我以以《登高》為例,引導(dǎo)學(xué)生進行意象分析,感悟意境美。古人云“立象以盡意”“古詩之妙,專求意象”意象是詩人情感的載體,是詩歌的靈魂。引導(dǎo)學(xué)生張開聯(lián)想和想象的翅膀去感受,去體驗是意象,詩歌鑒賞的關(guān)鍵。科林伍德說“真正藝術(shù)的作品,不是看見的,也不是聽到的,而是想象中的某種東西。”詩人通過想象創(chuàng)造出詩的形象,我們讀者通過想象豐富地再現(xiàn)詩人創(chuàng)造的形象。而感受體驗則是以全部身心投入作品,心靈與心靈相溝通,感情與感情相交流,對詩人的想象活動進行再經(jīng)歷和再體驗。因此,在引導(dǎo)意象解讀中,我先讓學(xué)生點擊這一個,就是通過抓修飾詞、依據(jù)感情基調(diào)、展開想象具體分析本詩中每個意象的情感意蘊和審美意蘊,使學(xué)生明白意象在每首詩中的獨特性。
說教材A.教材簡析《琵琶行(并序)》是人教版《普通高中課程標(biāo)準(zhǔn)實驗教科書語文》必修3第二單元的一篇講讀課文。本單元學(xué)習(xí)的是唐代詩歌,共七首詩?!杜眯校ú⑿颍肥翘拼F(xiàn)實主義詩人白居易寫的一首歌行體長篇敘事詩,是我國古代敘事詩和音樂詩中的“千古絕喝”。詩歌主題鮮明、人物形象生動,抒情真切細膩,具有深刻的思想內(nèi)容和卓越的藝術(shù)技巧。B.教學(xué)目標(biāo)《全日制普通高中高級中學(xué)語文教學(xué)大綱》明確要求我們:在閱讀教學(xué)過程中要引導(dǎo)學(xué)生“感受文學(xué)形象,品味文學(xué)作品的語言和藝術(shù)技巧,初步鑒賞文學(xué)作品”。而本單元的教學(xué)要求是培養(yǎng)學(xué)生詩歌鑒賞的能力。根據(jù)教學(xué)大綱和單元教學(xué)要求,結(jié)合本課特點,我制定本課的教學(xué)目標(biāo)是:1.知識目標(biāo):了解文學(xué)常識;積累重點文言實詞;品味主旨句“同是天涯淪落人,相逢何必曾相識”的內(nèi)涵;感知作者把音樂描寫與聽者、演奏者的感情融為一體的寫作特點。
(1)“問君西游何時還……使人聽此凋朱顏?!痹婎}下未注明送何人入蜀,所以這里的“問君”無妨假定實有其人,可以讀得親切一些。將行而問“何時還”,已有不可行之意,重音要落在“不可攀”三字上,當(dāng)用勸說的語氣讀。以下四句借鳥聲渲染旅途中悲涼凄清的氛圍,讀時要放低聲調(diào),有干里孤身之感,至“愁空山”徐徐而上。然后用感喟的語調(diào)讀主旨句,至“凋朱顏”略作一頓,以示意猶未盡。(2)“連峰去天不盈尺……胡為乎來哉!”仍是說不可行,但內(nèi)容加深了一層,因為說的是蜀道的險惡。前四句不是純客觀的描寫,讀時須設(shè)想這是旅游者攀援于“連峰”“絕壁”之上置身于“飛湍瀑流”之間,要使聽者感到驚心動魄。讀后可作稍長停頓,再用“其險也如此”緩緩收住。末句是詩人借用蜀人的口氣,對歷險而來的游者深表嘆息——“胡為乎來哉”不是詢問,當(dāng)用降調(diào)讀,暗含“何苦而來”之意。
(2)世界觀,人生觀,價值觀是人們文化素養(yǎng)的核心和標(biāo)志。一旦形成就會對人產(chǎn)生深遠持久的影響。(但隨著生活閱歷的變化,人們文化素養(yǎng)的提高,人們的“三觀”會發(fā)生變化。)總之“潛移默化”指每時每刻,不知不覺;是從文化對人影響的過程來看的?!吧钸h持久”指經(jīng)年累月,難以抹去;是從文化對人影響的結(jié)果上說的。3.課堂總結(jié):首先啟動學(xué)生思維,教會學(xué)生把握知識主線,建構(gòu)知識體系,先由學(xué)生進行總結(jié),然后教師進行必要的補充4、布置作業(yè):布置作業(yè)。運用文化對人的影響的知識分析“近朱者赤,近墨者黑”,并且應(yīng)該如何處理朋友之間的關(guān)系。設(shè)計這個作業(yè)的意圖是既讓學(xué)生靈活運用所學(xué)知識,同時又讓學(xué)生回歸生活,如何處理朋友之間的關(guān)系。5、板書設(shè)計遵循板書設(shè)計的實用性、直觀性的原則,根據(jù)本課的教材特點,我采用結(jié)構(gòu)式板書,這樣設(shè)計比較直觀、系統(tǒng),以便于學(xué)生能夠系統(tǒng)把握和理解知識。
解析:材料是講學(xué)習(xí)型社會所產(chǎn)生的影響,A項觀點錯誤,在當(dāng)前和今后相當(dāng)長的時間里,學(xué)校教育仍然是人們獲得知識的最重要的途徑。B項觀點錯誤,終身學(xué)習(xí)只是成就人生目的的手段、途徑,而不是目的本身。D項說法錯誤,當(dāng)前我國社會的中心工作是經(jīng)濟建設(shè)。二、問答題5.材料一:日本是公認(rèn)的漫畫大國,日本的動漫產(chǎn)業(yè)產(chǎn)值每年230萬億日元,成為日本的第二大支柱產(chǎn)業(yè)。在日本,漫畫比電影、小說有時甚至比電視或音樂更受歡迎。日本漫畫的熱潮還席卷了世界:日本每年出口到美國的卡通片價值就達5 000億日元,是日本對美國鋼鐵出口金額的4倍;漫畫中的人物被迅速復(fù)制成電子游戲、卡通片及真人演出的節(jié)目。原來只是閑暇時候消遣的漫畫,正飛速滲透到人們的生活中。值得警惕的是,除了催人奮進的精華之外,日本漫畫中也存在暴力、色情、扭曲歷史等諸多糟粕,對缺乏辨別能力的青少年產(chǎn)生了許多不良影響,更引發(fā)了一系列深刻的社會問題。
(1)文化與經(jīng)濟、政治在經(jīng)濟基礎(chǔ)上相互影響。①經(jīng)濟、政治和文化是社會生活的三個基本領(lǐng)域。其中,經(jīng)濟是基礎(chǔ),政治是經(jīng)濟的集中表現(xiàn),文化是經(jīng)濟和政治的反映。一定的文化由一定的經(jīng)濟、政治所決定,又反作用于一定的政治、經(jīng)濟,給予政治、經(jīng)濟以重大影響。②經(jīng)濟發(fā)展是文化發(fā)展的基礎(chǔ)。但這并不意味著文化的發(fā)展始終與經(jīng)濟的發(fā)展亦步亦趨。如同不能簡單地把精神文明看作是物質(zhì)文明的派生物和附屬品一樣,也不能簡單地認(rèn)為文化是經(jīng)濟、政治的派生物和附屬品。文化有其自身的傳承性和相對的獨立性。那種認(rèn)為只要物質(zhì)條件好了,精神文化自然而然地就會好起來,物質(zhì)條件差一點,精神文化就不可能搞好的觀點,不符合歷史發(fā)展的事實,是不正確的。③掀開歷史的畫卷,文化既有古今和地域之別,又有先進與落后、腐朽之分。不同的文化,對經(jīng)濟、政治的影響不同,對社會發(fā)展的作用也不同。不同民族的文化,影響不同民族和國家各具特色的發(fā)展道路。
(二)講授新課:1、講授重點:文化與經(jīng)濟、政治的關(guān)系。我首先帶領(lǐng)學(xué)生分析課本上的活動探究,了解日常生活中的常見活動,讓學(xué)生們觀看視頻材料幫助學(xué)生對文化活動、經(jīng)濟活動、政治活動進行辨別和分類。然后讓學(xué)生們舉例說明,綜合探究,最后通過集體討論得出文化與經(jīng)濟政治的關(guān)系:經(jīng)濟是基礎(chǔ),政治是經(jīng)濟的集中表現(xiàn),文化是經(jīng)濟和政治的反映,一定的文化由一定的經(jīng)濟和政治決定,又反作用于政治和經(jīng)濟。這個問題是本課重點。要引導(dǎo)學(xué)生循序漸進,集體討論,得出結(jié)論。2、突破難點:(1)文化與經(jīng)濟政治相互交融,在時代發(fā)展的進程中。首先播放上海世博會視頻,讓學(xué)生體會文化、經(jīng)濟、政治活動,另外我會引導(dǎo)學(xué)生積極舉生活中的事例,來說明問題,讓學(xué)生學(xué)會舉一反三,充分理解這一知識,讓學(xué)生明白文化與經(jīng)濟、政治的聯(lián)系,讓學(xué)生清楚文化滲透的力量有多大,幫助學(xué)生樹立反對文化霸權(quán)主義的意識。
3、文化的力量。為了使學(xué)生能辨證地分析文化的力量,我設(shè)計了兩個問題進行探討:(1)是不是任何文化都能起促進作用?(2)你在聽或唱國歌時感受到一種什么樣的力量?這樣,學(xué)生在對比中學(xué)會辨證地分析文化的力量——先進的、健康的文化能促進社會發(fā)展和個人成長;落后的、腐朽的文化則阻礙社會發(fā)展和個人成長。同時還能提高學(xué)生的文化賞析能力,從而引導(dǎo)學(xué)生裝自覺參加健康有益的文化活動,抵制不良文化的影響,投身到社會主義精神文明建設(shè)中去。關(guān)于課堂練習(xí),我準(zhǔn)備了5個針對性比較強的選擇題,從而加深鞏固本框題的重難點知識。最后,播放歌曲《走進新時代》,展示本課知識結(jié)構(gòu),指出本框題需重點掌握的問題,結(jié)束本課教學(xué)。課后作業(yè),我設(shè)計了這樣一個辨析的題目:文化是人們創(chuàng)造的全部財富的總和,它是人類特有的現(xiàn)象。
一. 教材分析1. 本單元的中心話題是“計算機(Computers)”,內(nèi)容涉及計算機的發(fā)展歷史,計算機的應(yīng)用等。本節(jié)課是該單元的第一課時,我將Warming up, Pre-reading and Comprehending這四部分整合為一節(jié)精讀課。其中。Reading部分是題為WHO AM I?的文章,以第一人稱的擬人手法介紹了計算機發(fā)長演變的歷史和計算機在各個領(lǐng)域的應(yīng)用,其主旨是表達計算機的發(fā)展變化之快以及在生活中用途之廣。而Warming up部分以圖片的形式展現(xiàn)了計算機的發(fā)展歷程;Pre-reading中的問題和排序分別是為了預(yù)測語篇的內(nèi)容和測試學(xué)生對計算機歷史了解的情況;Comprehending則通過各項練習(xí)訓(xùn)練學(xué)生的閱讀技能,從而加深對文章的理解。可見這幾部分是一個有機的整體。2. 教學(xué)目標(biāo):1) 語言目標(biāo):重點詞匯及短語:abacus, calculate, calculator, PC, laptop, PDA, robot, analytical, technological, universal, mathematical, artificial, intelligent, network, explore, in common, as a result.重點句子:a. My real father was Alan Turing, who in 1963 wrote a book to describe how computers could be made to work, and build a “universal machine” to solve any mathematical problem.
When it comes to the students’ studying methods, I'd like to introduce my Ss first. The Ss have a good command of basic language points. They’re interested in learning English, and they take an active part in English class, so they will have fun in autonomous, cooperative and inquiry learning. I will just serve as a guide, showing them the way to explore how to make more progress in their English learning.Now it’s time for the most important stage of this lesson. My teaching procedures are arranged as follows:Step1.Leading-in (3 minute)Play a video of a wide variety of wildlife to introduce my topic. Step2. Speaking (12 minutes)We will use our textbook Page25. Let the Ss fast read the short paragraph to warm up. Ask them to talk about the report on some endangered wildlife in China with the dialogue patterns on the screen. Lastly, I will invite some groups to demonstrate their dialogues about saving wildlife in China.Step3.English play (3 minutes)Watch another video in praise of their excellent performance just now. It’s about Jack Chen’s(成龍)and Yang Ziqiong’s wildlife protection.Step4. Listening (twice 13 minutes)This time, I’ll ask the Ss to fill in the blanks of the monologue of the 2 movie stars above. Step5.Discussion (3 minutes)Which would you like to choose to wear, clothes made of cotton, artificial leather or animal skins? Why ?Step6. Summary (3 minutes)1. If there were no wildlife, there wouldn’t exist human beings. If the buying stops, the killing can, too.2. Animals are our friends. To love animals is to love ourselves. Stop hunting, killing and destroying wildlife.3. Let’s live in harmony with all the living things in the world. Step7. Music appreciation (3 minutes)Let the Ss appreciate the song Earth Song by Michael Jackson. Last but not the least, I will show you my blackboard design.
Then I would ask them to think of a funny English or Chinese and tell it to partners. While telling stories, they can use expressions and some acting to help make the story funny. 5 minutes would be given to do this.Those stories they told there will be the material for their writing. Soletting them tell it at first is helpful. And they can make a difference between telling a funny story and writing it down. Generally speaking, it is difficult forstudents to write well because they don’t know what to write and how to write. Asking them to tell their own stories at first can help them come up with what to write.After their telling, I would invite someone to share his/her story with all of us and I would write it down on the blackboard.This example story would be used as a sample to illustrate the format of funny story. Different from a story from teacher or textbook, a story from students can obviously become a interesting material to draw students’ attention.Then I would ask the whole class to put this story into several parts. It might be a little bit difficult for them. So I would ask them to find out whether all the sentences are necessary. After delete some sentences, there are 6 sentences left behind. Then they can easily put them into three parts. After interaction with students, I would teach them the right terms for each part and conclude the format of funny story.This step is the key and difficult point in my lesson. So I mainly usetask-based teaching method in this part and the task for students was divided into several stages. With the separated difficult level, students can find there are usually three parts in writing. They can also learn to write without the unnecessary parts in the process of analyzing. And then I wouldn’t rush to tell them the right terms to them directly. Instead, I would ask them to name them by their own. A confused mind is better for acquiring knowledge.While-writing:Then I would give students 7 minutes to write down this story, without other requirements.With all the preparations in pre-writing, students’ difficulties were cleared. So it would be much easier for them to write down the story within 7 minutes. There are no other requirements because students’ first writing is actually a drafting. It would be revise and edit several times later. Writing, as a skill
Good afternoon, teachers, It’s my great pleasure to be here sharing my lesson with you.The content of my lesson is Senior English Book 3 Unit 5 Canada —— “The true North”.I’ll be ready to begin this lesson from five parts. Analysis of the teaching material,the teaching methods,the studying methods, the teaching procedure,and Blackboard design.First, let me talk about the teaching material.Part 1 Teaching Material:This unit is about the introduction of Canada. By studying of this unit,we’ll enable the students to learn the geography, population, main cities, and natural beauty, natural resources of Canada. Through the training of the unit, it also requires students to learn some Language skills such as the expressions of position and emotions.So it plays an important part in the English teaching in this book.After studying the teaching material and analyzing the rule of children’s growing of mind,I think the teaching aims are the followings:1.Knowledge objects:(1) make the students learn some new words and phrases(2) make the students understand the content of the lesson.2.Ability objects:(1)To develop the Ss’ abilities of listening, speaking, reading and writing. Especially reading and speaking ability.(2) learn to talk about the characters of Canada in English(3)To train the Ss’ ability of working in pairs.3.Emotion objects:(1)Enable students to understand the characters of Canada..(2)Stimulate Ss to work hard to make China stronger.Part 2 Teaching Methods:I think helping students learn to master new words and phrases and improve the students’ reading and speaking ability is import and the difficult.According to the analysis of the teaching material and the import points and the difficult points,I will use the following teaching methods : question-guiding approach; fast-reading and careful reading; multi-media teaching methods; discussion
The oldest and the most popular park in the worldenjoy the exciting activities thereget close to the life-size cartoon characters like Mickey Mouse and Donald Duck Step 3 Pre-reading1.What do you suppose a theme park is ?2.What do you think you can see in a theme park?(1.It is a kind of amusement park which has a certain theme – that the whole park is based on. 2.buildings, castles, statues, rare animals and birds, and so on.) Step 4 Reading ----- Theme Parks –---- Fun and More Than Fun1.Predict : Read the title and the pictures on P. 34 and PredictWhat is the meaning of the title “Theme Park – Fun and more than fun”?(The title means that theme parks are fun to visit, but that they can also be educational and can offer useful information.)2.Skimming Fast read and answer:What activities can we take in a theme park?Amusement park: Bumper car Merry-go-round slide bungee jumping Free-fall rides Horror films Pirate ship Ferris wheel roller coaster3.Scanning Read again and you will find various theme parks are mentioned in the passage . Then what are they ?Theme parks: Sports theme park History theme park Culture theme park Marine or Ocean theme Park Future park Science theme park Disneyland4.Careful reading and find the main idea of each paragraph:THEME PARKS---- entertaining/ educationalPara.1 Traditional parks are places to go for relaxation and to have time away from our busy lives.Para.2 Theme parks are different They’re large and full of things to do, see and buy.Para.3 Theme parks are built around a single idea or theme. One example is a sports park.Para.4 Another kind of theme park is historical more and cultural and can be educational.Para.5 Disneylandwas the first theme park. It is based on the fantasy life and characters of Disney’s films.Para.6 Some examples of educational theme parks include sea world parks and science parks.
Language learning needs a context, which can help the learners to understand the language and then can product comprehensible output, so computer has the advantages to make the materials attractive.Part 3 Learning MethodsTask-based, self-dependent and cooperative learningPart 4 Teaching ProcedureStep One Lead-in“Interest is the best teacher.” Therefore, at the very beginning of the class, I should spark the students’ mind to focus on the centre topic “the band”. I’ll show some pictures of food to attract their attention and then bring some questions.Question:What kind of food they like?What should go into a good meal?The answers must relate to the diet. After this, the students will be eager to know something about a balance diet and this is the very time to naturally lead the class into Step 2Step 2 Reading for information: skimming and scanning In this step, I use Task-based Language Teaching method, which can give students a clear and specific purpose while skimming and scanning the context.Task 1 General ideaThe students will be asked to just glance at the title and the pictures of the passage, and then guess what they will read in the text. And they’ll be divided into groups of four to have a discussion.The purpose is to inspire the students to read actively, not passively. In addition, the task is to develop the students’ reading skill by making prediction and to encourage the students to express their thoughts in English and cooperate with each other.Task 2 Main idea of each paragraphCooperative learning can raise the students’ interest and create an atmosphere of achievement. Based on this theory, I divide the whole class into 4 groups to skim the whole text and get the main idea of each paragraph.
Knowledge objectives:(1) to make Ss grasp the usage of words, expressions and sentence structures: statistics, struggle, thanks to, rid of, some patterns for persuasion, the “ing” form as subject and object;(2)to use learnt knowledge to persuade sb.Ability objectives:(1) to develop Ss’ reading skills(skimming, scanning, word guessing);(2) to improve Ss’ speaking, communicating and cooperating skills.Emotional objectives:to make Ss know the contribution of Yuan,and learn his spirit and his simple life time.Teaching important and difficult points:(1) some words, expressions and sentence structures mentioned above;(2)the content of the text;(3)training their reading and speaking skills.Teaching methods: CLT, TBLT,QT.Learning strategies: CLS, QLS, TBLS.Teaching procedures:Step 1 lead-in: (1) teacher plays a piece of recent news from CCTV about the harvest of the super hybrid rice, and ask students whether they know Yuan or not, and talk about him and his contribution.(2)Brain storm: let Ss describe Yuan in their minds including his appearance, his living condition and so on.Step 2 fast reading tasks:(1)teacher introduces Yuan and super hybrid rice(2)make Ss read the text as fast as possible with questions. Such as: what’s the general ideaof this passage? What’s Yuan’ dream? (skimming and scanning skill)Step 3 intensive reading tasks(1)let Ss read the text silently, find topic sentence of each paragraph and draw the difficult sentences and the knowledge what they don’t understand.(words guessing)(2)teacher and Ss talk about the important words, expressions and sentences together, and ask Ss to retell the content of the text.(summarizing and paraphrasing)(3)teacher summarize this part.(4) read again following the courseware.
基于以上分析,為使本堂課圍繞重點、突破難點,同時讓學(xué)生在課堂教學(xué)中能力得到提高,我設(shè)計如下教學(xué)過程。(一)創(chuàng)設(shè)情景認(rèn)識形變由同學(xué)們已有的形變知識入手,引入新課。教師演示:①彈簧的壓縮形變;②彈簧的拉伸形變③視頻播放:竹竿形變、鋼絲的扭轉(zhuǎn)形變。得出形變的概念及各類形變。[設(shè)計意圖:我從生活情景中引入新課,是為了激發(fā)學(xué)生的好奇心,為學(xué)生學(xué)習(xí)重點和難點內(nèi)容作鋪墊。]設(shè)問:摩天大樓在風(fēng)的吹拂下會不會擺動,發(fā)生形變嗎?演示微小形變放大實驗:由于這種形變不容易觀察,會使學(xué)生產(chǎn)生疑問:到底有沒有發(fā)生形變?解決的辦法是微小形變的演示實驗。為什么光點會往下移?讓學(xué)生帶著問題思考后得出結(jié)論:是由于桌面發(fā)生了形變,但是形變不明顯。為后面解決壓力和支持力都是彈力做好鋪墊。[設(shè)計意圖:使學(xué)生知道“放大”是一種科學(xué)探究的方法。]
通過這個示例呢,我們可以得到解決向心力問題的一般的步驟,確定對象,找出軌跡,找出圓心,然后進行受力分析,讓同學(xué)們參考這樣的步驟,逐步的解決圓周運動的問題,對于變速圓周運動,我通過鏈球運動進行引入,這里是一個鏈球運動的視頻,在同學(xué)們觀看視頻之前,我給同學(xué)們提出問題,鏈球收到繩子的拉力,做的是勻速圓周運動嗎? 然后再課堂上我們再做一個小實驗, 我們可以通過改變拉線的方式來調(diào)節(jié)小球的速度大小嗎? 那么對小球,做加速圓周運動,進行受力分析,我們可以看到,小球做加速運動時,他所受到的力,并不是嚴(yán)格通過軌跡的圓心,在進行分析的時候,特別強調(diào),小桶所受力的切線方向分力,和法線方向分力,切線方向分力,改變小球運動速度大小,法線方向分力,改變了小球運動的方向,法線方向的分力,在這里就是向心力,產(chǎn)生了向心加速度,通過這樣一個例子進行分析,同學(xué)們是比較容易理解的,
二、學(xué)情分析:學(xué)生目前對形變和彈力有一定的感性認(rèn)識但是不夠深入;知道支持力、壓力都是彈力,但是不能夠概括產(chǎn)生的原因。理性思維還沒有達到一定的層次,要想理解彈力這一抽象概念還有一定困難。因此我采取引導(dǎo)、啟發(fā)的教學(xué)方式。
知識目標(biāo)1.了解傳統(tǒng)工業(yè)區(qū)的分布、條件和工業(yè)部門。2.掌握傳統(tǒng)的魯爾工業(yè)區(qū)優(yōu)越的區(qū)位條件,了解它的衰落原因及其綜合整治途徑。能力目標(biāo)1.讀圖分析礦產(chǎn)資源與工業(yè)部門之間的聯(lián)系,培養(yǎng)學(xué)生的地理思維能力、綜合分析能力,明確工業(yè)生產(chǎn)也應(yīng)因地制宜。2.聯(lián)系實際,了解當(dāng)?shù)貍鹘y(tǒng)工業(yè)發(fā)展?fàn)顩r,為適應(yīng)當(dāng)今世界經(jīng)濟發(fā)展?fàn)顩r,應(yīng)有哪些改善措施,培養(yǎng)學(xué)生的創(chuàng)新能力。德育目標(biāo)1.通過了解魯爾區(qū)的發(fā)展變化,用發(fā)展的觀點看待傳統(tǒng)工業(yè)區(qū)的改造,適應(yīng)世界發(fā)展潮流。2.中國已經(jīng)“入世”,我們應(yīng)用辯證唯物主義觀點分析我國傳統(tǒng)工業(yè)今后遇到的機遇和挑戰(zhàn)。
5.循環(huán)經(jīng)濟當(dāng)前,發(fā)展循環(huán)經(jīng)濟和知識經(jīng)濟已成為國際社會的兩大趨勢,有的發(fā)達國家甚至以立法的方式加以推進。循環(huán)經(jīng)濟本質(zhì)上是一種生態(tài)經(jīng)濟,它要求運用生態(tài)學(xué)規(guī)律而不是機械的規(guī)律來指導(dǎo)人類社會的經(jīng)濟活動,減量化、再利用和資源化是其三大原則。傳統(tǒng)經(jīng)濟是一種“資源——產(chǎn)品——污染排放”單向流動的線性經(jīng)濟,特征是高開采、低利用、高排放;與之不同,循環(huán)經(jīng)濟倡導(dǎo)的是一種與環(huán)境和諧的經(jīng)濟發(fā)展模式,它要求把經(jīng)濟活動組織成一個“資源——產(chǎn)品——再生資源”的反饋式流程,特征是低開采、高利用、低排放。目前,我國已經(jīng)把發(fā)展循環(huán)經(jīng)濟作為編制“十一五”規(guī)劃的重要指導(dǎo)原則。6.當(dāng)心被優(yōu)勢“絆倒”有三個旅行者同時住進一家旅店,早上同時出門旅游。晚上歸來時,拿傘的人淋得渾身是水,拿拐杖的人跌得滿身是傷,而什么也沒有帶的人卻安然無恙。
