状语从句(有答案).doc

Unit3CouldyoupleasecleanyourroomCouldyouplease.?句型（1） 请求别人时通常用此句型，也可以说：Canyou.please?情态动词could或can在这里均表示请求，在意思上无区别，但是用could在于其上显得更委婉、客气、诚恳。在日常生活中常使用couldyou/I.?若在句末加上please，则显得更礼貌。Couldyouhelpmefindmybook,please?你能帮我找到我的书吗？（2） 对couldyou/I.?的问句作出肯定回答，常用“sure/certainly/ofcourse”等；如果作否定回答，常用“sorry或oh,pleasedont”。一般不用no开头，用no显得语气生硬、不礼貌。（3）表示请求的句式：Wouldyouliketodo.?Wouldyouminddoing.?Letsdo.ShallI/wedo.?Pleasedo.(祈使句前加please)提示：couldyouplease.与couldIPlease.两种问句，前者是请求别人帮忙的句式，后者是有礼貌地向别人请求允许的交际用语。试比较：Couldyoupleasehelpme?请你帮我一下好吗？CouldIpleaseinvitemyfriendstomybirthdayparty,Mom?妈妈，我能邀请我的朋友参加我的生日聚会吗？状语从句（二）、条件状语从句1. If引导：连词，意为“假如，如果”。当主句是将来时的时候，从句要用一般现在时。 Donttalkloudlyatthemeeting.Ifyoudo,youwillhavetoleave.Wellgoforapicnicifitdoesntrainthisweekend.2. unless引导：连词，意为“除非（=ifnot）。当主句是将来时的时候，从句要用一般现在时。 Dontdiscusstheproblemswithyourpartnerunlessyouareaskedtodoso.Iwontgothereunlessyoucomewithme.Ill go unless it rains.Ill go if it doesnt rain.（三） 、原因状语从句1. Because：意为“因为”。引导的原因状语从句一般放于主句之后，表述直接原因，语气较强，最适合why引导的疑问句。Because引导的原因状语从句有时可以与becauseof短语互换。Idliketocollectstampsbecausetheyareinteresting.Imverytiredthesedaysbecauseofstudyingmath.Hecantcomebecauseheisill.=Hecantcomebecauseofhisillness. 2. Since:意为“因为”。引导的原因状语从句一般放于主句之前表示已知的、显然的理由（通常被翻译成“既然”），较为正式，语气比because弱。SincetheraceisinApril,Ihadtorunthroughoutthewinter.Sinceeverybodyishere.Letsbeginourmeeting.3. As：意为“因为”。引导原因状语从句时表示附带。说明“双方已知的原因”，语气比since弱，较为正式，位置较为灵活（常放于主句之前） Astheweatheriscold,Istayathome. Asyouaretired,youdbetterrest.4. For:意为“因为”。引导的原因状语从句并不说明主句行为发生的直接原因，只提供一些辅助性的补充说明。 Hecouldnothaveseenme,forIwasnotthere.（四） 、目的状语从句1. So that: 意为“以至，以便”。目的状语的谓语常含有may,might,can,could,should,would等情态动词。Trytospeakloudenoughsothatpeoplecanhearyouclearly.Mr.Greenspeaksveryloudlysothatallthepeoplecanhearhimclearly.2. In order that: 意为“为了”，相当于sothat.inorderto后面可以跟动词原形构成目的状语，不是目的状语从句。Weshallletyouknowthedetailssooninorderthatyoucan/maymakeaarrangements.3. In case: 意为“以防”Take an umbrella with you in case it rains. （五） 、结果状语从句1. So that: 意为“如此以至于”。 Jim did well in exam so that he was praised by his teachers.2. so+adj./adv.原级+that,so是副词，只能修饰形容词和副词。 ThisyearithasrainedsoheavilyinSouthChinathatlotsofproblemsarecaused.3. so还可与表示数量的形容词many,few,much,little(这四个形容词表示多或少时)连用,形成固定搭配。so+many或few+复数可数名词+that;so+much或little+不可数名词+that.Wespendsomuchtimethinkingaboutthefuturethatwefailtoenjoythe present.TherearesofewnotebooksthatIcantgiveyouany.4. Such.that: 意为“如此以至于”。常用结构such+a(an)+adj.+单数可数名词+that;such(+adj.)+不可数名词+that;Itssuchawonderfulsongthatwealllikeit.It is such fine weather that id like go to park.Theboyissoyoungthathecantgotoschool.=Heissuchayoungboythathecantgotoschool.（六） 、让步状语从句1. Though:意为“虽然”。不能和but连用。但是可以同yet(still)连用构成thoughyet(still).even能和though组合表示强调，在这里eventhough=evenif(nomatterif; Thoughtheyaretwinbrothers,theydontlooklikeeachother. Evenif/Eventhoughwecouldaffordit,wewouldntaffordit.2. Although: 意为“虽然”。不能和but连用，但是可以同yet(still)连用，构成althoughyet(still).although较为正式，语气比though重，常用以强调让步概念。even不能和although组合。 Althoughhediedseveralyearsago,Icanstillrememberthedayswespenttogether.练习一一.单项填空1. _A_hesold,hecanstillcarrythisheavybag.A.ThoughB.SinceC.ForD.So2.-Doyouknowifhe_C_toplaybasketballwithus?-Ithinkhewillcomeifhe_freetomorrow.A.comes;isB.comes;willbeC.willcome;isD.willcome;willbe3.Inthezooifachild_B_intothewaterandcantswim,thedolphinsmaycomeup_him.A.willfall;tohelpB.falls;tohelpC.willfall;helpD.falls;helping5.Wewillstayathomeifmyaunt_A_tovisitustomorrow.A.comesB.comeC.willcomeD.iscoming6.Thepoliceaskedthechildren_C_crossthestreet_thetrafficlightsturnedgreen.A.not;beforeB.dont;whenC.notto;untilD.not;after7.Iwaslateforclassyesterday_D_therewassomethingwrongwithmybike.A.whenB.thatC.untilD.because8.
