I want to change to my old deskmate.

You can gently tell the teacher, you say, teacher, I have been distracted in class recently, and my academic performance has not improved much. I think this has a great influence on the learning environment around me. My deskmate is very cute, but she always likes to make small moves in class. I know it doesn't have much influence on his study, but I can't. I am a quiet child, and I can't concentrate when others make small moves around me in class. I think my former deskmate is very good. He studies very well and can help me a lot in my studies. Can you let me transfer a post to study with him, so that our grades can be improved quickly? ...
