重点语法含有be动词的句型转换肯定句变否定句
重点语法含有be动词的句型转换肯定句变否定句一、肯定句变否定句的基本原则在转换肯定句变否定句时，我们需要根据句子的结构和语法规律来进行相应的调整。
以下是一些常见的句型转换规则：1.句子结构为主语 + be动词 + 表语肯定句：主语 + be动词 + 表语否定句：主语 + be动词的否定形式（比如is not, am not, are not）+ 表语肯定句：She is a doctor.否定句：She is not a doctor.2.句子结构为主语 + be动词 + 表语 + 其他成分肯定句：主语 + be动词 + 表语 + 其他成分否定句：主语 + be动词的否定形式 + 表语 + 其他成分肯定句：They are studying English in the library.否定句：They are not studying English in the library.3.句子结构为主语 + be动词 + 其他成分肯定句：主语 + be动词 + 其他成分否定句：主语 + be动词的否定形式 + 其他成分肯定句：He is sleeping right now.否定句：He is not sleeping right now.二、特殊情况下的句型转换规则除了上述基本原则外，还有一些特殊情况需要特别注意。
1.当be动词为am时，否定形式为am not，而不是is not或are not。
肯定句：I am happy.否定句：I am not happy.2.当be动词为is时，否定形式为is not，而不是am not或are not。
肯定句：It is a beautiful day.否定句：It is not a beautiful day.3.当be动词为are时，否定形式为are not，而不是am not或is not。
肯定句：We are good friends.否定句：We are not good friends.通过上述规则和例子，我们可以清楚地了解如何将重点语法含有be动词的肯定句转换成否定句。

( 变换成为一般疑问句并回答)____________________________________________________be 动词用法练习题（ 2）1.选择正确的 be 动词填空。
否定句及一般疑问句
句型转换肯定句变否定句及一般疑问句一、肯定句变否定句1、含有be动词的否定句规则：在be动词后+not.（is not可缩写成isn’t ；are not可缩成aren’t，但am 与not不可缩写）eg:肯定句：I am a student.否定句：I am not a student.肯定句：She is my sister.否定句：She isn’t my sister.肯定句：They are my parents.否定句：They aren’t my parents.2、含情态动词的否定句规则：在情态动词后+ not（can not 可缩写成can’t ，must not 可缩写成mustn’t ）eg:肯定句：I can spell “English”.否定句：I can’’t spell “English”.English”.肯定句：I must find it.否定句：I mustn’t find it.3、含有实义动词的句子的否定句构成（1）第三人称单数做主语。
（he、she、it或表示单个人或物的第三人称名词）规则：要在行为动词前加上助动词doesn’t，然后将动词恢复原形。
eg ：肯定句：He has a soccer ball.否定句：He doesn’t have a soccer ball.（2）其它人称做主语规则：在行为动词前加don’t ，句子中的行为动词用原形。
eg:肯定句：They like bananas.否定句：They don’t like bananas.注：（1）在变否定句时，如遇some应变any Here are some books.Here aren’t any books.二、肯定句变一般疑问句1、含有be动词的句子变一般疑问句规则：把be动词提至句首,第一人称变第二人称，句末句号变问号。
（I/we变成youMy/our变成your）肯定句：I am a student.一般疑问句：Are you a student?肯定句：She is my sister.一般疑问句：Is she your sister?肯定句：They are my parents.一般疑问句：Are they your parents?2、含有情态动词的句子变一般疑问句规则：把情态动词提至句首,第一人称变第二人称，句末句号变问号。
Be动词
Be动词口诀:我I用am，你you用are，is跟着他he,她she,它it.单数名词用is，复数名词全用are变否定，更容易，be后not加上去变疑问，往前提，句末问号莫丢弃。
还有一条须注意，句首大写要忘记。
1、be动词包括am, are, is。
2、be动词的用法。
am →主语是单数第一人称（即I）。
e.g. I am…be are →单数第二人称及所有复数。
e.g. You are…The coats are…is →单数第三人称及不可数名词。
e.g. Your father is…The money is…3、否定句式（即改否定句）：在be动词之后+not, 句子其它部位不变。
e.g. He is not a teacher.4、缩写形式。
①主语+be，缩写be第一个字母为’，再与主语合并。
e.g. you are →you’re Jack is →Jack’s②be+not否定形式的缩写，缩写not中“o”为’, 再与be合并。
e.g. is not→isn’t are not →aren’t③不能缩写的情况：this is, these are, those are, am not及缩略的肯定回答。
e.g. Yes, I am. (I’m 误)5、含be动词句子的疑问句型转换。
①一般疑问句：将be动词提前，其它照抄不变，最后+？，读升调。
（一般第一人称改为第二人称）e.g. The man in the car is her father. →Is the man in the car her father?I’m a middle school student. →Are you a middle school student?②一般疑问句的肯否定回答。
肯定回答：Yes, 主语+be. 否定回答：No, 主语+be+not.e.g. Is he old? Are you a new student? Is your father at home?Yes, he is. Yes, I am. Yes, he is.No, he is not.(isn’t) No, I’m not. No, he is not.(isn’t)注意：①主语必须用代词回答；②肯定回答不能缩写；③回答第二人称，用第一人称回答。

关于否定句知识及练习题人教版英语七年级上册
人教版英语七年级上册关于否定句相关知识及其练习巩固在英语试题中，有一种题型叫做句型转换，包括同义句、对划线部分提问、改为一般疑问句、否定句、做肯定或否定回答、合并句子等。
今天，我们给大家讲一讲如何变为否定句。
一、关于否定句的构成。
1、含有be动词的陈述句变为否定句，在be（is \ am\ are）后面加上not , 即is not = isn’t ; are not = aren’t ; I am not = I’m not 等等。
例如：I’m in Class 1 , Grade 7.我在七年级一班。
I’m not in Class 1 , Grade 7. （否定句）我不是在七年级一班。
又如：The girl is my sister. 这个女孩是我的妹妹。
The girl isn’t my sister. （否定句）这个女孩不是我的妹妹。
再如：Tom and Alice are classmates. 汤姆和爱丽丝是同学。
Tom and Alice aren’t classmates.（否定句）汤姆和爱丽丝不是同学。
练习巩固：举一反三（1）、I am Lily’s friend. （改为否定句）I _______ _______ Lily’s friend.（2）、Mr. Brown is my English teacher. （改为否定句）Mr. Brown ________ my English teacher.（3）、They are my parents. （改为否定句）They ________ my parents.参考答案：1、am not 2、isn’t 3、aren’t2、含有情态动词can的否定句，直接在can后面加上not.例如：I can say the word “ruler”. 我会说ruler这个单词。
改为否定句：I can’t say the word “ruler”. 我不会说ruler这个单词。
