本人男生,就是高一开学入班的自我介绍,老师要求用英语,100词左右,

Hi, everyone! I am glad to introduce myself to you. My name is （你自己的名字）. I am a seventeen-year-old boy from（你原先毕业的中学的名字） middle school. I am good at maths, physics and chemistry, but my English is really not good. It isn't easy for me to understand what the English teacher says, if she speaks too quickly. So I hope everyone here can give me a hand to improve my English. I am longing for making friends with you, and I would like to do my best to help each other. That's all. Thank you!
