2、s morning month year.，today等)连用。例如： Have you found your pen yet？你已找到你的钢笔了吗？2.现在完成时的未完成用法 现在完成时的未完成用法指的是动作开始于过去某一时刻，一直延续到现在，或可能还要继续下去。例如：He has lived here since 1978.自从1978年以来，他一直住在这儿。(动作起始于1978年，一直住到现在，可能还要继续住下去。) I have been in the army for more than 5 years.我在部队已经呆了五年多了。(动作开始于5年前，一直延续至今，有可能还要继续下去。

3、) 此种用法的句中常需一个表示一段时间的状语(由since或for引导)，或表示与现在时刻相连的时间状语(如：up to now，so far到目前为止)等。例如：I have heard nothing from him up to now.到目前为止我没有他的任何消息。 注意：(1)现在完成时的未完成用法只适用于延续性动词，不可用于终止性动词，即瞬间完成或延续时间很短的动词。如：come，go，arrive，leave，join，become，die等。 (2)现在完成时常见两种句型：主语have / has beenfor短语 It is一段时间 since从句 例如：He has be

4、en in the League for three years.或It is three years since he joined the League. 他入团已三年了。3、延续性动词和终止性动词的概念英语中，动词按其动作发生的方式、动作发生过程的长短，可分为延续性动词和终止性动词。延续性动词 表示能够延续的动作，这种动作可以延续下去或产生持久影响。如：learn, work, stand, lie, know, walk, keep, have, wait, watch, sing, read, sleep, live, stay等。终止性动词 也称非延续性动词、瞬间动词或短暂性动词，

5、表示不能延续的动作，这种动作发生后立即结束。如open, close, finish, begin, come, go, arrive, reach, get to, leave, move, borrow,buy等。4、延续性动词的用法特征1.延续性动词可以用于现在完成时，其完成时态可与表示段时间的状语连用。表示段时间的短语有：for two years, during the past three years, since last year, how long等。如：I have learned English since I came here.自从我来到这儿就学英语了。2.延续性动词

6、不能与表示短暂时间的点时间状语连用。如：It raind at eight yesterday morning.(误) rain为延续性动词，而at eight表示点时间，前后显然矛盾。如果用延续性动词表示一瞬间的动作，可以借助come, begin, get等终止性动词来表示。上句可改为：It began to rain at eight yesterday morning.(正)又如：-When did you get to know Jack?-Two years ago.-Then youve known each other for more than two years.-That

7、s right.5、终止性动词的用法特征1.终止性动词可用来表示某一动作完成，因此可用于现在完成时。如：The train has arrived.火车到了。Have you joined the computer group? 你加入电脑小组了吗？2.终止性动词表示的动作极其短暂，不能持续。因此，不可与表示一段时间的状语连用(只限肯定式)。如：(1)他死了三年了。 误：He has died for three years.正：He has been dead for three years. 正：He died three years ago.正：It is three years sin

8、ce he died. 正：Three years has passed since he died.(2)他来这儿五天了。 误：He has come here for five days.正：He has been here for five days. 正：He came here five days ago.正：It is five days since he came here. 正：Five days has passed since he came here. (1)、(2)句中的die、come为终止性动词，不能与表示段时间的状语连用。那么，应如何正确表达呢？可以采用下面的四种

9、方法： (1)将句中终止性动词转换为相应的延续性动词，如上面两例中的第一种正确表达方式。下面列举几例：leavebe away, borrowkeep, buyhave, begin/startbe on, diebe dead, move tolive in, finishbe over, joinbe in/be a member of, open sth.keep sth. open, fall illbe ill, get upbe up, catch a coldhave a cold。 (2)将句中表示段时间的状语改为表示过去确定时间的状语，如下面两例中的第二种正确表达方式。 (3

10、)用句型It is+段时间+since.表达原意，如上面两例中的第三种正确表达方式。 (4)用句型时间+has passed+since.表达原意，如上面两例中的第四种正确表达方式。3.终止性动词可用于现在完成时否定式中，成为可以延续的状态，因而可与表示一段时间的状语连用。如：He hasnt left here since 1986.I havent heard from my father for two weeks.4.终止性动词的否定式与until/till连用，构成not+终止性动词+until/till .的句型，意为直到才。如：You cant leave here until

11、I arrive.直到我到了，你才能离开这里。I will not go to bed until I finish drawing the picture tonight.今天晚上直到我画完画，我才上床睡觉。5.终止性动词可以用于when引导的时间状语从句中，但不可以用于while引导的时间状语从句中。when表示的时间是点时间(从句谓语动词用终止性动词)，也可以是段时间(从句谓语动词用延续性动词)。而while表示的是一个较长的时间或过程，从句谓语动词用延续性动词。如：When we reached London, it was twelve oclock. (reach为终止性动词)Pl

12、ease look after my daughter while/when we are away. (be away为延续性动词短语)6.终止性动词完成时不可与how long连用(只限于肯定式)。如：误：How long have you come here? 正：How long have you been here?正：When did you come here?二、现在完成时与一般过去时的区别1. 一般过去时表示过去某个时间发生的事、存在的状态或经常发生的动作。说话的侧重点只在于陈述一件过去的事情，不强调对现在产生的影响。如：He visited Guilin in 1998.他

13、1998年参观过桂林。(只说明去桂林的时间)2. 现在完成时表示动作发生在过去，对现在造成了影响或产生了结果。不与确定的过去时间状语连用。如：Jill has bought a new computer.吉尔买了一台新电脑。(着重点是现在有了一台新电脑)3. 两种时态的区分 (1)一般过去时的谓语动词用过去式，而现在完成时的谓语基本构成是助动词have /has +过去分词。如：The film started at 7 oclock. He has been a teacher for many years. (2)一般过去时通常与表示过去的时间状语连用。如：yesterday, last

14、week, two years ago, just now, in 2002等；而现在完成时则常与just, already, ever, never等副词和these days, this week, since., for.等表示一段时间的状语连用。看看以下的几组句子，有什么区别？ Have you seen the film?(A) Did you see the film?(B) 说明 你看过这部电影吗？(A)句强调的是被问者对剧情是否了解；(B)句强调的是看这部电影的动作是否发生过，并不强调是否知道其内容。 How has he done it?(A) How did he do i

15、t?(B)说明他是怎么做的这件事？(A)句强调的是他做这件事的方式对现在产生了某种影响；(B)句单纯的询问做这件事的方式。 He has lived in Beijing for 8 years.(A) He lived in Beijing for 8 years.(B)说明他在北京住了8年。(A)句讲的是到目前为止他在北京住了8年，可能还会继续在北京住下去。(B)句讲的是他在北京住过8年，现在不在北京了。三、现在完成时考点例析现在完成时是较难掌握、中考考查较多的时态。涉及的考点有：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. Kates never se

16、en Chinese films，_ ? A. hasnt she B. has she C. isnt she D. is she析：陈述句部分含否定词never,简略问句部分要用肯定式，又因Kates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hasnt, yet。3. -Ann has gone to Shanghai. -So _her

17、 parents. 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? -_you_ your homework yet? A. Do; finish B. Are; finishing C. Did; finish D. Have; f

18、inished2. -_ you _anywhere before? -Yes, but I cant remember where I_A. Did; surf; surfed B. Have; surfed; surfed C. 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since +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

19、has been to Stone Forest twice_he came 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. Tom_the 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. I_a letter from him since he left. A. didnt receive B. haven

20、t got C. didnt have D. havent 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 ever_Lintong to see the Terra Cotta Warriors?-Yes, I have. A. went to B. gone to C. been in D. been to析：据句中的have，排除A，B项意为

21、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for+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. Suns 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

22、过去时或借助句型Its +段时间+since+从句进行句子转换。故答案为：Suns aunt has been there for ten years. /Suns aunt went there ten years ago. /Its ten years since Suns 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, si

23、nce, came。3. I wont go to the concert because I _my ticket. A. lost B. dont 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，符合现在完成时所表示的含意，故选C。现在完成时专项练习题及答案一、单项选择。1、Both his parents look sad .

33、从上下文分析、推理才行。故上两侧根据上下文分析、推理，正确答案是。 2、现在完成时常与already（已经），just（刚刚，正好），ever（曾经），never（从来，也不；从不），before（以前），yet（仍然）等连用。故2应选B。 3、C 4、现在完成时常与recently（近来），so far（到目前为止），in the past/“last + 一段时间”等时间状语连用。因为上述短语表示的是从现在起往前推算的一段时间，句中的动作是从过去某一时间或时刻开始持续到现在的。故4应选D。 5、C 6、现在完成时时常与“for +时间段或since +过去时间点”连用（含从句，从句过去时）

34、。故6应选C。 7、C 8、现在完成时还与once（一次），twice（两次），three times（三次），several times（几次）等表示重复次数的词语连用。故8应选B。 9、现在完成时与一般过去时容易混淆，就是因为它们所表示的动作都发生在过去，但二者又有区别：一般过去时表示过去某个时间发生的事、存在的状态或经常发生的动作，说话的侧重点在于陈述一件过去的事情，与现在没有关系；现在完成时表示与现在有关系的发生在过去的动作，它不与表示过去的时间状语（如yesterday , last week , a moment ago等）连用。故9的正确答案为B。 10、B 11、现在完成时中，

35、非延续性动词不能与for和since引导的表示一段时间的状语连用，通常是用相应的延续性动词来代替。故11的正确答案依次为：D。 12、B 13、A 14、C 15、A。 16、“have/has gone to + 地点”表示“某人去了某地（还未回来）”，指主语所指的人不在这儿。“have/has been in + 地点”表示“在某地呆了多长时间”，常与表示时间的状语连用。“have/has been to +地点”表示“曾经去过某地（但现在已不在那儿）。”故16的正确答案为A。 17、A 18、D 19、C 20、C 二、句型转换。 1、has he? 2、How long 3、died,

36、 has been dead 4、has been open 5、has been away 6、joined；ago 7、It is, since 8、The bus has been here for ten minutes. 三、汉译英。 1、Jim has finished doing his homework already. He is free now. 2、He received a letter yesterday. 3、My father has been to the Great Wall before. 4、She hasnt seen the new film yet

37、. 5、She has been to Shanghai. 6、Where has he been these days？(UNIT2)过去进行时（注意when while as引导的时间状语从句。）(UNIT3)被动语态复习“三步曲”被动语态是动词语态的一种形式,表示主语是动作的承受者。在历年的中考题中,都有一定数量的考查被动语态的题目。因此,有必要对被动语态进行系统复习。第一曲:掌握被动语态的结构被动语态由助动词+及物动词的过去分词构成。不同时态的被动语态的差异主要体现在助动词be的变化上,同时助动词be还要在人称和数上与主语保持一致。现将初中阶段常见的几种时态的被动语态总结如下:1.一般

38、现在时的被动语态:am/is/are+done(指及物动词的过去分词,下同)如:English is used all over the world.2.一般过去时的被动语态:was/were+done如: The picture was painted two years ago.3.现在进行时的被动语态:am/is/are+being+done如: The flowers are being watered by them now. 4.现在完成时的被动语态:have(has)+been+done如:The room has been cleaned.5.一般将来时的被动语态:will/b

39、e going to+be+done如:The work will be finished tomorrow.6.含有情态动词的被动语态:情态动词+be+done如:Your homework must be handed in today.其它几种特殊句型：It is said that . It is well known that . It is reported that.have sth done 第二曲:掌握主动语态变被动语态的方法把主动语态变为被动语态时,应走好以下三步:1)主动语态的宾语变为被动语态的主语; 2)主动语态的谓语动词由主动语态形式变为被动语态形式; 3)主动结构的

40、主语变为介词by的宾语,组成介词短语,放在被动结构的谓语动词之后。在无须说明动作的执行者或只强调动作的承受者时,by短语可以省略。请看示范:主动语态:My brother repaired that bike yesterday. 主语 谓语动词 宾语其余部分被动语态:That bike was repaired (by my brother) yesterday. 主语 谓语动词 by+宾语其余部分对于主动语态变为被动语态方法的考查,主要在句型转换题目中出现。只要能够按照上面介绍的方法去做,一般是能够做对的。第三曲:注意主动语态变为被动语态的几种特殊句型1.含有短语动词的被动语态一般来说,只

41、有及物动词才有被动语态。另外,许多不及物动词加上介词或副词构成的短语动词,相当于及物动词,后面也可加宾语。在变被动语态时,注意不可丢掉后面的介词或副词,常见的这类短语动词有:take care of, look after, take off, look at, send for, look up等。如:The old people should be taken good care of.2.含有双宾语的动词的被动语态含有双宾语的主动句改为被动句时,应将其中一个宾语改为被动结构的主语,另一个宾语仍保留在原处。一种情况是把间接宾语(指人)变为主语,直接宾语(指物)不变。另一种情况是把直接宾语(

42、指物)变为主语,间接宾语(指人)不变,这时,间接宾语前通常加介词to,有时加for。如:My father gave me a new book on my birthday.I was given a new book (by my father) on my birthday. (间接宾语作了主语)A new book was given to me (by my father) on my birthday. (直接宾语作了主语)3.带有复合宾语的动词的被动语态带有复合宾语(宾语和宾语补足语)的主动语态变为被动语态时,只把宾语变为被动语态的主语,原来的宾语补足语不动。同时,如果宾语补足语是省略to的动词不定式,变为被动语态时,必须加上不定式符号to,这类动词有make, let, see, hear, watch等。如:W
