do sth. oneself 表示不靠別人的幫助而自己做某事,與do sth. by oneself 意思差不多,但by oneself 還表示“獨自,孤單,一人”的意思,作狀語。all by oneself 是by oneself的強調(diào)式。
He made the kite himself . 他自己做了那個風箏。
He found the way home by himself . 他自己找到了回家的路。
I like to go walking by myself . 我喜歡一個人散步。
Did you do it all by yourself ? 是你自己一個人做的嗎?
She could do the work all by herself . 她自己一個人就能做這項工作。
提示
leave sb. by oneself表示“把(某人)一個人丟下”,相當于leave sb. alone。
She left the boy by himself at home. 她把那個男孩一個人丟在家里了 。
She left the boy alone at home.
