Discussion在故事中，为什么分别使用一般过去时和过去完成时？在使用不同时态时，这些句子的动作有什么先后顺序？ 过去完成时由“助动词had(用于各种人称和数)+过去分词”构成，表示某动作或状态在过去某一时间或动作之前已经发生或完成，它表示动作发生的时间是“过去的过去”。语法概述过去的过去过去某时现在将来过去完成时从过去之前的某个时间点到过去的某个时间点为止（先发生）（后发生）GrammarFocus WhenIgottoschool,IrealizedthatIhadleftmybackpackathome.BythetimeIgotbacktoschool,thebellhadrung.BeforeIgottothebusstop,thebushadalreadyleft.IwasabouttogouptomyofficewhenIdecidedtogetacoffeefirst.AsIwaswaitinginlinewithotherofficeworkers,Iheardaloudsound.Readthefollowingsentencesandclassifythemaccordingtodifferenttenses. 主句为过去完成时，从句是一般过去时，主句动作发生在从句之前。两个动作同时进行,主、从句都是一般过去时或过去进行时。WhenIgottoschool,IrealizedthatIhadleftmybackpackathome.BythetimeIgotbacktoschool,thebellhadrung.BeforeIgottothebusstop,thebushadalreadyleft.IwasabouttogouptomyofficewhenIdecidedtogetacoffeefirst.AsIwaswaitinginlinewithotherofficeworkers,Iheardaloudsound.
