鑰匙的存在由來(lái)已久。最早的鑰匙可追溯到 4000 年前，由古埃及人用木頭制成。對(duì)鑰匙做出了一些改進(jìn)，改用金屬制造。不過(guò)自那以后，鑰匙差不多就再無(wú)變化。

我的譯文

The key has a long history, which can be traced back to 4,000 years ago, when it was made out of wood by ancient Egyptians.? Some improvements were made by the Romans with metal. But keys have remained almost the same since then.
