—Why am I so slow at doing the cloze test?
—I guess you didn’t realize the use _____ the contexts.

A．you should have made of	B．you must have made from	C．of which you could have from
D．out of which you need make

答案

A

解析

考查should与动词不定式的完成时连用的含义。should have done表示本来应该做而实际上没做，shouldn’t have done表示本来不该做但实际上做了。本题的问句意思是“我单选题为什么做得那么慢？”，回答“我想你没有意识到你本该好好利用上下文。”
