题目

It is only when we are taking a test ___ we are not prepared for it .
A.do we realize B.that we realize C.we realize that D.do we realize that

答案

选择B,不要被迷惑.only when····test是状语,故可判断这是个强调句式,用“It is或was···that···”不用倒装.这个句子相当于对“Only when we are taking a test do we realized we are not prepared for it "状语部分的强调.
