英语中“How about...”是一句常用的客套话,它后面可接名词、代词或动词-ing形式.
一：当对方谈论的事情不明确,需要询问清楚时,可用这一句型.如：I'd like a cup of tea.How about you?
二：向对方提出建议或请求,相当于句型Would you like...语气很委婉.如：How about having some bread?＝Would you like some?
三：寒暄时用作承接上下文的转折语.如:I'm a teacher.How about you?
四：询问天气或身体等状况.如：1.How about the weather in your city?2.How about your father?
五：征求对方的看法或意见.如：How about this car?
而：how be的用法相对简单,只是单纯的一个疑问句句式.如：how are you?
How is your exam?
简言之,两者的根本区别就在于语境.
用How about带起的句子一定有上文,一般情况下不单独使用,比如：
—Are you okay?
—Yes,how about you?
而how+be 就可以随便带起任何一个问句.
这是我自己总结的,
