    主语是第三人称单数有以下几种情况: 

    (1) 不可数名词做主语:
    Some water is in the glass 

    (2) 单个的可数名词做主语:

    The girl is Chinese.  My watch is on the dresser. 

    (3) He ,she , it 等代词单个做主语: 
    He is in the tree. She likes her family very much.

    (7)单个数字作主语时:

    否定句:
    在主语的后面实义动词前加doesnt(注意实义动词应恢复原形。)     

    主语(单三)+doesn + 动词原形+其他 

    Jim likes football变否定: Jim doesn’t like football             

    He has lunch at school. 变否定:He doesn’t have lunch at school.   


    一般疑问句及答语,在句子前面加助动词does. 实义动词恢复原形

    Does your father work ? Yes, he does. /No, he doesn’t    


    特殊疑问句:特殊疑问词+一般疑问句 

    特殊疑问词+ does +主语(单三)动词原形+其他         

    Where does a bird live ?         

    How does she go to school 

  • 考点名称:被动语态

    • 语态:
      是动词的一种形式,它表示主语和谓语的关系。
      语态有两种:主动语态和被动语态。
      如果主语是动作的执行者,或者是说动作是由主语完成的,要用主动语态;
      如果主语是动作的承受者,或者是说动作不是由主语而是由其他人完成的,则用被动语态。

    • 被动语态的构成:
      被动语态的基本结构:
      主语+be +过去分词(+by+动作的发出者)
      ① 一般现在时:am/is/are+过去分词
      如:Trees are planted every year.
      ② 现在进行时 am/is/are+ being +过去分词
      如:The road is being repaired. 
      ③ 现在完成时 have/has + been +过去分词
      如:The work has been finished.
      ④ 一般过去时 was/were + 过去分词
      如:The story was told by him.
      Many birds were killed last year.
      ⑤过去进行时 was/were+ being + 过去分词
      如: The new house was being painted when I got home.
      ⑥过去完成时 had +been+ 过去分词
      如: He told me that the work had been finished.
      ⑦一般将来时  will +be + 过去分词
      如:The problem will be discussed tomorrow.
      ⑧ 过去将来时 would/should +be +过去分词
      如: He said that the Christmas tree would be put up soon.
      ⑨情态动词的被动语态
      情态动词+ be +过去分词    
      如:The problem must be solved soon.
      Children should be taught to love animals.

    • 被动语态使用注意:
      1. 不及物动词无被动语态。 如:happen, break down, come out......
      What will happen in 100 years.
      The dinosaurs disappeared about 65 million years ago.
      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.
