5种情形下用现在完成时态
1十一词语
①already已经 肯 ( http: / / www.21cnjy.com )定句中或句尾例: I have already found my pen. = I have found my pen already.
②yet已经 否定句和疑问句句尾 例:I have not finished the work yet.
Have you bought a computer yet
③ever曾经 句中 例:Have you ever seen pandas
④never从不 句中 例:I have never been to Beijing.
⑤just刚刚 句中 例:I have just done my work.
⑥before以前 句尾 例:I have never been there before.
⑦so far到目前为止 例:So far he has learnt 200 words.
⑧how long多久 例:How long have you lived here
⑨how many times多少次 例:How many times has he been to Beijing
⑩in the past … years(在过去…年中):
In the past two years I’ve seen him little. 过去两年我很少见到他。
I have been here (for) the last month. 最近一个月里我都在这儿。
【注】在一定的上下文里,若是以过去时间为起点,也可用过去完成时。
11 up to now(到现在为止):
I have heard nothing from him up to now. 到现在为止我还没有听到他一点音信。
12It’s the first time that…(第一次…):
It’s the first time I’ve come here. 这是我第一次来这儿。
2两词组

havebeen to去过某地 例:He has been to Beijing. (去过北京)
3两结构
for two months for +一段时间 Jim has lived here for 2 months.
since last year since +过去的点时间 Lucy has been in Beijing since 3 years ago.
since 3 years ago
since 1990
since he came here since +一般过去态句子 He has been in China since he came here.
4如果句子里面没有时间状语,汉语意思能够加“已经”,往往用现在完成时态。
例:Have you lost your library book 你已经弄丢了从图书馆借的那本书吗?
5现在完成时态还常常用于下列句型
They have planted ( http: / / www.21cnjy.com )many trees in the last few years. 在过去的几年,他们已经种了很多树。
This is the best book I have ever read. 这是我曾经读过的最好的一本书。
It is the first time I have played the computer games. 这是我第一次玩电脑游戏。
2. 重难点,必考 在现在完成时中,一次性动词不能和一段时间状语连用
例:He has bought the book for 3 years.(错)
因buy这个一次性动词不能和一段时间for 3 years连用, 改正的办法有五种:第五种改法必考
① He has bought the book.. (去掉一段时间for 3 years)
② He bought the book 3 years ago (改为一般过去时,使句子的意思不变)
③ It’s 3 years sin ( http: / / www.21cnjy.com )ce he bought the book. = 3 years has passed since he bought the book.
(改为固定句型 It is ---since---)
④ He has not bought the book for 3 years. (改为否定句)
⑤ He has had the book for 3 years. (用延续性动词have代替一次性动词buy)
3. 还有其他一次性动词也是这种情况,可参照前面的五种办法改正,前四种改法都一样,第五种改法各不相同,举例如下:
①come/arrive/get to/reach 改为 be here
例:I have come here ( http: / / www.21cnjy.com ) for 3 years.(错) 改为:I have been here for 3 years.
②leave/go改为be away
例:He has left for 3 hours.(错) 改为:He has been away for 3 hours.
③begin/start改为be on
例:The film has ( http: / / www.21cnjy.com )begun for 3 minutes.(错) 改为:The film has been on for 3 minutes.
④open改为be open / close改为be closed
例:The shop h ( http: / / www.21cnjy.com )as opened for 3 years.(错) 改为:The shop has been open for 3 years.
⑤die改为be dead
例:His father has ( http: / / www.21cnjy.com ) died for 3 years.(错) 改为:His father has been dead for 3 years.
⑥finish/end改为be over
例:He has fini ( http: / / www.21cnjy.com )shed the work for 3 days.(错) 改为:The work has been over for 3 days
⑦join 例:I have joined the army for 3 years.(错)
改为:I have been ( http: / / www.21cnjy.com )in the army for 3 years. 或I have been a soldier for 3 years.
⑧buy /catch改为 have
例:I have bought the ( http: / / www.21cnjy.com )bike for 3 years.(错) 改为:I have had the bike for 3 years.
例:He has ca ( http: / / www.21cnjy.com )ught a cold for 3 days.(错) 改为:He has had a cold for 3 days.
⑨borrow改为keep
例:I have borrowed the ( http: / / www.21cnjy.com ) book for 3 years. (错) 改为:I have kept the book for 3 years.
其它补充如下:break改为b ( http: / / www.21cnjy.com )e broken \ get up改为be up \marry改为be married \ become改为be \ lose改为be lost
4. 延续性动词和终止性动词
①延续性动词:表示的动作是能延续的动作,这种动作可以延续下去或产生持久的影响。
如:learn\ work\ stand ( http: / / www.21cnjy.com )\ lie\ know\ walk\ keep\ have\ wait\ watch\ sing\ read\ sleep\ live
②终止性动词:也叫非延续性动词, ( http: / / www.21cnjy.com )瞬间动词,一次性动词,短暂性动词。表示的动作不能延续,即动作发生后立即结束,产生某种结果。在有了某种结果后,动作就不能再继续下去。
如:leave\ star ( http: / / www.21cnjy.com )t\ set out\ arrive\ reach\ get to\ begin\ stop\ shut\ turn off\ marry\ put\ put on\ get up\ wake\ fall\ join\ meet\ receive\finish\ end\ complete\ become\ come\ go\ die\ open\ close\ break\ give\ jump\ buy\ borrow
5. 一次性动词不能和一段时间状语连用。
He has died for three days. (错,终止性动词die不能和一段时间for three days连用)

八、过去完成时
一、过去完成时的判断依据
1. 由时间状语来判定
一般说来,各种时态都有特定的时间状语。与过去完成时连用的时间状语有:
( 1 ) by + 过去的时间点。
如: I had finished reading the novel by nine o'clock last night.
( 2 ) by the end of + 过去的时间点。
如: We had learned o ( http: / / www.21cnjy.com )ver two thousand English words by the end of last term.
( 3 ) before + 过去的时间点。
如: They had planted six hundred trees before last Wednesday.
2. 由"过去的过去"来判定。
过去完成时表示"过去的过 ( http: / / www.21cnjy.com )去",是指过去某一动作之前已经发生或完成的动作,即动作有先后关系,动作在前的用过去完成时,在后的用一般过去时。这种用法常出现在:
( 1 )宾语从句中
当宾语从句的主句为一 ( http: / / www.21cnjy.com )般过去时,且从句的动作先于主句的动作时,从句要用过去完成时。在told, said, knew, heard, thought等动词后的宾语从句。如:
She said that she had seen the film before.
( 2 )状语从句中
在时间、条件、原因、方式等状语从句中,主、从句的动作发生有先后关系,动作在前的,要用过去完成时,动作在后的要用一般过去时。如:
When I got to the station, the train had already left.
After he had finished his homework, he went to bed.
注意: before ( http: / / www.21cnjy.com ), after 引导的时间状语从句中,由于 before 和 after 本身已表达了动作的先后关系,若主、从句表示的动作紧密相连,则主、从句都用一般过去时。如:
Where did you study before you came here
After he closed the door, he left the classroom.
( 3 )表示意向的动词,如hope, w ( http: / / www.21cnjy.com )ish, expect, think, intend, mean, suppose等,用过去完成时表示"原本…,未能…" We had hoped that you would come, but you didn't.
3. 根据上、下文来判定。
I met Wang Tao in t ( http: / / www.21cnjy.com )he street yesterday. We hadn't seen each other since he went to Beijing.
三、过去完成时的主要用法
1. 过去完成时表示一个动作或状态在过去某一时间或动作之前已经完成或结束,即发生在"过去的过去"。如:
When I woke up ( http: / / www.21cnjy.com ), it had stopped raining. 我醒来时,雨已经停了。(主句的动作发生在"过去的过去")
2. 过去完成时是一个相对的时态,表示的是"过去的过去",只有和过去某一时间或某一动作相比较时才使用它。如:
He told me that he had written a new book. (had written 发生在 told 之前 )
3. 过去完成时需要与一个表示过去的时间状 ( http: / / www.21cnjy.com )语连用,它不能离开过去时间而独立存在。此时多与 already , yet , still , just , before , never 等时间副词及 by , before , until 等引导的短语或从句连用。
如:Before she came to China, Grace had taught English in a middle school for about five years.
Peter had collected more than 300 Chinese stamps by the time he was ten.
4. 过去完成时表示某一动作或状态在过去某时之前已经开始,一直延续到这一过去时间,而且动作尚未结束,仍然有继续下去的可能。
如: By the end of l ( http: / / www.21cnjy.com )ast year, he had worked in the factory for twenty years. ( had worked 已有了 20 年,还有继续进行下去的可能)
A. did, do B. has, done C did, did. D. had, done
3. I ______ 900 English words by the time I was ten。
A. learned B. was learning C. had learned D. learnt
4. She ______lived here for ______ years.

9. She had written a number of books ______ the end of last year.
A. for B. in C. by D. at
10. He _____ to play ____ before he was 11 years old.
A had learned, pia ( http: / / www.21cnjy.com )no B. had learned, the piano C. has learned, the piano D. learns ,piano.
