答案：Dear teachers and schoolmates,
I'm writing to call on all of you to give a helping hand to our schoolmate Xiao Ming.
Xiao Ming is facing a terrible situation now. He has a serious heart disease and needs an immediate operation to save his life. But his family is very poor and can't afford the expensive medical fees. The high cost has become a huge barrier between him and recovery.
To help Xiao Ming get the treatment he needs, the Students' Union will hold a charity sale on the school playground this Saturday morning from 9:00 to 11:30. We will sell different kinds of things, including handmade cards, second-hand storybooks and beautiful handicrafts made by students. All the money we raise will be used to pay for Xiao Ming's operation.
Your kindness can make a big difference to Xiao Ming's life. No matter how much you contribute, every bit of help counts. Please come and join us to support Xiao Ming!

解析：
这是一篇呼吁类公开信，写作需采用“共情引入-困境说明-活动介绍-发出呼吁”的逻辑结构。开头点明写信初衷，用简洁语言介绍肖明的病情与家庭经济困境，引发读者共情；接着明确设计的公益活动（如义卖）的时间、地点与用途；最后用真诚的语言号召全校师生参与，确保内容完整、语句通顺，符合八年级英语写作的词汇与句式要求。
