優(yōu)質(zhì)解答

have not 和haven't沒(méi)有區(qū)別,都是現(xiàn)在完成事態(tài)的否定用法.haven‘t是縮寫(xiě)
e.g.:I have finished my homework
變否定：i have not finished my homework
變疑問(wèn)：have you finished your homework?
don't have是一般現(xiàn)在時(shí)的否定形式.要求主語(yǔ)為第一人稱,have此處做“擁有”翻譯
e.g.:I have a cat
變否定：i don't have a cat
變疑問(wèn)：do you have a cat?
