三年级英语改否定句和一般疑问句English:To change a sentence from affirmative to negative in English, we usually add the word "not" after the auxiliary verb or the main verb. For example, "He is playing soccer" becomes "He is not playing soccer." In the case of a sentence without an auxiliary verb, like "She likes ice cream," we add the auxiliary verb "do" and then "not" to form the negative: "She does not like ice cream." To convert a statement into a general question, we typically invert the subject and the auxiliary verb. So, "You are happy" becomes "Are you happy?" However, if there's no auxiliary verb, we add the appropriate form of the verb "do" before the subject to form the question: "They like pizza" becomes "Do they like pizza?"中文翻译:将英语中的肯定句改为否定句通常在助动词或主要动词后面加上“not”。
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。

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。
