问题补充：
高二英语虚拟语气1.If I were to have time,I to the wheatre tomorrow evening.A.should go B.would have goneC.had gone D.were to go 2.What would have happened ,as far as the river bank?A.Bob had walked farther B.
答案：
1.A根据前半句的were to have time可知这是对将来的虚拟（后面的tomorrow evening也暗示如此）.所以后面一般得用would do或者should do
2.C根据前半句的would have happened,可知这是对过去的虚拟,所以后半句要用if Bob had walked farther.但是无此选项,所以可以选择C.将if去掉,则要将if后的主谓倒装
======以下答案可供参考======
供参考答案1:
1.A 对于将来的虚拟，从句用1.were to 2.V-ed 3.should，对于主句，用would/could/should do.
2.C 对于过去的虚拟，从句用had done,主句用would/could/should have done
在if省略的情况下是要将助动词或者BE动词提前，是一定要放在句首的.
供参考答案2:
第2题是倒装，你可以查看语法书中关于虚拟语气的倒装这部分内容
