Question

【题目】The plane to Thailand ________ by the time I got to the airport in a hurry.

A. took off B. taken off

C. had taken off D. has taken off

Answer 1

【答案】C

【解析】

句意：当我匆忙赶到机场时，飞往泰国的飞机起飞了。根据时间状语“by the time I got to the airport in a hurry.”可知主句动作发生在前，从句动作发生在后，而从句用的是一般过去时，所以主句该用过去完成时。其构成为had+过去分词，因此答案选C。
