My ideal senior high school
We will be senior high school students soon. In my ideal senior high school, there are many green trees and beautiful flowers. The teachers there are patient enough to explain difficult problems to us, while the students are willing to share their joy and worries with each other. We have fewer subjects and less homework. After school we can take part in all kinds of activities. In this way, our new school life will be full of fun.
I hope to make any friends and enjoy my school life in senior high school. I also hope I can make great progress in my study.
