Question

________ when the door burst ______.

A. Hardly did he collect the papers on his desk; opened

 B. No sooner had he collected the papers on his desk; opened

 C. Hardly had he collected the papers on his desk; open

 D. No sooner did he collect the papers on his desk; open

Answer

C

【解析】考查倒装句和时态。Hardly…when…一…就…；该句型中hardly后面要使用部分倒装。根据句意可知使用过去完成时。Open是形容词，在句子中做补足语。句意：他一把桌子上的报纸收起来，门就被推开了。故C正确。
