1 2013 年月日第周星期 Unit 10 By the time Igot outside, the bus had already left. 过去完成时态专项训练撰写: 执教: 学****目标: 掌握过去完成时态的构成和用法。学****重点和难点: 过去完成时时态的运用重点语法: 过去完成时时态㈠构成过去完成时态由“助动词 had ( 用于各种时态和数)+ 过去分词”构成。否定式: had not + 过去分词缩写形式: hadn ’t ㈡用法: ①过去完成时态表示在过去某一时间或动作之前已经完成的动作,它表示动作发生的时间是“过去的过去”。它是一个相对的时态,只有在和过去某动作进行比较时才可用到它。过去完成时态常与 by, by the time, before, by the end of 等介词短语或时间状语从句搭配。如: By the time he was ten, he had learned 200 English words. 到十岁时, 他已经学****了二百个英语单词。 I had seen you before you saw me. 在你看到我之前,我已看到了你。②表示从过去开始,持续到过去某一时间的动作或状态。常与 for 引导的一段时间连用,此时谓语动词只能用表示延续性的动词。 He had studied English for two hours when I called him. 当我给他打电话时, 他已经学英语两个小时了。③用在宾语从句中, 主句谓语为一般过去时态时, 从句用过去完成时态, 代替现在完成时态或一般过去时态。如: The teacher asked me what had happened to me. 老师问我发生了什么事。㈢过去完成时态和一般过去时态的区别: 两者都表示过去的动作,但是一般过去时态表示的是相对于现在的过去时间,而过去完成时态表示的是相对于过去某一时刻的过去,即过去的过去。如: They had finished that work yesterday. (×) They finished that work yesterday. (√) 他们昨天完成了那项工作。 Most of students arrived before 4 yesterday afternoon.( ×) Most of students had arrived before 4 yesterday afternoon. (√) ㈣当两个或两个以上接连发生的动作用 and 或 but 连接时, 按时间顺序, 只需用一般过去时态。如: She took up her schoolbag, locked the door and went to school by bike. 她拿起书包,锁上门,然后骑着自行车去上学了。 2 当堂达标︰单项选择()1.
