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。
