Mary was looking at her in the mirror 是“瑪麗正在照鏡子”嗎？
這位網(wǎng)友的翻譯有問題，錯誤就出在代詞用錯了，應(yīng)該使用“反身代詞”(也叫“自身代詞”)herself，而不是“賓格代詞”her。從語法和邏輯兩方面考慮，如果動作的施事者(發(fā)出者)又充當(dāng)了動作的接受者，那么必須使用反身代詞，不能使用賓格代詞。因為在同一個句子中，賓格代詞不表示主語本人，而是另外一個人，反身代詞和賓格代詞的差別就在于此。Mary was looking at her in the mirror.這個句子本身不錯，但意思是：瑪麗正在鏡子里看她(網(wǎng)友本人)。
