上海中考英语句型转换讲解与练习

上海中考英语句型转换讲解与练习考点讲解一、肯定句改为否定句在做此类题时,通常在系动词、助动词和情态动词后加not n't;如果句中没有这些词,则根据谓语动词的原形、第三人称单数动词形式或过去式而分别在其前面加do not don't, does not doesn't 或did not didn't, 并将第三人称单数动词形式或过去式改为原形;如：We can finish the work this afternoon. →We can't finish the work this afternoon.They put the basket under the tree just now. →They didn't put the basket under the tree just now.注意：1. 当think, believe, suppose等动词后面跟宾语从句时,通常用否定主句谓语动词来达到否定从句谓语动词的目的;如：I think they can come tonight. →I don't think they can come tonight. 2. 当must表示推测,表示“一定；肯定”的含义时,否定句应用can't;如：He must be in the room. →He can't be in the room.二、陈述句改为疑问句陈述句改为疑问句一般有三种情况：一是改为一般疑问句,二是改为反意疑问句;如:1. The students had learned about 1,000 English words by the end of last term. 改为一般疑问句→Had the students learned about 1,000 English words by the end of last term 2. The twins have never been to the Summer Palace, have they 完成反意疑问句三、对划线部分提问对划线部分提问,就是用一个合适的疑问词去替代句中的某一成分,使之成为一个特殊疑问句;当对主语或主语的定语提问时,用陈述句语序;对定语提问时,所修饰的名词应放在疑问词后;对其他成分提问,用“疑问词+一般疑问句语序”;如：1.Tom will be back in ten days. 对划线部分提问→Who will be back in tendays2. He writes to his father once a month. 对划线部分提问→How oftendoes he write to his father四、同义句改写1．根据句意改写主要考查学生对句意的理解和用一个词或一种结构来概括上句的意思的综合能力;如：1.

英语句型转换必备

英语句型转换必备一、中考知识点梳理：提纲挈领，抓住重点和难点句型转换是要求学生根据所给的句型，按要求或提示完成考题，考查的是学生对句子结构的构成、变化等方面的知识以及对此类知识的运用能力。

该题型首先给出一个完整的句子，再给出一个含有几个空白处的句子，根据不同的要求填入适当的词完成句型转换。

句型转换涉及到语法知识的各个方面，在做这种题时，应注意时态、语态、人称、数的变化，特殊疑问词的用法，及助动词的用法等。

句型转换考题虽然包括各种句式，但通常以两种形式进行考查：同义型句型转换和条件型句型转换。

一、同义型句型转换同义型句型转换即是用另一种方式来表述与原句相同的句意，也称作同义句转换，主要考查学生对句型及词汇的掌握情况。

二、条件型句型转换条件型句型转换即是要求根据句子后给出的具体要求变换句型。

具体考查内容为：1.单数句、复数句之间的转换；2.肯定句、否定句、疑问句之间的转换；3.简单句、并列句、复合句之间的转换；4.陈述句、感叹句、祈使句之间的转换；5.主动语态、被动语态之间的转换。

二、典例精析：举一反三，学的更轻松！1.I prefer walking there to going by bus.I prefer to walk there ___ by bus.【解析】该题考查prefer...to...与prefer...rather than...这两个句型的转换。

前者后接动词时用V.+ing形式，而后者则接不定式，并且rather than后的不定式符号要省略。

答案：rather than go。

2.It took Mary two weeks to prepare for the exam.Mary ____ two weeks ___ for the exam.【解析】该题考查的是表示“花费时间做某事”的两个句型的转换，take常用的句型是：it takes +时间+ to do...；而spend却是：sb. +spend + 时间+ （in）doing...。

中考英语句型转换典型例题及详解

中考英语句型转换典型例题及详解模块十六：句型转换一、题型分析句型转换是目前英语中考的一个常见题型，主要考查学生对不同句子结构（语法）的语言运用能力。

句子结构和词汇同样是英语学习的基础。

英语和汉语属两种不同的语言。

句子结构自然有很大的不同。

不同句子的结构掌握的越多，英语语言运用的能力就越强。

如果你不能用不同的句子结构表达同一意思，你才能有运用自如的感觉。

所以要学好英语。

必须熟练掌握各类英语句子的基本结构和句型。

同时，更多地掌握英语的句法还能提高阅读，写话，以至于听力等能力。

英语中考考查句子结构题型是“按要求改写句子”。

学生只要掌握英语句子的基本结构和单词拼写，该大题得满分并不难的。

二、解题技巧1、掌握英语的基本句子形式，如陈述句，各种形式的否定句，一般疑问句，特殊疑问句，反意疑问句，感叹句。

主动语态和被动语态结构等。

请看下面的例句和分析。

1.He has lunch at school. (改为否定句)He lunch at school.本句动词have 不表示“有”而是表示动作，应用doesn’t have,不能用has not.2.The T-shirt cost five dollars.(改为一般疑问句)the T-shirt five dollars?该句的cost 是过去式，不需要加s。

本句应用Did, cost.英语有几个动词过去式和现在式同一形式，set,cut,put,let,fit,read,spread等，要看清楚再做。

3.The photo near the door is the best.(就划线部分提问)is the best?本句用Which photo,因为near the door 用作定语修饰名词photo,别认为near the door 是地点而用错where。

4.We have studied in this school for four years,(改为特殊疑问句)have you studied in this school?本句虽没有划线部分，但根据句子其他部分意思，可以看出是对for four years 进行提问，肯定用How long.5. Let’s go to the exhibition this afternoon.（改为反义疑问句）Let’s go to the exhibition this afternoon，？6.He could hardly see the words on the blackboard. （改为反义疑问句）He could hardly see the words on the blackboard, ?祈使句的反义疑问句，仅Let’s…句型用shall we，其他都用will you. 而一般疑问句改反义疑问句应注意，若句子的主要部分用肯定，附加部分用否定，反之则相反。

中考英语句型转换的方法

句型转换方法归纳一．改为一般疑问句1、先找be动词 am, is, are, was, were或情态动词can, may ,must, would，should ,could .如果有这些词，直接把这些词放在句子最前面， some 改成any，句号改成问号?其余照抄；（如果主语是第一人称I/we，my/our则变成第二人称you, your）例如：They are in the park. Are they in the park? He can play the guitar. Can he play the guitar?1. I am listening to music.2. Mike is a student.3. Sarah can clean the classroom.4. They are in the zoo.5. There are some flowers in the vase.6. This is my sister.7. We are sweeping the floor.2、如果句子中没有be动词或者是情态动词，要在句子最前面加助动词 do 、does或者是did:1.判断句子时态，如果句子是过去式，则要在句最前面加Did，后面动词用原型，some改成any，句号改成问号，其余照抄；（如果主语是第一人称则变成第二人称）2.如果句子不是过去式，则判断是否为第三人称单数(it, she, he, a desk, this cup, his brother等)，如果第三人称单数，要在句子最前面前加助动词Does,后面动词用原型，some 改成any，句号改成问号，其余部分照抄。

（如果主语是第一人称则变成第二人称）3.其他情况均要在句子最前面加助动词do，some改成any，句号改成问号，其它部分照抄. （如果主语是第一人称则变成第二人称）例如：I like the ducks. Do you like the ducks? He likes the dogs.Does he like the dogs?1.We need some masks.2.They like making the puppet.3.Su Hai and Su Yang live in a new house.4．.I put a book on my head.5. They sing in the classroom together.6.We play basketball on Sundays.7. Tom likes listening to music.改为一般疑问句总结：一、把be动词（am is are）和情态动词(can, may, must...)放到句首，其它照写。

在历年的中考中，对话题所占的分值一直挺大，而且有愈来愈高之势，能行而有效的为中考对话题打下坚实的基础。

Ⅱ.题型分类从形式上看，有如下几种形式：①某一词或词组的转换；②词组与句子的转换；③同义句型的转换；④为纠正常犯语言错误而设计的题目。

从内容上看，此题型涉及的面较广，主要有：①句子功能方面的转换。

包括陈述句（肯定与否定）、四种题疑问句、祈使句、感叹句的转换；②句子结构方面的转换。

即简单句、复合句、并列句之间的转换；③语态的转换。

即主动语态与被动语态之间的转换；④常用句型与词汇手段的转换。

Ⅲ.具体分类如下一、由肯定句变为一般疑问句由肯定句变为一般疑问句的规则是把句子变为疑问语序，也称之为倒装语序。

解题时应把握以下几点：A. be动词、情态动词、助动词直接提前B. 有实义动词v时，请助动词do/does(请助动词三步口诀：看人称、请助动词、动词还原形)1、句子的谓语动词如果是be动词，则把be动词直接提到主语之前。

（注：在肯定句和一般疑问句中主语的一、二人称要互换。

）eg. (1) We are in Class 1, Grade 7 .→ Are you in Class 1, Grade 7 ?(2) He's polite and helpful .→ Is he polite and helpful ?(3) There are some birds in the big tall tree .→ Are there any birds in the big tall tree ?(4) Some Americans are going to visit our school next week .→ Are some Americans going to visit your school next week ?(5) A new modern bridge is being built over the Changjiang River .→ Is a new modern bridge being built over the Changjiang River ?2、句子的谓语动词中如果有情态动词，则把情态动词直接提到主语之前。

eg. (1) They can park their cars in front of the supermarket .→ Can they park their cars in front of the supermarket ?(2) I'd like some more dumplings .→ Would you like some more dumplings ?(3) Children must be kept away from fire .→ Must children be kept away from fire ?3、句子的谓语动词如果是现在完成时或过去完成时，则把时态中的助动词have、has或had提到主语之前即可。

eg. (1) I have finished reading the interesting book .→Have you finished reading the interesting book ?(2) The old woman had been dead before her daughter arrived .→ Had the old woman been dead before her daughter arrived ?4、句子的谓语动词如果是行为动词的一般现在时或一般过去时，在改为一般疑问句的时候，根据主语的人称和单、复数，需要添加助动词do、does或did 。

eg. (1) We enjoy the football matches very much .→ Do you enjoy the football matches very much ?(2) Her mother does some cleaning every morning .→Does her mother do some cleaning every morning ?(3)She went to see her doctor yesterday .→Did she go to see her doctor yesterday ?注：在添加了助动词的一般疑问句中，行为动词一律为动词原形。

二、由肯定句变为否定句由肯定句变为否定句的规则是在句中的助动词之后添加否定词not。

1、be动词、情态动词、助动词直接+not(除了be动词的am词形外，否定词not可以和助动词缩写为“助动词+ n't”。

)2、有实义动词v时，请助动词do/does+not(请助动词三步口诀：看人称、请助动词、动词还原形)分别可以缩写为don't、doesn't和didn't 。

注：在行为动词一般现在时和一般过去时的否定句中，行为动词也一律为动词原形。

eg. (1) He is from England .→He isn't from England .(2) They can look for things on the Internet in Computer lessons .→They can't look for things on the Internet in Computer lessons .(3) I have seen the interesting film already .→I haven't seen the interesting film yet .(4) His brother often plays football after school .→His brother doesn't often play football after school .(5) My grandma came for dinner yesterday evening .→My grandma didn't come for dinner yesterday evening .下面几种句型在变为否定句时情况特殊一些，做题时须引起注意：(1) I think + 宾语从句。

该句型在变为否定句时，否定词not应放在主句上，即为：I don't think + 宾语从句。

eg. I think it will rain tomorrow .→ I don't think it will rain tomorrow .(2) 祈使句祈使句的特征是没有主语，以动词原形开头。

祈使句在变为否定句时，应在动词原形之前添加助动词don't .eg. (1) Water the flowers .→ Don't water the flowers .(2) Please clean the blackboard .→ Please don't clean the blackboard .三、句子的单复数互换句子的单复数转换的规则是：对应句中的名词、代词、动词等，能变则变，不能变的，要么保留，要么去掉。

在解题过程中，还必须具体情况具体对待。

eg. (1) The girl is from England .→ The girls are from England .(2) He is a polite and helpful boy .→ They are polite and helpful boys .上述例句中，划线的为能变的，没划线的为该保留的，a(an)为该去掉的。

反之，在由复数变为单数时，则要根据句意在名词之前补上一个a(an)。

eg. They are English girls . → She is an English .但是对于"There be"句型，单复数转换时句中的 a / an不能去掉，而要根据句式将其与some或any 互换。

eg. (1) There is a boat on the lake .→ There are some boats on the lake .(2) There isn't a tree behind the house .→ There aren't any trees behind the house .(3) Is there a pet dog in your home ?→ Are there any pet dogs in your home ?(4) There aren't any pictures on the wall of our classroom .→ There isn't a picture on the wall of our classroom .四、同义句转换同义句转换就是将所给的句子换个说法。

这一题型包含的内容多，形式杂。

有词汇的同义转换，句型的同义转换等。

掌握该题型的解题技巧，可以很好地帮助学生理解、掌握所学的词汇和句型的含义，并在此基础上加以活用，对学生形成语言综合运用能力有极大的帮助。

要掌握该题型的正确的解题方法，需要在日常的英语学习中不断练习、归纳、积累。

一般说来，同义句转换主要有以下几种形式：1、词汇的同义转换词汇的同义转换主要有同义词、近义词的转换,反义词的转换,和同一个词在不同的句式中的不同的语序的转换等。

eg. (1) I spent 50 yuan on the coat .→I paid 50 yuan for the coat .（同义词的转换）(2) He likes playing football too .→ He also likes playing football .（近义词的转换）(3) Millie sits behind Daniel .→ Daniel sits in front of Millie .（反义词的转换）(4) They are all from America .→ All of them are from America .（词序的转换）2、句型的同义转换常见的句型的同义转换主要有以下几种形式：A.简单句和简单句的互换，B.简单句和祈使句的互换，C.复合句和简单句的互换，D.复合句和复合句的互换等。
