So it is a bit confusing when Vos Savant fields such queries from the average Joe (whose IQ is 100) as, what's the difference between love and fondness; Or what is the nature of luck and coincidence?
这个as是什么用法呢?后面不是该有名词吗?
这里的 as 后面没有接名词,接的是从句 what..., or what...
such...as what...or what...
由于as后面接的是两个并列的句子, 所以其后加了个逗号。
