高中英语 Module4 Carnival（Period4）导学案 外研版必修5-外研版高二必修5英语学案

Period 4 Grammar (Review of the Passive Voice)学习目标：1. 扎实复习本模块语法被动语态，提升综合语言运用能力。2. 自主学习，探究共赢；学会分析与总结的方法并学以致用。3. 激情投入，惜时高效，体验进步的快乐。学习重点：被动语态。学习难点：被动语态的正确运用。课前预习学法指导：1. 借助课本和辅导材料，初步感知被动语态。2. 完成时间 15 分钟。教材助读：被动语态(一) 语 态 分 类 英语动词有两种语态，主动语态和被动语态。主动语态表示主语是动作的执行者，被动语态表示主语是动作的承受者。如：Mark Twain wrote this book. (主动)This book was written by Mark Twain.(被动)He is feeding a dog. (主动)A dog is being fed by him. (被动)被动语态结构：助动词 be + 及物动词的过去分词构成。(二) 被动语态的时态、人称和数的变化 主要体现在 be 的变化上，其形式与系动词 be 的变化形式完全一样。以 do 为例，如下：一般现在时：am / is / are + done 一般过去时：was / were +done 一般将来时：shall / will + done 一般过去将来时：should / would + done 现在进行时：am / is / are + being + done过去 进行时：was / were + being + done 现在完成时：have / has + been + done过去完成时：had + been + done 将来完 成时：shall / will + have been + done过去将来完成时：should / would + have been + done ［注］被动语态没有将来进行时和过去将来进行时。（三）被动语态考查要点简述被动语态的构成方式：be + 过去分词，口语只也有用 get / become +过去分词表示。被动语态的基本用法：不知道或没必要提到动作的执行者是谁时用被动语态。强调或突出动作的承受者常用被动语态（by 短语有时可以省略）。 （1）使用被动语态时应注意的几个问题。① 主动变化被动时双宾语的变化。看下列例句。My friend gave me an interesting book on my birthday.An interesting book was given to me(by my friend)on my birthday.I was given an interesting book (by my friend)on my birthday.② 主动变被动时，宾补成主补（位置不变）；（作补语的）不定式前需加 to。The boss made him work all day long.He was made to work all day long(by ...
