一、知識和技能1.使學(xué)生能夠正確認(rèn)識太陽的基本特征及其外部結(jié)構(gòu);2.了解太陽能量的來源,理解太陽是地球的主要能量源;3.了解太陽活動(主要是黑子和耀斑)對地球的影響。二、過程和方法1.能通過展示的圖片理解太陽活動增強(qiáng)時(shí)會使地球無線電短波通訊受干擾及產(chǎn)生磁暴現(xiàn)象的原因。2.通過對各種資料的觀察以及課前室外的觀測,培養(yǎng)學(xué)生獲取地理信息的能力和分析、判斷、推理等邏輯思維能力三、情感、態(tài)度、價(jià)值觀培養(yǎng)學(xué)生樹立正確的人地觀、科學(xué)的宇宙觀,和熱愛科學(xué)勇于探索的精神【教學(xué)重點(diǎn)】1.知道太陽輻射對地球的影響; 2.知道太陽活動對地球的影響;3.太陽的外部結(jié)構(gòu)和能量來源【教學(xué)難點(diǎn)】太陽活動(黑子和耀斑)對地球的影響
1.生產(chǎn)功能:合成有機(jī)物的能力2.平衡功能:使自然地理要素的性質(zhì)保持穩(wěn)定的能力【教師講解】生產(chǎn)功能主要依賴于光合作用。在光合作用過程中,植物提供葉綠素,大氣提供熱量和二氧化碳,土壤及水圈、巖石圈提供水分及無機(jī)鹽。光合作用通過物質(zhì)和能量的交換,將生物、大氣、水、土壤、巖石等地理要素統(tǒng)一在一起,在一定的條件下,生產(chǎn)出有機(jī)物。由此可見,生產(chǎn)功能是自然環(huán)境的整體功能而非單個(gè)地理要素的功能。大氣本身不具有減緩二氧化碳增加的功能,但是,在自然地理環(huán)境中,通過各地理要素的相互作用,卻能消除部分新增的二氧化碳的能力,既為自然地理環(huán)境的平衡功能。請大家閱讀教材P94活動,利用平衡功能的原理,解釋一定范圍內(nèi)各物種的數(shù)量基本恒定這一現(xiàn)象?!緦W(xué)生討論回答】略。(可參考教參)【轉(zhuǎn)折】自然地理環(huán)境各要素每時(shí)每刻都在演化,如我們熟知的氣候變化、地貌變化等。各個(gè)要素的發(fā)展演化是統(tǒng)一的,一個(gè)要素的演化伴隨著其他各個(gè)要素的演化。
(1)下面列出的是我國南北方傳統(tǒng)民居的差異,分析形成這些差異的自然原因:——北方民居正南正北的方位觀比南方強(qiáng);——北方民居的墻體嚴(yán)實(shí)厚重,南方民居的墻體輕?。弧獜谋钡侥?,民居的屋頂坡度逐漸增大,房檐逐漸加寬,房屋進(jìn)深和高度逐漸加大。(2)下面列出的是我國南北方城市住宅摟的差異,分析導(dǎo)致這些差異的自然原因:——如果不考慮地價(jià)、建筑材料等因素,建同等面積的住房,北方的建筑成本比南方高 ;——建同樣高度的多幢樓房,北方樓房的南北間距比南方大。點(diǎn)撥:本活動要求學(xué)生了解由于地理環(huán)境的差異造成南北方建筑物特點(diǎn)的不同,并由此認(rèn)識地理環(huán)境 差異對人們生活的影響。(1)比較而言,北方的冬季寒冷而漫長,南方的夏季濕熱而漫長。為了在冬季充分利用太陽光照和熱量,北方民居正南正北的方位觀比南方強(qiáng)。北方民居的墻體嚴(yán)實(shí)厚重,利用在冬季保溫御寒;南方民居的墻體輕薄,利于在夏季通風(fēng)透氣。從北到南,年降水量逐漸增大,民居的屋頂坡度也逐漸增大(利于排水) ;隨著對保溫要求的降低和對通風(fēng)納涼要求的提高,民居的屋檐逐漸加寬,房屋進(jìn)深和高度逐漸加大。
活動建議:亞馬孫雨林的開發(fā)和保護(hù),一直作為一個(gè)兩難問題困擾著決策者們。這三個(gè)議題的提出,為決策者們提供了思考的途徑,其實(shí)這也是國際社會的呼聲。活動中,可以讓同學(xué)們?nèi)我膺x一個(gè)感興趣的議題,進(jìn)行評述、整理、發(fā)揮,然后進(jìn)行交流,達(dá)成共識?;蛞园鍒?bào)的形式 進(jìn)行。板書設(shè)計(jì)第二節(jié) 森林的開發(fā)和保護(hù)——以亞馬孫熱帶雨林為例四、亞馬孫開發(fā)計(jì)劃及其影響1.全球熱帶雨林被毀的原因⑴直接原因——人類的開發(fā)⑵亞馬孫地區(qū),破壞雨林的人類活動:⑶開發(fā)的背景:2.亞馬孫地區(qū)開發(fā)過程⑴從歷史因素看,對雨林影響不大。⑵20世紀(jì)五六十年代后,影響逐漸加大3.亞馬孫流域 大規(guī)模開發(fā)計(jì)劃⑴修建亞馬孫橫貫公路 ⑵移民亞馬孫平原⑶借助外資、鼓勵(lì)跨國企業(yè)投資開發(fā)五、雨林的前途——開發(fā)還是保護(hù)1.目前,全球的熱帶雨林正以驚人的速度不斷減少。2.亞馬孫這片全球最大的熱帶雨林,前景也同樣不容樂觀。3.開發(fā) 與保護(hù)?
1.閱讀圖5.16,說明產(chǎn)業(yè)向國外轉(zhuǎn)移對日本經(jīng)濟(jì)的不利影響。點(diǎn)撥:圖5.16直觀的顯示了產(chǎn)業(yè)轉(zhuǎn)移對日本經(jīng)濟(jì)的不利影響:形成“產(chǎn)業(yè)轉(zhuǎn)移出去的多,轉(zhuǎn)移進(jìn)來的少→國內(nèi)生產(chǎn)投資不足,生產(chǎn)困難→市場萎縮→產(chǎn)業(yè)向外轉(zhuǎn)移,外資不愿進(jìn)入”的惡性循環(huán)。2.盡管重化工業(yè)的環(huán)境污染比較嚴(yán)重,但是卻能為工業(yè)化的發(fā)展提供堅(jiān)實(shí)的基礎(chǔ),因此成為發(fā)達(dá)工業(yè)的象征。日本、韓國的經(jīng)濟(jì)發(fā)展都經(jīng)歷了由輕工業(yè)(勞動密集型)到重化工業(yè)(資源密集型和資金密集型)到高科技工業(yè)(技術(shù)密集型)的階段。(1)為什么日本、韓國在重點(diǎn)發(fā)展重化工業(yè)之前,要先發(fā)展勞動密集型工業(yè)?點(diǎn)撥:重化工業(yè)的發(fā)展一方面需要有一定的工業(yè)基礎(chǔ)和技術(shù)工人,另一方面需要投入大量的資金,先發(fā)展勞動密集型工業(yè)有利于利用勞動力資源豐富且廉價(jià)的優(yōu)勢,積累資金和造就產(chǎn)業(yè)工人。所以,勞動力豐富的發(fā)展中國家或地區(qū)的工業(yè)化往往從優(yōu)先發(fā)展勞動密集型工業(yè)開始。
2.通過西氣東輸輸送到上海的天然氣,價(jià)格只相當(dāng)于進(jìn)口天然氣的3/4、同等熱值煤氣的 2/3。你認(rèn)為是否應(yīng)該提高天然氣的價(jià)格,以促進(jìn)西部的發(fā)展。點(diǎn)撥:可以從不同方面分析。⑷對環(huán)境的影響①有利于改善東部地區(qū)的大氣質(zhì)量據(jù)監(jiān)測顯示,在同等熱值的情況下,與煤炭相比,利用天然氣作燃料幾乎不產(chǎn)生二氧化硫、粉塵等污染物質(zhì),氮氧化物和二氧化碳的排放量也大為減少。長江三角洲地區(qū)的能源長期高度依賴煤炭,例如,上海市煤炭消費(fèi)量占能源消費(fèi)總量的70%。從西部地區(qū)輸送來的天然氣,可以部分替代煤炭。②為了最大限度減少對沿線地區(qū)生態(tài)環(huán)境的影響,西氣東輸工程在建設(shè)過程中,嚴(yán)格環(huán)境保護(hù)的要求。③在沿線農(nóng)村地區(qū)推廣使用天然氣,可減少農(nóng)民對薪柴的需求,從而緩解因植被破壞而帶來的環(huán)境壓力。

Textbook: Senior English for China (Book 4), by Liu Daoyi Time Allotment: 1 period (40 minutes)Date: March 20, 2014Teaching aids: blackboard, Multi-media, Power Point, chalk I. Text Analysis (教材分析)This unit is about body language, and the text selected in the reading part demonstrates the difference and similarity of body language in many parts of the world. Through learning this passage, students are required to raise their awareness of using body language in different parts of the world. As body language is closely related to our daily life, it is easy to arouse students’ interest in learning this text. Reading skills and speaking training are designed around the text.II. Teaching Objectives (教學(xué)目標(biāo))By the end of the lesson, students will be able to:1. Language Skill Objective(語言技能目標(biāo)): develop reading ability (skimming and scanning)as well as speaking ability.2. Cultural Knowledge Objective(文化知識目標(biāo)): know about the cultural differences of using body language.3. Affective Objective(情感目標(biāo)): increase students’ awareness of using body language correctly in different cultures. III.Teaching Focuses and Difficulties(教學(xué)重點(diǎn)和難點(diǎn))1. Teaching Focuses(教學(xué)重點(diǎn)): the difference and similarity of body language in many parts of the world.2. Teaching Difficulties(教學(xué)難點(diǎn)): develop students’ reading abilities of skimming and scanning and ask the students to show their opinions with fluent English.
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 morning, distinguished judges:It’s my honor to talk about my teaching ideas with you. Today my topic is Women of Achievement. My presentation consists of six parts: the analysis of teaching material and student, teaching aims, key and difficult points, teaching and studying method, teaching procedures and blackboard design.First, let’s focus on the analysis of teaching material. This lesson is from New Senior English for China Student’s Book 4 Unit 1, the reading part. The main topic of the passage is the introduction of a student of Africanwildlife. After this lesson, the students will learn more information about her studying chimps in Africa, and their reading and speaking abilities can be developed as well.The next part is the analysis of students. My students are in senior high students. They have learnt English for many years, they’ve known many words and sentences, but their speaking and reading abilities are still not very good. So I will practice their speaking and reading abilities through different exercises.According to the New Standard Curriculum and the present situation, I set the teaching aims as follows: firstly, knowledge aims. Students can grasp some new words, such as worthwhile, move off. Moreover, students can understand the content of the passage and get familiar with the topic of studying chimps in wildlife. Secondly, ability aims. Students can use reading strategies such as skimming and scanning in reading process. Thirdly, emotional aims. Students can have the awareness of protecting animals and care about animals.Based on the above analysis, the key point of this lesson is to get the main idea and the detailed information from the passage; the difficult point is to talk about the wildlife protection and use reading strategies.
在接下來的細(xì)讀環(huán)節(jié),我套用了高考對閱讀理解的考查方式設(shè)置了5個(gè)問題,分別為三個(gè)推理判斷題,一個(gè)細(xì)節(jié)題和一個(gè)主旨大意題。學(xué)生需要對文章的內(nèi)容進(jìn)行分析、歸納、推理、猜測等高級思維活動才能做出正確的回答?!驹O(shè)計(jì)意圖】這一過程是對學(xué)生進(jìn)行細(xì)讀的訓(xùn)練,培養(yǎng)學(xué)生獲取特定信息和挖掘文章深層次信息的能力。第三環(huán)節(jié):Intensive-reading (精讀) 15′第三個(gè)環(huán)節(jié)精讀,既是最重要的環(huán)節(jié),也是突破本課重難點(diǎn)的關(guān)鍵。首先,讓學(xué)生思考劇本中人物看到百萬英鎊前后的態(tài)度發(fā)生了怎樣的變化。其次,讓學(xué)生仔細(xì)閱讀文章,找出可以表現(xiàn)人物態(tài)度變化的具體的語言和動作。最后,讓學(xué)生總結(jié)人物的態(tài)度發(fā)生變化的根本原因是什么,從而引出Money Talks, 供學(xué)生思考?!驹O(shè)計(jì)意圖】通過一系列的活動培養(yǎng)學(xué)生學(xué)習(xí)從人物的語言和動作探究人物的心理,使學(xué)生進(jìn)一步體會戲劇語言的魅力,從而對文章背后所反映的社會問題進(jìn)行思考,也為下一步的討論環(huán)節(jié)做好鋪墊。

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(jì))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.
