2. 有些动词用主动形式表示被动意义。 如: write, sell, ride.....
This pen writes well.
This new book sells well.
3. 感官动词或使役动词使用省略to的动词不定式,主动语态中不带“to”,但变为被动语态时,须加上“to”。
例:make somebody do something→somebody+ be +made to do something
see somebody do something→somebody +be +seen to do something
A girl saw my wallet drop when she passed by.→My wallet was seen to drop by a girl when she passed by.
The boss made the little boy do heavy work.→The little boy was made to do heavy work by the boss.
4. 如果是接双宾语的动词改为被动语态时,直接宾语(物)作主语,那么动词后要用介词,这个介词是由与其搭配的动词决定。
He gave me a book.→A book was given to me by him.
He showed me a ticket.→A ticket was shown to me by him.
My father bought me a new bike. →A new bike was bought for me by my father.
5. 一些动词短语用于被动语态时,动词短语应当看作一个整体,而不能丢掉其中的介词或副词。
We can’t laugh at him. →He can’t be laughed at by us.
He listens to the radio every day. →The radio is listened to by him every day.
The nurse is taking care of the sick man. →The sick man is being taken care of by the nurse.

  • 主动句变为被动句所遵循的4个步骤:
    ①把原主动句中的宾语变为被动句的主语
    ②把动词变为被动形式即be +过去分词,并注意其人称和数随主语的变化,而动词的时态则保持不变。
    ③原主动句的主语如需要则放在by后面以它的宾格形式出现(注代词的宾格),如不需要则可省略。
    ④其它的成分(定语、状语)不变。

    不用于被动语态的情形:
    ①不及物动词没有被动语态
    这类动词有take place, happen, come about, break out, appear, disappear, last,  arise等。
    例如:A fire broke out during the night.
    ②某些静态动词不用于被动语态
    这类动词有have, lack, fit, hold, suit, resemble等。 
    例如:My shoes do not fit me.
    ③宾语为相互代词和反身代词时不用于被动语态
    例如:We should help each other.

    关于主动形式表示被动意义:
    ①系动词(如look, sound, smell, feel, taste, prove等)要用主动表被动,因为系动词为不及物动词,它们没有被动语态形式。
    例如:The building looks very beautiful.
    ②当open, close, shut, lock, move, read, wash, clean, cook, cut, wear, carry 等用作不及物动词且表示主语的某种属性时,通常用主动形式表示被动意义。
    例如:The book sells well.
    ③有的动词本身含有被动意味,通常用主动形式来表示被动含义。
    例如:Her eyes filled with tears.
    ④不定式to blame, to let用作表语时,通常要用主动表被动。
    例如:Who is to blame?
    ⑤某些“be+形容词+to do”结构中的不定式通常要用主动形式表示被动意义。
    例如:The book is difficult to understand.
    ⑥不定式用于某些动词(如have, have got, get, want, need等)的宾语后作定语时,如果不定式的逻辑主语就是句子的主语,通常用主动形式表示被动意义。
    例如:Do you have time to help us?
    ⑦在too...to do sth.和...enough to do sth. 这两个结构中,若主语与其后不定式为to do sth.被动关系,则该不定式通常用主动形式表示被动意义(有时也可直接用 被动式)。
    例如:The writing is too faint to read.
    ⑧be worth后的动名词要用主动表被动。
    例如:This movie is worth seeing.
    ⑨在need, want, require等少数表示“需要”的动词后的动名词用主动形式表示被动意义。
    例如:The house needs cleaning.

    表示“据说”的三类被动句型:
    ①It is said that...句式
    例如:It is said that thirteen is an unlucky number.
    ②There is said that...句式 
    例如:There is said to be plenty of oil off our coast.
    ③sb./sth.is said that...句式
    例如:Mr. Brown is said to have died of liver cancer.

  • 情态动词的被动语态:
    一、理解含情态动词的被动语态的概念含情态动词的被动语态说明某个被动性动作所反映出的感情和态度。
    初中阶段可用于被动语态的情态动词有“can、may、must、need、should”等,
    分别表示“能够被……”,“可以被……”,“必须被……”,“需要被……“,应该被……”等。

    二、掌握含情态动词的被动语态的不同句式的变换方法含情态动词的被动语态的疑问句、否定句的变化均借助于情态动词完成。
    (一)一般疑问句直接将陈述句被动语态中的情态动词提前。如:
    Mustthisworkbedoneatonce?这项工作必须立即完成吗?
    Shouldyourhomeworkbefinishedbeforesix?你的家庭作业应在六点前完成吗?
    (二)特殊疑问句由疑问词加上一般疑问句被动语态构成。如:
    Whenmustthisworkbedone?这工作必须在什么时候完成?
    Wherecanthelostbookbefound?这本失踪的书能在什么地方被找到?
    (三)反意疑问句借助情态动词构成附加疑问部分。如:
    Thisbridgecanbebuiltnextyear,can'tit?这座桥明年能建成,是吗?
    Thisbookshouldn'tbetakenoutofthelibrary,shouldit?这本书不应被带出图书馆,是吗?
    (四)否定句在情态动词后面加上“not”或“never”即可,但“must”表“必要”时否定式为“needn't”。如:
    Thisworkneedn'tbedoneatonce.这项工作没必要立即做。Thisdustbinshouldn'tbeputhere.这个垃圾箱不应放在这儿。

    三、含情态动词的被动语态的一般疑问句的回答含情态动词的被动语态的一般疑问句的回答应保留原情态动词,
    但“must”表“必须”时,其否定回答应用“needn't”、“need”表“必要”时,其肯定回答应用“must”。如:
    —Shouldmyexercisesbefinishedtoday?我的作业应在今天完成吗?
    —Yes,theyshould.是的,应在今天完成。(No,theyshouldn't.不,不应在今天完成。)
    —Musthisexercisebookbehandedinatonce?他的练习本必须立即上交吗?
    —Yes,itmust.是的,必须立即上交。(No,itneedn't.不,不必立即上交。)
    —Needhebeoperatedonatonce?他必须立即手术吗?
    —Yes,hemust.是的,他必须。(No,heneedn't.不,他不必。)

  • 考点名称:倒装句

    • 倒装句:
      为了强调、突出等语的目的而颠倒原有语序的句式叫做倒装句。在倒装句中,颠倒了的成分可以恢复原位而句意基本不变,句法成分不变。

    • 倒装句使用情况:
      A. 在疑问句中
      各种疑问句一般地说都是倒装语序。例如:
      Will they come to see us this weekend ? 这个周末他们将来看我们吗?
      Are you talking about the film you saw last Monday ?
      你们是在谈论你们上周一看的那部电影吗?
      Can you speak another foreign language except English?
      除开英语,你还能说另一种外语吗?
      Where did you buy the dictionary, in the book store nearby or in Xinhua bookstore?
      你在哪儿买的这本词典,是在附近的书店还是在新华书店?
      She is not a student, isn't she ? 她不是个学生,对吗?

      B. 在感叹句中
      某些感叹句也用倒装语序。例如:
      Isn't it a beautiful garden ! 多么美丽的花园啊!
      What a beautiful garden it is ! 多么美丽的花园啊!
      (在这种句式中,主语在谓语之前,属于自然语序。对于主语和谓语而言,语序没有倒装。)
