Question

______ in my present work, I would be quite willing to do what you ask me to.

1. A.
   If I am not engaged
2. B.
   If I don’t engage
3. C.
   Were I not engaged
4. D.
   Didn’t I engage

Answer 1

C
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。
