a great many后直接接復數名詞，動詞用復數。用于肯定句中，相當于many，a large number of。

a great many 與 a great many of 的用法區(qū)別

1.a great many 與 a great many of 的用法區(qū)別，可以簡化為 many 與 many of 的用法區(qū)別。

many既是限定詞，用于修飾名詞，也是不定代詞，代替名詞。在many farmers中，many是限定詞；在many of短語中many是代詞。通常情況下代詞后接of...時，of后應該用特指的名詞或代詞。

例如 some students, some of the students；either side 與 either of the sides；much money 與 much of the money，以及 many soldiers 與 many of their soldiers 等。（當然，也有少量代詞用法特殊的，比如 both (of) his daughters 中的 of 可有可無，這與 both 這個限定詞的定位有關，在此不擬多談。）

2.因為many of修飾名詞時，是代詞，而many修飾名詞時是限定詞，這樣也造成了一些用法區(qū)別。可以說many of his friends,但不說many his friends,因為many是后位限定詞，his是中位限定詞，his須置于many之前。所以須將詞序改為his many friends才合適。
