書名：Barron's TOEIC
版本：6/e
頁數：144 第16題
題目：
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
疑問：為甚麼是C而不是A
根據書前面的文法解析，
假設句的公式應該是
(1)If +主詞+過去式動詞，主詞+would +原V
=>表示與現在事實相反的假設
(2)If +主詞+had+p.p, 主詞+would have p.p
=>表示與過去事實相反的假設
題目中的主要字句是would be working應該屬於第一種用法，為何答案是C?
請高手解答,TKS!!!!
