记忆方法: 1）首字母DLBB祥林嫂丢了宝宝<==悲叹   “悲”由非和心构成，表示”违背心愿的现象”，如失望不满伤痛，”有声无泪曰悲”，如悲鸣悲叹悲愤悲伤；  ”哀”和悲同义，但除了表示悲，还表示悼念或怜悯2种意思，如哀悼默哀表悼念，哀怜哀其不幸表怜悯，即”哀”有3个意思。本意衣服上有个口有个洞，形容处境不顺利，如"诚知此恨人人有，贫贱夫妻百事哀"，如"乐而不淫，哀而不伤"，但现在本意很少用，常用以上3个意思

         2）悲叹的意思是表达悲伤mean to express grief or sorrow for something.   广雅: "悲，伤也", 说文: "悲，痛也"，可见伤痛是更基础的词，悲是伤痛在心里的表现   (sorrow悲伤强调内心而非表达，mourn哀悼强调表达而非内心，grief悲哀二者兼有，在2019-04-04 哀恸grieve-sorrow，只要记住mourn未必表示内心就可以了)
