In some places we cant see fish 1 in the river or trees on the hills. Some people even have no clean water to drink. Recently, a new life style called low carbon（低碳）life is spreading every corner of our country. The meanings of low carbon are 2 energy and no waste. It is such an important project that I cant wait to express my ideas on how to promote it. First, we should 3 a no-car day every week in our school. Because cars not only cause serious air pollution but also waste energy. 4 the no-car day, neither students 5 teachers are allowed to drive to school. Atthe same time, just walk or run. Use ourlegs and enjoy the fun. Second, we had better not use plastic bags 6 . No one can stand the“white pollution”， 7 it is wise to use cloth bags which can be used again and again. 8 ，one thingthat we should keep in mind is that every big thing comes from the small details. So, as students, we ought to turn 9 the lights the moment we leave, use 10 sides of the 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. Lets do it now.( )1.
