可持续发展不仅仅是一个流行词，更是我们对后代的责任。
Sustainability isn't just a buzzword; it's our responsibility to future generations.
快乐有益于身体，但悲伤才能发展心灵的力量。
The real challenge is to create something that has meaning beyond its function.
译文：不管是贫穷还是富有，该欢乐高兴就要尽情欢乐，不懂得尽情欢乐的人是痴人。赏析：人生得意须尽欢，该高兴时要放开玩耍，该行乐时就要尽情享受。我们要做生活的主人，不做生活的奴隶。
