新手一枚，求助：
怎样在BYU-BNC页面，或者是运用AntConc检索it作that 从句的外置主语和宾语，如It is surprising that he won the game. I should make it clear that you have to take all the responsibility for your decision.

先要大胆设想一下，要检索的可能会出现以下三种type，it is [j*] that, it was [j*] that, it [j*] that。再对检索结果进行核对，看是不是有遗漏或者是结果中有不符合要求的instances，如果有则对表达式进行调整，如果表达式无法过滤则只能手工操作了。

但是IT做外置主语不仅It +be+adj +that 这种情况，还有It +be +a(an)+n+tha, It +v+that 等等情况。这个怎么办呢？
