中文原文：

他親筆寫了這封信。

錯誤譯文：

He wrote the letter with his own pen.

正確譯文：

1) He wrote the letter himself.

2) He wrote the letter in his own hand.

翻譯加油站：

“親筆”是“親自動筆”的意思。而with his own pen的意思是“用他自己的筆”。“親自”和“親身”可以譯為oneself，in person, personally 等。例如：她親身經歷了這個事。She experienced the event herself/in person /personally.

“親眼”、“親耳”、“親口”和“親手”都有一個身體部位名詞，譯成英語可以用 with one's own + 身體部位名詞(eyes, ears, mouth, hands) 表示。例如：這位外國朋友親眼看見了中國近年來發生的巨大變化。The foreign friend saw with his own eyes the great changes that had taken place in recent years in China.媽媽親手給我做了一碗面條。My mother cooked a bowl of noodles for me with her own hands.我簡直不能相信我親眼所見和親耳所聞的事情。I could hardly believe what I had seen with my own eyes and heard with my own ears.
