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

人教版高中政治必修1市場配置資源說課稿
（2）、市場調(diào)節(jié)存在固有的弊端：自發(fā)性：由于市場調(diào)節(jié)是在價值規(guī)律自發(fā)作用下進行的，在利益驅(qū)動下會產(chǎn)生一些違反市場原則的行為，如制造、銷售假冒偽劣商品，大量排放廢水、廢氣破壞環(huán)境，竊取他人智力成果等等。盲目性：由于人們不可能完全掌握生產(chǎn)各方面信息及其變化趨勢，致使決策帶有一定的盲目性。如某種商品有利可圖則一哄而上，反之則一哄而退，從而造成資源浪費和消費得不到充分滿足。滯后性：由于市場價格的形成和傳遞有一個過程，一旦傳遞到生產(chǎn)經(jīng)營者手中進行生產(chǎn)調(diào)整，就有一個時間差，致使市場調(diào)節(jié)帶有滯后性，成為一種事后調(diào)節(jié)。教師活動：請同學(xué)們想一想，市場的這些弊端和不足，會導(dǎo)致什么后果？（3）、危害教師總結(jié)：資源浪費，經(jīng)濟波動與混亂，分配不公兩極分化等。設(shè)計意圖：通過創(chuàng)設(shè)情景，加深對市場調(diào)節(jié)局限性的理解；要求學(xué)生結(jié)合生活實例探討其弊端有助于加強對其產(chǎn)生原因和表現(xiàn)的記憶和理解。

在學(xué)生明確了稅收的含義之后，我將分別對稅收的三個基本特征進行解析。在講解了之后，并分別用實例對其進行說明，加深學(xué)生對知識點的印象。最重要的是，總結(jié)出關(guān)鍵的字眼，使得學(xué)生能夠清晰的區(qū)分出稅收的三個基本特征。將強制性概括為依法征稅、依法納稅；無償性概括為不具有償還性和返還型；固定性概括為規(guī)定應(yīng)不應(yīng)納稅、納什么稅、納多少稅。并跟學(xué)生指出，強制性是基本前提，無償性是核心。由此根據(jù)書上的內(nèi)容，推導(dǎo)出稅收的三個基本特征相互之間的關(guān)系，即：三者缺一不可，統(tǒng)一于稅法。而且，無償性要求強制性，強制性保障無償性；而無償性與強制性又共同決定固定性。從而結(jié)束新課講授。3、課堂總結(jié)根據(jù)板書內(nèi)容重新回顧本課學(xué)習(xí)的主要內(nèi)容，包括稅收的含義，以及稅收的三個基本特征和它們之間的相互關(guān)系。4、作業(yè)布置讓學(xué)生預(yù)習(xí)稅收的種類的內(nèi)容，尤其是增值稅和個人所得稅。同時了解父母每月所繳納的個人所得稅和怎么計算的。

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(dá)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。

在接下來的細(xì)讀環(huán)節(jié)，我套用了高考對閱讀理解的考查方式設(shè)置了5個問題，分別為三個推理判斷題，一個細(xì)節(jié)題和一個主旨大意題。學(xué)生需要對文章的內(nèi)容進行分析、歸納、推理、猜測等高級思維活動才能做出正確的回答。【設(shè)計意圖】這一過程是對學(xué)生進行細(xì)讀的訓(xùn)練，培養(yǎng)學(xué)生獲取特定信息和挖掘文章深層次信息的能力。第三環(huán)節(jié):Intensive-reading (精讀) 15′第三個環(huán)節(jié)精讀，既是最重要的環(huán)節(jié)，也是突破本課重難點的關(guān)鍵。首先，讓學(xué)生思考劇本中人物看到百萬英鎊前后的態(tài)度發(fā)生了怎樣的變化。其次，讓學(xué)生仔細(xì)閱讀文章，找出可以表現(xiàn)人物態(tài)度變化的具體的語言和動作。最后，讓學(xué)生總結(jié)人物的態(tài)度發(fā)生變化的根本原因是什么，從而引出Money Talks, 供學(xué)生思考?！驹O(shè)計意圖】通過一系列的活動培養(yǎng)學(xué)生學(xué)習(xí)從人物的語言和動作探究人物的心理，使學(xué)生進一步體會戲劇語言的魅力，從而對文章背后所反映的社會問題進行思考，也為下一步的討論環(huán)節(jié)做好鋪墊。

教學(xué)過程：（一）導(dǎo)入：課前放《愛的奉獻(xiàn)》歌曲，同時不斷播放一些有關(guān)“愛”的主題的圖片，渲染一種情感氛圍。師說：同學(xué)們，誰能說說這組圖片的主題應(yīng)該是什么？生（七嘴八舌）：母愛，不對是親情……是友情、還有人與人互相幫助……那組軍人圖片是說保衛(wèi)國家，應(yīng)該是愛國……那徐本禹和感動中國呢？…………生答：是關(guān)于愛的方面師說：不錯，是關(guān)于愛的方面。那么同學(xué)們，今天就以“愛的奉獻(xiàn)”為話題，來寫一篇議論文如何？生答：老師，還是寫記敘文吧。生答：就是，要不議論文寫出來也象記敘文。師問：為什么？生答：老師，這個話題太有話說了，一舉例子就收不住了，怎么看怎么象記敘文。生答：就是，再用一點形容詞，就更象了。眾人樂。師說：那么同學(xué)們誰能告訴我，為什么會出現(xiàn)這種問題？一生小聲說：還不是我們笨，不會寫。師說：不是笨，也不是不會寫，你們想為什么記敘文就會寫，一到議論文就不會了，那是因為同學(xué)們沒有明白議論文中的記敘與記敘文中的記敘有什么不同，所以一寫起議論文中的記敘，還是按照記敘文的寫法寫作，這自然就不行了。那好，今天我們就從如何寫議論文中的記敘講起。
