被动语态 (Passive Voice) 全解析
一、语态概述
英语动词有两种语态,即主动语态 (Active Voice) 与被动语态 (Passive Voice)。主动语态强调主语是动作的执行者,比如 “I clean the room.(我打扫房间。)”,这里 “I” 是动作 “clean” 的执行者;而被动语态则强调主语是动作的承受者,例如 “The room is cleaned by me.(房间被我打扫。)”,此时 “The room” 是动作 “clean” 的承受者。
二、被动语态的构成
被动语态的基本构成是:be 动词 + 过去分词 + by + 动作执行者。其中,be 动词有人称、数和时态的变化,它要与句子的主语在人称和数上保持一致,同时根据不同的时态进行相应变形。
三、被动语态的时态

示例
一般现在时的被动语态
am/is/are + 过去分词
The classroom is cleaned every day.(教室每天都被打扫。)
一般过去时的被动语态
was/were + 过去分词
The book was written by him last year.(这本书是他去年写的。)
现在进行时的被动语态
am/is/are + being + 过去分词
The bridge is being built now.(那座桥现在正在被建造。)
过去进行时的被动语态
was/were + being + 过去分词
The house was being painted when I passed by.(我路过的时候,那栋房子正在被粉刷。)
现在完成时的被动语态
have/has + been + 过去分词
The work has been finished.(工作已经完成了。)
过去完成时的被动语态
had + been + 过去分词
The report had been handed in before the deadline.(报告在截止日期前就已经交上去了。)
含情态动词的被动语态
情态动词 + be + 过去分词
The rules must be obeyed.(必须遵守规则。)
一般将来时的被动语态
will/shall + be + 过去分词
A new hospital will be built in our town.(我们镇上将会建一家新医院。)
过去将来时的被动语态
would/should + be + 过去分词
He said that the task would be completed soon.(他说任务很快就会完成。)
四、特殊的被动语态
含有双宾语的被动语态:含有双宾语的主动句变被动句时,若指物的间接宾语变为被动语态的主语,间接宾语前要加介词 to 或 for 等。
例如,“He gave me a book.(他给了我一本书。)” 变为被动语态可以是 “A book was given to me by him.(一本书被他给了我。)” 或者 “I was given a book by him.(我被他给了一本书。)”。 当直接宾语变成被动语态的主语时,用 to 侧重动作的方向,用 for 侧重动作的受益者。
复合宾语的被动语态:若主动语态中的宾补是省略 to 的动词不定式,变为被动语态时需把 to 补上。例如,“We saw him play football.(我们看见他踢足球。)” 变为被动语态是 “He was seen to play football.(他被看见踢足球。)”。
五、被动语态的用法
· 不知道或没有必要指出动作的执行者时:
例如,“The window was broken.(窗户被打破了。)”,
此时重点在于窗户的状态是被打破,而不关心是谁打破的。
· 强调动作的承受者,而不是执行者时:比如,“The letter was written carefully.(这封信写得很仔细。)”,强调信是被仔细写的,突出信的完成状态。
· 当动作的执行者不是人,而是无生命的事物时:像 “The cake is made by the machine.(蛋糕是由机器制作的。)”,这里强调蛋糕是机器制作的结果。
六、注意事项
· 部分动词不用被动语态:happen, belong to, have, cost, last, own, stay 等一般不用被动语态。
例如,“The story happened last night.(故事发生在昨晚。)”,不能说 “The story was happened last night.”;“This book belongs to me.(这本书属于我。)”,不能说 “This book is belonged to me.”。
· 主动形式表被动意义的情况:taste, sound, prove, feel, look, smell 等系动词常用主动形式表示被动意义。
例如,“The food tastes delicious.(食物尝起来很美味。)”;read, sell, wash, write 等动词用来说明主语的性质特征时,也常用主动形式表示被动意义。比如,“This kind of book sells well.(这种书很畅销。)”“The pen writes smoothly.(这支笔书写流畅。)”。
