1.用CAI課件模擬汽車的啟動(dòng)過程。師生共同討論:①如果作用在物體上的力為恒力,且物體以勻速運(yùn)動(dòng),則力對(duì)物體做功的功率保持不變。此情況下,任意一段時(shí)間內(nèi)的平均功率與任一瞬時(shí)的瞬時(shí)功率都是相同的。②很多動(dòng)力機(jī)器通常有一個(gè)額定功率,且通常使其在額定功率狀態(tài)工作(如汽車),根據(jù)P=FV可知:當(dāng)路面阻力較小時(shí),牽引力也小,速度大,即汽車可以跑得快些;當(dāng)路面阻力較大,或爬坡時(shí),需要比較大的牽引力,速度必須小。這就是爬坡時(shí)汽車換低速擋的道理。③如果動(dòng)力機(jī)器在實(shí)際功率小于額定功率的條件下工作,例如汽車剛剛起動(dòng)后的一段時(shí)間內(nèi),速度逐漸增大過程中,牽引力仍可增大,即F和v可以同時(shí)增大,但是這一情況應(yīng)以二者乘積等于額定功率為限度,即當(dāng)實(shí)際功率大于額定功率以后,這種情況不可能實(shí)現(xiàn)。

(五)平拋運(yùn)動(dòng)規(guī)律的應(yīng)用例1:一架老式飛機(jī)在高出海面45m的高處,以80m/s的速度水平飛行,為了使飛機(jī)上投下的炸彈落在停在海面上的敵船,應(yīng)該在與轟炸目標(biāo)的水平距離為多遠(yuǎn)的地方投彈?不計(jì)空氣阻力。分析:對(duì)于這道題我們可以從以下幾個(gè)方面來考慮:(1)從水平飛行的飛機(jī)上投下的炸彈,做什么運(yùn)動(dòng)?為什么?(2)炸彈的這種運(yùn)動(dòng)可分解為哪兩個(gè)什么樣的分運(yùn)動(dòng)?3)要想使炸彈投到指定的目標(biāo)處,你認(rèn)為炸彈落地前在水平方向通過的距離與投彈時(shí)飛機(jī)離目標(biāo)的水平距離之間有什么關(guān)系?拓展:1、式飛機(jī)在高出海面45m的高處,以80m/s的速度水平飛行,尾追一艘以15m/s逃逸的敵船,為了使飛機(jī)上投下的炸彈正好擊中敵船,應(yīng)該在與轟炸目標(biāo)的水平距離為多遠(yuǎn)的地方投彈?不計(jì)空氣阻力。2、在一次摩托車跨越壕溝的表演中,摩托車從壕溝的一側(cè)以速度v=40m/s沿水平方向向另一側(cè),壕溝兩側(cè)的高度及寬度如圖所示,摩托車可看做質(zhì)點(diǎn),不計(jì)空氣阻力。(1)判斷摩托車能否跨越壕溝?請(qǐng)計(jì)算說明(2)若能跨過,求落地速度?

3.進(jìn)一步體會(huì)力是產(chǎn)生加速度的原因,并通過牛頓第二定律來理解勻速圓周運(yùn)動(dòng)、變速圓周運(yùn)動(dòng)及一般曲線運(yùn)動(dòng)的各自特點(diǎn)。(三)、情感、態(tài)度與價(jià)值觀1.在實(shí)驗(yàn)中,培養(yǎng)學(xué)生動(dòng)手、探究的習(xí)慣。2.體會(huì)實(shí)驗(yàn)的意義,感受成功的快樂,激發(fā)學(xué)生探究問題的熱情、樂于學(xué)習(xí)的品質(zhì)。教學(xué)重點(diǎn)1.體會(huì)牛頓第二定律在向心力上的應(yīng)用。2.明確向心力的意義、作用、公式及其變形,并經(jīng)行計(jì)算。教學(xué)難點(diǎn)1.對(duì)向心力的理解及來源的尋找。2.運(yùn)用向心力、向心加速度的知識(shí)解決圓周運(yùn)動(dòng)問題。教學(xué)過程(一)、 引入新課:復(fù)習(xí)提問:勻速圓周運(yùn)動(dòng)的物體的加速度——向心加速度,它的方向和大小有何特點(diǎn)呢?學(xué)生回答后進(jìn)一步引導(dǎo):那做勻速圓周運(yùn)動(dòng)物體的受力有什么特點(diǎn)呢?是什么力使物體做圓周運(yùn)動(dòng)而不沿直線飛出?請(qǐng)同學(xué)們先閱讀教材

【教學(xué)意圖】要了解中國(guó)傳統(tǒng)文化,必須閱讀古詩(shī)文名著名篇。但在中國(guó)文化形成過程中影響最大的是什么?可以說是儒家學(xué)說,包括《論語》這部經(jīng)典?!墩撜Z》等書是讀書人求仕做官的必修課本,是知識(shí)分子的思想言行基礎(chǔ),而且影響到整個(gè)社會(huì)生活,內(nèi)容包括倫理道德、教育體制、民間習(xí)俗等方面的思想。因此,要了解中國(guó)傳統(tǒng)文化,有必要讀一讀《論語》。【教學(xué)設(shè)計(jì)】因《論語》的年代已久遠(yuǎn),對(duì)學(xué)生而言,要理解透徹文句是比較深?yuàn)W困難的,因此必須在充分理解文意的基礎(chǔ)上,對(duì)《論語》進(jìn)行思想上的解讀??捎山處煆摹墩撜Z》中概括出幾點(diǎn)與生活、現(xiàn)實(shí)相關(guān)的要點(diǎn),要求學(xué)生分組進(jìn)行透徹的學(xué)習(xí)和領(lǐng)會(huì),如“小人與君子”、“學(xué)習(xí)的方法”、“教育的理念”等等?!冀虒W(xué)重點(diǎn)、難點(diǎn)〗讀《論語》知儒家思想?!冀虒W(xué)方法〗講解啟發(fā)、探究梳理、拓展延伸。

全班齊讀第五段內(nèi)容。請(qǐng)一位同學(xué)分析,接著讓這位同學(xué)按他分析的讀一遍。3、4兩自然段的平緩之后,第5段作者的情感再次抬升。為了滿足這種情感的張揚(yáng),作一口氣連用了四個(gè)排比句式“現(xiàn)在是……時(shí)候”,一方面這是情感發(fā)泄的需要,另一方面這種排山倒海的語勢(shì)也加強(qiáng)了內(nèi)容的表達(dá),極強(qiáng)地突出了現(xiàn)實(shí)為自由、平等而戰(zhàn)的重要性。四、學(xué)會(huì)演講我們剛才細(xì)讀了課文,但讀和講是有區(qū)別的。所謂演講,是一門語言藝術(shù),它的主要形式是“講”,即運(yùn)用有聲語言并追求言辭的表現(xiàn)力和聲音的感染力;同時(shí)還要輔之以“演”,即運(yùn)用面部表情、手勢(shì)動(dòng)作、身體姿態(tài)乃至一切可以理解的態(tài)勢(shì)語言,使講話“藝術(shù)化”起來,從而產(chǎn)生一種非凡的藝術(shù)魅力。那么,接下來就假設(shè)一下假如你是馬丁·路德·金,你會(huì)怎樣去講這篇演講辭。

【教學(xué)目標(biāo)】1.熟讀全文,掌握文中出現(xiàn)的重要的實(shí)詞、虛詞、古漢語句式;2.鑒賞本文融情于事的表達(dá)和形象精粹的語言;3.深入體會(huì)文章凄切婉轉(zhuǎn)的陳情技巧。【教學(xué)重點(diǎn)】重要的古漢語語詞知識(shí)【教學(xué)難點(diǎn)】理解作者當(dāng)時(shí)的處境和李密祖孫間真摯深厚的感情【教學(xué)方法】作為教讀課,選擇串講的方式,突出朗讀,以期能做到既落實(shí)知識(shí),又能體會(huì)文章之美。課時(shí)安排為兩課時(shí)。要重點(diǎn)做好預(yù)習(xí)工作。【教學(xué)步驟】一、以蘇軾的評(píng)論導(dǎo)入讀《出師表》不下淚者,其人必不忠;讀《陳情表》不下淚者,其人必不孝;讀《祭十二郎文》不下淚者,其人必不友二、預(yù)習(xí)檢測(cè)1、下列紅色字注音完全正確的一項(xiàng)()A、臣以險(xiǎn)釁(xìn)夙遭閔(mǐn)兇終鮮(xiǎn)兄弟常在床蓐(rù)B、猥(wěi)以微賤責(zé)臣逋(bǔ)慢猶蒙衿(jīn)育寵命優(yōu)渥(wò)C、豈敢盤桓(huán)有所希冀(yì)日薄(bó)西山除臣洗(xiǎn)馬D、逮(dǎi)奉圣朝過蒙拔擢(zhuó)門衰祚(zuò)薄更(gēng)相為命分析:B責(zé)臣逋(bū)慢,C有所希冀(jì),D逮(dài)奉圣朝。

【教學(xué)過程】導(dǎo)入:如果說唐詩(shī)是中國(guó)文學(xué)史中的一朵奇葩,那孟浩然則是點(diǎn)綴其上的一滴晶瑩露珠,其充滿魅力與特色的詩(shī)風(fēng)在盛唐獨(dú)樹一幟,也為其在人才濟(jì)濟(jì)的詩(shī)史上刻下了永恒的印記。同學(xué)們能否先回憶一下,我們學(xué)過的孟浩然的詩(shī)歌有哪些?(《春曉》、《宿建德江》、《望洞庭湖贈(zèng)張丞相》、《過故人莊》。)我們常說"中國(guó)古詩(shī)寫胸襟,是人格美的自然流露",那么孟詩(shī)在語言和思想情感上留給你怎樣的印象和感受?整體感知:本文作者聞一多先生也是一位詩(shī)人,所謂"英雄惜英雄",相同的志向與情趣使聞一多似乎帶著我們?cè)谂c孟浩然進(jìn)行了一場(chǎng)心靈的對(duì)話。那么同學(xué)們?cè)诳焖匍喿x文章之后,能否先找出作者是選擇了一個(gè)怎樣的角度對(duì)孟浩然評(píng)價(jià)的?(詩(shī)如其人,人如其詩(shī)。)

【教學(xué)過程】第一課時(shí)一、導(dǎo)入新課清代唐彪在《讀書作文譜》中引用武叔卿的話說:“文章有一筆寫成不加點(diǎn)綴而工者,此神到之文,尚矣。其次須精思細(xì)改,如文章草創(chuàng)已定,便從頭至尾—一標(biāo)點(diǎn)?!蓖瑢W(xué)們能列舉出文學(xué)史上的作家哪些屬于前者,哪些屬于后者嗎?前者有李白。后者如賈島、王安石、歐陽修、曹雪芹等。(賈島有關(guān)于推敲的典故。王安石修改“春風(fēng)又綠江南岸”句傳為佳話。歐陽修《醉翁亭記》的開頭便是精心改成的?!都t樓夢(mèng)》更是“披閱十載,增刪五次?!保┨釂枺汗沤竦膫ゴ笞骷覟槭裁聪窭畎资降脑?shī)人很少,而大多數(shù)人卻都要“咬文嚼字”,苦苦修改呢?這節(jié)課我們就來研究一下這個(gè)問題。二、整體感知1.快速瀏覽全文,熟悉主要內(nèi)容。2.根據(jù)“學(xué)習(xí)重點(diǎn)”,確立學(xué)習(xí)目標(biāo)。三、課文分析1.理清觀點(diǎn)與材料的關(guān)系。首先,讓學(xué)生找出本文在論證中所運(yùn)用的材料。

一、作者簡(jiǎn)介:威廉·莎士比亞(1564~1616),英國(guó)文藝復(fù)興時(shí)期偉大的戲劇家和詩(shī)人。(人文主義:歐洲文藝復(fù)興時(shí)期新興資產(chǎn)階級(jí)反封建的社會(huì)思潮。資產(chǎn)階級(jí)人道主義的最初形式。它肯定人性和人的價(jià)值,要求享受人世的歡樂,要求人的個(gè)性解放和自由平等,推崇人的感性經(jīng)驗(yàn)和理性思維。)一生共寫有37部戲劇,154首14行詩(shī),兩首長(zhǎng)詩(shī)和許多其他詩(shī)歌。主要代表作有早期的歷史劇、喜劇———《亨利四世》、《仲夏夜之夢(mèng)》、《威尼斯商人》和《羅密歐與朱麗葉》等;中期的悲劇———《哈姆萊特》、《奧瑟羅》、《李爾王》和《麥克白》等;后期的傳奇劇———《暴風(fēng)雨》等。二、莎士比亞創(chuàng)作《哈姆萊特》的社會(huì)背景:莎士比亞是歐洲文藝復(fù)興時(shí)期英國(guó)偉大的戲劇家和詩(shī)人。他生活在歐洲歷史上封建制度日趨沒落、資本主義興起的交替時(shí)代。哈姆萊特是丹麥古代的王子。莎士比亞故意以超越時(shí)代的誤差將哈姆萊特搬到伊麗莎白統(tǒng)治未年的英國(guó)現(xiàn)實(shí)中來。

教師總結(jié):近二十多年來,我國(guó)個(gè)人所得稅的征收發(fā)展迅速,這也反映了我國(guó)經(jīng)濟(jì)水平、人民生活收入有了較大提高。與增值稅的計(jì)稅方法不同,個(gè)人所得稅采用累進(jìn)稅率的計(jì)稅辦法,就是個(gè)人所得越高,稅率越高,納稅人個(gè)人收入越多,繳納個(gè)人所得稅越多。這一特點(diǎn)從教材83頁個(gè)人所得稅稅率表上可以看出。教師點(diǎn)撥:個(gè)人所得稅的計(jì)算辦法是分段計(jì)算的,個(gè)人收入800元以內(nèi)不計(jì)稅,多余800元以上部分,按不同稅率分段計(jì)稅。請(qǐng)同學(xué)們計(jì)算教材所列題目。學(xué)生活動(dòng):計(jì)算。應(yīng)稅所得額:4000元;不超過500元部分:25元;500――2000元部分:150元;2000――4000元部分:300元;累計(jì)所得稅:475元教師活動(dòng):同學(xué)們想一想,這樣計(jì)算個(gè)人所得稅有什么意義呢?學(xué)生活動(dòng):認(rèn)真思考,回答問題教師點(diǎn)撥:有利于增加財(cái)政收入,有利于調(diào)節(jié)個(gè)人收入分配,實(shí)現(xiàn)社會(huì)公平。(三)課堂總結(jié)、點(diǎn)評(píng)

This teaching period mainly deals with grammar “restrictive relative clauses.” To begin with, teachers should lead students to revise what they have learned about the relative pronouns and relative adverbs. And then, teachers move on to stress more special cases concerning this grammar, such as the “preposition+ relative pronouns which and whom” and cases where we can omit the relative pronouns. This period carries considerable significance to the cultivation of students’ writing competence and lays a solid foundation for the basic appreciation of language beauty. The teacher is expected to enable students to master this period thoroughly and consolidate the knowledge by doing some exercises. 1. Guide students to review the basic usages of relative pronouns and adverbs of attributive clauses.2. Lead students to learn to use some special cases concerning restrictive relative clauses flexibly.2. Enable students to use the basic phrases structures flexibly.3. Strengthen students’ great interest in grammar learning.1. Help students to appreciate the function of relative pronouns and adverbs of attributive clauses in a sentence2.

The theme of this unit is human and nature, focusing on the theme of wildlife protection. Nature is a complex ecosystem, in which there are delicate balance between animals and plants. Because of the role of the food chain, the extinction of one species will produce influence, causing a series of chain reaction. Large scale extinction of species will have a serious and even irreversible impact on the ecosystem, resulting in immeasurable losses. Therefore, it is of great significance to protect wild species. To protect wild species is to protect human beings themselves. The motto of this unit is "when the buying stops, the killing can too,” which is a public service advertising slogan to protect wildlife. It tells people that every rhinoceros horn, every fur, every bowl of shark fin soup, every Ivory product, and every tiger bone product, etc. consumed by human beings, are innocent wild animals slaughtered behind them. The mission of wild aid is to ban illegal trade in endangered wildlife and mitigate climate change. It aims to educate the public to reduce the consumption demand for endangered wildlife products through public publicity and improve the awareness of environmental protection.1. Improve the awareness of wildlife protection by acquiring the knowledge of wildlife protection.2. Focus on environmental protection and protection of all lives.3. Analysis of the living environment of wild animals with appropriate thinking mode.4. Skillfully use the vocabulary and grammar knowledge of this unit to cultivate self-study ability according to the unit content5. Develop cooperative learning ability through discussion and other ways1. Enable the Ss to talk about the current situation of wild animals.2. Guide the Ss to summarize the main idea of each paragraph as well as the main idea of the text.
