问题 By the time you get to Shanghai tomorrow, I ______ for Chongqing.

选项 A、am leaving
B、will leave
C、shall have left
D、had left

答案 C

解析 将来完成时表示将来某时刻之前或某一行为发生之前所完成的动作。常和by或by the time等结构连用,由“will/shall+have+过去分词”构成。例如:They will have built the hospital by the end of this month.(到本月末,他们将建完这所医院。) By this time tomorrow,they will have repaired the TV set.(明天这个时候,他们会修好这台电视机。)该题是由by the time引导的时间状 语从句,故主句用将来完成时。
