译林版高中英语必修2讲义Unit 1 Section Ⅲ Grammar——现在完成时和现在完成进行时

Section ⅢGrammar——现在完成时和现在完成进行时一、现在完成时1.现在完成时的用法(1)表示过去发生的动作产生的结果或对现在造成的影响。

动作虽然发生在过去,但落脚点在现在。

I've forgotten his telephone number.我忘记了他的电话号码。

(没法联系他了)I haven't finished reading this book yet,so I can't return it to the library.这本书我还没有看完,所以不能把它还给图书馆。

(2)表示动作或状态从过去某时开始一直延续到现在,并可能延续下去。

常与so far,by now,up to now,since,for a long time,up till now,in the past/last few years 等表示一段时间的状语连用。

He has worked here for twenty years by now.到现在为止,他已经在这儿工作20年了。

Up to now,we have received no letters from her.到现在为止,我们没有收到她一封信。

[名师点津](1)该用法中的动词多是延续性动词,不能是非延续性动词或趋向动词。

(2)非延续性动词用于否定句可以表示否定的状态,故可以用来表示状态的持续。

(3)由since引导的时间状语中,since后面的时间名词必须是“时间点”,而不能是“时间段”;而for短语中的时间名词必须是“时间段”(有时for可省去)。

I've known him since 1980.我从1980年就认识他了。

I have learnt English (for) many years.我学英语已很多年了。

[即时演练1]用所给动词的适当形式填空①The price has gone (go)down,but I'm not sure whether it will remain so.②All the windows have been painted (paint),and they look new.③I have read (read)many reports about the UFO recently.④In the last few years,China has made (make) great achievements in environmental protection.⑤His first novel has received (receive) good reviews since it came out last month.2.现在完成时的常用句型(1)It/This is the first/second/...time that+主语+谓语部分(常用现在完成时)(2)It has been+一段时间+since...(3)It/This/That is the+最高级+名词+定语从句(定语从句常用现在完成时)It is the first time that I've heard of the story about Crop Circles.这是我第一次听说麦田怪圈的故事。

现在完成时一、知识梳理要点一:现在完成时用来表示之前已发生或完成的动作或状态,但它的影响现在还存在;也可表示持续到现在的动作或状态。

要点二:1、构成:have (has) +过去分词。

规则变化的过去分词与过去式的变化一样,在动词词尾加ed; 不规则变化的过去分词见不规则动词表,需要同学记忆。

现以see the film为例将现在完成时的肯定句,否定句和疑问句列表如下:肯定句:I/You/We/They have seen the film. He/She /It has seen the film.否定句:I/You/We/They have not/ haven’t seen the film.He/ She/It has not/hasn’t seen the film.疑问句:Have I/you/they seen the film? Yes, you/ we/I/they have. No, you/ we/I/they haven’t.Has he/she/it seen the film? Yes, he/ she/ it has. No, he/ she/ it hasn’t.2、变化规则:与动词过去式规则相同。

①一般直接在词尾加上ed。

look —looked②以e结尾的动词,直接加d。

move —moved③以y结尾,y前面是辅音字母的动词,变y 为i,再加ed。

carry —carried④部分动词需双写尾字母,加ed。

stop —stopped⑤不规则变化AAB型ABB型用法:现在完成时既涉及过去,又联系现在。

用法1:表示过去发生或已经完成的某一动作对现在造成的影响或结果。

常与just(刚刚),already(已经),never(从来没有),ever(曾经),before(以前),yet(仍然),once(一次),twice(两次),many times(很多次),how many times(多少次),so far(迄今为止),during the past(last)three years(最近三年来)等连用。

※副词的位置:①just常用于肯定句中,放在have / has后,He has just come .②never表示否定, 放在have / has后, He has never visited the Great Wall.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。

Have you ever been to the farm?④before用于句末,The woman has never heard of that before.⑤yet 用于句末或not 之后. Has the train arrived yet? No, not yet.⑥already用于肯定句, have / has 之后或句末.We have already finished it.⑦so far用于句首或句末. So far, we have visited the moon.用法2: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I have taught English for 19 years。

②since+表示过去时间点的词语He has been at this school since 1986.③since+表示过去的时间状语从句I have lived here since I was born.④since+一段时间+ago. I have known him since 20 years ago.用法3:表示到现在为止多次发生的动作,常带有twice, ever, never, three times等时间状语。

I have been to Beijing twice. 我去过北京两次。

He has watched the film twice. 这部电影他已经看过两遍了。

要点四:现在完成时态中,可以和表示一段时间状语(for,since,how long, all one’s life)连用的动词必须是表示延续的情况或动作的动词,即延续性动词。

如:be,have,know,live,work,study,learn,teach,keep,speak,talk,draw,wait,wear,walk,sleep,drive,write,do,clean等。

I have been a teacher for nearly 20 years. How long has he lived here?要点五:延续性动词的现在完成时可和包括“现在”在内的(到说话时仍未结束)表示一段时间的状语连用。

如this morning,today,this week,these daysHe has been to Beijing three times this year.He has written two letters this morning.(说话时间在上午)He wrote two letters this morning.(说话时间在下午或晚上)要点六:英语中还有一些动词的意义决定它们所表示的动作不能延续,只是一瞬间就结束的动作,这类动词叫做“非延续性动词”(短暂性动词/瞬间动词),常见的有:come,go,arrive,reach,see,hear,close,open,leave,begin,start,lose,buy,fall,join,die,get up,become,borrow,lend,find,finish,receive等。

这些动词可用于现在完成时,说明某个动作的结果还存在,但不能和表示一段时间的状语(how long,for,since)连用。

He has come back.(√)He has come back for two hours.(×)※但在否定句中,非延续性动词也可用表示一段时间的状语来修饰(因为非持续性动词的这种否定形式构成一种状态,而这一状态是可以持续的),如I haven’t heard from my father for a long time.We haven’t seen him since 1999.【注意】:当终止性动词(非延续性动词)与表示一段时间的状语(how long,since,for,all one’s life)相矛盾时,改正错句的方法有如下几种:(1)用副词ago把现在完成时的句子改为一般过去时.He has come back for two weeks.(错)改为:He came back two weeks ago.(正)I have lost my bike for ten days. (错)改为:I lost my bike ten days ago. (正)(2)用“It is / has been+时间+since+一般过去时态”句型来改写。

He has joined the League(社团)for 3 years. (错)It is 3 years since he joined the League.I have bought the book for 5 days. (错)It is 5 days since I bought the book. (正)He has died for 20 years. (错)It is 20 years since he died. (正)(3)用“时间+has passed+since+一般过去时态”句型来改写。

He has left home for 20 years. 改为:Twenty years has passed since he left home.He has lost his pen for 2 days. 改为:Two days has passed since he lost his pen. (4)用系表结构来改写.He has died for 20 years. 改为: He has been dead for 20 years.The factory has opened since 1999. 改为:The factory has been open since 1999.How long has he left? 改为:How long has he been away?(5)用相应的延续性动词替代非延续性动词。

He has bought the book for two weeks. 改为:He has had the book for two weeks. 常见的相应转换形式如下:borrow / lend→keep,buy/catch→have,finish / stop/end→be over, begin / start→be on , open→be open ,close→be closed,die→be dead ,leave→be away(from), get up→be up,fall asleep→be asleep , fall ill→be ill,Married→be married get to know→know,lose→be lost,become→be,begin to study→study,join→be in / be a member of,receive / get a letter→have a letter ,catch / get a cold→have a cold,join the army→be in the army /be a soldier, return / come back / get back→be back,go to school→be in school / be a student, arrive /come / go / move / reach /get to→be in /at / be here /be there,他参军已有三年.He has joined the army for three years.(错)改为:He has been in the army for three years / since three years ago.He has been a soldier for three years / since three years ago.He joined the army three years ago.It is three years since he joined the army.Three years has passed since he joined the army.要点七:现在完成时中应注意的几个问题have/has gone to;have/has been to;have/has been in的区别have/has gone to:已经去了,还没有返回;强调“去了”,现在人不在说话的现场have/has been to:曾经去过某地,现在已经回来了,后面可接表示“次数”的状语;have/has been in: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。
