一、写作思路
基本就是按照题目的提纲来写了，我们需要补充的是介绍写信人liyuan的一些信息，是哪个班级的学生。所以，开头需要介绍一下自己，否则Tim也不知道的呀，中间就重点介绍晚会的流程和注意内容，结尾就提出希望Tim发言的希望即可。
二、双语范文参考
Dear Tim
Hello! I'm Li Yuan from class 8 (1) of Meimei middle school.
I'm writing to you mainly to invite you to our class's orientation party. We will hold a welcome party on the evening of December 1 in our eighth year (1). Our party agenda mainly includes three items:
First, each student introduces their main situation, including where they come from, what interests and hobbies they have, and draws in the distance and feelings between the students; Second, watch students' talent show. The students in our class prepared some wonderful programs, including dance and quyi performance; Third, teachers and students have fun together. The teacher introduces some requirements and new regulations of the new semester, which makes it easier for students to adapt to the life of the new semester. At the same time, teachers and students sing and dance together to work hard and struggle together in the new semester
The above is the basic process of our class's orientation party. I look forward to you attending our class's orientation party. At that time, you will make a brief speech at the party to let everyone have a deeper understanding of you.
Your student Liyuan.
亲爱的蒂姆（Tim）:
您好。我是漂亮中学八年（1）班的李源同学。
给你来信，主要是想邀请您参加我们班的迎新晚会。我们八年（1）将于12月1日晚上举行迎新晚会，我们的晚会议程主要有三项：
一是各位同学分别介绍自己的主要情况，包括来自哪里，有什么兴趣爱好，拉进同学之间的距离和感情；二是观看学生才艺表演。我们班的同学准备了一些非常精彩的节目，有舞蹈、有曲艺表演；三是师生同乐节目。老师进行新学期的一些要求和新的规定知识介绍，让同学更加容易适应新学期的生活。同时，老师和同学一起欢歌起舞，共同在新的学期一起努力和奋斗
以上是我们班迎新晚会的基本流程，很期待您可以参加我们班的迎新晚会，届时在晚会中做个简短发言，让大家对你有一个更加深刻的认识。
您的学生李源（liyuan）
