【本期答案】

                         , I d have done it myself.  

A) If I would have known it        B) If I had have known it          C) Had I known it               D) Should I known it  

【译文】 要是我知道，我就自己把它做了。  

【分析】 此题为语法题，考查虚拟语气的省去 if 的形式。  

if 条件句中包含有 should, had, were

则可省去 if 并把 should, had, were 移到句首

构成倒装句式

而意思不变。  

                         , I d have done it myself.  

A) If I would have known it        B) If I had have known it          C) Had I known it               D) Should I known it  

虚拟语气，C答案中省略了IF。原句是If i had kown it.
