Question

一道英语题

--- Would you have called her up _____ possible?
--- Yes, but I _____ busy doing my homework.
A. had it been … was B. if it was … were
C. if it had been … had been D. if it were … would be
请说说理由

Answer 1

1、A正确，先看后面的一个空，不可能选择BD，but一般讲的是事实，后面很难接虚拟语气，找不到过去的时间点，不能用过去完成时，排除C，只能选择A，A的前半部分是虚拟语气饥裤，是对氏亮过去的虚拟，从句用的是if的倒装，此时省略if这个连词，把助歼肢宽动词提前，当然说成 if it had been 也是对的

Answer 2

A. had it been … was
had it been = if it had been
第二空表示亩羡真实情况，我当时正在做家庭作迅汪拍陵液业，用一般过去时

Answer 3

选A
疑问句原形为：
If it had been possible,you would have called her up.
=Had id been possible,you would have called her up.
表示对过去已经仔誉纳发生了的事情的虚拟假设
而回答的话是表示我当时正忙着做家庭念没作业了，所以应该用过虚坦去时态，因此，应该选择was
故，选A

Answer 4

A 由第二空可以得出，第二句是说“我在那个时候一直在干什么”，用过去进行时

Answer 5

选C：if it had been … had been
这是表示与过去事实相反的IF引导的虚拟语气条件状语从句，主句用过去将来完成时，从句用过去渣芦完成时。意思是：如果可能的话，你就会芦梁搭给她打过电话了？（其实没有打过）。是的，但当陪拿时我一直忙于做我的家庭作业（说明当时不可能打，我在做作业，没有空）

Answer 6

C.
与过去事实相反的IF引导的虚拟橘消毁语气条件状语从句，主句用过去将来完成时，从句用过去完成时。另外表示过去一直在做某事时用过去完成进行桥世时圆备。同时有短语be busy doing .
