2、her these da这些日子我没有收到她的信。We haven ' t seen you recentiy最近我们没有见至M尔。They have bee n away for two years.他们离开已经两年了。She has bee n with us since Mon day.3).现在完成时还可以用来表示过去的一个时间到现在这段时间内重复发生的动作.We have had four texts this semester.6. have been to 和 have gone to的区另Uhave been to强调 去过”,现已不在那里,如:He has bee n
3、 to the USA three times.他到美国去过三次。(过去到美国”,现在已不在美国”)have gone to主要强调的是 去了”,现在人不在说话的现场,如:-Where's your mother?-你妈妈在哪?-She has gone to the hospital.她去医院了。一结构厂1肯定句:主语+have/has+动词的过去分词+其他2否定句:主语+have/has+not动词的过去分词+其他-3般疑问句:have/has主语+动词的过去分词+其他Yes,主语 +have/has No ,主语+have/has+not3 4特殊疑问句:特殊疑问词+have/h
4、as+主语+动词的过去分词+其他二 常和现在完成时一起连用的时间状语注意:.现在完成时不能单独与准确时间连用,(如表示过去的时间状语)如 yesterday(m orning 、after noon) ,last(m orning 、after noon)等, 除非与for, since连用.1. 现在完成时往往同表示不确定的过去时间状语连用如 already (肯定),yet (否定,疑问),just, before, recently, still, lately ,Just, already, yet, ever, never, before, twice(重复性时间),for+ 短时间
5、,since+点时间,so far, how long提问的疑问句中 He has already obta ined a scholarship.I have n't see n much of him rece ntly (lately).We have see n that film before.Have they found the missing child yet ?2. 现在完成时常常与表示频度的时间状语连用如 ever, never, twice, several times 等 :Have you ever been to BeijingI have never h
6、eard Bunny say anything against her.I have used this pen only three times. It is still good.George has met that gentleman several times.3. 现在完成时还往往可以同包括现在时间在内的时间状语连用 如 up to these few days/weeks/months/years, just, up to present(now), so far 等 :Peter has written six papers so far.Up to the present e
7、verything has been successful.三 当现在完成时与表示短时间的时间状语连用时,谓语动词必 须使用延续性动词。如果谓语动词是非延续性动词则转化为对应的延 续性动词。 若不是和短时间连用,则不用转化。英语的行为动词有持续性动词和瞬间性动词之分,使用中应注意两者的区 别。1. 持续性动词 : 表示一个动作可以持续一段时间或更长时间。常见的 study, play, do, read, learn, drive, write, clean , sleep, speak, talk, wait, fly, stay, sit, stand, lie, keep 等。2. 瞬间
8、性动词 : 表示一个动作发生在一瞬间,非常短暂。亦称终止性动词。 常见的 -begin, start, finish, go, come, leave, find, get up, arrive, reach, get to,en ter, hear, stop, ope n, close, become, buy, borrow, le nd, happe n, jo in, I ose,ren ew, die, take away, put up, set out, put on, get on/off 等3瞬间性动词在完成时中如要与表示持续一段时间的状语连用,通常用意思相当的持续性动词来
9、替换He has been in the army/a soldier for three years. (他参军已有 3 年了。)不 用 has joinedShe has been up for quite some time.(她起床已有好久了。 )不用 has got upHas your brother bee n away from home for a long time?(离家已有好久了吗?)不用has left常用瞬间动词相应持续性动词关系:1、gobe away2、come be here 3、come back be back4、6> borrow keep7、le
10、ave be away( be not here) 5、buyhavediebe dead8、beg inbe on 9、finish be over10、ope nbe open11、closebe closed12、losebe lost 13、get to know know14、turn on be on15、get upbe up 16、sit down sit/beseated 17、join be in ()或 be a member 18、become be4. 瞬间动词的否定形式可以与表示一段时间的状语连用例如:I haven ' t seen you for a l
11、ong time.(好久没见到你了。)四区别下面三组词Have been to表示去过某地方,不过现在已经回来 Have gone to 表示去了,还未回来Have been in 表示一直在某个地方五现在完成时和一般过去时的区别现在完成时用来表示之前已发生或完成的动作或状态,其结果的确和现在有联系。 动作或状态发生在过去,但它的影响现在还存在;而一般过去时表示过去的事实, 不表示和现在的关系。I have just bee n to London. I went there last mon th.我刚去过伦敦,是上个月去的。1. 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;
12、现在完 成时为过去发生的,强调过去的事情对现在的影响,强调的是影响。2. 过去时常与具体的时间状语连用,而现在完成时通常与模糊的时间状语连 用,或无时间状语。一般过去时的时间状语:yesterday, last week ago, in1980, in October, just now,具体的时间状语共同的时间状语:this morning, tonight, this April, now, once, before, already, recently, lately现在完成时的时间状语for, since, so far, ever, never, just, yet, till /
13、until, up to now, in past years, always,六现在完成时的反义疑问句的结构主语+have/has+动词过去分词+其他,have/has+not+主语 主语+have/has+not+动词过去分词+其他,have/has+主语七现在完成时考点例析一、考查其构成"助动词have (has) +动词过去分词"构成现在完成时。如:1. Kate's n ever see n Chin ese films ,? A. has n't she B. has she C. is n'tshe D. is she析:陈述句部分含否
14、定词never,简略问句部分要用肯定式,又因 Kate's是Kate has的缩写,故选B。2. His uncle has already posted the photos to him. ( 改为否定句 )His uncle posted the photos to him .析:already常用在肯定句中,yet常用在否定句、疑问句中,故填 has n't, yet。3. -Ann has gone to Shanghai. -So her parents. A. has B. had C. did D.have析:"so+助/系/情态动词+主语"
15、结构中的动词形式应与前句结构中动词形式保持 一致,又后句的主语为 her parents 是复数 ,故选 D。二、考查其用法与标志词(一)当句中有 never, ever, just, already, yet, before 等时,常用现在完成时。如:1. -Mum, may I go out and play basketball? -youyourhomework yet?A. Do; finish B. Are; finishing C. Did; finish D. Have; finished2. - you anywhere before? -Yes, but I can'
16、;t remember whereIA. Did; surf; surfedB. Have; surfed; surfedC. Did; surf; have surfed D. Have; surfed; have surfed析:据 yet 和 before 可知,应用现在完成时,故 1 题选 D, 2 题选 D。(二)当句中有"for +段时间"或"sinee +点时间"等时,主句常用现在完成时,谓语 动词必须是延续性动词 ,若是非延续性动词 ,要改为延续性动词或表状态的词 (短 语 )。如:1. His brother has been to S
17、tone Forest twieehe eame to Yunnan.A. after B. before C. sinee D. for析:主句用的是现在完成时,而从句用的是一般过去时,故选C。2. Tomthe CD player for two weeks.A. has lent B. has borrowed C. has bought D. has had析:A、B、C均为非延续性动词,在肯定句中不与表"段时间"的短语连用,故选D。3. Ia letter from him since he left.A. didn't receive B. haven&
18、#39;t got C. didn't have D. haven't heard析:据 since 可知,应排除 A、 C, "hear from sb.=receive/get/have a letter from sb."意为"收到某人的来信",故选B。三、考查 have/has been (to, in)/have/has gone (to) 的区别 。如:1. -Have you everLintong to see the Terra Cotta Warriors? -Yes, Ihave.A. went to B. gone
19、 to C. been in D. been to析:据句中的have,排除A,B项意为"去某地了 ",C项意为"一直呆在某地", D 项意为 "去过某地 ",符合题意,故选 D。2. My parents Shangdong for ten years.A. have been in B. have been to C. have gone to D. have been析:本题句中有"fo叶段时间"结构,据此可排除C,B项意为"去过某地",不合题 意, D 项缺介词,故选 A。四、考查现在完
20、成时与其他时态的联系和区别。如:1. Sun's aunt has gone there for ten years.( 改成正确的句子 )析:非延续性动词与 "段时间 "连用时,除了把非延续性动词改成延续性动词外, 还可把动词改为一般过去时或借助句型"It's +段时间+since+从句"进行句子转 换。故答案为: Sun's aunt has been there for ten years. /Sun's aunt went there ten years ago. /It's ten years since
21、 Sun's aunt went there.2. Susan has been in this city for more than ten years.( 改为同义句 )more than ten years Susan to this city.析:据上题分析,且 since 引导的从句要用一般过去时,故填 It is, since, came3. I won't go to the concert because I my ticket.A. lost B. don't lose C. have lost D. is coming 析:因我丢了票的动作发生在过去
22、,而且对现在造成了我不能参加音乐会的结 果,符合现在完成时所表示的含意,故选C。现在完成时的练习(一)一、 单项选择1、 Both his parents look sad. Maybe they what's happened to him .A. knew B . have known C . must know D. will know2、 He has been to Shanghai, has he?A . alreadyB . neverC . everD . still3、Have you met Mr. Li ?A . justB . agoC .beforeD .a
