they also have access to rare academic works needed for their studies in the libraries.为什么 句中用的是needed 呀?

应为是在他们的学习中被需要的学术著作 所以要用被动
完整的句子应该是they also have access to rare academic works (which are) needed for their studies in the libraries.
可以省略which are

在图书馆中,他们也存取了他们研究所需的稀有学术性作品.修饰work的一个定语从句

work就是主句的动词吧!!!! 后面needed for their studies in the libraries的是分句.

动词过去式变成的形容词,翻译作 必要的,需要的

needed 是用来修饰academic works的,过去分词表被动,人需要academic works(主动),academic works被需要(被动)

academic works 是被动,被学习所需要。
