陈述句变一般疑问句和肯定句变否定句的几点技巧

陈述句变一般疑问句1、首先看句子当中有没有be动词（am/is/are）或情态动词（can/will/would/should），如果有，则把他们提到句首；2、如果没有，则在句首加Do或Does（第三人称单数开头的一般现在时的句子用Does，并注意把谓语动词变为原形），3、一般疑问句的回答，肯定回答：Yes，主语代词+句首词.否定回答：No，主语代词+句首词与not的缩写形式。

2、四点注意：1、注意人称变化，2、注意大小写变化，3、注意标点符号的变化，4、注意把some变成any（would like句型除外）。

例：This is my pen.is 提到了句首第一人称变为第二人称，句号变为问号？一般疑问句：Is this your pen?肯定回答：Yes，this is. No，this isn’t.句首词主语代词句首词句首词和not的缩写例：Xiaoming goes to school by bike.分析：首先，句子当中没有be动词和情态动词，所以只能用Do或Does,因为主语Xiaoming 为第三人称单数，所以用Does，那么变为一般疑问句：Does Xiaoming go to schoo by bike? 肯定回答：Yes，he does. No，he doesn’t.句首词主语代词句首词句首词和not的缩写肯定句变否定句：首先看句子当中有没有be动词（am/is/are）或情态动词（can/will/would/should），如果有，则在他们后面加not；2、如果没有，则在主语后加Don”t或者Doesn’t（第三人称单数开头的一般现在时的句子用Doesn’t，并注意把谓语动词变为原形）对划线部分提问：1、首先看划线部分，根据划线部分的汉语意思判断特殊疑问词，并将特殊疑问词写在句首；2、然后把划线部分外的内容，变为一般疑问句，并写在特殊疑问词的后面。

3、注意：询问职业的用What do/does 人do? 或者What is/are 人称所有格job?询问爱好的用What is/are 人称所有格hobby/hobbies?询问动作时，注意加do特殊疑问词：What 对动作、事物提问Who 对人提问Where 对地点提问When 对时间提问How 对身体状态、出行方式提问Whoes 对某人的。

句型转换的方法一、肯定句改否定句的方法——一步法1、在be动词后加not;如：is not , are not , am not, was not, were not；2、在can,should, will等后加not;如：cannot, should not, will not；3、上述都没有的,在动词前加助动词否定形式don’t/doesn’t/didn’t;4、 some 改成any;把下面的句子变成否定句;1.She is watching TV now.2.We go to school on Sunday.3.His father works hard.4.Jack's mother is a nurse.5.The cat runs fast.6.They like reading books.7.My grandpa gives me a hot dog.8.Tom often walks to school.9.I have a doll.It is eating fish.二、肯定句改一般疑问句的方法——三步法1、把be动词放在句首,剩下的照抄,some 改成any,my改成your等句点改成问号;2、把can,shall, will等放到句首,剩下的照抄,some 改成any,my改成your 等句点改成问号;例如：陈述句: They are in the park. He can play the guitar..一般疑问句: Are they in the park Can he play the guitar把下列句子变成一般疑问句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.__________________________________________3、上述都没有的,在句首请助动词Do/Does/Did帮忙,剩下的照抄,some 改成any,my改成your等句点改成问号;例如：陈述句: I like the ducks. He likes the dogs.一般疑问句：Do you like the ducks Does he like the dogs把下列句子改为一般疑问句;1. We need some masks._________________________________2.

英语肯定句改为否定句、陈述句改为一般疑问句的方法和诀窍㈠肯定句变为否定句的方法——⑴加；⑵变⑴“加”——是指加not。

加not的规则是：原句中有“情助be”时则直接在“情助be”后加not（not可与“情助be”缩写）；原句中没有“情助be”时则需要另加助动词do/does/did, 然后在助动词do/does/did后加not（not可与助动词do/does/did缩写）。

助动词do和does用于一般现在时，did用于一般过去时。

⑵“变”——是指变化某些需要变化的词（因为某些词只能用于肯定句或只能用用于否定句）。

如：some→any（someone→anyone，something→anything，somewhere→anywhere）；and→or；too/also→either[´aiðə; ´i: ðə]；a lot of→many/much等。

另外，使用助动词does/did帮助否定时，原来的谓语动词要恢复原形。

例：1）He can swim. →He can’t swim.2）He will（将，要）swim. →He won’t(will not) swim.3）He is a good swimmer. →He isn’t a good swimmer.4）I have some English books. →I don’t have any English books.5）She can sing and dance. →She can’t sing or dance.6）Li Lei’s father has a lot of money. →Li Lei’s father doesn’t have much money.7）He went to Shanghai last week. →He didn’t go to Shanghai last week.说明：大多数英语肯定句改为否定句都符合上述规则，但也有一些特殊的情况不符合上述规则，在以后的学习中会学到，要注意积累。

一、陈述句：用于陈述事实和观点。

包括肯定结构和否定结构，句末用句号。

二、肯定句→否定句：1.主语+系动词be + 表语。

在be（am\is\are\was\were）后加not；如：The dog is playing in the room. → The dog is not playing in the room.2. 主语 + 情态动词 + 动词原形 + 其他。

在情态动词（can ,should，must ，would）后面加not；如：He can dance.→He can not dance.3.主语+实义动词+其他。

要借助助动词do , does, did;①句中动词为原形的，加don’t .如：I like apples. →I don’t like apples.②句中动词为三单式的，加doesn’t，并将三单式的动词还原成原形。

如：He likes apples.→ He doesn’t like apples.③时态为过去时的,要加didn’t 而且动词过去式要改为原形,如:I went to school yesterday .→I didn’t go t o school yesterday .注：肯定句中的some、something、somebody等在否定句中分别改成any、anything、anybody等，already要改成yet，too改成either, both改成neither, all 改成none等。

如：There are some students in the classroom.→There are not any students in the classroom.三、肯定句→一般疑问句——三步法●一般疑问句：只能用yes（是）或no（否）来回答的疑问句。

一般结构：系动词be/情态动词/助动词+主语+其他成分通常回答：肯定：Yes，主语+提问的系动词be/助动词/情态动词.否定：No，主语+提问的系动词be/助动词/情态动词的否定形式. 如：① Is she from America? 她来自美国吗？-Yes, she is. / No, she isn't. 是的，她是。

初一英语句型转换陈述句变一般疑问句和否定句1 I can help you. 2 Tom’s T-shirt is five dollars. 3 I often watch TV on Sunday. 一、陈述句变一般疑问句的方法：1．对于助动词、情态动词、be动词作谓语的，动词作谓语的，把把be动词，can，shall， will, may等放在句。

如：首，（some 改成any，my改成your等），句点改成问号。

如：He's a teacher. →Is he a teacher? He c an swim. →Can he swim? He'd like to go there. →Would he like to go there? 2、含有have的一般疑问句,have译为“有”。

一般疑问句式有两种形式: 1.把have/has调到句首。

例如: 陈述句:Tommy has a computer. 一般疑问句:Has Tommy/he a computer? 2.加助动词do/does,第三人称单数用does,其他人称用do，过去式用did。

其句型例如上句可变为: 主语 + have...?例如上句可变为为:Do/Does + 主语Does Tommy have a computer? 3．对于实意动词作谓语的，动词原型借助do，三人称单数借助does，过去式借助did，加在句首，再把谓语改为动词原形，（some 改成any，my改成your等），句点改成问号。

其句型为:Do/Does/did + 主语 + 动词原形+其它如：如：I like him. →Do you like him? He likes me. →Does he like me? I liked him. →Did I like him? 注意：在把肯定句改成否定句或一般疑问句的时候,要注意句中是否有already、some、something、somebody等词，如果有也必须进行改变，already要改成yet，some、something、somebody等分别改成any、anything、anybody等。

英语中陈述句变一般疑问句的口诀在英语学习中，陈述句变一般疑问句是一个重要的语法点。

掌握这个转换规则对于正确理解和运用英语至关重要。

为了帮助大家更轻松地掌握这一知识点，下面给大家分享一个实用的口诀。

“有 be 用 be，有情用情，无 be 无情借 do/does，三单 does 加原形，其他人称用 do。

”接下来咱们详细拆解一下这个口诀。

“有 be 用be”，意思是如果陈述句中本来就有 be 动词（am/is/are/was/were），那么在变一般疑问句时，直接把 be 动词提到句首。

比如，“She is a teacher” 变成一般疑问句就是“Is she a teacher?” 再比如，“They were happy yesterday” 变成一般疑问句就是“Were they happy yesterday?”“有情用情”指的是如果陈述句中有情态动词（can/could/may/might/must/should/ought to/will/would/need等），变一般疑问句时，将情态动词提到句首。

例如，“He can swim” 变为一般疑问句就是“Can he swim?” 又如，“We should study hard” 变成一般疑问句就是“Should we study hard?”“无 be 无情借do/does”，这是说当陈述句中既没有 be 动词，也没有情态动词的时候，就要借助助动词 do/does 来帮忙。

具体用 do 还是does，取决于主语。

“三单 does 加原形”，如果主语是第三人称单数（he/she/it 或者单个的人名、事物名称等），我们就用does，并且后面的动词要变回原形。

比如，“He likes apples” 变成一般疑问句就是“Does he like apples?” 这里注意，likes 要变回 like。

“其他人称用do”，除了第三人称单数之外的其他人称（I/we/you/they 等），我们用 do 来构成一般疑问句，后面的动词用原形。

●am not（无缩写形式）●is not（缩写：isn’t）●are not（缩写：aren’t）【肯定句】He is a driver.【否定句】He is not a driver.【第二种情况】●句中有情态动词；●直接在情态动词后加not。

中学阶段常用的情态动词：●can【可以】→ can not或cannot（缩写：can’t）●could【可以，can的过去式】→could not（缩写：couldn’t）●shall【将要，应该】→ shall not（缩写：shan’t）●should【将要，应该】→ should not（缩写：shouldn’t）●may【也许】→ may not（缩写：mayn't）●might【也许】→ might not（缩写：mightn’t）●will【将要】→ will not（缩写：won’t）●would【将，愿意】→ would not（缩写：wouldn’t）●must【很可能，必须】→ must not（缩写：musn’t）【肯定句】She will come tomorrow.【否定句】She will not come tomorrow.【第三种情况】（1）●句中没有be动词或情态动词；●句子是一般现在时；●直接在动词前加助动词do not。

do not（缩写：don’t）+动词原形【注意】助动词是语法功能词，自身没有词义，不可单独使用，因此没有对应的中文翻译。

【肯定句】They like apples.【否定句】They don’t like apples.【第三种情况】（2）●句中没有be动词或情态动词；●句子是一般现在时；●主语是第三人称单数；●在动词前加助动词does not；●动词变回原形。

陈述句对划线部分提问口诀：（一替，二改，三提，四问号）
提问题并不难，去提部分加特词，一般转完再提特；
问主语（who/what）不变序，其余部分抄原句。

注：疑问词是w或h作词首，所以特殊疑问句可称为wh疑问句，主要是对句子的某一成分进行提问。

特殊疑问词口诀：
什么什么用what，年龄要用how old，who who你是谁，where where在哪里，
whose谁的，how如何，which是问哪一个，when when问时间，what time几点了，
how long问多长，how many/how much问多少，how often问频率，
