one's own／oneself
如属于句子主语的“身内之物”（包括穿戴之物）或思想范畴内的东西，通常用one's own。
如：He cut his own hand．他割了自己的手。
I won't believe you until I've seen you in the jar with my own eyes． 我要亲眼看见你在坛子里才会相信。
?one's own有时可指代前面提到过的同类事物。
如：I don't need to borrow your pen．I've got my own．我不需要借你的钢笔，我有我自己的。
oneself: 反身代词，强调句子主语发出的动作的承受者就是主语“自身”，即主语本身就是动作的承受者。
如：The little child cannot look after himself．这小孩不能自己照顾自己。
（该句中用himself，因为the little child 既是动作执行者，也是动作承受者。）
The girl put on her new clothes and looked about herself in the mirror．
那姑娘穿上新衣服，对着镜子打量着自己。
3）oneself一般不作定语，而one's own则可以作定语。
如：This is myself's book．（×）
This is my own book．（√）
