The women ran down to assist them in bringing up their seals; but no sooner _____ the house than a voice was heard in the passage, and a man entered.

句意：女人们都跑过去帮他们把所猎的海豹抬上岸，但是他们一回到房子里就听到走廊传来说话声，接着一个男人走了进来。had they re-entered为过去完成时态，no sooner...than...一……就……，no sooner后面要用部分倒装，助动词提前。因为题干后半句为一般过去时，这里只能用过去完成时。
