有do does 和don't doesn't 是不是都用原形啊

有do does 和don't doesn't 是不是都用原形啊 用do/don't或does/doesn't填空 用do,does,don't,doesn't填空 do does don’t doesn't分别是什么意思 用“do,does,did,don’t,doesn’t,didn’t”填空. 用do,does,don't,doesn't,am,is,are或can填空 英语练习题一用do,does,don't,doesn't填空 用do,does,don＇t,doesn＇t,is,have,填 What___do you?I am a teacher.用is,am,are,do,does,don't.doesn' 用do,don't,does'does't填空 doesn't的原形为什么是don't? do后面用动词原形?还是Don't后加动词原形?所有句型都试用么?
