What about?是一句单独的句子吗?

What about?是一句单独的句子吗? what about 后+Doing sth ,那么what about.的句子中的主语是什么呢? 关于what引导名词性从句,what在句中有实义吗?从句是一个不能单独成立的句子，那从句本意是只做修饰句吗？ what about 的意思 what about 的用法 what about的用法 what about 的意思 What about的中文 what about的同义词 What about的中文 What about you 有这个句子么? about,you,Jane,what?怎么组成句子? what about something eating这个句子对吗 what about的近义词what about=how about=? 用what about与how about各造一个句子 英文从句这样的句子,怎么写才对?……care about what how about color?How about ...How about ...还是用how is the color? what about 可以跟句子吗_______ we moved the sofa over there would that look better?A what aboutB what if C how come what about 跟sth、doing 见了很多.请问这题不选what about 的原因 还有how come 跟什么 what about和how about的区别?
