选择题
________ 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
答案
答案：C
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。
