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）以單數名詞或代詞，動詞不定式短語作主語時，謂語動詞要用單數；主語為復數時，謂語用復數，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。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。例如：
His teacher and friend is a beautiful girl.
The poet and writer has come.
�。�3）由and連接的并列單數主語之前如果分別由each, every修飾時，其謂語動詞要用單數形式。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.
