③于是,大自然出現(xiàn)了驚人的奇跡,不毛的石縫間叢生出倔強(qiáng)的生命。④或者就只是一簇一簇?zé)o名的野草,春綠秋黃。歲歲枯榮。它們只有三兩片長長的細(xì)瘦的薄葉,那細(xì)微的葉脈,告知你生存該是多么艱難;更有的。它們就在一簇一簇瘦葉下自己生長出根須,只為了少向母體吮吸一點(diǎn)乳汁,便自去尋找那不易被覺察到的石縫。這就是生命,如果這是一種本能,那么它正說明生命的本能是多么尊貴,生命有權(quán)自認(rèn)為輝煌壯麗,生機(jī)竟是這樣地不可扼制。⑤或者就是一團(tuán)一團(tuán)小小的山花,大多又都是那苦苦的蒲公英。它們不似田野上的同宗長得那樣茁壯,它們的莖顯得堅(jiān)韌而蒼老。它們的葉因枯萎而失卻光澤。它們已經(jīng)不能再去為人們作佐餐的鮮嫩的野菜,卻默默地為攀登山路的人準(zhǔn)備了一個可靠的抓手。生命就這樣地被環(huán)境規(guī)定著,又被環(huán)境改變著,適者生存的規(guī)律盡管無情。但一切適者就是戰(zhàn)勝環(huán)境的強(qiáng)者。生命現(xiàn)象告訴你,生命就是拼搏。

Then I would ask them to think of a funny English or Chinese and tell it to partners. While telling stories, they can use expressions and some acting to help make the story funny. 5 minutes would be given to do this.Those stories they told there will be the material for their writing. Soletting them tell it at first is helpful. And they can make a difference between telling a funny story and writing it down. Generally speaking, it is difficult forstudents to write well because they don’t know what to write and how to write. Asking them to tell their own stories at first can help them come up with what to write.After their telling, I would invite someone to share his/her story with all of us and I would write it down on the blackboard.This example story would be used as a sample to illustrate the format of funny story. Different from a story from teacher or textbook, a story from students can obviously become a interesting material to draw students’ attention.Then I would ask the whole class to put this story into several parts. It might be a little bit difficult for them. So I would ask them to find out whether all the sentences are necessary. After delete some sentences, there are 6 sentences left behind. Then they can easily put them into three parts. After interaction with students, I would teach them the right terms for each part and conclude the format of funny story.This step is the key and difficult point in my lesson. So I mainly usetask-based teaching method in this part and the task for students was divided into several stages. With the separated difficult level, students can find there are usually three parts in writing. They can also learn to write without the unnecessary parts in the process of analyzing. And then I wouldn’t rush to tell them the right terms to them directly. Instead, I would ask them to name them by their own. A confused mind is better for acquiring knowledge.While-writing:Then I would give students 7 minutes to write down this story, without other requirements.With all the preparations in pre-writing, students’ difficulties were cleared. So it would be much easier for them to write down the story within 7 minutes. There are no other requirements because students’ first writing is actually a drafting. It would be revise and edit several times later. Writing, as a skill

Good afternoon, teachers, It’s my great pleasure to be here sharing my lesson with you.The content of my lesson is Senior English Book 3 Unit 5 Canada —— “The true North”.I’ll be ready to begin this lesson from five parts. Analysis of the teaching material,the teaching methods,the studying methods, the teaching procedure,and Blackboard design.First, let me talk about the teaching material.Part 1 Teaching Material:This unit is about the introduction of Canada. By studying of this unit,we’ll enable the students to learn the geography, population, main cities, and natural beauty, natural resources of Canada. Through the training of the unit, it also requires students to learn some Language skills such as the expressions of position and emotions.So it plays an important part in the English teaching in this book.After studying the teaching material and analyzing the rule of children’s growing of mind,I think the teaching aims are the followings:1.Knowledge objects:(1) make the students learn some new words and phrases(2) make the students understand the content of the lesson.2.Ability objects:(1)To develop the Ss’ abilities of listening, speaking, reading and writing. Especially reading and speaking ability.(2) learn to talk about the characters of Canada in English(3)To train the Ss’ ability of working in pairs.3.Emotion objects:(1)Enable students to understand the characters of Canada..(2)Stimulate Ss to work hard to make China stronger.Part 2 Teaching Methods:I think helping students learn to master new words and phrases and improve the students’ reading and speaking ability is import and the difficult.According to the analysis of the teaching material and the import points and the difficult points,I will use the following teaching methods : question-guiding approach; fast-reading and careful reading; multi-media teaching methods; discussion

通過寫文章梗概,培養(yǎng)學(xué)生綜合運(yùn)用語言的能力,學(xué)習(xí)用恰當(dāng)?shù)挠⒄Z描述科學(xué)家的故事。這是本課的教學(xué)難點(diǎn)。教師可以使用完形填空的方式來幫助學(xué)生整理語篇,從而來降低難度。本課的教學(xué)重點(diǎn)的突破方法是:在閱讀前,讓學(xué)生初步了解得出科學(xué)觀點(diǎn)所需要的基本程序,從而輕松而自然地導(dǎo)入文章的閱讀;在閱讀過程中,由易到難設(shè)計快速閱讀和精讀的問題,層層推進(jìn)各種閱讀活動,讓學(xué)生對閱讀內(nèi)容從整體感知到細(xì)節(jié)理解,最后深層讀懂整篇文章,同時加強(qiáng)閱讀策略的指導(dǎo),讓每個學(xué)生都主動參與課堂教學(xué)活動,最終達(dá)到提高閱讀能力的目的。Step 4 Post-readingGroup Activities四人小組共同合作,在老師的適當(dāng)指導(dǎo)下,就以下2個問題展開討論,讓學(xué)生就所知、所學(xué)、所感和所想融入話題,然后抽若干同學(xué)代表作小組發(fā)言。1. What do you think about John Snow, and what should we learn from him?2. Cholera was 19th century disease, which two diseases are similar to cholera today? Why?

今天我們來介紹一下必修五第四單元的授課方式。這個單元的題目是Making the news。應(yīng)該是學(xué)生比較感興趣的話題,學(xué)生往往對新聞工作充滿好奇,所以我們可以利用這個機(jī)會多設(shè)計一些師生互動和學(xué)生互動,來激發(fā)起學(xué)習(xí)的積極性,提高學(xué)習(xí)效率。同時我們可以利用這個單元不僅幫助學(xué)生掌握語言知識,培養(yǎng)語言能力,同時讓其了解新聞工作的重要性,培養(yǎng)起社會智能感。這個單元分為六個課時,它的教學(xué)目標(biāo)是這樣的:語言目標(biāo)是掌握詞匯表中的常用單詞和短語,掌握倒裝句的一些基本用法。 技能目標(biāo)是能初步掌握約會的基本句型并在真實(shí)的場景下正確運(yùn)用。新聞報道類文章的寫作技能。采訪的基本規(guī)范和溝通技能。情感目標(biāo)是對新聞報道的客觀性和真實(shí)性有更好的理解。對新聞記者的職業(yè)有更深入的了解,并能體會其工作的重要性。下面我們來介紹一下第一課時的授課方式,第一課的教學(xué)目標(biāo)是這樣的第一課時的教學(xué)目標(biāo)語言目標(biāo):單詞:Occupation, journalist, editor, photographer, curious, personality, enthusiasm

Let’s have a small test.Using the map on P9, students answer the following questions:?How many countries does the UK consist of? What are they??England is divided into three main areas. Do you know what they are? 1) Scanning (10Minutes )Let the students hold the questions asked in pre-reading and read the passagequickly and then let them do the following exercise.Join lines to the right answer.

Language learning needs a context, which can help the learners to understand the language and then can product comprehensible output, so computer has the advantages to make the materials attractive.Part 3 Learning MethodsTask-based, self-dependent and cooperative learningPart 4 Teaching ProcedureStep One Lead-in“Interest is the best teacher.” Therefore, at the very beginning of the class, I should spark the students’ mind to focus on the centre topic “the band”. I’ll show some pictures of food to attract their attention and then bring some questions.Question:What kind of food they like?What should go into a good meal?The answers must relate to the diet. After this, the students will be eager to know something about a balance diet and this is the very time to naturally lead the class into Step 2Step 2 Reading for information: skimming and scanning In this step, I use Task-based Language Teaching method, which can give students a clear and specific purpose while skimming and scanning the context.Task 1 General ideaThe students will be asked to just glance at the title and the pictures of the passage, and then guess what they will read in the text. And they’ll be divided into groups of four to have a discussion.The purpose is to inspire the students to read actively, not passively. In addition, the task is to develop the students’ reading skill by making prediction and to encourage the students to express their thoughts in English and cooperate with each other.Task 2 Main idea of each paragraphCooperative learning can raise the students’ interest and create an atmosphere of achievement. Based on this theory, I divide the whole class into 4 groups to skim the whole text and get the main idea of each paragraph.

同學(xué)們,為了我們健康活潑地成長,讓我們攜起手來,從我做起,從小事做起,共同創(chuàng)造一個美好的生活環(huán)境。相信我們的校園會更美,我們的家園——地球會水更清、天更藍(lán)。4月份國旗下講話稿4篇 尊敬的老師,親愛的同學(xué)們:早上好!這個星期三就是清明節(jié)了,很多人都要回家祭祖掃墓了?!扒迕鲿r節(jié)雨紛紛,路上行人欲斷魂.”說的就是每當(dāng)這個特殊的時候,人們都會倍加思念已經(jīng)死去的親人,心情難免傷感。今天在這莊嚴(yán)的升旗儀式上,我們凝視著烈士鮮血所染的國旗,不覺思緒又回到那艱苦崢嶸的歲月:舊中國飽受戰(zhàn)爭的創(chuàng)傷和帝國主義的欺凌,人民受盡磨難和屈辱。舊上海的公園門口曾立著一塊醒目的牌子,上面寫著“華人與狗不得入內(nèi)?!蓖鈬喆邳S浦江上肆意闖蕩,撞翻中國民船,淹死中國人也不管。那時洋人在中國土地上為所欲為,國人已喪失了最起碼的做人尊嚴(yán)。祖國危難之時,無數(shù)愛國志士挺身而出,為了祖國的獨(dú)立統(tǒng)一和人民的解放,甘灑一腔熱血。從不惜千金買寶刀,貂裘換酒也堪豪的女俠秋瑾,到一腔熱血勤珍重,灑去猶能化碧濤的鄒容;從江姐到劉胡蘭;從黃繼光到董存瑞……無數(shù)英烈用他們的生命,譜寫了一曲曲壯烈的愛國樂章。難道他們不知道生命的可貴嗎?不!他們非常珍惜自己的生命,但是他們深深懂得:在祖國危亡之時,作為一個中國人,保衛(wèi)祖國,拯救祖國是自己的責(zé)任,為了祖國的解放,先烈們拋頭顱灑熱血,戰(zhàn)火中出生入死,監(jiān)牢里堅(jiān)貞不屈,刑場上大義凜然。他們用生命、熱血換來了華夏民族的新生。英烈們雖打下了江山,但他們的事業(yè)還沒有完成。與發(fā)達(dá)國家相比,中國依然貧窮落后。為了圓民族的強(qiáng)盛夢,讓先烈的理想變成現(xiàn)實(shí),每個炎黃子孫責(zé)無旁貸地?fù)?dān)負(fù)起建設(shè)富強(qiáng)祖國的歷史重任。是的,目前中國還窮,正因?yàn)槿绱耍判枰覀儊黹_拓建造一個美麗的家園。美國曾經(jīng)也很窮,美國牛仔當(dāng)年開發(fā)西部時也絕沒有可口可樂,但他們的后代沒有抱怨、觀望,更沒有逃避和背叛??恐淮忠淮说呐?,他們富強(qiáng)起來了。清貧的中國正需要這樣的硬氣,繼承先烈遺志,實(shí)現(xiàn)先烈遺愿,我們唯有臥薪嘗膽,自強(qiáng)不息。誰不想自己的祖國日益強(qiáng)大呢?誰不想在走出國門時可以驕傲地稱自己是中國人呢?祖國是民族的根,愛國是民族的魂。世界上任何一個偉大的民族都把愛國作為自己精神的支信和力量的源泉。

一、導(dǎo)入部分: 談話:小朋友們早上好,今天范老師要和小朋友一起來玩一個游戲,在玩游戲之前,小朋友先告訴我10以內(nèi)的單數(shù)都有誰?10以內(nèi)的雙數(shù)都有誰? 二、基本部分: 1、游戲名稱:跳單雙 ①教師介紹游戲規(guī)則:今天我們小朋友身上都系有漂亮的絲帶,那小朋友看一看你們的絲帶有什么不同?(顏色不同)那我們系紅絲帶的小朋友圍成一個圈,系黃絲帶的小朋友在紅絲帶小朋友的外面再圍一個大圈,小朋友手插腰跳,里面的小朋友往外跳,外面的往里跳,按照老師的的口令來回的跳反復(fù)進(jìn)行,直到老師說:“?!眲t立即停下,老師檢查完絲帶就可以判斷出你跳的是單數(shù)還是雙數(shù),你們相信嗎?﹙教師要說的神秘一些引發(fā)幼兒的好奇心和興趣﹚②游戲過程:教師喊口令幼兒做游戲,提醒幼兒遵守游戲規(guī)則,并對犯規(guī)的幼兒及時提醒。 ③教師總結(jié):為什么老師能說出你們誰是單數(shù),誰是雙數(shù)呢?接下來我們一起來聽一個故事,聽完這個故事你們就知道了。﹙引起幼兒的好奇心﹚

1.統(tǒng)計是數(shù)學(xué)課程標(biāo)準(zhǔn)規(guī)定的四個領(lǐng)域之一。傳統(tǒng)上比較注重統(tǒng)計圖表等知識和根據(jù)統(tǒng)計圖表回答問題的教學(xué),而課程標(biāo)準(zhǔn)則更加重視學(xué)生對數(shù)據(jù)統(tǒng)計過程的體驗(yàn),學(xué)習(xí)一些簡單的收集、整理和描述數(shù)據(jù)的方法,認(rèn)識統(tǒng)計的作用和意義。這部分內(nèi)容比較繁瑣,分小組進(jìn)行合作學(xué)習(xí)是有效的學(xué)習(xí)方式。2.教師將教科書的盆花變成紙花,努力為學(xué)生創(chuàng)設(shè)一些數(shù)據(jù),使教材更具有實(shí)用性。但是,對于有條件的學(xué)校,可以帶領(lǐng)學(xué)生進(jìn)行實(shí)地統(tǒng)計,效果會更佳。3.教師要善于捕捉課堂上學(xué)生的反饋信息,創(chuàng)設(shè)輕松愉悅的課堂氣氛。本課中,教師設(shè)計的讓學(xué)生學(xué)四種動物的叫聲,不僅活躍了課堂氣氛,又引入到下一個問題的探討。4.充分尊重學(xué)生的選擇,讓學(xué)生用自己喜歡的方法進(jìn)行統(tǒng)計,使他們的情感、態(tài)度在其中得到了充分體驗(yàn)。

統(tǒng)計是一種數(shù)學(xué)思想,也是認(rèn)識客觀事物常用的一種方法。讓學(xué)生學(xué)習(xí)統(tǒng)計,要引導(dǎo)他們經(jīng)歷收集、整理數(shù)據(jù)的過程,精力把整理出來的數(shù)據(jù)用圖表形式表現(xiàn)出來的過程,經(jīng)歷對統(tǒng)計的數(shù)據(jù)進(jìn)行分析、判斷的過程,從中理解并掌握一些有關(guān)統(tǒng)計的基礎(chǔ)知識和基本技能,學(xué)習(xí)解決實(shí)際問題。(一)新的課程標(biāo)準(zhǔn)要求我們的數(shù)學(xué)課程應(yīng)體現(xiàn)基礎(chǔ)性、普及性和發(fā)展性。要強(qiáng)調(diào)從學(xué)生已有的生活經(jīng)驗(yàn)出發(fā),要使學(xué)生學(xué)有價值的數(shù)學(xué),這些內(nèi)容要有利于學(xué)生主動地進(jìn)行觀察、實(shí)驗(yàn)、猜測、驗(yàn)證、理解與交流等數(shù)學(xué)活動。(二)本課的教學(xué)通過學(xué)生積極參與數(shù)學(xué)活動,合作交流,力求體現(xiàn)人人學(xué)有價值的數(shù)學(xué),體現(xiàn)數(shù)學(xué)就在我們的身邊,與我們的學(xué)習(xí)生活緊密相聯(lián),體會統(tǒng)計的目的和意義,掌握統(tǒng)計的方法,體驗(yàn)數(shù)學(xué)學(xué)習(xí)的樂趣。

三、制作統(tǒng)計圖教師:事先我們一起搜集了這幾年中我們班同學(xué)家庭擁有計算機(jī)的情況,并制成了統(tǒng)計表,請誰來介紹一下。(學(xué)生利用事先制成的統(tǒng)計表介紹數(shù)據(jù))如果請你將它制作一份折線統(tǒng)計圖,你有信心完成嗎?小組討論:你認(rèn)為在制圖時應(yīng)做哪些工作?有什么注意點(diǎn)?(學(xué)生小組討論后交流)在交流中,教師順應(yīng)學(xué)生回答,并相應(yīng)介紹折線統(tǒng)計圖各部分名稱:(1)橫軸:一般用于標(biāo)明日期的前后;(2)縱軸:標(biāo)明數(shù)據(jù),反映單位長度表示的數(shù)據(jù)大小,一般最高數(shù)據(jù)比統(tǒng)計到的最高數(shù)據(jù)稍高一些;(3)制表日期和單位。學(xué)生獨(dú)立在練習(xí)之上嘗試練習(xí)。教師指名演示,同學(xué)互相評價并改正。統(tǒng)計分析:從這張統(tǒng)計圖上你可以獲得哪些信息?學(xué)生相互交流,也可以提問請同學(xué)回答。

四,說教學(xué)過程(一)基本功訓(xùn)練:通過2分鐘口算練習(xí)以及聽,說,動的訓(xùn)練,提高學(xué)生的口算能力及運(yùn)算速度,培養(yǎng)學(xué)生的聽,說,動的學(xué)習(xí)習(xí)慣.緩解學(xué)生的緊張情緒.(二)情景激趣,導(dǎo)入新課.通過談話,同學(xué)們喜歡吃水果嗎吃水果能吃出數(shù)學(xué)問題.這是出示例1的情境圖,讓學(xué)生說一說他們吃出了什么數(shù)學(xué)問題.這樣設(shè)計的意圖是通過學(xué)生自己觀察發(fā)現(xiàn)數(shù)學(xué)信息,提出數(shù)學(xué)問題,培養(yǎng)學(xué)生解決問題的意識和能力,培養(yǎng)學(xué)生抓住有價值的數(shù)學(xué)信息的能力.(三)探究同分母分?jǐn)?shù)加法.看到黑板上的和你想到了什么(比大,分母相同,根據(jù)這個分?jǐn)?shù)你們能提個問題嗎)這是注重培養(yǎng)學(xué)生多思考,多表達(dá),在語言表達(dá)中深化對前面學(xué)習(xí)過知識的理解.發(fā)展學(xué)生的語言表達(dá)能力.

3、教材結(jié)構(gòu)分析教材內(nèi)容可以看出,本節(jié)課包含四個知識的內(nèi)容。即調(diào)查入學(xué)時的體重情況填寫統(tǒng)計表;收集現(xiàn)在(二年級)的體重情況填寫統(tǒng)計表;把入學(xué)以及現(xiàn)在的體重情況統(tǒng)一填寫到同一個統(tǒng)計表中;整理、分析表內(nèi)信息回答簡單的問題。但從本地學(xué)生情況實(shí)際出發(fā),以及條件的限制,所以本人對教材內(nèi)容進(jìn)行了略微的調(diào)整,將調(diào)查入學(xué)時的體重情況填寫統(tǒng)計表改為統(tǒng)計本地區(qū)天氣情況,也與現(xiàn)實(shí)生活緊密地聯(lián)系在一起。同時,按照教材的邏輯性將知識整合在新課程改革的目標(biāo)中。4、教學(xué)目標(biāo)(1)知識目標(biāo):能運(yùn)用信息的手段、新的學(xué)習(xí)方法收集整理數(shù)據(jù)完成簡單的復(fù)合式統(tǒng)計圖。(2)情感目標(biāo):能根據(jù)統(tǒng)計圖表中的數(shù)據(jù)提出并解答簡單的問題,感受生活中處處有數(shù)學(xué),結(jié)合實(shí)例有機(jī)地進(jìn)行家鄉(xiāng)情的教育。

(設(shè)計意圖:撥開云霧見天日。在學(xué)生自主探究后,利用多媒體教學(xué)課件,結(jié)合學(xué)生的生活實(shí)際,動態(tài)演示兩種計時法的對應(yīng)關(guān)系,充分調(diào)動學(xué)生多種感官參與學(xué)習(xí)的過程,提高了學(xué)習(xí)效率。)2、探究兩種計時法的互換方法師問:“同學(xué)們看著鐘面,能很快找到了兩種計時法對應(yīng)的時間,那沒有了鐘面,你能發(fā)現(xiàn)他們之間互換方法嗎?”同學(xué)們通過觀察發(fā)現(xiàn)普通計時法前面都有表示時間的詞語,比如上午、下午、晚上,而24時計時法卻沒有這些;經(jīng)過思考總結(jié)出由普通計時法向24時計時法轉(zhuǎn)化時要去掉表示時間的詞語,中午12時之后要加上12,中午12時之前不用加,反之由24時計時法向普通計時法轉(zhuǎn)化時,要加上表示時間的詞語,中午12時之后要減去12,中午12時之前不用減。
