If only I ______ that was the last chance I could talk to her. I would have said to her, "My dearest mom! I love you."

A、 had known
B、 know
C、 have known
D、 knew

【正确答案】 A

【答案解析】 本题考查条件状语从句。句意：要是知道那是最后一次和她对话，我会告诉她：“我最亲爱的妈妈，我爱你!”从后面的would have said(would have done)，推测出前面If only引导的条件状语从句是对过去事实的虚拟，谓语动词应该用had done的形式。所以答案为A项。
