你食咗未？

同朋友去食飯，點菜時會問吓人：「你有冇唔食啲咩？」

"Anything you don't eat?" / "What don't you eat?"

因為西人很關注 食物敏感，所以禮儀上不可以準備一些賓客有敏感的材料或食物。比較普遍嘅有：海鮮、花生、蛋、MSG ( 味精，全名少人叫：mono-sodium glutamate )、奶 ( 其實系入面嘅乳糖 lactose) ...... 所以你會發以 United Airline 系唔會派花生做小食，而系派蝴蝶餅 pretzel。而 MSG 可以响海草、蕃茄同冬孤搵到，所以以前啲西人成日話敏感中餐。

反過來問就系 "What do you eat?" -- 你食啲咩？

就好似我考你，你知唔知蜻蜓食咩？Do you know what do dragonflies eat? 系問緊 general fact。但系如果要問人食咗セ：

"What have you eaten?" / "What did you have for lunch?" / "What did you have yesterday dinner?"

留意時式 tense：
-  have ... eaten 現在完成式 present perfect 嚟表示剛剛之意。有啲似中文嘅「咗」字咁。
-  did ... have ... ? 簡單過去式 simple past。因為動作動詞 action verb 作疑問句時必須加 do 呢個輔助動詞 helping verb。咁 tense 呢？講緊嘅動作係過去嘅，所以 do 要轉做 did。咁 did 咗就唔駛 had 啦！

咪問人「食咗乜」變成「食咩你」，好似動物片咁。
