讀《環(huán)境污染組圖》思考:造成交通擁擠的原因是什么?有什么危害?(原因:汽車的增加、汽車數(shù)量與道路狀況的比值越來越大造成的。危害:交通阻塞,導(dǎo)致時間和能源的嚴重浪費,影響城市環(huán)境質(zhì)量。)3.增加就業(yè)困難,失業(yè)人數(shù)增多思考:產(chǎn)生這個問題的原因是什么?(隨著城市化發(fā)展,城市科學(xué)技術(shù)提高,機器化大生產(chǎn)使勞動者數(shù)量要求降低,城市人口本來就未充分就業(yè),再加上鄉(xiāng)村人口大量涌入,導(dǎo)致失業(yè)人數(shù)增多。)二、解決辦法:(以上海市為例,講解解決的辦法。)1.改善城市環(huán)境:治理河流、控制大氣污染物、大力加強綠化建設(shè)為改善城市環(huán)境,上海市全面展開對大氣、河流、噪聲等多方面的治理工作。如蘇州河的治理、降低城市污染物濃度、加強綠化建設(shè),截止1990年,市區(qū)綠化覆蓋率達到20.3%。
1.用CAI課件模擬汽車的啟動過程。師生共同討論:①如果作用在物體上的力為恒力,且物體以勻速運動,則力對物體做功的功率保持不變。此情況下,任意一段時間內(nèi)的平均功率與任一瞬時的瞬時功率都是相同的。②很多動力機器通常有一個額定功率,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,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,需要比較大的牽引力,速度必須小。這就是爬坡時汽車換低速擋的道理。③如果動力機器在實際功率小于額定功率的條件下工作,例如汽車剛剛起動后的一段時間內(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)實際功率大于額定功率以后,這種情況不可能實現(xiàn)。
3.進一步體會力是產(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動、變速圓周運動及一般曲線運動的各自特點。(三)、情感、態(tài)度與價值觀1.在實驗中,培養(yǎng)學(xué)生動手、探究的習(xí)慣。2.體會實驗的意義,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1.體會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)行計算。教學(xué)難點1.對向心力的理解及來源的尋找。2.運用向心力、向心加速度的知識解決圓周運動問題。教學(xué)過程(一)、 引入新課:復(fù)習(xí)提問:勻速圓周運動的物體的加速度——向心加速度,它的方向和大小有何特點呢?學(xué)生回答后進一步引導(dǎo):那做勻速圓周運動物體的受力有什么特點呢?是什么力使物體做圓周運動而不沿直線飛出?請同學(xué)們先閱讀教材
一、教材內(nèi)容經(jīng)全國中小學(xué)教材審定委員會2004年初審查通過,人教育出版社出版的普通高中課程標準實驗教科書《物理必修①》,第三章第5節(jié)內(nèi)容“力的分解”。二、教學(xué)目標1.知識與技能(1)理解分力的概念,理解力的分解是力的合成的逆運算,遵循平行四邊形定則。(2)初步掌握一般情況下力的分解要根據(jù)實際需要來確定分力的方向。(3)會用作圖法和直角三角形的知識求分力。(4)能區(qū)別矢量和標量,知道三角形定則,了解三角形定則與平行四邊形定則的實質(zhì)是一樣的。2.過程與方法(1)進一步領(lǐng)會“等效替代”的思想方法。(2)通過探究嘗試發(fā)現(xiàn)問題、探索問題、解決問題能力。(3)掌握應(yīng)用數(shù)學(xué)知識解決物理問題的能力。3.情感態(tài)度與價值觀(1)通過猜測與探究享受成功的快樂。(2)感受物理就在身邊,有將物理知識應(yīng)用于生活和生產(chǎn)實驗的意識。三、教學(xué)重點、難點在具體問題中如何根據(jù)力的實際作用效果和平行四邊形定則進行力的分解。
l.知識與技能:(1)知道摩擦力產(chǎn)生的條件。(2)能在簡單問題中,根據(jù)物體的運動狀態(tài),判斷靜摩擦力的有無、大小和方向;知道存在著最大靜摩擦力。(3)掌握動磨擦因數(shù),會在具體問題中計算滑動磨擦力,掌握判定摩擦力方向的方法。(4)知道影響到摩擦因數(shù)的因素。2.過程與方法:通過觀察演示實驗,概括出摩擦力產(chǎn)生的條件及摩擦力的特點,培養(yǎng)學(xué)生的觀察、概括能力。通過靜摩擦力與滑動摩擦力的區(qū)別對比,培養(yǎng)學(xué)生分析綜合能力。3.情感態(tài)度價值觀:在分析物體所受摩擦力時,突出主要矛盾,忽略次要因素及無關(guān)因素,總結(jié)出摩擦力產(chǎn)生的條件和規(guī)律。二、重點、難點分析1.本節(jié)課的內(nèi)容分滑動摩擦力和靜摩擦力兩部分。重點是摩擦力產(chǎn)生的條件、特性和規(guī)律,通過演示實驗得出關(guān)系f=μN。2.難點是學(xué)生有初中的知識,往往誤認為壓力N的大小總是跟滑動物體所受的重力相等,因此必須指出只有當(dāng)兩物體的接觸面垂直,物體在水平拉力作用下,沿水平面滑動時,壓力N的大小才跟物體所受的重力相等。
一般情況下,凡是支持物對物體的支持力,都是支持物因發(fā)生形變而對物體產(chǎn)生彈力。所以支持力的方向總是垂直于支持面而指向被支持的物體。例1:放在水平桌面上的書書由于重力的作用而壓迫桌面,使書和桌面同時發(fā)生微小形變,要恢復(fù)原狀,對桌面產(chǎn)生垂直于桌面向下的彈力f1,這就是書對桌面的壓力;桌面由于發(fā)生微小的形變,對書產(chǎn)生垂直于書面向上的彈力f2,這就是桌面對書的支持力。學(xué)生分析:靜止地放在傾斜木板上的書,書對木板的壓力和木板對書的支持力。并畫出力的示意圖。結(jié)論:壓力、支持力都是彈力。壓力的方向總是垂直于支持面而指向被壓的物體,支持力的方向總是垂直于支持面而指向被支持的物體。引導(dǎo)學(xué)生分析靜止時,懸繩對重物的拉力及方向。引導(dǎo)得出:懸掛物由于重力的作用而拉緊懸繩,使重物、懸繩同時發(fā)生微小的形變。重物由于發(fā)生微小的形變,對懸繩產(chǎn)生豎直向下的彈力f1,這是物對繩的拉力;懸繩由于發(fā)生微小形變,對物產(chǎn)生豎直向上的彈力f2,這就是繩對物體的拉力。
蘇聯(lián)文學(xué)的沿革,既反映了蘇聯(lián)社會的偉大思想性變革,又反映了蘇聯(lián)文壇活躍與混亂并存的局面,特別是其所具有強烈的意識形態(tài)色彩是蘇聯(lián)社會深層次變化的風(fēng)向標。(2)20世紀的亞、非、拉美文學(xué)20世紀亞、非、拉美文學(xué)的繁榮伴隨著民族民主運動的高漲,其主流都體現(xiàn)了反對殖民壓迫、反對社會不公的愛國主義精神。出現(xiàn)了許多頗有影響的作家和作品。泰戈爾是印度近現(xiàn)代文學(xué)的光輝代表,為印度現(xiàn)代民族主義奠定了基礎(chǔ)。其代表作《戈拉》塑造了愛國的印度民族主義知識分子形象。泰戈爾是首位獲諾貝爾文學(xué)獎的東方作家。魯迅是中國文學(xué)革命的巨匠,他的《吶喊》集,昭示著中國新文學(xué)時代的到來。哥倫比亞作家馬爾克斯的《百年孤獨》,描繪加勒比海沿岸小城百年孤獨的原因及打破這種狀態(tài)的途徑。
畫中的諸多圖像反映了畫家對于傳統(tǒng)繪畫因素的吸收。那個懷抱死去孩子的母親圖像,似乎是源自哀悼基督的圣母像傳統(tǒng);手持油燈的女人,使人聯(lián)想起自由女神像的造型;那個高舉雙手仰天驚呼的形象,與戈雅畫中愛國者就義的身姿不無相似之處;而那個張臂倒地的士兵形象,則似乎與意大利文藝復(fù)興早期某些戰(zhàn)爭畫中的形象,有著姻親關(guān)系。由此可以看出,畢加索不僅是一位富于叛逆精神的大膽創(chuàng)新者,同時也是一位尊崇和精通傳統(tǒng)的藝術(shù)家。教師須強調(diào):現(xiàn)代主義美術(shù)是現(xiàn)代美術(shù)流派的總稱,現(xiàn)代美術(shù)流派眾多,多姿多彩,但它們也表現(xiàn)出許多共同的特征。在技法上,它們大都反對傳統(tǒng)的寫實主義,追求新奇,空間結(jié)構(gòu)錯亂,色彩配置隨意,點線紊亂,缺乏透視可謂它們共有的特點。在創(chuàng)作主旨上,它們都主張強調(diào)自我,表現(xiàn)個人情感和內(nèi)心世界??梢哉f,現(xiàn)代美術(shù)藝術(shù)再現(xiàn)了20世紀西方世界的精神狀況。
二、程朱理學(xué):1、宋代“理學(xué)”的產(chǎn)生:(1)含義:所謂“理學(xué)”,就是用“理學(xué)”一詞來指明當(dāng)時兩宋時期所呈現(xiàn)出來的儒學(xué)。廣義的理學(xué),泛指以討論天道問題為中心的整個哲學(xué)思潮,包括各種不同的學(xué)派;狹義的理學(xué),專指程顥、程頤、朱熹為代表的,以“理”為最高范疇的學(xué)說,稱為“程朱理學(xué)”。理學(xué)是北宋政治、社會、經(jīng)濟發(fā)展的理論表現(xiàn),是中國古代哲學(xué)長期發(fā)展的結(jié)果,是批判佛、道學(xué)說的產(chǎn)物。他們把“理”或“天理”視作哲學(xué)的最高范疇,認為理無所不在,不生不滅,不僅是世界的本原,也是社會生活的最高準則。在窮理方法上,程顥“主靜”,強調(diào)“正心誠意”;程頤“主敬”,強調(diào)“格物致知”。在人性論上,二程主張“去人欲,存天理”,并深入闡釋這一觀點使之更加系統(tǒng)化。二程學(xué)說的出現(xiàn),標志著宋代“理學(xué)”思想體系的正式形成。【合作探究】宋代“理學(xué)”興起的社會條件:

8. However, the more polite you are, the less likely it is you will be attacked. 然而, 你越有禮貌, 你被攻擊的可能性就越小。 Step 8 Writing---the articleHow to stay safe in the online chat roomToday I thought I’d blog about a question that has been asked many times--- how do you stay safe online and avoid bad experiences in the online chat room ? I’m not an expert, but many years as a blogger have taught me a thing or two.First of all, there’s the golden rule of the Internet: keep out of what makes you uneasy. Don’t post comments or click on anything. Second, protect your privacy. Don’t give out too much private information like your address, phone numbers, the ID numbers, etc. Third, be polite. If you are polite to others on the Internet, you won’t be attacked in normal situation. Finally, don’t believe in others easily and never meet someone you met online alone. It is very dangerous.Have you had any bad experiences online, or do you have some good advice for staying safe? Post your comments below!Step 9 Pair workExchange drafts with a partner.

This unit is about the Internet, which has a great influence to our humans and our lives. During the Listening & Speaking & Talking and Reading and Thinking section, the influence in examples has been shown. Thus, use the Present Perfect Tense is appropriate. However, in order to show the justice or weaken the doer of the behavior/action, it’s better to use the Present Perfect Passive Voice than the Present Perfect Tense. Besides, having learned to use the Present Perfect Passive Voice, students can beautify their language in their writing. 1. Learn the structure of the Present Perfect Passive Voice and its functions. 2. Learn to change the sentences with the Present Perfect Passive Voice into the sentences with the Present Perfect Passive Voice. 3.
