问题补充:
in my present work, I would be quite willing to do what you ask me to.
A. If I am not engaged
B. If I don’t engage
C. Were I not engaged
D. Didn’t I engage
答案:
A. If I am not engaged
B. If I don’t engage
(答案→)C. Were I not engaged
D. Didn’t I engage
解析:本题考查虚拟语气。根据句意可知考查对现在事实相反的虚拟语气,故从句用一般过去时,C选择项Were I not engaged= If I were not engaged,故选C。
