大家好！我叫李明，今年10岁了。我是北京市一所小学五年级的学生。今天我要用英语做一次简单的自我介绍，然后我会把内容翻译成中文。

My name is Li Ming. I am 10 years old. I am a fifth-grade student in a primary school in Beijing. Today, I want to make a simple self-introduction in English, and then I will translate it into Chinese.

我最喜欢的是数学和体育。在课堂上，我总是认真听讲，积极回答老师的问题。课后，我喜欢和朋友们一起踢足球或者打篮球。我觉得运动让我很健康，也让我更快乐。

I like math and PE best. In class, I always listen carefully and answer the teacher's questions actively. After class, I like to play soccer or basketball with my friends. I think sports make me healthy and happy.

我的家庭有四口人：爸爸、妈妈、我，还有一个可爱的妹妹。我们一家人非常和睦，经常一起看电影或者去公园玩。周末的时候，我们还会一起去郊游。

There are four people in my family: my father, my mother, me, and a lovely little sister. We have a very harmonious family. We often watch movies together or go to the park. On weekends, we also go on trips together.

我有一个梦想，就是长大后成为一名医生。因为我想帮助别人，让生病的人恢复健康。为了实现这个梦想，我现在要好好学习，努力锻炼身体。

I have a dream of becoming a doctor when I grow up. Because I want to help others and make sick people recover. To realize this dream, I study hard now and try to keep fit.
