事实是：自然界正在变化。而我们完全依赖那个世界。它提供我们的食物、水和空气。它是我们拥有的最宝贵的东西，我们需要捍卫它。
The truth is: the natural world is changing. And we are totally dependent on that world. It provides our food, water and air. It is the most precious thing we have and we need to defend it.

旋风不能奏出动听的音乐；心灵手巧的妇人未必能够主持好饮食家务；（只会）做文章的读书人不能够治理好国家。
"The greatest enemy of love is not hate, but indifference."
Sustainability starts with small steps, but requires big vision.
译文：做事的时候一定要多替别人着想，读书时一定要切实地下足功夫。赏析：为人处事不能自私自利，不能只顾自己安逸舒适，而要学会换位思考，只有这样，身边才有很多人尊重我们。读书须用功，一字值千金。读书学习要甘于忍受寂寞，才能学有所成。
