开场白通常是为了引入活动、节目或演讲的介绍性话语。以下是一个小学英语表演开场白示例：
Ladies and gentlemen, boys and girls, welcome to our English performance show! Today, we will present a series of exciting and interactive performances to showcase the beauty of the English language. Whether you're here to see your classmates perform, or to enjoy the show, we hope that you will have a great time!
