many a student的謂語動詞用三單形式。many a意思是許多。例如，I met him many a time in the bus.我在公共汽車上見過他多次。

many a 的用法

例題：Many a boy and many a girl__it since then.

A.have seen B.has seen

選B。“many a+單數(shù)可數(shù)名詞”形式上為單數(shù)，但意義上為復數(shù)(意為“許多”).

若用作主語，其謂語通常與形式一致而不與意義一致(即謂語用單數(shù))

many a 后面接可數(shù)名詞的單數(shù)，意思是許多，但是后面的謂語動詞應該用三單形式。

如 Many a student likes reading.許多學生喜歡讀書。

many a student與many students

many a 就是許多的意思,和many意思一樣,只是用法不同

many a 加可數(shù)名詞單數(shù),謂語動詞用單數(shù),而many+可數(shù)名詞復數(shù),謂語動詞也用復數(shù)

many a+名詞單數(shù)=many+名詞復數(shù)，都是很多的意思。
