变否定句和疑问句
变否定句：
1.先找句中是否有be动词（am，is，are，was，were）或情态动词
（can，may，must，will，would，shall ，should，could，），如果有，在be动词或情态动词后加not。
2.如果句中没有be动词或情态动词，则借助动词的否定形式don’t，
doesn’t（用于三单）或didn’t（用于过去时态）。

变否定句和一般疑问句的小窍门
如何做句型转换一、如何变否定句先看句子中有没有系动词am,is are,was,were 和情态动词can,may,must,need,will和would，1、如果有的话，变否定句时就在这些词后加not例如：He is my friend.—He is not my friend.You can sing songs.—You can’t sing songs.2.如果没有那些词的话，就在主语之后，谓语动词之前加don’t或doesn’t。
加don’t 还是doesn’t ，主要取决于动词的形式A：动词用原形时，在它的前面加don’t，动词本来是原形，不需要变化。
例如：We make lunch every day.—We don’t make lunch every day. B: 动词用单三时，在它的前面加doesn’t，然后将动词变为原形；例如：He wants apples for lunch .—He doesn’t want apples for lunch .二、如何变一般疑问句先看句子中有没有系动词am,is are,was,were 和情态动词can,may,must,need,will和would，1、如果有的话，就将他们提前大写加问号“？”例如：He is my friend.—Is he your friend？I can sing songs.—Can you sing songs?2、如果没有那些词的话，就在句首加Do或Does。
加Do还是Does，也取决于动词的形式A：动词用原形时，在句首加Do，动词本来就是原形，不需要变化。
We make lunch every day.—Do you make lunch every day?B: 动词用单三时，在句首加Does，然后将动词变为原形。
例如：He wants apples for lunch . —Does he want apples for lunch ?。
