why don't you ; why not ; what about 三者的区别与用法
答
三者都是提建议的句型.Why don't you +动词原形……?Why not +动词原形……?What about +动词ing 形式……?例如：Why don't you go to the park on foot?=Why not go to the park on foot?=What about going to the ...能详细解释一下使用时的区别吗三者所表达的意思是一样的，只是后面所跟的动词形式稍有区别。Why don't you 和Why not 后面跟动词原形，What about 后面跟动词ing 形式。另外，Why don‘t 后面必须有you 或者we ，Why not 后面直接跟动词。别的没有什么区别。
