Question

as if 的主句和从句有时态上的关系吗?
I saw her yesterday,
1)she looked as if she is ill
2)she looked as if she was ill
3)she looked as if she had been ill
用哪个合适?那个是虚拟表示她不是真病,只是看起来像病,哪个又是指真病.
1)she looked as if she is ill （主句是过去式，从句一般式，可以这样吗？）
2)she looked as if she was ill （主句是过去式，从句也是过去式，是从句用的虚拟语气吗？还是因为主句是过去式？）
3)she looked as if she had been ill

Answer 1

答案显然是第二个 你不要只分析as if的主句和从句 你要看题中的第一句话是我昨天看到了她 说明这个人是在今天叙述昨天发生的事 用这一点就可以判断是过去时了 as if 表达的就是像的意思 在这里并不存在虚拟语气
