This teaching period mainly deals with grammar “The Present Perfect Passive Voice.” To begin with, teachers should lead students to revise what they have learned about the Present Perfect Passive Voice. And then, teachers move on to stress more special cases concerning this grammar。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 the Present Perfect Passive Voice2. Lead students to learn to use some special cases concerning the Present Perfect Passive Voice 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 the Present Perfect Passive Voice in a sentence2. Instruct students to write essays using the proper the Present Perfect Passive Voice.觀察下列句子特點,總結(jié)共同點。1.(教材P28)Much has been written about the wonders of the World Wide Web.2.(教材P28)But the Internet has done much more for people than simply make life more convenient.3.(教材P28)Many people have been helped by the club.4.(教材P28)She no longer feels lonely, and her company has become quite successful.5.(教材P32)Today I thought I’d blog about a question that has been asked many times—how do you stay safe online and avoid bad experiences on the Internet?
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. Learn to write sentences with the Present Perfect Passive Voice flexibly according to the context. 1. Learn the structure of the Present Perfect Passive Voice and its functions. 2.

一、內(nèi)容與解析內(nèi)容:科普說明文《動物游戲之謎》。解析:《動物游戲之謎》是高中語文(必修)3第四單元的一篇科普說明文??茖W(xué)是人類認(rèn)識世界的重要工具,是人類文化的重要組成部分,是標(biāo)志人類文明的尺度。閱讀科普文章,可以啟迪心志,激發(fā)想象,帶領(lǐng)我們進(jìn)入全新的科學(xué)天地,在科學(xué)海洋中遨游。本文思路清晰,內(nèi)容生動,揭開了動物日常游戲行為的神秘面紗,擺出研究者的種種結(jié)論,既讓我們擴(kuò)大了視野,增長了知識,也讓我們明白了科學(xué)探索永無止境。學(xué)習(xí)本文的重點是提高的科普文的閱讀能力,培養(yǎng)學(xué)生勤于探索、勇于鉆研的科學(xué)精神。二、教學(xué)目標(biāo)及解析1、理清文章思路,明確本文的說明內(nèi)容和順序。2、品讀文章,感受本文的語言特色。3、激發(fā)探究興趣,培養(yǎng)篩選信息、提取要素及概括敘述的能力。4、挖掘人文內(nèi)涵,培養(yǎng)學(xué)生保護(hù)動物的意識和勤于探索、勇于鉆研的科學(xué)精神。
結(jié)合歷史自古以來,江山美人歷來都是引無數(shù)英雄豪杰競折腰的,如果說英雄選擇了美人卻丟了江山,把所有罪名都?xì)w結(jié)于“女人是禍水”。但是,紂王無道,和有了妲己有必然的聯(lián)系嗎?有人說妲己壞透了,壞透了的妲己如果不是取得紂王的信任是壞不起來的,紂王聽信了妲己的讒言,聽與不聽決定權(quán)在紂王,而不在妲己。強勢永遠(yuǎn)在紂王一邊。再來看看西施和楊貴妃:西施是作為越國貢獻(xiàn)給吳國的供品來到吳王夫差的身邊的,楊貴妃更是先是李隆基的兒媳婦被看中而得寵的。所以,西施和楊貴妃這兩個可憐的女人根本沒有自己的獨立選擇,沒有獨立的愛情,如果沒有西施,就會有南施,或北施;如果沒有楊貴妃,就會有李貴妃,王貴妃,總之什么施,什么妃是不能少的,因為那是吳王和李隆基的需要。
一、知識與能力:(1)了解中國古代不同時期的文學(xué)特色;(2)了解、詩,詞、歌、賦等各種不同的知識內(nèi)容和形式,知道和掌握一定數(shù)量的名家作品;(3)拓寬文化視野,提高賞析和運用古代文學(xué)作品的能力。二、過程與方法:(1)通過教科書及教師提供的材料以及自己的日常積累,通過閱讀,討論,分析,評論了解各個不同時期的文學(xué)發(fā)展特色。(2)通過閱讀,觀察,練習(xí),欣賞,表演,評論,創(chuàng)作等方式積極參與教學(xué);通過獨立思考或合作學(xué)習(xí)對所學(xué)的內(nèi)容進(jìn)行比較,概括和闡釋;學(xué)會合作學(xué)習(xí)和相互交流。三、情感態(tài)度與價值觀:通過本課學(xué)習(xí),了解中國古代燦爛的文化。通過對文學(xué)家、詩人及其文學(xué)作品的分析,把學(xué)生帶進(jìn)文學(xué)藝術(shù)的殿堂,感受古人的呼吸,思想,情操。增強文化修養(yǎng)。
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(jì)西方世界的精神狀況。
三、第三階段。課后感悟與收獲1、讓學(xué)生以“走向?qū)W習(xí)型社會”為題,將在收集與整理、展示與交流兩個環(huán)節(jié)中獲得的體驗和感悟,以心得體會的形式寫一篇小論文。2、辦一期專欄或黑板報,將優(yōu)秀小論文作集中展示與交流。(進(jìn)行理論總結(jié),將實踐與理論相結(jié)合,讓科學(xué)理論更好地指導(dǎo)實踐。充分挖掘?qū)W生潛力,增強學(xué)生的自信)[評析]新課程理念之一就是政治課不應(yīng)只局限于課堂上的教與學(xué)。把綜合探究課與研究性學(xué)習(xí)相結(jié)合,不失為一種有益的嘗試。傳統(tǒng)的學(xué)習(xí)方式把學(xué)習(xí)建立在客觀性、受動性、依賴性的基礎(chǔ)上,把學(xué)生看成一個沒有感情的接受容器,這種學(xué)習(xí)會窒息學(xué)生的思維和智力,成為學(xué)生發(fā)展的障礙。單元探究活動的開展就是要轉(zhuǎn)變學(xué)生的學(xué)習(xí)方式,關(guān)注學(xué)生的學(xué)習(xí)過程,使得探究過程成為學(xué)生發(fā)現(xiàn)問題、提出問題、分析問題、解決問題的過程,培養(yǎng)學(xué)生的創(chuàng)新精神和實踐能力。本教案的第一階段充分發(fā)揮了學(xué)生的主動性。

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.

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(rèn)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。
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)。
(五)平拋運動規(guī)律的應(yīng)用例1:一架老式飛機在高出海面45m的高處,以80m/s的速度水平飛行,為了使飛機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?不計空氣阻力。分析:對于這道題我們可以從以下幾個方面來考慮:(1)從水平飛行的飛機上投下的炸彈,做什么運動?為什么?(2)炸彈的這種運動可分解為哪兩個什么樣的分運動?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飛機離目標(biāo)的水平距離之間有什么關(guān)系?拓展:1、式飛機在高出海面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,不計空氣阻力。(1)判斷摩托車能否跨越壕溝?請計算說明(2)若能跨過,求落地速度?
3.進(jìn)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(jìn)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。
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(biāo)準(zhǔn)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(biāo)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(biāo)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(jìn)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(jìn)行力的分解。
