人教版高中語文必修1《奧斯維辛沒有什么新聞》教案2篇
3．作者為什么不直接描寫人們看見東西呢？請同學們找出其中的細節(jié)描寫，并說明有什么表達效果。答：側面烘托，正是作者高明之處，這也是許多佳作常用之法。細節(jié)描寫往往會成為事情的切入點和突破口，一篇佳作往往離不開一些細節(jié)描寫，本文也不例外，有些細節(jié)描寫耐人尋味，如：“德國人撤退時炸毀的布熱金卡毒氣室和焚尸爐廢墟上，雛菊花在怒放?！薄斑@是一個二十多歲的姑娘，長得豐滿，可愛，皮膚細白，金發(fā)碧眼。她在溫和地微笑著，似乎是為著一個美好而又隱秘的夢想而微笑?！?.句子賞析：“對另外一些人來說，這樣一個事實使他們終生難忘：在德國人撤退時炸毀的布熱金卡毒氣室和焚尸爐廢墟上，雛菊花在怒放?！泵鞔_：一邊是戕害生命的毒氣室和焚尸爐，一邊是生機勃勃的生命，兩種反差極大的事物擺在一起。表達了作者對納粹的諷刺：納粹的殘暴終歸阻止不了生命的進程。同時也表達了作者的控訴：生命的綻放是人世間最美好的事情，對生命的戕害是最惡劣的罪行。

新人教版高中英語必修3Unit 1 Festivals and Celebrations-Listening &Speaking＆Talking教學設計
The theme of this section is “Talk about festival activities and festival experiences”.Festival and holiday is a relaxing and interesting topic for students. This part talks about the topic from the daily life of students’. In the part A ---Listening and Speaking, there are three conversations among different speakers from three countries(Japan, Rio and China), where the speakers are participating in or going to participate in the festivals and celebrations. So listening for the relationship among them is a fundamental task. Actually, with the globalization and more international communication, it is normal for Chinese or foreigners to witness different festivals and celebrations in or out of China. In the Conversation 1, a foreign reporter is interviewing a Japanese young girl who just had participated in the ceremony of the Coming-of-Age Day on the street and asking her feeling about the ceremony and the afterwards activities. Conversation 2, Chinese girl Li Mei is witnessing the Rio Carnival for the first time, and her friend Carla gives her some advice on the costumes which enables her to match with the carnival to have a good time. Conversation 3, a Chinese guide is showing a group of foreign visitors around the Lantern Festival and introducing the customs of the festival to them. The three conversations have a strong vitality and insert the festival and cultural elements from different countries. So perceiving the festivals and cultures from different countries is the second task. At the same time, the scripts also insert the targeted grammar --- v-ing as attributive and predicative, which students can perceive and experience in a real context and make a road for the further study. That is the third task. In the Part B--- Listening and Talking, the theme is “Talk about festival experience”, which is the common topic in our daily conversations. During the conversation, Song Lin, a Chinese student, asked Canadian friend Max about how to spend Christmas. In the conversation, Song Lin talked about experience and the feelings during the Chinese Spring Festival, during which there are not only some enjoyable things but some unpleasant things. After the listening, perhaps students find there are some similarities between Christmas and the Chinese Spring Festival as there are some differences in the origins and celebrations. For example, people always visit friends and relatives, decorate their houses, have a big dinner together, chat and give presents to each other.
新人教版高中英語必修3Unit 1 Festivals and Celebrations-Reading for writing教學設計二
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.

The topic of this part is “Write about your festival experience”.During the Listening and Speaking and Talking, students are just asked to say out their festival experiences such as the Spring Festival, Mid-autumn Day, but this part students will be asked to write down their own festival experiences. During the reading part, it introduces the Naadam Festival in Inner Mongolia Autonomous Region, which can give students a good example to imitate. Students not only learn the festival, but touch and feel the Inner Mongolian’s character, the spirit and cultural atmosphere, which can help students form the cultural awareness and learn to enjoy and value the diversity of Chinese culture.Concretely, the dairy tells the experience that the author spent the Naadam Festival in Inner Mongolia Autonomous Region with his/her friend. The structure is clear. In the opening paragraph, it introduces the topic of the Naadam Festival and the whole feeling. Then it introduces the items of the festival like the ceremony, wrestling and horse racing. Finally, it summarizes this experience. Because this part is a travel journal, we must guide students pay more attention to these details: 1. use the first person. 2. use the past tense to tell the past thing and use the present or future tense to describe the scenery. 3. use the timeline to tell the development. 4. be careful for the author’s psychology, emotion and feeling, etc.1.

人教版高中地理必修1第二章第四節(jié)全球氣候變化教案
氣候變化對健康的影響 氣候變化對人體健康的不良影響是不難發(fā)現的：熱浪沖擊頻繁加重可致死亡率及某些疾病、特別是心臟呼吸系統(tǒng)疾病發(fā)病率增加；對氣候變化敏感的傳染性疾病如瘧疾和登革熱的傳播范圍可能增加。極端氣候事件, 如干旱、水災、暴風雨等, 使死亡率、傷殘率及傳染病疾病率上升, 并增加社會心理壓力。某些媒介疾病的加重也可能與氣候變化有間接的關系, 如瘧疾是通過蚊子傳播的疾病,氣候變化可能使某些變暖地區(qū)的蚊子數目增加, 從而加重了瘧疾的發(fā)生。我國1994年瘧疾的發(fā)病率為5.3408/10萬, 居全國法定傳染病的第六位。血吸蟲病的發(fā)展與高溫及灌溉系統(tǒng)的擴增有關。我國1994年南方12省市血吸蟲病患者的檢出率高達3.67%，不能忽視氣候變化對此的可能影響。還有一些疾病，如睡眠病、登革熱、黑熱病等也有與氣候關系的報道。另外, CO2、一些空氣污染物如氮氧化物、臭氧等可增加過敏疾患及心臟呼吸系統(tǒng)疾病和死亡。
人教版高中地理必修1第三章第一節(jié)自然界的水循環(huán)教案
淺層地下水是貯存于地表松散堆積物中的潛水。主要受降水、氣溫、蒸發(fā)等氣象因素影響，有明顯的季節(jié)變化與日變化，并與河水有相應補給關系，即河水高于潛水面時，河水補給地下水，反之地下水補給河流；深層地下水是長時間內滲入地下深入儲存起來的，它緩慢地流出補給河流，受氣象因素影響很小，通常只有年變化，季節(jié)變化已不明顯。當然，一條河流的河水補給來源往往不是單一的，而是以某一種形式為主的混合補給形式，對流域自然條件復雜的大的河流來說尤其如此。我國長江上游地區(qū)除雨水、地下水外，高原高山上冰川、積雪在夏季融化也補給河流；東北地區(qū)的河流，由春季融化積雪補給，夏季則由雨水和地下水補給；西北內陸盆地除雨水外，夏季高山冰川、積雪融化成為河流的主要補給形式。我國季風地區(qū)，大部分河流以雨水補給為主，而冬季則由地下水補給。
人教版高中地理必修1第四章第二節(jié)山岳的形成教案
一、明確課標要求1.了解褶皺的概念和褶皺的基本形態(tài)；2.了解褶皺山的形成和褶皺山的基本形態(tài)特征；3.能夠在不同的示意圖中識別和判讀背斜與向斜；4.知道和理解斷層的概念和斷塊山的形成，了解斷塊山的基本形態(tài)特征；5.知道火山的形成、結構和規(guī)模。二、教學目標知識目標：1.結合具體圖像，了解褶皺山的形成及基本形態(tài)特征。2.能在示意圖上識別和判斷背斜和向斜。3.理解內外力共同作用下形成的“背斜成谷，向斜成山”，并能夠明白其形成的原因。4.能夠結合實例，理解斷塊山的形成及基本特征。5.知道火山的形成、結構和規(guī)模。過程與方法目標：1.結合實例，分析造成地表形態(tài)變化的內力、外力因素。2.通過案例，嘗試聯系實際，培養(yǎng)動手演示、判讀圖像、比較、分析、歸納的能力。
人教版高中地理必修1第五章第二節(jié)自然地理環(huán)境的差異性教案
【補充說明】我們這節(jié)課簡要地分析了陸地環(huán)境的三種地域分異規(guī)律。實際上，世界上的任何事物有其一般性，也有它的特 殊性。在地帶性分異規(guī)律的基礎上，陸地環(huán)境因為受到海陸分布、地形 起伏等因素的影響，也會出現一些不規(guī)律的現象，這種現象稱為非地帶性。例如，我們在初中地理中學過綠洲。還記得什么叫綠洲嗎？再比如，在南美洲的西海岸（太平洋沿岸），有一條狹長的（熱帶）荒漠帶，而缺少熱帶草原帶，熱帶雨林帶主要是分布在赤道以北地區(qū)。這主要是受大的地形起伏的影響。因為南美洲西部是一列高大的安第斯山脈，受其影響，兩邊的氣候狀況不同，所以就出現了分布規(guī)律不同的自然帶，這也是一種非地帶性現象。【總結】有規(guī)律分布的自然帶構成了全球和諧的自然環(huán)境整體。自然帶之間錯綜復雜的、微妙的要素關系，有許多是人類還沒有認識到的。因此，人類不能隨意去破壞任何哪怕是極微小的環(huán)節(jié)，也許它 帶來的影響會是全球性的。保護全球環(huán)境，人人有責。

人教版高中地理必修1冷熱不均引起的大氣運動教案
討論：二氧化碳在大氣的受熱過程中起到了什么作用？（吸收太陽輻射中的紅外線輻射和地面輻射，保溫作用）大氣中的二氧化碳濃度增大對氣溫有什么影響？（全球氣候變暖）閱讀：我們知道了太陽輻射中的可見光和紅外 光能量的吸收和轉化，那么紫外區(qū)的能量到哪兒去了？請同學們查閱資料，自主探討。小結：大氣的受熱過 程就是太陽曬熱了地面，地面烘熱了大氣。太陽輻射是大氣的根本熱源，地面輻射是大氣的直接熱源。這就是為什么海拔越高，氣溫越低的原因，難怪高處不勝寒！轉承：大氣的直接熱源是地面，不同性質的地面溫度是不同的，同緯度，海洋和陸地就有溫差。提問：請學生說說白天和晚上在海邊的不同感受。由白天和晚上的風向不同切入實驗P32活動。討論：通過煙霧的飄動，我們得出了什么規(guī)律？冷熱不均引起了熱力環(huán)流板書： 二、熱力環(huán)流板圖與分析：結合試驗，學生分析熱力環(huán)流 的產生
人教版高中地理必修1第四章第一節(jié)營造地表形態(tài)的力量教案
晶晶和亮亮是兩滴巖漿，他們生活在地球內部的：巖漿之家。一天，他們得到批準，與其他同伴一起到地球表面進行旅行。他們飛快地奔向地表，半路上，晶晶覺得累了，于是就與亮亮約好，在地表匯合。亮亮沒有停步，與其他伙伴一起跳出地表，并沿著山坡往低處流動。忽然，亮亮發(fā)現自己不能再動了，不禁問旁邊的同伴這是怎么一回事。同伴笑著說：“別擔心，只不過你已經不再是巖漿罷了。”問題1、為什么同伴說亮亮已經不再是一滴巖漿了？2、你認為亮亮還可以繼續(xù)他的地表旅行嗎？請說明原因。（由學生討論回答。）過了好長的一段時間，亮亮發(fā)現自己的個頭變小了，并隨著風和流水往前運動了。亮亮邊走邊欣賞著地表美麗的風光。忽然，亮亮發(fā)現一個熟悉的身影，認真一看，原來是晶晶。亮亮驚訝地問：“你是怎么來到地表的？”3、請你簡要推測晶晶到達地表的過程。（由學生討論回答。）亮亮和晶晶又一起踏上旅程。
人教版高中地理必修1自然地理環(huán)境的整體性教案
1．生產功能：合成有機物的能力2．平衡功能：使自然地理要素的性質保持穩(wěn)定的能力【教師講解】生產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鹽。光合作用通過物質和能量的交換，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，生產出有機物。由此可見，生產功能是自然環(huán)境的整體功能而非單個地理要素的功能。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，解釋一定范圍內各物種的數量基本恒定這一現象?！緦W生討論回答】略。（可參考教參）【轉折】自然地理環(huán)境各要素每時每刻都在演化，如我們熟知的氣候變化、地貌變化等。各個要素的發(fā)展演化是統(tǒng)一的，一個要素的演化伴隨著其他各個要素的演化。
