特殊的教育体制促使新的一代养成零维的思考方式；点状思维，信息孤岛，死记硬背。我们要从【零维】上升到【一维】的思考方式：线性思维 什么是线性思维： 所谓线性思维，就是将两件事，两个概念，像一条线一样串联起来，彼此关联，相互连接。 我们的学习就是靠连接完成的 ：譬如少儿看图识字， 我们思考问题，也可以靠连接来完成，由A推倒出B，由B联想到C： 比如《论语·子路》中的经典语录： 名不正，则言不顺； 言不顺，则事不成； 事不成，则礼乐不兴； 礼乐不兴，则刑罚不中； 刑罚不中，则民无所措手足。 这个彼此连接，逐步推导的过程，就是线性思维。 线性思维是逻辑思考的基础 如果无法建立事物之间的联系，因果关系，你的思维会变得一片混论。 建立连接的三种方法：演绎法，就是由「因」推导出「果」，由一般推导出特殊的思维方式。演绎法核心思维--三段论：（大前提）所有的人都是要死的（小前提）苏格拉底是人（结论）所以苏格拉底是要死的三段论中5项基本原则：四项错误：一个三段论中，只能有三个不同的概念。有四个，就一定错误。 eg：人已经存在几百万年了；而你没有存在几百万年；所以你不是人。 看上去有3个概念：人，几百...

Dear Optometrist, My name is Robin. Last week i just saw you because of my eyes. I can't see things clearly. Do you remember me? I'm writing to ask you about my treatment, because i think there is still something wrong with my eyes. and the medicine you gave me last week doesn't work well. I always feel light-headed and dizzy and i feel very sleepy after i eat the medication you got me. Now I'm not allowed to drive and work. I think i won't be able to keep my job if i don't start going to wor...
