过去完成时的主动语态和被动语态一、过去完成时的主动语态（1）构成：had+过去分词（2）用法①表示在过去某一时间或动作之前已经发生或完成的动作。它表示这个动作发生的时间是“过去的过去”， 这一过去时间可用by, befre 等构成的短语及 when, befre, after, by the time 等引导的状语从句表示。I had finished my hmewrk befre I had supper.我在晚饭前把家庭作业做完了。
②表示从过去某一时间开始，延续到过去另一时间的动作。这个动作可能还要延续下去，常与fr, since构成的表示一段时间的短语或since 引导的表示一段时间的从句连用。He said that great changes had taken place in his hmetwn since 1990. 他说自从1990年以来他的家乡发生了很大的变化。③表示原计划或打算做某事而没有做成。常用动词有want, mean, plan, hpe, suppse, expect, intend等。They had wanted t help but culdn't get there in time.他们本来是要去帮忙的，但未能及时赶到那里。He had hped t catch the 8: 00 bus, but fund it gne. 他原希望赶上8点的公共汽车，却发现那趟车已经走了。

After he left the rm, the bss came in.他离开房间后，老板进来了。The train left befre he gt there. 他还没到那儿，火车就开走了。
