I’ m lucky to study in this beautiful school. The teachers are great. They always try to make their lessons lively and interesting. The classmates are lovely and friendly. The school life is rich and colorful. They make me happy every day.
In the past three years, I am hardworking and have made great progress. I do well in the exams. I am good at communicating and I like to make friends with others.
However, I have problems, too. I will spend less time online. I will do more sports and become stronger.
Thank you my teachers and classmates. Wish my school more beautiful, my teachers and
