by yourself/oneself意味着独自做某事。另一方面, for oneself讲的是目的。所以,这里的for oneself ,是指父亲为自己而活,而不是为他人而活。独自live by oneself意味着独自生活。例: I drove by myself this morning since I got my license yesterday. (我昨天拿到了驾照,所以今天早上我一个人开车。) 示例: She went on the trip for herself. She needed to relax. (她自己去旅行。她需要休息。) 示例: She went on the trip by herself. (她一个人旅行。)
