主谓一致的考点集汇谓语受主语支配,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:语法一致原则,意义一致原则和就近一致原则
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
