高考英语过去完成时讲解与练习

高考英语过去完成时讲解 过去完成时用法讲练 过去完成时是表示在过去某一时刻以前已经完成的动作或存在的状态，其构成形式为“助动词 had ＋过去分词”。使用过去完成时态的几个典型句型。 一、主语＋过去完成时＋ ①when引导从句（注：从句谓语动词为过去式） ②by短语by the time引导从句（注：从句谓语动词为过去式） ③before引导从句（注：从句谓语动词为过去式）例如： 1．Tom was disappointed that most of the guests __________ when he __________ at the party． A．left；had arrived B．left；arrived C．had left；had arrived D．had left；arrived 此题的正确答案为D。guests先“离开”，Tom后“到达”，“到达”用一般过去时，“离开”用过去完成时。 2．When Jack arrived he learned Mary __________ for almost an hour．（MET’92） A．had gone B．had set off C．had left D．had been away 此题的正确答案为D。因有表示“一段时间”的状语“for almost an hour”，所以选入的动词必须是延续性动词。 3．①We __________ four thousand new words by the end of last year． ②We __________ four thousand new words by the end of this year． A．had learned B．have learned C．learned D．will have learned 句①根据by短语中的last year，正确选项为A；句②根据by短语中的this year，正确选项为D。 4．He had already built his own lab by the time he was ten．到十岁时，他已经建了自己的实验室。 5．He had studied English for five years be
