3.定語(yǔ)從句的簡(jiǎn)化表達(dá)

知識(shí)總結(jié)歸納

(一)定語(yǔ)從句的結(jié)構(gòu):在復(fù)合句中,修飾某個(gè)名詞或代詞的句子(做這個(gè)名詞或代詞的定語(yǔ))叫定語(yǔ)從句,定語(yǔ)從句一般放在被修飾的名詞或代詞后面,被修飾的名詞或代詞叫做定語(yǔ)從句的先行詞,它與定語(yǔ)從句之間要有一個(gè)詞連接,這個(gè)詞指代先行詞的內(nèi)容叫做關(guān)系詞(關(guān)系代詞或關(guān)系副詞:that,which,who,whose,when,where,why)。先行詞在定語(yǔ)從句中充當(dāng)主語(yǔ),賓語(yǔ),時(shí)間,地點(diǎn),原因狀語(yǔ)。

結(jié)構(gòu):先行詞+關(guān)系詞+定語(yǔ)從句。

1.Thereshesawawallofwaterthatwasquicklyadvancingtowardsher.

2.InJapan,someonewhoseesanotherpersonmakingthegesturewillthinkitmeansmoney.

3.Athemeparkisacollectionofrides,exhibitionsorotherattractionsthatarebasedonacommontheme.

5.Visitorscangoonexcitingrideswheretheycanfeelwhatitisliketodothethingstheyhaveseentheirheroesdointhemovie.

6.OprahWinfreyisablackwomanwhoserisetofameisaninspiringstory.

(二)定語(yǔ)從句分為限定性定語(yǔ)從句和非限定性定語(yǔ)從句:

限定性定語(yǔ)從句:從句對(duì)先行詞進(jìn)行必要的描述或說明,缺少它,則句義顯得不完整,從句與先行詞緊密相連。

非限定性定語(yǔ)從句:對(duì)先行詞進(jìn)行補(bǔ)充說明,解釋,它與先行詞之間有逗號(hào)隔開。

1.Beforeshecouldmove,sheheardaloudnoise,whichgrewtoaterribleroar.

2.Treeaftertreewentdown,cutdownbythewater,whichmusthavebeenthreemetersdeep.

3.Flora,whosebeautifulhairanddresswereallcoldandwet,startedcrying.

4.Theirtalkincludesrhythmandrhymingwordsaswellastonguetwisters,whichoftenmaketheaudienceapplaud.

(三)關(guān)系詞前面可以根據(jù)定語(yǔ)從句的內(nèi)容加上一些介詞,這些關(guān)系詞在介詞后面常用which或whom.

1.TherewasamanwithwhomIwouldhavetoworktogetherandfinallythemanagerofthecompany.

2.Manypeoplewhosawthefilmwereafraidtoswimintheseawhentheyrememberedthescenesinwhichpeoplewereeatenbytheshark.

知識(shí)重點(diǎn)與難點(diǎn)

(一)當(dāng)先行詞有最高級(jí),序數(shù)詞修飾,是不定代詞,或是all,no,only等形式時(shí),關(guān)系代詞一般用that,而不能用which。

1.TheTitanicwasthelargestshipthathadeverbeenbuiltatthattime.

2.Thereisonethingthatkeepsworryingme.

(二)當(dāng)先行詞是表示時(shí)間,地點(diǎn),原因的詞時(shí),關(guān)系詞用when,where,why還有which,that

1.I’mverygladtoreturntomyhometownwhereIhadlivedfor10years.

2.ThisismyhometownwhichIusedtotalkabouttoyou.

3.IthinkIcanunderstandthereasonwhyhedidn’ttellthetruthtome.

4.Noonebelievesthereasonthathegaveusabouthisabsenceatthemeeting.

(三)定語(yǔ)從句的簡(jiǎn)化表達(dá):

1.ThemanwhoissittingontheplatformisaprofessorfromWuhanUniversity.

2.Theletterthatwasmailedlastnightwillreachhimtomorrow.

3.Thequestionthatisbeingdiscussedisveryimportant.

4.Youarewelcometoapartytobegiveninourclassat7:45.

說明:以上的定語(yǔ)從句部分可以用更加簡(jiǎn)單的非謂語(yǔ)形式表達(dá)出來:

1.ThemansittingontheplatformisaprofessorfromWuhanUniversity.

2.Thelettermailedlastnightwillreachhimtomorrow.

3.Thequestionbeingdiscussedisveryimportant.

4.Youarewelcometoapartytobegiveninourclassat7:45.

說明:修飾一個(gè)名詞除了后面用定語(yǔ)從句以外,還可以用非謂語(yǔ)動(dòng)詞形式:doing短語(yǔ),done短語(yǔ),beingdone短語(yǔ),tobedone短語(yǔ)修飾。其結(jié)構(gòu)和意思如下:

1.被修飾名詞+doing短語(yǔ):正在做….的人/正在發(fā)生的事。

2.被修飾名詞+done短語(yǔ):被…..的人/事

3.被修飾名詞+beingdone短語(yǔ):正在被…..的人/事

4.被修飾名詞+tobedone短語(yǔ):將要被…..的人/事

(1)Doyouknowthemantalkingtomysister?

(2)The“crazy”gesture,movingtheindexfingerinacircleinfrontoftheear,means“youhaveaphonecall”inBrazil.

(3)Didyouseethatcarbeingrepaired?

(4)Inacamera,thelensmustbefocusedontheobjecttobephotographed.

(5)Thestudentstoattendthemeetingwillarriveheretomorrow.

(6)GoodsimportedfromabroadarenotalwaysbetterthanthosemadeinChina.

(7)TheYellowRiver,saidtobe“themotherriver”runsacrossChinalikeahugedragon.

總結(jié):以上做定語(yǔ)的那些短語(yǔ)就是英語(yǔ)語(yǔ)法中所說的分詞,不定式的各種形式作定語(yǔ)。

1.這些短語(yǔ)作定語(yǔ)應(yīng)放在被修飾名詞的后面。如果單獨(dú)一個(gè)V-ing或V-ed形式作定語(yǔ),則可以放在被修飾名詞前面。

2.分詞作定語(yǔ)時(shí),其動(dòng)作應(yīng)與全句動(dòng)作同時(shí)發(fā)生。V-ing表示主動(dòng)意義和正在做,V-ed表示被動(dòng)意義。beingdone表示正在被做的

3.不定式作定語(yǔ)表示將要發(fā)生的,tobedone表示將要被做的

情態(tài)動(dòng)詞

1.情態(tài)動(dòng)詞的推測(cè)表達(dá)

2.情態(tài)動(dòng)詞表達(dá)虛擬語(yǔ)氣

3.某些情態(tài)動(dòng)詞的特殊用法

知識(shí)重點(diǎn)與難點(diǎn)總結(jié)

知識(shí)重點(diǎn):

情態(tài)動(dòng)詞在表達(dá)推測(cè)意義的句子中的運(yùn)用:

(一)用情態(tài)動(dòng)詞表達(dá)事實(shí)的推測(cè)。can,could,might,may,must可以用來表達(dá)對(duì)事實(shí)的推測(cè)。根據(jù)說話人對(duì)事實(shí)的把握性大小,must表示“肯定…”,may/might/can/could表示“可能……”,must只用于肯定句中,may/might的否定式maynot/mightnot表示“可能不……”,而can/could可以用于疑問句,表示“可能,可能……嗎?”,其否定式can’t/couldn’t表示“不可能”。用情態(tài)動(dòng)詞可以對(duì)現(xiàn)在或過去的事實(shí)進(jìn)行推測(cè)。對(duì)不同的時(shí)間內(nèi)容推測(cè)有不同的結(jié)構(gòu)。

(二)對(duì)現(xiàn)在的事實(shí)進(jìn)行推測(cè):

主要結(jié)構(gòu):…must/may/might+動(dòng)詞原形

be+名詞/形容詞/介詞短語(yǔ)

be+doing

例句:

1.YoumustbeJeanne.I’mMathildeLoisel.Weusedtoknoweachotherverywell.

2.Theymustbeinbedalreadyatthistimeofthenight.

3.Theteachermustbejoking.

4.Fredaisn’tinclass.Shemustbesick.

5.Theremustbesomethingwrong.

6.Shemightbeveryclever,butshehasn’tgotmuchcommonsense.

7.Hemaybearrivingthisevening.

8.Hemaybetravelingaroundtheworld.

9.Thekeyscan’tbeintheroom.Ihavejustsearcheditverycarefully.

10.Canthenewsbetrue?

(三)對(duì)過去的事實(shí)進(jìn)行推測(cè):結(jié)構(gòu):情態(tài)動(dòng)詞+havedone/been+名詞/形容詞/介詞短語(yǔ)

例句:

1.Mrs.Longmansmusthavebeenaprettygirlinheryouth.

2.Hecouldn’thaveseenAnnayesterday.She’sgoneabroad.

3.IthinkImusthaveleftmyglassesinthelibrary.

4.Hemighthaveoversleptagain.

5.WherecanTomhavegone?

情態(tài)動(dòng)詞表達(dá)虛擬語(yǔ)氣:表達(dá)“本來…”,“不然早就…”。這是情態(tài)動(dòng)詞的一種虛擬語(yǔ)氣用法。表示說話人所講的與所發(fā)生的事實(shí)相反。表達(dá)了說話人的埋怨,后悔的語(yǔ)氣。其結(jié)構(gòu)是在一些情態(tài)動(dòng)詞后面加havedone結(jié)構(gòu)。根據(jù)要表達(dá)的意思,有如下結(jié)構(gòu):

shouldhavedone/oughttohavedone:本應(yīng)該……

shouldn’thavedone/oughtn’ttohavedone:本不該……

couldhavedone:本來可以……

needn’thavedone:本來沒必要……

wouldliketohavedone:本來很想……

wouldrathernothavedone:本來不愿意……

could/might/havedone:不然早就……

例句:

1.Youshouldn’thavelaughedathismistakes.

2.Youcouldhavetoldusearlier.

3.Ioughttohaveboughtthatdictionarylastweek.

4.Yououghtnottohavespentsomuchtimeinreadingnovels.

5.Weneednothavebeeninatearinghurrytocatchthetrain.

6.Theywouldliketohaveseenthatfilmlastfilm.

7.Ifhehadgivenmehisnumber,Icouldhavetelephonedhim.

8.Theymighthavebeenfrozentodeathbutfortherescueintime.

知識(shí)難點(diǎn):

某些情態(tài)動(dòng)詞的特殊用法:

need和dare的兩種形式的用法

need和dare可以用做實(shí)義動(dòng)詞,后面接不定式(todo)結(jié)構(gòu),在疑問句和否定句中,加助動(dòng)詞do/does/did/或don’t/doesn’t/didn’t。作為情態(tài)動(dòng)詞使用時(shí),主要用于疑問句和否定句中。情態(tài)動(dòng)詞needn’t(沒有必要,不必)相當(dāng)于don’thaveto

例句:

1.Itiscold,youneedtowearsomewarmclothes.

2.NeedIstayherewithyouforawhile?Thankyou,youneedn’t.

3.Howdareyouspeaktoparentslikethat?

注意:

句型Idaresay+從句。意思是:我肯定……=I’msure或Thereisnodoubtthat+從句。

例句:

IdaresaythatmyunclewillgetthemoneyifIdie.

will和would

表示“意志”或“愿意”,would則指過去愿意做……

例句:

1.Hesaidthathewouldhelpus.

2.Youmaytelephoneifyouwillacceptthisjob.

would可以表達(dá)“過去習(xí)慣做……”類似于“usedtodo”

例句:

1.Whenwewerechildren,wewouldgoswimmingeverysummerinthatriver.

表示請(qǐng)求,固定的句型:Will/Wouldyoupleasedo…?/Wouldyouliketodo…?

例句:Will/Wouldyoupleasegivehimamessagewhenyouseehim?

shall

1.用于第一,三人稱,表示“請(qǐng)求”;“建議”或“推薦”

例句:

1.Shallwestartthemeetingnow?

2.ShallIwatchTVnow?

3.Shallmysoncarrythecaseforyou?

2.用于第二人稱,表示“命令,“要求”,“許諾”

例句:

1.Youshalltakewhateveryoulike.

2.Youshallnotgotothepartywithmeifyoumakesomuchnoiseagain.

在表示推測(cè)的否定句或疑問句中,常用can/can’t/could/couldn’t表示,意思是:“可能…嗎?”;“…不可能…”。而不能使用mustn’t或must等詞。

【典型例題】

1.—Doyouthinkhewilldomeafavor?

—AsfarasIknow,heisthelastonetohelpothers.He_____bepreparedtogiveyouahand,though.

A.mightB.mustC.canD.should

分析:本題考查情態(tài)動(dòng)詞推測(cè)性用法。根據(jù)heisthelastonetohelpothers.(他是最不可能幫助別人的人),既然如此,那么“幫助你”的可能性也就最小了。答案為A

2.—Look,someoneiscoming.Guesswhoit____be?

—Ithinkit___beTom.

—Idon’tthinkit___be____.

A.can;must;can;heB.may;can;must;him

C.must;can;must;hisD.might;must;can;himself

分析:根據(jù)備選答案。can表示推測(cè)時(shí)用于疑問句或否定句中。本題首句就應(yīng)該是Guesswhocanitbe?第二句應(yīng)該是IthinkitmustbeTom.(說話人十分肯定)。第三句表達(dá)了說話人對(duì)前一個(gè)人的否定。即:Idon’tthinkitcanbehim/he.(不可能是他)。答案為A

3.—DoyouknowMs.Wanglikeswalkingaftersupper?

—Sure.She____aroundthecampusnow.

A.mustbewalkingB.mustwalk

C.maywalkD.maybewalking

分析:關(guān)鍵詞Sure告訴我們說話人的口氣十分肯定。根據(jù)句子語(yǔ)境:她此刻肯定正在校園散步呢。mustbedoing表示肯定正在做。答案為A

4.—IstayedatahotelinNewYork.

—Oh,didyou?You_____withBarbara.

A.couldhavestayedB.couldstayC.wouldsayD.musthavestayed

分析:首句說:我在紐約住在一家賓館里。在此ahotel是泛指。所以D選項(xiàng)不合題意。第二句在說:你本來可以和Barbara.住在一起的。Couldhavedone表示:本來可以。答案為A

5.Whydidn’tyoutellmetherewasnomeetingtoday?I_____allthewayherethroughtheheavysnow.
