选择题
_______ for the doctor’s careful treatment, he _______ till last year.
A．If it is not; can’t live
B．Were it not; couldn’t live
C．Had it not been; couldn’t have lived
D．If it were not; wouldn’t live
答案
答案：C
题目分析：句意：如果没有医生仔细的治疗，他不能活到去年。Had it not been ... 是倒装的虚拟条件句，相当于 If it had not been ...虚拟条件从句中如果有 had, were, should，可省略 if，并将它们提到主语之前，从而构成倒装。 故选C。
考点: 考查倒装句的用法。
