Example:One day, a poor boy who was trying to pay his way through school by sending newspapers door to door found that he only had one dime(一角）left. He was so hungry that he decided to beg for a meal at the next house.However, he lost his nerve when a lovely young woman opened the door. Instead of a meal he asked for a drink of water. She thought he looked hungry so she brought him a large glass of milk. He drank it slowly, and then asked, “How much do I owe you?” “You don’t owe me anything,” she replied, “Mother has taught me never to accept pay for a kindness.” “Then I thank you from the bottom of my heart.” With these words, Howard Kelly left that house.Years later the woman became badly ill and was finally sent to the hospital in a big city. Dr. Howard Kelly, now famous, was called in. When he heard the name of the town she came from, a strange light filled his eyes. Dressed in his doctor’s clothes, Dr. Kelly went into her room and recognized her at once. From that day on, he gave special attention to her, and decided to do his best to save her life.At last the woman was saved. Dr. Kelly asked the business office to pass the final bill to him. He looked at it and then wrote something on the side. The bill was sent to the woman’s room. She was afraid to open it because she was sure that it would take the rest of her life to pay for it off. Finally she looked, and the note on the side of the bill caught her attention. She read these words: “Paid in full with a glass of milk, Dr. Howard Kelly.” Tear of joy flooded her eyes.

Everybody wants to get wealth.In today’s material world,making money or becoming wealthy symbolizes a person’s success and capability. Many people just make every effort, pay any price to attain greater wealth. With money,they can buy nice, large apartments in nice neighborhood. With money they can own luxurious cars. Wealth seems to bring all happiness in life.But is wealth the only road to happiness? Not really. There are many things in the world, which are beyond the means of money, such as friendship, love, health and knowledge. People are so preoccupied with struggling for money that they have no time or would not take the time to form or maintain friendship. What happiness can they feel living as lonely miserable creatures without love or friends in the world even if they accumulate tremendous wealth?In my opinion, people can’t do anything without money, but money is not everything. What money will bring you depends on your personal belief and goal in life. If you are kind enough to help others, especially the poor, money is a good thing to you. With it, you can do much more for the benefit of people and your country, and it will add to your own happiness. If you want money just for your own needs, you’ll never be satisfied or happy. In a word,you should have money spent for more people. Only then can money be the source of your happiness.Step 8 Homework4 students in a group, one acts Roderick, one Oliver, one servant and the fourth one acts Henry Adams, then listen to the tape, pay more attention to the difference between American English and British English in pronunciation, stress, tone.

不可知論是否認(rèn)人們認(rèn)識(shí)世界或徹底改造世界的可能性的哲學(xué)學(xué)說。此概念首先由英國的赫胥黎(1825—1895)于1869年提出，不可知論的思想在古代就已產(chǎn)生，歐洲近代的主要代表是休謨和康德。其本質(zhì)是把人的感覺看作是主觀和客觀之間的屏障而不是橋梁，不承認(rèn)在感覺之外有確實(shí)可靠的客觀外部世界的存在，不懂得認(rèn)識(shí)過程中本質(zhì)與現(xiàn)象、有限與無限的辯證關(guān)系。對(duì)不可知論最有力的駁斥是實(shí)踐。有時(shí)不可知論一詞也用以專指針對(duì)宗教教義而提出的一種學(xué)說，認(rèn)為上帝是否存在、靈魂是否不朽是不可知的。2．二元論二元論是認(rèn)為世界有兩個(gè)本原的哲學(xué)學(xué)說，與一元論相對(duì)立，它把物質(zhì)和意識(shí)絕對(duì)對(duì)立起來，認(rèn)為物質(zhì)和意識(shí)是兩個(gè)各自獨(dú)立、相互平行發(fā)展著的實(shí)體，誰也不產(chǎn)生誰，誰也不決定誰，都是世界的本原。它的觀點(diǎn)是錯(cuò)誤的：它肯定精神不依賴于物質(zhì)而獨(dú)立存在，這本身就是唯心主義的觀點(diǎn)；它雖然承認(rèn)物質(zhì)是獨(dú)立的本原，但在說明物質(zhì)和精神的關(guān)系時(shí)，又把精神說成是唯一具有能動(dòng)性的力量，必然倒向唯心主義。主要代表人物是法國的笛卡兒和德國的康德。

2．辯證的否定(1)辯證的否定是事物的自我否定。事物內(nèi)部存在著肯定方面和否定方面，它們既對(duì)立又統(tǒng)一。最初，肯定方面處于支配地位，否定方面處于被支配地位。在這種情況下，事物就被肯定著。但是，在矛盾雙方的斗爭(zhēng)中，否定方面總會(huì)由弱變強(qiáng)。一旦否定方面由被支配地位上升為支配地位，事物就轉(zhuǎn)化到了自己的對(duì)立面，實(shí)現(xiàn)了對(duì)事物的否定。事物最終之所以被否定，根源在于事物的內(nèi)部，是事物內(nèi)部的否定因素戰(zhàn)勝了肯定因素。因此，事物的否定是自我否定。(2)辯證的否定是事物發(fā)展的環(huán)節(jié)和聯(lián)系的環(huán)節(jié)。所謂發(fā)展，是指新事物的產(chǎn)生和舊事物的滅亡。而實(shí)現(xiàn)這一過程必須要對(duì)舊事物進(jìn)行否定，否定實(shí)現(xiàn)了事物由舊質(zhì)向新質(zhì)的飛躍。新事物在否定舊事物時(shí)，并不是把舊事物全盤拋棄，一筆勾銷。舊事物是新事物的母體，新事物從舊事物那里脫胎而來，新事物是在批判地繼承舊事物中的一切積極的有生命力的因素的基礎(chǔ)上發(fā)展起來的。這樣，在新舊事物之間就存在著必然的聯(lián)系。

人教版高中政治必修4第五課把握思維的奧妙教案
2．人工智能、信息及其對(duì)意識(shí)論的深化現(xiàn)代科學(xué)的發(fā)展，特別是以信息論、控制論、電子計(jì)算機(jī)科學(xué)和腦科學(xué)相結(jié)合為理論基礎(chǔ)的人工智能技術(shù)的發(fā)展，進(jìn)一步證明了辯證唯物主義關(guān)于物質(zhì)和意識(shí)的相互關(guān)系的原理，也給這種現(xiàn)代唯物主義提出了需要深入探索和解釋的許多哲學(xué)問題。在這些問題之中，人工智能和信息尤為重要。人工智能是相對(duì)于人的自然智能而言的。所謂自然智能，是指人所特有的自覺的意識(shí)能力，特別是抽象思維能力。由于這種能力是人的一種天賦，所以將其稱為人的自然智能。所謂人工智能，則指憑借電子計(jì)算機(jī)所實(shí)現(xiàn)的對(duì)人的某些智能的模擬，通過這種思維模擬，使人的某些智能得以再現(xiàn)和放大。自從電子計(jì)算機(jī)在20世紀(jì)中期問世以來，其作用越來越廣泛，模擬功能越來越強(qiáng)，更新?lián)Q代越來越快，對(duì)生產(chǎn)和社會(huì)生活的影響也越來越大。自50年代中期開始，人工智能便以計(jì)算機(jī)作為主要的支持手段，逐漸發(fā)展成為一門新興的科學(xué)技術(shù)。
- 3．柏拉圖(公元前427一前347)古希臘哲學(xué)家。生于雅典。蘇格拉底的弟子，亞里士多德的老師。他曾在雅典創(chuàng)辦學(xué)園，收徒講學(xué)，逐步建立起歐洲哲學(xué)史上第一個(gè)客觀唯心主義體系。他也是歐洲哲學(xué)史上第一個(gè)有大量著作傳世的哲學(xué)家。他提出世界的本源是“理念”，現(xiàn)實(shí)中的事物都是“理念”的摹本。人的知識(shí)來源于對(duì)“理念”的回憶。柏拉圖的哲學(xué)思想對(duì)后世影響很大，有人說，柏拉圖之后的歐洲哲學(xué)思想都是對(duì)柏拉圖思想的注腳。4．黑格爾(1770—1t53l)19世紀(jì)德國古典哲學(xué)家，客觀唯心主義者、辯證法大師。生于斯圖加特，卒于柏林。出身于官僚家庭。曾在圖賓根神學(xué)院學(xué)習(xí)哲學(xué)和神學(xué)。大學(xué)畢業(yè)后，做過幾年家庭教師。后任報(bào)紙編輯、中學(xué)校長、大學(xué)講師、教授和柏林大學(xué)校長。黑格爾是在法國革命的直接影響下成長起來的，青年時(shí)朝氣蓬勃，非常激進(jìn)。他還深受著名詩人歌德的影響。1818年，他到柏林大學(xué)任教后，公開美化普魯士專制制度，號(hào)召人們同現(xiàn)實(shí)妥協(xié)。

2、理解目標(biāo)（1）發(fā)展的普遍性；（2）事物發(fā)展的道路和方向；事物發(fā)展的形式；3、運(yùn)用目標(biāo)（1）根據(jù)所學(xué)知識(shí)，結(jié)合相關(guān)原理，分析說明自然界、人類社會(huì)是無限發(fā)展的。了解唯物辯證法是關(guān)于世界普遍聯(lián)系的科學(xué)，又是關(guān)于世界永恒發(fā)展的科學(xué)。（2）根據(jù)有關(guān)原理，理解事物發(fā)展的前途是光明的，道路是曲折的，說明新事物必然戰(zhàn)勝舊事物是宇宙間不可抗拒的規(guī)律。（3）結(jié)合古人有關(guān)的名言警句，組織學(xué)生討論生活和學(xué)習(xí)中的具體問題，分析量變和質(zhì)變的辨證統(tǒng)一關(guān)系對(duì)于生活和實(shí)踐的意義。二、能力目標(biāo)1、通過學(xué)習(xí)，培養(yǎng)學(xué)生正確認(rèn)識(shí)事物發(fā)展的方向、發(fā)展的道路和發(fā)展的形式，用發(fā)展的眼光看問題、分析問題的能力。2、使學(xué)生初步具有運(yùn)用科學(xué)發(fā)展觀觀察、分析和處理自然和社會(huì)現(xiàn)象的能力。3、使學(xué)生初步形成正確對(duì)待生活中的失敗與成功、困難挫折與理想目標(biāo)之間關(guān)系的能力。
