64 oneself, by oneself和all by oneself
do sth. oneself 表示不靠别人的帮助而自己做某事，与do sth. by oneself 意思差不多，但by oneself 还表示“独自，孤单，一人”的意思，作状语。all by oneself 是by oneself的强调式。

He found the way home by himself . 他自己找到了回家的路。
I like to go walking by myself . 我喜欢一个人散步。
Did you do it all by yourself ? 是你自己一个人做的吗？

提示
leave sb. by oneself表示“把（某人）一个人丢下”，相当于leave sb. alone。
