The other day, some of my classmates and I took a bicycle trip along the “Renmin Road”, where was specially built for people to relax ourselves. The scenery along the road was fascinating, with trees, flowers, hills and lakes on both side. We stopped by a lake for a rest, where a good many of people were playing happily. But something unpleasant catch our attention, There was rubbish here or there, and there were many plastic bags and bottles floated on the surface of the lake. Such beautiful place was so serious polluted. What a shame! In the end, we couldn't help collecting the rubbish after we left.
