Question

Often, when he ______ something that ______ him, he wasted his time drawing some little pictures.

A．should be doing; gave

B．should have been doing; was given

C．should do; was given

D．should have been doing; had given

Answer 1

B

根据第二空先行词something 和定语从句谓语动词give之间为被动关系，故排除A、D。句意：他经常是在本应该做那些分配给他的工作的时候，把时间浪费在画画上。题干中的时间住处为过去时，故应为本应该做某事，排除C项。
