1．懸念法懸念法又稱關(guān)子。它是作者為了激發(fā)那種“緊張與期待的心理活動(dòng)”，在行文中有意采取的一種積極而有效的手段。這種手段包括“設(shè)懸”和“解懸”兩方面。所謂 “設(shè)懸”就是設(shè)置懸念，即在情節(jié)發(fā)生發(fā)展的關(guān)鍵時(shí)刻或人物命運(yùn)攸關(guān)的重要關(guān)頭，敘述戛然而止，轉(zhuǎn)敘他事。從而引起讀者強(qiáng)烈的尋根問(wèn)底的興趣。所謂“解懸” 也叫“釋懸”，就是指在情節(jié)發(fā)展的特定階段，通過(guò)矛盾的解決，揭示事情原委和人物命運(yùn)的結(jié)局，使讀者的期待心理得以滿足。如《驛路梨花》，當(dāng)人們正為露宿而發(fā)愁時(shí)出現(xiàn)了一間神秘的小屋，小屋的主人是誰(shuí)呢？猜想間，有人來(lái)了，但也不是屋子主人，那小屋子的主人是誰(shuí)呢？終于知道了小屋是解放軍蓋的，但為什么要蓋這間小屋呢？這樣“設(shè)懸——釋懸——帶出新懸念”，環(huán)環(huán)相扣、層層遞進(jìn)，使文章韻味無(wú)窮。

天上有明月，年年照相思。她夜夜沉醉在夢(mèng)中。夢(mèng)把空間縮短了，夢(mèng)把時(shí)間凝固了，夢(mèng)把世界凈化了。夢(mèng)中沒(méi)有污穢，沒(méi)有嘈雜，沒(méi)有邪惡；夢(mèng)中沒(méi)有分離，沒(méi)有創(chuàng)傷，沒(méi)有痛苦；夢(mèng)中只有柔和的月色，只有溫馨的愛(ài)；夢(mèng)使她永遠(yuǎn)年輕，使她不原醒來(lái)?！。莻€(gè)世界，是為天下最真最善最美的心靈準(zhǔn)備的，藝術(shù)家懷著虔誠(chéng)的情感，用充滿魔力的琴弦，在人們的心中筑起了一座不朽的天堂，它像天地一樣長(zhǎng)久，日月一樣永恒！新月微微地閉著眼睛，她清清楚楚地看到了那座天堂，真真切切地觸到了那座天堂，冰凌砌成墻壁，白云鋪成房頂，霧靄織成紗幔，星星串成明燈；在那里，她的頭發(fā)像沐浴之后那樣清爽柔軟，隨風(fēng)飄拂，她的肌膚像披著月光那樣清涼潤(rùn)滑，她的那顆心啊，像浸潤(rùn)著蒙蒙細(xì)雨的花蕾，掛著晶瑩的露珠，自由地呼吸……她沉醉在那個(gè)一塵不染的美好的境界，如歌如詩(shī)，如夢(mèng)如幻，如云如月，如水如煙……

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.

人教版新課標(biāo)高中物理必修2宇宙航行教案2篇
動(dòng)畫展示三個(gè)宇宙速度（四） 讓學(xué)生具有振興中華的使命感與責(zé)任感本節(jié)課的最后，播放了一段美國(guó)登月的視頻，讓學(xué)生發(fā)現(xiàn)一些奇妙的物理現(xiàn)象，引導(dǎo)學(xué)生發(fā)現(xiàn)月球的背景是什么顏色，宇航員行走的模樣等等，預(yù)計(jì)不久的將來(lái)，哪個(gè)國(guó)家也將登上月球，同學(xué)們高呼“中國(guó)”，那么我們現(xiàn)在能做些什么呢，讓同學(xué)感想到：我們是祖國(guó)的未來(lái)的希望，現(xiàn)在需要努力學(xué)習(xí)科學(xué)文化知識(shí)，將來(lái)為祖國(guó)的航天事業(yè)做貢獻(xiàn)。要培養(yǎng)學(xué)生堅(jiān)韌不撥、勇于探索、協(xié)力合作的科學(xué)精神以及嚴(yán)謹(jǐn)求實(shí)、謙虛謹(jǐn)慎、勇于質(zhì)疑科學(xué)態(tài)度；也要培養(yǎng)學(xué)習(xí)者熱愛(ài)科學(xué)、熱愛(ài)祖國(guó)的情感；努力學(xué)習(xí)、振興中華的責(zé)任感。這些策略在本案例中得到了體現(xiàn)。（五）練習(xí)反饋，拓展延伸：［例題1］“2003年10月15日9時(shí)，我國(guó)神舟五號(hào)宇宙飛船在酒泉衛(wèi)星發(fā)射中心成功發(fā)射，把我國(guó)第一位航天員楊利偉送入太空。飛船繞地球飛行14圈后，于10月16日6時(shí)23分安全降落在內(nèi)蒙古主著陸場(chǎng)。”
人教版新課標(biāo)高中地理必修2第二章第三節(jié)城市化教案
[補(bǔ)充]：鄭州是特大城市，我們對(duì)燈火通明的夜晚都有深刻的體會(huì)，我們都體會(huì)過(guò)光給他們帶來(lái)的好處，而對(duì)過(guò)多過(guò)亮的光帶來(lái)的危害則很少認(rèn)真地思考過(guò)，且光污染給都市人們和其他生物和環(huán)境帶來(lái)的不利影響也越來(lái)越大，所以，我在這兒給同學(xué)們補(bǔ)充光污染，目的是提醒他們要增強(qiáng)環(huán)保意識(shí)，要理解城市在建設(shè)過(guò)程中要減少城市各類活動(dòng)對(duì)環(huán)境的污染；另外，隨著城市的不斷發(fā)展，還可能會(huì)產(chǎn)生新 的污染物。還培養(yǎng)了學(xué)生用發(fā)展的眼光來(lái)看世界。[思考]：如何降低城市化對(duì)地理環(huán)境產(chǎn)生的影響？[答]：發(fā)展生態(tài)城市，使人工環(huán)境和自然環(huán)境和諧統(tǒng)一起來(lái)。一方面在城市建設(shè)中，要發(fā)展低污染的節(jié)能建筑和綠色交通，減少城市各類活動(dòng)對(duì)環(huán)境的污染；另一方面使城市景觀盡可能地與山、河、湖、海、植被等自然景觀保持協(xié)調(diào)，建立一種良性循環(huán)。
