用英语描述情景并作适当发散,两三分钟就够了～好的还有追加哦～～～

A boy was licking the rest sauces on the plate after he finished his meal, then his mother said “Did you know in some cultures it's considered rude to lick your plate?”
the boy puzzled and ask“why?”
“bucause in china,licking plates after having meals is considered rude and inelegant!” answered his father.
then the boy said “ok.. but we are in America now”
his father said “Yes.. but in a chinese restaurant”

译文：
一个男孩在用完餐后去舔那碟子上剩下的酱汁，于是他母亲对他说“你知道吗？在某些文化里，舔碗碟是被认为很粗鲁的”
男孩很困惑，问“为什么呢？”
“因为在中国，人们认为餐后去舔碗碟是粗鲁而不雅的”他的父亲回答说。
于是男孩说“好的。。。但是，我们现在在美国啊”
他父亲说：“对啊，但是在一家中式餐馆啊”

觉得不够长我还可以帮你加~

A boy was tucking the last drop of rice into his mouth and as he began to put his tongue on the brim of the plate when his mother shouted; "Do u know that it's considered rude to lick your plate"?
