都可以做宾语从句的连接词。what~什么,相当于谈论名词,how~怎样,怎么,谈论状态,方式,例如:I don't know what you said.Do you know how I can get to the station?但是以下这两个句子意思相同:I don't know what to do next.我不知道接下来做什么.=I don't know how to do it next.

二者都可以引导名词性从句,what引导名词性从句其词性为代词,在从句中作主语或宾语,例如:What makes the book so extraordinary is the creative imagination of the writer.What you said at the meeting describes a bright future for the company.也可以是形容词,在从句中作定语,例如:It is not always easy for the public to see what use a new invention can be of to human life.How引导名词性从句,其词性为副词,例如:Scientists study how human brains work to make computers.

这两个词作为疑问词可以引导特殊疑问句,主要区别在词性。what为疑问代词指代不确定的事物,在疑问句中作主语或宾语,例如:What did the teacher said?另外what在疑问句中还可以作为形容作定语,例如:What colour is your bag? how作为为疑问副词,在疑问句中作状语,例如:How often do you go to the cinima ?How does our brain work?
