帮我把这句翻译成英文--昨天他捡到我丢失的一本图书馆的书

Yesterday, he picked up one of my book which was lent from the library.

Yesterday he picked up the book belonging to library, which I lost.

肯定对哦
这里有两个定语，一个是图书馆的，用belonging to这个短语表示
一个是我丢失的，用定语从句表示，由于前面有图书馆，所以这里用非限定性定语从句

Yesterday, he picked up one of my book which was lent from the library.

He picked up a book yesterday that the one I borrowed from the library but lost.

Yesterday he picked a library book which I lost.
