【题目】Why didn’t you tell me about your trouble last week? If you _______ me, I could have helped.
A.toldB.had toldC.would have toldD.have told
在线课程【答案】B
【解析】
考查虚拟语气。句意：为什么你上周不把你的麻烦告诉我？如果那时你告诉我，我就能帮上忙。根据上文Why didn’t you tell me about your trouble last week?可知，此处是与过去事实相反的虚拟语气，故if引导的从句中要用had done的形式。故选B。
