中考英語難點語法詳解:主謂一致
謂語受主語支配,須和主語在人稱和數(shù)上保持一致,這叫做主謂一致。主謂一致一般遵循三條原則:語法一致原則,意義一致原則和就近一致原則。
1. 語法一致的原則
。1)以單數(shù)名詞或代詞,動詞不定式短語作主語時,謂語動詞要用單數(shù);主語為復數(shù)時,謂語用復數(shù),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連接的并列成分作主語時,謂語動詞用復數(shù)。例如:
Both he and I are right.
Mr Black and Mrs Black have a son called Tom.
但并列主語如果指的是同一人,同一事物或同一概念,謂語動詞用單數(shù)。例如:
His teacher and friend is a beautiful girl.
The poet and writer has come.
。3)由and連接的并列單數(shù)主語之前如果分別由each, every修飾時,其謂語動詞要用單數(shù)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.
