School roof of whether they have faded but still uncertain, including two suites and three rooms for administrative areas. In my class very clean and tidy because we are very conscious of hygiene and clean.

The school's students are learning there are many shade trees and benches in the school yard, I love my school and I come to school every day.

The teacher told us to always obey the rules of the school, and we do not write graffiti on the desk to keep you clean and beautiful school.

I really like going to school because each met many friends, to meet teachers. This school is the place lit dream for me, I would later dream of becoming a teacher to teach at this school.

Mái trường cho dù họ đã phai mờ nhưng vẫn không chắc chắn, bao gồm hai dãy phòng và ba phòng cho khu vực hành chính. Trong lớp học của tôi rất sạch sẽ và ngăn nắp vì chúng tôi rất ý thức về vệ sinh và sạch sẽ.

Học sinh của trường đang học có nhiều cây xanh bóng mát và băng ghế trong sân trường, tôi yêu trường tôi và tôi đến trường mỗi ngày.

Các giáo viên nói với chúng tôi luôn tuân thủ các quy định của trường, và chúng tôi không viết vẽ bậy trên bàn làm việc để giữ cho bạn môi trường sạch sẽ và đẹp.

Tôi thực sự muốn đi học vì mỗi gặp nhiều bạn bè, để gặp gỡ giáo viên. Ngôi trường này là nơi thắp sáng ước mơ cho tôi, sau đó tôi sẽ ước mơ trở thành cô giáo dạy tại trường này.
