The truth is rarely pure and never simple.
You build your life around the fact that you are going to die, and then you don’t die.
The world is a book, and those who do not travel read only one page.
Poetry is the language of the soul, spoken in the rhythm of the heart.
Every day is a new opportunity to change your life.
农业的未来在于平衡生产力与环境责任。
数学的力量在于它的抽象性，使我们能够看到不立即显现的模式和联系。
过去是一个影子，总是跟随，但从未追上。
