被动语态地点是放by sb之前还是之后？books were brought to the lib

Question

被动语态地点是放by sb之前还是之后？books were brought to the library by us. a party was had by us at her home这两句怎么地点的位置不同呢

Answer 1

放在by sb之前，例如：The cake was eaten by Tom.你注意观察，这两句里的by sb都是放在被做了的事情后面的，书被带到图书馆被我们，聚会被举行被我们，你所谓的不一样，是因为bring to 是个短语，带到····，它跟被动语态是没有联系的。这知识一个提示地点的单词，不影响被动语态。被动语态的句式：sth was/were done +地点+by sb
例如：The cake was eaten in the room by Tom.

Answer 2

两者都可以，by sb 和 地点，你想侧重哪个，就把哪个放在前
