Dear teachers and students, hello!

My name is xxx, I am twelve years old, and my birthday is April 17th. I am a lovely Aries, and I have omnipotent type O blood. I graduated from Lixin Experimental Primary School.

I am the type of "quiet as a virgin and moving as a rabbit", with a pair of glasses on my nose, alas! It's all caused by computers! I'm not tall, but I'm short and lean. Focus is the essence!

My grades in primary school are not bad in my class, and I have won many prizes in various subjects. I used to be a monitor, squadron leader, captain and vice captain, and I was also a proud disciple of my teacher. However, this has become the past. Today, I'm in class with many experts, and I already feel the pressure. But I believe that pressure is motivation, and I will definitely try my best to refuel!

I like sports, running, skipping rope and table tennis. My primary school won many prizes in the sports meeting. I often participate in various activities organized by the school and get good grades. Many times, I am taken as an example.

In the past, my classmates and friends went to different middle schools, but few people went to Shuier No.2 Middle School. Therefore, in the new environment, I believe I will make more new friends, and I hope everyone will be willing to make friends with me.

Through my description, I believe everyone knows something about me. I hope we can get along well in the next three years of study.
