先通過這段簡短對話，體會一下senior citizen的含義：
Helen：We're throwing a retirement party for you this Sunday.
Joey：Thanks.I can't believe I am a senior citizen now.
海倫：這個星期日我們會為你舉辦退休派對。喬伊：謝謝，真不敢相信我加入銀髮族了。
senior citizen老年人；銀髮族senior citizen所界定的長者，不只是年齡和生理狀態上的年長，也是在社會統計和行政體制中，與多數人對比所界定出的範疇。一般是指60或65歲以上，已經從職場退休，享有退休金和社會福利的人群。
看看老外聊天時怎麼用senior citizen：
Peter: My pension will help pay the cost of my round-the-world cruise Tracy: What a life! I still have three more years to go.
Peter: Well, I sometimes wonder if Il miss the nine-to-five life.
Tracy: I am sure you will enjoy all the free time you have now.
Peter: You' re right. I should enjoy being a senior citizen.
彼得：我的退休金足以支付我搭郵輪環遊世界的費用。
特蕾西：這生活也太棒了！我還得再工作三年才能退休。
彼得：不知道我會不會想念朝兒晚五的生活。
特蕾西：我相信你會很享受自己的空閒時間。
彼得：也對，我應該好好享受銀髮族的生活。
