Wheat breeding should not only aim for high yield but also disease and stress resistance.
释义:不考虑在安逸的环境中要想到危难,用节俭来戒除奢侈,不使自己的道德处于深厚的境界,不能使自己的情欲战胜物质欲望,这就像砍伐树木的根却想要树木长得茂盛,堵塞水的源头却想要水流得长远一样荒谬。 
唯一的好是知识,唯一的恶是无知。
Many will call me an adventurer, and that I am...only one of a different sort: one who risks his skin to prove his truths.
