environment can make people feel happy and fit .To improve the environment means to improve our life.We should plant more trees and flowers around us .We shouldn’t cut them down .We should stop factories from pouring waste water into the river and waste gas into the air.Whenever we see litter on the ground ,we should pick it up and throw it into dusbins.Never spit in public.Don’t draw on public walls.It’s our duty to protect the environment.能不能给出中文？ 谢谢了。
