hay fever（n.）
"also hay-fever，1825年，由 hay 和 fever 组成。在1828年以前也称为 summer catarrh； 在1820年代之前不太引人注目，有时被嘲笑为疾病中的“时髦”现象。"
People are apt to sneeze, in hot weather for example; and people do not die of sneezing now-a-days, as they did in days that no one knows any thing about. We cannot give six draughts a-day, at one and nine pence each, for sneezing: call it the hay-fever. What a wonderful man! what a clever man! he understands the hay-fever: call him in! Thus is the hay-fever among the last in the list of fashionables. ["On Fashions in Physic," London Magazine, October 1825]
"人们在炎热的天气里打喷嚏; 而如今，人们不会因打喷嚏而死亡，而那些已被人们遗忘的日子里却会。我们不能为打喷嚏每天花费6便士买一份药水，称之为“枯草热”。 这样的稀奇古怪之人！ 多么聪明的人！他懂得“枯草热”：立刻把他叫过来! " 因此，“枯草热”是时髦疾病列表中的最后一位。 ["On Fashions in Physic," London Magazine, October 1825]
