Day667白发苍苍怎么说？white hair？那你也太直白了！

今天我们说gray这个颜色白发苍苍的老年人绝对不是white hair正确答案是：having gray hair 还记得英国诗人叶芝的那首经典诗歌“当你老了”吗？When you are old and gray and full of sleep and nodding by the fire.当你老了，满头白发，昏昏沉沉在炉火旁打盹。To become gray.To become old; age."Current community services can't keep up with the nation's rapidly graying population.当前的社区服务跟不上不断增长的老龄化人后步伐。 gray area 灰色地带（含糊不清之处）Eg.Between these two extremes, there is a lot of gray area. 在这两个极端之间，有很多灰色地带。 来一个有趣的短语吧all cats are gray at night / by night关了灯全都一个样Eg.In the dark of night, appearances do not matter (because it is so difficult to see anything.在黑暗的夜晚，外表并不重要(因为很难看到任何东西)。 A: "I can't believe you're going on a date with someone you've never met before! What if you don't think he's attractive?" B: "Ah, all cats are gray by night, so it will be fine."
