新人教版高中英語必修3Unit 1 Festivals and Celebrations-Listening &Speaking＆Talking教學設(shè)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.

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.

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(xiàn)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(zāi)、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(guān)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(shù)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(guān)。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(guān)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。

人教版高中語文必修3《善待生命 學習論證》教案2篇
論證方法之引證法如何用好引證法：1.所引用的名言警句等針對性要強。每句名言都產(chǎn)生于特定的背景，都應(yīng)用于特定的交際目的，即使談同一個問題，也有不少名言可供選取。2.要簡潔，不宜過多。議論是在發(fā)表自己的見解而不是在介紹他人的見解。引用他人的話，目的是為了讓讀者更加信服自己的話。3.要注意直接引用和間接引用的區(qū)別。直接引用務(wù)求文字、甚至標點均準確無誤；間接引用只須述其大意，但要注意人稱的轉(zhuǎn)換。論證方法之喻證法喻證法是用設(shè)喻來論證論點的方法。在議論文中，設(shè)喻可以使論點更易懂、更風趣、更容易獲得讀者的認同。喻證法能化抽象為具體、化艱深為淺顯、化枯燥為生動。論證方法之喻證法如何用好喻證法：1.以小見大，就近取譬。要精選生活中細小的、人們熟悉的事物做為設(shè)喻的喻體。2.喻體不求形似，只求神似。做為喻證的喻體與做為比喻的喻體不同。比喻的喻體是為了強調(diào)特征，描繪事物，側(cè)重形似，以形比形；而喻證的喻體是為了闡發(fā)觀點，以正視聽，力求神似，以義取形。

生：環(huán)境承載力是指環(huán)境能持續(xù)供養(yǎng)的人口數(shù)量。師：對了。但是有同學仍然會感到這是一個很抽象的概念。下面我們具體來了解什么是環(huán)境承載力。我們可以從兩個部分去理解：一、環(huán)境，它主要是指環(huán)境的單個要素（如：土地、水、氣候、植被等。）及其組合方式。二、是承載力，它指在特定的條件下，具體某事物能承受的某種活動的最大值。那環(huán)境承載力的科學定義是怎樣表達的呢？生：環(huán)境承載力是指某一時期，某種狀態(tài)條件下，某地區(qū)環(huán)境所能承受的人類活動作用的閾值。師：很對。 我們可以用一個生動的例子來說明。一只木桶里面的水的多少在底面積固定不變的情況下是由哪塊木板來決定？生：最短的那塊。師：確實如此。這就是我們平常所講的 “木桶效應(yīng)”。那影響環(huán)境承載力的大小也是由環(huán)境個要素里面最緊缺的那個要素來決定的。下面我們用一個例子來印證一下。
