一道很简单的英语辨析题请求详解how与what的区别为什么用how to deal with ?它与what to do

1.how是副词,在句中只作状语,可以代替副词/介宾短语.
what是代词,在句子做主语/宾语/表语等,可以代替名词/代词.
2.如：What is the weather like today?= How is the weather today?
即：how（副词/状语） = like（介词） + what（宾语/代词）（like what就是介宾短语）
3.而how to deal with sth = what to do with sth
即：deal with sth是一个完整的短语,而how充当它的状语；
而do sth with wth也是一个完整的短语,what代替第一个sth做do的宾语.
4.再如：I want to deal with it.= I want to do something with it.
I don't know how to deal with it.= I don't know what to do with it.
最后一句的what即代替上句的代词something.

一个是副词how，一个是代词what。

how to deal with
what to do with 记住就行了
