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 themes of this part are “Talk about how to become an astronaut” and “Talk about life in space”. As Neil Armstrong said “Mystery creates wonder and wonder is the basis of man’s desire to understand. Space is difficult for human to reach, therefore, humans are full of wonders about it. However, if wanting to achieve the dream of reaching the Moon, some of our human should work hard to be an astronaut at first. Part A(Talk about how to become an astronaut) is a radio interview in a radio studio, where the host asked the Chinese astronauts about his story how to become an astronaut. Yang Liwei told his dreamed to be an astronaut since childhood. Then he worked hard to get into college at 22. The next 10 years, he gradually became an experienced pilot. At the same time, to be an astronaut, he had to study hard English, science and astronomy and trained hard to keep in good physical and mental health and to practise using space equipment. Part B (Talk about life in space) is also an interview with the astronaut Brown, who is back on the earth. The host Max asked about his space life, such as his emotion about going back the earth, the eating, shower, brushing, hobbies and his work. Part A and Part B are interviews. So expressing curiosity about the guests’ past life is a communicative skill, which students should be guided to learn.1. Students can get detailed information about how Yang Liwei became an astronaut and Max’s space life.2. Students learn to proper listening strategy to get detailed information---listening for numbers and taking notes.3. Students can learn related sentences or phrases to express their curiosity like “ I wish to know...” “I’d love to know...”4. Students can learn more about the space and astronauts, even be interested in working hard to be an astronaut
The theme of this unit focuses on “space exploration.” Students will learn about the training and experience needed to become an astronaut. The text is mainly about the development of space exploration. On the one hand, the text helps students to have a good understanding about the great feats humans have achieved, on the other hand, they will further understand the contributions that we Chinese have achieved, and feel confident and proud about our homeland and strengthen their love for our country. The teacher should instruct students to aim high and study harder to make great progress in the space career if possible.1. Read about the development and value of space exploration.2. Explore the mysteries of the universe and the achievements in space exploration.3. Skillfully use the vocabulary of this text to cultivate self-study ability 4. Develop cooperative learning ability through discussion.1. Enable the Ss to talk about the development and value of space exploration.2. Guide the Ss to summarize the main idea of each paragraph as well as the main idea of the text.3. Help Ss comprehend the main reasons for space exploration. Multi-media, textbook, notebooks.Step 1: Warming up and predictionLook at the title and the pictures of the text and predict what the text will be about?2. What are the main reasons for space exploration?
⑦在我看來(lái), 探索太空是值得的。As far as I am concerned, it is worthwhile to explore the space.Step 10 Writing---draftRecently, students in our class have had heated a discussion on whether space is worth exploring. Students hold different ideas about it.30% of us think space exploration is not worthwhile. They think space is too far away from us and our daily life and is a waste of money. And the money spent on space exploration can be used to solve the earth’s problems such as starvation and pollution.On the other hand,70% think space is worth exploring because we have benefited a lot from it,such as using satellites for communication and weather forecast. What’s more,with further space research,we may solve the population problem by moving to other planets one day. Also,space research will enable us to find new sources to solve the problem of energy shortages on the earth.As far as I am concerned, it is worthwhile to explore the space. Not only can it promote the development of society but also enrich our life. Step 11 Pair workExchange drafts with a partner.

Everybody wants to get wealth.In today’s material world,making money or becoming wealthy symbolizes a person’s success and capability. Many people just make every effort, pay any price to attain greater wealth. With money,they can buy nice, large apartments in nice neighborhood. With money they can own luxurious cars. Wealth seems to bring all happiness in life.But is wealth the only road to happiness? Not really. There are many things in the world, which are beyond the means of money, such as friendship, love, health and knowledge. People are so preoccupied with struggling for money that they have no time or would not take the time to form or maintain friendship. What happiness can they feel living as lonely miserable creatures without love or friends in the world even if they accumulate tremendous wealth?In my opinion, people can’t do anything without money, but money is not everything. What money will bring you depends on your personal belief and goal in life. If you are kind enough to help others, especially the poor, money is a good thing to you. With it, you can do much more for the benefit of people and your country, and it will add to your own happiness. If you want money just for your own needs, you’ll never be satisfied or happy. In a word,you should have money spent for more people. Only then can money be the source of your happiness.Step 8 Homework4 students in a group, one acts Roderick, one Oliver, one servant and the fourth one acts Henry Adams, then listen to the tape, pay more attention to the difference between American English and British English in pronunciation, stress, tone.

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.

2.講授新課:(約35分鐘)結(jié)合教材內(nèi)容重難點(diǎn)和學(xué)生實(shí)際,在講課過(guò)程中,我對(duì)教材內(nèi)容的順序進(jìn)行了重組,把教材內(nèi)容由原來(lái)的兩大部分劃分為三大部分(第一,價(jià)值判斷和價(jià)值選擇的含義和關(guān)系;第二,價(jià)值判斷和價(jià)值選擇的特征;第三,做出正確的價(jià)值判斷和價(jià)值選擇的標(biāo)準(zhǔn))。這一調(diào)整更符合學(xué)生的認(rèn)知結(jié)構(gòu),便于從整體上把握課本內(nèi)容。在講授過(guò)程中,我充分利用課本素材——探究活動(dòng)為課堂教學(xué)服務(wù),此外,利用學(xué)生的生活與體驗(yàn),挖掘?qū)嵗?,如結(jié)婚要禮由以前的舊三件到現(xiàn)如今的轉(zhuǎn)變,引導(dǎo)學(xué)生理解價(jià)值判斷和價(jià)值選擇的社會(huì)歷史性特征,以以《觀祈雨》、以醫(yī)生、藝術(shù)家、老學(xué)究對(duì)于《斷臂的維納斯》這個(gè)雕塑的不同見解、以新鮮實(shí)例韓國(guó)沉船事件和范跑跑為例啟發(fā)學(xué)生價(jià)值判斷和價(jià)值選擇具有主體差異性特征以此突破難點(diǎn),最后通過(guò)設(shè)疑、對(duì)比、追問(wèn)正確的價(jià)值判斷和價(jià)值選擇的標(biāo)準(zhǔn)來(lái)深化主題,突出重點(diǎn)。3.課堂小結(jié):(約2分鐘)強(qiáng)化認(rèn)識(shí)
(7)精講即精講點(diǎn)撥,釋疑解難?,F(xiàn)代教育理論一方面強(qiáng)調(diào)學(xué)生學(xué)習(xí)的主動(dòng)性;另一方面也重視發(fā)揮教師的積極性。課堂活動(dòng)的主動(dòng)性、合理性、有效性的實(shí)現(xiàn)還有賴于教師的講。精講就要求教師的講授內(nèi)容精要,分析精辟,語(yǔ)言精彩、節(jié)奏精練、點(diǎn)撥精當(dāng)。從內(nèi)容上看,本節(jié)課精講主要有三處:一、運(yùn)動(dòng)的含義;二、運(yùn)動(dòng)是物質(zhì)的根本屬性;三、靜止是運(yùn)動(dòng)的特殊狀態(tài)。2、教學(xué)手段多媒體輔助教學(xué)。六、教學(xué)過(guò)程第一步:創(chuàng)設(shè)情景,用“謎語(yǔ)”導(dǎo)入新課。使學(xué)生置身于教學(xué)內(nèi)容的情景之中,產(chǎn)生繼續(xù)探究的強(qiáng)烈愿望。第二步:運(yùn)用直觀、形象的畫面將教學(xué)目標(biāo)問(wèn)題,喚起學(xué)生參與欲望,驅(qū)使學(xué)生去思考,去自讀。第三步:引導(dǎo)學(xué)生相互討論,實(shí)現(xiàn)學(xué)生之間的橫向交流。第四步:教師依據(jù)反饋信息,給予重點(diǎn)講授、提示點(diǎn)撥、搭橋鋪路。第五步:設(shè)置故事型的模擬法庭,開展討論,在高潮中結(jié)束新課。第六步:總結(jié)概括,深化知識(shí),形成網(wǎng)絡(luò)。
