英语翻译But disappointed graduates are learning that it can no l

但是失望的毕业生正意识到,它也不再能吸收一支受过训练的二十二岁青年组成的军队了.
不知道对不对……没有语境?它是谁?
不是同位语,是learning 的宾语,宾语从句.同位语大多是先出现一个名词,比如
But disappointed graduates are learning the fact that it can no longer absorb an army of trained twenty-two-year-olds,either.
the fact 的解释就是that it can no longer absorb an army of trained twenty-two-year-olds,either.
这个句子就是the fact的同位语,即同位语从句.
