口语对话： a wet blanket
讲解：该短语出自苏格兰小说家John Galt 的小说《劳里·托德》或《森林开拓者》。书中用了这一说法：“以前我来从来瀴有感觉到如此高兴”。I have never felt such a wet blanket before or since. 可能因为在潮湿的气候下，湿毯子令人不舒服吧，后人就用 a wet blanket 指让人扫兴的人或事。
支持范例：
The teenagers don't invite Bob to their parties because he is a wet blanket.

Don't be a wet Blanket. They all enjoy your going there with them.
别扫大家的兴。他们都希望你和他们一起去那里。
He was such a wet blanket at the party that they never invited him again.
他在那次聚会中异常扫兴, 人家再也不邀请他了。
