 The twins look the same，even their father finds ________ difficult to tell them from each other.（　　）
  • A.  that
  • B.  this
  • C.  it

题目解答

答案

that那；this这；it它。find it+形容词+to do sth."发现做某事是......"固定搭配，it作形式宾语，不定式是真正宾语。
故选：C。

解析

此题考查的是固定搭配 "find it + 形容词 + to do sth."，其中 "it" 作为形式宾语，真正的宾语是 "to tell them from each other"。因此，正确答案是 "it"。
