My favourite celebrity is Jungkook from BTS. He is a talented singer, dancer, and performer. I like him because he works very hard and always gives his best on stage. He is also humble and kind to his fans. Jungkook inspires me to never give up.
My favourite celebrity is Taylor Swift. She is a talented singer and songwriter. I love her music because her lyrics are meaningful and emotional. She is also kind and supports many charities. Taylor inspires me to be confident and follow my dreams.

Students should throw rubbish into bins and avoid littering in the classroom or schoolyard. They can help recycle paper, plastic, and cans. Planting more trees and watering the plants often also helps keep the school green. Students should not write or draw on the desks or walls. Keeping the school clean and green is everyone's job, so students should work together and remind each other to take care of their environment.
