句型转换DE答题技巧\n句型转换是句子类别的转换。该题的目的在于检测学生运用各种句型的表达能力。要求学生对所学的句子结构和词形的变化做到概念清楚，运用准确。\n[例1]Thelittlegirlwassotiredthatshecouldn’tgofarther.Thelittlegirlwas______tired______gofarther.（一）句型转换的解题应试技巧1．必须弄清原句的句型和意思以及判别改写后的句子是什么句型。通过分析，我们不难发现，该题是由复合句转换为简单句，可用too…to句型。\n根据我们所学过的同义词组，lookaftersbwell相当于takegoodcareofsb.[例2]Ittookhimtwohourstodotheseexercisesyesterday.He______twohours______theseexercisesyesterday.该句的句型是Ittakessbsometimetodosth.英语表达该意思的还有spend…on句型。[例3]Imustlookaftermysisterwellathome.Imust________________________mysisterathome.\n很明显，这是两个简单句之间的转换，可用notstrongenough来填空。[例4]Theyweretired,sotheyhadarest.Theyhadarest______theyweretired.该句由并列句转换为复合句，可用because来连接，表示因果关系。[例5]Hewastooweaktocarrytheheavybox.Hewas__________________tocarrytheheavybox.\n从近年来的考题趋势来看，句型转换从单纯测试语法知识向改变句子结构填空，填词后使句意不变或与要求相符的方向发展。其中许多属于常用句型。可归纳如下：2．要熟悉常用句型的转换规律。\n[例3]Wecanflytothemoononeday.____________flytothemoononeday?(1)肯定句变为一般疑问句及否定句a.变为一般疑问句时，系动词be、助动词或情态动词置于主语之前。[例1]Hewassoclever.____________soclever?[例2]Johnfelthappyatthattime.______John______happyatthattime?WasheDidfeelCanyou\n[例3]Thedoctorcouldhelpthatpeople.Thedoctor__________thatpeople.b.变为否定句时，系动词、助动词或情态动词后加not。[例1]Thetwinswerehappytoseetheiruncle.Thetwins____________toseetheiruncle.[例2]Mr.Smithworkshardeveryday.Mr.Smith____________hardeveryday.weren’thappydoesn’tworkcouldn’thelp\n[例2]IcoulddanceandsingwhenIwasfive　yearsold.I______dance______singwhenIwas　fiveyearsold.如果肯定句中含有some，and，alotof\lotsof，already，too\also,both…and,everything\everyone\everybody,always等词(组)，要变为any，or，much\many，yet，either,neither…nor,nothing\nobody,never。c.注意：[例1]TheyhadlotsoffriendsinChina.They_____have______friendsinChina.didn’tmanycouldn’tor\n[例]Hecanmakeamodelplane,Ithink.(否定句)I______thinkhe______makeamodelplane.[例1]Mothertoldmetogotobedearlylastnight.Mothertoldme____________gotobedearlylastnight.d.否定前移e.一些特殊结构，变否定句时，在动词（词组）后直接加not。don’tcannotto\n另外，还有asksb(not)todosth，Willyouplease(not)dosth，hadbetter(not)dosth，try(not)todosth,decide(not)todosth等。[例2]Let’splaybasketballontheplaygroundthisafternoon.Let’s____________basketballontheplayground.notplay\n[例2]Themaninthecarismyfather’sfriend.____________is______father’sfriend?(2)对划线部分提问对划线部分提问是根据划线的内容提出一个特殊疑问句。即特殊疑问词+一般疑问句构成。a.如划线部分是定语，它所修饰的词要跟随特殊疑问词移至句前。[例1]ThisisKate’shat.____________isthis?WhosehatWhichmanyour\n[例2]AnnflewtoBeijinglastyear.What_____Ann______lastyear?b.划线部分如是谓语动词，应该用do的形式来取代。[例1]Theyarelookingfortheboyinthecity.______arethey______inthecity?Whatdoingdiddo\nc.常见疑问词(组)：what，what+名词(如whatcolour，whatgrade等)，when，why，where，who(whom)，which，whose，how，how+形容词\副词(如howlong，howfar，howoften，howsoon等)。要注意以上各种疑问词(组)的用法。\nd.注意一些特殊词，如little、few、no、nothing、never等出现时，前半句表示否定的概念，后半句应用肯定形式。(3)改为反意疑问句反意疑问句的前半句为陈述句，后半句为简短的一般疑问句，在改写当中，要注意：a.前肯后否，前否后肯；b.人称、时态和数要保持一致；c.各种祈使句，反意疑问句的后半句都用willyou，但Let’s…句用shallwe；\n[例4]Don’ttellhimthebadnews,____________?[例1]Class3werethewinnersintherace,____________?[例2]Themancouldn’tclimbupthetree,____________?[例3]Thereislittlewaterinthebottle,____________?weren’ttheycouldheistherewillyou\n另外，注意以下句子：Iamastudent,____________?Whatakindgirl,____________?Howfasttheboyruns,____________?aren’tIisn’tshedoesn’the\n[例3]Idon’tknowwhatIcando.Idon’tknow____________do.(4)复合句变为简单句由复合句变为简单句时，一般都是将复合句中的从句改为不定式形式，或是介词短语的形式。比如so…that可以改写成too…to结构的简单句，但应注意to后面必须直接跟行为动词的原形。[例1]Hewassoyoungthathecan’tread.Hewas__________________read.[例2]Wecan’tliveifthereisnoairorwater.Wecan’tlive______airorwater.tooyoungtowithoutwhatto\n[例2]LiLeiisthetallestinhisclass.LiLeiis______than____________studentinhisclass.(5)特定词组、句型的特殊用法[例1]What’sthematter,Granny?____________withyou,Granny?What’swrongtalleranyother\n[例3]Youcan’ttakeboththebasketballandthefootball.Youcantake______thebasketball______thefootball.(6)同义句转换[例1]LiPingdoeswellinEnglish.LiPing_______________English.[例2]Icanmendthebike.LiLeican,too.Icanmendthebike,and__________LiLei.isgoodatsocaneitheror\n[例2]Hisbrotherwon’tdotheshoppingtomorrow.(改为一般现在时)Hisbrother__________theshoppingonSundays.(7)时态转换[例1]Wearegoingtohelpthefarmersonthefarmtomorrow.(用now改写)We____________thefarmersonthefarm______.arehelpingnowdoesn’tdo\n[例3]Theflowersarebeautiful.__________________theyare!__________________flowersare!（8）改为感叹句[例1]ThetwinsstudyChineseveryhard.__________thetwinsstudyChinese![例2]Theweatherwasratherbadyesterday.__________________itwasyesterday!HowhardWhatbadweatherWhatbeautifulflowersHowbeautifulthe\n3．反复推敲，确保无误。改变后要看看意思是否与要求相符，有没有语法和习惯用法方面的错误。（二）做句型转换时应注意的几个问题首先应看清题意，分析句子结构，再按句子要求变换句型。1．注意时态；2．句子的成分不变。原句的句子在改变句型时仍不可缺少，否则句子不完整，但有一个例外，在陈述句改为感叹句时，要增加句子成分，感叹词what和how分别为按句子的要求而增加的定语或状语，句子其他成分不变；练习题（略）\nThankyouforyourcoming！Goodbye!
