我們知道數(shù)列是一種特殊的函數(shù)，在函數(shù)的研究中，我們在理解了函數(shù)的一般概念，了解了函數(shù)變化規(guī)律的研究內(nèi)容（如單調(diào)性，奇偶性等）后，通過研究基本初等函數(shù)不僅加深了對函數(shù)的理解，而且掌握了冪函數(shù)，指數(shù)函數(shù)，對數(shù)函數(shù)，三角函數(shù)等非常有用的函數(shù)模型。類似地，在了解了數(shù)列的一般概念后，我們要研究一些具有特殊變化規(guī)律的數(shù)列，建立它們的通項(xiàng)公式和前n項(xiàng)和公式，并應(yīng)用它們解決實(shí)際問題和數(shù)學(xué)問題，從中感受數(shù)學(xué)模型的現(xiàn)實(shí)意義與應(yīng)用，下面，我們從一類取值規(guī)律比較簡單的數(shù)列入手。新知探究1.北京天壇圜丘壇，的地面有十板布置，最中間是圓形的天心石，圍繞天心石的是9圈扇環(huán)形的石板，從內(nèi)到外各圈的示板數(shù)依次為9,18,27,36,45,54,63,72,81 ①2.S，M，L，XL，XXL，XXXL型號的女裝上對應(yīng)的尺碼分別是38,40,42,44,46,48 ②3.測量某地垂直地面方向上海拔500米以下的大氣溫度，得到從距離地面20米起每升高100米處的大氣溫度（單位℃）依次為25,24,23,22,21 ③

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.

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. Use this checklist to help your partner revise his/her draft.1.Does the writer explain why he/she changed/wanted to change?2.Does the writer tell how the changes have improved or will improve his/her life?3.Is the text well－organised?4.Does the writer use words and expressions to show similarities and differences?5.Are there any grammar or spelling errors?6.Does the writer use correct punctuation？

高中歷史人教版必修一《第22課祖國統(tǒng)一大業(yè)》說課稿
1、教材分析 本課選自普通高中課程標(biāo)準(zhǔn)實(shí)驗(yàn)教材，人民教育出版社歷史必修（1），第六單元：現(xiàn)代中國的政治建設(shè)與祖國統(tǒng)一，第22課——祖國統(tǒng)一大業(yè)。祖國統(tǒng)一始終是中國人民的共同夙愿。本課內(nèi)容主要敘述了“一國兩制”的偉大構(gòu)想，為完成祖國統(tǒng)一大業(yè)提出了一個創(chuàng)造性的指導(dǎo)方針。香港、澳門的回歸，是“一國兩制” 偉大構(gòu)想的成功實(shí)踐。在“一國兩制”方針指導(dǎo)下，海峽兩岸實(shí)現(xiàn)了一次歷史性的突破。揭示了“一國兩制” 的構(gòu)想，對推動完成祖國完全統(tǒng)一大業(yè)，實(shí)現(xiàn)中華民族偉大復(fù)興具有現(xiàn)實(shí)指導(dǎo)意義。 2、學(xué)情分析通過調(diào)查知道，學(xué)生對本節(jié)的基本史實(shí)有一定了解。但是，高一新生習(xí)慣于知識的記憶和教師的講解，不能深入分析歷史現(xiàn)象的內(nèi)涵和外延；不能進(jìn)一步探究事物的因果關(guān)系和理解事物的本質(zhì)；并且需要進(jìn)一步拓展思維的廣度和深度，實(shí)現(xiàn)從一維目標(biāo)到三維目標(biāo)的飛躍。
人教版高中語文必修1《人性光輝：寫人要凸顯個性》說課稿2篇
人教版新課標(biāo)教材必修一的“表達(dá)交流”部分，有一個專題是“人性的光輝——寫人要凸顯個性”。其中的“寫法借鑒”部分列舉了兩則人物描寫實(shí)例，并歸納出人物描寫的幾個要點(diǎn)。其訓(xùn)練的思路和方法是很明顯的，但所列舉的人物描寫的實(shí)例卻不夠典型。而必修一第三單元正好是學(xué)習(xí)寫人記事散文，其中的兩篇自讀課文《記梁任公先生的一次演講》《金岳霖先生》又是寫人記事非常典型的文章，故而我嘗試將這兩篇文章作為實(shí)例和。寫人要凸顯個性。寫作指導(dǎo)結(jié)合起來教學(xué)。這樣設(shè)計(jì)還有一個目的，那就是解決課程改革中教學(xué)內(nèi)容多而課時(shí)緊張的矛盾，提高課堂教學(xué)效率。師：今天，我們一起來學(xué)習(xí)“寫人要凸顯個性”。這兩堂課分四個步驟來完成：一、先學(xué)習(xí)教材中關(guān)于寫人方法的介紹，約15分鐘；二、快速閱讀第三單元的《記梁任公先生的一次演講》和《金岳霖先生》兩篇文章，具體感受其寫人的方法，約30分鐘；

師：在科學(xué)發(fā)展過程中，前一個理論體系的不完善之處，往往是新的研究和新的發(fā)現(xiàn)的突破口。開普勒之后，意大利天文學(xué)家伽利略創(chuàng)制了天文望遠(yuǎn)鏡，用更加精確的觀察繼續(xù)發(fā)展和驗(yàn)證哥白尼創(chuàng)立的新天文學(xué)理論。除了用望遠(yuǎn)鏡進(jìn)行天文觀察以外，伽利略還開始進(jìn)行自然科學(xué)的實(shí)驗(yàn)研究，哪位同學(xué)能給大家講一講伽利略在比薩斜塔上所作的關(guān)于物體自由下落的實(shí)驗(yàn)？生：（講述這一實(shí)驗(yàn)）師：所以，伽利略在科學(xué)方面更加重要的貢獻(xiàn)是奠定了近代實(shí)驗(yàn)科學(xué)的基礎(chǔ)。（2）實(shí)驗(yàn)科學(xué)和唯物主義師：伽利略從實(shí)踐上開辟了實(shí)驗(yàn)科學(xué)的方法，而英國唯物主義哲學(xué)家培根則從理論上闡述了實(shí)驗(yàn)科學(xué)的方法——?dú)w納法。培根和伽利略同被稱為實(shí)驗(yàn)科學(xué)之父，培根還有一句影響深刻的名言：“知識就是力量”，表明了他注重知識，尊崇科學(xué)的精神。我們再來概括一下意大利哲學(xué)家布魯諾的唯物主義思想，是否有同學(xué)可以簡述布魯諾的生平事跡？
