Question

这是一个强调句吗?这句话真的主语是谁
It makes no difference that the forgery 【may have been】 a very skilful one:the bank must recognize its customer's signature.

Answer 1

强调句典型特征,去掉it--that 原句意思不变,语法无误
这句一去掉,就变成makes no diffe.the forgery may have been a 根本语法不对,主语没了
所以这里的IT 起到主语的作用,称为形式主语
由连词that引导的主语从句,在大多数情况下会放到句子的后面,而用代词it作形式主语
It is well-known that the earth moves around the sun.
