Yesterday,Jane walked away from the discussion.Otherwise,she

答案：D.
翻译：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后悔不迭的话出来.
此题考查含蓄的虚拟语气.
1.otherwise翻译为“否则”时,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”.
2.如：We need oxygen.Otherwise,we would die soon.
= We need oxygen.If we had no oxygen,we would die soon.
此句是对现在情况的虚拟.
再如：He didn't go out last night.Otherwise,he would have met you.
= He didn't go out last night.If he had gone out last night,he would have met you.
3.此题请楼主注意前句：Yesterday,Jane walked away from the discussion.
它使用了一般过去时,所以后句是对过去情况的虚拟.
可以同样做如下理
Otherwise,she might have said something she would regret later.
= If she hadn't walked away from the discussion,she might have said something she would regret later.

D
昨天，简从讨论会中走开了。不然，她可能会说一些她会后悔说出的话。
这是一种对过去的猜测，也是一种虚拟语气。walked away from 不是固定词组吗。1. 轻易地胜过 2. 从...安然脱身对啊。就是 从...安然脱身.....。。所以她没有一直参加讨论了，中途走人了...

选D 昨天简走了，否则她可能说一些以后会后悔的话。因为有otherwise，后面的并没有发生，是假设的，要有might，用完成时表示对事情发生后的影响。所以选Dwalked away from 不是固定词组吗。1. 轻易地胜过 2. 从...安然脱身不用当它有什么固定词组的含义，就是走开了，离开了讨论，而且这个不影响做题的...
