Oneself is the reflexive form of one — the same job as myself after I, or yourself after you. You use it when the person you mean is that careful, general one: "One should be kind to oneself." It can also put weight on the idea that you do the thing, not someone else: to do it oneself.

Oneself是 is the reflexive form of one one的反身形式——the same job as myself after I跟I後面接myself一樣的作用，or yourself after you或you後面接yourself一樣。You你 use it when the person you mean用在你指的那個人 is that careful, general one就是那個講究、泛指的one的時候："One should be kind to oneself."「One should be kind to oneself.」（一個人應該善待自己。）It它 can also put weight on the idea也可以用來強調 that you do the thing, not someone else這件事是你自己做的，不是別人：to do it oneself自己動手做。

It is quite formal, and it belongs with the pronoun one. Textbooks like it.

It它 is quite formal相當正式，and it它 belongs with the pronoun one是跟one這個代名詞配一起用的。Textbooks課本 like it很喜歡用它。

Though actually, everyday English often runs away from one altogether. Many people say you instead: "You have to be kind to yourself." If your subject is I, she, they, or we, oneself is the wrong word; you need myself, herself, themselves, or ourselves.

Though actually不過其實，everyday English日常英文 often runs away from one altogether常常整個避開one不用。Many people很多人 say you instead改說you："You have to be kind to yourself."「You have to be kind to yourself.」If your subject is I, she, they, or we如果你的主詞是I、she、they或we，oneself oneself is the wrong word就是用錯字；you你 need myself, herself, themselves, or ourselves需要用myself、herself、themselves或ourselves。

Older writing sometimes has one's self as two words. Today we write oneself as one word.

Older writing較早期的寫法 sometimes has有時候會把 one's self as two words one's self寫成兩個字。Today今天，we我們 write oneself as one word把oneself寫成一個字。
