一道几百人都认为模棱两可的英语单项选择题
—Will you please show me how to operate the new machine?
—Sure.It is a piece of cake.Now let me tell you_______to do first.
A:what；B:how.
请说明理由,

Answer 1

A.what
如果用how,需要有宾语it,即how to do it,用what,what在句子中就已经充当了宾语,就不用it了.
题目中Now let me tell you_______to do first.没有it,所以用A.what.
