學生初步了解對話內容,在描述中培養(yǎng)學生的語言運用能力。(2)教師讓學生自己閱讀本部分對話,不理解的生詞和句子可以和同學或老師共同商討。(3)教師幫助學生理解句子:“The weather report says it’s going to rain tomorrow. I can’t play football in the rain. I can’t go hiking, either. Let’s watch TV together.”出示圖片:1) 晴天,Zoom在踢足球,圖下顯示:today;2)天在下雨,Zoom和Zip在屋里看電視,圖下顯示:tomorrow。與學生展開對話T:What’s the weather like today? S:It’s fine/ sunny. T:What does the weather report say about tomorrow?S:It’s going to rain.T:The weather report says it’s going to rain tomorrow.(呈現(xiàn)句子)(學生重復句子The weather report says it’s going to rain tomorrow.,并說出意思。)T:Can you play football in the rain?S:No,I can’t.T:Can you go hiking ?S:No,I can’t.T:In the rain, we can’t play football. We can’t go hiking, either. (呈現(xiàn):either)學生跟讀either,感悟單詞的用法,教師講解意思:(不......),也不...啟發(fā)學生用either說兩句話:In the rain, I can’t ... I can’t ..., either,從而在應用中鞏固單詞的讀音和用法。

區(qū)分賓語從句、定于從句和狀語從句賓語從句和狀語從句,都叫做主從復合句。賓語從句主要是中考必考的,是初中階段必掌握的從句,賓語從句主要是掌握三要素,所謂賓語從句,就是賓語在主從復合句當中充當賓語的一個句子,叫做賓語從句。主句的謂語動詞是及物動詞,后面如果是詞或者是短語的話,是簡單句,如果是句子的話,肯定是賓語從句。I know that he good at English.就是賓語從句,三要素,一要素是要注意連詞,連詞一共學了三類連詞,一類連詞是that口語當中可以省略,就像剛才說的那一句,I hear he is good at English.還有疑問代詞、疑問副詞,how where when,疑問代詞、疑問副詞。還有一類連詞weather是否的意思,不是狀語從句當中的如果,這一定要和如果區(qū)分開,這是是否。I don't know if he interested at English。賓語從句要注意if是連詞。第二要素是語序,要用陳述舉語序。比如說你家有幾口人,我們都說How many people are there in you family?但是這是簡單句,一旦說成賓語從句,你可以告訴我你家有幾口人嗎?Could you tell me how many people there are in you family ?
"Hello! Welcome to English class! Introduce yourself. Meet your new classmates." That's what the teacher says. What do you say? "Oh no!" It can be difficult talking to new people. But it can be fun, and you can make friends. How do you do it? Make small talk. Small talk is polite conversation. "Wang Nan is a great pingpang player, isn't she?" "I'd love to meet her, wouldn't you?" "It's been raining a lot, hasn't it?" Tag questions are a form of polite speech. To make small talk successfully, you should know how to make them. You should also know what topics to talk about. Try to learn this unit carefully. The next time you're in English class, you'll find out. Making small talk's easy, isn't it? (“你好!歡迎你!請做一下自我介紹。認識一下你的新同學?!蓖ǔT谡n上老師會這樣說。你會說什么呢?“噢,不!”與陌生人談話太困難了。但是這也很有意思,并且你還能交到朋友。你該怎么做呢?閑聊。閑聊指得是禮貌的對話?!巴蹰且粋€很棒的乒乓球運動員,不是嗎?”“我希望自己能認識她,你呢?“今年的雨水很多,不是嗎?”反意疑問句是一種禮貌用語。為了使得談話成功,你應該知道怎樣去進行閑聊。你還應該知道與不同的人該談論什么樣的話題。認真的學習這個單元吧,下次在英語課上,你會發(fā)現(xiàn)與大家展開談話是一件很容易的事情,不信我們來試試。)
(一).知識方面: 1.培養(yǎng)學生能運用過去進行時來描述、談論過去某個時間正在發(fā)生的事情或動作的意識和能力,能就過去某個時間正在發(fā)生的動作做出正確的描述。 2.培養(yǎng)學生的想象力和角色扮演的合作能力。 3.培養(yǎng)學生講述過去發(fā)生的事情經(jīng)過的能力。能正確運用一般過去時來講述故事。 (二).技能方面: 1.本單元的語言目標是Talk about past events and tell a story(談論過去的時間和講述一個故事),圍繞這一目標,要涉及句型: What were you doing when the UFO arrived? ----I was sitting in the barber’s chair. The barber was cutting my hair. 因此必須學習standing、studying、cleaning、sleeping、cooking、making、eating、cutting、等表示地點的詞,以便為上述句型提供語言材料。2.學習過去進行時的有關知識。Was/were+現(xiàn)在分詞,是該時態(tài)的表達式。 3.在學習過程中,要區(qū)分The boy was walking down the street when the UFO landed.和While the boy was walking down the street, the UFO landed.這兩種由when和while引導的狀語從句的句型結構。注意它們的不同。
教師帶領學生復習有關描述寵物的詞匯,采用教師提問學生回答的方進行。如:T:What animals do you think would be good pets?What animals do you think would be bad pets?What do you think are good animals for a six-year-old child?然后學生進行 pairwork 練習。Task two: 師生互動,學習探究 1、播放3a部分的錄音,引導學生一邊聽錄音,一邊跟讀。2、通過聽錄音學生回答以下問題:Why do you think pot-bellied pigs are popular?What are the advantages and disadvantages of keeping such a pet?教師對學生的回答進行及時點評。3.學習范文,學習重點短語,為下步的模仿寫作提供語言素材。T :1. )Have you ever kept a pig as a pet?Do you like pigs? St.:No.…Why don’t you like to keep a pig? St: No.They’re too dirty and lazy(Do you know in some foreign countries like Hollyland, Australia,pigs are the most popular pet.there’s a kind of pig.(圖)it has an interesting name? it ‘s called a pot-bellied pig.) Now,let’s learn an article about this kind of interesting pet.2.)play the tapeSt.:Listen and repeat3.)show some Qs on computer(本子St.: read silently,then answerthe Qs(本子)4.)Ask ss.

Step Ⅱ Show the new words on the screen and teach the new words. Read the new words to students and ask them to repeat.Step Ⅲ 3aThis activity introduces new vocabulary and provides reading practice using the target language.In this activity first look at the four pictures.T: What can you see in the pictures?Ss: Four snow globes.T: Right. There are four snow globes in the pictures. And what are they?Ss: They are a monster, two polar bears, two penguins and a birthday cake.Write these words on the blackboard: snow globe; monster; polar bear; penguin and birthday cake. Read them to the class and ask students to repeat each one. Make sure students understand each word.Use a computer to show the E-mail message on the screen and read the message to students.Get students to read the e-mail on their own, and then draw lines connecting each snow globe and its description.Correct the answers.AnswersA line should connect each snow globe picture with the words that describe it in the letter.Step Ⅳ 3bThis activity provides writing practice using the target language.First review Activity 2a on Page 47.Then ask students to complete the message according to Activity 2a.Some partial sentences are given to students. Write about one person's collection.When students work, walk around the room checking the progress and offering help as needed.When they finish, ask some students to read their messages to the class.
把解集在數(shù)軸上表示出來,并將解集中的整數(shù)解寫出來.解析:分別計算出兩個不等式的解集,再根據(jù)大小小大中間找確定不等式組的解集,再找出解集范圍內的整數(shù)即可.解:x+23<1 ①,2(1-x)≤5 ②,由①得x<1,由②得x≥-32,∴不等式組的解集為-32≤x<1.則不等式組的整數(shù)解為-1,0.方法總結:此題主要考查了一元一次不等式組的解法,解決此類問題的關鍵在于正確解得不等式組或不等式的解集,然后再根據(jù)題目中對于解集的限制得到下一步所需要的條件,再根據(jù)得到的條件進而求得不等式組的整數(shù)解.三、板書設計一元一次不等式組概念解法不等式組的解集利用數(shù)軸確定解集利用口訣確定解集解一元一次不等式組是建立在解一元一次不等式的基礎之上.解不等式組時,先解每一個不等式,再確定各個不等式組的解集的公共部分.
有三種購買方案:購A型0臺,B型10臺;A型1臺,B型9臺;A型2臺,B型8臺;(2)240x+200(10-x)≥2040,解得x≥1,∴x為1或2.當x=1時,購買資金為12×1+10×9=102(萬元);當x=2時,購買資金為12×2+10×8=104(萬元).答:為了節(jié)約資金,應選購A型1臺,B型9臺.方法總結:此題將現(xiàn)實生活中的事件與數(shù)學思想聯(lián)系起來,屬于最優(yōu)化問題,在確定最優(yōu)方案時,應把幾種情況進行比較.三、板書設計應用一元一次不等式解決實際問題的步驟:實際問題――→找出不等關系設未知數(shù)列不等式―→解不等式―→結合實際問題確定答案本節(jié)課通過實例引入,激發(fā)學生的學習興趣,讓學生積極參與,講練結合,引導學生找不等關系列不等式.在教學過程中,可通過類比列一元一次方程解決實際問題的方法來學習,讓學生認識到列方程與列不等式的區(qū)別與聯(lián)系.
方法總結:已知解集求字母系數(shù)的值,通常是先解含有字母的不等式,再利用解集唯一性列方程求字母的值.解題過程體現(xiàn)了方程思想.三、板書設計1.一元一次不等式的概念2.解一元一次不等式的基本步驟:(1)去分母;(2)去括號;(3)移項;(4)合并同類項;(5)兩邊都除以未知數(shù)的系數(shù).本節(jié)課通過類比一元一次方程的解法得到一元一次不等式的解法,讓學生感受到解一元一次不等式與解一元一次方程只是在兩邊都除以未知數(shù)的系數(shù)這一步時有所不同.如果這個系數(shù)是正數(shù),不等號的方向不變;如果這個系數(shù)是負數(shù),不等號的方向改變.這也是這節(jié)課學生容易出錯的地方.教學時要大膽放手,不要怕學生出錯,通過學生犯的錯誤引起學生注意,理解產生錯誤的原因,以便在以后的學習中避免出錯.
安裝及運輸費用為600x+800(12-x),根據(jù)題意得4000x+3000(12-x)≤40000,600x+800(12-x)≤9200.解得2≤x≤4,由于x取整數(shù),所以x=2,3,4.答:有三種方案:①購買甲種設備2臺,乙種設備10臺;②購買甲種設備3臺,乙種設備9臺;③購買甲種設備4臺,乙種設備8臺.方法總結:列不等式組解應用題時,一般只設一個未知數(shù),找出兩個或兩個以上的不等關系,相應地列出兩個或兩個以上的不等式組成不等式組求解.在實際問題中,大部分情況下應求整數(shù)解.三、板書設計1.一元一次不等式組的解法2.一元一次不等式組的實際應用利用一元一次不等式組解應用題關鍵是找出所有可能表達題意的不等關系,再根據(jù)各個不等關系列成相應的不等式,組成不等式組.在教學時要讓學生養(yǎng)成檢驗的習慣,感受運用數(shù)學知識解決問題的過程,提高實際操作能力.
三、說教學目標1.認識“曾、蒙”等13個生字;會寫“鋒、昨”等9個生字。2.引導學生一邊朗讀一邊想象,通過有感情地朗讀,理解課文,體會雷鋒叔叔的奉獻精神。3.引導學生通過讀書感悟“哪里需要獻出愛心,雷鋒叔叔就出現(xiàn)在哪里”的深刻含義。四、說教學重難點 1.培養(yǎng)學生搜集資料的能力,通過感悟雷鋒事跡,懂得奉獻愛心,樂于助人。(重點)2.引導學生通過讀書感悟“哪里需要獻出愛心,雷鋒叔叔就出現(xiàn)在哪里”的深刻含義。(難點)五、說教法和學法1.朗讀感悟法,本文語言優(yōu)美,讀起來瑯瑯上口,引導學生多讀,從而感受到語言文字背后的鮮明形象,引起學生對課文中描述的事物與情景的關注,入境入情,促進學生自悟自得。2.遵循以學生為主體、教師為主導、訓練為主線的三為主原則,引導學生在讀中積累、讀中感悟、讀中運用。架起閱讀教學與寫作教學之間的橋梁。
一、說教材《沙灘上的童話》是統(tǒng)編語文小學二年級下冊第四單元的一篇課文。這是一個非常感人的故事,課文比較具有童趣,與孩子的生活相貼近,符合孩子的年齡特點。 作者用詩一般的語言講述了一群孩子在沙灘上壘起一座城堡,然后展開想象的翅膀編織了一個美麗的童話:城堡里住著一個兇惡的魔王,搶走了美麗的公主……最后,這群孩子成為攻打城堡的勇士,他們炸死了魔王,救出了公主。故事一方面展現(xiàn)了孩子們快樂繽紛的童年生活,另一方面也歌頌了一種人間的善良溫情與正義。在孩子們的童話中,那對生活的熱愛之情,那純真地對他人的關愛和幫助,盡顯人性之美。二、說學情二年級下學期,學生已經(jīng)具備了一定的學習字詞的能力和自主閱讀的能力。這篇課文的詞語比較淺顯,可以讓學生在閱讀中自己積累。對于生字的教學,我重點講述容易混淆的生字,同時,這樣也可以從現(xiàn)在開始培養(yǎng)學生養(yǎng)成良好的預習及閱讀習慣。 但學生由于年齡小,注意力不夠集中,所以更喜歡情節(jié)性較強的故事,需要教師引導在故事中體驗情感。
六、說教學過程(一)創(chuàng)設情境,激趣導入 一堂課的開始,為了使學生盡快地進入學習狀態(tài),在情境創(chuàng)設中,應該做到新穎,要讓學生感受到一種新的情境,從而產生好奇心,達到集中注意力的目的。教學開始,我首先創(chuàng)設情境,提出了兩個問題:1.如果你在大街上迷路了,你會怎么做?2.如果你在野外迷了路,你又會怎么做?【設計意圖】這兩個問題的提出讓學生區(qū)分在不同的地點迷了路要用不同的方法。然后我順勢導入課文:我們來學習課文,看看如果在野外迷了路,有什么辦法分辨方向。(二)初讀課文,整體感知 1.讓學生自由讀課文,要求把字音讀準,把句子讀通順。然后老師范讀一遍,讓學生注意聽老師是怎么讀的,如字音、節(jié)奏等。2.再次自由讀課文,按著老師的方法讀詩歌,然后把本課的生字讀一遍?!驹O計意圖】這樣,學生對于課文的生字和大概內容就有了一個整體印象,培養(yǎng)了他們的自學能力。
一、說教材《中國美食》是統(tǒng)編語文小學二年級下冊第三組識字單元第四篇課文。課主要通過各種各樣的美食圖片,讓學生了解中國美食,通過認識這些美食從而學習生字。通過認識這些色香味俱全的美食,認識中國的美食化,增強民族自豪感,培養(yǎng)學生熱愛家鄉(xiāng)、熱愛祖國的感情。 本單元為識字單元,重在培養(yǎng)學生的識字興趣與能力。依據(jù)單元特點及新課標要求,低年級學生能借助漢語拼音認讀漢字,喜歡學習漢字,有主動識字的愿望,學會用普通話正確、流利地朗讀課問。二、說學情二年級學生已經(jīng)有了一定的知識基礎,并掌握了不少的識字方法,因此生字學習障礙相對而言較少。但他們的生活經(jīng)驗畢竟有限,對文中圖片中的菜品名稱不是全都了解,菜肴也不全都吃過。教學時要求學生認知菜肴名稱,了解菜肴,通過學習增強學生對中國美食的喜愛,對祖國的熱愛之情。
