Question

Not until he went through real hardship ________ the love we have for our families is important.

A．had he realized B．did he realize

C．he realized D．he had realized

 

Answer 1

B

【解析】B　考查倒装句。句意：直到他经历了真正的困难，才意识到我们热爱家人的重要性。“Not until...”置于句首，主句需要部分倒装，所以排除C和D项。分析题干可知，主句与从句中的谓语动词都表示过去发生的动作，但是不强调两个动作的先后顺序，所以排除A项，选B项。
