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;主語為複數時,謂語用複數,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bothand連線的並列成分作主語時,謂語動詞用複數。例如:
Both he and I are right.
Mr Black and Mrs Black have a son called Tom.
但並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.
