2026-2027学年九年级英语上册语法精讲精练(人教版新教材) Unit5 Power of Ideas 核心语法:被动语态(一般现在时、一般过去时被动语态) 语法精讲 一、主动语态 vs 被动语态 概念 主动语态:主语是动作的发出者(执行者) 结构:主语(执行者)+ 谓语动词 + 宾语(承受者) 例:We clean the classroom. 我们打扫教室。 we 打扫这个动作的执行者 被动语态:主语是动作的承受者(被……) 把原句宾语提前作主语,强调承受者,或者不知道、不想说出动作执行者。 例:The classroom is cleaned (by us). 教室被(我们)打扫。 the classroom 打扫动作的承受者 只有及物动词(后面能带宾语)才有被动语态! 不及物动词(happen, arrive, appear 等)无被动 二、被动语态通用结构 be + 动词过去分词 (done) be 动词用来体现:时态、人称、单复数; 过去分词永远不变。 三、两大核心时态精讲 1. 一般现在时被动语态 肯定句:am / is / are + done I am done 单数主语 / 不可数名词 is done you / 复数主语 are done 否定句:am / is / are + not + done 一般疑问句:Am / Is / Are + 主语 + done …? 例句: 主动:People grow rice in the south. 被动:Rice is grown in the south. 水稻在南方被种植。 主动:We clean our classroom every day. 被动:Our classroom is cleaned every day. 主动:They make these bikes in China. 被动:These bikes are made in China. 否定:The room is not cleaned every day. 疑问:Is English spoken here? 2. 一般过去时被动语态 肯定句:was / were + done 单数主语 / 不可数名词 was done you / 复数主语 were done 否定句:was / were + not + done 一般疑问句:Was / Were + 主语 + done …? 例句: 主动:He built the house last year. 被动:The house was built last year. 这栋房子是去年建成的。 主动:Somebody stole my bike yesterday. 被动:My bike was stolen yesterday. 主动:They planted many trees last spring. 被动:Many trees were planted last spring. 否定:The letters were not sent yesterday. 疑问:Were the windows closed just now? 四、by 短语用法(重点) 被动句中,如果需要写出动作执行者,用 by + 动作发出者 The letter was written by my father. 这封信是我爸爸写的。 日常经常省略 by 短语:不知道执行者、不需要强调执行者 Lots of toys are made in this factory.(不用写 by workers) 五、主动变被动 四步万能方法 1.把主动句宾语提到句首,作被动句主语 2.判断时态:一般现在时 am/is/are;一般过去时 was/were 3.谓语动词改为 be + 过去分词 4.原主语前加 by,放句子末尾,可省略 示例: 主动:She washes the dishes every day. ①宾语 the dishes 提前 ②一般现在时,复数 are ③wash washed The dishes are washed (by her) every day. 六、高频必考:不规则动词过去分词(必背) make — made build — built write — written speak — spoken steal — stolen see — seen break — broken buy — bought 规则变化:动词 + ed(clean-cleaned;plant-planted) 七、易错考点 ️ 1.不及物动词无被动 happen, take place, appear, arrive An accident was happened. An accident happened. 2.感官动词、使役动词主动不带 to,被动必须加 to(拓展考点) 主动:We make him work. 被动:He is made to work. 3.不要混淆时态 The bridge was built in 2010.(一般过去时被动语态) The bridge is built in 2010. 八、一般现在时被动 VS 一般过去时被动对比 类型 结构 时间标志词 一般现在被动 am/is/are + done every day, usually, often, always 一般过去被动 was/were + done yesterday, last…, …ago, just now 语法精练 一、单项选择题 1.Many useful things _ every year.
