1.Recently,a new lifestyle called low carbon(碳)life is spreading every corner of our country.The meanings of low carbon are low energy and no waste.It is so important a project that I can't wait to express my ideas on how to promote(推动)it.
  First,we should set up a no-car day every week in our school.Because cars not only bring serious air pollution but also waste energy.On the no-car day,neither students nor teachers are allowed to drive to school,just walk or run.Use our legs and enjoy the fun.
  Second,we had better not use plastic bags.No one can stand the"white pollution",so it is wise to use cloth bags which can be used again and again.
  Finally,one thing that we should keep in mind is that every big thing comes from small details(细节).So,as students,we should turn off the lights the moment we leave,use both sides of paper,and reuse our textbooks and so on.
  All in all,it weighs greatly for all of us to put the low carbon lifestyle into practice.Just set our mind to these:no-car days,no plastic bags,and no waste.Let's do it now.
