The dog has died.- The dog has been dead since last week. have has been to + 地点去过某地已经回来have has gone to + 地点去了某地没有回来have been in + 地点始终呆在某地没有离开过Unit 9 被动语态.被动语态的构成形式 be+Vt.p.p. 一.语态是英语动词的一种形式,是用于表示主语和谓语之间的关系;英语语态分为主动语态 active voice和被动语态 passive voice两种;主动语态是表示主语是动作的执行者;被动语态是表示主语是动作的承担者;二被动语态的基本时态变化如:1Yesterday I parked my car outside the school. 2A sound of piano is heard in the hall. 在被动语态的句子中,谓语部分的结构是be+Vtp.p. 及物动词过去分词;其中be 是变量,随时态的变化而变化;动词的过去分词是常量,永久不发生变化;当然,这只是指谓语部分而言; be 动词作为一个独立的谓语动词有自己现在分词being和过去分词 been;那么,下面我们来看看be 在各种时态中的变化形式:被动语态通常为八种时态的被动形式;以do为例,各种时态的被动语态形式为:1am/is/are+done过去分词 一般现在时 2has/have been done 现在完成时 3am/is/are being done 现在进行时 4was/were done 一般过去时 5had been done 过去完成时 6was/were being done 过去进行时 7shall/will be done 一般将来时 8should/would be done 过去将来时 .一般来说,在我们日常生活中,能用主动语态的时候就尽量不去用被动语态;只有在下列情形中我们才用被动语态:名师归纳总结 英语里被动语态的使用好像比汉语要广泛;英语的被动语态常用在以下的场合:1当我第 3 页,共 5 页- - - - - - -精选学习资料 - - - - - - - - - 学习好资料 欢迎下载们不知道动作的执行者的时候,如:away. 2.My car has been moved. 1.Look.There s nothing here.Everything has been taken 2当我们不必提出动作的执行者的时候,如:I was born in 1960. 3当我们强调或侧重动作的承担者的时候,如:.特别的被动结构She is liked by everybody. 1带情态动词的被动结构:它的固定句式为“ 情态动词 +be+过去分词” ;也有个别带 to的情态动词例外, 如:ought to 和 have to,它们的被动结构就只能在不定式中;例如:The debt must be paid off before next month 那笔债务必需在下个月前付清;2带有两个宾语的主动语态变成被动语态将这种主动态的句子完成被动态的句子,可选两个宾语中的任何一个作为被动态句子的主语,而将另一个宾语作为“ 保留宾语” 写入被动态的句中;但有一点要说明,那就是,如果你选直接宾语作“ 主语” ,有时要在被动态句子的“ 保留宾语” 前加上合格的介词;由于这些动词常有两种句式,即:我们可以说give sb.sth.,send sb.sth.,buy sb.sth;我们也可以说give sth to sb,send sth to sb buy sth for sb;请看下面两种情形的对比:She sent me a novel on my birthday. I was sent a novel on my birthday. A novel was sent to me on my birthday. 3关于带有复合宾语的主动态变成被动态假如将带有复合宾语既:宾语 +宾语补足语 的主动语态的句子变成被动语态的句子,我们只能挑选原先句子的宾语作被动语态句子的主语;成被动语态句子的“ 主语补足语” 了;The story made us laugh.宾语补足语 而这时, 原句里的宾语补足语现在就变We were made to laugh by the story. 主语补足语 4在使役动词 have,make,get 以及感官动词 see,watch,notice,hear,feel,observe等后面不定式作宾语补语时,在主动结构中不定式 to 要省略, 但变为被动结构时,要加 to;Someone saw a stranger walk into the building. A stranger was seen to walk into the building. 5有些相当于及物动词的动词词组,如“ 动词+介词” ,“ 动词 +副词” 等,也可以用于被动结构,但要把它们看作一个整体,不能分开;其中的介词或副词也不能省略;例 The meeting is to be put off till Friday. 6非谓语动词的被动语态;v+ing 形式及不定式to do 也有被动语态一般时态和完成时态;例 ,I don t like being laughed at in the public.There are two more trees to be planted. Unit 10 过去完成时一.过去完成时由“ 助动词 had+过去分词” 构成;二.过去完成时表示在过去某一时间或动作之前已经发生或完成了的动作;它表示动作发生的时间是“ 过去的过去” ;He said he had been to Hainan before.他说他以前去过海南;三.过去完成时“ 过去的过去” 的表现形式;1.可以用 by,before 等构成的短语来表示;eg:By the end of the match ,they had kicked two goals. 直到竞赛终止的时候为止,他们踢进了两个球;We had reached the station before ten o clock. 名师归纳总结 - - - - - - -第 4 页,共 5 页精选学习资料 - - - - - - - - - 学习好资料 欢迎下载在十点钟以前,我们已经到达了车站;2.也可以用 when, before,after 等引导的从句来表示;eg:When I got there,you had already started playing the match. 当我到那里时,你们已经开头竞赛了;Wang Lin had mended the radio before his brother returned. 王林在他弟弟回来以前就已经把收音机修好了;3.通过宾语从句或通过上下文示意;eg:He remembered that he had seen the book.他记得他曾读过这本书;He said he had handed in his composition. 他说他已经把作文上交了;We did as he had told us.我们按他说的做;名师归纳总结 - - - - - - -第 5 页,共 5 页
