　　It was already late when we started for the next town,which according to the _1_was about fifteen miles away on the other side of the hill.There we felt_2_that we would find a bed for the night.Soon _3_fell after we left the village,but _4_,we met no one as we drove fast along the narrow road that _5_to the hill.As our car climbed _6_,it became colder and the rain began to fall,making it difficult to see the road.
　　After we had travelled for about twenty miles,there was still no_7_of the town which was marked on the map,we were beginning to get _8_.Then,the car suddenly stopped .A quick examination showed that we had used up the gas.Although we had little food with us,we diceded to spend the night in the car.
　　Our meal was soon _9_, and then I tried to go to sleep at once,but John,who was a poor sleeper,got out of the car after a few minutes and went for a walk up the hill.Soon he found,in the valley bellow,the _10_of the town we were looking for.We at once pushed the car to the top of the hill.In less than a quarter of an hour ,we were in the town.
　

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.
