搭配 “my own” 虽然只比 “on my own” 少了一个介词 “on”，但它们得意思和用法却大有不同。“my own” 得意思是 “我自己得”，前面加动词则表示 “为我自己做某事”；而 “on my own” 得意思则是 “我独自地，我单独地”，相当于 “by myself”。
1. 在动词后面使用搭配 “my own (我自己得)”，可以表达 “我为自己或对自己做某事”。这里得 “my” 可以用其它形容词性物主代词代替，如 “your”、“her”、“his”、“their”、“our” 等。
Can you make your own decision, please?
The little girl is doing her own laundry!
He makes his own dinner every day.
2. “on my own” 得作用类似于副词 “alone”，用来表示 “我独自地”。这里得 “my” 也可以用其它形容词性物主代词代替。
I think she likes spending time on her own.
He lives on his own.
We were on our own when the doorbell rang.
3. 我们可以用 “by myself” 来表达和 “on my own” 一样得含义。这里得 “myself” 可以用其它反身代词代替，如 “yourself”、“herself”、“himself”、“themselves”、“ourselves” 等。
I think she likes spending time by herself.
He lives by himself.
