Yesterday, Jane walked away from the discussion. Otherwise, she something she would regret

Yesterday, Jane walked away from the discussion. Otherwise, she something she would regret later.
A. had said
B. said
C. might say
D. might have said

A. had saidB. saidC. might say(答案→)D. might have said解析：句意：昨天Jane走开了没有参加讨论。否则的话，她可能会说出一些她以后后悔不迭的话出来。这里otherwise翻译为“否则”，= If she hadn't walked away from the discussion,其后的句子经常会使用虚拟语气。其句子结构等同于if引导的条件状语从句虚拟语气中主句的结构变化。即：如果是对现在/将来情况的虚拟，句子谓语使用“would/could/might do sth”。如果是对过去情况的虚拟，句子谓语使用“would/could/might have done sth”。所以选D。

这下我知道了
