Question

【题目】My train arrives in Chicago at eight o’clock tonight.The plane I would like to take from there___by then

A.would have

B.will have left

C.has left

D.had left

Answer 1

【答案】B

【解析】句意：我的火车今晚八点到芝加哥。到那时，我想从那里搭乘的那架飞机已经离开了。by意为“到……为止”，而eight o’clock tonight是将来的时刻，所以by then(=by eight o’clock tonight)与将来完成时态连用
