Our new hire studied metaphysics in college before switching to a career in marketing.

我們的新進員工大學時主修形而上學，後來才轉行做行銷。

Let's skip the metaphysics and focus on whether the shipment arrives by Friday.

我們先別談形而上學了，專心確認貨物週五前能不能送達。

The flight was delayed, so I read a short book on metaphysics at the gate.

班機延誤，所以我在登機門前讀了一本關於形而上學的小書。
