问题 A beam of light will not bend round corners unless ______ to do so with the help of a reflecting device.

选项 A、made
B、to be made
C、being made
D、having made

答案A

解析本句的意思是：如果没有反射装置，光线不能在拐角处转弯。省略句题：完整的句子应是：unless it is made to do so with the help ofa reflecting device．当部分状语从句的主语和主句主语一致且谓语为be动词时，从句主谓可省略。从句中主语it即主句中的a beam of light，因此可省略。
