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 4 Space Exploration-Listening&Speaking＆Talking教學(xué)設(shè)計二
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.

⑦在我看來, 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.

有的學(xué)者還指出，要堅(jiān)持集體主義還必須將集體主義的價值精神與社會主義市場經(jīng)濟(jì)的要求結(jié)合起來，批判地繼承計劃經(jīng)濟(jì)時代倡導(dǎo)的集體主義，合理地對其進(jìn)行體系結(jié)構(gòu)的調(diào)整和內(nèi)容的更新，形成新的集體主義。與傳統(tǒng)的集體主義相比，這種新的集體主義應(yīng)具有如下兩個主要特點(diǎn)。其一，強(qiáng)調(diào)集體的出發(fā)點(diǎn)是為了維護(hù)集體成員的正當(dāng)個人利益。傳統(tǒng)的集體主義具有片面強(qiáng)調(diào)集體至上性、絕對性的弊端；新的集體主義必須依據(jù)社會主義市場經(jīng)濟(jì)的現(xiàn)實(shí)要求，將集體應(yīng)當(dāng)對個人承擔(dān)的義務(wù)加以科學(xué)的闡釋。真正的集體應(yīng)該維護(hù)各個集體成員的個人利益，實(shí)現(xiàn)組成集體的各個主體的自我價值。這種新型的集體主義是對社會主義市場經(jīng)濟(jì)條件下社會關(guān)系的真實(shí)反映，既與個人主義有本質(zhì)區(qū)別，也不同于傳統(tǒng)的集體主義。其二，要體現(xiàn)道德要求的先進(jìn)性與廣泛性的統(tǒng)一。

1．促使美國成為一個移民國家的因素是：①美洲屬于未開發(fā)的新大陸，需要大量的勞動力；②歐洲失業(yè)工人和破產(chǎn)農(nóng)民增加，人們?yōu)榱俗非蟾玫慕?jīng)濟(jì)待遇遷往美洲；③新航線的開辟為人們順利遷移掃除了障礙；④殖民擴(kuò)張是人口遷移的促進(jìn)因素，加快了人口遷移的過程。導(dǎo)致美國人口在本土范圍內(nèi)頻繁遷移的原因，歸納起來有：第一次人口遷移是戰(zhàn)爭因素，第二次是城市化；第三次是自然環(huán)境、經(jīng)濟(jì)環(huán)境的變化；第四次是經(jīng)濟(jì)格局的變化，即西部和南部新資源的發(fā)現(xiàn)和新興工業(yè)的發(fā)展。2．我國古代的人口遷移，深受統(tǒng)治者及其行政力量的束縛。封建帝王為了加強(qiáng)本國的經(jīng)濟(jì)和軍事實(shí)力，對人口遷移嚴(yán)加控制。只有當(dāng)戰(zhàn)亂發(fā)生的時候，這種控制才得到削弱，人們?yōu)榱硕惚軕?zhàn)亂，尋找安定的生活環(huán)境，不得不進(jìn)行大規(guī)模的遷移。我國近幾十年的人口遷移主要是由生產(chǎn)資料和勞動力數(shù)量上的地區(qū)分布不平衡造成的，是經(jīng)濟(jì)因素在起主導(dǎo)作用，與古代的人口遷移截然不同。
