要看具體上下文語境和情景.
無上下文的情況下可以粗略的認(rèn)為是一致的意思.
但是如果有上下文的情況下：
how about的意思可以細(xì)化為如下
What is your thought,feeling,or desire concerning.
e.g.How about a cup of tea?or How about joining us for lunch?
It is also put as how about it,as in How about it?Do you want to come along?
what about的意思可以細(xì)化為如下
Would you like,as in What about another beer?or What about a game of bridge?
What do you think of,as in So what about renting that white house on the corner?
Why,concerning what,as in I need your frank opinion.What about?
what about it?What should we do,what course of action should be taken.For example,We're supposed to be there at noon and bring two sandwiches eachnow what about it?
Good luck!
