I do not want you hurt yourselves Tell her not move that book 这两句话有什么错误?为什么?为什么要加to呢？

I do not want you to hurt yourselves
Tell her not to move that book,tell sb. not to do sth.

I don't want you to hurt yourself. （若是你就用yourself，若指的是你们就是yourselves）
Tell her not to move that book.
自己看一次下。

I do not want you to hurt yourselves （want to do sth )
Tell her not to move that book,（tell sb.not to do sth.）--固定用法啊.
