圓與圓的位置關(guān)系教學(xué)設(shè)計(jì)人教A版高中數(shù)學(xué)選擇性必修第一冊(cè)
1.兩圓x2+y2-1=0和x2+y2-4x+2y-4=0的位置關(guān)系是( )A.內(nèi)切 B.相交 C.外切 D.外離解析:圓x2+y2-1=0表示以O(shè)1(0,0)點(diǎn)為圓心,以R1=1為半徑的圓.圓x2+y2-4x+2y-4=0表示以O(shè)2(2,-1)點(diǎn)為圓心,以R2=3為半徑的圓.∵|O1O2|=√5,∴R2-R1<|O1O2|<R2+R1,∴圓x2+y2-1=0和圓x2+y2-4x+2y-4=0相交.答案:B2.圓C1:x2+y2-12x-2y-13=0和圓C2:x2+y2+12x+16y-25=0的公共弦所在的直線方程是 . 解析:兩圓的方程相減得公共弦所在的直線方程為4x+3y-2=0.答案:4x+3y-2=03.半徑為6的圓與x軸相切,且與圓x2+(y-3)2=1內(nèi)切,則此圓的方程為( )A.(x-4)2+(y-6)2=16 B.(x±4)2+(y-6)2=16C.(x-4)2+(y-6)2=36 D.(x±4)2+(y-6)2=36解析:設(shè)所求圓心坐標(biāo)為(a,b),則|b|=6.由題意,得a2+(b-3)2=(6-1)2=25.若b=6,則a=±4;若b=-6,則a無(wú)解.故所求圓方程為(x±4)2+(y-6)2=36.答案:D4.若圓C1:x2+y2=4與圓C2:x2+y2-2ax+a2-1=0內(nèi)切,則a等于 . 解析:圓C1的圓心C1(0,0),半徑r1=2.圓C2可化為(x-a)2+y2=1,即圓心C2(a,0),半徑r2=1,若兩圓內(nèi)切,需|C1C2|=√(a^2+0^2 )=2-1=1.解得a=±1. 答案:±1 5. 已知兩個(gè)圓C1:x2+y2=4,C2:x2+y2-2x-4y+4=0,直線l:x+2y=0,求經(jīng)過(guò)C1和C2的交點(diǎn)且和l相切的圓的方程.解:設(shè)所求圓的方程為x2+y2+4-2x-4y+λ(x2+y2-4)=0,即(1+λ)x2+(1+λ)y2-2x-4y+4(1-λ)=0.所以圓心為 1/(1+λ),2/(1+λ) ,半徑為1/2 √((("-" 2)/(1+λ)) ^2+(("-" 4)/(1+λ)) ^2 "-" 16((1"-" λ)/(1+λ))),即|1/(1+λ)+4/(1+λ)|/√5=1/2 √((4+16"-" 16"(" 1"-" λ^2 ")" )/("(" 1+λ")" ^2 )).解得λ=±1,舍去λ=-1,圓x2+y2=4顯然不符合題意,故所求圓的方程為x2+y2-x-2y=0.

一、教材分析1、本框題在教材中的地位。本框題教材所處的地位及聯(lián)系：《關(guān)于世界觀的學(xué)說(shuō)》是人教版2004年12月第一版教材高二政治必修4第一單元第二框題，在這之前學(xué)生已經(jīng)學(xué)習(xí)了生活處處有哲學(xué)的內(nèi)容，了解了哲學(xué)與我們的生活息息相關(guān)，這為過(guò)度到本框題的學(xué)習(xí)起到了鋪墊的作用。本框題又是學(xué)生進(jìn)入哲學(xué)的入門，因而它在生活與哲學(xué)中具有不容忽視的重要地位。學(xué)好本框題，為學(xué)生從總體上對(duì)哲學(xué)的理解，為以后學(xué)好哲學(xué)做了良好的鋪墊作用。本框題是進(jìn)入哲學(xué)與生活不可缺少的部分，也學(xué)生的學(xué)習(xí)生活常常遇到的問(wèn)題。2、教學(xué)目標(biāo)：1. 知識(shí)目標(biāo)：（1）哲學(xué)的含義；（2）哲學(xué)與世界觀的關(guān)系；（3）哲學(xué)與具體科學(xué)知識(shí)的關(guān)系。2. 能力目標(biāo)：（1）通過(guò)對(duì)哲學(xué)與世界觀、方法論、具體知識(shí)三對(duì)關(guān)系的分析，培養(yǎng)辯證思維的能；（2）通過(guò)對(duì)身邊生活事例、哲理故事、哲學(xué)家觀點(diǎn)的體悟，培養(yǎng)分析問(wèn)題的能力；

一、設(shè)計(jì)理念教學(xué)設(shè)計(jì)堅(jiān)持少講多學(xué)、以學(xué)為主的教學(xué)理念，重視學(xué)培養(yǎng)生的學(xué)習(xí)興趣，要充分調(diào)動(dòng)學(xué)生學(xué)習(xí)的積極性和主動(dòng)性，充分發(fā)揮學(xué)生的主體性。教師要以組織者、引導(dǎo)者、合作者的角色參與到教學(xué)活動(dòng)中去。力圖通過(guò)導(dǎo)學(xué)案努力培養(yǎng)學(xué)生的自學(xué)習(xí)慣和自學(xué)能力。二、教材分析與處理1、教材的地位與作用：必修三第三單元所選的文言文都是古代的議論性散文。本課是“唐宋八大家”之首、中唐古文運(yùn)動(dòng)的倡導(dǎo)者韓愈的力作，是唐宋散文中的名篇，具有很強(qiáng)的代表性。通過(guò)這篇自讀課的學(xué)習(xí)，能使學(xué)生了解唐宋散文的風(fēng)貌，更能使學(xué)生進(jìn)一步積累文言文基礎(chǔ)知識(shí)，提高學(xué)生的文言文閱讀欣賞能力，從而提升學(xué)生的文言文自讀能力。2、教學(xué)目標(biāo)：《高中語(yǔ)文課程標(biāo)準(zhǔn)》要求高中學(xué)生能閱讀淺易文言文，能借助注釋和工具書(shū)，理解詞句含義，讀懂文章內(nèi)容；了解并梳理常見(jiàn)的文言實(shí)詞、文言虛詞、文言句式的意義或用法，注重在閱讀實(shí)踐中舉一反三；對(duì)文章有一定的分析欣賞能力。高一的學(xué)生對(duì)于文言文的知識(shí)還在積累階段，應(yīng)該注重基礎(chǔ)知識(shí)的積累和一定量的誦讀。對(duì)此，我將教學(xué)目標(biāo)確定為：

教學(xué)過(guò)程：（一）導(dǎo)入：課前放《愛(ài)的奉獻(xiàn)》歌曲，同時(shí)不斷播放一些有關(guān)“愛(ài)”的主題的圖片，渲染一種情感氛圍。師說(shuō)：同學(xué)們，誰(shuí)能說(shuō)說(shuō)這組圖片的主題應(yīng)該是什么？生（七嘴八舌）：母愛(ài)，不對(duì)是親情……是友情、還有人與人互相幫助……那組軍人圖片是說(shuō)保衛(wèi)國(guó)家，應(yīng)該是愛(ài)國(guó)……那徐本禹和感動(dòng)中國(guó)呢？…………生答：是關(guān)于愛(ài)的方面師說(shuō)：不錯(cuò)，是關(guān)于愛(ài)的方面。那么同學(xué)們，今天就以“愛(ài)的奉獻(xiàn)”為話題，來(lái)寫(xiě)一篇議論文如何？生答：老師，還是寫(xiě)記敘文吧。生答：就是，要不議論文寫(xiě)出來(lái)也象記敘文。師問(wèn)：為什么？生答：老師，這個(gè)話題太有話說(shuō)了，一舉例子就收不住了，怎么看怎么象記敘文。生答：就是，再用一點(diǎn)形容詞，就更象了。眾人樂(lè)。師說(shuō)：那么同學(xué)們誰(shuí)能告訴我，為什么會(huì)出現(xiàn)這種問(wèn)題？一生小聲說(shuō)：還不是我們笨，不會(huì)寫(xiě)。師說(shuō)：不是笨，也不是不會(huì)寫(xiě)，你們想為什么記敘文就會(huì)寫(xiě)，一到議論文就不會(huì)了，那是因?yàn)橥瑢W(xué)們沒(méi)有明白議論文中的記敘與記敘文中的記敘有什么不同，所以一寫(xiě)起議論文中的記敘，還是按照記敘文的寫(xiě)法寫(xiě)作，這自然就不行了。那好，今天我們就從如何寫(xiě)議論文中的記敘講起。

在學(xué)生活動(dòng)的基礎(chǔ)上，教師總結(jié)歸納：要堅(jiān)持從群眾中來(lái)到群眾中去的工作方法。要求：政府要通過(guò)各種途徑，利用各種群眾組織、社會(huì)團(tuán)體廣泛收集群眾意見(jiàn)和建議，認(rèn)真對(duì)待群眾的來(lái)信來(lái)訪。還要為群眾誠(chéng)心誠(chéng)意辦實(shí)事，盡心竭力解難事，堅(jiān)持不懈。通過(guò)合作探究，以此來(lái)培養(yǎng)學(xué)生的分析能力，探究能力以及透過(guò)現(xiàn)象看本質(zhì)的能力，培養(yǎng)學(xué)生獲取信息的能力，自主學(xué)習(xí)的能力以及全面看問(wèn)題的能力，再結(jié)合教師的講授，給學(xué)生一種茅塞頓開(kāi)的感覺(jué)。環(huán)節(jié)四 回歸生活 提升情感我將引導(dǎo)學(xué)生閱讀課本，通過(guò)設(shè)置活動(dòng)探究課，結(jié)合生活實(shí)際從時(shí)效，便利，實(shí)效等方面請(qǐng)學(xué)生評(píng)述公民求助或投訴的四種方式的特點(diǎn)和優(yōu)點(diǎn)。在這一過(guò)程中，我還會(huì)用多媒體展示常用的熱線電話，政府網(wǎng)站上有關(guān)信訪、政務(wù)公開(kāi)及其他便民利民的欄目，豐富課堂資源。讓學(xué)生閱讀課本，自行歸納知識(shí)點(diǎn)，有助于培養(yǎng)學(xué)生自主學(xué)習(xí)能力。
人教版高中語(yǔ)文必修3《寡人之于國(guó)也》說(shuō)課稿2篇
（明確：“寡人之于國(guó)也，盡心焉耳矣”，但“寡人之民不加多，何也？”）②他認(rèn)為自己對(duì)國(guó)家政務(wù)盡心盡力了，他有哪些具體做法？（明確：移民移粟）③第2—4節(jié)中孟子是怎樣說(shuō)明梁惠王移民移粟的措施與“鄰國(guó)之政”并無(wú)本質(zhì)區(qū)別的？（明確：孟子不直接回答“民不加多”的問(wèn)題，而是用梁惠王熟悉的“戰(zhàn)”設(shè)喻——設(shè)圈套，誘使對(duì)方在不知不覺(jué)中說(shuō)出“不可，直不百步耳，是亦走也?！保苊献诱J(rèn)為怎樣才能做到“王道之始”？要想“王道之成”還需采取哪些措施？（明確：“不違農(nóng)時(shí)，谷不可勝食也。數(shù)罟不入氵夸池，魚(yú)鱉不可勝食也。斧斤以時(shí)入山林，材木不可勝用也。谷與魚(yú)鱉不可勝食，材木不可勝用五畝之宅，樹(shù)之以桑，五十者可以衣帛矣。雞豚狗彘之畜，無(wú)失其時(shí)，七十者可以食肉矣。百畝之田，勿奪其時(shí)，數(shù)口之家，可以無(wú)饑矣。謹(jǐn)庫(kù)序之教，申之以孝涕之義，頒白者不負(fù)戴于道路矣。）這一小步的目的是想讓學(xué)生通過(guò)這些問(wèn)題的解答，可以進(jìn)一步理清思路，掌握文的大概內(nèi)容。
人教版高中語(yǔ)文必修3《老人與海》說(shuō)課稿2篇
3、重要語(yǔ)句的理解“可是一個(gè)人并不是生來(lái)要給打敗的，你盡可把它消滅掉，可就是打不敗他?！苯馕觯哼@是老人第一次回合之后的內(nèi)心獨(dú)白，也是此小說(shuō)的核心精神，充分體現(xiàn)了老人桑地亞哥的生命理念。整句話可以分為兩部分來(lái)理解，前句告訴我們，人生活在自然與社會(huì)當(dāng)中，必不可少要面臨一些坎坷、磨難，這些磨難、坎坷完全可以造成軀體的消滅、消亡，這是人生命的脆弱性。后句，面對(duì)挫折，只要保持一種樂(lè)觀的精神，擁有一顆堅(jiān)強(qiáng)的心靈，那么，人類執(zhí)著奮斗的精神將永不磨滅。4、象征主義題目是《老人與?！罚砻魃?，小說(shuō)是寫(xiě)一位老人及其在海上的經(jīng)歷，但實(shí)際上，老人的形象極具概括性，他已經(jīng)超越了一個(gè)人的存在，而成為了人生的一種象征。老人桑地亞哥就是“硬漢子”的代表，大海則是生命旅途的象征，鯊魚(yú)則是我們行走中的“強(qiáng)物”，厄運(yùn)的象征。人的一生不可能一帆風(fēng)順，不經(jīng)歷風(fēng)雨，怎能見(jiàn)彩虹，走在人生路途中，不可避免我們都要遇到挫折，被厄運(yùn)所阻撓，只有經(jīng)歷與“鯊魚(yú)”的較量，才能成為強(qiáng)者，唱出最美的歌。
