"半块心"用英语可以翻译为"half a heart". 这个短语源于英文儿歌"You Are My Sunshine"中的一句歌词："You are my sunshine, my only sunshine. You make me happy when skies are gray. You'll never know dear, how much I love you. Please don't take my sunshine away."（你是我的阳光，我唯一的阳光。你让我快乐，当天空灰蒙蒙的时候。亲爱的，你永远不会知道我有多爱你。请不要带走我的阳光。）这句歌词后来被改编成了许多不同的版本，其中有一个版本是这样的："You are my sunshine, my only sunshine. You make me happy when skies are gray. You'll never know dear, how much I love you. Please don't take my sunshine away. I'll love you till I die. You are my sunshine, my only sunshine. You make me happy when skies are gray. You'll never know dear, how much I love you. Please don't take my sunshine away. I'll love you till I die. Half a heart is not a whole. I need your love to make me whole."（你是我的阳光，我唯一的阳光。你让我快乐，当天空灰蒙蒙的时候。亲爱的，你永远不会知道我有多爱你。请不要带走我的阳光。我会爱你直到死亡。你是我的阳光，我唯一的阳光。你让我快乐，当天空灰蒙蒙的时候。亲爱的，你永远不会知道我有多爱你。请不要带走我的阳光。我会爱你直到死亡。半块心不是整块。我需要你的爱来让我整块。）
