教学课件 外研英语九年级下册 Unit2 语法专项 —— 被动语态 全解精讲+分层练习 1 1. 掌握被动语态定义、核心句式基本结构 2. 熟练四种常考时态的被动语态变形规则 3. 掌握主动语态变被动语态通用步骤 4. 熟记无被动语态动词与特殊固定句型 5. 灵活应对各类题型，突破易错重难点 学习目标 语态基础概念 英语分为主动语态和被动语态两种句式。 主动语态：主语发出动作，侧重动作执行者。 被动语态：主语承受动作，侧重动作承受者。 被动语态多用于客观介绍、科普、正式场景。 本单元科技、发明话题高频使用被动语态。 被动语态核心公式 通用结构：主语 + be动词 + 过去分词(done) be动词随时态、人称、单复数灵活变化。 过去分词固定不变，无形式改变。 by+动作执行者，可省略，多用于句末。 否定式：be + not + 过去分词 四大时态被动语态汇总表 时态 被动语态结构 一般现在时 am/is/are + done 一般过去时 was/were + done 一般将来时 will be + done 现在完成时 have/has been + done 一般现在时被动语态 结构：am/is/are + 动词过去分词 适用场景：客观事实、日常常规操作。 例句：Many new inventions are used in our life. 译文：许多新发明被应用在我们的生活中。 常用于介绍物品功能、科普类语句。 一般过去时被动语态 结构：was/were + 动词过去分词 适用场景：过去被做的动作、历史发明事件。 例句：This machine was invented many years ago. 译文：这台机器是很多年前被发明的。 一般将来时被动语态 结构：will be + 动词过去分词 适用场景：将来将要被完成的动作。 例句：More high-tech products will be created soon. 译文：更多高科技产品不久将会被研发。 注意：be动词永远用原形，无变形。 现在完成时被动语态 结构：have/has been + 动词过去分词 适用场景：动作已被完成，影响现在状态。 例句：Many traditional skills have been protected. 译文：许多传统技艺已经得到保护。 中考难点：极易遗漏been这个核心单词。 主动变被动四步法 第一步：主动宾语变被动主语。 第二步：根据时态写出对应be动词。 第三步：谓语动词变为过去分词。 第四步：主动主语变by宾语，可省略。 所有陈述句均可套用此通用步骤。 基础句型转换示例 主动：People use computers widely in work. 人们在工作中广泛使用电脑。 被动：Computers are widely used in work. 电脑在工作中被广泛使用。 时态不变，只变换句式结构。 情态动词被动语态 核心结构：情态动词 + be + 过去分词 常用情态：must、should、can、may 例句：The invention should be improved continuously. 译文：这项发明应该被不断改进。 考点：情态后必加be，不能直接加done。 不定式被动语态 结构：to be + 动词过去分词 含义：有待被做、需要被完成。 例句：The new project is to be finished next week. 译文：这个新项目将于下周被完成。 无被动语态动词（必考） 不及物动词无被动语态，永远用主动形式。 高频词：happen、take place、appear、last 易错句：The accident was happened yesterday.（错） 正确句：The accident happened yesterday.（对） 感官、使役动词被动还原to 主动：make/let/have sb do（省略to） 被动：sb be made to do（必须还原to） 例句：He was made to finish the work on time. 译文：他被要求按时完成这项工作。 主动表被动特殊句型 部分动词主动形式表被动含义。 常用词：sell、wash、write、read、look 例句：This kind of book sells well. 译文：这种书很畅销（不用is sold）。 被动语态否定、疑问句式 否定：主语 + be not + done 疑问：Be + 主语 + done ? 例句：Is the tool made of metal? 译文：这个工具是金属制成的吗？ 时态变化全部体现在be动词上。 题型一 语态判断 判断句子为主动语态/被动语态 1.
