By the time I got outside, the bus had already left.当我出来的时候，公共汽车已经走了。本句是by the time引导的时间状语从句，从句是I got up，是一般过去时。主句the bus had already left是过去完成时。过去完成时表示在过去某个时间之前已经发生的动作或一直延续的动作或状态。它表示的动作所发生的时间是“过去的过去”，常用“助动词had+过去分词”构成。常与过去完成时连用的时间状语有：by(the end of)+过去的时间，for+段时间，since+点时间，when引导的时间状语从句(从句中谓语动词用过去时)等。例句：1）By the end of the match, they had kicked two goals and we had kicked four.到比赛结束时，他们已踢进两个球，我们进了四个球。”2）By the time she got up, her brother had already gone into the bathroom. 在她起床之前，她的弟弟已经进了盥洗室。【针对练习】1) Why didnt you go to the movie yesterday?
