主谓语法一致的原则

编辑: 逍遥路 关键词: 初中英语 来源: 高中学习网


 谓语受主语支配,须和主语在人称和数上保持一致,这叫做主谓一致。主谓一致一般遵循三条原则:一致原则,意义一致原则和就近一致原则。

  1. 语法一致的原则

  (1)以单数名词或代词,动词不定式短语作主语时,谓语动词要用单数;主语为复数时,谓语用复数,例如:

  He goes to school early every morning.

  The children are playing outside.

  To work hard is necessary for a student.

  (2)由and或both……and连接的并列成分作主语时,谓语动词用复数。例如:

  Both he and I are right.

  Mr Black and Mrs Black have a son called Tom.

  但并列主语如果指的是同一人,同一事物或同一概念,谓语动词用单数。例如:

  His teacher and friend is a beautiful girl.

  The poet and writer has come.

  (3)由and连接的并列单数主语之前如果分别由each, every修饰时,其谓语动词要用单数形式。例如:

  In our country every boy and every girl has the right to receive education.

  Each man and each woman is asked to help.

  (4)主语是单数时,尽管后面跟有 but ,except, besides, with 等介词短语,谓语动词仍用单数。例如:
  The teacher with his students is going to visit the museum.

  Nobody but two boys was late for class.

  Bread and butter is a daily food in the west.

  (5) 一些只有复数形式的名词,如people, police, cattle, clothes等作主语时,谓语动词要用复数。例如:

  A lot of people are dancing outside.

  The police are looking for lost boy.

  (6)由each, some, any, no, every 构成的复合代词作主语时,谓语动词都用单数。例如:

  Is everybody ready?

  Somebody is using the phone.

  (7)有两部分构成的物体的名词,如glasses, shoes, trousers, chopsticks, scissors 等作主语时,谓语动词用复数。例如:

  Where are my shoes? I can’t find them.

  Your trousers are dirty. You’d better change them.

  如果这类名词前用了a pair of等,则往往用作单数,谓语动词的单复数形式往往取决于pair的单复数形式。例如:

  Here are some new pairs of shoes.

  My new pair of socks is on the bed.
