Yuck is the noise you make when something disgusts you. Not when it is dangerous or sad — when it is gross. Rotten food, a dirty sink, a smell in the drain, a fish eye on your plate. You see it, your face wrinkles, and out comes yuck.

Yuck is the noise you make when something disgusts you是東西讓你覺得噁心時發出的聲音. Not不是 when it is dangerous or sad危險或難過的時候 — when it is gross而是噁心的時候. Rotten food腐爛的食物, a dirty sink髒的水槽, a smell in the drain排水孔的臭味, a fish eye on your plate盤子裡的魚眼睛. You see it你一看到, your face wrinkles臉就皺起來, and out comes yuckyuck就脫口而出

It is an exclamation它是感嘆詞, so it stands alone所以會自己單獨出現: "Yuck! What is that smell?"像「Yuck!

You would not write it in an essay, and you would not say it about the food your host just cooked for you unless you want a very quiet evening. In Taiwan a student's instinct is to reach for it whenever something is bad — but it is only for the disgusting kind of bad, the kind you feel in your stomach.
