__________________________________3.过去完成时常与______________________等引导的时间状语连用。had过去分词when,before,bythetime过去某一时刻或动作之前已经发生或完成的动作。Grammar关于过去完成时的几个考点：1.过去完成时的句型转换。变否定句时，在had后加not，一般疑问句把had提到句首。2.过去完成时的判断依据。①过去完成时是一个相对的时态。只有和过去的某个时间或动作相比较时才会用到。常见的时间状语(从句)由by，before，when，bytheendof，bythetime，until等引导。Grammar过去完成时还可表示过去某一时刻之前发生的动作或状态持续到过去某个时间，常与“for＋时间段”或“since＋时间点”连用。e.g.WhenJackarrived，Maryhadbeenawayforalmostanhour.当杰克到时，玛丽已经离开差不多一个小时了。Grammar③过去完成时经常用于主句为一般过去时的宾语从句中，表示从句动作先于主句动作发生，像在told，said，knew，heard，thought等动词后的宾语从句中。④在表示过去概念的句子中，常出现与完成时态连用的词，如：already，yet，since，for，ever，never及表次数的词，此时句子常用过去完成时。e.g.ImetJiminthestreetyesterday.Wehadn'tseeneachothersincehewenttoBeijing.我昨天在街上碰见了吉姆。自从他去北京后，我们彼此没有见过面。Grammar过去完成时及句型转换口诀：过去的过去之动作，用过去完成时来掌舵。构成“had＋过去分词”结构，切记had是助动词。没错，had

后加not即否定，had提句首有把握，过去分词稳住不用变，上述内容记清好处多。Grammar1.Timwentintothebathroom.Marygotup.
