Courtesy costs nothing. Lower the toilet seat after use. Let the people in the elevator exit before you enter. Return shopping carts to their designated areas. When you borrow something， return it better shape (filled up， cleaned) than when you got it.
礼貌，并不需要花钱。用完马桶后，把马桶盖放下；上电梯时，耐心等别人出来再进去；把购物车放回指定区域；在借东西时，归还时要东西的状态要比你借的时候还要好（例如给车加满油、把物品清理干净）。
Every tree we plant today is a promise to tomorrow.
死者并非沉默。他们只是在等待被倾听。
Every small step toward sustainability compounds into a wave of global impact.
写作是对沉默的反抗。
在这个世界上，没有人能使你倒下，假如你自己的信念还站立的话。
强调团队合作在盗墓活动中的重要性。
