by myself的音標(biāo)是["ba? m?lselv]，基本翻譯是“獨(dú)自地；自己”，速記技巧是：by+反身代詞=自己做某事。

By myself的英文詞源是by（通過）+oneself（自己）。這個(gè)詞的含義是“獨(dú)自地，單獨(dú)地”。

By myself的變化形式有：單數(shù)形式by oneself，復(fù)數(shù)形式by ourselves。

相關(guān)單詞有：

1. solitude（獨(dú)處，孤獨(dú)）：這個(gè)詞由solus（獨(dú)自）+itude（狀態(tài)）構(gòu)成，表示獨(dú)自一人的狀態(tài)。

2. isolation（孤立）：這個(gè)詞由iso（等同）+lay（放置）+sion（狀態(tài)）構(gòu)成，表示獨(dú)自放置的狀態(tài)，即孤立。

3. lone（孤獨(dú)的）：這個(gè)詞由lo(n)e（孤獨(dú)的）+nous構(gòu)成，直接表示孤獨(dú)的狀態(tài)。

4. alone（單獨(dú)的）：這個(gè)詞由al(l)one（單獨(dú)的）構(gòu)成，表示獨(dú)自一人。

5. self-reliance（自立）：這個(gè)詞由self（自己）+reliance（依賴）構(gòu)成，表示獨(dú)自依賴自己實(shí)現(xiàn)目標(biāo)的能力。

以上單詞都與by myself的含義和用法密切相關(guān)，體現(xiàn)了獨(dú)立、獨(dú)自的特點(diǎn)。每個(gè)單詞都有其獨(dú)特的含義和用法，體現(xiàn)了英語語言的豐富性和多樣性。同時(shí)，這些單詞也反映了人類對(duì)于獨(dú)自行動(dòng)和獨(dú)立精神的追求和贊美。
