高中英语知识点归纳被动语态的特殊情况与应用
高中英语知识点归纳被动语态的特殊情况与应用被动语态在英语中是一个非常常见且重要的语法点。
它经常用来描述一个动作的接受者或者受害者，而不是执行者。
在被动语态的基本情况下，我们需要使用"be + 过去分词"的形式构建句子。
然而，在某些情况下，被动语态会存在一些特殊的应用以及使用上的注意事项。
本文将对这些特殊情况进行归纳总结，以及在学习被动语态时需要特别注意的内容。
一、特殊情况1. 直接宾语变主语在被动语态中，直接宾语常常会转变为句子的主语。
通常，我们将及物动词后的宾语作为主语，而将原主语置于介词"by"之后。
例如: Active: They make cars in this factory.Passive: Cars are made in this factory (by them).在以上例子中，"cars"从主动语态中变为了被动语态的主语，而"they"则放在了介词"by"之后。
2. 间接宾语在有间接宾语的情况下，我们通常将间接宾语置于介词"to"之后。
例如:Active: They gave me a book.Passive: I was given a book (by them).在这个例子中，"me"从直接宾语变为了被动语态的主语，并放在了介词"by"之后。
3. 及物动词与介词短语有一些及物动词后面跟着介词短语，当它们转换为被动语态时，介词会移到句子的末尾。
例如:Active: He took care of his brother.Passive: His brother was taken care of (by him).在这个例子中，"of his brother"变为了被动语态中的介词短语，并放在了句子末尾。
被动语态中的特殊情况
被动语态中的特殊情况被动语态是英语语法中的一个重要部分，它用来强调动作的接受者而不是执行者。
在大部分情况下，我们可以很容易地转换主动语态为被动语态，只需将动作的执行者放在by后作为被动语态的主语，而原主语则变成被动语态的宾语。
然而，有些情况下，被动语态的转换并不十分直观，本文将讨论被动语态中的几种特殊情况。
一、动词不及物在被动语态中，大部分情况下我们需要一个及物动词（transitive verb）才能正确转换为被动语态。
及物动词是指需要一个宾语才能成立的动词。
然而，有些动词是不及物动词（intransitive verb），它们无法直接转换为被动语态。
例如：主动语态：He sleeps eight hours every night.被动语态：（不可转换）在这个例子中，动词sleep是不及物动词，因此无法转换为被动语态。
在这种情况下，我们需要使用其他方式来传达类似的含义。
二、形容词和副词在一些情况下，我们可以使用形容词或副词来表达被动语态的含义，而无需使用被动语态的结构。
例如：主动语态：The book is interesting.被动语态：The book is interested in.在这个例子中，我们使用形容词interested来替代被动语态的结构，并传达了同样的含义。
同时，有些副词也可以用来表示被动语态的意思。
例如，actively可以用来表示被动地接受动作，而passively则可以用来表示主动地执行动作。
三、某些动词的特殊用法有一些动词在被动语态中有着特殊的用法。
1. get和haveget和have可以与过去分词形式结合，并表示被动的含义。
例如：主动语态：She gets her car washed every week.被动语态：Her car gets washed every week.主动语态：He had his house painted last year.被动语态：His house was painted last year.2. keep和leavekeep和leave可以与过去分词形式结合，并表示保持或保留的被动含义。
英语被动语态的用法
被动语态使用中的特殊情况及注意点一. 被动句的使用场合一个句子，到底使用主动语态还是被动语态，这和说话人的意图紧密相关。
以下场合通常使用被动语态。
A）说话人强调的是动作的承受者，或者是事件本身。
而说话者认为不必或不想提及动作的发出者。
如：The bridge was built in 1929.Hundreds of passengers were killed in the accident.Eight hours every day for sleep must be guaranteed.(确保)B）由于不知道动作的发出者是谁。
如：This book was published in the 16th century.They were told not to enter the house.C) 为了强调动作的发出者，若用主动态，让它出现在主语位置上不如用带by—词组的被动态突出。
如：Who invented the telephone?It was invented by Bell(贝儿)How was the glass broken?It was broken by Tom.D) 有时为了避免中途变换主语，或是使上下文紧密衔接而采用被动语态。
如：John beat Tom and was punished by the teacher.（避免变换主语）He visited China's northeastern provinces in 1935. Those provinces were controlled by the Japanese invaders.(使上下文联系紧密)二．不能用于被动语态的情况1）某些表示“静态”的及物动词（表示状态而不是动作，而且常常是不可用于进行时态的动词）如have，fit，suit，hold（容纳），cost，suffer，last（持续）等不能用于被动语态。
英语被动语态
英语被动语态被动语态，即不知道动作执行者或强调动作承受者的一种语态。
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。
被动语态表示主语是动作的承受者，即行为动作的对象。
主动语态变为被动的几个特殊情况① 有些动词在主动结构中，后面接不带to的不定式，但如果改为被动，则需把省略的to加上，这类动词有 [let, make, have,help]和感官动词[feel,see,hear,watch,look at,listen to]，如：The boss made my grandfather work 10hours a day.改成My grandfather was made to work for 10 hours a day.② 含有宾语从句的主动结构变为被动，通常用it作为被动结构的先行主语，从句放在句子后面/也可采用另一种形式，这类动词有：know, say, believe, find, think, report等③ 不是所有的主动句都可以变换成被动句，更不是所有的被动句都可以自由变换成主动句。
虽然语法原则上允许主动和被动句的互相转换，但有的句子转换后会变成不通顺或不地道的英语句子。
因此，在某些题目里，这也成为判断应该用主动还是用被动的依据。
例：At 5:05 p.m. on Saturday 19th July , there was an accident at the junction of the Main Street and Panda Road when a boy was knocked down off his bicycle by a delivery van. The boy was sent to St. Maria Hospital where he was treated for shock and a broken arm.在这段文章里，a boy was knocked down off his bicycle by a delivery van这句被动句强调出读到文章的人最关心的事故的受害者。
高中英语知识点归纳被动语态中的特殊情况和结构
高中英语知识点归纳被动语态中的特殊情况和结构被动语态是英语语法中的一个重要部分，也是学习英语的学生常常会遇到的难点之一。
在一般情况下，被动语态的构成较为简单，即“被动助动词（be动词的各种形式）+过去分词”。
然而，在某些特殊情况下，被动语态的使用存在一些特殊的结构和用法。
本文将对高中英语被动语态中的特殊情况和结构进行归纳总结。
一、不及物动词的被动语态通常情况下，不及物动词是没有被动形式的，因为它们本身就不具备被动的意义。
但是，在某些情况下，我们需要使用被动语态来表达被动的含义。
这时，需要借助于转换结构，即将不及物动词转化为及物动词，然后再使用被动语态。
示例：1. 主动语态：The tree grows rapidly.（这棵树生长很快。
）转换为被动语态：The tree is grown rapidly.（这棵树生长得很快。
）2. 主动语态：They sleep for eight hours every day.（他们每天睡八个小时。
）转换为被动语态：They are slept for eight hours every day.（他们每天被睡八个小时。
）二、双宾语的被动语态某些及物动词可以接受两个宾语，一个是直接宾语，一个是间接宾语。
当双宾语的句子转换为被动语态时，可以根据需要选择保留其中一个宾语或保留两个宾语。
示例：1. 主动语态：He gave me a gift.（他给了我一件礼物。
）转换为被动语态（保留直接宾语）：I was given a gift by him.（我被他给了一件礼物。
）2. 主动语态：She bought her sister a book.（她给她姐姐买了一本书。
）转换为被动语态（保留间接宾语）：Her sister was bought a book by her.（她姐姐被她买了一本书。
）三、感官动词的被动语态感官动词（如see、watch、hear、notice等）表示看、听等感官动作的动词，一般不用于进行被动语态的转换，而是使用不带被动意义的形式，即使用主动形式作为被动语态。
各种时态的被动语态
各种时态的被动语态一、八大时态的被动语态的构成：1．一般现在时的被动语态构成：（am/is/are +done）如：I am asked to study hard. 我被请求努力学习。

被动语态详解一、被动语态的用法：1、不知道或没有必要指出谁是动作的执行者时。
The bridge was built last year.这座桥是去年建造的。

被动语态的特殊用法
被动语态的特殊用法我们刚刚学习了被动语态的构成与一些基本用法,下面就一起来瞧瞧被动语态的一些特殊用法。
一、一些特殊动词的被动语态1、跟复合宾语的动词的被动语态感官动词或使役动词的主动语态后跟不带to不定式作宾语补足语,但变为被动语态时,须转为带to不定式。
如:I saw a bag drop from the bus、→A bag was seen to drop from the bus、Mother made her baby sleep in her arms、→The baby was made to sleep in her mother’s arms、2、跟双宾语的动词的被动语态直接宾语与间接宾语都可作被动语态的主语。
如:Mr、Smith gave us a lecture、→We were given a lecture by Mr、Smith、或A lecture was given by Mr、Smith、当句中含有return, write, find, buy等动词时,常把直接宾语转为被动语态的主语,同时要注意介词的搭配。
如:I returned him the book、→The book was returned to him、(注意用to)He wrote me a short note、→A short note was written to me、(注意用to)He found me an umbrella、→An umbrella was found for me、(注意用for)I bought her some flowers、→Some flowers were bought for her、(注意用for)3、短语动词的被动语态变成被动语态时,短语动词应当瞧作一个整体,其中的介词或副词不能丢掉。
如:We can’t look down upon anybody、→Anybody can’t be looked down upon、The doorkeeper turns off the lights at 11 pm every day、→The lights are turned off at 11 pm by the doorkeeper every day、The nurse is taking care of the sick man、→The sick man is being taken care of by the nurse、二、被动语态的几种特殊形式1、当break, wash, sell, burn, read, clean, run, ride, wear, write等动词有状语修饰时,用主动形式表示被动意义。
被动语态的特殊结构形式
被动语态的特殊结构形式1)带情态动词的被动结构。
其形式为：情态动词+be+过去分词。
例:The baby should be taken good care of by the baby-sitter.2) 有些动词可以有两个宾语，在用于被动结构时，可以把主动结构中的一个宾语变为主语，另一宾语仍然保留在谓语后面。
通常变为主语的是间接宾语。
例:His mother gave him a present for his birthday. 可改为He was given a present by his mother for his birthday.3) 当“动词+宾语+宾语补足语”结构变为被动语态时，将宾语变为被动结构中的主语，其余不动。
例:Someone caught the boy smoking a cigarette. 可改为The boy was caught smoking a cigarette.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。
例:Someone saw a stranger walk into the building. 可改为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.。
