do sth oneself与do sth by oneself 的区别

问题描述

She did the work herself.

She did the work by herself.

请问这两个句子的意思有区别吗？

总结起来就是：do sth oneself与do sth by oneself 有区别吗？

老师答疑

龙老师：

do sth oneself与do sth by oneself 有时有区别，有时没有区别：

do sth oneself 有两个意思：一是表示亲自做某事，二是表示独力做某事。

do sth by oneself 只表示：独力做某事。

所以：

She did the work herself. 她亲自做了这工作。/ 她独力做了这工作。

She did the work by herself. 她独力做了这工作。
