在講述細(xì)胞分化的意義時(shí),也可以用實(shí)例來(lái)解決,工廠的生產(chǎn)車間里不同的工人干著不同的工作,一件產(chǎn)品的產(chǎn)出需要這些工人才能創(chuàng)造出來(lái),一個(gè)生物體就像一個(gè)車間一樣,不同的細(xì)胞各司其職,相互合作。工人的分工是主管調(diào)解出來(lái)的,而不同細(xì)胞的出現(xiàn)就是細(xì)胞分化的結(jié)果,所以說(shuō),細(xì)胞的分化是生物體發(fā)育的基礎(chǔ)。在講到細(xì)胞全能性的時(shí)候,要多給學(xué)生舉些關(guān)于細(xì)胞全能性的例子,如植物組織培養(yǎng)、克隆技術(shù)等等,讓學(xué)生從實(shí)際的例子中真正的悟出細(xì)胞全能性的含義。此外,還要重視教材中的疑問(wèn),適當(dāng)對(duì)題目進(jìn)行引申,使它的作用更加突出,有利于學(xué)生對(duì)知識(shí)的串聯(lián)、積累、加工,從而達(dá)到舉一反三的效果。怎樣來(lái)解釋細(xì)胞的全能性呢?這主要以講授法來(lái)解釋了,細(xì)胞全能性的體現(xiàn)需要在組織或器官離體后才能體現(xiàn)出來(lái),每個(gè)細(xì)胞都包含著生物體的全套遺傳基因,通過(guò)基因選擇性的表達(dá),使離體的組織或器官通過(guò)分裂和分化逐漸發(fā)育成完整的植株。

四、說(shuō)教學(xué)程序(一).溫故知新、導(dǎo)入新課復(fù)習(xí)提問(wèn):基因突變導(dǎo)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(yīng)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(duì)于一個(gè)生物體來(lái)說(shuō),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(huì)發(fā)生改變,從而導(dǎo)致生物性狀的改變,這就屬于染色體變異。(二).把握重點(diǎn)、突破難點(diǎn)重點(diǎn)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(xué)生觀察: 患兒哭聲輕、音調(diào)高,很像貓叫。教師補(bǔ)充: 患兒的征狀---兩眼較低、耳位低下,存在著嚴(yán)重的智力障礙。闡述病因---染色體片段缺失

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.

Purpose of my design:To ask the students to do these two tasks will make the Ss predict the story of this passage. As a result, it will deepen Ss’ memory of this story because they will have their own understanding of this story.Step 3. While-readingTask 1. (Individual work _____min)Skimming: ask students to skim the text and the main ideas of each paragraph in this passage. Please read it quickly and then match the sentences with the letters.Task 2. (Individual work _____min)Scanning: read the text quickly and decide the whether the following statements are true or false and give reasons.Task 3. (Pair work _____min)Listen to the tape and fill in the banks. Then read the paragraph with expression to your partner.Task4 (individual work min)Listen to the tape again and write down the main idea in one sentence.Purpose of my design: Enable students to understand the given material better by using different reading skills. And proper competition can arouse the Ss’ interest in English learning. “Task-based” teaching method is used here todevelop the Ss’ ability of communication and also their ability of co-operation will be well trainedStep 4. Post-readingTask 1. (Individual work, pair work, group work, class work; _____min)Discussion (group of 4):1. If you were Hippomenes, would you run against Atlanta?2. Do you think Hippomenes deserved to win the race? Why or why not?Step 5. HomeworkPlease read the story again carefully after class and imagine: What will happen during the race between Hippomenes and Atlanta? Who do you think will win the race? Do you think Atlanta would marry Hippomenes? Write an end for the story with thses questions.Purpose of my design: Homework is so important and necessary for to master the knowledge they learned after class. It will check whether the Ss achieve the teaching aims.Part 5 Blackboard design

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.

Teaching plan for Unit 1 book3Good morning, teachers. It’s my great pleasure to be here because I can share my lesson with you and I can learn a lot from it. I’ll begin my lesson from the following four parts, the teaching material, the teaching methods, the studying methods and the teaching procedure.Firstly, let me talk about the teaching material. The content of my lesson is the reading passage festivals and celebrations of Unit 1 Festivals around the world. This passage is about festivals and celebrations. By studying this passage, we’ll enable the students to know that festivals exit everywhere, and many of festivals in different countries celebrate similar ideas. As we all know, the reading passage is the center of each unit. If the Ss can learn it well, it will be helpful to make the Ss learn the rest of this unit.After studying the teaching material, I think the teaching aims are as the followings:1. Knowledge aims:(1) The Ss can master the usage of the important words andexpressions.(2)The Ss can use the __________________ (grammar) in the proper situation.Make students know about the festivals all over the world and the detail of the festivals, such as origin, content, and the date of the holiday festivals.2. Ability aims:(1) Students can talk about festivals and celebrations in English(2) To improve the student’s reading ability, especially their skimming and scanning ability.3. Emotion aims:Make the Ss know about the foreign festivals, and respect other countries’ custom.Next, let’s come to the important points and the difficult points.The important point is how to make the Ss understand the text better and the difficult point is how can they talk about it. secondly, Teaching Methods:1. task-based Language Teaching2. Computer assisted language teaching.3. question-and–answer methodThirdly, Studying Methods:

In this class, I have 3 teaching aims, that is, knowledge aims, ability aims and emotion aims.1) Knowledge-Teach students new words and expressions, such as temporary, bleed,sprain choke, first aid, fall ill and so on.-Enable students to have a better understanding for some basic knowledge of first aid.2) Ability-Train students’ speaking, reading and writing abilities by different teaching activities, such as skimming, comprehending, team work, role play, retelling and writing.-Develop students’ reading strategy on how to move general idea to specific information.3) Emotion-Promote students’ awareness of giving first aid.- Cultivate students’ creativities.Then let’s come to my teaching methods and activities.III. Teaching methods and activities:To achieve different teaching aims, various kinds of teaching methods and activities will be adopted throughout this period, such as TBL (task-based learning), skimming, team work, brainstorm and others, which can offer students opportunities to fulfill tasks in which they can use language to achieve a specific outcome.IV. Teaching aids:Computer and blackboardV. Teaching important points:1) Make students have a clear mind for the structure of the text.2) Help students understand the theme of the text.VI. Teaching difficulties:1) So many new words may affect students’ understanding.2) How to get students to know about the functions of the skin and thecauses, characteristics and treatments for different degree burns,and the knowledge about giving first aid. VII. 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.

一、教材分析1、教學(xué)對(duì)象分析《再別康橋》的教學(xué)對(duì)象是高一學(xué)生,高一學(xué)生往往對(duì)那種純粹的、原始的、本真的情感體會(huì)較為膚淺,《再別康橋》是新月派詩(shī)人徐志摩的傳世之作,有極高美學(xué)價(jià)值,它所抒發(fā)的離愁別緒是人類共同的情感經(jīng)歷,通過(guò)誦讀容易將學(xué)生帶人詩(shī)境,喚醒他們沉寂的真情,從而引起強(qiáng)烈的共鳴。 2、教材地位及作用 高中語(yǔ)文第一冊(cè)第一單元為詩(shī)歌單元,本單元收錄了中國(guó)現(xiàn)當(dāng)代的一些優(yōu)秀詩(shī)篇?!对賱e康橋》安排在本單元的第二課,屬于必讀課。雖然本詩(shī)向來(lái)眾說(shuō)紛紜,但其藝術(shù)之美人所共知,培養(yǎng)學(xué)生高尚的審美情趣和良好的審美創(chuàng)造力是語(yǔ)文學(xué)科的任務(wù),因此,從語(yǔ)言賞析入手,從情感體驗(yàn)切入,就可以讓學(xué)生通過(guò)學(xué)習(xí)本課體會(huì)現(xiàn)代詩(shī)歌的特點(diǎn),多方面感受體悟詩(shī)歌的情感,受到美的熏陶。

四、教學(xué)方法和學(xué)法。課前學(xué)生搜集有關(guān)《詩(shī)經(jīng)》的資料必不可少。另外,時(shí)隔數(shù)千年,年代久遠(yuǎn),文字的障礙很大,然而,過(guò)分糾纏于文字的疏通會(huì)破壞詩(shī)歌的“氣”,喪失詩(shī)歌的“神”,所以在學(xué)習(xí)時(shí),應(yīng)舍去條分縷析的理論評(píng)價(jià),指導(dǎo)學(xué)生結(jié)合注釋疏通文字,然后引領(lǐng)他們經(jīng)由文字再現(xiàn)形象和事件,經(jīng)由形象和事件領(lǐng)略情感,感受其中濃濃的詩(shī)情。誦讀的環(huán)節(jié)是重要的,配以二胡獨(dú)奏《長(zhǎng)相思》,營(yíng)造意境,學(xué)生沉浸在音樂(lè)營(yíng)造的意境中反復(fù)吟詠,讀出節(jié)奏,讀出音調(diào),讀出感情,細(xì)細(xì)體味,讓或優(yōu)或喜的情愫縈繞心間,我們就觸到了先民的靈魂。比興手法為《詩(shī)經(jīng)》獨(dú)創(chuàng),重章疊句同樣別致而新鮮,教學(xué)過(guò)程中結(jié)合具體語(yǔ)境讓學(xué)生自己去發(fā)現(xiàn)并進(jìn)行討論,不搞枯燥的知識(shí)傳授。還引入講故事、改寫(xiě)兩種活潑的學(xué)習(xí)形式,從而達(dá)到加深理解的目的。

一、說(shuō)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(shī)三首》中的一首。《古詩(shī)十九首》在中國(guó)古代詩(shī)歌的藝術(shù)手法上起著承前啟后的作用,在高中語(yǔ)文古詩(shī)教學(xué)中也起著承前啟后的作用。這首古體詩(shī)不論是藝術(shù)上,還是在思想上都已經(jīng)達(dá)到了十分純熟的境界。因此,它十分重要。2.說(shuō)學(xué)情這首詩(shī)歌在內(nèi)容上難度不大,可以做多角度解讀。新課程標(biāo)準(zhǔn)鼓勵(lì)學(xué)生作個(gè)性化解讀,我們可以引導(dǎo)學(xué)生就此作些探討。學(xué)生通過(guò)小學(xué)、初中的系統(tǒng)學(xué)習(xí)和本冊(cè)古詩(shī)部分的集中學(xué)習(xí),有了一定的古詩(shī)鑒賞能力,對(duì)源遠(yuǎn)流長(zhǎng)的中華文化也有了一些積淀,興趣漸濃,這是進(jìn)一步引導(dǎo)學(xué)生熱愛(ài)古代詩(shī)歌、學(xué)習(xí)古代詩(shī)歌的一個(gè)前提。3.教學(xué)目標(biāo)依據(jù)學(xué)生特點(diǎn),教材特色以及新課標(biāo)的要求,制定教學(xué)目標(biāo)如下:(用多媒體展示)1、了解關(guān)于《古詩(shī)十九首》的文學(xué)常識(shí);2、感受詩(shī)歌的思想內(nèi)涵;3、運(yùn)用想象描摹詩(shī)歌的藝術(shù)畫(huà)面。

一.教材理解教材地位與作用:本單元“閱讀與鑒賞”部分,本單元要求學(xué)生能在了解詩(shī)歌創(chuàng)作的時(shí)代背景的情況下通過(guò)反復(fù)誦讀詩(shī)歌,把握其中豐富的意象,領(lǐng)悟詩(shī)歌獨(dú)特的意境和詩(shī)人所要表達(dá)的情感?!队晗铩肥乾F(xiàn)代派大師戴望舒的成名作和前期的代表作,他曾因此而贏得了“雨巷詩(shī)人”的雅號(hào)。本單元以《雨巷》為例子給學(xué)生展示了象征主義詩(shī)歌的特點(diǎn),《雨巷》運(yùn)用了象征性的抒情手法。詩(shī)中那狹窄陰沉的雨巷,在雨巷中徘徊的獨(dú)行者,以及那個(gè)像丁香一樣結(jié)著愁怨的姑娘,都是象征性的意象。這些意象又共同構(gòu)成了一種象征性的意境,含蓄地暗示出作者即迷惘感傷又有期待的情懷,并給人一種朦朧而又幽深的美感。富于音樂(lè)性是《雨巷》的另一個(gè)突出的藝術(shù)特色。詩(shī)中運(yùn)用了復(fù)沓、疊句、重唱等手法,造成了回環(huán)往復(fù)的旋律和宛轉(zhuǎn)悅耳的樂(lè)感。因此我把本課的教學(xué)重點(diǎn)和難點(diǎn)確定為:教學(xué)重點(diǎn):通過(guò)反復(fù)誦讀,領(lǐng)略詩(shī)歌的音樂(lè)美以及分析其成因教學(xué)難點(diǎn):分析意象以及其象征意義初步掌握鑒賞詩(shī)歌的方法

一、導(dǎo)入新課人類社會(huì)越來(lái)越現(xiàn)代化,新科學(xué)技術(shù)日新月異,令人目不暇接,稱之到了“知識(shí)爆炸”的時(shí)代也毫不為過(guò)。由此而來(lái)的是生活的快節(jié)奏,學(xué)習(xí)和工作的競(jìng)爭(zhēng)也越來(lái)越激烈。這種競(jìng)爭(zhēng)一直波及到了兒童,加之中國(guó)幾千年來(lái)形成的望子成龍的傳統(tǒng)觀念,使作父母的把一切希望都寄托在孩子身上,實(shí)現(xiàn)自己未能實(shí)現(xiàn)的理想。祖孫三代4、2、1的局面,使12只眼睛都盯在了孩子身上,真是走路怕摔著,吃飯怕噎著,干活怕累著,要星星不敢摘月亮,要吃什么跑遍全城也要買來(lái)。這種過(guò)分保護(hù)、溺愛(ài)及過(guò)早地灌輸知識(shí)會(huì)得到什么結(jié)果呢?樂(lè)觀者說(shuō)孩子越來(lái)越聰明,越來(lái)越早熟,將來(lái)能更好適應(yīng)現(xiàn)代化的要求;悲觀者則認(rèn)為豆芽菜式的孩子將來(lái)經(jīng)不起風(fēng)浪,小皇帝太多了很難凝聚成統(tǒng)一力量,將來(lái)誰(shuí)去當(dāng)兵,誰(shuí)去干那些艱苦創(chuàng)業(yè)性工作……。對(duì)孩子本身來(lái)說(shuō),是幸福還是……在此不想多發(fā)議論,還是讓我們來(lái)看看動(dòng)物世界的孩子們吧,也許會(huì)得到某種啟迪。

本文篇幅較長(zhǎng),并且有一字句不易理解,因而對(duì)高一學(xué)生來(lái)說(shuō)完全讀懂內(nèi)容有一些困難。這樣的話,老師就要做好引導(dǎo)工作,把一些難點(diǎn),或是出現(xiàn)詞類活用比較多,局勢(shì)比較特殊的句子,老師可以先給學(xué)生畫(huà)出來(lái),存疑,或是與同學(xué)們一起討論解決。對(duì)那些不易懂的字詞就引導(dǎo)學(xué)生聯(lián)系上下文提供的語(yǔ)境、前后涉及的情節(jié)加以推測(cè)、判斷,以培養(yǎng)學(xué)生依據(jù)文脈推斷詞義的好方法。要求學(xué)生點(diǎn)出重點(diǎn)實(shí)詞、框出通假字,主要是為幫助學(xué)生積累和掌握一些文言文中常見(jiàn)的一詞多義、異讀現(xiàn)象、古今異義和通假現(xiàn)象的詞語(yǔ),并進(jìn)一步得出規(guī)律,指導(dǎo)今后的文言文學(xué)習(xí)。詞類活用和特殊句式在文言文翻譯中難度較大,也是本文教學(xué)的兩大難點(diǎn)。要求學(xué)生標(biāo)出有活用現(xiàn)象的字和劃出句式特殊的句子,是基于兩點(diǎn)考慮:1、積累一定數(shù)量的第一手例句;2、引導(dǎo)學(xué)生加以分類,找出每類的相同特征,并抽取出來(lái)形成規(guī)律性的東西,從而上升到理性認(rèn)識(shí),使學(xué)生能由學(xué)會(huì)一個(gè)到會(huì)學(xué)多個(gè)。翻譯過(guò)程中注重指導(dǎo)學(xué)生養(yǎng)成用符號(hào)法表示重點(diǎn)字句的好習(xí)慣,如點(diǎn)、框、圈、劃線等符號(hào)應(yīng)約定一致,便于突出翻譯中的重點(diǎn)、難點(diǎn)及復(fù)習(xí)。我的提示著重歸納了實(shí)詞“制”“亡”“遺”“利”等,名詞活用、形容詞活用、使動(dòng)用法,被動(dòng)句、狀語(yǔ)后置句。

(1)“問(wèn)君西游何時(shí)還……使人聽(tīng)此凋朱顏。”詩(shī)題下未注明送何人入蜀,所以這里的“問(wèn)君”無(wú)妨假定實(shí)有其人,可以讀得親切一些。將行而問(wèn)“何時(shí)還”,已有不可行之意,重音要落在“不可攀”三字上,當(dāng)用勸說(shuō)的語(yǔ)氣讀。以下四句借鳥(niǎo)聲渲染旅途中悲涼凄清的氛圍,讀時(shí)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(yǔ)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(lái)哉!”仍是說(shuō)不可行,但內(nèi)容加深了一層,因?yàn)檎f(shuō)的是蜀道的險(xiǎn)惡。前四句不是純客觀的描寫(xiě),讀時(shí)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(tīng)者感到驚心動(dòng)魄。讀后可作稍長(zhǎng)停頓,再用“其險(xiǎn)也如此”緩緩收住。末句是詩(shī)人借用蜀人的口氣,對(duì)歷險(xiǎn)而來(lái)的游者深表嘆息——“胡為乎來(lái)哉”不是詢問(wèn),當(dāng)用降調(diào)讀,暗含“何苦而來(lái)”之意。
