中午，爸爸在津津有味地喝啤酒。他喝得脸红红的，像只煮熟的`大螃蟹。我趁爸爸不注意，偷偷地把一勺醋放进了酒杯里。
At noon, dad was drinking beer with relish. He drinks red like a cooked crab. I secretly put a spoonful of vinegar into the glass when dad didn't notice.
爸爸喝了一口，皱起了眉头说：“味道怎么变苦了?”我捂着嘴巴偷偷地笑了!
Dad took a sip, frowned and said, "how can the taste become bitter?" I covered my mouth and secretly smiled!
