当这些词后面的名词有了 the, these, those等特指限定词修饰时，或其后的接的是 us, them 这样的人称代词时，则此时必须用介词 of。 three hundred of the /my/those students
two thousand of them
当这些词与 a few, several, many 等数目不很具体的词连用时，带不带复数词尾 -s 均可，但是注意：若不带复数词 -s, 其后的介词 of 可以省略；若带复数词尾-s, 则其后介词 of 不能省略。 some hundred persons 大约一百人
some hundreds of persons 几百人
There I saw several hundred foreign guests.
