问题解答:

我来补答
在虚拟语气中,对将来的虚拟If从句有三种表达式:以“万一明天下雨”举例如下:
1) If it should rain tomorrow,I would not.
2) If it were to rain tomorrow,I would not.
3) If it rained tomorrow,I would not.
英语语法规定,虚拟条件句中如果省略If则要求倒装,但只限以i下三个词:should,were ,had可以置于句首,构成倒装,如上述例句1)2)可改为:
1)Should it rain...
2) Were it to rain.
还有一种,对过去的虚拟条件中,如:
If you had followed the teacher's advice,you wouldn't have failed the exam.
可改为:
Had you followed the teacher's advice,you wouldn't have failed the exam.
