Example:One day, a poor boy who was trying to pay his way through school by sending newspapers door to door found that he only had one dime(一角）left. He was so hungry that he decided to beg for a meal at the next house.However, he lost his nerve when a lovely young woman opened the door. Instead of a meal he asked for a drink of water. She thought he looked hungry so she brought him a large glass of milk. He drank it slowly, and then asked, “How much do I owe you?” “You don’t owe me anything,” she replied, “Mother has taught me never to accept pay for a kindness.” “Then I thank you from the bottom of my heart.” With these words, Howard Kelly left that house.Years later the woman became badly ill and was finally sent to the hospital in a big city. Dr. Howard Kelly, now famous, was called in. When he heard the name of the town she came from, a strange light filled his eyes. Dressed in his doctor’s clothes, Dr. Kelly went into her room and recognized her at once. From that day on, he gave special attention to her, and decided to do his best to save her life.At last the woman was saved. Dr. Kelly asked the business office to pass the final bill to him. He looked at it and then wrote something on the side. The bill was sent to the woman’s room. She was afraid to open it because she was sure that it would take the rest of her life to pay for it off. Finally she looked, and the note on the side of the bill caught her attention. She read these words: “Paid in full with a glass of milk, Dr. Howard Kelly.” Tear of joy flooded her eyes.

新人教版高中英語必修3Unit 4 Space Exploration-Listening&Speaking＆Talking教學設(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？

從右圖“進出口貿(mào)易占全國的比重”可看出，珠三角地區(qū)的外向型經(jīng)濟特征很明顯，但正在緩慢的發(fā)生轉(zhuǎn)變；而長三角地區(qū)的外貿(mào)依存度在10年內(nèi)迅速增長。由此可見，珠三角地區(qū)城市化過程，是伴隨著該地特殊的經(jīng)濟發(fā)展相對自發(fā)地快速推進，缺乏宏觀而理性的規(guī)劃。閱讀通過此閱讀材料，使學生大致了解以下內(nèi)容深圳作為珠江三角洲地區(qū)迅速城市化的一個典型代表，到目前為止，對其未來發(fā)展道路的構(gòu)想，主要集中在：如何聯(lián)合和依托臨近區(qū)域、聯(lián)合優(yōu)勢資源，擴大發(fā)展空間；如何明確功能，重新定位，合理分工，突出特色?；顒娱L江三角洲地區(qū)城市的協(xié)調(diào)發(fā)展1．讀圖4．28，如果按人口規(guī)模>500萬人、100萬～500萬人、50萬～100萬人、20萬～50萬人和<20萬人將城市分為五級的話，分析長江三角洲地區(qū)城市的等級規(guī)模結(jié)構(gòu)是否合理，這對其城市的協(xié)調(diào)發(fā)展有何影響?

雙曲線及其標準方程教學設(shè)計人教A版高中數(shù)學選擇性必修第一冊
∵在△EFP中,|EF|=2c,EF上的高為點P的縱坐標,∴S△EFP=4/3c2=12,∴c=3,即P點坐標為(5,4).由兩點間的距離公式|PE|=√("(" 5+3")" ^2+4^2 )=4√5,|PF|=√("(" 5"-" 3")" ^2+4^2 )=2√5,∴a=√5.又b2=c2-a2=4,故所求雙曲線的方程為x^2/5-y^2/4=1.5.求適合下列條件的雙曲線的標準方程.(1)兩個焦點的坐標分別是(-5,0),(5,0),雙曲線上的點與兩焦點的距離之差的絕對值等于8;(2)以橢圓x^2/8+y^2/5=1長軸的端點為焦點,且經(jīng)過點(3,√10);(3)a=b,經(jīng)過點(3,-1).解:(1)由雙曲線的定義知,2a=8,所以a=4,又知焦點在x軸上,且c=5,所以b2=c2-a2=25-16=9,所以雙曲線的標準方程為x^2/16-y^2/9=1.(2)由題意得,雙曲線的焦點在x軸上,且c=2√2.設(shè)雙曲線的標準方程為x^2/a^2 -y^2/b^2 =1(a>0,b>0),則有a2+b2=c2=8,9/a^2 -10/b^2 =1,解得a2=3,b2=5.故所求雙曲線的標準方程為x^2/3-y^2/5=1.(3)當焦點在x軸上時,可設(shè)雙曲線方程為x2-y2=a2,將點(3,-1)代入,得32-(-1)2=a2,所以a2=b2=8.因此,所求的雙曲線的標準方程為x^2/8-y^2/8=1.當焦點在y軸上時,可設(shè)雙曲線方程為y2-x2=a2,將點(3,-1)代入,得(-1)2-32=a2,a2=-8,不可能,所以焦點不可能在y軸上.綜上,所求雙曲線的標準方程為x^2/8-y^2/8=1.

二、探究新知一、點到直線的距離、兩條平行直線之間的距離1.點到直線的距離已知直線l的單位方向向量為μ,A是直線l上的定點,P是直線l外一點.設(shè)(AP) ?=a,則向量(AP) ?在直線l上的投影向量(AQ) ?=(a·μ)μ.點P到直線l的距離為PQ=√(a^2 "-(" a"·" μ")" ^2 ).2.兩條平行直線之間的距離求兩條平行直線l,m之間的距離,可在其中一條直線l上任取一點P,則兩條平行直線間的距離就等于點P到直線m的距離.點睛：點到直線的距離,即點到直線的垂線段的長度,由于直線與直線外一點確定一個平面,所以空間點到直線的距離問題可轉(zhuǎn)化為空間某一個平面內(nèi)點到直線的距離問題.1.已知正方體ABCD-A1B1C1D1的棱長為2,E,F分別是C1C,D1A1的中點,則點A到直線EF的距離為 . 答案: √174/6解析:如圖,以點D為原點,DA,DC,DD1所在直線分別為x軸、y軸、z軸建立空間直角坐標系,則A(2,0,0),E(0,2,1),F(1,0,2),(EF) ?=(1,-2,1),

從國際法角度看，國際社會的每一個主權(quán)國家應(yīng)該是一律平等的，但是，在現(xiàn)實的國際關(guān)系中，每個國家的國際地位、國際影響力，歷來都是由國家力量決定的。國家力量發(fā)生變化，也會引起國際關(guān)系的變化。經(jīng)濟、科技落后，軍力不強，國內(nèi)政局不安，它的國際影響力、參與力就不強。正因為如此，某些發(fā)達國家往往以其強大的國家力量為后盾，推行霸權(quán)主義、強權(quán)政治。二、維護我國的國家利益教師活動：閱讀教材第100頁內(nèi)容，思考討論為什么要維護我國的國家利益？我國的國家利益包括哪些內(nèi)容？學生活動：認真思考并積極討論，踴躍發(fā)言1、原因我國是人民當家作主的社會主義國家，國家利益與人民的根本利益相一致。維護我國的國家利益就是維護廣大人民的根本利益，具有正當性和正義性。2、內(nèi)容我國國家利益的主要內(nèi)容包括：安全利益，如國家的統(tǒng)一、獨立、主權(quán)和領(lǐng)土完整；政治利益，如我國政治、經(jīng)濟、文化等制度的鞏固；經(jīng)濟利益，如我國資源利用的效益、經(jīng)濟活動的利益和國家物質(zhì)基礎(chǔ)的增強等。

知識目標1.了解傳統(tǒng)工業(yè)區(qū)的分布、條件和工業(yè)部門。2.掌握傳統(tǒng)的魯爾工業(yè)區(qū)優(yōu)越的區(qū)位條件，了解它的衰落原因及其綜合整治途徑。能力目標1.讀圖分析礦產(chǎn)資源與工業(yè)部門之間的聯(lián)系，培養(yǎng)學生的地理思維能力、綜合分析能力，明確工業(yè)生產(chǎn)也應(yīng)因地制宜。2.聯(lián)系實際，了解當?shù)貍鹘y(tǒng)工業(yè)發(fā)展狀況，為適應(yīng)當今世界經(jīng)濟發(fā)展狀況，應(yīng)有哪些改善措施，培養(yǎng)學生的創(chuàng)新能力。德育目標1.通過了解魯爾區(qū)的發(fā)展變化，用發(fā)展的觀點看待傳統(tǒng)工業(yè)區(qū)的改造，適應(yīng)世界發(fā)展潮流。2.中國已經(jīng)“入世”，我們應(yīng)用辯證唯物主義觀點分析我國傳統(tǒng)工業(yè)今后遇到的機遇和挑戰(zhàn)。

觀察實驗視頻實驗驗證師：其實大家完全可以利用身邊的器材來驗證。實驗1、用彈簧秤掛上鉤碼，然后迅速上提和迅速下放?，F(xiàn)象：在鉤碼被迅速上提的一瞬間，彈簧秤讀數(shù)突然變大；在鉤碼被迅速下放的一瞬間，彈簧秤讀數(shù)突然變小。師：迅速上提時彈簧秤示數(shù)變大是超重還是失重？迅速下放時彈簧秤示數(shù)變小是超重還是失重？生：迅速上提超重，迅速下放失重。體會為何用彈簧秤測物體重力時要保證在豎直方向且保持靜止或勻速實驗2、學生站在醫(yī)用體重計上，觀察下蹲和站起時秤的示數(shù)如何變化？在實驗前先讓同學們理論思考示數(shù)會如何變化再去驗證，最后再思考。（1）在上升過程中可分為兩個階段：加速上升、減速上升；下蹲過程中也可分為兩個階段：加速下降、減速下降。（2）當學生加速上升和減速下降時會出現(xiàn)超重現(xiàn)象；當學生加速下降和減速上升時會出現(xiàn)失重現(xiàn)象；（3）出現(xiàn)超重現(xiàn)象時加速度方向向上，出現(xiàn)失重現(xiàn)象時加速度方向向下。完全失重
