中文翻译：
保持一个好的心情一辈子陪伴着你的不是名利，也不是青春和容貌，而是你的情绪或精神状态在现代控制着你作为男人的生活，我们的情绪就像在高速公路上来往的汽车一样容易受到邻居的恩惠，孩子的吻，别人的赞扬，就像温暖的阳光这让我们感到欣慰。陌生人说粗话，从商店买的假货，或是开玩笑时说些侮辱性的话，都会让你心情不好，让你心跳加速。好心情让人快乐，精力充沛，富有创造力。
好心情会陪伴你走向成功的殿堂，去爱的殿堂，快乐的生活，我们可以过上更充实的生活，一个更有趣和更有意义的人所以，无论你去哪里或做什么，都要记得保持一个快乐的心情。

每个人都知道有严重的问题，水污染。是的，水污染越来越严重。在河水越来越脏。大多数的鱼都死了，我们不能在水中游泳。
我祖父说，当他很小的时候，河里的水很干净。他经常和他的朋友们在河里游泳。
