in mistake和by mistake的区别？

in mistake for 错当成 She took someone else's book in mistake for her own. 她把别人的书错当成自己的书拿走了. by mistake 错误地 She put salt into her tea by mistake. 她误把盐放进茶里去了. 望采纳，谢谢！

in mistake,是错当成。比如:Lining took someone else's book in mistake for her own(李宁把别人的书错当成自己的书拿走了）。 by mistake，是错误地做了某件事情，侧重于行为方面。如：Lining put salt into his tea by mistake（她误把盐放进茶里去了）。 in mistake,侧重于思想方面，是主观意识上的错误。 by mistake，侧重于行为方面，是行为错误。
