Question

It is none of your business( )other people think about you. Believe yourself. A how B what C which

选的是B 为什么，谁能给我分析一下句子结构？

Answer 1

其实It
is
none
of
your
business
是固定搭配，但是It
也是形式主语，这里真正的主语是后面的“what
other
people
think
about
you”，正过来，就是what
other
people
think
about
you
is
none
of
your
business.
在这个选择题里，缺少的是主语，主语可以是名词或者代词，排除A，又因为what
other
people
think
about
you，别人对你的想法是什么，而没有说具体的哪个，所以选what，不选which.
