过程 一 作业检查 单词听写 二 新知识的学习 初中英语被动语态的学习初中英语被动语态的学习 I Teaching analysis 被动语态是九年级英语教学中一个比较重要的知识点 九年级英语教材 unit3 unit9 都是关于被动语态的学习 可见这一部分的知识在整个初中英语学习中的 重要性 历届广东省中考题中屡见不鲜 出现的频率相当高 几乎可以归结为必考知识 点 其中 情态动词的被动语态及各种时态的被动语态的结构及运用是教学中的重难点 也是大多数学生不容易掌握的地方 因为它是建立在各种时态能够熟练运用的基础之上 因此在进行这一部分知识的学习前 还需要对相应的时态进行概括性的复习 II Students analysis 我的学生名字叫 是东莞中学一名初三的学生 该生性格相对来说是属于比较 沉闷 对于英语的学习兴趣也不是很高 通过接触我发现了 的性格一个特点 那就 是他对于自己感兴趣的东西热情度比较高 具体到他的学习来说 他偏重于理科 数学 物理化学成绩都比较好 而对于像偏文性质的语文英语等科目他是比较薄弱的 所以 对于英语的学习来说 让他有兴趣进入课堂内容的学习是至关重要的 这就要求 在教 学中能够采取必要的课外内容引导 循序渐进的展开教学 例如 对于一些知识点的讲 解 可以穿插进我们日常生活的习惯 一些惯性思维等 在之前时态的讲解的时候 为 了弄清 this morning 这个时间状语到底是过去的时间还是将来的时间 我让他思考我们 平常所说的今天早上 是过去了的时间呢 还是将来的时间 然后根据人的思维模式都 是相同的这一定理让他明白对于一些问题的分析我们要懂得变通与遵循一些定理 规律 他的英语基础很一般 所以我们对于这部分内容的学习的必须在课前做好相应的铺 垫 例如给他重新复习回顾一下之前学过的时态知识 重新强调一下时态的构成等等 然后进入新知识学习的时候 我采用的是比较简单的举例 以形象生动的语文 被 字 句这个知识点来让他首先理解被动语态的概念 然后在一步步进行语法知识要点的学习 当然 还是以比较容易理解的例子让他体会其中的知识结构 知识要点以及做题技巧 III Teaching aims 1 Knowledge aims 熟悉被动语态的基本用法 尤其是情态动词的被动语态 以及不同时态的被动语态 的掌握分析 2

主动语态表示主语是动作的执行者 Eg Many people speak Chinese 谓语 speak 的动作是由主语 many people 来执行的 被动语态表示主语是动作的承受者 即行为动作的对象 Eg Chinese is spoken by many people 主语 English 是动词 speak 的承受者 被动语态的构成 被动语态的构成 被动语态由 助动词 be 及物动词的过去分词 构成 人称 数和时态的变化是通过 be 的变化表现出来的 我们可以通过 被动语态 be 字变 过去分词放后面 这一口诀来记 忆 情态动词的被动语态是由 情态动词 be 及物动词的过去分词 构成 现以 do 为例说明被动语态在各种时态中的构成 情态动词情态动词 情态动词 be done Eg 35 People who drink wine to drive after May day 2011 年 广东 A don t allow B isn t allowed C mustn t allow D mustn t be allowed 一般现在时一般现在时 am is are done Eg 35 Hot water in the students flats from 5 pm to 7 pm now 2012 年 广东 A supplies B is

founded in 1981 这座桥竣工于 1981 年 2 强调动作的承受者 而不强调动作的执行者 Eg The glass was broken by Mike 玻璃杯是迈克打破的 This book was written by him 这本书是他写的 Your homework must be finished on time 你们的家庭作业必须及时完成 此外 有的时候为了修辞上的需要 也可以使用被动语态 例如为了表达特殊的强 调 或者表现出说话主人公的语气 当然 学生在充分理解被动语态这一部分知识点后 只需在具体情况中做出分析 就可以灵活运用 Step 4 主动语态变被动语态 主动语态变被动语态 15 minutes 1 主动语态变为被动语态的步骤 1 将主动句的宾语变为主语 注意 如果主动句的宾语是代词 需将其由宾格变为主格 如 Eg Tom killed him He was killed by Tom I hit him 主 He was hit by me 被 2 将动词改为 be 过去分词 Eg They held a meeting yesterday A meeting was held by them yesterday 他们昨天开会了 3 将主动句的主语改为 by 的宾语 放在谓语动词后 注意 如果原主语是代词 则应由主格变为宾格 Eg He sang a song A song was sung by him 2 主动语态变为被动语态注意的问题 1 主动语态变为被动语态 句子的时态保持不变 Eg I will give him a pen 主 He will be given a pen by me 被 我将给他一支笔 2 在感官动词或使役动词后作补语的动词 在被动语态中用不定式 1 I heard you talk with Peter 主 我听到你和彼得谈话 You were heard to talk with Peter 被 2 I saw her come out of the classroom 主 我看见她出了教室 She was seen to come out of the classroom by me 被 3 含有双宾语 即直接宾语 常指事物 和间接宾语 常指人 的句子 每个 宾语都可变为被动语态的主语 即其被动语态有两种形式 但多以间接宾语作主语 Eg Jack told us the truth 杰克告诉了我们真相 We were told the truth by Jack write make bring 等的被动语态则只能以直接宾语 表物 作主语 Eg You brought me a big cake 主 A big cake was brought to me by you 被 She wrote me a letter 主 A letter was written to me by her 被 Step 5 Exercises 20 minutes 基础练习题 基础练习题 1 用括号内所给动词的正确形式填空 It s said that the long bridge build in two months Which language the
