人教版高中政治必修2民主監(jiān)督：守望公共家園教案
一、教材分析《民主監(jiān)督：守望公共家園》是高一政治必修2第一單元第二課第四框題。在此之前，學(xué)生們已經(jīng)學(xué)習(xí)了公民所享有的政治權(quán)利和自由，了解到公民享有監(jiān)督權(quán)，這為過(guò)渡到本框題的學(xué)習(xí)起到了鋪墊的作用。本框題承接了教材第一課“公民的政治權(quán)利和自由”這部分內(nèi)容，又為后面第四課“權(quán)力的行使：需要監(jiān)督”的學(xué)習(xí)埋下伏筆。所以學(xué)好這個(gè)框題為學(xué)好以后的政治常識(shí)打下牢固的基礎(chǔ)，而且它在整個(gè)教材中也起到了承上啟下的作用。二、教學(xué)目標(biāo)（一）知識(shí)目標(biāo)1、識(shí)記公民的民主監(jiān)督權(quán)利、作用2、理解公民的民主監(jiān)督的重要性。3、學(xué)會(huì)分析如何行使監(jiān)督權(quán)（二）能力目標(biāo)通過(guò)學(xué)習(xí)逐步形成民主監(jiān)督能力。（三）情感、態(tài)度與價(jià)值觀目標(biāo)通過(guò)學(xué)習(xí)培養(yǎng)學(xué)生主人翁責(zé)任感。三、教學(xué)重點(diǎn)難點(diǎn)重點(diǎn)：公民的民主監(jiān)督權(quán)利、作用、重要性。難點(diǎn)：民主監(jiān)督的重要性

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.

1. 這個(gè)寓言是一個(gè)關(guān)于一位國(guó)王古寓言。 The fable is an old fable about a king.2.作者用這個(gè)故事讓讀者對(duì)于社區(qū)的問(wèn)題負(fù)有個(gè)人責(zé)任的必要印象深刻。The author used the story to impress upon readers with the need to take personal responsibility for problems in the community.3. 這個(gè)故事十分成功的實(shí)現(xiàn)了它的目的。The story was quite successful in achieving its purpose.Step 7 WritingPlease write a review of the story according the outline above.The fable is an old fable about a king who thought his people are lazy, so he put a large stone in the middle of the road and hides and waited to see if anyone will try to move it.The author used this story to impress upon readers with the need to take personal responsibility for problems in the community. The story was quite successful in achieving its purpose, and I liked it because it had a clear moral.However, while the moral of the story is clear, the actions of the king seemed pointless to me, because none of the characters in the story learnt anything. For this reason, I think there are better stories that can be used to impress upon people with the need for personal responsibility.Step 8 Pair workExchange drafts with a partner. Use this checklist to help your partner revise his/her draft.1. Does the writer give a short description of the story ?2. Does the description include the most important details of the story ?3.

3．作者為什么不直接描寫人們看見(jiàn)東西呢？請(qǐng)同學(xué)們找出其中的細(xì)節(jié)描寫，并說(shuō)明有什么表達(dá)效果。答：側(cè)面烘托，正是作者高明之處，這也是許多佳作常用之法。細(xì)節(jié)描寫往往會(huì)成為事情的切入點(diǎn)和突破口，一篇佳作往往離不開(kāi)一些細(xì)節(jié)描寫，本文也不例外，有些細(xì)節(jié)描寫耐人尋味，如：“德國(guó)人撤退時(shí)炸毀的布熱金卡毒氣室和焚尸爐廢墟上，雛菊花在怒放。”“這是一個(gè)二十多歲的姑娘，長(zhǎng)得豐滿，可愛(ài)，皮膚細(xì)白，金發(fā)碧眼。她在溫和地微笑著，似乎是為著一個(gè)美好而又隱秘的夢(mèng)想而微笑?！?.句子賞析：“對(duì)另外一些人來(lái)說(shuō)，這樣一個(gè)事實(shí)使他們終生難忘：在德國(guó)人撤退時(shí)炸毀的布熱金卡毒氣室和焚尸爐廢墟上，雛菊花在怒放?！泵鞔_：一邊是戕害生命的毒氣室和焚尸爐，一邊是生機(jī)勃勃的生命，兩種反差極大的事物擺在一起。表達(dá)了作者對(duì)納粹的諷刺：納粹的殘暴終歸阻止不了生命的進(jìn)程。同時(shí)也表達(dá)了作者的控訴：生命的綻放是人世間最美好的事情，對(duì)生命的戕害是最惡劣的罪行。
人教版高中語(yǔ)文必修3《善待生命 學(xué)習(xí)論證》教案2篇
論證方法之引證法如何用好引證法：1.所引用的名言警句等針對(duì)性要強(qiáng)。每句名言都產(chǎn)生于特定的背景，都應(yīng)用于特定的交際目的，即使談同一個(gè)問(wèn)題，也有不少名言可供選取。2.要簡(jiǎn)潔，不宜過(guò)多。議論是在發(fā)表自己的見(jiàn)解而不是在介紹他人的見(jiàn)解。引用他人的話，目的是為了讓讀者更加信服自己的話。3.要注意直接引用和間接引用的區(qū)別。直接引用務(wù)求文字、甚至標(biāo)點(diǎn)均準(zhǔn)確無(wú)誤；間接引用只須述其大意，但要注意人稱的轉(zhuǎn)換。論證方法之喻證法喻證法是用設(shè)喻來(lái)論證論點(diǎn)的方法。在議論文中，設(shè)喻可以使論點(diǎn)更易懂、更風(fēng)趣、更容易獲得讀者的認(rèn)同。喻證法能化抽象為具體、化艱深為淺顯、化枯燥為生動(dòng)。論證方法之喻證法如何用好喻證法：1.以小見(jiàn)大，就近取譬。要精選生活中細(xì)小的、人們熟悉的事物做為設(shè)喻的喻體。2.喻體不求形似，只求神似。做為喻證的喻體與做為比喻的喻體不同。比喻的喻體是為了強(qiáng)調(diào)特征，描繪事物，側(cè)重形似，以形比形；而喻證的喻體是為了闡發(fā)觀點(diǎn)，以正視聽(tīng)，力求神似，以義取形。

評(píng)價(jià)分析法，就是引述事例后，對(duì)所引述的事例作適當(dāng)?shù)脑u(píng)價(jià)，從而使自己的觀點(diǎn)得到印證。例如，在論“節(jié)儉”時(shí)，引用了“曾國(guó)藩以儉戒子，其子曾紀(jì)澤終成出色的外交家；方志敏居官不貪，一生清貧，千古留名”的事實(shí)后，接著進(jìn)行分析：是的，“儉者心常富”，節(jié)儉能培養(yǎng)人同困難作斗爭(zhēng)的勇氣和意志，而這正是一個(gè)人立業(yè)最重要的素質(zhì)。從這個(gè)意義上說(shuō)，有人說(shuō)饑餓是人生的佐料，吃苦是一種資本也不無(wú)道理，而自覺(jué)和戒奢尚儉則更是促人修身養(yǎng)性，磨煉意志的有效途徑。這里，作者緊扣論點(diǎn)，對(duì)論據(jù)進(jìn)行了評(píng)價(jià)性分析，這種評(píng)價(jià)分析使作者的觀點(diǎn)得到強(qiáng)化。（四）因果分析法因果分析法，就是抓住論據(jù)所述的事實(shí)，并據(jù)此推求形成原因的一種分析方法。事出必有其因。我們可以依據(jù)事物發(fā)展變化的因果關(guān)系，由事物發(fā)展變化的結(jié)果，推導(dǎo)出產(chǎn)生這種結(jié)果的原因，從而揭示出一定的生活規(guī)律，使事例有力地證明觀點(diǎn)。
人教版高中歷史必修3“罷黜百家獨(dú)尊儒術(shù)”教案2篇
戰(zhàn)國(guó)陰陽(yáng)五行家鄒衍認(rèn)為，歷史中的朝代更替是由于五德運(yùn)行產(chǎn)生的影響。按照鄒衍的學(xué)說(shuō)，每個(gè)朝代必須與五德之一相連，因此，這個(gè)朝代就應(yīng)當(dāng)遵循這五德之一的要求來(lái)運(yùn)轉(zhuǎn)。董仲舒修改了這個(gè)理論，認(rèn)為朝代的更替不是依循五德運(yùn)行的順序，而是依循“三統(tǒng)”，即黑統(tǒng)、白統(tǒng)、赤統(tǒng)的順序。他在《三代改制質(zhì)文》中說(shuō)：每個(gè)朝代都依循一統(tǒng)，每統(tǒng)又各有其為政的系統(tǒng)。按董仲舒的說(shuō)法，夏朝代表黑統(tǒng)，商朝代表白統(tǒng)；周朝則是赤統(tǒng)。夏、商、周三朝完成了這一歷史循環(huán)。之后，歷史又開(kāi)始一次新的循環(huán)，新的朝代又應(yīng)當(dāng)代表黑統(tǒng)。繼承周朝統(tǒng)治的既不是秦朝，也不是漢朝，而是孔子，他承受天命，創(chuàng)立了黑統(tǒng)?？鬃铀芴烀?，不是一種“法統(tǒng)”，而是一種“道統(tǒng)”。董仲舒說(shuō)：“《春秋》大一統(tǒng)者，天地之常經(jīng)，古今之通誼也。今師異道，人異論，百家殊方，指意不同，是以上亡以持一統(tǒng)；法制數(shù)變，下不知所守。臣愚以為諸不在六藝之科孔子之術(shù)者，皆絕其道，勿使并進(jìn)。邪辟之說(shuō)滅息，然后統(tǒng)紀(jì)可一而法度可明，民知所從矣。”

三個(gè)“二次”即一元二次函數(shù)、一元二次方程、一元二次不等式是高中數(shù)學(xué)的重要內(nèi)容，具有豐富的內(nèi)涵和密切的聯(lián)系，同時(shí)也是研究包含二次曲線在內(nèi)的許多內(nèi)容的工具 高考試題中近一半的試題與這三個(gè)“二次”問(wèn)題有關(guān) 本節(jié)主要是幫助考生理解三者之間的區(qū)別及聯(lián)系，掌握函數(shù)、方程及不等式的思想和方法。課程目標(biāo)1. 通過(guò)探索，使學(xué)生理解二次函數(shù)與一元二次方程，一元二次不等式之間的聯(lián)系。2. 使學(xué)生能夠運(yùn)用二次函數(shù)及其圖像，性質(zhì)解決實(shí)際問(wèn)題． 3. 滲透數(shù)形結(jié)合思想，進(jìn)一步培養(yǎng)學(xué)生綜合解題能力。數(shù)學(xué)學(xué)科素養(yǎng)1.數(shù)學(xué)抽象：一元二次函數(shù)與一元二次方程，一元二次不等式之間的聯(lián)系；2.邏輯推理：一元二次不等式恒成立問(wèn)題；3.數(shù)學(xué)運(yùn)算：解一元二次不等式；4.數(shù)據(jù)分析：一元二次不等式解決實(shí)際問(wèn)題；5.數(shù)學(xué)建模：運(yùn)用數(shù)形結(jié)合的思想，逐步滲透一元二次函數(shù)與一元二次方程，一元二次不等式之間的聯(lián)系。
《說(shuō)“木葉”》說(shuō)課稿（一） 2021-2022學(xué)年統(tǒng)編版高中語(yǔ)文必修下冊(cè)
這五個(gè)問(wèn)題，主要從學(xué)情出發(fā)，由淺入深，從感知到理論，培養(yǎng)學(xué)生的鑒賞能力。第三環(huán)節(jié)：延伸探究、展示成果(多媒體顯示）走出文本，引入課外同類文學(xué)現(xiàn)象，讓學(xué)生能夠觸類旁通，舉一反三，把教材作為一個(gè)例子，讓學(xué)生在深入的文學(xué)鑒賞中再次獲得語(yǔ)言的審美。同學(xué)們初步掌握了文學(xué)語(yǔ)言具有暗示性的性質(zhì)后，還需鞏固、提升鑒賞能力!這里我采取的方法是：引導(dǎo)學(xué)生認(rèn)真閱讀文本，經(jīng)小組合作探究后，得出本組的鑒賞成果并加以展示，這里重在培養(yǎng)學(xué)生的理解能力和分析綜合能力。問(wèn)題是：1、 請(qǐng)結(jié)合下面三首詞的意境，選用殘紅、落紅、亂紅填空。2、 閱讀下面這些句子，理解“燕”在詞語(yǔ)中的暗示意義。該環(huán)節(jié)充分體現(xiàn)了 “ 教師為主導(dǎo)，學(xué)生為主體”的原則。老師的適時(shí)點(diǎn)撥，讓學(xué)生的鑒賞思路更加清晰。學(xué)生通過(guò)合作探究，理解能力和分析綜合能力得到了提升。
