笛卡尔曾经说过：“Cogito, ergo sum.”这句美丽的拉丁语的意思是我思故我在。为什么说它是一句伟大的话呢？因为笛卡尔在说这句话的时候已经预料到有许多人会指责这句话的正确性。当然，中国人是他没有想到的。

好了，为什么说它是正确的呢？首先，我们要弄清楚政治课上老师是如何否定这句话的。我猜全中国的老师都会用如下理论反驳它：“我思故我在，难道自己思考就存在，不思考就不存在了吗？这真是谬论，唯心主义！”然而，当有脑子的人仔细想一下就会发现这种逻辑的明显漏洞。各位同学们，你们，包括我，都接受过高中教育吧？都上过数学课吧？数学课中曾经教过我们什么？你还记得吗？逻辑学！

一个命题的反命题一定正确吗？一个命题的逆命题一定正确吗？到底一个命题的什么命题一定正确呢？同学们，你们需要知道这个问题的答案以证明自己的脑子比一颗葡萄还要大！那就是：一个命题的逆反命题永远正确。那么，我思故我在的逆反命题是什么呢？那就是我不在所以我不思，也就是死人无法思考。这句话对吗？看在上帝慷慨地给予我们每一个人以灵魂的份儿上，这句话对吗？它无比正确。

O！你难道对宗教孕育了科学感到诧异吗？你难道对宗教孕育了大学感到羞耻吗？你难道对上帝孕育了一切感到不屑吗？你难道对美本身就是一种美德和目标表示赞同吗？你知道什么是形而上学吗？你知道为什么有人要求你反对它吗？O！难道比我们领先数百年的欧洲人都是傻子吗？难道那位安详地死在自己的早餐桌旁的哲学家是傻子吗？难道高喊“最后一个基督徒已经在十字架上死去”的尼采是疯子吗？虽然他忘了还有斯宾诺莎。

致维纽斯•阿西纳

维纽斯，你出发时我已再三嘱咐，
你要把这几册封好的颂诗交给奥古斯都，
如果他健康、快乐，而且……对了，如果他向你索要它们。
照我说的去做，别因为你热心过度、操之过急，
反而害我错失良机。
如果三册微薄的书令你双肋发疼，那就干脆扔掉吧：
别像头犟驴似的，把鞍囊砰地摔在奥古斯都的脚下，
否则你家族的名字，阿西纳
就会传为全镇的笑料，在你耳里嗡嗡鸣响。
勇敢地翻山越谷，
横过溪流，涉过泥淖。当你度尽难关，终于
抵达目的地，请以正确的姿势拿好你的书包。
别将包袱吊在臂下，像一个农民
手拎着一只羊羔，或者像舞台上的皮丽娅，
还藏着偷来的羊毛球，却已醉得东倒西歪；
或者像一个穷汉，受邀到本区政治领袖家里吃饭，
把便鞋和羊毛帽往肘上一绕就跑来了。
别停下来，对你碰到的每个人说你忙得一身大汗，
是给人送诗，这些诗定会吸引恺撒的眼睛和耳朵。
好啦，你已经听我叨絮过这些紧急的指示，别停！
快去。再见。别绊倒了。书别掉了！

I would like to introduce you one of my favorite works: Tools And Other Works. I created it by color pencils because I always enjoy using pencils to do any job. As you can see, there are four objects on the drawing: a dividers, a plant, a letter β and a piece of work, showing the innate structure of eyes and floaters in eyes. Actually, I created this drawing because I was inspired by Renaissance and Leonardo da Vinci, a genius during 16^th century.

Particularly absorbed in the history of Renaissance in Grade Ten, I realized that people in Italy started to combine science and art in the beginning of 15^th century and new spirit, namely the right to self-create and self-appreciate life, was born. This is my background. Now let’s turn to the drawing.

The letter β represents not only the advance of printing in 15^th century in Germany, but also the explosive spread of knowledge and methods about how to deal with natural science. Personally, I was greatly surprised and attracted by the first sight on a photograph of a page from Gutenberg Bible. Similarly, the paper and the dividers also show that anatomy became more and more important at that time, for the reason indicated by the plant. I idealize the image of the plant to give it the connotation in not only the field of botany but also of decoration. Plant, on one hand, was a subject which was easy to study because of its relative stability. On the other hand, different kinds of plants also inspired many architects to design the decorations of significant public facilities. In addition, in support of the development of art, most artists were also anatomists in Renaissance. They got (in some cases, stole) the bodies and dissected them in order to gain the first-hand information about human body. Correspondingly, you can see an imagination for the dissection and analyses about eyes showing on the brown paper. Since you have already been familiar with the subjects on the drawing, I also want to tell you my feeling about the overall impression by presenting them together. Having completed the drawing, I started to view it for some emotions. At the first sight, I felt a little weird because these subjects were seemingly independent. However, once I had realized their essential relationship (as mentioned above), I felt an influx of intricacy and novelty in my mind. And I knew that my original goal, namely to evoke a sense of deep history by conveying a set of specific subjects, had reached.

Sesame Street is an American educational children's television series and a pioneer of the contemporary educational television standard, combining both education and entertainment. Sesame Street is well known for its Muppets characters created by Jim Henson. It premiered on November 10, 1969, and is the longest running children's program on US television.^[1] The show is produced in the United States by the non-profit organization Sesame Workshop, formerly known as the Children's Television Workshop (CTW), founded by Joan Ganz Cooney and Ralph Rogers.

As author Malcolm Gladwell has stated, "Sesame Street was built around a single, breakthrough insight: that if you can hold the attention of children, you can educate them".^[15] Sesame Street was the first children's show that structured each episode and made "small but critical adjustments" to each segment to capture children's attention long enough to teach them something.^[16]

Sesame Street uses a combination of animation, puppets, and live actors to stimulate young children's minds, improve their letter and word recognition, basic arithmetic, geometric forms, classification, simple problem solving, and socialization by showing children or people in their everyday lives. Since the show's inception, other instructional goals have been basic life skills, such as how to cross the street safely, proper hygiene, healthy eating habits, and social skills; in addition, real-world situations are taught, such as death, divorce, pregnancy and birth, adoption, and even all of the human emotions such as happiness, love, anger, fear, sadness, and hatred. Also, recently, the Sesame Street Muppets discussed the late-2000s recession with their most recent prime-time special Families Stand Together: Feeling Secure in Tough Times.

Coordinating "the clever use of Muppets and animation" with educational curriculum required what the CTW researchers called "careful thought"^[17] and influenced the show's structure. For example, they had to decide how to distribute the letters of the alphabet throughout each 130-episode season.------From Wikipedia, the free encyclopedia
