Question

【题目】_______ Jack not to do that, he wouldn’t have made such a serious mistake.

A. If I persuade B. If I should persuade

C. Had I persuaded D. If I persuaded

Answer 1

【答案】C

【解析】句意：我要是说服杰克不这么做，他就不会犯这么严重的错误了。这里使用了虚拟条件句的省略倒装，根据主句可知是和过去相反的虚拟语气，还原是If I had persuaded Jack not to do that，这里可以省略if，提前had，所以选C。
