2、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 to
3、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+not14特殊疑问句:特殊疑问词+have/ha
4、s+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、 afternoon) ,last(m orning、 after noon)等,除非与for, si nee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, reeently, still, lately,Just, already, yet, ever, never, before, twiee(重复性时间),for+ 短时间,si
5、nee+ 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 reee ntly (lately).We have see n that film before.Have they found the missing ehild yet ?2. 现在完成时常常与表示频度的时间状语连用,如 ever, never, twiee, several times 等:Have you ever bee n to Beiji ngI have n ever

7、nt everything 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.
8、 瞬间性动词 : 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, enter, hear, stop, open, close, become, buy, borrow, lend, happen, join, lose, renew, 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
9、来替换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 up Has your brother been 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、go be away 2、come be here 3、come back be back4、leave beaway (be
10、 not here) 5、buy have6、borrowkeep 7、die bedead8、begin be on 9、finish be over10、open be open11、closebe closed12、losebe lost13、get to knowknow14、turn on be on 15、get upbe up 16、sit down sit/beseated17、join be in ()或 be a member18、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 lon
11、g tim(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;现
12、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 / un
13、til, up to now, in past years, always,六现在完成时的反义疑问句的结构 l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't she D. isshe析:陈述句部分含否定词n
14、ever,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 uncleposted 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 Sha nghai. -Soher pare nts. A. has B. had C. did D.have析:"so+助/系/情态动词+主语"结构中的动词形
15、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? -youyour homeworkyet?A. Do; finish B. Are; fini shi ngC. Did; finish D. Have; fini shed2. -youany where before? -Yes, but I can't remember
16、whereIA. Did; surf; surfed B. 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 bee n to Stone Forest twicehe came
17、 to Yunnan.A. after B. before C. since 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't got C. didn't
18、 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, I have.A. went to B. gone to C. been in D. be
19、en 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、考查现在完成时与其他时态的联系和区别。如:1. S
20、un'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 Sun's aunt went th
21、ere.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si nee引导的从句要用一般过去时,故填It is, since, came。3. 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,而且对现在造成了我不能参加音乐会的结 果,符合现在
