The woman’s condition is such that she would have been unable to communicate to staff that she was pregnant or that she had been assaulted.
问题:she would have been unable to xxx 此处时态如何理解?
would have been unable to communicate,是 “would + 完成式” 结构。它有两层意思:
1. 对过去情况的推测。意为“(在过去当时)可能无法表达”。
2. 与过去情况不符或相反的虚拟语气。意为“原本无法表达,而实际却表达了”。
根据句意,本句属于第一种用法。
would have done,可以表达两种情况:
1. 表示与过去情况不符或相反的虚拟语气。例如:
If we had not had enough rain last year, we would not have gained a good harvest. 如果去年雨水不充足的话,我们就不会有一个好的收成。
这句话的含义是:去年雨水充足,我们粮食取得了好收成。
2. 表示对过去发生事情的可能性推测。例如:
People are recycling many things which they would have thrown away in the past. 现在人们都在回收他们过去可能会丢弃的东西。(2014安徽高考试题)
