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, 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.

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.

1、我先講故事給幼兒聽,讓他們理解朋友的含義老師出示與朋友合影的照片,講一講與好朋友在一起的情景,趣事。(突出一起分享主題)幼兒討論:好朋友在一起應(yīng)該怎樣?懂得好東西一起分享。介紹自己的小物品,嘗試與朋友分享。今天小朋友們都把自己喜歡的小物品帶來了,請(qǐng)你給大家說說你的物品是什么?怎樣玩?你們帶來的小物品太好玩了,你的朋友也想玩一玩,快去找個(gè)朋友交換著玩,這樣你就會(huì)有更多個(gè)玩具了。播放背景音樂,引導(dǎo)幼兒自由結(jié)伴交換物品進(jìn)行分享。老師注意引導(dǎo)幼兒能和更多的小朋友進(jìn)行分享,進(jìn)一步體會(huì)到分享的意義。講一講分享中發(fā)生的趣事,體驗(yàn)分享的樂趣。你和誰交換的,你們是怎樣玩的?心里有什么感覺?有不愉快的事情發(fā)生嗎?你們是怎樣解決的?
甲方因生產(chǎn)經(jīng)營需要,經(jīng)考核,錄用乙方 (姓名)為 (工程名稱)工人,遵照國家有關(guān)勞動(dòng)法律法規(guī),經(jīng)雙方協(xié)商,簽訂本合同?! 〉谝粭l 甲方錄用乙方從事 (工作名稱)。 第二條 勞動(dòng)合同期限從 年 月 日起至 年 月 日時(shí)止。其中試用期限為 個(gè)月,至 年 月 日止。
日趨嚴(yán)重的白色污染正不斷的威脅著人類及其它生物的生存環(huán)境,尤其是占據(jù)半壁江山的難降物塑料袋,已日益引起了人們的關(guān)注。2008年伊始,國務(wù)院辦公廳下發(fā)《關(guān)于限制生產(chǎn)銷售使用塑料購物袋的通知》,指出自2008年6月1日起,在全國范圍內(nèi)禁止生產(chǎn)、銷售、使用厚度低于0.025毫米的塑料購物袋。作為現(xiàn)實(shí)生活中的普通人,雖然不可能都直接從事環(huán)保工作,但作為老師的我們應(yīng)該用各種方式讓幼兒獲得正確的體驗(yàn),讓他們深入了解塑料袋,了解此政策的重要意義,畢竟幼兒是未來的主力軍,讓他們成為環(huán)保的宣傳者、執(zhí)行者,并將良好的習(xí)慣泛化到周圍人身上,并從中找到快樂。
教材分析:《小鳥小鳥你真好》是省編教材大班上學(xué)期中的一首歌曲,是一首優(yōu)美、抒情、動(dòng)聽,充滿愛的歌曲,它描述了老鳥為了小鳥辛苦了一輩子,現(xiàn)在老了,行動(dòng)方面已經(jīng)不方便,再去捉蟲真的很困難,造成了生活上的問題。小鳥長大了,懂得了老鳥的困境,不怕辛苦,總是照顧著老鳥,每次捉蟲的時(shí)候,總是讓老鳥先吃飽。體現(xiàn)了小鳥尊敬長輩,照顧長輩的美德。歌曲是2/4拍節(jié)奏。我們知道,節(jié)奏是音樂要素之一。因此,知識(shí)點(diǎn)是2/4拍節(jié)奏的強(qiáng)弱特點(diǎn)。歌曲還運(yùn)用了領(lǐng)唱、齊唱的方法,表現(xiàn)了老鳥和小鳥的情感;還運(yùn)用了兩個(gè)間奏以及多處付點(diǎn)音符,掌握好這些知識(shí)點(diǎn),為整個(gè)教學(xué)活動(dòng)的開展奠定了基礎(chǔ)。
序數(shù)是表示集合中元素次序的數(shù),是用自然數(shù)表示事物排列的次序,讓幼兒回答“第幾”的問題。認(rèn)識(shí)序數(shù)要以認(rèn)識(shí)基數(shù)為基礎(chǔ)。本班幼兒已學(xué)習(xí)了10以內(nèi)初步數(shù)概念的數(shù)序,為學(xué)習(xí)序數(shù)做好了準(zhǔn)備。學(xué)習(xí)序數(shù)不必像學(xué)習(xí)基數(shù)那樣逐個(gè)數(shù)地形成概念,因此可以分兩段集中學(xué)習(xí)10以內(nèi)的序數(shù),先學(xué)5以內(nèi)的序數(shù),再學(xué)10以內(nèi)的序數(shù),本節(jié)課就將內(nèi)容定為學(xué)習(xí)5以內(nèi)的序數(shù)。學(xué)習(xí)序數(shù)要求能從不同方向(從左到右,從右到左,從上到下,從下到上)確認(rèn)物體的排列次序。由于本節(jié)課是第一次接觸序數(shù),老師就降低了要求,即從左到右,從下到上來排列物體的次序,這符合幼兒的認(rèn)知經(jīng)驗(yàn)。在生活中,幼兒已習(xí)慣這兩個(gè)方向來排列物體的次序。數(shù)數(shù)是從左到右數(shù)的,樓層是從下到上數(shù),避免了逆排序造成的干擾。
《小烏龜上幼兒園》這個(gè)故事選自于小班上學(xué)期望整合(一),這一主題中,該故事選用了小朋友生活中比較熟悉并喜歡的小烏龜、小青蛙、小鴨子、小雞為角色。講述了一只小烏龜?shù)谝惶焐嫌變簣@的心情及所發(fā)生的事情,最終小烏龜能快樂地和同伴玩,融入到了集體當(dāng)中的故事?,F(xiàn)獨(dú)生子女較多,其有較多的幼兒都是爺爺、奶奶帶,因此,都比較嬌氣;并且接觸外面的生活較少加上年齡較小,未離開過家長。因此,剛踏入陌生的環(huán)境中,難免會(huì)哭鬧得厲害。為了能使幼兒更快地適應(yīng)新環(huán)境,我覺得這個(gè)故事既符合小班幼兒年齡特點(diǎn),又符合孩子的現(xiàn)實(shí)需要。所以我選擇了這個(gè)故事來安撫幼兒情緒,并將它與語言和社會(huì)兩大領(lǐng)域相結(jié)合。
