人教版高中地理必修2南京的自行車是多了還是少了說課稿
在學(xué)生回答的基礎(chǔ)上進行歸納小結(jié)：發(fā)展城市公共交通? 明確道路分工? 合理規(guī)劃停車場? 減少出行距離? 錯開出行高峰? 加大城市道路建設(shè)? 進行科學(xué)合理的交通管理，重視智能交通系統(tǒng)的建設(shè)提問：這組同學(xué)在幻燈片中提到城市環(huán)境污染源主要有哪些？城市交通環(huán)境問題除了交通工具的尾氣排放帶來大氣污染外，還會給城市環(huán)境帶來什么問題？這組同學(xué)基本同意自行車多是加劇南京空氣污染的間接原因，你同意他們的觀點嗎？在學(xué)生回答的基礎(chǔ)上，教師進行歸納小結(jié)：自行車是一種綠色交通工具，既環(huán)保又經(jīng)濟。只有當(dāng)它在某些機動車和非機動車不分的地段，影響車輛行駛速度的時候，它才可能成為加劇空氣污染的間接原因。那么我們針對交通工具對環(huán)境造成的影響，除了這組同學(xué)提到的三點解決措施以外，我們還有什么要補充的解決方法嗎？

例7 用描述法表示拋物線y＝x2＋1上的點構(gòu)成的集合．【答案】見解析 【解析】 拋物線y＝x2＋1上的點構(gòu)成的集合可表示為：{(x，y)|y＝x2＋1}．變式1．[變條件，變設(shè)問]本題中點的集合若改為“{x|y＝x2＋1}”，則集合中的元素是什么？【答案】見解析 【解析】集合{x|y＝x2＋1}的代表元素是x，且x∈R，所以{x|y＝x2＋1}中的元素是全體實數(shù)．變式2．[變條件，變設(shè)問]本題中點的集合若改為“{y|y＝x2＋1}”，則集合中的元素是什么？【答案】見解析 【解析】集合{ y| y＝x2＋1}的代表元素是y，滿足條件y＝x2＋1的y的取值范圍是y≥1，所以{ y| y＝x2＋1}＝{ y| y≥1}，所以集合中的元素是大于等于1的全體實數(shù)．解題技巧（認識集合含義的2個步驟）一看代表元素，是數(shù)集還是點集，二看元素滿足什么條件即有什么公共特性。

Step 3 Analyzing article structureActivity 31. Teachers raise questions to guide students to analyze the chapter structure of this diary and think about how to describe the festival experience. (1)What should be included in the opening/body/closing paragraph(s)?(2)How did the writer arrange his/her ideas?(3)What kind of interesting details did the writer describe?(4)How did the writer describe his/her feelings/emotions during the event?2. Students read and compare the three sentence patterns in activity 2. Try to rewrite the first paragraph of the diary with these three sentence patterns. After that, students exchange corrections with their partners. Such as:●This was my first time spending three days experiencing the Naadam Festival in China’s Inner Mongolia Autonomous Region and it was an enjoyable and exciting experience. ●I'll never forget my experience at the Naadam Festival because it was my first time to watch the exciting Mongolian games of horse racing, wrestling, and archery so closely. ●I'll always remember my first experience at the Naadam Festival in China’s Inner Mongolia Autonomous Region because it was so amazing to spend three days witnessing a grand Mongolian ceremony. Step 4 Accumulation of statementsActivity 41. Ask the students to read the diary again. Look for sentences that express feelings and emotions, especially those with the -ing form and the past participle. Such as:● …h(huán)orse racing, wrestling, and archery, which are all so exciting to watch. ● some amazing performances● I was surprised to see…● I was a little worried about. . . ● feeling really tiredOther emotional statements:●I absolutely enjoyed the archery, too, but the horse races were my favourite part. ●I'm finally back home now, feeling really tired, but celebrating Naadam with my friend was totally worth it. ●He invited me back for the winter to stay in a traditional Mongolian tent and cat hot pot. I can’t wait!2. In addition to the use of the -ing form and the past participle, the teacher should guide the students in the appreciation of these statements, ask them to memorize them, and encourage them to use them reasonably in writing practice.
新人教版高中英語必修3Unit 4 Space Exploration-Listening&Speaking＆Talking教學(xué)設(shè)計二
The themes of this part are “Talk about how to become an astronaut” and “Talk about life in space”. As Neil Armstrong said “Mystery creates wonder and wonder is the basis of man’s desire to understand. Space is difficult for human to reach, therefore, humans are full of wonders about it. However, if wanting to achieve the dream of reaching the Moon, some of our human should work hard to be an astronaut at first. Part A(Talk about how to become an astronaut) is a radio interview in a radio studio, where the host asked the Chinese astronauts about his story how to become an astronaut. Yang Liwei told his dreamed to be an astronaut since childhood. Then he worked hard to get into college at 22. The next 10 years, he gradually became an experienced pilot. At the same time, to be an astronaut, he had to study hard English, science and astronomy and trained hard to keep in good physical and mental health and to practise using space equipment. Part B (Talk about life in space) is also an interview with the astronaut Brown, who is back on the earth. The host Max asked about his space life, such as his emotion about going back the earth, the eating, shower, brushing, hobbies and his work. Part A and Part B are interviews. So expressing curiosity about the guests’ past life is a communicative skill, which students should be guided to learn.1. Students can get detailed information about how Yang Liwei became an astronaut and Max’s space life.2. Students learn to proper listening strategy to get detailed information---listening for numbers and taking notes.3. Students can learn related sentences or phrases to express their curiosity like “ I wish to know...” “I’d love to know...”4. Students can learn more about the space and astronauts, even be interested in working hard to be an astronaut

The theme of this unit focuses on “space exploration.” Students will learn about the training and experience needed to become an astronaut. The text is mainly about the development of space exploration. On the one hand, the text helps students to have a good understanding about the great feats humans have achieved, on the other hand, they will further understand the contributions that we Chinese have achieved, and feel confident and proud about our homeland and strengthen their love for our country. The teacher should instruct students to aim high and study harder to make great progress in the space career if possible.1. Read about the development and value of space exploration.2. Explore the mysteries of the universe and the achievements in space exploration.3. Skillfully use the vocabulary of this text to cultivate self-study ability 4. Develop cooperative learning ability through discussion.1. Enable the Ss to talk about the development and value of space exploration.2. Guide the Ss to summarize the main idea of each paragraph as well as the main idea of the text.3. Help Ss comprehend the main reasons for space exploration.

⑦在我看來, 探索太空是值得的。As far as I am concerned, it is worthwhile to explore the space.Step 10 Writing---draftRecently, students in our class have had heated a discussion on whether space is worth exploring. Students hold different ideas about it.30% of us think space exploration is not worthwhile. They think space is too far away from us and our daily life and is a waste of money. And the money spent on space exploration can be used to solve the earth’s problems such as starvation and pollution.On the other hand，70% think space is worth exploring because we have benefited a lot from it，such as using satellites for communication and weather forecast. What’s more，with further space research，we may solve the population problem by moving to other planets one day. Also，space research will enable us to find new sources to solve the problem of energy shortages on the earth.As far as I am concerned, it is worthwhile to explore the space. Not only can it promote the development of society but also enrich our life. Step 11 Pair workExchange drafts with a partner.

（四）、活動交流，體驗科學(xué)通過資料分析討論以下三個問題：1、你知道愛滋病的傳播途徑嗎？2、如何預(yù)防愛滋??？3、我們應(yīng)如何對待愛滋病患者？面對艾滋病我們能做些什么？從而進入情感態(tài)度的教育。除此之外，我還設(shè)計一個開放性的作業(yè)“向全社會為關(guān)注艾滋病設(shè)計一個宣傳廣告”（形式不限，漫畫、板書、倡議書等），讓學(xué)生把愛心付諸于實際行動。在此基礎(chǔ)上引出“免疫學(xué)的應(yīng)用”從免疫預(yù)防、免疫治療、器官移植三個方面講述，讓學(xué)生充分體驗到知識和社會生活的緊密聯(lián)系，讓他們不在感到科學(xué)是那么的遙遠，而是可愛的有用的。通過交流，讓同學(xué)們體會到合作的魅力和重要性，進一步培養(yǎng)合作意識和合作能力。最后我設(shè)計一個資料搜集，讓同學(xué)們選一個感興趣的主題利用電腦在網(wǎng)上搜集有關(guān)資料。主題：1、你知道世界艾滋病日嗎？歷年的主題是什么？開展世界艾滋病運動有什么意義？
人教版高中地理必修2第三章第二節(jié)以種植業(yè)為主的農(nóng)業(yè)地域類型說課稿
本節(jié)課標(biāo)解讀：1.說明以種植業(yè)為主的農(nóng)業(yè)地域類型的形成條件及特點；2.說出商品谷物農(nóng)業(yè)的分布范圍，說明商品谷物農(nóng)業(yè)的形成條件及特點。內(nèi)容地位與作用：農(nóng)業(yè)是受自然環(huán)境影響最大的產(chǎn)業(yè)。農(nóng)業(yè)是發(fā)展歷史最悠久的產(chǎn)業(yè)，隨著社會的發(fā)展和進步，社會環(huán)境對農(nóng)業(yè)的影響越來越大。以季風(fēng)水田農(nóng)業(yè)為主的農(nóng)業(yè)地域類型，主要體現(xiàn)自然環(huán)境對農(nóng)業(yè)地域形成的影響；商品谷物農(nóng)業(yè)則體現(xiàn)了社會環(huán)境對農(nóng)業(yè)地域形成的影響。本節(jié)內(nèi)容包括兩部分內(nèi)容，一個是季風(fēng)水田農(nóng)業(yè)，主要分布在亞洲季風(fēng)區(qū)；一個是商品谷物農(nóng)業(yè)，主要分布在發(fā)達國家。教材文字內(nèi)容不多，配備了大量的地圖和景觀圖。因此，在教學(xué)過程中要充分組織學(xué)生查閱地圖，挖掘地理信息，培養(yǎng)分析能力。分析農(nóng)業(yè)區(qū)位因素時，必須從自然因素和社會經(jīng)濟因素兩個方面去分析，找出優(yōu)勢區(qū)位因素來。
