一、语法：过去完成时的用法。观察下列句子，找出规律。BythetimeIgotoutside，thebushadalreadyleft.BeforeIwalkedintotheclassroom，theteacherhadstartedteachingalready.HehadfinishedthepaperbytheendofMay.WhenIgottothecinema，thefilmhadbeenonforfiveminutes.上述句子都含有时间状语(从句)。主句为

，

，when引导的时间状语从句(从句使用一般过去时)等。

bytheendof

before

bythetime

一般过去过去完成(
