一、具體含義的不同。
1、on one"s own意為“靠自己的力量、獨自地”，在句子中可做狀語，獨立使用，相當於一個副詞。
2、by one"s own不可以單獨使用，因為其中的own是形容詞，後接名詞，才可以在句子中充當狀語。例如中文“靠某人自己的雙手”可以表達為："by one"s own hands"。
二、實際運用舉例。
1、on one"s own
He never joins with us.He always plays on his own.
他從不和我們在一起。他總是自己單獨玩。
He drew the conclusion by building on his own investigation.
他根據自己的調查研究作出結論。
2、by one"s own
He must not measure his neighbour"s corn by his own bushel.
他不應該拿自己的標準去衡量鄰居。
The story goes that he died by his own hands, but this looks rather suspicious.
謠傳他已經自殺，但我對此半信半疑。
