青年歌手大赛（"youth singer competition"）通常指针对年轻歌手的比赛。这种比赛的来源可能源于人们对年轻人才的关注，以及对音乐的热爱。例如：
"The youth singer competition is a great opportunity for young musicians to showcase their talent and compete for prizes."（青年歌手大赛是年轻音乐家展示才华并争夺奖项的绝佳机会。）
"Many talented singers have been discovered through the youth singer competition over the years."（多年来，许多有才华的歌手都是通过青年歌手大赛被发掘的。）
希望这些例句对您有帮助。
