中考英语句型转换,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。,例1The little girl was so tired that she couldnt go farther.The little girl was _ tired _ go farther.,（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tooto句型。,根据我们所学过的同义词组，look after sb well相当于take good care of sb.,例2 It took him two hours to do these exercises yesterday.He _ two hours _ these exercises yesterday.,该句的句型是It takes sb sometime to do sth.英语表达该意思的还有spendon句型。,例3 I must look after my sister well at home.I must _ _ _ _ my sister at home.,很明显，这是两个简单句之间的转换，可用not strong enough来填空。,例4They were tired,so they had a rest.They had a rest _ they were tired.,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5He was too weak to carry the heavy box.He was _ _ _ to carry the heavy box.,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。,例3We can fly to the moon one day._ _ fly to the moon one day?,(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 He was so clever._ _ so clever?,例2John felt happy at that time._ John _ happy at that time?,Was,he,Did,feel,Can,you,例3 The doctor could help that people.The doctor _ _ that people.,b.变为否定句时，系动词、助动词或情态动词后加not。,例1 The twins were happy to see their uncle.The twins _ _ to see their uncle.,例2 Mr.Smith works hard every day.Mr.Smith _ _ hard every day.,werent,happy,doesnt,work,couldnt,help,例2I could dance and sing when I was five years old.I _ dance _ sing when I was five years old.,如果肯定句中含有some，and，a lot oflots of，already，tooalso,bothand,everythingeveryoneeverybody,always等词(组)，要变为any，or，muchmany，yet，either,neithernor,nothingnobody,never。,c.注意：,例1They had lots of friends in China.They _ have _ friends in China.,didnt,many,couldnt,or,例 He can make a model plane,I think.(否定句)I _ think he _ make a model plane.,例1Mother told me to go to bed early last night.Mother told me _ _ go to bed early last night.,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。,dont,can,not,to,另外，还有ask sb(not)to do sth，Will you please(not)do sth，had better(not)do sth，try(not)to do sth,decide(not)to do sth等。,例2 Lets play basketball on the playground this afternoon.Lets _ _ basketball on the playground.,not,play,例2 The man in the car is my fathers friend._ _ is _ fathers friend?,(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 This is Kates hat._ _ is this?,Whose,hat,Which,man,your,例2 Ann flew to Beijing last year.What _ Ann _ last year?,b.划线部分如是谓语动词，应该用do的形式来取代。,例1 They are looking for the boy in the city._ are they _ in the city?,What,doing,did,do,c.常见疑问词(组)：what，what+名词(如what colour，what grade等)，when，why，where，who(whom)，which，whose，how，how+形容词副词(如how long，how far，how often，how soon等)。要注意以上各种疑问词(组)的用法。,dd.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will you，但Lets句用shall we；,例4 Dont tell him the bad news,_ _?,例1 Class 3 were the winners in the race,_ _?,例2 The man couldnt climb up the tree,_ _?,例3 There is little water in the bottle,_ _?,werent,they,could,he,is,there,will,you,另外，注意以下句子：I am a student,_ _?What a kind girl,_ _?How fast the boy runs,_ _?,arent,I,isnt,she,doesnt,he,例3I dont know what I can do.I dont know _ _ 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sothat可以改写成tooto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 He was so young that he cant read.He was _ _ _ read.,例2 We cant live if there is no air or water.We cant live _ air or water.,too,young,to,without,what,to,例2 Li Lei is the tallest in his class.Li Lei is _ than _ _ student in his class.,(5)特定词组、句型的特殊用法,例1 Whats the matter,Granny?_ _ with you,Granny?,Whats,wrong,taller,any,other,例3 You cant take both the basketball and the football.You can take _ the basketball _ the football.,(6)同义句转换,例1 Li Ping does well in English.Li Ping _ _ _ English.,例2 I can mend the bike.Li Lei can,too.I can mend the bike,and _ _ Li Lei.,is,good,at,so,can,either,or,例2 His brother wont do the shopping tomorrow.(改为一般现在时)His brother _ _ the shopping on Sundays.,(7)时态转换,例1 We are going to help the farmers on the farm tomorrow.(用now改写)We _ _ the farmers on the farm _.,are,helping,now,doesnt,do,例3The flowers are beautiful._ _ _ they are!_ _ _ flowers are!,（8）改为感叹句,例1 The twins study Chinese very hard._ _ the twins study Chinese!,例2The weather was rather bad yesterday._ _ _ it was yesterday!,How,hard,What,bad,weather,What,beautiful,flowers,How,beautiful,the,3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；,英语格言ENGLISH
