“高中开学自我”常见的英语表述可以是：\Self-introduction at the beginning of high school\ 或者 \Self-presentation at the start of high school\
以下是对这两个表述的解释：
“Self-introduction” 意思是“自我介绍”，“at the beginning of”表示“在......的开始”，所以 “Self-introduction at the beginning of high school” 就是“在高中开始时的自我介绍”。
“Self-presentation” 也有“自我展示、自我呈现”的意思，“at the start of”与“at the beginning of”意思相近，都表示“在......的开端、起始”，“Self-presentation at the start of high school” 则可理解为“在高中开端的自我展示”。
