二、 My Low- carbon Life
The environmental pollution is worse and worse today. Many trees are cut down, and water and air are polluted. As a student I try to have a low -carbon life to save energy and reduce pollution.
Firstly, I often walk to school. It can reduce air pollution. Secondly, I always turn off the lights and fans when leaving the classroom. Thirdly, I always make full use of paper and other school things and never waste water.
I wish more students to join me and make the earth more and more beautiful.
