中考语法语态精讲 考点一 被动语态的应用 语态是动词的一种形式,表示主语和谓语的关系。当主语是动作的执行者时用主动语态(某人做某事);当主语是动作的承受者时,用被动语态(某事被某人做)。一、各种时态的被动语态 被动语态由“主语+be+及物动词的过去分词”构成,助动词有时态、人称和数的变化。结构例句一般现在时:主语+am/is/are+过去分词The classroom is cleaned every day.教室每天都打扫。一般过去时:主语+was/were+过去分词Our school was built in 1998.我们的学校在1998年建造。一般将来时:主语+shall/will+be+过去分词The sports meeting will be held tomorrow. 运动会明天举行。现在进行时:主语+am/is/are +being+过去分词The car is being repaired.这辆汽车正在修理中。过去进行时:主语+was/were +being+过去分词The machine was being painted then. 那时那台机器正在上油漆。现在完成时:主语+has/have +been+过去分词The bank has been built.银行已经建成了。过去完成时:主语+had +been+过去分词I had been invited to visit America before I came here. 在来这儿之前我已经被邀请访问美国了。过去将来时:主语+should/would+be+过去分词Ann told me she would be sent to America. 安告诉我她将被派往美国。含有情态动词的被动语态:主语+情态动词+be+过去分词The bike cant be put here.这辆自行车不能被放在这里。 二、主动语态变被动语态的方法第一步:先确定主动句的主、谓、宾,找出其中的谓语动词。第二步:把主动句中谓语动词后面的宾语变为被动句的主语,若宾语是人称代词,应把宾格变为主格。第三步:把主动句中的谓语动词变为“助动词be + 及物动词的过去分词”,但时态不能改变。第四步:把主动句中谓语动词前面的主语变为被动句中介词by的宾语(没必要说出动作的执行者时可省略),若主语是人称代词时,应把主格变为宾格。 考点二 被动语态的几种特殊形式1. 主动句中感官动词see/hear/watch/feel等和使役动词make/let/have等后跟省略to的动词不定式,变为被动语态时应加上不定式符号to。例如:We saw an alien get out of the UFO. An alien was seen to get out of the UFO.【温馨提示】后接现在分词作宾语补足语的动词变为被动语态时,宾补部分不变。对比:We heard Jim playing the guitar in his room. Jim was heard playing the guitar in his room.2. 谓语动词后接双宾语(直接宾语和间接宾语)时,(1)把间接宾语变为主语,直接宾语不变。例如:He gave me a new book. 间接宾语 直接宾语I was given a new book by him. (2)把直接宾语变主语,间接宾语不变。例如:He gave me a new book. 间接宾语 直接宾语A new book was given to me by him. 3. 句中谓语是动词短语时,变为被动语态时要注意其完整性。Jack turned on the TV just now.The TV was turned on by Jack just now.4. 带有复合宾语的动词变为被动语态时,只须把宾语变为被动语态的主语,而宾语补足语仍保留在原处,作主语补足语。例如:Our teacher told us to clean the classroom at once.We were told to clean the classroom at once by our teacher.5. 主动表被动(1) feel, look, sound, smell, taste等系动词的主动语态表示被动含义。例如:The dishes smell so delicious.菜闻起来真香。Your idea sounds better.你的主意听起来更好。(2)有些动词,如sell, cut, drive, wash, clean, write, open, lock等,作为不及物动词时可以用主动语态表示被动含义。例如:Books of Harry Potter sell well.哈利波特系列的书很畅销。My pen writes smoothly.我的钢笔写起字来很流畅。 (3) sth. need/ want/ require doing相当于sth. need/ want/ require to be done (不定式的被动结构)。例如:Your room needs cleaning. = Your room needs to be cleaned. 你的房间需要打扫了。(4)be worth doing(值得做) 中的doing表示被动含义。The movie is worth watching by everyone.这部电影值得所有人看一看。6. 不用被动语态的情况(1)系动词、不及物动词或某些动词短语没有被动语态。 例如:come true; fall asleep; keep quiet; take place等;(2)主动句的宾语是不定式或doing时不能用作被动语态的主语;(3)反身代词或each other不能作被动语态的主语。7. 被动语态与系表结构的区别“be + p. p. ”表示动作时是被动语态;“be + p. p. ”表示主语所处的状态时是系表结构。(1)含有“by + 宾语”结构强调动作执行者,此时为被动语态。例如:The window is broken. 窗户坏了。(系表结构)The window is broken by me. 窗户是我打破的。(被动语态)(2)句中有地点、频率或时间状语时,一般是被动语态。例如: The door was closed. 门是关着的。(系表结构) The door was closed at 9: 00. 九点钟关的门。(被动语态)(3)系表结构中常用介词搭配,被动语态中没有介词搭配。例如:Were worried about the boy.我们担心那个男孩。(4)系表结构的过去分词可以被副词修饰。例如: Im really surprised at the news.我对这个消息真的感到很惊讶。(5)系表结构通常只有一般现在时和一般过去时,而被动语态可用于多种时态。
