Question

【题目】Hardly ________ when she ________ someone knocking at the door.
A.did she sit, heard
B.did she sit, had heard
C.had she sat, had heard
D.had she sat, heard

Answer 1

【答案】D
【解析】考查倒装句和时态。本句中放在句首的副词hardly，是一个表示否定含义的副词，放在句首谓语动词要使用部分倒装的形式。且hardly....when....意为“一...就...”，主句的动作发生在从句之前，时态要保持一致。句意：她一坐下来就听见有人敲门。故D正确。
