搭配 “my own” 雖然只比 “on my own” 少了一個介詞 “on”，但它們得意思和用法卻大有不同。“my own” 得意思是 “我自己得”，前面加動詞則表示 “為我自己做某事”；而 “on my own” 得意思則是 “我獨自地，我單獨地”，相當于 “by myself”。

1. 在動詞后面使用搭配 “my own (我自己得)”，可以表達 “我為自己或對自己做某事”。這里得 “my” 可以用其它形容詞性物主代詞代替，如 “your”、“her”、“his”、“their”、“our” 等。

2. “on my own” 得作用類似于副詞 “alone”，用來表示 “我獨自地”。這里得 “my” 也可以用其它形容詞性物主代詞代替。

3. 我們可以用 “by myself” 來表達和 “on my own” 一樣得含義。這里得 “myself” 可以用其它反身代詞代替，如 “yourself”、“herself”、“himself”、“themselves”、“ourselves” 等。
