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

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.

◇探究提示:傳統(tǒng)文化對(duì)現(xiàn)實(shí)生活是財(cái)富還是包袱,要具體問(wèn)題具體分析,不可一概而論。例如,“忠”是我國(guó)古代倫理道德的最高原則,《左傳》中的“臨患不忘國(guó),忠也”,要人們盡自己最大努力,為維護(hù)國(guó)家利益而獻(xiàn)身,是積極的,對(duì)現(xiàn)實(shí)生活來(lái)說(shuō)就是財(cái)富,應(yīng)該提倡;而宋代的“君要臣死,臣不得不死”的封建忠君思想對(duì)現(xiàn)實(shí)生活來(lái)說(shuō)是包袱,應(yīng)該拋棄。2.繼承傳統(tǒng)文化的正確態(tài)度如何繼承傳統(tǒng)文化,發(fā)揮傳統(tǒng)文化的積極作用呢?正確的態(tài)度是:“取其精華,去其糟粕”,批判繼承,古為今用。面對(duì)傳統(tǒng)文化,要辯證地認(rèn)識(shí)它們?cè)诂F(xiàn)實(shí)生活屯的作用,分辨其中的精華和糟粕。對(duì)于傳統(tǒng)文化中符合社會(huì)發(fā)展要求的、積極向上的內(nèi)容,應(yīng)該繼續(xù)保持和發(fā)揚(yáng)。對(duì)于傳統(tǒng)文化中不符合社會(huì)發(fā)展要求的、落后的、腐朽的東西,必須“移風(fēng)易俗”,自覺(jué)地加以改造或剔除。

思考:在我們今天的生活中,應(yīng)該如何認(rèn)識(shí)“孝”道?(“孝”為中華民族傳統(tǒng)道德之本。在封建社會(huì),“孝”被異化為封建統(tǒng)治階級(jí)統(tǒng)治人民、維系政權(quán)的一個(gè)最重要的工具;一切聽(tīng)命于“一家之長(zhǎng)”的觀念,使人們往往屈從于獨(dú)斷的權(quán)威或傳統(tǒng)的家庭禮教,失去了獨(dú)立的人格。另一方面,“孝”從它本身意義出發(fā),所包含的尊老、敬老、養(yǎng)老,以及親親、愛(ài)人、愛(ài)國(guó),正是中華民族的一大傳統(tǒng)美德,是中華民族家庭和睦、鄰里相親、社會(huì)穩(wěn)定的重要內(nèi)在因素。因此,孝道已被列為中華傳統(tǒng)道德教育的重要內(nèi)容。)所以我們要辯證地認(rèn)識(shí)傳統(tǒng)文化在現(xiàn)實(shí)生活中的作用,做到“取其精華,去其糟粕;批判繼承,古為今用”。對(duì)于傳統(tǒng)文化中符合社會(huì)發(fā)展要求的、積極的、向上的內(nèi)容,應(yīng)該繼續(xù)保持和發(fā)揚(yáng)。對(duì)于傳統(tǒng)文化中不符合社會(huì)發(fā)展要求的、落后的、腐朽的東西,必須“移風(fēng)易俗”,自覺(jué)地加以改造或剔除。2、正確對(duì)待傳統(tǒng)文化的意義
