冀教版七年级英语——句型之间转换的规则一、肯定句转换为否定句的规则：1.首先看句子中是否有情态动词can,may,must,could,should,would或will等词中的任何一个。
如果有，则在该词后面加上not，句子其余部分都不变，原肯定句就变成了否定句。
例：（1）I can swim.→否定句：I can not swim.（2）We will go to Beijing tomorrow.→否定句：We will not go to Beijing tomorrow.或We won’t go to Beijing tomorrow.2.其次，如果句中无上述情态动词，则看句中是否有be动词的各种形式如is,am,are 或was,were中的任何一个。
如果有，则在该词后面加上not，句子其余部分都不变，原肯定句就变成了否定句。
例：（1）This is my book.→否定句：This is not my book.（2）They are pandas.→否定句：They are not pandas.3.如果句子中没有如上述1、2所列的动词，则先找出句中的动词。
（1）如果句中动词为原形，则在该动词前面加don’t，句子其余部分都不变，原肯定句就变成了否定句。
例：We like English.→否定句：We don’t like English.（2）如果句中动词为第三人称单数形式，则在该动词前面加doesn’t，之后动词变为原形，句子其余部分都不变，原肯定句就变成了否定句。
例：He likes English.→否定句：He doesn’t like English.（3）如果句中动词为过去式，则在该动词前面加didn’t，之后动词变为原形，句子其余部分都不变，原肯定句就变成了否定句。
例：We liked English.→否定句：We didn’t like English.二、肯定句转换为一般疑问句的规则：1.首先看句子中是否有情态动词can,may,must,could,should，would或will等词中的任何一个。
英语句型转换之【2 】二——确定句变一般疑问句的办法A. 请同窗们记住以下单词：1.be动词的五种情势：am, is, are, was, were;2.情态动词：can, could, may, might, must, shall, should,will,would, need, had better3.助动词：have, has, hadB. 一般疑问句根本构造为：Be动词或助动词或情态动词 + 主语 + 谓语 + 动词 + 其他?C. 变一般疑问句的口诀有二：1. 一调二改三问号;2. 一找二改三问号.D. 具体办法如下：一.be动词,情态动词和助动词直接调到主语前原句中含有be动词(am, is, are, was, were) 和情态动词(can, shall, will, may, should, would, might, had better等)时,把他们直接调到主语前.如：He teaches English.---- Does he teach English?1. He is a teacher.→Is he a teacher?2. Li Lei can speak English. →Can Li Lei speak English?3. They will go to the aquarium if it is fine tomorrow.→Will they go to the aquarium if it is fine tomorrow.4. There were many students in the classroom.→Were there many students in the classroom?二.原句中没有be动词.助动词或情态动词时,要依据下面不同情形在主语前加助动词do, does, did.1. 句中第一个动词是本相时,在主语前加上do.如：I get to school at six o'clock every day.→Do you get to school at six o'clock every day?2. 句中第一个动词是三单情势时,在主语前加上does,本来的动词三单情势改为动词本相.如：He teaches English.→Does he teach English?3. 句中第一个动词是曩昔式时,在主语前加上did,本来的动词曩昔式改为动词本相.如：The children had a good time in the park last night.→Did the children have a good time in the park last night?三.确定句变一般疑问句的几点留意1. 确定句变一般疑问句时,除上述变化外,句中其他词语也可能随之转变,如将some改为any,something改为anything, my改为your, I改为you,already.still改为yet等.如：There are some apples in the tree..→Are there any birds in the tree?The dentisthas already seen the moive.→Has the dentist seen the moive yet?2. 须要分清do, does, did, have, has, have, had等是实义动词照样助动词.假如是助动词,则把它们直接调到主语前,假如是实义动词,则在主语前面依据现实情形加do, does或did.如：Mary usually does some readingon Saturdays.→Does Mary usually any readingon Saturdays?（Wrong）→Does Mary usually do any readingon Saturdays?（Right）I have taught English here for two years→Do you have taught English here for two years?（Wrong）→Have you taught English here for two years?（Right）演习题一.填空,把下面的句子变成一般疑问句：1.

英语句型之肯定句变一般疑问句情况一：1：寻找以下单词。
