- Mary didn’t have a decent meal for three months. (瑪麗三個月來沒有吃過一頓像樣的飯) (正)
- Mary didn’t have a descent meal for three months. (誤)
- Mary didn’t have a dissent meal for three months. (誤)
解說：這三個字或其中兩個字無論發音或拼字都非常相近，很容易讓人錯把馮京當馬涼。Decent 意為「像樣的；正派的；得體的；體面的」，是個形容詞。Descent 意為「下降；下坡；血統；墮落」，是個名詞。Dissent 意為「異議；不同意」，可當名詞和動詞用。
