Teaching plan 设计教师:源潭中学王珍 教学班级:高二(3)班 课题名称:The Revision of Past Perfect and Past Perfect Continuous 教材版本:北师大版 授课时间:2008年12月23日 一.学生分析 高二(3)班为文科重点班,学生在整体上占有相对的优势,但是由于女生较多,而男生的英语基础薄弱,学生的思维不太活跃,课堂气氛较为沉闷。 二.教材分析 1.本节课的内容是Module6的语法项目,复习过去完成时和 过去完成进行时这两种时态。 2.这两种时态分别出现在Unit16和Unit17中Lesson1的 Grammar 讲解中。 3.时态是高中学生必须掌握的语法内容,但由于学生的英语 基础掌握的不扎实, 他们容易混淆现在分词和过去分词的构成。此外，这两种时态之间又存在着异同点。由于语法点多且杂，大多数学生对语法存在着畏难的心理。因此应采取有效的方法进行语法教学,让学生能够在现实的环境中运用。

初中英语过去完成时语法精讲

公开课教案Unit5 Grammar过去完成时 袁华峰08.10.29教学目标： 1、学习本课生词及用法 2、掌握并运用过去完成时 教学重点及难点：过去完成时的理解及运用 教学手段：多媒体课件 教学过程 一、过去完成时的概念与结构特点 概念：过去完成时表示在过去某一时间或动作之前已经发生或完成了的动作，即“过去的过去（past-in-the-past ）”。 ----|-------------------------- |-------------------------------|----------------------------> 那时以前那时现在 构成：过去完成时由“助动词had + 过去分词”构成，其中had 通用于各种人称。 They had already had breakfast before they arrived at the hotel. She had finished writing the composition by 10 ：00 this morning. 二、过去完成时的判断依据 1. 由时间状语来判定 一般说来，各种时态都有特定的时间状语。与过去完成时连用的时间状语有： （ 1 ）by + 过去的时间点。如： I had finished reading the novel by nine o'clock last night. （ 2 ）by the end of + 过去的时间点。如： We had learned over two thousand English words by the end of last term. （ 3 ）before + 过去的时间点。如： They had planted six hundred trees before last Wednesday. 2. 由“过去的过去”来判定。 过去完成时表示“过去的过去”，是指过去某一动作之前已经发生或完成的动作，即动作有先后关系，动作在前的用过去完成时，在后的用一般过去时。这种用法常出现在： （ 1 ）宾语从句中 当宾语从句的主句为一般过去时，且从句的动作先于主句的动作时，从句要用过去完成时。在told, said, knew, heard, thought等动词后的宾语从句。如： She said that she had seen the film before. （ 2 ）状语从句中 在时间、条件、原因、方式等状语从句中，主、从句的动作发生有先后关系，动作在 前的，要用过去完成时，动作在后的要用一般过去时。如： When I got to the station, the train had already left. After he had finished his homework, he went to bed. 注意：before, after 引导的时间状语从句中，由于before 和after 本身已表达了动作的先后关系，若主、从句表示的动作紧密相连，则主、从句都用一般过去时。如：Where did you study before you came here? After he closed the door, he left the classroom. （3）表示意向的动词，如hope, wish, expect, think, intend, mean, suppose等，用过去完成时表示"原本…，未能…＂ We had hoped that you would come, but you didn't.
