答：B
译：要是没有你的帮助，我们决不可能完成这项工作。
析：最佳E：But (for) ... = If it had not been for.... 要不是因为。。。的话。
我们知道，虚拟条件句中如果有助动词had的话，可以通过部分倒装的方法省略if:
Had it not been for...=If it had not been for...
D选项纯粹是一个凑数的干扰项。A的错误更大，没有if,也没有倒装，更不能反映对过去情况的虚拟。AD很容易排除。最大的干扰项是C，因为，我们平时见过这样的句式：Haven't I told you before? 我以前难道没有告诉过你吗？但这是两码事。语法书上，关于虚拟语气，没有见到过这样的例子。 语言不是数学，不能凭空推理。碰到这样的题，还是乖乖地按语法书上说的去做吧。
C到底对不对，行不行，我不敢下结论。但我可以肯定地告诉，选C不得分。选B，能得分。
听雅哥，没错的。

Answer 2

选B
这里运用的是虚拟语气。
首先主句用的是would have done,
而且这里没有时间错综的情况，
是对过去的假设，所以主句应该用if....had done,
而B选项就是倒装形式，
所以将had提前。
因此，选B

Answer 3

C。对过去事实的虚拟。省略了If.原形为：If it had not been for your help.......
