大好的天气如果突然下起雨，那么可能原本计划好的活动就不得不取消，着实令人扫兴！
当某人的计划不得不因为事或人而告停时，就可以用表达 “rain on someone’s parade”，也就是汉语里说的 “泼冷水，扫兴”。
- I hate to rain on your parade, but you’re not going home until you’ve finished that.
我不想煞风景，但是你完成这件事之前不准回家。 - They had planned to go to the beach at the weekend, but the weather just rained on their parade.
他们原本计划这周末去海滩玩，但糟糕的天气让他们很扫兴 。 - He was going to have a party on Friday, but his friends rained on his parade when they said that they were all busy.
他本想在周五开派对，但他的朋友们却泼了他一头冷水，都说太忙去不了。
