人教版八年級(jí)下學(xué)期英語(yǔ)語(yǔ)法講解

1、八年級(jí)下學(xué)期英語(yǔ)語(yǔ)法講解(UNIT1)現(xiàn)在完成時(shí)的重點(diǎn)和難點(diǎn)一、現(xiàn)在完成時(shí)的“完成用法”和“未完成用法”1.現(xiàn)在完成時(shí)的"完成用法" 現(xiàn)在完成時(shí)的"完成用法"指的是動(dòng)作發(fā)生在過(guò)去某一時(shí)刻并已結(jié)束，但該動(dòng)作對(duì)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(dòng)作結(jié)束于過(guò)去，但說(shuō)明的是現(xiàn)在的情況-燈現(xiàn)在不亮了。)現(xiàn)在完成時(shí)"完成用法"的特點(diǎn)是動(dòng)作不延續(xù)，因此，該時(shí)態(tài)只能與表示不定的過(guò)去時(shí)間狀語(yǔ)(如：already，yet，before，recently等)、頻度時(shí)間狀語(yǔ)(

2、如：never，ever，once等)、包括現(xiàn)在時(shí)刻在內(nèi)的時(shí)間狀語(yǔ)(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(shí)的"未完成用法" 現(xiàn)在完成時(shí)的"未完成用法"指的是動(dòng)作開(kāi)始于過(guò)去某一時(shí)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(lái)，他一直住在這兒。(動(dòng)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

3、 for more than 5 years.我在部隊(duì)已經(jīng)呆了五年多了。(動(dòng)作開(kāi)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(gè)表示一段時(shí)間的狀語(yǔ)(由since或for引導(dǎo))，或表示與現(xiàn)在時(shí)刻相連的時(shí)間狀語(yǔ)(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(méi)有他的任何消息。 注意：(1)現(xiàn)在完成時(shí)的未完成用法只適用于延續(xù)性動(dòng)詞，不可用于終止性動(dòng)詞，即瞬間完成或延續(xù)時(shí)間很短的動(dòng)詞。如：come，go，arrive，leave，join，become，die等。(2)現(xiàn)在完

4、成時(shí)常見(jiàn)兩種句型：主語(yǔ)have / has beenfor短語(yǔ) It is一段時(shí)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(dòng)詞和終止性動(dòng)詞的概念英語(yǔ)中，動(dòng)詞按其動(dòng)作發(fā)生的方式、動(dòng)作發(fā)生過(guò)程的長(zhǎng)短，可分為延續(xù)性動(dòng)詞和終止性動(dòng)詞。延續(xù)性動(dòng)詞表示能夠延續(xù)的動(dòng)作，這種動(dòng)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, wat

5、ch, sing, read, sleep, live, stay等。終止性動(dòng)詞也稱非延續(xù)性動(dòng)詞、瞬間動(dòng)詞或短暫性動(dòng)詞，表示不能延續(xù)的動(dòng)作，這種動(dòng)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(dòng)詞的用法特征櫻·Prayer 20:58:281.延續(xù)性動(dòng)詞可以用于現(xiàn)在完成時(shí)，其完成時(shí)態(tài)可與表示"段時(shí)間"的狀語(yǔ)連用。表示"段時(shí)間"的短語(yǔ)有：for two years, during the pa

6、st three years, since last year, how long等。如：I have learned English since I came here.自從我來(lái)到這兒就學(xué)英語(yǔ)了。2.延續(xù)性動(dòng)詞不能與表示短暫時(shí)間的"點(diǎn)時(shí)間"狀語(yǔ)連用。如：It raind at eight yesterday morning.(誤) rain為延續(xù)性動(dòng)詞，而at eight表示"點(diǎn)時(shí)間"，前后顯然矛盾。如果用延續(xù)性動(dòng)詞表示一瞬間的動(dòng)作，可以借助come, begin, get等終止性動(dòng)詞來(lái)表示。上句可改為：It began to rain at eigh

7、t yesterday morning.(正)又如：-When did you get to know Jack?-Two years ago.-Then you've known each other for more than two years.-That's right.5、終止性動(dòng)詞的用法特征1.終止性動(dòng)詞可用來(lái)表示某一動(dòng)作完成，因此可用于現(xiàn)在完成時(shí)。如：The train has arrived.火車(chē)到了。Have you joined the computer group? 你加入電腦小組了嗎？2.終止性動(dòng)詞表示的動(dòng)作極其短暫，不能持續(xù)。因此，不可與表示一段時(shí)間的

8、狀語(yǔ)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(lái)這兒五天了。 誤：He has come here for five days.正：He

9、 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(dòng)詞，不能與表示"段時(shí)間"的狀語(yǔ)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(dòng)詞轉(zhuǎn)換為相應(yīng)的延續(xù)性動(dòng)詞，如上面兩例中的第一種正確表達(dá)方式。下面列舉

10、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(shí)間"的狀語(yǔ)改為表示過(guò)去確定時(shí)間的狀語(yǔ)，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(shí)間+since."表達(dá)原意，如

11、上面兩例中的第三種正確表達(dá)方式。(4)用句型"時(shí)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(dòng)詞可用于現(xiàn)在完成時(shí)否定式中，成為可以延續(xù)的狀態(tài)，因而可與表示一段時(shí)間的狀語(yǔ)連用。如：He hasn't left here since 1986.I haven't heard from my father for two weeks.4.終止性動(dòng)詞的否定式與until/till連用，構(gòu)成"not+終止性動(dòng)詞+until/till ."的句型，意為"直到才"。如：You can

12、't leave here until I arrive.直到我到了，你才能離開(kāi)這里。櫻·Prayer 20:58:44I will not go to bed until I finish drawing the picture tonight.今天晚上直到我畫(huà)完畫(huà)，我才上床睡覺(jué)。5.終止性動(dòng)詞可以用于when引導(dǎo)的時(shí)間狀語(yǔ)從句中，但不可以用于while引導(dǎo)的時(shí)間狀語(yǔ)從句中。when表示的時(shí)間是"點(diǎn)時(shí)間"(從句謂語(yǔ)動(dòng)詞用終止性動(dòng)詞)，也可以是"段時(shí)間"(從句謂語(yǔ)動(dòng)詞用延續(xù)性動(dòng)詞)。而while表示的是一個(gè)較長(zhǎng)的時(shí)間或過(guò)程，從句謂語(yǔ)動(dòng)詞

13、用延續(xù)性動(dòng)詞。如：When we reached London, it was twelve o'clock. (reach為終止性動(dòng)詞)Please look after my daughter while/when we are away. (be away為延續(xù)性動(dòng)詞短語(yǔ))6.終止性動(dòng)詞完成時(shí)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(shí)與一般過(guò)去時(shí)的區(qū)別1.

14、 一般過(guò)去時(shí)表示過(guò)去某個(gè)時(shí)間發(fā)生的事、存在的狀態(tài)或經(jīng)常發(fā)生的動(dòng)作。說(shuō)話的側(cè)重點(diǎn)只在于陳述一件過(guò)去的事情，不強(qiáng)調(diào)對(duì)"現(xiàn)在"產(chǎn)生的影響。如：He visited Guilin in 1998.他1998年參觀過(guò)桂林。(只說(shuō)明去桂林的時(shí)間)2. 現(xiàn)在完成時(shí)表示動(dòng)作發(fā)生在過(guò)去，對(duì)現(xiàn)在造成了影響或產(chǎn)生了結(jié)果。不與確定的過(guò)去時(shí)間狀語(yǔ)連用。如：Jill has bought a new computer.吉爾買(mǎi)了一臺(tái)新電腦。(著重點(diǎn)是現(xiàn)在有了一臺(tái)新電腦)3. 兩種時(shí)態(tài)的區(qū)分(1)一般過(guò)去時(shí)的謂語(yǔ)動(dòng)詞用過(guò)去式，而現(xiàn)在完成時(shí)的謂語(yǔ)基本構(gòu)成是"助動(dòng)詞have /has +過(guò)去分詞&q

15、uot;。如：The film started at 7 oclock.     He has been a teacher for many years.(2)一般過(guò)去時(shí)通常與表示過(guò)去的時(shí)間狀語(yǔ)連用。如：yesterday, last week, two years ago, just now, in 2002等；而現(xiàn)在完成時(shí)則常與just, already, ever, never等副詞和these days, this week, since., for.等表示一段時(shí)間的狀語(yǔ)連用?？纯匆韵碌膸捉M句子，有什么區(qū)別？ Have you seen the

16、 film?(A) Did you see the film?(B)說(shuō)明 你看過(guò)這部電影嗎？(A)句強(qiáng)調(diào)的是被問(wèn)者對(duì)劇情是否了解；(B)句強(qiáng)調(diào)的是看這部電影的動(dòng)作是否發(fā)生過(guò)，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(shuō)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(duì)現(xiàn)在產(chǎn)生了某種影響；(B)句單純的詢問(wèn)做這件事的方式。 He has lived in Beijing for 8 years.(A)      He lived in

17、Beijing for 8 years.(B)說(shuō)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(huì)繼續(xù)在北京住下去。(B)句講的是他在北京住過(guò)8年，現(xiàn)在不在北京了。三、現(xiàn)在完成時(shí)考點(diǎn)例析現(xiàn)在完成時(shí)是較難掌握、中考考查較多的時(shí)態(tài)。涉及的考點(diǎn)有：櫻·Prayer 20:58:59一、考查其構(gòu)成"助動(dòng)詞have (has) +動(dòng)詞過(guò)去分詞"構(gòu)成現(xiàn)在完成時(shí)。如：1. Kate's never seen Chinese films，_ ? A. hasn't she B. has she C. isn't she D. is sh

18、e析：陳述句部分含否定詞never,簡(jiǎn)略問(wèn)句部分要用肯定式，又因Kate's是Kate has的縮寫(xiě)，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(wèn)句中，故填hasn't, yet。3. -Ann has gone to Shanghai. -So _her parents.   A. has B. had C. did D. have析：&qu

19、ot;so+助/系/情態(tài)動(dòng)詞+主語(yǔ)"結(jié)構(gòu)中的動(dòng)詞形式應(yīng)與前句結(jié)構(gòu)中動(dòng)詞形式保持一致，又后句的主語(yǔ)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(shí)，常用現(xiàn)在完成時(shí)。如：1. -Mum, may I go out and play basketball? -_you_ your homework yet? A. Do; finish   B. Are; finishing   C. Did; finish   

20、 D. Have; finished2. -_ you _anywhere before? -Yes, but I can't 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(shí)，故1題選D，2題選D。(二)當(dāng)句中有"fo

21、r +段時(shí)間"或"since +點(diǎn)時(shí)間"等時(shí)，主句常用現(xiàn)在完成時(shí)，謂語(yǔ)動(dòng)詞必須是延續(xù)性動(dòng)詞，若是非延續(xù)性動(dòng)詞，要改為延續(xù)性動(dòng)詞或表狀態(tài)的詞(短語(yǔ))。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(shí)，而從句用的是一般過(guò)去時(shí)，故選C。2. Tom_the CD player for tw

22、o 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(dòng)詞，在肯定句中不與表"段時(shí)間"的短語(yǔ)連用，故選D。3. I_a letter from him since he left. A. didn't receive   B. haven't got   C. didn't have 

23、0; D. haven't 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(lái)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 

24、;    C. been in      D. been to析：據(jù)句中的have，排除A，B項(xiàng)意為"去某地了"，C項(xiàng)意為"一直呆在某地"，D項(xiàng)意為"去過(guò)某地"，符合題意，故選D。2. My parents _ Shangdong for ten years. 櫻·Prayer 20:59:26A. have been in    B. have been to    C. have g

25、one to     D. have been析：本題句中有"for+段時(shí)間"結(jié)構(gòu)，據(jù)此可排除C，B項(xiàng)意為"去過(guò)某地"，不合題意，D項(xiàng)缺介詞，故選A。四、考查現(xiàn)在完成時(shí)與其他時(shí)態(tài)的聯(lián)系和區(qū)別。如：1. Sun's aunt has gone there for ten years.(改成正確的句子)析：非延續(xù)性動(dòng)詞與"段時(shí)間"連用時(shí)，除了把非延續(xù)性動(dòng)詞改成延續(xù)性動(dòng)詞外，還可把動(dòng)詞改為一般過(guò)去時(shí)或借助句型"It's +段時(shí)間+since+從句"進(jìn)行句子轉(zhuǎn)換。故答

26、案為：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 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(guò)去時(shí)，故填I(lǐng)t is, since, came。3. I

27、 won't go to the concert because I _my ticket. A. lost   B. don't lose   C. have lost   D. is coming析：因我丟了票的動(dòng)作發(fā)生在過(guò)去，而且對(duì)現(xiàn)在造成了我不能參加音樂(lè)會(huì)的結(jié)果，符合現(xiàn)在完成時(shí)所表示的含意，故選C。(UNIT2)過(guò)去進(jìn)行時(shí)（注意when while as引導(dǎo)的時(shí)間狀語(yǔ)從句。）(UNIT3)被動(dòng)語(yǔ)態(tài)復(fù)習(xí)“三步曲”被動(dòng)語(yǔ)態(tài)是動(dòng)詞語(yǔ)態(tài)的一種形式,表示主語(yǔ)是動(dòng)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(dòng)語(yǔ)態(tài)的題

28、目。因此,有必要對(duì)被動(dòng)語(yǔ)態(tài)進(jìn)行系統(tǒng)復(fù)習(xí)。第一曲:掌握被動(dòng)語(yǔ)態(tài)的結(jié)構(gòu)被動(dòng)語(yǔ)態(tài)由"助動(dòng)詞+及物動(dòng)詞的過(guò)去分詞"構(gòu)成。不同時(shí)態(tài)的被動(dòng)語(yǔ)態(tài)的差異主要體現(xiàn)在助動(dòng)詞be的變化上,同時(shí)助動(dòng)詞be還要在人稱和數(shù)上與主語(yǔ)保持一致。現(xiàn)將初中階段常見(jiàn)的幾種時(shí)態(tài)的被動(dòng)語(yǔ)態(tài)總結(jié)如下:1.一般現(xiàn)在時(shí)的被動(dòng)語(yǔ)態(tài):am/is/are+done(指及物動(dòng)詞的過(guò)去分詞,下同)如:English is used all over the world.2.一般過(guò)去時(shí)的被動(dòng)語(yǔ)態(tài):was/were+done如: The picture was painted two years ago.3.現(xiàn)在進(jìn)行時(shí)的被動(dòng)語(yǔ)態(tài):am

29、/is/are+being+done如: The flowers are being watered by them now. 4.現(xiàn)在完成時(shí)的被動(dòng)語(yǔ)態(tài):have(has)+been+done如:The room has been cleaned.5.一般將來(lái)時(shí)的被動(dòng)語(yǔ)態(tài):will/be going to+be+done如:The work will be finished tomorrow.6.含有情態(tài)動(dòng)詞的被動(dòng)語(yǔ)態(tài):情態(tài)動(dòng)詞+be+done如:Your homework must be handed in today.其它幾種特殊句型：It is said that . 

30、0;       It is well known that .       It is reported that.have sth done     第二曲:掌握主動(dòng)語(yǔ)態(tài)變被動(dòng)語(yǔ)態(tài)的方法把主動(dòng)語(yǔ)態(tài)變?yōu)楸粍?dòng)語(yǔ)態(tài)時(shí),應(yīng)走好以下三步:1)主動(dòng)語(yǔ)態(tài)的賓語(yǔ)變?yōu)楸粍?dòng)語(yǔ)態(tài)的主語(yǔ); 2)主動(dòng)語(yǔ)態(tài)的謂語(yǔ)動(dòng)詞由主動(dòng)語(yǔ)態(tài)形式變?yōu)楸粍?dòng)語(yǔ)態(tài)形式; 3)主動(dòng)結(jié)構(gòu)的主語(yǔ)變?yōu)榻樵~by的賓語(yǔ),組成介詞短語(yǔ),放在被動(dòng)結(jié)構(gòu)的謂語(yǔ)動(dòng)詞之后。在無(wú)須說(shuō)明動(dòng)作的執(zhí)行者或只強(qiáng)調(diào)動(dòng)

31、作的承受者時(shí),by短語(yǔ)可以省略。請(qǐng)看示范:主動(dòng)語(yǔ)態(tài):My brother   repaired    that bike yesterday.       主語(yǔ)     謂語(yǔ)動(dòng)詞賓語(yǔ)其余部分被動(dòng)語(yǔ)態(tài):That bike    was repaired   (by my brother) yesterday.    主語(yǔ)    &

32、#160;  謂語(yǔ)動(dòng)詞       by+賓語(yǔ)其余部分對(duì)于主動(dòng)語(yǔ)態(tài)變?yōu)楸粍?dòng)語(yǔ)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(duì)的。第三曲:注意主動(dòng)語(yǔ)態(tài)變?yōu)楸粍?dòng)語(yǔ)態(tài)的幾種特殊句型1.含有短語(yǔ)動(dòng)詞的被動(dòng)語(yǔ)態(tài)一般來(lái)說(shuō),只有及物動(dòng)詞才有被動(dòng)語(yǔ)態(tài)。另外,許多不及物動(dòng)詞加上介詞或副詞構(gòu)成的短語(yǔ)動(dòng)詞,相當(dāng)于及物動(dòng)詞,后面也可加賓語(yǔ)。在變被動(dòng)語(yǔ)態(tài)時(shí),注意不可丟掉后面的介詞或副詞,常見(jiàn)的這類(lèi)短語(yǔ)動(dòng)詞有:take care of, look after, take off, look at, send for

33、, look up等。如:The old people should be taken good care of.2.含有雙賓語(yǔ)的動(dòng)詞的被動(dòng)語(yǔ)態(tài)含有雙賓語(yǔ)的主動(dòng)句改為被動(dòng)句時(shí),應(yīng)將其中一個(gè)賓語(yǔ)改為被動(dòng)結(jié)構(gòu)的主語(yǔ),另一個(gè)賓語(yǔ)仍保留在原處。一種情況是把間接賓語(yǔ)(指人)變?yōu)橹髡Z(yǔ),直接賓語(yǔ)(指物)不變。另一種情況是把直接賓語(yǔ)(指物)變?yōu)橹髡Z(yǔ),間接賓語(yǔ)(指人)不變,這時(shí),間接賓語(yǔ)前通常加介詞to,有時(shí)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

34、. (間接賓語(yǔ)作了主語(yǔ))A new book was given to me (by my father) on my birthday. (直接賓語(yǔ)作了主語(yǔ))3.帶有復(fù)合賓語(yǔ)的動(dòng)詞的被動(dòng)語(yǔ)態(tài)帶有復(fù)合賓語(yǔ)(賓語(yǔ)和賓語(yǔ)補(bǔ)足語(yǔ))的主動(dòng)語(yǔ)態(tài)變?yōu)楸粍?dòng)語(yǔ)態(tài)時(shí),只把賓語(yǔ)變?yōu)楸粍?dòng)語(yǔ)態(tài)的主語(yǔ),原來(lái)的賓語(yǔ)補(bǔ)足語(yǔ)不動(dòng)。同時(shí),如果賓語(yǔ)補(bǔ)足語(yǔ)是省略to的動(dòng)詞不定式,變?yōu)楸粍?dòng)語(yǔ)態(tài)時(shí),必須加上不定式符號(hào)to,這類(lèi)動(dòng)詞有make, let, see, hear, watch等。如:We find English very useful.

36、0;     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?cè)谂龅筋?lèi)似題目時(shí),應(yīng)首先分析屬于櫻·Prayer 20:59:33哪種情況,然后再根據(jù)掌握的知識(shí)來(lái)做題。二、被動(dòng)語(yǔ)態(tài)考點(diǎn)歸納1. 主動(dòng)語(yǔ)態(tài)改為被動(dòng)語(yǔ)態(tài)時(shí)，被動(dòng)語(yǔ)態(tài)應(yīng)和主動(dòng)語(yǔ)態(tài)的時(shí)態(tài)保持一致。如：We speak English . （改為被動(dòng)語(yǔ)態(tài)） English _ _ by us. 分析此句主動(dòng)語(yǔ)態(tài)為一般現(xiàn)在時(shí)態(tài)，被動(dòng)語(yǔ)態(tài)也應(yīng)用一般現(xiàn)在時(shí)態(tài)，因此，答案應(yīng)是is spoken。2. 注意被動(dòng)語(yǔ)態(tài)的謂語(yǔ)結(jié)構(gòu)。一般現(xiàn)在時(shí)是：am / is / are

37、+ p.p ；一般過(guò)去時(shí)是：was / were + p.p ；現(xiàn)在完成時(shí)是：have / has / been + p.p；現(xiàn)在進(jìn)行時(shí)是：am / is / are / + being + p.p；含有情態(tài)動(dòng)詞的是：情態(tài)動(dòng)詞be + p.p。有詩(shī)曰：被動(dòng)語(yǔ)態(tài)須注意，謂語(yǔ)不離“be”“p.p”。主謂一致別忘記，“進(jìn)行”易丟一個(gè)“be”。（注：p.p過(guò)去分詞）。如：We must take good care of our eyes. （改為被動(dòng)語(yǔ)態(tài)） Our eyes must _ _ good care of. 分析此句中含有情態(tài)動(dòng)詞must，那么，我們根據(jù)“情態(tài)動(dòng)詞be+p.p.”的公式可

38、知，答案應(yīng)是be taken。3. 注意句中主謂語(yǔ)的一致關(guān)系。如：Tea _ （grow）in southeast of China and India. 分析此句中主語(yǔ)tea是不可數(shù)名詞，作主語(yǔ)時(shí)謂語(yǔ)動(dòng)詞應(yīng)用單數(shù)形式。而此句說(shuō)明的又是一自然現(xiàn)象，因此就應(yīng)用一般現(xiàn)在時(shí)態(tài)。所以，答案應(yīng)是is grown。4. 注意復(fù)合賓語(yǔ)的變化。如：They couldn”t make the cow go. （改為被動(dòng)語(yǔ)態(tài)）分析the cow go 在句中作make的復(fù)合賓語(yǔ)。一般情況下，變?yōu)楸粍?dòng)語(yǔ)態(tài)后，賓語(yǔ)補(bǔ)足語(yǔ)的結(jié)構(gòu)形式、所處位置原封不動(dòng)地保存下來(lái)，但make / have / let / see / w

39、atch / hear 等后原可省的to要還原回來(lái)。顯然，此句中，the cow go 中省去的to應(yīng)還原回來(lái)，因此答案應(yīng)是The cow couldn”t be made to go. 5. 注意雙賓語(yǔ)的變化。如：Mr Smith showed the students two pictures yesterday . （改為被動(dòng)語(yǔ)態(tài)）Two pictures _ _ _ the students by Mr Smith. 分析變?yōu)楸粍?dòng)語(yǔ)態(tài)時(shí)，雙賓語(yǔ)中的任何一個(gè)皆可變?yōu)橹髡Z(yǔ)，一般變直接賓語(yǔ)，但間接賓語(yǔ)前必須加上介詞to或for。此句中顯然是把直接賓語(yǔ)變?yōu)楸粍?dòng)語(yǔ)態(tài)的主語(yǔ)，那么，間接賓語(yǔ)前須加上

40、介詞to，所以答案應(yīng)是were shown to。6. 注意短語(yǔ)動(dòng)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(yǔ)動(dòng)詞是一個(gè)不可分割的整體，應(yīng)當(dāng)做一個(gè)詞來(lái)看待，變成被動(dòng)語(yǔ)態(tài)后，“小詞”不能丟棄。因此，此題答案應(yīng)是C。櫻·P
