/ 让学习更有效 新课备课备考 | 英语学科 2026年春牛津译林版九年级英语下册核心语法精讲精练 Unit 1 Asia 核心语法：一般现在时的被动语态 一、核心概念 1. 被动语态再认识 主动语态：主语执行动作 例：Millions of people speak English.（数百万人说英语。） 被动语态：主语承受动作 例：English is spoken by millions of people.（英语被数百万人说。） 2. 一般现在时的被动语态 表示经常性、习惯性发生的动作，且主语是动作的承受者。 二、结构公式 1、基本结构： am/is/are + 过去分词 (p.p.) 2、具体构成： 主语人称 助动词 过去分词 例句 I am p.p. I am taught English by Mr. Li. He/She/It is p.p. This computer is used every day. We/You/They are p.p. These books are read by many students. 3、否定形式： am/is/are + not + 过去分词 例：Rice is not grown in the north. 缩写：isn't, aren't 4、疑问形式： Am/Is/Are + 主语 + 过去分词 + 例：Are cars made in this factory 三、使用情景 1. 描述客观事实或普遍真理 The sun is risen in the east.（太阳从东方升起。） Water is changed into ice at 0℃.（水在0度时变成冰。） 2. 表示经常性、习惯性的动作 Letters are collected at 4 p.m. every day.（信件每天下午4点收取。） This room is cleaned twice a week.（这个房间每周打扫两次。） 3. 说明物品的用途或功能 Knives are used for cutting.（刀用来切割。） This machine is used to make paper.（这台机器用来造纸。） 4. 科技说明、新闻报道、规章制度 Smoking is not allowed here.（此处禁止吸烟。） English is spoken as a second language in many countries. 四、句法转换 主动变被动三步法： 1、找宾语：主动句的宾语 → 被动句的主语 2、变谓语：动词 → am/is/are + p.p. 3、加by短语：动作执行者前加by（可省略） 转换对比表： 主动句 被动句 People grow rice in the south. Rice is grown in the south (by people). My mother washes clothes every day. Clothes are washed by my mother every day. Do they speak French in Canada Is French spoken in Canada 五、特殊句型处理 1. 含情态动词的被动语态 情态动词 + be + 过去分词 主动：We must protect the environment. 被动：The environment must be protected. 2. 双宾语动词的被动语态 主动：The teacher gives us homework. 被动1：We are given homework by the teacher. 被动2：Homework is given to us by the teacher. 3. 短语动词的被动语态 保持短语完整性，介词/副词不能丢 主动：They often laugh at him. 被动：He is often laughed at. 主动：We should take care of the old. 被动：The old should be taken care of. 六、常见错误提醒 1、be动词遗漏 English spoken all over the world. English is spoken all over the world. 2、用错be动词形式 Rice are grown in the south. Rice is grown in the south. 3、忘记过去分词 The floor is clean by him every day. The floor is cleaned by him every day. 4、by短语使用不当 The letter is written by me yesterday. The letter was written by me yesterday.（时态错误） 1．Monkey King is brave and humorous.
