1 / 42 被动【概念引入】 一、含有被动语态的名言欣赏 Life is measured by thought and action, not by time. 衡量生命的尺度是思想和行动，而不是时间长短。 Men are known by his companions. 观其友而知其人。 Rome was not built in a day. 罗马不是一天建成的。 A friend without fault will never be found. 没有缺点的朋友永不可得。 二、被动语态的概念 英语的语态是通过动词形式的变化表现出来的。英语中有两种语态：主动语态和被动语态。 主动语态表示主语是动作的执行者。 Many people speak Chinese.许多人说汉语。 谓语speak的动作是由主语many people来执行的。 被动语态表示主语是动作的承受者，即行为动作的对象。 Chinese is spoken by many people.汉语被许多人说。 主语Chinese是动词speak的承受者。 【用法讲解】 2 / 42 一、被动语态结构【高清课堂：Passive Voice与时态】 一般现在时：am / is / are +及物动词的过去分词 You are wanted on the phone.有你的电话。 一般过去时：was / were +及物动词的过去分词 China was liberated in 1949. 1949年中国解放。 一般将来时：will / shall be +及物动词的过去分词 The problem will be discussed tomorrow. 明天将对这个问题进行讨论。现在完成时：have / has been +及物动词的过去分词 Not a book in the library has been taken away.图书馆里没有一本书被人拿走。 现在进行时：am / is / are being +及物动词的过去分词 My bike is being repaired.我的自行车正在修理。 过去完成时：had been +及物动词的过去分词 The book had been borrowed when I got to the library. 我到了图书馆时,xx已经借出去了。 二、主动语态与被动语态的转换 1）把主动语态的宾语变为被动语态的主语。 2）把谓语变为被动结构（be＋过去分词） 注意：根据被动语态句子里的主语的人称和数，以及原来主动语态句子中动词的时态来决定be的形式。 3）把主动语态中的主语放在介词by之后作宾语，将主格改为宾格。 3 / 42 All the people laughed at him.所有人都嘲笑他。 →He was laughed at by all people.
