Why not do 和 Why don't do 什么区别
答
Why not do 和 Why don't do 意思表达是一样的，只是形式不同。go是行为动词只能用do,而not用于are等be动词,后跟表语或动名词，如：why don't you go to school?=why not going to school?
你多记一些正确答案，培养一下语感就行了。
答
意思一样
用法上也没什么区别
答
Why not do.....?是向对方提建议的句型.如:Why not go to the zoo this Sunday?可以用why don't you do ....?互换.如上句可写成:Why don't you go to the zoo this Sunday?
答
没有什么区别，但是句型转换上常考。
答
意思是一样的,但用法有点差别 why not 后面直接接动词原形.why don't 后面要先接主语（即名词或代词） 才可以接动词原形.举例 why not come ealier?等于why don't you come earlier?
