搭配 “my own” 虽然只比 “on my own” 少了一个介词 “on”，但它们的意思和用法却大有不同。“My own” 的意思是 “我自己的”，前面加动词则表示 “为我自己做某事”；而 “on my own” 的意思则是 “我独自地，我单独地”，相当于 “by myself”。
用法总结
1. 在动词后面使用搭配 “my own (我自己的)”，可以表达 “我为自己或对自己做某事”。这里的 “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” 的作用类似于副词 “alone”，用来表示 “我独自地”。这里的 “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” 一样的含义。这里的 “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.
- The kids went to school by themselves.
