Every time when I go home by train, I feel very uncomfortable, because I have to smell the terrible air, people always smoke, making the public place smell bad. Since the motor¹ train operates, I feel so happy, I find the train is very clean, the air smells good, no people smoke in the train. I feel so surprised, this is the ideal² environment for me, in the long journey, all the people are so polite. Smoking³ in the public place should be banned, the bad smell not only makes people sick, but also does harm to their health. In the long journey, people need to keep a good environment, so they have a good mood.

每次当我坐火车回家，我会感到很不舒服，因为我不得不闻到令人讨厌的气味，人们总是吸烟，使得这个公共的地方闻起来不舒服。自从动车开行了以后，我很开心，我发现车上很干净，空气很舒服，没有人在车上吸烟。我很惊奇，这对于我来说是最理想的环境了，在长途中，所有人都很有礼貌。在公共场所吸烟应该禁止，糟糕的气味不仅仅使得人们不舒服，而且有害于人们的健康。在长途中，人们需要一个好的环境，来保持好的心情。
