牛津八下英語語法總復(fù)習(xí)一、現(xiàn)在完成時的“完成用法”和“未完成用法”1.現(xiàn)在完成時的完成用法 現(xiàn)在完成時的完成用法指的是動作發(fā)生在過去某一時刻并已結(jié)束，但該動作對現(xiàn)在產(chǎn)生了影響，與現(xiàn)在情況具有因果關(guān)系。例如：He has turned off the light.他已把燈關(guān)了。(動作結(jié)束于過去，但說明的是現(xiàn)在的情況-燈現(xiàn)在不亮了。)現(xiàn)在完成時完成用法的特點是動作不延續(xù)，因此，該時態(tài)只能與表示不定的過去時間狀語(如：already，yet，before，recently等)、頻度時間狀語(如：never，ever，once等)、包括現(xiàn)在時刻在內(nèi)的時間狀語(如：this morning month year.，today等)連用。例如： Have you found your pen yet？你已找到你的鋼筆了嗎？2.現(xiàn)在完成時的未完成用法 現(xiàn)在完成時的未完成用法指的是動作開始于過去某一時刻，一直延續(xù)到現(xiàn)在，或可能還要繼續(xù)下去。例如：He has lived here since 1978.自從1978年以來，他一直住在這兒。(動作起始于1978年，一直住到現(xiàn)在，可能還要繼續(xù)住下去。) I have been in the army for more than 5 years.我在部隊已經(jīng)呆了五年多了。(動作開始于5年前，一直延續(xù)至今，有可能還要繼續(xù)下去。) 此種用法的句中常需一個表示一段時間的狀語(由since或for引導(dǎo))，或表示與現(xiàn)在時刻相連的時間狀語(如：up to now，so far到目前為止)等。例如：I have heard nothing from him up to now.到目前為止我沒有他的任何消息。 注意：(1)現(xiàn)在完成時的未完成用法只適用于延續(xù)性動詞，不可用于終止性動詞，即瞬間完成或延續(xù)時間很短的動詞。如：come，go，arrive，leave，join，become，die等。 (2)現(xiàn)在完成時常見兩種句型：主語have / has beenfor短語 It is一段時間 since從句 例如：He has been in the League for three years.或It is three years since he joined the League. 他入團(tuán)已三年了。3、延續(xù)性動詞和終止性動詞的概念英語中，動詞按其動作發(fā)生的方式、動作發(fā)生過程的長短，可分為延續(xù)性動詞和終止性動詞。延續(xù)性動詞 表示能夠延續(xù)的動作，這種動作可以延續(xù)下去或產(chǎn)生持久影響。如：learn, work, stand, lie, know, walk, keep, have, wait, watch, sing, read, sleep, live, stay等。終止性動詞 也稱非延續(xù)性動詞、瞬間動詞或短暫性動詞，表示不能延續(xù)的動作，這種動作發(fā)生后立即結(jié)束。如open, close, finish, begin, come, go, arrive, reach, get to, leave, move, borrow,buy等。4、延續(xù)性動詞的用法特征1.延續(xù)性動詞可以用于現(xiàn)在完成時，其完成時態(tài)可與表示段時間的狀語連用。表示段時間的短語有：for two years, during the past three years, since last year, how long等。如：I have learned English since I came here.自從我來到這兒就學(xué)英語了。2.延續(xù)性動詞不能與表示短暫時間的點時間狀語連用。如：It raind at eight yesterday morning.(誤) rain為延續(xù)性動詞，而at eight表示點時間，前后顯然矛盾。如果用延續(xù)性動詞表示一瞬間的動作，可以借助come, begin, get等終止性動詞來表示。上句可改為：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.-Thats right.5、終止性動詞的用法特征1.終止性動詞可用來表示某一動作完成，因此可用于現(xiàn)在完成時。如：The train has arrived.火車到了。Have you joined the computer group? 你加入電腦小組了嗎？2.終止性動詞表示的動作極其短暫，不能持續(xù)。因此，不可與表示一段時間的狀語連用(只限肯定式)。如：(1)他死了三年了。 誤：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 since he died. 正：Three years has passed since he died.(2)他來這兒五天了。 誤：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為終止性動詞，不能與表示段時間的狀語連用。那么，應(yīng)如何正確表達(dá)呢？可以采用下面的四種方法： (1)將句中終止性動詞轉(zhuǎn)換為相應(yīng)的延續(xù)性動詞，如上面兩例中的第一種正確表達(dá)方式。下面列舉幾例：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)將句中表示段時間的狀語改為表示過去確定時間的狀語，如下面兩例中的第二種正確表達(dá)方式。 (3)用句型It is+段時間+since.表達(dá)原意，如上面兩例中的第三種正確表達(dá)方式。 (4)用句型時間+has passed+since.表達(dá)原意，如上面兩例中的第四種正確表達(dá)方式。3.終止性動詞可用于現(xiàn)在完成時否定式中，成為可以延續(xù)的狀態(tài)，因而可與表示一段時間的狀語連用。如：He hasnt left here since 1986.I havent heard from my father for two weeks.4.終止性動詞的否定式與until/till連用，構(gòu)成not+終止性動詞+until/till .的句型，意為直到才。如：You cant leave here until I arrive.直到我到了，你才能離開這里。I will not go to bed until I finish drawing the picture tonight.今天晚上直到我畫完畫，我才上床睡覺。5.終止性動詞可以用于when引導(dǎo)的時間狀語從句中，但不可以用于while引導(dǎo)的時間狀語從句中。when表示的時間是點時間(從句謂語動詞用終止性動詞)，也可以是段時間(從句謂語動詞用延續(xù)性動詞)。而while表示的是一個較長的時間或過程，從句謂語動詞用延續(xù)性動詞。如：When we reached London, it was twelve oclock. (reach為終止性動詞)Please look after my daughter while/when we are away. (be away為延續(xù)性動詞短語)6.終止性動詞完成時不可與how long連用(只限于肯定式)。如：誤：How long have you come here? 正：How long have you been here?正：When did you come here?二、現(xiàn)在完成時與一般過去時的區(qū)別1. 一般過去時表示過去某個時間發(fā)生的事、存在的狀態(tài)或經(jīng)常發(fā)生的動作。說話的側(cè)重點只在于陳述一件過去的事情，不強(qiáng)調(diào)對現(xiàn)在產(chǎn)生的影響。如：He visited Guilin in 1998.他1998年參觀過桂林。(只說明去桂林的時間)2. 現(xiàn)在完成時表示動作發(fā)生在過去，對現(xiàn)在造成了影響或產(chǎn)生了結(jié)果。不與確定的過去時間狀語連用。如：Jill has bought a new computer.吉爾買了一臺新電腦。(著重點是現(xiàn)在有了一臺新電腦)3. 兩種時態(tài)的區(qū)分 (1)一般過去時的謂語動詞用過去式，而現(xiàn)在完成時的謂語基本構(gòu)成是助動詞have /has +過去分詞。如：The film started at 7 oclock. He has been a teacher for many years. (2)一般過去時通常與表示過去的時間狀語連用。如：yesterday, last week, two years ago, just now, in 2002等；而現(xiàn)在完成時則常與just, already, ever, never等副詞和these days, this week, since., for.等表示一段時間的狀語連用?？纯匆韵碌膸捉M句子，有什么區(qū)別？ Have you seen the film?(A) Did you see the film?(B) 說明 你看過這部電影嗎？(A)句強(qiáng)調(diào)的是被問者對劇情是否了解；(B)句強(qiáng)調(diào)的是看這部電影的動作是否發(fā)生過，并不強(qiáng)調(diào)是否知道其內(nèi)容。 How has he done it?(A) How did he do it?(B)說明他是怎么做的這件事？(A)句強(qiáng)調(diào)的是他做這件事的方式對現(xiàn)在產(chǎn)生了某種影響；(B)句單純的詢問做這件事的方式。 He has lived in Beijing for 8 years.(A) He lived in Beijing for 8 years.(B)說明他在北京住了8年。(A)句講的是到目前為止他在北京住了8年，可能還會繼續(xù)在北京住下去。(B)句講的是他在北京住過8年，現(xiàn)在不在北京了。三、現(xiàn)在完成時考點例析現(xiàn)在完成時是較難掌握、中考考查較多的時態(tài)。涉及的考點有：一、考查其構(gòu)成助動詞have (has) +動詞過去分詞構(gòu)成現(xiàn)在完成時。如：1. Kates never seen Chinese films，_ ? A. hasnt she B. has she C. isnt she D. is she析：陳述句部分含否定詞never,簡略問句部分要用肯定式，又因Kates是Kate has的縮寫，故選B。2. His uncle has already posted the photos to him. (改為否定句)His uncle _ posted the photos to him _. 析：already常用在肯定句中，yet常用在否定句、疑問句中，故填hasnt, yet。3. -Ann has gone to Shanghai. -So _her parents. A. has B. had C. did D. have析：so+助/系/情態(tài)動詞+主語結(jié)構(gòu)中的動詞形式應(yīng)與前句結(jié)構(gòu)中動詞形式保持一致，又后句的主語為her parents是復(fù)數(shù),故選D。二、考查其用法與標(biāo)志詞(一)當(dāng)句中有never, ever, just, already, yet, before等時，常用現(xiàn)在完成時。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; finished2. -_ 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：據(jù)yet和before可知,應(yīng)用現(xiàn)在完成時，故1題選D，2題選D。(二)當(dāng)句中有for +段時間或since +點時間等時，主句常用現(xiàn)在完成時，謂語動詞必須是延續(xù)性動詞，若是非延續(xù)性動詞，要改為延續(xù)性動詞或表狀態(tài)的詞(短語)。如：1. His brother has been to Stone Forest twice_he came to Yunnan. A. after B. before C. since D. for析：主句用的是現(xiàn)在完成時，而從句用的是一般過去時，故選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均為非延續(xù)性動詞，在肯定句中不與表段時間的短語連用，故選D。3. I_a letter from him since he left. A. didnt receive B. havent got C. didnt have D. havent heard析：據(jù)since可知，應(yīng)排除A、C，hear from sb.=receive/get/have a letter from sb.意為收到某人的來信，故選B。三、考查have/has been (to, in)/have/has gone (to)的區(qū)別。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：據(jù)句中的have，排除A，B項意為去某地了，C項意為一直呆在某地，D項意為去過某地，符合題意，故選D。2. My parents _ Shangdong for ten years. A. have been in B. have been to C. have gone to D. have been析：本題句中有for+段時間結(jié)構(gòu)，據(jù)此可排除C，B項意為去過某地，不合題意，D項缺介詞，故選A。四、考查現(xiàn)在完成時與其他時態(tài)的聯(lián)系和區(qū)別。如：1. Suns aunt has gone there for ten years.(改成正確的句子)析：非延續(xù)性動詞與段時間連用時，除了把非延續(xù)性動詞改成延續(xù)性動詞外，還可把動詞改為一般過去時或借助句型Its +段時間+since+從句進(jìn)行句子轉(zhuǎn)換。故答案為：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.(改為同義句)_more than ten years _Susan _to this city. 析：據(jù)上題分析，且since引導(dǎo)的從句要用一般過去時，故填I(lǐng)t is, since, came。3. I wont go to the concert because I _my ticket. A. lost B. dont lose C. have lost D. is coming析：因我丟了票的動作發(fā)生在過去，而且對現(xiàn)在造成了我不能參加音樂會的結(jié)果，符合現(xiàn)在完成時所表示的含意，故選C?，F(xiàn)在完成時專項練習(xí)題及答案一、單項選擇。1、Both his parents look sad .

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. 5、She has been to Shanghai. 6、Where has he been these days？(UNIT2)過去進(jìn)行時（注意when while as引導(dǎo)的時間狀語從句。）(UNIT3)被動語態(tài)復(fù)習(xí)“三步曲”被動語態(tài)是動詞語態(tài)的一種形式,表示主語是動作的承受者。在歷年的中考題中,都有一定數(shù)量的考查被動語態(tài)的題目。因此,有必要對被動語態(tài)進(jìn)行系統(tǒng)復(fù)習(xí)。第一曲:掌握被動語態(tài)的結(jié)構(gòu)被動語態(tài)由助動詞+及物動詞的過去分詞構(gòu)成。不同時態(tài)的被動語態(tài)的差異主要體現(xiàn)在助動詞be的變化上,同時助動詞be還要在人稱和數(shù)上與主語保持一致?，F(xiàn)將初中階段常見的幾種時態(tài)的被動語態(tài)總結(jié)如下:1.一般現(xiàn)在時的被動語態(tài):am/is/are+done(指及物動詞的過去分詞,下同)如:English is used all over the world.2.一般過去時的被動語態(tài):was/were+done如: The picture was painted two years ago.3.現(xiàn)在進(jìn)行時的被動語態(tài):am/is/are+being+done如: The flowers are being watered by them now. 4.現(xiàn)在完成時的被動語態(tài):have(has)+been+done如:The room has been cleaned.5.一般將來時的被動語態(tài):will/be going to+be+done如:The work will be finished tomorrow.6.含有情態(tài)動詞的被動語態(tài):情態(tài)動詞+be+done如:Your homework must be handed in today.其它幾種特殊句型：It is said that . It is well known that . It is reported that.have sth done 第二曲:掌握主動語態(tài)變被動語態(tài)的方法把主動語態(tài)變?yōu)楸粍诱Z態(tài)時,應(yīng)走好以下三步:1)主動語態(tài)的賓語變?yōu)楸粍诱Z態(tài)的主語; 2)主動語態(tài)的謂語動詞由主動語態(tài)形式變?yōu)楸粍诱Z態(tài)形式; 3)主動結(jié)構(gòu)的主語變?yōu)榻樵~by的賓語,組成介詞短語,放在被動結(jié)構(gòu)的謂語動詞之后。在無須說明動作的執(zhí)行者或只強(qiáng)調(diào)動作的承受者時,by短語可以省略。請看示范:主動語態(tài):My brother repaired that bike yesterday. 主語 謂語動詞 賓語其余部分被動語態(tài):That bike was repaired (by my brother) yesterday. 主語 謂語動詞 by+賓語其余部分對于主動語態(tài)變?yōu)楸粍诱Z態(tài)方法的考查,主要在句型轉(zhuǎn)換題目中出現(xiàn)。只要能夠按照上面介紹的方法去做,一般是能夠做對的。第三曲:注意主動語態(tài)變?yōu)楸粍诱Z態(tài)的幾種特殊句型1.含有短語動詞的被動語態(tài)一般來說,只有及物動詞才有被動語態(tài)。另外,許多不及物動詞加上介詞或副詞構(gòu)成的短語動詞,相當(dāng)于及物動詞,后面也可加賓語。在變被動語態(tài)時,注意不可丟掉后面的介詞或副詞,常見的這類短語動詞有: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.含有雙賓語的動詞的被動語態(tài)含有雙賓語的主動句改為被動句時,應(yīng)將其中一個賓語改為被動結(jié)構(gòu)的主語,另一個賓語仍保留在原處。一種情況是把間接賓語(指人)變?yōu)橹髡Z,直接賓語(指物)不變。另一種情況是把直接賓語(指物)變?yōu)橹髡Z,間接賓語(指人)不變,這時,間接賓語前通常加介詞to,有時加for。如:My father gave me a new book on my birthday.I was given a new book (by my father) on my birthday. (間接賓語作了主語)A new book was given to me (by my father) on my birthday. (直接賓語作了主語)3.帶有復(fù)合賓語的動詞的被動語態(tài)帶有復(fù)合賓語(賓語和賓語補足語)的主動語態(tài)變?yōu)楸粍诱Z態(tài)時,只把賓語變?yōu)楸粍诱Z態(tài)的主語,原來的賓語補足語不動。同時,如果賓語補足語是省略to的動詞不定式,變?yōu)楸粍诱Z態(tài)時,必須加上不定式符號to,這類動詞有make, let, see, hear, watch等。如:We find English very useful. English is found very useful. 賓語賓補I often hear him sing in his room. He is often heard to sing in his room. 賓語 賓補4.有的動詞的主動形式可以表示被動意義,這類動詞有: wash, sell, smell, taste, sound, feel等。如:The books sell well. The food tastes good.以上四種情況在中考題目中經(jīng)常出現(xiàn),同學(xué)們在碰到類似題目時,應(yīng)首先分析屬于哪種情況,然后再根據(jù)掌握的知識來做題。二、被動語態(tài)考點歸納1. 主動語態(tài)改為被動語態(tài)時，被動語態(tài)應(yīng)和主動語態(tài)的時態(tài)保持一致。如：We speak English . （改為被動語態(tài)） English _ _ by us. 分析此句主動語態(tài)為一般現(xiàn)在時態(tài)，被動語態(tài)也應(yīng)用一般現(xiàn)在時態(tài)，因此，答案應(yīng)是is spoken。2. 注意被動語態(tài)的謂語結(jié)構(gòu)。一般現(xiàn)在時是：am / is / are + p.p ；一般過去時是：was / were + p.p ；現(xiàn)在完成時是：have / has / been + p.p；現(xiàn)在進(jìn)行時是：am / is / are / + being + p.p；含有情態(tài)動詞的是：情態(tài)動詞be + p.p。有詩曰：被動語態(tài)須注意，謂語不離“be”“p.p”。主謂一致別忘記，“進(jìn)行”易丟一個“be”。（注：p.p過去分詞）。如：We must take good care of our eyes. （改為被動語態(tài)） Our eyes must _ _ good care of. 分析此句中含有情態(tài)動詞must，那么，我們根據(jù)“情態(tài)動詞be+p.p.”的公式可知，答案應(yīng)是be taken。3. 注意句中主謂語的一致關(guān)系。如：Tea _ （grow）in southeast of China and India. 分析此句中主語tea是不可數(shù)名詞，作主語時謂語動詞應(yīng)用單數(shù)形式。而此句說明的又是一自然現(xiàn)象，因此就應(yīng)用一般現(xiàn)在時態(tài)。所以，答案應(yīng)是is grown。4. 注意復(fù)合賓語的變化。如：They couldn”t make the cow go. （改為被動語態(tài)）分析the cow go 在句中作make的復(fù)合賓語。一般情況下，變?yōu)楸粍诱Z態(tài)后，賓語補足語的結(jié)構(gòu)形式、所處位置原封不動地保存下來，但make / have / let / see / watch / hear 等后原可省的to要還原回來。顯然，此句中，the cow go 中省去的to應(yīng)還原回來，因此答案應(yīng)是The cow couldn”t be made to go. 5. 注意雙賓語的變化。如：Mr Smith showed the students two pictures yesterday . （改為被動語態(tài)）Two pictures _ _ _ the students by Mr Smith. 分析變?yōu)楸粍诱Z態(tài)時，雙賓語中的任何一個皆可變?yōu)橹髡Z，一般變直接賓語，但間接賓語前必須加上介詞to或for。此句中顯然是把直接賓語變?yōu)楸粍诱Z態(tài)的主語，那么，間接賓語前須加上介詞to，所以答案應(yīng)是were shown to。6. 注意短語動詞中的“小詞”。如：The old men and the children _ in our country. A. must take good care B. must be taken good careC. must be taken good care of D. must take good care of 分析短語動詞是一個不可分割的整體，應(yīng)當(dāng)做一個詞來看待，變成被動語態(tài)后，“小詞”不能丟棄。因此，此題答案應(yīng)是C。被動語態(tài)專項練習(xí)1.Howlong_atthisjob?
