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

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？

反思感悟用基底表示空間向量的解題策略1.空間中,任一向量都可以用一個基底表示,且只要基底確定,則表示形式是唯一的.2.用基底表示空間向量時,一般要結(jié)合圖形,運用向量加法、減法的平行四邊形法則、三角形法則,以及數(shù)乘向量的運算法則,逐步向基向量過渡,直至全部用基向量表示.3.在空間幾何體中選擇基底時,通常選取公共起點最集中的向量或關(guān)系最明確的向量作為基底,例如,在正方體、長方體、平行六面體、四面體中,一般選用從同一頂點出發(fā)的三條棱所對應(yīng)的向量作為基底.例2.在棱長為2的正方體ABCD-A1B1C1D1中,E,F分別是DD1,BD的中點,點G在棱CD上,且CG=1/3 CD(1)證明:EF⊥B1C;(2)求EF與C1G所成角的余弦值.思路分析選擇一個空間基底,將(EF) ?,(B_1 C) ?,(C_1 G) ?用基向量表示.(1)證明(EF) ?·(B_1 C) ?=0即可;(2)求(EF) ?與(C_1 G) ?夾角的余弦值即可.(1)證明:設(shè)(DA) ?=i,(DC) ?=j,(DD_1 ) ?=k,則{i,j,k}構(gòu)成空間的一個正交基底.

(2)l的傾斜角為90°,即l平行于y軸,所以m+1=2m,得m=1.延伸探究1 本例條件不變,試求直線l的傾斜角為銳角時實數(shù)m的取值范圍.解:由題意知(m"-" 1"-" 1)/(m+1"-" 2m)>0,解得1<m<2.延伸探究2 若將本例中的“N(2m,1)”改為“N(3m,2m)”,其他條件不變,結(jié)果如何?解:(1)由題意知(m"-" 1"-" 2m)/(m+1"-" 3m)=1,解得m=2.(2)由題意知m+1=3m,解得m=1/2.直線斜率的計算方法(1)判斷兩點的橫坐標是否相等,若相等,則直線的斜率不存在.(2)若兩點的橫坐標不相等,則可以用斜率公式k=(y_2 "-" y_1)/(x_2 "-" x_1 )(其中x1≠x2)進行計算.金題典例 光線從點A(2,1)射到y(tǒng)軸上的點Q,經(jīng)y軸反射后過點B(4,3),試求點Q的坐標及入射光線的斜率.解:(方法1)設(shè)Q(0,y),則由題意得kQA=-kQB.∵kQA=(1"-" y)/2,kQB=(3"-" y)/4,∴(1"-" y)/2=-(3"-" y)/4.解得y=5/3,即點Q的坐標為 0,5/3 ,∴k入=kQA=(1"-" y)/2=-1/3.(方法2)設(shè)Q(0,y),如圖,點B(4,3)關(guān)于y軸的對稱點為B'(-4,3), kAB'=(1"-" 3)/(2+4)=-1/3,由題意得,A、Q、B'三點共線.從而入射光線的斜率為kAQ=kAB'=-1/3.所以,有(1"-" y)/2=(1"-" 3)/(2+4),解得y=5/3,點Q的坐標為(0,5/3).

新人教版高中英語必修3Unit 5 The Value of Money-Reading and Thinking教學(xué)設(shè)計一
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.

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
人教版新課標教材必修一的“表達交流”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例，并歸納出人物描寫的幾個要點。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)制了天文望遠鏡，用更加精確的觀察繼續(xù)發(fā)展和驗證哥白尼創(chuàng)立的新天文學(xué)理論。除了用望遠鏡進行天文觀察以外，伽利略還開始進行自然科學(xué)的實驗研究，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驗？生：（講述這一實驗）師：所以，伽利略在科學(xué)方面更加重要的貢獻是奠定了近代實驗科學(xué)的基礎(chǔ)。（2）實驗科學(xué)和唯物主義師：伽利略從實踐上開辟了實驗科學(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驗科學(xué)的方法——歸納法。培根和伽利略同被稱為實驗科學(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？

今天我說課的內(nèi)容是人教版高中物理必修1第四章第四節(jié)《力學(xué)單位制》，我的說課內(nèi)容將按下列程序展開。首先是本節(jié)教材的分析。一、說教材1、本節(jié)課在教材中的地位單位是學(xué)生在高考中最容易犯錯的地方之一，本節(jié)課內(nèi)容貫穿整個物理學(xué)科的每部分。學(xué)好這部分內(nèi)容對所有的自然學(xué)科都有幫助。2、教材簡析教材可分為：單位制等概念的來源和單位制的推廣。二、說教學(xué)目標：教學(xué)目標的設(shè)定是教師進行課堂授課的一個重要依據(jù)，是教師完成教學(xué)任務(wù)的鑒定標準。根據(jù)新課標要求和學(xué)生特點我對本節(jié)制定以下教學(xué)目標（1）了解什么是單位制，知道國際單位制中力學(xué)的三個基本單位。（2）認識單位制在物理學(xué)中和國際交往中的重要作用。（3）學(xué)會用單位運算來檢查物理公式推導(dǎo)的正確性，從而培養(yǎng)學(xué)生解決實際問題的能力。
人教版新課標高中物理必修1時間和位移說課稿2篇
研究一種物理現(xiàn)象，總是要先從現(xiàn)象的描述入手。機械運動作為自然界最簡單和最基本的運動形態(tài)，它所描述的是物體空間位置隨時間變化的情況。因此，本節(jié)學(xué)習(xí)描述質(zhì)點做機械運動需要時刻、時間間隔和位移等概念。相當一部分高一學(xué)生在具體過程中難以區(qū)別時刻和時間間隔。另外，由于思維的定式，在第一次接觸既要考慮大小又要考慮方向的問題時，會因不適應(yīng)造成學(xué)習(xí)困難。所以，區(qū)別“路程與位移”“時刻和時間間隔”是教學(xué)的重難點所在。學(xué)習(xí)這些內(nèi)容的過程與方法對學(xué)習(xí)速度和加速度可以起到奠定基礎(chǔ)的作用。教學(xué)的對象是高一的學(xué)生，這一時期的學(xué)生處在好奇善問、創(chuàng)新意識強烈的青少年期。對于生活中出現(xiàn)的各種現(xiàn)象具有濃厚的興趣。但他們的思維還停留在簡單的代數(shù)運算階段，對于矢量和矢量運算的理性認識幾乎沒有。且對生活中出現(xiàn)的時間、時刻、時間間隔等不能做出很好的區(qū)分，對時常提及的路程、距離等形成了模糊的前概念。

人教版新課標高中物理必修1自由落體運動說課稿2篇
學(xué)生回答的方法多樣，讓各小組根據(jù)自己討論出來的方法對自己實驗出來的紙帶進行數(shù)據(jù)處理，并求出加速度，并且將多條紙帶都進行處理，同時提醒學(xué)生對紙帶的選擇。接著，我會用多媒體展示重物下落實驗打出來的紙帶，用表格列出一段紙帶上各點的瞬時速度，準確畫出v-t圖像，求出加速度，將結(jié)果給予學(xué)生的結(jié)果作對比，確定出正確結(jié)論。最后讓學(xué)生分析總結(jié)：自由落體運動是初速度為零的勻加速直線運動，而且，多條紙帶算出來的加速度的數(shù)值都接近相等，即加速度在實驗誤差允許范圍內(nèi)是相等的。引出重力加速度，介紹概念、方向及大小。（強調(diào)“同一地點”，讓學(xué)生閱讀教材中一些地點的重力加速度，可以了解重力加速度的大小與緯度有關(guān)，緯度越大加速度越大）。學(xué)習(xí)了重力加速度后讓學(xué)生根據(jù)之前學(xué)習(xí)的勻變速直線運動公式推導(dǎo)出自由落體的運動規(guī)律。設(shè)計意圖：讓學(xué)生在學(xué)習(xí)過程中的主體地位和自主觀能動性得到充分發(fā)揮，取長補短，培養(yǎng)了學(xué)生的實驗操作能力，又使學(xué)生對自由落體運動的性質(zhì)有深刻的印象，從而解決了本節(jié)課第二個難點。
