、肯定句改否定句的方法
1、 在be动词后加not。如：
is not ， are not ， am 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。如：
① I am a girl.
→ I am not a girl.
②You are a student.
→You are not a student.
→You aren't a student.
③This is Tom's bag.
→ This is not Tom's bag.
→ This isn’t Tom's bag.
二、肯定句改一般疑问句的方法
1、 把be动词放在句首，剩下的照抄。（some 改成any，I改成you，my改成your，）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，I 改成you，my改成
your，）句点改成问号。
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，I改成
you，my改成your，）句点改成问号。注意：句
首的第一个字母要大写，句尾标点应为“？”。
①I am in Class 6.
→Are you in Class 6?
②You are from America.
→Are you from America?
③It is an orange.
→Is it an orange?
4、 就一般疑问句回答一般疑问句有两种回答，即：肯定回答和否定回答。其中，肯定回答用yes,否定回答用no。 语句顺序为：Yes + 主语 + am /is/ are/was/were.|can.|do/does/did|; No + 主语+ am not/ isn’t/ aren’t 如：—Are you an English teacher?→Yes, I am. /No, I am not.—Is that a bird? →Yes, it is./ No, it isn’t.
三、对划线部分提问口诀
一代： 用正确的疑问词代替划线部分；
二移： 把疑问词移至句首；
三倒： 颠倒主谓语，但对主语或其定语提问时除外（some 改成any，I改成you，my改成your）；
四抄： 照抄句子剩余部分；
五变：把句末句号变为问号。
以特殊疑问词或词组开头的句子叫特殊疑问句。
