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 1 Festivals and Celebrations-Listening &Speaking＆Talking教學(xué)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.

材料五航路開辟后，東方香料輸入歐洲的總量較中古之時猛增30倍，而胡椒、丁香等在印度購入和在英國賣出的差價亦高達10至29倍，其他貨物的獲利同樣驚人。這一時期，新的商品不斷涌現(xiàn)，特別值得注意的是美洲的特產(chǎn)——玉米、馬鈴薯、煙草、可可等——被傳播到歐亞大陸。這時，世界性的對外貿(mào)易主要通過大西洋，地中海與意大利皆告衰落，而沿大洋的英、荷等漸居中心。到17世紀時，英國的倫敦與荷蘭的阿姆斯特丹成為世界貿(mào)易中心。問題4：材料五表明，新航路開辟后對世界貿(mào)易產(chǎn)生了哪些重大影響？答案4：結(jié)束了世界相對孤立狀態(tài)；各地文明開始會合交流，日益連成一個整體；歐洲商人直接同世界各地建立商業(yè)聯(lián)系；促進不同國家和貿(mào)易的發(fā)展，促進世界市場雛形開始出現(xiàn)。

【教學(xué)參考】對“新政”作用的評價史學(xué)界對“新政”作用的評價是仁者見仁、智者見智，但基本上有三種觀點，即“功大于過論”、“過大于功論”和“功過參半論”。持“功大于過論”者認為“新政”在美國歷史上基本上是一種進步現(xiàn)象，首先，“新政”挽救了危機，使美國人民擺脫了危機的困苦局面；其次，在缺少足夠的宏觀經(jīng)濟政策知識的時代，羅斯福所做的努力確實是開創(chuàng)性的；再次，羅斯?！靶抡遍_啟了美國以后歷屆政府實施國家干預(yù)政策的大門，成為緩解自由主義經(jīng)濟制度之弊病的一劑良方，并在實質(zhì)上加強了美國聯(lián)邦政府的權(quán)威；最后，在30年代資本主義世界經(jīng)濟危機的背景下，同日本、德國為轉(zhuǎn)嫁危機而發(fā)動戰(zhàn)爭的策略相比，“新政”無疑代表了一種進步、民主的解救危機方式。持“過大于功論”者認為“新政”未能使美國走出蕭條、步入繁榮。
人教版新課標高中物理必修2功率教案2篇
1．用CAI課件模擬汽車的啟動過程。師生共同討論：①如果作用在物體上的力為恒力，且物體以勻速運動，則力對物體做功的功率保持不變。此情況下，任意一段時間內(nèi)的平均功率與任一瞬時的瞬時功率都是相同的。②很多動力機器通常有一個額定功率，且通常使其在額定功率狀態(tài)工作（如汽車），根據(jù)P=FV可知：當(dāng)路面阻力較小時，牽引力也小，速度大，即汽車可以跑得快些；當(dāng)路面阻力較大，或爬坡時，需要比較大的牽引力，速度必須小。這就是爬坡時汽車換低速擋的道理。③如果動力機器在實際功率小于額定功率的條件下工作，例如汽車剛剛起動后的一段時間內(nèi)，速度逐漸增大過程中，牽引力仍可增大，即F和v可以同時增大，但是這一情況應(yīng)以二者乘積等于額定功率為限度，即當(dāng)實際功率大于額定功率以后，這種情況不可能實現(xiàn)。
人教版新課標高中物理必修2平拋運動教案2篇
（五）平拋運動規(guī)律的應(yīng)用例1：一架老式飛機在高出海面45m的高處，以80m/s的速度水平飛行，為了使飛機上投下的炸彈落在停在海面上的敵船，應(yīng)該在與轟炸目標的水平距離為多遠的地方投彈?不計空氣阻力。分析：對于這道題我們可以從以下幾個方面來考慮：(1)從水平飛行的飛機上投下的炸彈，做什么運動?為什么?(2)炸彈的這種運動可分解為哪兩個什么樣的分運動?3)要想使炸彈投到指定的目標處，你認為炸彈落地前在水平方向通過的距離與投彈時飛機離目標的水平距離之間有什么關(guān)系?拓展：1、式飛機在高出海面45m的高處，以80m/s的速度水平飛行，尾追一艘以15m/s逃逸的敵船，為了使飛機上投下的炸彈正好擊中敵船，應(yīng)該在與轟炸目標的水平距離為多遠的地方投彈?不計空氣阻力。2、在一次摩托車跨越壕溝的表演中，摩托車從壕溝的一側(cè)以速度v＝40m/s沿水平方向向另一側(cè)，壕溝兩側(cè)的高度及寬度如圖所示，摩托車可看做質(zhì)點，不計空氣阻力。（1）判斷摩托車能否跨越壕溝？請計算說明（2）若能跨過，求落地速度？
