班级新蜜蜂用英语可以翻译为 "class newbie" 或 "class newcomer"。这个说法可能源于蜜蜂在自然界中是群居动物，它们经常需要新成员加入群体，所以将新成员称为"新蜜蜂"。下面是一些例句和中文翻译：

He is the class newbie, so he doesn't know many people yet. 他是班级新人，所以还不认识很多人。
As a class newcomer, she was nervous on her first day of school. 作为班级新成员，她在她的第一天上学时很紧张。
The class newbies were welcomed with open arms by their classmates. 班级新人受到了同学们热烈的欢迎。
