The topic of this part is “Discover the reasons for festivals and celebrations.The Listening & Speaking & Talking part aims at talking about the experiences and feelings or emotions about the festivals and celebrations. This section aims at detecting the reason why the people celebrate the festivals, the time, the places, the types and the way of celebrations. It also explains why some traditions in the old celebrations are disappearing, like the firecrackers in the big cities and some new things are appearing like the prosperity of business or commerce. 1. Students can talk about what festivals they know and the reasons and the way of celebrating them.2. Students should learn the reading skills such as the headline and get the topic sentences, the structures of articles.3. Students can understand the past, the present situation of some festival around the world and why there are some changes about them. 4. Students can have the international awareness about the festivals.1. Students should learn the reading skills such as the headline and get the topic sentences, the structures of articles.2. Students can understand the past, the present situation of some festival around the world and why there are some changes about them.Step 1 Lead in---Small talkWhat festival do you like best ? Why ?I like the Spring Festivals because I can set off the fireworks, receive the lucky money and enjoy the Gala with my families.Step 2 Before reading---Pair workWhy do people celebrate different festivals ?The Spring Festivals is to celebrate the end of winter and the coming of spring and new life.The Mid-autumn Day is to celebrate the harvest and admire the moon.
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.
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. Read quickly to get main idea; read carefully to get the detailed information about Naadam Festival.2. Learn the structure of the reading article and language.3. Write an article about a festival experience4. Learn to use the psychology, emotions and feeling in the writing.1. Write an article about a festival experience.2. Use the structure of the reading article and language.

四、教學(xué)過程1.導(dǎo)入新課(2分鐘)出示中非合作論壇暨第3屆部長(zhǎng)級(jí)會(huì)議圖片。用時(shí)事引起學(xué)生注意,設(shè)問,“55年前,亞洲與非洲有哪一次跨越印度洋的握手”,提示答案“萬隆亞非會(huì)議”,給出答案導(dǎo)入新課2.外交環(huán)境:學(xué)生閱讀,教師分析。(3分鐘)3.外交方針之一:獨(dú)立自主的和平外交方針(5分鐘) 出示材料:《共同綱領(lǐng)》引文。學(xué)生、閱讀、提煉除新中國(guó)奉行獨(dú)立自主的外交政策。進(jìn)而由學(xué)生分析另起爐灶、打掃干凈屋子再請(qǐng)客和一邊倒。培養(yǎng)學(xué)生分析材料、利用材料的能力過度:新中國(guó)作出一邊倒大的積極主動(dòng)態(tài)勢(shì),社會(huì)主義陣營(yíng)的兄弟們也立刻作出了積極回應(yīng)。1949年10月2日,中蘇建立了外交關(guān)系。4.外交建樹之一:同蘇聯(lián)等17個(gè)國(guó)家建立外交關(guān)系(3分鐘)出示毛澤東訪問蘇聯(lián)等圖片和第一批建交的17個(gè)國(guó)家名字
問題設(shè)計(jì):通過這一課的學(xué)習(xí),同學(xué)們能解釋君主專制中央集權(quán)制度的含義嗎?【總結(jié)】封建專制主義中央集權(quán)制度包括專制主義和中央集權(quán)制兩個(gè)概念。專制主義是就中央的決策方式而言的,主要體現(xiàn)在皇位終身制和世襲制上,特征是皇帝個(gè)人獨(dú)裁專斷,集國(guó)家最高權(quán)力于一身,從決策到行使軍政財(cái)權(quán)都具有獨(dú)斷性和隨意性;中央集權(quán)則是相對(duì)于地方分權(quán)而言,其特點(diǎn)是地方政府在政治、經(jīng)濟(jì)、軍事等方面沒有獨(dú)立性,必須充分執(zhí)行中央的政令,一切服從于中央。三、秦朝中央集權(quán)制的影響展示圖片:《秦朝疆域圖》正是由于有一個(gè)統(tǒng)一集中的中央政權(quán),秦王朝才能積極開拓疆域,北拒匈奴,南吞百越,有利于我國(guó)多民族國(guó)家統(tǒng)一發(fā)展。為了鞏固統(tǒng)一的國(guó)家,秦朝還通過實(shí)行哪些措施鞏固統(tǒng)一局面?展示圖片:“秦半兩錢”“秦權(quán)”“小篆”“秦簡(jiǎn)”等圖片。正是有一個(gè)強(qiáng)有力中央政府,才統(tǒng)一了貨幣、文字、度量衡,才開驛道、修靈渠,從而促進(jìn)了中國(guó)經(jīng)濟(jì)文化的發(fā)展進(jìn)步。展示“孟姜女哭長(zhǎng)城”的故事材料從故事及你所掌握的材料中,你認(rèn)為秦朝能否長(zhǎng)治久安?為什么?
首先引導(dǎo)回顧細(xì)胞質(zhì)內(nèi)各個(gè)細(xì)胞器的分工協(xié)作、產(chǎn)生分泌蛋白的過程;同時(shí)思考:為什么這些細(xì)胞器可以這樣有條不紊的密切協(xié)作?這中間有沒有專門起協(xié)調(diào)和控制作用的部門?從而導(dǎo)入本節(jié)內(nèi)容。通過學(xué)生小組討論及師生共同分析“資料分析”中的4個(gè)實(shí)驗(yàn),總結(jié)出細(xì)胞核的功能,即細(xì)胞核是遺傳信息庫(kù),控制細(xì)胞代謝和遺傳的功能。在此基礎(chǔ)上,向?qū)W生舉出克隆羊多莉的實(shí)例,加強(qiáng)理解。設(shè)問:那么細(xì)胞核為什么能成為細(xì)胞代謝和遺傳的控制中心?要弄清這個(gè)問題,我們必須從細(xì)胞核的結(jié)構(gòu)中尋找答案,從而引出細(xì)胞的結(jié)構(gòu)。在這部分,引導(dǎo)學(xué)生思考以下幾個(gè)問題:(1)細(xì)胞核能控制細(xì)胞的遺傳,說明其應(yīng)該有什么物質(zhì)?(2)含有DNA的結(jié)構(gòu)如線粒體、葉綠體,它們的外面都有什么相同的結(jié)構(gòu)?(3)細(xì)胞核能控制細(xì)胞,肯定能與外界聯(lián)系,如何能辦到?(4)學(xué)習(xí)RNA的分布時(shí),RNA主要分布在細(xì)胞質(zhì),少量還分布在哪里呢?
四.設(shè)計(jì)反思我在設(shè)計(jì)本課時(shí),希望通過情境的創(chuàng)設(shè)充分再現(xiàn)歷史,并利用多媒體輔助教學(xué),破重點(diǎn)、化難點(diǎn),讓學(xué)生主動(dòng)參與到學(xué)習(xí)過程中,從而突破狹小的教室空間,讓學(xué)生真正做到感知?dú)v史,立足現(xiàn)實(shí),展望未來。自主,交流、合作、探究是課程改革中著力倡導(dǎo)的新型學(xué)習(xí)方式。課堂教學(xué)中如何開展小組合作的探究學(xué)習(xí)存在著很多困難,首先是課堂教學(xué)時(shí)間有限,如何體現(xiàn)面向全體,給每個(gè)學(xué)生以機(jī)會(huì)?再次,歷史問題的討論只能依托于史料才能使討論不淪為空談,課堂上通過網(wǎng)絡(luò)提供大量的史料(文字、圖片或其他),勢(shì)必不能有充分時(shí)間讓學(xué)生閱讀分析。如何解決這些問題呢?措施一:要形成較固定的歷史學(xué)習(xí)合作小組。選定一位同學(xué)擔(dān)任組長(zhǎng),負(fù)責(zé)協(xié)調(diào)措施二:要設(shè)置有利于學(xué)生探究的問題情境措施三:要把課堂教學(xué)與課外學(xué)習(xí)結(jié)合起來。在課前就印發(fā)相關(guān)的材料,或引導(dǎo)學(xué)生去查閱相關(guān)的資料,讓學(xué)生有個(gè)充分的閱讀、思考、交流的時(shí)間,是保證課堂上小組交流能成功實(shí)現(xiàn)的一個(gè)前提
