As we all know, the environment around us is getting worse and worse. In some places we can’t see fish 　 46 in the river or trees on the hills. Some people even have no clean waster to drink.

　　 Recently, a new lifestyle called low-carbon life(低碳生活) is 　 47　 every corner of our country. The meanings of low-carbon are 　 48　 energy and no waste. It is such an important project that I can’t wait 　 49　 my ideas on how to promote( 促进、发扬) it.

　　 First, we should 　 50　 a no-car day every week in our school. Because cars not only cause serious air pollution but also waste energy. 　 51　 the no-car day, neither students 　 52　 teachers are allowed to drive to school. At the same time, just walk or run. Use our 　 53　 and enjoy the fun.

　　 Second, we had better not use plastic bags 　 54　 . No one can stand the “white pollution”, 　 55　 it is wise to use cloth bags which can 　 56　 again and again.

　 　 57　 , one thing 　 58　 we should keep in mind is that every big thing comes from the small details(细目、细节). So, as students, we ought to turn 　 59　 the lights the moment we leave, use 　 60　 sides of the paper, and reuse our textbooks and so on.

　　 All in all, it weights 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.
