In the English-speaking world, it is customary to sing the song “Happy Birthday to You” to the birthday person. Do you know that it was originally written as a song to greet students in the morning? Two American kindergarten teachers, Mildred Hill and her sister Patty Hill wrote the song. In 1893, Mildred, who studied music, came up with the melody and Patty added some lyric to it and the song became “Good Morning to All”, which they sang every morning to their students. And the lyrics ran like this: “Good morning to you. Good morning to you. Good morning, dear children. Good morning to all.”

在英语国家，人们习惯于为生日的人唱“生日快乐”这首歌。你知道吗，这首歌最初是作为一首早晨问候学生的曲子写的吗？两位美国幼儿园教师，米尔德里德·希尔和她的妹妹帕蒂·希尔创作了这首歌。1893年，学习音乐的米尔德里德创作了旋律，帕蒂为它添加了一些歌词，这首歌成为了“大家早上好”，她们每天早上都唱给她们的学生听。歌词是这样的：“大家早上好，大家早上好，亲爱的孩子们，大家早上好。”

Later the title of the song was known as “Good Morning to You” when it was used for children to sing to their teacher. And the third and fourth lines became “Good morning, dear teacher. Good morning to you.” 

后来，这首歌的标题被称为“大家早上好”，当它被用来让孩子们唱给他们的老师听时。第三和第四行变成了“亲爱的老师，大家早上好。”

In 1924, the song appeared in a book of music edited by Robert Coleman. And a second verse, “Happy Birthday to You,” was added to it. 

But it is unclear who supplied the words to the second verse. This second verse quickly became more popular than the first, and within a short time of the book’s publication, the song was known to all as “Happy Birthday to You.” And by mid-1930s it was used frequently in movies, radio shows, and Broadway musicals without the Hill family’s permission. A third sister, Jessica Hill, decided to act on behalf of her elder sisters. She filed a suit to prove that “Happy Birthday to You” was their song with different lyrics. She won in 1934, and now every time “Happy Birthday to You” is sung publicly, the Hill family gets paid.

1924年，这首歌出现在罗伯特·科尔曼编辑的一本音乐书籍中。并为它添加了第二段歌词，“生日快乐”。但不清楚是谁提供了第二段歌词。这第二段歌词很快就比第一段更受欢迎，书籍出版后不久，这首歌就被称为“生日快乐”。到了1930年代中期，它经常在电影、广播节目和百老汇音乐剧中使用，而没有得到希尔家族的许可。第三个姐妹，杰西卡·希尔决定代表她的姐姐们采取行动。她提起诉讼，证明“生日快乐”是她们的歌曲，只是歌词不同。她在1934年胜诉，现在每次“生日快乐”公开演唱时，希尔家族都会得到报酬。
