问题补充：

If my lawyer here last Friday, he me from telling the truth.

A. had been; would have prevented

B. had been; would prevent

C. were; would prevent

D. were; would have prevented

答案：

(答案→)A. had been; would have prevented

B. had been; would prevent

C. were; would prevent

D. were; would have prevented

解析：考查虚拟语气。根据时间状语last Friday，说明指的是过去的情况，所以if引导的从句要用过去完成时，而主句要用助动词+现在完成时。所以选A。
