(二)分析課文,理清思路第1、2段為第一部分,主要是敘事、寫景,先敘述集會的時間、地點,然后渲染出蘭亭優(yōu)美的自然環(huán)境。在這里足以“游目騁懷”“極視聽之娛”,可以自由地觀察、思考,滿足人們目視耳聞的需求。這里正是與會“暢敘幽情”、盡興盡歡的絕好處所。這些描寫都富有詩情畫意,作者的情感是輕松愉快的。第3、4段為第二部分,主要是抒情、議論,作者由美景妙時引發(fā)出樂與憂、生與死的感慨。他認為人生的快樂是有極限的,待快樂得到滿足時,就會感覺興味索然。往事轉(zhuǎn)眼間便成為歷史,人到了生命的盡頭就會死亡。作者由“一死生為虛誕,齊彭殤為妄作”的認識,產(chǎn)生了一種珍惜時間、眷戀生活、熱愛文明的思考。雖然文中的壽夭、生死不能自由決定,從而有些傷感,但作者仍然認識到盛衰、生死是必然的。人生無常,時不我待,故著文留傳后世,以承襲前人,啟示來者。
探究、討論、交流:1、包弟討人喜歡,作者卻不得不將它送走,為什么?2、送走包弟后,作者為什么先是感覺輕松,隨后覺得沉重?3、“您的小狗怎樣?”這句話反復出現(xiàn),有什么用意?4、“整整十三年零五個月過去了”“整整”一詞有什么作用?5、“滿園的創(chuàng)傷使我的心仿佛又給放在油鍋里熬煎”這句話如何理解?6、“我懷念包弟,我想向它表示歉意。”如何理解?學生各抒己見后教師結(jié)合材料發(fā)表看法明確總結(jié)特別是最后一個問題得出作者這發(fā)之心底的語言,不僅僅是歉意,更是發(fā)自靈魂深處的懺悔!是對生命的尊重,是一個有良知的作家對反省歷史的呼號。第三環(huán)節(jié)“認識你自己”——懺悔意識與我引導學生正視和反省成長過程中曾犯下過錯。并布置課后作業(yè):要求學生課后在本周隨筆中談反省懺悔后的感受。
(1)“問君西游何時還……使人聽此凋朱顏。”詩題下未注明送何人入蜀,所以這里的“問君”無妨假定實有其人,可以讀得親切一些。將行而問“何時還”,已有不可行之意,重音要落在“不可攀”三字上,當用勸說的語氣讀。以下四句借鳥聲渲染旅途中悲涼凄清的氛圍,讀時要放低聲調(diào),有干里孤身之感,至“愁空山”徐徐而上。然后用感喟的語調(diào)讀主旨句,至“凋朱顏”略作一頓,以示意猶未盡。(2)“連峰去天不盈尺……胡為乎來哉!”仍是說不可行,但內(nèi)容加深了一層,因為說的是蜀道的險惡。前四句不是純客觀的描寫,讀時須設(shè)想這是旅游者攀援于“連峰”“絕壁”之上置身于“飛湍瀑流”之間,要使聽者感到驚心動魄。讀后可作稍長停頓,再用“其險也如此”緩緩收住。末句是詩人借用蜀人的口氣,對歷險而來的游者深表嘆息——“胡為乎來哉”不是詢問,當用降調(diào)讀,暗含“何苦而來”之意。
各位評委老師,大家好。我說課的題目是《祝福》。一、說教材(一)教材所處的位置和地位高中語文新課程教材必修五本書,共有2個單元中外小說單元。一個必修3的第一單元,一個是必修5的第一單元,共六篇文章。(《林黛玉進賈府》《祝?!贰独先伺c海》《林教頭風雪山神廟》《裝在套子里的人》《邊城》)《祝?!肥菍儆谇罢摺P≌f是擁有眾多讀者的一種文體,它可以多方面刻畫人物性格,描摹人物心理,完整地表現(xiàn)人物之間的沖突,還可以具體生動地再現(xiàn)人物生活的環(huán)境,因此在反映復雜的社會生活方面具有獨特優(yōu)勢。所以學習小說這種文學樣式,也是有助于學生學會鑒賞小說的基本方法,為將來的小說閱讀打下基礎(chǔ)。魯迅的《祝?!肥侵袊F(xiàn)代小說的精品,當中的人物祥林嫂也是魯迅小說中與阿Q、孔乙己三個最為出名的人物之一。研讀好這篇文章,對將來小說的閱讀,小說中人物的理解,甚至小說的寫作都有深廣意義。
四、說教學程序(一).溫故知新、導入新課復習提問:基因突變導致生物變異的原因是什么?回答:基因突變是基因結(jié)構(gòu)發(fā)生改變,從而使遺傳信息改變,使蛋白質(zhì)結(jié)構(gòu)改變、生物性狀改變,即生物發(fā)生了變異。那么,基因是什么?它和染色體又有何關(guān)系?回答:基因是有遺傳效應的DNA片斷,染色體是DNA的載體,基因在染色體上呈線形排列。引出新知:對于一個生物體來說,正常情況下,其染色體的結(jié)構(gòu)和數(shù)量都是穩(wěn)定的。但在自然條件或人為因素的影響下,染色體的結(jié)構(gòu)和數(shù)量均會發(fā)生改變,從而導致生物性狀的改變,這就屬于染色體變異。(二).把握重點、突破難點重點的把握:1、染色體結(jié)構(gòu)的變異播放影片:貓叫綜合征幼兒。讓學生觀察: 患兒哭聲輕、音調(diào)高,很像貓叫。教師補充: 患兒的征狀---兩眼較低、耳位低下,存在著嚴重的智力障礙。闡述病因---染色體片段缺失
(3)v. 給:提出;展現(xiàn),顯現(xiàn)present sb. with sth. ; present sth. to sb. 把. . 交給;頒發(fā);授予present sth. (for sth. )/present sth. to sb. e. g. Om his birthday, his friends presented him a collection of stamps. 在他生日時,他的朋友們送給他一套郵票作為禮物。The sword was presented by the family to the museum. 這家人把寶劍捐贈給了博物館。The committee will present the final report to Parliament in June. 委員會將在六月向議會提交最后的報告。You need to present yourself better. 你需要更善于展現(xiàn)自己。It is essential that we present a united front. 至關(guān)重要的是我們要表現(xiàn)得更加團結(jié)。Step 4 ConsolidationT:Now that we have got a general idea of these words and phrases. Lets make up some sentences using them to master them. Suggested sentences:1. Your duties include typing letters and answering the telephone. 2. It is one of the greatest roles that she has played. 3. A large number of people have applied for the job. 4. The number of the panda is declining. 5. I'11 go there, even if I have to walk. 6. He came up to me to ask for a light. 7. The novel is about a family who can't communicate with each other. 8. He based his plan on interests of most people. 9. Why doesn't he make use of his singing talent?Step 5 Summary and homeworkT:Today we dealt with several new words and phrases. After class I hope that youcan read them again and again to keep them in mind. That's all for today. You aredismissed.
In this step, give students a few minutes to read the passage . While they are reading, I will write some key words of the text on the blackboard. Then ask students to retell the passage according to the key words.By retelling, students can improve their ability of language organization and have an overall understanding of the article.Step 4 Group discussionIn this step, students will be divided into groups of 4 to discussion the following question: What qualities make a great person?After their discussion, invite a few groups to make a report to the class.This group discussion can practice students’ oral English and cultivate their abilities of cooperation and communication.Step 5. HomeworkLet students write a short passage to introduce a great person he or she admires.The homework can consolidate the knowledge the students have learned and cultivate their writing ability. Part 6 Blackboard Design(板書設(shè)計)That’s all my teaching procedures. Finally, I’d like to say sth about part 6 blackboard design. On the top is the title. On the left, there will be some new words and expressions. In the middle of the blackboard, I will write some useful sentence structures so that the students can know clearly what they’ve learned and then try to master the knowledge.OK. That’s all for my presentation. Thank you for your attention.
一. 教材分析1. 本單元的中心話題是“計算機(Computers)”,內(nèi)容涉及計算機的發(fā)展歷史,計算機的應用等。本節(jié)課是該單元的第一課時,我將Warming up, Pre-reading and Comprehending這四部分整合為一節(jié)精讀課。其中。Reading部分是題為WHO AM I?的文章,以第一人稱的擬人手法介紹了計算機發(fā)長演變的歷史和計算機在各個領(lǐng)域的應用,其主旨是表達計算機的發(fā)展變化之快以及在生活中用途之廣。而Warming up部分以圖片的形式展現(xiàn)了計算機的發(fā)展歷程;Pre-reading中的問題和排序分別是為了預測語篇的內(nèi)容和測試學生對計算機歷史了解的情況;Comprehending則通過各項練習訓練學生的閱讀技能,從而加深對文章的理解??梢娺@幾部分是一個有機的整體。2. 教學目標:1) 語言目標:重點詞匯及短語:abacus, calculate, calculator, PC, laptop, PDA, robot, analytical, technological, universal, mathematical, artificial, intelligent, network, explore, in common, as a result.重點句子:a. My real father was Alan Turing, who in 1963 wrote a book to describe how computers could be made to work, and build a “universal machine” to solve any mathematical problem.
Step 2 Pre-listeningAfter students finish their discussion, I will show a picture of Newton and ask them: Who is him? What is he famous for? Could you find out some words to describe him? Maybe students will answer that he is genius for his finding of theGravitation, making a great contribution to the progress of human being. At that time I will show another two pictures of Einstein and Hawking, letting students guess who they are and write down their idea about the Gravitation. For I have arranged them to search more information about the gravity before this class, Students have beenfamiliar with the topic and will not be afraid about this abstract conception, which is helpful for their listening.Step 3 While-listeningIn this step, students will be required to listen the material for three times. The first and listening is extensive listening and the second and third listening is intensive listening. In the first time, They are required to listen a material including Part 1 and Part 2 and choose the best summary of the listening text. After they choose the right answer, They also need work in group to explain what is wrong with the others. Then I will make a conclusion that we should pay attention to the first paragraph and last paragraph and some keys to get the main idea. By doing this, their capacity of generalization will have a great improvement.Before the second listening, I will ask students to scan the blank on the power point quickly and ask them to note down some key words .Then ask them to listen to the Part 1again and fill the first column of the chart. Maybe some students just show the ideas of these three scientists an still can’t catch their development of gravity. Therefore, I will ask them to listen to Part 2 again and fill in the rest. After finish the listening, I will give them ten minutes to discuss with their partner. I will also guidethem to improve their answers when they discuss with others.
When it comes to the students’ studying methods, I'd like to introduce my Ss first. The Ss have a good command of basic language points. They’re interested in learning English, and they take an active part in English class, so they will have fun in autonomous, cooperative and inquiry learning. I will just serve as a guide, showing them the way to explore how to make more progress in their English learning.Now it’s time for the most important stage of this lesson. My teaching procedures are arranged as follows:Step1.Leading-in (3 minute)Play a video of a wide variety of wildlife to introduce my topic. Step2. Speaking (12 minutes)We will use our textbook Page25. Let the Ss fast read the short paragraph to warm up. Ask them to talk about the report on some endangered wildlife in China with the dialogue patterns on the screen. Lastly, I will invite some groups to demonstrate their dialogues about saving wildlife in China.Step3.English play (3 minutes)Watch another video in praise of their excellent performance just now. It’s about Jack Chen’s(成龍)and Yang Ziqiong’s wildlife protection.Step4. Listening (twice 13 minutes)This time, I’ll ask the Ss to fill in the blanks of the monologue of the 2 movie stars above. Step5.Discussion (3 minutes)Which would you like to choose to wear, clothes made of cotton, artificial leather or animal skins? Why ?Step6. Summary (3 minutes)1. If there were no wildlife, there wouldn’t exist human beings. If the buying stops, the killing can, too.2. Animals are our friends. To love animals is to love ourselves. Stop hunting, killing and destroying wildlife.3. Let’s live in harmony with all the living things in the world. Step7. Music appreciation (3 minutes)Let the Ss appreciate the song Earth Song by Michael Jackson. Last but not the least, I will show you my blackboard design.
Good afternoon, everyone. It’s my great pleasure to be here sharing my lesson with you. The content of my lesson is Senior English for China Book5 Unit 3 Life in the Future. I’ll be ready to begin this lesson from six parts: Analysis of the teaching material, Analysis of the students, Teaching aims and important and difficult points, Teaching methods and aids, Teaching procedures, and Blackboard design. First, let me talk about the teaching material.Part 1 Analysis of the Teaching Material:This unit is about what human beings’ life will be like in about one thousand years. By studying of this unit, we’ll Enable the students to know the changes in humans’ life and some new inventions bringing about the change and develop the interest in science. This lesson plays an important part in the English teaching in this unit. This is an important lesson in Book Five. From this lesson, it starts asking the Ss to grasp contents of each passage. Therefore, this lesson is in the important position of the teaching material. If the Ss can learn it well, it will be helpful to make the Ss learn the rest of this unit.Part 2 Analysis of the SsAs Senior2 Ss, they are at different levels of English fluency, some of them have lost interest in English. So during the lesson, I arrange a variety of activities to let all of them join in to attract their interest and let them be confident and taste the joy of success.
設(shè)計意圖:幾道例題及練習題,其中例1小車由靜止啟動開始行駛,以加速度 做勻加速運動,求2s后的速度大???進而變式到:小車遇到紅燈剎車……,充分體現(xiàn)了“從生活到物理,從物理到社會”的物理教學理念;例題及練習題由淺入深、由易到難、各有側(cè)重,體現(xiàn)新課標提出的讓不同的學生在物理上得到不同發(fā)展的教學理念。這一環(huán)節(jié)總的設(shè)計意圖是反饋教學,內(nèi)化知識。(6) 小結(jié)歸納,拓展深化我的理解是,小結(jié)歸納不應該僅僅是知識的簡單羅列,而應該是優(yōu)化認知結(jié)構(gòu),完善知識體系的一種有效手段,為充分發(fā)揮學生的主題作用,從學習的知識、方法、體驗是那個方面進行歸納,我設(shè)計了這么三個問題:① 通過本節(jié)課的學習,你學會了哪些知識;② 通過本節(jié)課的學習,你最大的體驗是什么;③ 通過本節(jié)課的學習,你掌握了哪些學習物理的方法?
培養(yǎng)學生合作交流意識和探究問題的能力,這一部分知識層層遞進,符合學生由特殊到一般、由簡單到復雜的認知規(guī)律。4、互動探究(1)極限思想的滲透讓學生閱讀“思考與討論”小版塊.培養(yǎng)學生的自學和閱讀能力提出下列問題,進行分組討論:a、用課本上的方法估算位移,其結(jié)果比實際位移大還是小?為什么?b、為了提高估算的精確度,時間間隔小些好還是大些好?為什么?針對學生回答的多種可能性加以評價和進一步指導。讓學生從討論的結(jié)果中歸納得出:△t越小,對位移的估算就越精確。滲透極限的思想。通過小組內(nèi)分工合作,討論交流,培養(yǎng)學生交流合作的精神,以及搜集信息、處理信息的能力;通過小組間對比總結(jié),使學生學會在對比中發(fā)現(xiàn)問題,在解決問題過程中提高個人能力;
(三)合作交流能力提升教師:剛才我們通過實驗了解了小車的速度是怎樣隨時間變化的,但實驗中有一定的誤差,請同學們討論并說出可能存在哪些誤差,造成誤差的原因是什么?(每個實驗小組的同學之間進行熱烈的討論)學生:測量出現(xiàn)誤差。因為點間距離太小,測量長度時容易產(chǎn)生誤差。教師:如何減小這個誤差呢?學生:如果測量較長的距離,誤差應該小一些。教師:應該采取什么辦法?學生:應該取幾個點之間的距離作為一個測量長度。教師:好,這就是常用的取“計數(shù)點”的方法。我們應該在紙帶上每隔幾個計時點取作一個計數(shù)點,進行編號。分別標為:0、1、2、3……,測各計數(shù)點到“0”的距離。以減小測量誤差。教師:還有補充嗎?學生1:我在坐標系中描點畫的圖象只集中在坐標原定附近,兩條圖象沒有明顯的分開。學生2:描出的幾個點不嚴格的分布在一條直線上,還能畫直線嗎?
昨天就是母親節(jié),不知道各位同學有沒有像自己母親說一句母親節(jié)快樂呢?亦或是幫母親做做家務,捶捶背?說實話,我也是直到昨天中午才想起來還是因為我在寫這篇演講稿。感恩母親,這是一個非常老的話題,但也是最令人觸動的話題。說起最親的人,恐怕就是同學們各自的父母。古人說身體皮膚,受自父母。我們現(xiàn)在說有的東西都是父母給的。也許你說,成績是你自己努力得來的,但如果沒有父母的支持,你能有這個努力的機會嗎?也許你會說,你經(jīng)常去剪頭發(fā)并以此來調(diào)侃我,但你剪頭發(fā)的錢,是你父母的吧?而一家之中,父親為生計而奔波,陪伴在你身邊做多的就是你的母親。 沒有任何一種付出是無償?shù)?,除了愛,特別是母親。母親只期望自己的孩子能夠過上更好的生活,并為此付出自己的一切。而我們甚至不需要報答,只要自己活得好好的就足以讓母親安心,正如有篇關(guān)于海子的文章,“好好活著就是愛”。 但同學們,你們能不去報答嗎?或者說,你們的良心能允許你們不去報答嗎?你們難道可以就這么自己享樂,任母親去辛勞嗎?摘錄一節(jié)我喜歡的文章。
春天的原野撒滿了鮮花,春天的天空充滿了希望,在這個美麗的春天里,送一份禮物給自己吧,它會改變你的世界!什么禮物這么神奇?它就是——你的微笑。曾經(jīng)有一個愁眉苦臉的男孩來求助一位長者,“我是一個成績不好,又沒有人愛的孩子,活著真沒意思!”長者送給他一塊石頭,要他拿到集市上賣,但無論別人出多少錢,都不要賣。第二天,男孩蹲在市場的一個角落,面前擺著那塊石頭,果然有人向他打聽那塊石頭,而且價錢越出越高?;貋砗?,男孩興奮地向長者報告,長者笑了笑,要他明天拿著石頭再到黃金市場上去賣。在黃金市場,竟有人喊出比昨天高出十倍的價錢要那塊石頭。后來,男孩又把石頭拿到寶石市場上去展示,結(jié)果,石頭的身價又漲了十倍。由于男孩怎么也不肯賣,這塊普通的石頭竟被傳為“稀世珍寶”。
第八周國旗下講話稿:把握自己遠離網(wǎng)吧老師們、同學們:今天我講話的題目是《把握自己遠離網(wǎng)吧》。我先給大家講個故事。一只蜘蛛向年輕的蚊子打招呼:“小伙子,到我家里歇歇吧,我家可好了?!蔽米诱f:“我才不來呢,誰不知道你那兒是要命的陷阱?!敝┲胝f:“如今我開網(wǎng)吧了,那真叫過癮,你快來試試吧?!蔽米勇犃诉@話,便一頭扎了進去……結(jié)果,大家可想而知?,F(xiàn)在,隨著信息技術(shù)的發(fā)展,網(wǎng)絡(luò)就像蜘蛛網(wǎng)一樣,延伸到了社會生活的各個角落。它給我們帶來了許多方便,我們可以在網(wǎng)上查閱資料、瀏覽到最新消息;網(wǎng)絡(luò)還可以開闊我們的視野,促進我們的學業(yè)。然而,我們也應該清醒地認識到,網(wǎng)絡(luò)是把“雙刃劍”,它給我們帶來巨大便利的同時,也給我們帶來了巨大的負面影響。尤其是在一些黑網(wǎng)吧內(nèi),一些不良的信息,低俗的內(nèi)容,刺激的游戲,給你們造成的危害將更大。同學們,你們知道嗎?XX年6月21日,北京“藍極速”網(wǎng)吧發(fā)生特大火災,大火燒死了24人。24條年輕的生命就這樣喪生在這個黑網(wǎng)吧內(nèi)!據(jù)有關(guān)部門調(diào)查,現(xiàn)在社會上有90%的網(wǎng)吧是“黑”網(wǎng)吧。這些網(wǎng)吧里面沒有任何安全設(shè)施,極易發(fā)生安全事故。
第二周國旗下講話-給自己一個目標各位老師、各位同學:大家好,今天我講話的題目是:給自己一個目標。度過一個愉快的暑假,我們在初秋的氣息中迎來了新的學期。積蓄了一個假期的自信與激情,踏入濃濃書香氣息的校園,我們可曾想過:這學期,我的奮斗目標是什么?這學期,我想獲得的進步是什么?這學期,我會為此做出哪些努力?這學期,我準備怎樣讓自己更快樂?1993年,一個14歲的孩子在上海青年籃球隊里打球,當時球隊里的隊員都穿著帆布面的籃球鞋。有一次,他在觀看一場國外球隊的比賽時發(fā)現(xiàn),那些國外的球員竟然都穿著皮制的籃球鞋。這種球鞋不但美觀,而且穿著舒適。于是,這個孩子夢想能穿上一雙皮制的籃球鞋。 一天,當他把這個夢想告訴教練后,教練笑著說:“努力吧,孩子,如果你能進入國家青年隊,你就能穿這樣的鞋?!睆倪@一刻起,這個孩子就把進入國家青年隊作為自己奮斗的目標。終于在17歲那年,他憑借自己超凡的球技被選入國家青年隊。穿上了夢想已久的皮制籃球鞋,他倍加珍惜。一位隊友發(fā)現(xiàn)此事后告訴他:“不用在意一雙球鞋,如果你能進入國家隊,這樣的籃球鞋你想有多少就有多少。”這句極具誘惑力的話深深震撼著他,于是,他又有了新的奮斗目標:中國國家籃球隊。
四.設(shè)計反思我在設(shè)計本課時,希望通過情境的創(chuàng)設(shè)充分再現(xiàn)歷史,并利用多媒體輔助教學,破重點、化難點,讓學生主動參與到學習過程中,從而突破狹小的教室空間,讓學生真正做到感知歷史,立足現(xiàn)實,展望未來。自主,交流、合作、探究是課程改革中著力倡導的新型學習方式。課堂教學中如何開展小組合作的探究學習存在著很多困難,首先是課堂教學時間有限,如何體現(xiàn)面向全體,給每個學生以機會?再次,歷史問題的討論只能依托于史料才能使討論不淪為空談,課堂上通過網(wǎng)絡(luò)提供大量的史料(文字、圖片或其他),勢必不能有充分時間讓學生閱讀分析。如何解決這些問題呢?措施一:要形成較固定的歷史學習合作小組。選定一位同學擔任組長,負責協(xié)調(diào)措施二:要設(shè)置有利于學生探究的問題情境措施三:要把課堂教學與課外學習結(jié)合起來。在課前就印發(fā)相關(guān)的材料,或引導學生去查閱相關(guān)的資料,讓學生有個充分的閱讀、思考、交流的時間,是保證課堂上小組交流能成功實現(xiàn)的一個前提
研究一種物理現(xiàn)象,總是要先從現(xiàn)象的描述入手。機械運動作為自然界最簡單和最基本的運動形態(tài),它所描述的是物體空間位置隨時間變化的情況。因此,本節(jié)學習描述質(zhì)點做機械運動需要時刻、時間間隔和位移等概念。相當一部分高一學生在具體過程中難以區(qū)別時刻和時間間隔。另外,由于思維的定式,在第一次接觸既要考慮大小又要考慮方向的問題時,會因不適應造成學習困難。所以,區(qū)別“路程與位移”“時刻和時間間隔”是教學的重難點所在。學習這些內(nèi)容的過程與方法對學習速度和加速度可以起到奠定基礎(chǔ)的作用。教學的對象是高一的學生,這一時期的學生處在好奇善問、創(chuàng)新意識強烈的青少年期。對于生活中出現(xiàn)的各種現(xiàn)象具有濃厚的興趣。但他們的思維還停留在簡單的代數(shù)運算階段,對于矢量和矢量運算的理性認識幾乎沒有。且對生活中出現(xiàn)的時間、時刻、時間間隔等不能做出很好的區(qū)分,對時常提及的路程、距離等形成了模糊的前概念。
