nydeerthattheyateupallthewildroses.Hehassolittletimethathecantgotothecinemawithyou.,難點(diǎn)鏈接,(3)sothat和such.that在由so.that引導(dǎo)的結(jié)果狀語從句中，so是副詞，與形容詞連用。其結(jié)構(gòu)是:“.so+形容詞（副詞）+that+從句”。例如：Hewassogladthathecouldntsayaword.Thehallissobigthatitcanhold2,000people.Motherlivessofarawaythatwehardlyeverseeher.在由suchthat引導(dǎo)的結(jié)果狀語從句中，such是形容詞，它修飾的可以是單數(shù)或復(fù)數(shù)可數(shù)名詞，也可以是不可數(shù)名詞；名詞前面可以帶形容詞，也可不帶。如果是單數(shù)可數(shù)名詞，前面需加不定冠詞a或an。例如：Itwassuchahotdaythatnobodywantedtodoanything.Hehadsuchlongarmsthathecouldalmosttouchtheceiling.Hemadesuchrapidprogressthathedidverywellinthemid-term.有時(shí)上述兩種結(jié)構(gòu)是可以互換的。例如：Itwassuchawonderfulfilmthatallofuswantedtoseeitagain.=Thefilmwassowonderfulthatallofuswantedtoseeitagain.Itissuchanimportantmatchthatnobodywantstomissit.=Thematchissoimportantthatnobodywantstomissit.,難點(diǎn)鏈接,5.原因狀語從句(1)原因狀語從句通常由because,since,as引導(dǎo)。because常回答why引導(dǎo)的疑問句，該從句一般位于主句后；since比as正式，兩者不回答why引導(dǎo)的問句，而且其從句一般放在句首。如：Hedidntcometoschoolbecausehewasill.Asitisraining,weshallnotgothezoo.Sinceyoucantanswerthequestion,Illasksomeoneelse.(2)because表示直接原因，語氣最強(qiáng)。because引導(dǎo)的原因狀語從句多放在主句之后?；卮鹩蓋hy提出的問題，只能用because。as和since語氣較弱，一般用來表示明顯的原因。由as和since引導(dǎo)的原因狀語從居多放在句首。例如：-Whyarentgoingthere?-BecauseIdontwantto.Ashehasnocar,hecantgetthereeasily.Sincewehavenomoney,wecantbuyit.(3)because和so不能同用在一個(gè)句子里。（4）for是并列連詞，引導(dǎo)的句子不置于句首，是一種非直接的、隨便附加說明的理由或推斷。Theoilmustbeout,forthelightwentout.（5）because和becouseof也有明顯的區(qū)別。because后面要跟從句，而becauseof后面要跟名詞短語。Heislateforschoolbecauseitrainsheavily.Heislateforschoolbecauseoftheheavyrain.,難點(diǎn)鏈接,6.目的狀語從句(1)目的狀語從句通常由sothat,inorderthat引導(dǎo)。例如：Westartedearlysothatwecouldcatchthefirsttrain.Hestudieshardsothathecouldworkbetterinthefuture.Weusedthecomputerinorderthatwemightsavetime.(2)sothat既可引導(dǎo)目的狀語從句，又可引導(dǎo)結(jié)果狀語從句。區(qū)別這兩種從句的辦法有兩個(gè)：1)目的狀語從句里往往帶有情態(tài)動(dòng)詞can,could,may,might等。2)從意思上看，目的狀語從句往往表示的目的很明確。例如：Speakclearlysothattheymayunderstandyou.（目的狀語從句）Jackisbadlyillsothathehastorest.(結(jié)果狀語從句),難點(diǎn)鏈接,(3）結(jié)果和目的狀語從句還要注意以幾點(diǎn)：sothat用在單數(shù)可數(shù)名詞前，so形容詞a名詞that，如：Sheissobeautifulagirlthateveryonelikesher或用sucha形容詞名詞that,如：Sheissuchabeautifulgirlthateveryonelikesher在不可數(shù)名詞或可數(shù)名詞復(fù)數(shù)前只能用such，如：Itissuchgoodweatherwewanttogoforapicnic又如：Theyaresuchgoodplayersthattheyshouldwinthegame.在much，many，few，little之前只能用so，如：IhavesolittlemoneythatIcantbuyitsothat之間只有形容詞時(shí)，則不能用such，如：ItissogoodthatIwanttobuysothat其后接從句，如：IgotupearliersothatIcouldcatchthefirstbus,難點(diǎn)鏈接,7.讓步狀語從句(1)讓步狀語從句通常由thoughalthough（雖然），eventhough（盡管），evenif(即使），whoever（無論誰），（無論怎樣），whatever（無論什么）等連詞引導(dǎo)。例如：Thoughheisyoung,heknowsalot.AlthoughIamtired,Imustgoonworking.Evenifheispoor,shelovesherhusband.(2)because不能與并列連詞so，thoughalthough不能與but同時(shí)在句中使用。如：Shewaslateforschoolbecauseshemissedthebus=Shemissedthebus，soshewaslateforschool我們不能說：Thoughitwasraininghard,buthestillwentout.應(yīng)該說：Thoughitwasraininghard,hestillwentout.或Itwasraininghard,buthestillwentout.,難點(diǎn)鏈接,8.方式狀語從句引導(dǎo)方式狀語從句的有as（按照）等。如：Iwilldoitasyoutellme我將照你說的做。方式狀語中要注意的是as(連詞)與like(介詞)的區(qū)別。as作為連詞其后接從句，如：PleasedoitasIdidit但后面的句子常作省略，如：PleasedoitasI而like是介詞，其后要接的是賓語，如：Pleasedoitlikeme9.地點(diǎn)狀語從句地點(diǎn)狀語從句常常由where來引導(dǎo)。例如：Gowhereyoulike.Wherethereisawill,thereisaway.,難點(diǎn)鏈接,1.誤Whiletheclockstruckten,allthelightswentout.正Whentheclockstruckten,allthelightswentout.析while是強(qiáng)調(diào)兩個(gè)動(dòng)作在同時(shí)進(jìn)行中，如：WhileIamdoingmyhomework,myfatherisreadinganewspaper.而這里的when是正當(dāng)某某時(shí)刻，就在這一時(shí)間點(diǎn)上，其重點(diǎn)強(qiáng)調(diào)在某一特定時(shí)刻某動(dòng)作的發(fā)生。2.誤WhileIwaswalkingalongthestreetyesterday,Imetanoldfriend.正WhenIwaswalkingalongthestreetyesterday,Imetanoldfriend.析這里用when表達(dá)在一個(gè)動(dòng)作的進(jìn)行中，另一個(gè)動(dòng)作突然發(fā)生了。正在進(jìn)行的動(dòng)作用一進(jìn)行時(shí)態(tài)，而突然發(fā)生的動(dòng)作用一般時(shí)態(tài)。3.誤WhileIheardthebadnewsIfeltsad.正WhenIheardthebadnews,Ifeltsad.析while不能表達(dá)一點(diǎn)兒的時(shí)間，即瞬時(shí)某一時(shí)間點(diǎn)。4.誤Forthereisnolightintheclassroom.Thestudentsmusthavegonehome.正Thestudentsmusthavegonehome,forthereisnolightintheclassroom.析由for引出的原因狀語從句在使用時(shí)要注意不能將該從句置于句首，而應(yīng)置于主句之后，并在主句與從句之間加一逗號。更要注意的是because,as,since與for4個(gè)表示原因的連詞中because是因果關(guān)系，是最強(qiáng)的一個(gè)，而for是最弱的一個(gè)。有些語法書中干脆把for叫做并列連詞,正誤辨析,5.誤Shesangwhenshewalkedalongthedarkstreet.正Shesangasshewalkedalongthedarkstreet.析as用于句中時(shí)，其要點(diǎn)是強(qiáng)調(diào)兩個(gè)動(dòng)作的同時(shí)進(jìn)行。這里用when雖然不能講是語法上的錯(cuò)誤，但則看不出來小女孩因獨(dú)自走黑暗的街道因害怕而唱歌的心情。6.誤Ifinishedmyhomeworkuntiltwelveoclocklastnight.正Ididntfinishedmyhomeworkuntiltwelveoclocklastnight.正Ididmyhomeworkuntiltwelveoclocklastnight.析until用在句中時(shí)其含義是某一動(dòng)作一直持續(xù)到某時(shí)結(jié)束，那么句中的動(dòng)詞則一定要用持續(xù)性動(dòng)詞，如果要用瞬間，或截止性動(dòng)詞時(shí)一定要用否定句式。因截止性動(dòng)作的否定式應(yīng)看作是持續(xù)性的動(dòng)作。如離開leave是瞬間動(dòng)作，因一出門即為離開了，而不離開則是長時(shí)間的。7.誤IhavestudiedEnglishwhenIwastwelve.正IhavestudiedEnglishsinceIwastwelve.析since引出的時(shí)間狀語從句是表達(dá)了一個(gè)時(shí)間點(diǎn)，而這個(gè)時(shí)間點(diǎn)是主句動(dòng)作的啟始點(diǎn)，所以主句一般要用完成時(shí)態(tài)。8.誤Becausehedidntstudyhard,sohedidntpasstheexam.正Hedidntpasstheexambecausehedidntstudyhard.析because與so在英文中兩者不能并用的，只能在句中用9.誤BeforeIdonotgiveyoutheanswer,Illaskyousomequestions.正BeforeIgiveyoutheanswer,Illaskyousomequestions.析這種錯(cuò)誤是由于受中文的影響。在中文中可以講我沒給你答案前。而英文用了before就不要再用否定句了。,正誤辨析,10.誤Hewassuchexcitedthathecouldnotspeak.正Hewassoexcitedthathecouldnotspeak.析so與such的用法可以分為四種情況，用于單數(shù)可數(shù)名詞之前，其格式是such+不定冠詞+形容詞+單數(shù)可數(shù)名詞，如：Itissuchabeautifulbookthateverychildlikesit.也可以用so,其格式是so+形容詞+不定冠詞+單數(shù)可數(shù)名詞，如：Itwassobeautifulabookthateverychildlikesit.在不可數(shù)名詞前或可數(shù)名詞復(fù)數(shù)前這時(shí)只能用such,如：Itissuchgoodweatherthatwewanttoswim.又如：Theyaresuchgoodstudentsthattheycanpasstheexameasily.在few,little，much,many這4個(gè)字前只能用so而不能用such,如：IhavesomuchmoneythatIcanbuyeverythingIwant.當(dāng)that前只有形容詞或副詞時(shí)，這時(shí)只能用so,如：Sheissobeautifulthateveryonelikesher.HeransofastthatIcouldntkeepupwithhim.11.誤Hegotupearlierthismorningsoastothathecouldcatchthefirstbus.正Hegotupearlierthismorninginordertotocatchthefirstbus.正Hegotupsoearlierthathecouldcatchthefirstbus.析sothat與sothat的用法有相同之處，那就是其后接從句，而inorderto其后要接不定式，即動(dòng)詞原形。12.誤Iwanttobuysamestampthatyouhave.正Iwanttobuythesamestampasyouhave.析thesameas(that)這是個(gè)固定用法，在same前的定冠詞是不能少的。而thesamethat意為我要的就是那一個(gè)。而thesameas為要的是和一樣的東西。,正誤辨析,根據(jù)A句完成B句，使兩句意思一致，每空只填一詞：1.A:Janeisasinger.Sheisalsoadancer.B:Janeis_asinger_adancer.2.A:Weshouldlearnfrombooksandweshouldlearnfromteachers.B:Weshouldlearn_frombooks_fromteachers.3.A:Hismothercanthelphimwithhislessons,andhisfathercant,either.B:_hismother_hisfathercanhelphimwithhislessons.4.A:Itshardwork,butIenjoyit.B:_itshardwork,Ienjoyit.5.A:Mencantlivewithoutairandwater.B:Menwilldiewithoutair_water.,課時(shí)訓(xùn)練,notonlybutalso,bothand,Neithernor,Though/although,or,6.A:Ifyoustandhigher,youwillseefarther.B:Standhigher,_youwillseefarther.7.A:Ifyoudontworkharder,youwillfailintheexam.B:Workharder,_youwontpasstheexam.8.A:Howimportantthemeetingis!Icantmissit.B:Itis_importantmeeting_Icantmissit.9.A:Afterthemothercameback,theboywenttobed.B:Theboy_gotobed_hismothercameback.10.A:Thereremanyrabbitsthere.Theycantkillthemall.B:Therere_manyrabbitsthere_theycantkillthemall.,課時(shí)訓(xùn)練,and,or,suchathat,didntuntil,sothat,11.A:WhenIgetthere,Illgotoseehimatonce.B:Illgotoseehim_Igetthere.12.A:Youmaystayathome.Youmayalsogooutwithus.B:Youmay_stayathome_gooutwithus.13.A:Maryisthetallestgirlinherclass.(福州)B:Maryis_anyothergirlinherclass.14.A:Peterdrawswell.Henrydrawswell,too.(廣西)B:Henrydraws_Peter.15.A:Maryrunsfasterthanmysister.(蘭州)B:Mysisterdoesntrun_Marydoes.,assoonas,eitheror,tallerthan,aswellas,asfastas,課時(shí)訓(xùn)練,16.A:UncleWangfinishedhiswork.Hewenthome.B:UncleWang_gohome_hefinishedhiswork.17.A:LucyhasbeenawayfromtheUSAfor5years.B:Its5years_she_theUSA.18.A:“Doesthegirlneedanyhelp?”heaskedme.B:Heaskedme_thegirl_somehelp.19.A:Mrs.Smithismyteacher.Sheisalsomygoodfriend.B:Mrs.Smithis_myteacher_mygoodfriend.20.A:“Nanjinghaschangedalottheseyears.”“Thatsright.”B:“Nanjinghaschangedalottheseyears.”“_it_.”,didntuntil,sinceleft,Ifneeded,notonlybutalso,So,has,課時(shí)訓(xùn)練,選擇填空1.Theydidntstartthework_theirteachercameback.A.untilB.whileC.assoonasD.if2.Thedictionarycostmetoomuch,_itsreallyuseful.A.andB.soC.butD.or3.Carl,areyouinterestedinswimming?-Yes,_Imnotgoodatitatall.A.soB.andC.orD.but4.Youllbelate_youdontgetupearlytomorrowmorning.A.ifB.whenC.beforeD.until5.Idliketochangethispairoftrousers,_givememymoneyback.A.soB.orC.butD.and,A,C,D,A,A,課時(shí)訓(xùn)練,6.Alicewantedtoknow_hergrandmotherlikedthebag.A.thatB.ifC.whichD.what7.Mr.Johnhasworkedinthatsmalltown_heleftCanadain1998.(山西)A.whenB.afterC.forD.since8.Thatwasourfirstlesson,_shedidntknowallournames.A.forB.butC.soD.or9._Saturday_SundayisOK.Illbefreeinthesetwodays.A.Either;orB.Neither;norC.Both;andD.One;theother10.Pleasecome_havedinnerwithus.A.andB.soC.butD.or,B,D,C,A,A,課時(shí)訓(xùn)練,11.Heislisteningtothemusic_heiswashingclothes.(廣西A.afterB.beforeC.thatD.while12._therearetoomanypeoplehere,_wehavetofindanotherhouse.A.Because;soB.Though;butC.Since;/D./;if13.LiLeisaid_hecouldfinishhishomeworkbeforesixoclock.A.ifB.whatC.thatD.when14.Canyoutellme_thenearesthospitalis?A.whatB.howC.whetherD.where15.ThisTVsetistoodear,_itgivesyouabetterpicture.A.orB.andC.ifD.though,D,C,C,D,D,課時(shí)訓(xùn)練,16.Dontdrinktoomuchteaintheevening,_youwontfallasleep.(大連)A.andB.soC.orD.but17._heisveryyoung,_heknowsseverallanguage(
