1.判斷 (1)橢圓x^2/a^2 +y^2/b^2 =1(a>b>0)的長軸長是a. ( )(2)若橢圓的對稱軸為坐標(biāo)軸,長軸長與短軸長分別為10,8,則橢圓的方程為x^2/25+y^2/16=1. ( )(3)設(shè)F為橢圓x^2/a^2 +y^2/b^2 =1(a>b>0)的一個(gè)焦點(diǎn),M為其上任一點(diǎn),則|MF|的最大值為a+c(c為橢圓的半焦距). ( )答案:(1)× (2)× (3)√ 2.已知橢圓C:x^2/a^2 +y^2/4=1的一個(gè)焦點(diǎn)為(2,0),則C的離心率為( )A.1/3 B.1/2 C.√2/2 D.(2√2)/3解析:∵a2=4+22=8,∴a=2√2.∴e=c/a=2/(2√2)=√2/2.故選C.答案:C 三、典例解析例1已知橢圓C1:x^2/100+y^2/64=1,設(shè)橢圓C2與橢圓C1的長軸長、短軸長分別相等,且橢圓C2的焦點(diǎn)在y軸上.(1)求橢圓C1的半長軸長、半短軸長、焦點(diǎn)坐標(biāo)及離心率;(2)寫出橢圓C2的方程,并研究其性質(zhì).解:(1)由橢圓C1:x^2/100+y^2/64=1,可得其半長軸長為10,半短軸長為8,焦點(diǎn)坐標(biāo)為(6,0),(-6,0),離心率e=3/5.(2)橢圓C2:y^2/100+x^2/64=1.性質(zhì)如下:①范圍:-8≤x≤8且-10≤y≤10;②對稱性:關(guān)于x軸、y軸、原點(diǎn)對稱;③頂點(diǎn):長軸端點(diǎn)(0,10),(0,-10),短軸端點(diǎn)(-8,0),(8,0);④焦點(diǎn):(0,6),(0,-6);⑤離心率:e=3/5.

二、典例解析例5. 如圖，一種電影放映燈的反射鏡面是旋轉(zhuǎn)橢圓面（橢圓繞其對稱軸旋轉(zhuǎn)一周形成的曲面）的一部分。過對稱軸的截口 ABC是橢圓的一部分，燈絲位于橢圓的一個(gè)焦點(diǎn)F_1上，片門位另一個(gè)焦點(diǎn)F_2上，由橢圓一個(gè)焦點(diǎn)F_1 發(fā)出的光線，經(jīng)過旋轉(zhuǎn)橢圓面反射后集中到另一個(gè)橢圓焦點(diǎn)F_2，已知 〖BC⊥F_1 F〗_2，|F_1 B|=2.8cm, |F_1 F_2 |=4.5cm,試建立適當(dāng)?shù)钠矫嬷苯亲鴺?biāo)系，求截口ABC所在的橢圓方程(精確到0.1cm)典例解析解：建立如圖所示的平面直角坐標(biāo)系，設(shè)所求橢圓方程為x^2/a^2 +y^2/b^2 =1 (a>b>0) 在Rt ΔBF_1 F_2中,|F_2 B|= √(|F_1 B|^2+|F_1 F_2 |^2 )=√(〖2.8〗^2 〖+4.5〗^2 ) 有橢圓的性質(zhì) , |F_1 B|+|F_2 B|=2 a, 所以a=1/2(|F_1 B|+|F_2 B|)=1/2(2.8+√(〖2.8〗^2 〖+4.5〗^2 )) ≈4.1b= √(a^2 〖-c〗^2 ) ≈3.4所以所求橢圓方程為x^2/〖4.1〗^2 +y^2/〖3.4〗^2 =1 利用橢圓的幾何性質(zhì)求標(biāo)準(zhǔn)方程的思路1．利用橢圓的幾何性質(zhì)求橢圓的標(biāo)準(zhǔn)方程時(shí)，通常采用待定系數(shù)法，其步驟是：(1)確定焦點(diǎn)位置；(2)設(shè)出相應(yīng)橢圓的標(biāo)準(zhǔn)方程(對于焦點(diǎn)位置不確定的橢圓可能有兩種標(biāo)準(zhǔn)方程)；(3)根據(jù)已知條件構(gòu)造關(guān)于參數(shù)的關(guān)系式，利用方程(組)求參數(shù)，列方程(組)時(shí)常用的關(guān)系式有b2＝a2－c2等．

二、探究新知一、空間中點(diǎn)、直線和平面的向量表示1.點(diǎn)的位置向量在空間中,我們?nèi)∫欢c(diǎn)O作為基點(diǎn),那么空間中任意一點(diǎn)P就可以用向量(OP) ?來表示.我們把向量(OP) ?稱為點(diǎn)P的位置向量.如圖.2.空間直線的向量表示式如圖①,a是直線l的方向向量,在直線l上取(AB) ?=a,設(shè)P是直線l上的任意一點(diǎn),則點(diǎn)P在直線l上的充要條件是存在實(shí)數(shù)t,使得(AP) ?=ta,即(AP) ?=t(AB) ?.如圖②,取定空間中的任意一點(diǎn)O,可以得到點(diǎn)P在直線l上的充要條件是存在實(shí)數(shù)t,使(OP) ?=(OA) ?+ta, ①或(OP) ?=(OA) ?+t(AB) ?. ②①式和②式都稱為空間直線的向量表示式.由此可知,空間任意直線由直線上一點(diǎn)及直線的方向向量唯一確定.1.下列說法中正確的是( )A.直線的方向向量是唯一的B.與一個(gè)平面的法向量共線的非零向量都是該平面的法向量C.直線的方向向量有兩個(gè)D.平面的法向量是唯一的答案:B 解析:由平面法向量的定義可知,B項(xiàng)正確.

跟蹤訓(xùn)練1在正方體ABCD-A1B1C1D1中,E為AC的中點(diǎn).求證:(1)BD1⊥AC;(2)BD1⊥EB1.(2)∵(BD_1 ) ?=(-1,-1,1),(EB_1 ) ?=(1/2 "," 1/2 "," 1),∴(BD_1 ) ?·(EB_1 ) ?=(-1)×1/2+(-1)×1/2+1×1=0,∴(BD_1 ) ?⊥(EB_1 ) ?,∴BD1⊥EB1.證明:以D為原點(diǎn),DA,DC,DD1所在直線分別為x軸、y軸、z軸,建立如圖所示的空間直角坐標(biāo)系.設(shè)正方體的棱長為1,則B(1,1,0),D1(0,0,1),A(1,0,0),C(0,1,0),E(1/2 "," 1/2 "," 0),B1(1,1,1).(1)∵(BD_1 ) ?=(-1,-1,1),(AC) ?=(-1,1,0),∴(BD_1 ) ?·(AC) ?=(-1)×(-1)+(-1)×1+1×0=0.∴(BD_1 ) ?⊥(AC) ?,∴BD1⊥AC.例2在棱長為1的正方體ABCD-A1B1C1D1中,E,F,M分別為棱AB,BC,B1B的中點(diǎn).求證:D1M⊥平面EFB1.思路分析一種思路是不建系,利用基向量法證明(D_1 M) ?與平面EFB1內(nèi)的兩個(gè)不共線向量都垂直,從而根據(jù)線面垂直的判定定理證得結(jié)論;另一種思路是建立空間直角坐標(biāo)系,通過坐標(biāo)運(yùn)算證明(D_1 M) ?與平面EFB1內(nèi)的兩個(gè)不共線向量都垂直;還可以在建系的前提下,求得平面EFB1的法向量,然后說明(D_1 M) ?與法向量共線,從而證得結(jié)論.證明:(方法1)因?yàn)镋,F,M分別為棱AB,BC,B1B的中點(diǎn),所以(D_1 M) ?=(D_1 B_1 ) ?+(B_1 M) ?=(DA) ?+(DC) ?+1/2 (B_1 B) ?,而(B_1 E) ?=(B_1 B) ?+(BE) ?=(B_1 B) ?-1/2 (DC) ?,于是(D_1 M) ?·(B_1 E) ?=((DA) ?+(DC) ?+1/2 (B_1 B) ?)·((B_1 B) ?-1/2 (DC) ?)=0-0+0-1/2+1/2-1/4×0=0,因此(D_1 M) ?⊥(B_1 E) ?.同理(D_1 M) ?⊥(B_1 F) ?,又因?yàn)?B_1 E) ?,(B_1 F) ?不共線,因此D1M⊥平面EFB1.

盡管如此，農(nóng)民工作為一個(gè)新的社會階層，其獨(dú)特的經(jīng)濟(jì)需求和政治訴求應(yīng)該得到充分的尊重。雖然農(nóng)民工的“根”還在農(nóng)村，但是他們已經(jīng)脫胎換骨，日益成長為一個(gè)迫切需要社會認(rèn)可的新興階層。3.農(nóng)民工處于何種生存境況？作為“廉價(jià)勞動力”，工資水平低，拖欠時(shí)有發(fā)生。作為“超時(shí)勞動力”，工作時(shí)間極長，超負(fù)荷從事繁重工作。作為“高危勞動力”，社會保障缺失，各種安全事故頻繁。4.農(nóng)民工問題有多么重要？農(nóng)民工問題關(guān)系到農(nóng)業(yè)增效、農(nóng)民增收和農(nóng)村繁榮。農(nóng)民工問題關(guān)系到工業(yè)化、城鎮(zhèn)化和“以工補(bǔ)農(nóng)、以城促鄉(xiāng)”。農(nóng)民工問題關(guān)系到社會主義和諧社會建設(shè)。5.解決農(nóng)民工問題應(yīng)該做些什么？構(gòu)建城鄉(xiāng)一體化就業(yè)體系。健全農(nóng)民工權(quán)益保障制度。強(qiáng)化農(nóng)民工輸出地和輸入地培訓(xùn)。穩(wěn)妥解決農(nóng)民工戶籍問題。改進(jìn)對農(nóng)民工的管理和服務(wù)。

人教版高中歷史必修3文藝復(fù)興和宗教改革教案
三、宗教改革：1、背景：（1）文藝復(fù)興的影響。文藝復(fù)興中，人文主義學(xué)者盡管對宗教保持較為溫和的態(tài)度，但其以人為中心的思想極大地沖擊了天主教的精神獨(dú)裁，天主教的權(quán)威日益受到人們的懷疑。（2）天主教會對歐洲尤其是德意志的壓榨。中世紀(jì)的天主教會對人民進(jìn)行嚴(yán)密的精神統(tǒng)治，基督教信仰的核心是“原罪”和“靈魂救贖”，即人生下來就有罪，只有信仰上帝，跟隨耶穌才能得救。就“靈魂救贖”而言，最初強(qiáng)調(diào)的是個(gè)人信仰的作用，后來，神學(xué)家們又加上了種種繁雜的宗教禮儀，而且必須得到神職人員的幫助，靈魂才能得救。在經(jīng)濟(jì)上，天主教會還是最大的封建主，占有大量的土地，并征收什一稅，對各國人民大肆搜刮。羅馬教廷每年從德意志搜刮的財(cái)富達(dá)30萬古爾登（貨幣單位），相當(dāng)于“神圣羅馬帝國”皇帝每年稅收額的20倍。德意志也成了被教會榨取最嚴(yán)重的地區(qū)，素有“教皇的乳?！敝Q。

人教版高中歷史必修3“罷黜百家獨(dú)尊儒術(shù)”教案2篇
戰(zhàn)國陰陽五行家鄒衍認(rèn)為，歷史中的朝代更替是由于五德運(yùn)行產(chǎn)生的影響。按照鄒衍的學(xué)說，每個(gè)朝代必須與五德之一相連，因此，這個(gè)朝代就應(yīng)當(dāng)遵循這五德之一的要求來運(yùn)轉(zhuǎn)。董仲舒修改了這個(gè)理論，認(rèn)為朝代的更替不是依循五德運(yùn)行的順序，而是依循“三統(tǒng)”，即黑統(tǒng)、白統(tǒng)、赤統(tǒng)的順序。他在《三代改制質(zhì)文》中說：每個(gè)朝代都依循一統(tǒng)，每統(tǒng)又各有其為政的系統(tǒng)。按董仲舒的說法，夏朝代表黑統(tǒng)，商朝代表白統(tǒng)；周朝則是赤統(tǒng)。夏、商、周三朝完成了這一歷史循環(huán)。之后，歷史又開始一次新的循環(huán)，新的朝代又應(yīng)當(dāng)代表黑統(tǒng)。繼承周朝統(tǒng)治的既不是秦朝，也不是漢朝，而是孔子，他承受天命，創(chuàng)立了黑統(tǒng)?？鬃铀芴烀皇且环N“法統(tǒng)”，而是一種“道統(tǒng)”。董仲舒說：“《春秋》大一統(tǒng)者，天地之常經(jīng)，古今之通誼也。今師異道，人異論，百家殊方，指意不同，是以上亡以持一統(tǒng)；法制數(shù)變，下不知所守。臣愚以為諸不在六藝之科孔子之術(shù)者，皆絕其道，勿使并進(jìn)。邪辟之說滅息，然后統(tǒng)紀(jì)可一而法度可明，民知所從矣。”
