以下是一篇简短的英语中学生个人成长介绍：

Hello, everyone. My name is Li Hua, a 16-year-old student from China. I have been studying in my local high school since 2018.

When I was young, I was always fascinated by the world of science and math. I loved solving problems and finding the hidden patterns in numbers. That's why I chose to pursue science in high school.

In my freshman year, I found that the high school life was more challenging than I had expected. The courses were harder and the homework was piling up. It was also the first time for me to live away from home. However, I quickly adapted to the new environment and set myself on a path to success.

In my sophomore year, I joined the math club and started participating in various school activities. This helped me build my confidence and improve my leadership skills. I also started preparing for the college entrance exam, which would determine my future.

Now, as a junior, I am laser-focused on my studies and preparing for the college entrance exam. I am determined to achieve my goal and pursue my dream of becoming a scientist.

Looking back, I am proud of my growth and progress. I have learned how to balance my studies and extracurricular activities, how to face challenges, and how to believe in myself. I am excited about the future and look forward to what life has in store for me.

Thank you for listening to my growth story.
