Taking car of our nvironmnt is our duty.But how w can do to mak our nvironmnt mor bautiful? At first,w must mak ourslvs clan.For xampl,w must wash our cloths whn thy ar dirty.W should not littr wast things about,and draw on th wall.W mustnt spit in public or cut down trs. W should plant mor trs around our nighbourhood.W should pick th rubbish up and throw thm into th dustbin whn w s thm. W must mak our world mor and mor bautiful!
