1 一、 英语动词有两种语态： 主动语态 (the Active Voice) 被动语态 (the Passive Voice) A. 当主语为动作的执行者时，谓语的形式为主动语态。 Many people speak English. B. 当主语为动作的承受者时，谓语要用被动语态 English is spoken by many people. 注： 及物动词 (后面能接宾语的动词) 才有被动语态 2 二、被动语态的基本结构: be + V-PP(动词的过去分词) be动词可以随 时态、人称和数的变化而变化。 3 1. 一般现在时： am / is / are + 及物动词的过去分词 2. 一般过去时： was / were + 及物动词的过去分词 3. 现在/过去完成时： has / have/had + been + 及物动词的 过去分词 4. 一般将来时： will+ be + 及物动词的过去分词 5. 含有情态动词：情态动词+ be + 及物动词的过去分词 6. 现在进行时： am / is / are + being + 及物动词的过去分 词 歌诀：被动语态be字变，过去分词跟后面 4 规则动词过去分词的构成 (过去分词和过去式的变化规则是一样的 ) 1:一般在动词末尾加-ed. look—looked open—opened play—played borrow—borrowed 2:以e结尾的动词加-d. use—used live—lived dance—danced recite—recited 3:以 “辅音字母+y”结尾的动词,先变y为i 再加-ed. study—studied carry—carried try—tried worry—worried 4:末尾只有一个辅音的重读闭音节,先双写该辅音字 母,再加-ed.( fix的过去式和过去分词x不双写，为fixed. ) stop—stopped plan—planned 5 一、 AAA型(动词原形、过去式、过去分词 同形) 二、 AAB型(动词原形与过去式同形) 三、 ABA型(动词原形与过去分词同形) 四、 ABB型(过去式与过去分词同形) 五、 ABC型(动词原形、过去式与过去分词 三者不同形) 中考英语不规则动词过去式、过去分词 归类表 6 cost (花费) cost cost cut (割) cut cut hit (打;碰撞) hit hit hurt (伤害) hurt hurt let (让) let let put (放) put put read (读) read／red/ read ／red/ set (放置 ) set set shut (关闭) shut shut 一、 AAA型(动词原形、过去式、过去分词同形) 7 二、 AAB型(动词原形与过去式同形) beat (跳动) beat beaten 三、 ABA型(动词原形与过去分词同形) become (变成) became become come (来) came come run (跑) ran run 8 get (得到) got got hang (吊死) hanged hanged hang (悬挂) hung hung hold (抓住) held held sit (坐) sat sat babysit(临时照顾) babysat babysat win (赢) won won 四、 ABB型(过去式与过去分词同形) 9 meet (遇见) met keep (保持) kept sleep (睡) slept sweep (扫) swept feel (感觉) felt leave (离开) left build (建设) built send (传送) sent spend (花费) spent lose (丢失) lost met kept slept swept felt left built sent sp
