小学生英语作文自我介绍可以通过以下三个实用技巧来撰写：
技巧一：简洁明了，突出个人特点
在写自我介绍时，首先要确保内容简洁明了。由于小学生的英语水平有限，过于复杂的句子和词汇可能会让他们感到困惑。尽量使用简单、常见的词汇和句型来描述自己。
例如，你可以这样写：“Hello, my name is Li Ming. I am a primary school student from Beijing. I like reading books and playing basketball.”
技巧二：分段介绍，条理清晰
将自我介绍分成几个段落，每个段落介绍一个方面的内容，这样可以让作文更加条理清晰。
例如，你可以这样安排：
第一段：介绍自己的基本信息，如姓名、年龄、学校等。
第二段：介绍自己的兴趣爱好，如阅读、运动、音乐等。
第三段：描述自己的理想或未来目标。
例如：“Hello, my name is Li Ming. I am a seven-year-old boy from Beijing Primary School. I like reading books and playing basketball. My dream is to become a scientist when I grow up.”
技巧三：使用具体例子，增加生动性
在介绍自己的兴趣爱好时，可以使用具体的例子来增加作文的生动性。
例如，你可以这样写：“I like reading books because it can take me to different places and meet different people. Once I read a book about the space, and I felt like I was flying in the space.”
