问题补充：

We our lives had it not been for the policeman.

A. would have lost

B. should lose

C. might lose

D. had lost

答案：

(答案→)A. would have lost

B. should lose

C. might lose

D. had lost

解析：因为had it not been for the policeman = if it had not been for the policeman (如果没有警察) ，显然是与过去事实相反的情况，主句中的谓语应是would have lost。
