书名：Barron's TOEIC
版本：6/e
页数：144 第16题
题目：
If the consultant __________ that we should hire more staff, Helen wouldn't b
e working here now.
(A) didn't recommend
(B) doesn't recommend
(C) hadn't recommended
(D) wasn't recommending
疑问：为什么是C而不是A
根据书前面的文法解析，
假设句的公式应该是
(1)If +主词+过去式动词，主词+would +原V
=>表示与现在事实相反的假设
(2)If +主词+had+p.p, 主词+would have p.p
=>表示与过去事实相反的假设
题目中的主要字句是would be working应该属于第一种用法，为何答案是C?
请高手解答,TKS!!!!
