This camera is of good quality. If it ______ break down within the first year, we would replace it with a new one.

A．would

B．might

C．could

D．should

答案

D 

解析

试题分析：本句的意思是：这台照相机的质量很好。如果它在第一年里出了故障，我们将免费修理。从we would replace it with a new one.可知是对将来的虚拟语气，在虚拟条件句中用以加强假设语气，用“should+do”指将来的情况，当“万一(会)”讲。选D。
