2024下半年英语六级语法考点精练：If条件句中的虚拟语气
If 非真实条件句所表示的假设是不可能或不大可能发生或实现的，句中的主句与从句都用虚拟语气，其构成如下：
与现在事实相反：
从句：动词的过去式(be为were)
主句：would (should, could, might) + 动词原形
与过去事实相反：
从句 ：had + 过去分词
主句 ：would (should, could, might) + have + 过去分词
与将来事实可能相反：
从句：动词过去式(should + 动词原形， were to + 动词原形)
主句 ：would (should, could, might) + 动词原形
例句：
If I had time, I would go to the movies with you.
If we hadn’t made adequate preparations, the conference wouldn’t have been so successful.
If it were to rain tomorrow, the game would be put off.
几种特殊形式：
1)在非真实条件句中，有时从句的动词所表示的动作和主句的动词所表示的动作并不同时发生，在这样的条件句中使用的虚拟式称为混合虚拟式。其构成视具体情况而定。例如：
If I had taken my raincoat when I came out this morning, I would not be wet now.
If I were you, I wouldn’t have missed the film last night.
2)引导非真实条件从句的连词if在正式文体中有时可以省去，were, had, should等非行为动词这是应提到从句句首。例如：
If I were you, I wouldn’t feel sorry.
Were I you, I wouldn’t feel sorry.
3)不用if引导的虚拟条件句时，without, but for, but that, otherwise等同样表示虚拟。例如：
But for your help, they couldn’t have succeeded.
She wasn’t feeling well. Otherwise, she wouldn’t have left the meeting so early.
