myself与by myself用法的不同

myself与by myself用法的不同

区别：
myself 是反身代词；
by myself 是介词加代词作宾语构成介宾结构。
释义：
● ● myself
|maɪˈself|
● (the reflexive form of I I的反身形式) used when the speaker or writer is also the person affected by an action

（用于动作影响说话人或作者时）我自己
例句：
I cut myself on a knife.
我用刀时割伤了自己。
I wrote a message to myself.
我给自己留了个便条。
I found myself unable to speak.
我发现自己说不出话了。
● used to emphasize the fact that the speaker is doing sth

（强调说话者在做某事）我本人，亲自
例句：
I'll speak to her myself.
我要亲自去跟她说。
I myself do not agree.
我本人不同意。
● ● by myself
● alone; without anyone else （我）独自，单独
例句：
I live by myself.
我自己一个人生活。
● without help （我）独立地
例句：
I painted the room all by myself.
我独自一人粉刷了屋子。

myself 有一个独特的用法，可以做代词的同位语，“我自己。。。”
I myself do agree with this opinion.我自己确实同意这个观点。
所以反身代词都有这个用法。
以上回答你满意么？追问by myself和myself在根本表达意思上有不同吗？/
