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(gè)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(shí),一般要結(jié)合圖形,運(yùn)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(yùn)算法則,逐步向基向量過(guò)渡,直至全部用基向量表示.3.在空間幾何體中選擇基底時(shí),通常選取公共起點(diǎn)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(zhǎng)方體、平行六面體、四面體中,一般選用從同一頂點(diǎn)出發(fā)的三條棱所對(duì)應(yīng)的向量作為基底.例2.在棱長(zhǎng)為2的正方體ABCD-A1B1C1D1中,E,F分別是DD1,BD的中點(diǎn),點(diǎn)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(gè)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(gè)正交基底.
傾斜角與斜率教學(xué)設(shè)計(jì)人教A版高中數(shù)學(xué)選擇性必修第一冊(cè)
(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(shí)實(shí)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(jì)算方法(1)判斷兩點(diǎn)的橫坐標(biāo)是否相等,若相等,則直線的斜率不存在.(2)若兩點(diǎn)的橫坐標(biāo)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(jìn)行計(jì)算.金題典例 光線從點(diǎn)A(2,1)射到y(tǒng)軸上的點(diǎn)Q,經(jīng)y軸反射后過(guò)點(diǎn)B(4,3),試求點(diǎn)Q的坐標(biāo)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(diǎn)Q的坐標(biāo)為 0,5/3 ,∴k入=kQA=(1"-" y)/2=-1/3.(方法2)設(shè)Q(0,y),如圖,點(diǎn)B(4,3)關(guān)于y軸的對(duì)稱點(diǎn)為B'(-4,3), kAB'=(1"-" 3)/(2+4)=-1/3,由題意得,A、Q、B'三點(diǎn)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(diǎn)Q的坐標(biāo)為(0,5/3).

人教版高中語(yǔ)文必修3《善待生命 學(xué)習(xí)論證》教案2篇
論證方法之引證法如何用好引證法：1.所引用的名言警句等針對(duì)性要強(qiáng)。每句名言都產(chǎn)生于特定的背景，都應(yīng)用于特定的交際目的，即使談同一個(gè)問(wèn)題，也有不少名言可供選取。2.要簡(jiǎn)潔，不宜過(guò)多。議論是在發(fā)表自己的見(jiàn)解而不是在介紹他人的見(jiàn)解。引用他人的話，目的是為了讓讀者更加信服自己的話。3.要注意直接引用和間接引用的區(qū)別。直接引用務(wù)求文字、甚至標(biāo)點(diǎn)均準(zhǔn)確無(wú)誤；間接引用只須述其大意，但要注意人稱的轉(zhuǎn)換。論證方法之喻證法喻證法是用設(shè)喻來(lái)論證論點(diǎn)的方法。在議論文中，設(shè)喻可以使論點(diǎn)更易懂、更風(fēng)趣、更容易獲得讀者的認(rèn)同。喻證法能化抽象為具體、化艱深為淺顯、化枯燥為生動(dòng)。論證方法之喻證法如何用好喻證法：1.以小見(jiàn)大，就近取譬。要精選生活中細(xì)小的、人們熟悉的事物做為設(shè)喻的喻體。2.喻體不求形似，只求神似。做為喻證的喻體與做為比喻的喻體不同。比喻的喻體是為了強(qiáng)調(diào)特征，描繪事物，側(cè)重形似，以形比形；而喻證的喻體是為了闡發(fā)觀點(diǎn)，以正視聽(tīng)，力求神似，以義取形。

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.

人教版新課標(biāo)高中物理必修1自由落體運(yùn)動(dòng)教案2篇
教學(xué)重點(diǎn)1．自由落體運(yùn)動(dòng)的概念及探究自由落體運(yùn)動(dòng)的過(guò)程。2．掌握自由落體運(yùn)動(dòng)規(guī)律，并能運(yùn)用其解決實(shí)際問(wèn)題。教學(xué)難點(diǎn)演示實(shí)驗(yàn)和探究實(shí)驗(yàn)的技巧及自由落體運(yùn)動(dòng)規(guī)律的得出.教學(xué)過(guò)程設(shè)計(jì)思想：1、 先用游戲激發(fā)學(xué)生學(xué)習(xí)興趣，順理成章地研究落體運(yùn)動(dòng)；2、 通過(guò)演示實(shí)驗(yàn)讓學(xué)生自己總結(jié)出物體下落快慢不同的主要原因是空氣阻力，從而猜想若沒(méi)有空氣阻力會(huì)怎樣；3、 用牛頓管實(shí)驗(yàn)驗(yàn)證猜想，引入了新的理想運(yùn)動(dòng)模型：自由落體運(yùn)動(dòng)。講述1971年宇航員做的實(shí)驗(yàn)，加深印象；4、 了解地球表面物體下落運(yùn)動(dòng)近似成自由落體運(yùn)動(dòng)的條件；5、 著手研究自由落體運(yùn)動(dòng)的規(guī)律，利用打點(diǎn)計(jì)時(shí)器進(jìn)行研究，得到結(jié)論；6、 總結(jié)自由落體運(yùn)動(dòng)特點(diǎn)及重力加速度；7、 應(yīng)用訓(xùn)練

①平動(dòng)的物體一般可以看作質(zhì)點(diǎn)做平動(dòng)的物體，由于物體上各點(diǎn)的運(yùn)動(dòng)情況相同，可以用一個(gè)點(diǎn)代表整個(gè)物體的運(yùn)動(dòng)，在這種情況下，物體的大小、形狀就無(wú)關(guān)緊要了，可以把整個(gè)物體當(dāng)質(zhì)點(diǎn)。例如：平直公路上行駛的汽車，車身上各部分的運(yùn)動(dòng)情況相同，當(dāng)我們把汽車作為一個(gè)整體來(lái)研究它的運(yùn)動(dòng)的時(shí)候，就可以把汽車當(dāng)作質(zhì)點(diǎn)。當(dāng)然，假如我們需要研究汽車輪胎的運(yùn)動(dòng)，由于輪胎上各部分運(yùn)動(dòng)情況不相同，那就不能把它看作質(zhì)點(diǎn)了。要注意的是：同一物體在不同情況下有時(shí)可看質(zhì)點(diǎn)，有時(shí)不可以看作質(zhì)點(diǎn)，一列火車從北京開(kāi)到上海，研究火車的運(yùn)行的時(shí)間，可將火車看成質(zhì)點(diǎn)，而火車過(guò)橋時(shí)，計(jì)算火車過(guò)橋的時(shí)間，不可以將火車看成質(zhì)點(diǎn)。②有轉(zhuǎn)動(dòng)但轉(zhuǎn)動(dòng)為次要因素例如：研究地球公轉(zhuǎn)時(shí)，可把地球看作質(zhì)點(diǎn)；研究地球自轉(zhuǎn)時(shí)，不能把地球看作質(zhì)點(diǎn)。③物體的形狀、大小可忽略再如：乒乓球旋轉(zhuǎn)對(duì)球的運(yùn)動(dòng)的較大的影響，運(yùn)動(dòng)員在發(fā)球、擊球時(shí)都要考慮，就不能把乒乓球簡(jiǎn)單看作質(zhì)點(diǎn)。

2、過(guò)程與方法（1）聯(lián)系生活實(shí)際，通過(guò)師生共同討論的方法來(lái)確定時(shí)刻與時(shí)間、位置、位移及其路程的關(guān)系。（2）通過(guò)類比的數(shù)學(xué)方法用數(shù)學(xué)上的點(diǎn)、線段來(lái)突破時(shí)刻與時(shí)間的關(guān)系，直線運(yùn)動(dòng)的位置和位移。（3）嘗試運(yùn)用所學(xué)的概念判斷一些與生活相關(guān)的實(shí)際問(wèn)題。3．情感態(tài)度與價(jià)值觀（1）通過(guò)本節(jié)課的學(xué)習(xí)，使學(xué)生體會(huì)到物理現(xiàn)象和規(guī)律所蘊(yùn)含的自然美。（2）通過(guò)對(duì)問(wèn)題的討論，培養(yǎng)學(xué)生勇于探究與日常生活有關(guān)的物理學(xué)問(wèn)題。（3）培養(yǎng)學(xué)生有主動(dòng)與他人合作的團(tuán)隊(duì)精神，提高學(xué)生的科學(xué)素養(yǎng)。二、教學(xué)重點(diǎn)、難點(diǎn)重點(diǎn)：1、時(shí)間、時(shí)刻、位置、位移的概念。2、矢量與標(biāo)量的概念。難點(diǎn)：1、時(shí)刻與時(shí)間、路程和位移的區(qū)別。2、用坐標(biāo)表示時(shí)刻、時(shí)間、位移的方法。3、矢量與標(biāo)量的區(qū)別。
人教版新課標(biāo)高中物理必修2向心加速度教案2篇
1．教材在學(xué)生的原有加速度概念的基礎(chǔ)上來(lái)討論“勻速圓周運(yùn)動(dòng)速度變化快慢”的問(wèn)題，讓學(xué)生知道向心加速度能夠表示勻速圓周運(yùn)動(dòng)物體速度變化的快慢究竟是怎么一回事。2．教材把向心加速度安排在線速度和角速度知識(shí)之后，使學(xué)生對(duì)描述勻速圓周運(yùn)動(dòng)的幾個(gè)物理量有一個(gè)大致的了解。3．教材從了解運(yùn)動(dòng)的規(guī)律過(guò)渡到了解力跟運(yùn)動(dòng)關(guān)系的規(guī)律；把向心加速度放在向心力之前，從運(yùn)動(dòng)學(xué)的角度來(lái)學(xué)習(xí)向心加速度。4．教材為了培養(yǎng)學(xué)生“用事實(shí)說(shuō)話”的“態(tài)度”，讓一切論述都合乎邏輯，改變了過(guò)去從向心力推導(dǎo)向心加速度的教學(xué)方式。1．采用理論、實(shí)驗(yàn)、體驗(yàn)相結(jié)合的教學(xué)安排。2．教師啟發(fā)引導(dǎo)，學(xué)生自主閱讀、思考，討論、交流。知識(shí)與技能1．會(huì)作矢量圖表示速度的變化量與速度之間的關(guān)系。2．加深理解加速度與速度、速度變化量的區(qū)別。3．體會(huì)勻速圓周運(yùn)動(dòng)向心加速度方向的分析方法。4．知道向心加速度的公式也適用于變速圓周運(yùn)動(dòng)；知道變速圓周運(yùn)動(dòng)的向心加速度的方向。
