新人教版高中英語必修3Unit 5 The Value of Money-Reading and Thinking教學設(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.

空間向量及其運算的坐標表示教學設(shè)計人教A版高中數(shù)學選擇性必修第一冊
一、情境導學我國著名數(shù)學家吳文俊先生在《數(shù)學教育現(xiàn)代化問題》中指出:“數(shù)學研究數(shù)量關(guān)系與空間形式,簡單講就是形與數(shù),歐幾里得幾何體系的特點是排除了數(shù)量關(guān)系,對于研究空間形式,你要真正的‘騰飛’,不通過數(shù)量關(guān)系,我想不出有什么好的辦法…….”吳文俊先生明確地指出中學幾何的“騰飛”是“數(shù)量化”,也就是坐標系的引入,使得幾何問題“代數(shù)化”,為了使得空間幾何“代數(shù)化”,我們引入了坐標及其運算.二、探究新知一、空間直角坐標系與坐標表示1.空間直角坐標系在空間選定一點O和一個單位正交基底{i,j,k},以點O為原點,分別以i,j,k的方向為正方向、以它們的長為單位長度建立三條數(shù)軸:x軸、y軸、z軸,它們都叫做坐標軸.這時我們就建立了一個空間直角坐標系Oxyz,O叫做原點,i,j,k都叫做坐標向量,通過每兩個坐標軸的平面叫做坐標平面,分別稱為Oxy平面,Oyz平面,Ozx平面.
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.

由于這部分知識已要求學生在課前收集相關(guān)資料探討分析，，現(xiàn)在提供機會讓他們進行交流，充分發(fā)表各自的見解。所以，學生對這個知識掌握起來并不難。所以，我對這部分內(nèi)容不做太多的講解，只要做進一步的梳理，加深學生的理解即可。 第三是小結(jié)環(huán)節(jié) 在學生對西氣東輸工程的原因掌握之后進入的是小結(jié)環(huán)節(jié)，這里我進一步提出問題：在西氣東輸工程段的建設(shè)中有沒有什么難關(guān)？ 通過西氣東輸?shù)碾y度了解，間接的表現(xiàn)我國的科技的發(fā)展，增加學生的愛國情，同時也說明西氣東輸?shù)慕ǔ梢灿屑夹g(shù)這一原因。從而也完成了本課時的小結(jié)。 第四環(huán)節(jié)是作業(yè)布置 在這里要求學生課后預習本課剩下的內(nèi)容：思考西氣東輸對區(qū)域發(fā)展的影響以及為何要實施資源的跨區(qū)域調(diào)配。通過這樣的問題一方面為下節(jié)課學習奠定基礎(chǔ)，另一方面體現(xiàn)本課學習從“個”到“類”從特殊到一般的過程。
