Trees are an important factor contributing to the protection of green - clean - beautiful environment. After the Tet holiday, my school launched a tree planting ceremony for all teachers and students in the school. The homeroom teacher gave us a week in advance so that each of you could prepare a small seedling and a trimmers to bring to school. During the holiday, the students were crowded, the teachers also brought lots of seedlings. After that, the teachers gathered the students in a line and took us to the back garden of the school. Here, the soil has been divided into small plots and the holes have been dug. Teachers show us how to put trees into holes and fill the soil, water plants. Everyone was very enthusiastic about the work, though at first startling, but then everything became more mature. Teachers say the number of trees planted here until they become bigger will be transported to the city's highways and residential areas to help the city become greener, more air in the heart. This was a meaningful and unforgettable event.

   I think we can do many things to improve the environment around us.Firstly, we should turn off light when we go out. Secondly, we should turn off the tap when we brush teeth and wash dishes.Finally, we should recycle many things such as plastic, bottles, paper.
