Listening and Speaking introduces the topic of “how to save endangered wildlife and help wildlife in their neighborhood.” Due to the continuous deterioration of the living environment, a large number of wild animals are always facing the threat of endangered or extinction. Listening and speaking period enables students to understand the fact and reason why wild species are disappearing from the earth at an amazing speed, and realize that human beings ought to enhance the awareness of protecting wild species as soon as possible.Listening and Talking introduces the theme of " how to help wildlife in Ss’ neighborhood.". Now there are many volunteers who spontaneously protect wild animals, carry out various activities according to local conditions, and contribute their own strength to local animal protection with practical actions. Middle school students are also enthusiastic participants. They organize activities in their spare time, and take this opportunity to make friends, broaden their horizons, cultivate team spirit and communication skills. This section describes a bird watching activity organized by several middle school students of Bird watching Club. It aims to stimulate students' interest, improve their understanding of bird watching activities, and use the language structure of “being used for; in order to, so as to, to, so that, in order that ” to express the purpose for communication and discussion.1. Guide students to understand the content of listening texts in terms of using visuals to predict content.2. Cultivate students' ability to guess the meaning of words in listening; discuss with their peers how to save endangered wildlife and help wildlife in their neighborhood.3. Instruct students to use functional sentences of the dialogue such as “I am concerned about…” “what do you know about the endangered animals in…" and so on to talk about one of the endangered animals.
This lesson is about wildlife protection. The listening and speaking is about “How to protect endangered wildlife ?” Faced with the facts and numbers of wildlife loss, people begin to detect the reasons, then people such as the celebrities (Prince William and Yao Ming) are calling on to protect them. So students are guided to enhance the awareness of protecting wildlife and try to take part in some volunteer activities of protecting wildlife.1. Predict the content by using visuals. 2. Learn to use the sentences such as “I’m concerned about.... But now they are in danger. I want to know the reasons/why./ What can we do to protect them ?3. Learn from the stars like Prince William and Yao Ming and enhance the awareness of protecting wildlife.4. Guide students to try to put forward the solutions to the problems of wildlife protection and then discuss them with partners and present the results of discussion.5. Master the pronunciation of stressed syllables.1. Learn from the stars like Prince William and Yao Ming and enhance the awareness of protecting wildlife.2.

Point at the pictures on P14 and ask Q1: What message do these posters share?
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,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,但是這一情況應以二者乘積等于額定功率為限度,即當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,應該在與轟炸目標的水平距離為多遠的地方投彈?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處,你認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的水平距離之間有什么關系?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,應該在與轟炸目標的水平距離為多遠的地方投彈?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以速度v=40m/s沿水平方向向另一側,壕溝兩側的高度及寬度如圖所示,摩托車可看做質點,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)學生動手、探究的習慣。2.體會實驗的意義,感受成功的快樂,激發(fā)學生探究問題的熱情、樂于學習的品質。教學重點1.體會牛頓第二定律在向心力上的應用。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。教學過程(一)、 引入新課:復習提問: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?學生回答后進一步引導: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?請同學們先閱讀教材
【教學設想】一、選題設想《巴黎圣母院》是雨果的代表作,無論從思想內容還是藝術風格都有明顯的浪漫主義特征:奇異曲折、扣人心弦的故事情節(jié);妙趣橫生、別出心裁的奇遇巧合;強烈鮮明的美丑、善惡對比;豐富生動、珠璣迸發(fā)、富有哲理意味的語言。通過導讀,來消除學生對外國名著的畏難情緒,增加學生課外閱讀的興趣和信心;讓學生整體把握作品,窺一斑而識全豹,讓學生高屋建瓴,了解其旨意,以極為精確而又充滿意蘊的文字,對名著的概述及精要部分做了介紹;引導學生自主探究,交流合作,培養(yǎng)學生的獨立思考的學習慣,指點進行名著閱讀的門徑。作為導讀課,教師應注意不可“越位”,在學生學習的過程中,教師的“導”固然重要,學生的“讀”更不可或缺,應避免以“導讀”來代替名著閱讀。因此,《巴黎圣母院》的教學定位為基于課內,面向課外,以求達到以學帶讀,以讀促學的目的。
2.表示現(xiàn)階段正在進行的被動動作(該動作在說話的瞬間未必正在進行)。Many interesting experiments are being carried out these days.(說話時,并不一定正在進行)3.表示一種經(jīng)常性的被動行為,常和always,constantly 等表示頻度的副詞連用,這種用法常常帶有贊揚或厭惡的感情色彩。He is always being praised by the leader.4.表示按計劃或安排主語將要承受謂語動詞所表示的動作(僅限于少數(shù)及物動詞)。A party is being held tonight.Step 4 Special cases1.像take care of, look after, talk about, think of等動詞與介詞構成的短語用于現(xiàn)在進行時的被動語態(tài)時, 其中的介詞不可省略。The ways to stop illegally hunting are being talked about. 2.可與部分情態(tài)動詞連用,表示對正在發(fā)生的事情的推測。She may be being punished by her mother.3.有時可表示按計劃或安排將要進行的一個被動動作。A celebration is being held this weekend for his success.4.某些表示“狀態(tài)、心理活動、存在”等的動詞,如have,want,need,love,一般不用現(xiàn)在進行時的被動語態(tài),而常用一般現(xiàn)在時的被動語態(tài)。With the population increasing,more land is needed.5.“be+under/in+n.”可表示現(xiàn)在進行時的被動意義。My computer is under repair.=My computer is being repaired.
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.
【設計思想】詩歌教學的關鍵是感受詩景,體味詩情,領悟詩意,在此基礎上孕育理解能力、鑒賞能力和審美情感。詩景、詩情、詩意均由文字來承載,把握文字組合的張力,是讀詩賞詩的抓手。杜甫的詩歌素以煉字精深、涵蓋深遠著稱,以《登高》而言,往往淡淡一字,平平一語,便籠大千于方寸,縮古今于一瞬。故細讀文本,咀嚼字句,便是賞景、悟情、會意的基本路徑。其次,不朽名作的特點是寄寓深廣,古今評價甚多,見仁見智,不一而足。這正是培養(yǎng)學生問題意識、探究意識的極好憑借。第三,詩為語言之精華,是詩人心里涌出的情感之流。誦讀乃賞詩之要著,精心感悟之時,設身處地,心惟口誦,是理解詩意的關鍵一步?;谑?,筆者作如下同課異構,殊途同歸。【教學目標】1.理解本詩所繪之景、所抒之情及繪景、抒情之法。2.學會用意象疊加法、字句推敲法、誦讀體驗法等欣賞詩歌。3.感受杜甫心系蒼生、情寄邦國、憂國憂民、兼濟天下的博大情懷。
“深入探究,把握主旨”這一步則是解決教學的重點難點,這里涉及到課文的深層意蘊,學生理解有難度,教師在通過問題引領學生探討的基礎上,還要適時啟發(fā)、點撥,因為教學時間有限,讓學生漫無邊際的討論,可能難以完成預定的教學任務,會使教學過程不完整。至于本文的寫作特點的教學視時間而定,有時間可以讓學生說一說,沒有時間用小黑板出示一下,讓學生了解就行,如果時間不夠,甚至可以不講。第三階段是“延伸練習,鞏固提高”。
一、說教材《短歌行》是普通高中課程標準實驗教科書必修(二)第二單元的一篇略讀課文,本單元安排的是先秦到南北朝時期的詩歌。《短歌行》是著名政治家、軍事家、文學家曹操的作品。詩中抓住“憂”字來寫詩人為什么“憂”,如何解“憂”,從而表達希望能夠招攬人才、完成統(tǒng)一天下的雄心壯志。所以本單元安排《短歌行》一詩,對學生全面了解曹操,感受曹操在短暫的人生中竭力創(chuàng)造偉業(yè)的氣概。二、說學生我這一課的教學對象是高一學生。他們進入高中學習的時間只有三個多月,現(xiàn)在已經(jīng)完成了必修(一)的學習。學習了現(xiàn)代詩歌單元,有了一定的詩歌學習基礎,初步掌握了讀詩的基本方法,但是還未能形成成熟的穩(wěn)定的學習方式。同時,本單元學習是高中第一次接觸古代詩歌,詩歌語言上的障礙和時間上的跨度對他們來說都是學習上的困難。因此教師要引導學生自主學習,合作學習,為他們設置新的學習情境,提供合作探究的機會。
1、教材的地位作用本課是新人教版普通高中歷史必修Ⅱ第六單元第18課的內容,闡述羅斯福新政的背景、措施、影響。從單元知識安排看,本課與第17課《空前嚴重的資本主義世界經(jīng)濟危機》、19課《戰(zhàn)后資本主義的新變化》共同詮釋第六單元課題——《資本主義世界經(jīng)濟政策的調整》。說明了“資本主義經(jīng)濟理論和政策隨著資本主義發(fā)展而不斷調整的特點”,凸顯了“市場調節(jié)”和“國家干預”在經(jīng)濟發(fā)展中的重要性。從知識體系看,它是學生學習了第一次工業(yè)革命后自由資本主義、第二次工業(yè)革命后的壟斷資本主義等之后出現(xiàn)的,既是對上述知識的鞏固與綜合運用,又為學生學習必修二的相關內容打下基礎,有承上啟下的作用。本課三個子目從邏輯上看又是遞進關系。第一個子目“臨危受命”承上啟下,說明了羅斯福上臺的歷史背景具有臨危受命的特點,第二個子目“實施新政”講述了羅斯福新政的主要內容,第三個子目“擺托危機困境”主要講述了羅斯福新政的影響。

(一)、復習提問1、請說出功的計算公式及功的單位2、我們用哪個物理量表示物體運動的快慢?(二)、創(chuàng)設情景,引入新課1、播放多媒體素材,用起重機和一個工人搬運幾百塊磚比較哪一種方法好?圖中的情景說明了什么問題?(教師通過所設計的情景,將學生引入怎樣比較做功快慢,讓學生發(fā)表自己的看法,初步知道物體做功是有快慢之分的。)(三)、進行新課1、比較做功快慢的方法播放多媒體素材并提出問題:怎樣比較兩個人誰做功快誰做功慢?教師啟發(fā):以前學習過要比較兩物體運動的快慢,可以先確定路程再比較時間,也可以先確定時間再比較路程。在路程和時間都不同時,通過計算速度比較兩物體運動的快慢。同理,要比較物體做功的快慢可采用什么方法?
探究一:高中階段功的含義是什么?投影:初中九年級《物理》105頁學生思考:①圖中物體的勢能、動能分別如何變化?②物體能量的變化和做功是否存在關系?學生:分組討論,得出結論:如果物體的能量發(fā)生變化時,說明有力對物體做了功。教師:進行點評和小結(設計意圖:對初中知識深化理論認識,并為以后功能關系的教學作準備)探究二:力對物體做功的兩個要素是什么?情景再現(xiàn):找體重相對懸殊的兩位同學,①A同學試圖抱起B(yǎng)同學,但沒成功。②B同學抱起A同學在教室內勻速走動。學生思考:在①中,A是否對B做功?在②中,B是否對A做功?學生:分析得出做功的兩要素:物體受到力的作用,并且在力的方向上發(fā)生位移.教師:讓學生分別例舉生活中力對物體做功和不做功的例子,(設計意圖:讓學生親身參與課堂實驗,烘托課堂氣氛,相互協(xié)作增進同學情誼)探究三:如果物體的位移不再力的方向上,那么力是否還對物體做功?
一、說教材1.教材分析《涉江采芙蓉》是新人教版必修二第二單元《古詩三首》中的一首?!豆旁娛攀住吩谥袊糯姼璧乃囆g手法上起著承前啟后的作用,在高中語文古詩教學中也起著承前啟后的作用。這首古體詩不論是藝術上,還是在思想上都已經(jīng)達到了十分純熟的境界。因此,它十分重要。2.說學情這首詩歌在內容上難度不大,可以做多角度解讀。新課程標準鼓勵學生作個性化解讀,我們可以引導學生就此作些探討。學生通過小學、初中的系統(tǒng)學習和本冊古詩部分的集中學習,有了一定的古詩鑒賞能力,對源遠流長的中華文化也有了一些積淀,興趣漸濃,這是進一步引導學生熱愛古代詩歌、學習古代詩歌的一個前提。3.教學目標依據(jù)學生特點,教材特色以及新課標的要求,制定教學目標如下:(用多媒體展示)1、了解關于《古詩十九首》的文學常識;2、感受詩歌的思想內涵;3、運用想象描摹詩歌的藝術畫面。

巴金在十年浩劫中的大致經(jīng)歷:放棄包弟并沒有換得保全一家人,1968年8月,巴金被關進牛棚改造,隨后經(jīng)受了大字報、掛牌游街等形式的批斗。1970年,到農(nóng)村改造,掏大糞、喂豬、背稻草、種地……1972年,妻子蕭珊在飽受精神折磨后患上癌癥,病逝。巴金的兒子在勞動改造的過程中也飽受精神和肉體上的折磨,性格變得內向抑郁,疾病纏身。此時,巴金69歲。巴金曾在《病中》一文寫道:“當姚文元拿著棒子的時候,我給關在牛棚里除了唯唯諾諾之外,敢于做過什么事情?十年間我不過是一條含著眼淚等人宰割的牛?!毙〗Y:(幻燈片12)社會是病態(tài)的社會,政治是高壓的政治,人性是扭曲的人性。十年文革,十年浩劫,給多少人留下了累累不可彌合的精神創(chuàng)傷。即使一條小狗,也可能擺脫不了“文革”無情的迫害,比如包弟,比如藝術家鄰居的小狗。
(1)主人公大衛(wèi)·科波菲爾:大衛(wèi)·科波菲爾是《大衛(wèi)·科波菲爾》中的主人公,曾經(jīng)是個孤兒。作家描寫了他從孤兒成長為一個具有人道主義精神的資產(chǎn)階級民主主義作家的過程。他善良,誠摯,聰明,勤奮好學,有自強不息的勇氣、百折不回的毅力和積極進取的精神,在逆境中滿懷信心,在順境中加倍努力,終于獲得了事業(yè)上的成功和家庭的幸福。在這個人物身上寄托著狄更斯的道德理想。(2)《大衛(wèi)·科波菲爾》中的女性形象:在狄更斯筆下,《大衛(wèi)·科波菲爾》塑造了一個個有血有肉的人物形象,每個任務都給人留下了深刻的印象,尤其是成功塑造了不同性格、不同品德的女性形象:貝西姨婆、艾妮斯、佩葛蒂、克拉拉、朵拉、摩德斯通小姐、米考伯太太、艾米麗……貝西姨婆與摩德斯通小姐的對比,克拉拉、朵拉與艾妮斯的對比更使她們栩栩如生,對貝西姨婆、艾妮斯、佩葛蒂的愛就更深一層,對摩德斯通小姐更是恨之入骨,對朵拉、克拉拉既同情又氣憤。
