高中數(shù)學(xué)必修一課件 篇3
一、隨機(jī)事件
主要掌握好(三四五)
(1)事件的三種運(yùn)算：并(和)、交(積)、差;注意差A(yù)-B可以表示成A與B的逆的積。
(2)四種運(yùn)算律：交換律、結(jié)合律、分配律、德莫根律。
(3)事件的五種關(guān)系：包含、相等、互斥(互不相容)、對(duì)立、相互獨(dú)立。
二、概率定義
(1)統(tǒng)計(jì)定義：頻率穩(wěn)定在一個(gè)數(shù)附近，這個(gè)數(shù)稱(chēng)為事件的概率;(2)古典定義：要求樣本空間只有有限個(gè)基本事件，每個(gè)基本事件出現(xiàn)的可能性相等，則事件A所含基本事件個(gè)數(shù)與樣本空間所含基本事件個(gè)數(shù)的比稱(chēng)為事件的古典概率;
(3)幾何概率：樣本空間中的元素有無(wú)窮多個(gè)，每個(gè)元素出現(xiàn)的可能性相等，則可以將樣本空間看成一個(gè)幾何圖形，事件A看成這個(gè)圖形的子集，它的概率通過(guò)子集圖形的大小與樣本空間圖形的大小的比來(lái)計(jì)算;
(4)公理化定義：滿(mǎn)足三條公理的任何從樣本空間的子集集合到[0，1]的映射。
三、概率性質(zhì)與公式
(1)加法公式：P(A+B)=p(A)+P(B)-P(AB)，特別地，如果A與B互不相容，則P(A+B)=P(A)+P(B);
(2)差：P(A-B)=P(A)-P(AB)，特別地，如果B包含于A，則P(A-B)=P(A)-P(B);
(3)乘法公式：P(AB)=P(A)P(B|A)或P(AB)=P(A|B)P(B)，特別地，如果A與B相互獨(dú)立，則P(AB)=P(A)P(B);
(4)全概率公式：P(B)=∑P(Ai)P(B|Ai).它是由因求果，
貝葉斯公式：P(Aj|B)=P(Aj)P(B|Aj)/∑P(Ai)P(B|Ai).它是由果索因;
如果一個(gè)事件B可以在多種情形(原因)A1,A2,....,An下發(fā)生，則用全概率公式求B發(fā)生的概率;如果事件B已經(jīng)發(fā)生，要求它是由Aj引起的概率，則用貝葉斯公式.
(5)二項(xiàng)概率公式：Pn(k)=C(n,k)p^k(1-p)^(n-k),k=0,1,2,....,n.當(dāng)一個(gè)問(wèn)題可以看成n重貝努力試驗(yàn)(三個(gè)條件：n次重復(fù)，每次只有A與A的逆可能發(fā)生，各次試驗(yàn)結(jié)果相互獨(dú)立)時(shí)，要考慮二項(xiàng)概率公式.
高中數(shù)學(xué)學(xué)習(xí)方法總結(jié)
一)、課內(nèi)重視聽(tīng)講，課后及時(shí)復(fù)習(xí)。
新知識(shí)的接受，數(shù)學(xué)能力的培養(yǎng)主要在課堂上進(jìn)行，所以要特點(diǎn)重視課內(nèi)的學(xué)習(xí)效率，尋求正確的學(xué)習(xí)方法。上課時(shí)要緊跟老師的思路，積極展開(kāi)思維預(yù)測(cè)下面的步驟，比較自己的解題思路與教師所講有哪些不同。特別要抓住基礎(chǔ)知識(shí)和基本技能的學(xué)習(xí)，課后要及時(shí)復(fù)習(xí)不留疑點(diǎn)。首先要在做各種習(xí)題之前將老師所講的知識(shí)點(diǎn)回憶一遍，正確掌握各類(lèi)公式的推理過(guò)程，應(yīng)盡量回憶而不采用不清楚立即翻書(shū)之舉。認(rèn)真獨(dú)立完成作業(yè)，勤于思考，從某種意義上講，應(yīng)不造成不懂即問(wèn)的學(xué)習(xí)作風(fēng)，對(duì)于有些題目由于自己的思路不清，一時(shí)難以解出，應(yīng)讓自己冷靜下來(lái)認(rèn)真分析題目，盡量自己解決。在每個(gè)階段的學(xué)習(xí)中要進(jìn)行整理和歸納總結(jié)，把知識(shí)的點(diǎn)、線、面結(jié)合起來(lái)交織成知識(shí)網(wǎng)絡(luò)，納入自己的知識(shí)體系。
二)、適當(dāng)多做題，養(yǎng)成良好的解題習(xí)慣。
要想學(xué)好數(shù)學(xué)，多做題是難免的，熟悉掌握各種題型的解題思路。剛開(kāi)始要從基礎(chǔ)題入手，以課本上的習(xí)題為準(zhǔn)，反復(fù)練習(xí)打好基礎(chǔ)，再找一些課外的習(xí)題，以幫助開(kāi)拓思路，提高自己的分析、解決能力，掌握一般的解題規(guī)律。對(duì)于一些易錯(cuò)題，可備有錯(cuò)題集，寫(xiě)出自己的解題思路和正確的解題過(guò)程兩者一起比較找出自己的錯(cuò)誤所在，以便及時(shí)更正。在平時(shí)要養(yǎng)成良好的解題習(xí)慣。讓自己的精力高度集中，使大腦興奮，思維敏捷，能夠進(jìn)入最佳狀態(tài)，在考試中能運(yùn)用自如。實(shí)踐證明：越到關(guān)鍵時(shí)候，你所表現(xiàn)的解題習(xí)慣與平時(shí)練習(xí)無(wú)異。如果平時(shí)解題時(shí)隨便、粗心、大意等，往往在大考中充分暴露，故在平時(shí)養(yǎng)成良好的解題習(xí)慣是非常重要的。
三)、調(diào)整心態(tài)，正確對(duì)待考試。
首先，應(yīng)把主要精力放在基礎(chǔ)知識(shí)、基本技能、基本方法這三個(gè)方面上，因?yàn)槊看慰荚囌冀^大部分的也是基礎(chǔ)性的題目，而對(duì)于那些難題及綜合性較強(qiáng)的題目作為調(diào)劑，認(rèn)真思考，盡量讓自己理出頭緒，做完題后要總結(jié)歸納。調(diào)整好自己的心態(tài)，使自己在任何時(shí)候鎮(zhèn)靜，思路有條不紊，克服浮躁的情緒。特別是對(duì)自己要有信心，永遠(yuǎn)鼓勵(lì)自己，除了自己，誰(shuí)也不能把我打倒，要有自己不垮，誰(shuí)也不能打垮我的自豪感。
在考試前要做好準(zhǔn)備，練練常規(guī)題，把自己的思路展開(kāi)，切忌考前去在保證正確率的前提下提高解題速度。對(duì)于一些容易的基礎(chǔ)題要有十二分把握拿全分;對(duì)于一些難題，也要盡量拿分，考試中要學(xué)會(huì)嘗試得分，使自己的水平正常甚至超常發(fā)揮。
由此可見(jiàn)，要把數(shù)學(xué)學(xué)好就得找到適合自己的學(xué)習(xí)方法，了解數(shù)學(xué)學(xué)科的特點(diǎn)，使自己進(jìn)入數(shù)學(xué)的廣闊天地中去。
高中數(shù)學(xué)必修一課件 篇4
②應(yīng)用對(duì)數(shù)函數(shù)的性質(zhì)可以解決：對(duì)數(shù)的大小比較，求復(fù)合函數(shù)的定義域、值 域及單調(diào)性。
③ 注重函數(shù)思想、等價(jià)轉(zhuǎn)化、分類(lèi)討論等思想的滲透,提高解題能力。
教學(xué)過(guò)程設(shè)計(jì)：
例 1 比較下列各組數(shù)的大小。
生：可構(gòu)造一個(gè)以a為底的對(duì)數(shù)函數(shù)，用對(duì)數(shù)函數(shù)的單調(diào)性比大小。
調(diào)遞減，所以loga5.1>loga5.9 ;當(dāng)a>1時(shí)，函數(shù)y=logax單調(diào)遞
Ⅱ)當(dāng)a>1時(shí)，函數(shù)y=logax在(0，+∞)上是增函數(shù)，
生：找“中間量”， log0.50.6>0，lnЛ>0，logЛ0.51，
log0.50.6
函數(shù)圖象的位置關(guān)系來(lái)比大小。
2 函數(shù)的定義域, 值 域及單調(diào)性。
例 2 ⑴求函數(shù)y=的定義域。
⑵解不等式log0.2(x2+2x-3)>log0.2(3x+3)
師：如何來(lái)求⑴中函數(shù)的定義域?(提示：求函數(shù)的定義域，就是要使函數(shù)有意義。若函數(shù)中含有分母，分母不為零;有偶次根式，被開(kāi)方式大于或等于零;若函數(shù)中有對(duì)數(shù)的形式，則真數(shù)大于零，如果函數(shù)中同時(shí)出現(xiàn)以上幾種情況，就要全部考慮進(jìn)去，求它們共同作用的結(jié)果。)生：分母2x-1≠0且偶次根式的被開(kāi)方式log0.8x-1≥0，且真數(shù)x>0。
∴x(0,0.5)∪(0.5,0.8〕
分析：要解這個(gè)不等式,首先要使這個(gè)不等式有意義，即真數(shù)大于零，
再根據(jù)對(duì)數(shù)函數(shù)的單調(diào)性求解。
例 3 求下列函數(shù)的值域和單調(diào)區(qū)間。
師：求例3中函數(shù)的的值域和單調(diào)區(qū)間要用及復(fù)合函數(shù)的思想方法。
下面請(qǐng)同學(xué)們來(lái)解⑴。
生：此函數(shù)可看作是由y= log0.5u, u= x- x2復(fù)合而成。
函數(shù)y=log0.5(x- x2)的單調(diào)遞減區(qū)間(0,0.5]，單調(diào)遞 增區(qū)間[0.5,1)
函數(shù)都不存在，性質(zhì)就無(wú)從談起。
通過(guò)這堂課使同學(xué)們對(duì)等價(jià)轉(zhuǎn)化、分類(lèi)討論等思想加以應(yīng)用，提高解題能力。
①lg(x2-3x-4)≥lg(2x+10);②loga(x2-x)≥loga(x+1),(a為常數(shù))
⑶已知函數(shù)y=loga (a>0, b>0, 且 a≠1)
①求它的定義域;②討論它的奇偶性; ③討論它的單調(diào)性。
⑷已知函數(shù)y=loga(ax-1) (a>0,a≠1),
這節(jié)課是安排為習(xí)題課，主要利用對(duì)數(shù)函數(shù)的性質(zhì)解決一些問(wèn)題，整個(gè)一堂課分兩個(gè)部分：一 .比較數(shù)的大小,想通過(guò)這一部分的練習(xí)，
培養(yǎng)同學(xué)們構(gòu)造函數(shù)的思想和分類(lèi)討論、數(shù)形結(jié)合的思想。二.函數(shù)的定義域, 值 域及單調(diào)性，想通過(guò)這一部分的練習(xí)，能使同學(xué)們重視求函數(shù)的定義域。因?yàn)閷W(xué)生在求函數(shù)的值域和單調(diào)區(qū)間時(shí)，往往不考慮函數(shù)的定義域，并且這種錯(cuò)誤很頑固，不易糾正。因此，力求學(xué)生做到想法正確，步驟清晰。為了調(diào)動(dòng)學(xué)生的積極性，突出學(xué)生是課堂的主體，便把例題分了層次，由易到難，力求做到每題都能由學(xué)生獨(dú)立完成。但是，每一道題的解題過(guò)程，老師都應(yīng)該給以板書(shū)，這樣既讓學(xué)生有了獲取新知識(shí)的快樂(lè)，又不必為了解題格式的不熟悉而煩惱。每一題講完后，由教師簡(jiǎn)明扼要地小結(jié)，以使好學(xué)生掌握地更完善，較差的學(xué)生也能夠跟上。

當(dāng)今世界經(jīng)濟(jì)發(fā)展有兩個(gè)明顯的趨勢(shì)：一是世界經(jīng)濟(jì)區(qū)域集團(tuán)化，二是世界經(jīng)濟(jì)全球化。世界經(jīng)濟(jì)區(qū)域集團(tuán)化是最終實(shí)現(xiàn)經(jīng)濟(jì)全球化的重要步驟和途徑，經(jīng)濟(jì)全球化則是區(qū)域經(jīng)濟(jì)集團(tuán)化的最終歸宿。
世界經(jīng)濟(jì)區(qū)域集團(tuán)化是生產(chǎn)力高度發(fā)展的必然產(chǎn)物，是生產(chǎn)國(guó)家化、國(guó)際分工向縱深發(fā)展需要加強(qiáng)合作的結(jié)果，也是世界經(jīng)濟(jì)競(jìng)爭(zhēng)激烈的表現(xiàn)。它產(chǎn)生的原因有：現(xiàn)代科技的發(fā)展、國(guó)際間經(jīng)濟(jì)競(jìng)爭(zhēng)和客觀上存在的分工。區(qū)域集團(tuán)化的發(fā)展分為三個(gè)階段：第一階段為五六十年代，世界經(jīng)濟(jì)集團(tuán)化的趨勢(shì)主要出現(xiàn)在歐洲，如歐洲煤炭共同體的出現(xiàn)。第二階段為六七十年代，區(qū)域集團(tuán)化成為一種世界經(jīng)濟(jì)現(xiàn)象。歐洲區(qū)域集團(tuán)化趨勢(shì)進(jìn)一步發(fā)展，如歐共體的建立；一些發(fā)展中國(guó)家的地區(qū)性經(jīng)濟(jì)集團(tuán)也紛紛出現(xiàn)，如東盟的出現(xiàn)。第三階段為80年代至今，區(qū)域集團(tuán)化掀起新的浪潮，進(jìn)入了較高層次的經(jīng)濟(jì)一體化時(shí)期，出現(xiàn)了歐盟、北美自由貿(mào)易區(qū)和亞太經(jīng)合組織三大區(qū)域經(jīng)濟(jì)集團(tuán)。
世界經(jīng)濟(jì)全球化是世界生產(chǎn)力發(fā)展的要求和結(jié)果，是不以人的意志為轉(zhuǎn)移的歷史趨勢(shì)。它突出的表現(xiàn)在國(guó)際貿(mào)易、國(guó)際投資、國(guó)際金融和跨國(guó)公司的發(fā)展。經(jīng)濟(jì)全球化的過(guò)程中的問(wèn)題是：在經(jīng)濟(jì)全球化的過(guò)程中，不可避免地把資本主義固有的矛盾擴(kuò)展到全球，造成南北矛盾、貧富分化、環(huán)境問(wèn)題、能源危機(jī)、全球性的經(jīng)濟(jì)金融危機(jī)、恐怖組織活動(dòng)猖獗等等，直接影響到人類(lèi)的生存與發(fā)展。
我國(guó)在當(dāng)今世界經(jīng)濟(jì)發(fā)展趨勢(shì)中，作為發(fā)展中國(guó)家，應(yīng)該如何面對(duì)機(jī)遇和挑戰(zhàn)，成了新時(shí)期經(jīng)濟(jì)發(fā)展人們共同關(guān)心的話題。從中國(guó)加入亞太經(jīng)合組織、加入世界貿(mào)易組織，加強(qiáng)同東盟的聯(lián)系的史實(shí)中，我們的態(tài)度是：在堅(jiān)持獨(dú)立自主、自力更生的前提下，擁有“雙贏”的思維，抱著開(kāi)放的心態(tài)，加強(qiáng)國(guó)際的合作與交流，參與國(guó)際競(jìng)爭(zhēng)，抓住機(jī)遇，接受挑戰(zhàn)，在國(guó)際的競(jìng)爭(zhēng)和合作中，提高我國(guó)的經(jīng)濟(jì)發(fā)展水平，跟隨世界發(fā)展的潮流。概括而言，就是辯證地看待世界經(jīng)濟(jì)發(fā)展趨勢(shì)這一經(jīng)濟(jì)現(xiàn)象，樹(shù)立正確的.發(fā)展觀。
課標(biāo)要求：以歐洲聯(lián)盟、北美自由貿(mào)易區(qū)及亞太經(jīng)濟(jì)合作組織為例，認(rèn)識(shí)當(dāng)今世界經(jīng)濟(jì)區(qū)域集團(tuán)化發(fā)展趨勢(shì)。
教學(xué)目標(biāo)：
(1)知識(shí)與能力：分析第二次世界大戰(zhàn)后西歐經(jīng)濟(jì)進(jìn)入“黃金時(shí)代”的原因；簡(jiǎn)述歐洲國(guó)家從“歐共體”走向歐盟的歷程,認(rèn)識(shí)歐洲聯(lián)盟成立對(duì)世界經(jīng)濟(jì)和政治格局的影響。

(3)情感、態(tài)度與價(jià)值觀：通過(guò)對(duì)歐洲走向聯(lián)合這段歷史的學(xué)習(xí)，認(rèn)識(shí)當(dāng)今國(guó)際社會(huì)國(guó)家間團(tuán)結(jié)協(xié)作的重要性，樹(shù)立國(guó)際意識(shí)；通過(guò)對(duì)歐洲走向聯(lián)合的史實(shí)的歸納，得出一個(gè)別國(guó)家或地區(qū)怎樣才能快速發(fā)展的一般規(guī)律；并結(jié)合我國(guó)的實(shí)際，進(jìn)一步探討一下我們可以借鑒哪些做法，從而樹(shù)立為我國(guó)社會(huì)主義現(xiàn)代化建設(shè)而奮斗的責(zé)任感。
教學(xué)建議：
1、本課共有三個(gè)方面的內(nèi)容，“西歐經(jīng)濟(jì)的'黃金時(shí)代'”主要講述：二戰(zhàn)后的20世紀(jì)50年代到60年代，西歐各國(guó)經(jīng)濟(jì)在恢復(fù)的基礎(chǔ)上，進(jìn)入調(diào)整增長(zhǎng)期,被稱(chēng)為西歐經(jīng)濟(jì)的“黃金時(shí)代”；“從'歐共體到'歐洲聯(lián)盟'”主要是歐洲從經(jīng)濟(jì)一體化到政治一體化的發(fā)展趨勢(shì)；“貨幣王國(guó)的世界公民”主要以歐元的流通為例，進(jìn)一步表明歐洲走向聯(lián)合的趨勢(shì)。
2、西歐經(jīng)濟(jì)高速發(fā)展的共同原因：第一，西歐各國(guó)進(jìn)行社會(huì)改革和政策調(diào)整。進(jìn)行社會(huì)改革，例如：推行福利制度，適當(dāng)改善人民的生活條件，緩和社會(huì)矛盾，穩(wěn)定社會(huì)秩序；進(jìn)行政策調(diào)整，如：將一些私人壟斷企業(yè)國(guó)有化，并建立有關(guān)國(guó)計(jì)民生的重要工業(yè)部門(mén)。這些政策的推行，促進(jìn)了西歐經(jīng)濟(jì)的穩(wěn)定持續(xù)高速發(fā)展，從而出現(xiàn)前所未有的繁榮。第二，馬歇爾計(jì)劃的實(shí)施，解決了西歐戰(zhàn)后經(jīng)濟(jì)發(fā)展的啟動(dòng)資金，西歐重工業(yè)在短時(shí)期內(nèi)完成了新的裝備，并有能力購(gòu)買(mǎi)足夠的工業(yè)原料。第三，戰(zhàn)后西歐廣泛使用第三次科技革命的成果，并對(duì)產(chǎn)業(yè)部門(mén)進(jìn)行了改造，使勞動(dòng)生產(chǎn)率大大提高，從而有力地推動(dòng)了經(jīng)濟(jì)的高速發(fā)展。
3、伴隨著歐洲經(jīng)濟(jì)合作的成功，歐洲經(jīng)濟(jì)不斷的恢復(fù)，要求在國(guó)際上發(fā)揮更重要的作用。因而要加強(qiáng)在政治領(lǐng)域的合作成為歐洲各國(guó)的一致要求。面對(duì)二戰(zhàn)結(jié)束后以美蘇為首的兩極爭(zhēng)霸的冷戰(zhàn)格局，歐洲各國(guó)迫切要求組成一個(gè)更加強(qiáng)大的團(tuán)體來(lái)維護(hù)自己的利益。于是在政治領(lǐng)域的合作很快便實(shí)施開(kāi)來(lái)。
4、為進(jìn)一步加強(qiáng)歐洲共同體之間的經(jīng)濟(jì)合作與交流，減少共同體內(nèi)部成員國(guó)存在的貿(mào)易壁壘，用統(tǒng)一的貨幣在歐共體各國(guó)之間流通，實(shí)現(xiàn)經(jīng)濟(jì)的聯(lián)合，從而進(jìn)一步加強(qiáng)歐洲各國(guó)之間的政治合作。
課標(biāo)要求：以歐洲聯(lián)盟、北美自由貿(mào)易區(qū)及亞太經(jīng)濟(jì)合作組織為例，認(rèn)識(shí)當(dāng)今世界經(jīng)濟(jì)區(qū)域集團(tuán)化發(fā)展趨勢(shì)。
教學(xué)目標(biāo)：
(1)知識(shí)與能力：了解東盟的發(fā)展歷程，說(shuō)說(shuō)中國(guó)與東盟的交往情況；分析北美自由貿(mào)易區(qū)建立的原因和影響，比較北美自由貿(mào)易區(qū)與歐盟的異同；概述亞太經(jīng)濟(jì)合作組織建立的過(guò)程，探討亞太國(guó)家加強(qiáng)合作的途徑與方式。
(2)過(guò)程與方法：通過(guò)搜集中國(guó)與東盟交往的材料，了解東盟日益擴(kuò)大及其影響；用列表等方式比較北美自由貿(mào)易區(qū)與歐盟的異同，學(xué)習(xí)用比較的方法認(rèn)識(shí)歷史問(wèn)題；通過(guò)上網(wǎng)等途徑搜集中國(guó)參加APEC會(huì)議的資料，多渠道去了解和認(rèn)識(shí)APEC建立的史實(shí)及影響。
(3)情感、態(tài)度與價(jià)值觀：通過(guò)對(duì)東盟、北美自由貿(mào)易區(qū)和亞太經(jīng)合組織等區(qū)域經(jīng)濟(jì)一體化進(jìn)程的學(xué)習(xí)和了解，體會(huì)當(dāng)今世界國(guó)家間加強(qiáng)合作、競(jìng)爭(zhēng)與發(fā)展的重要性，樹(shù)立合作與競(jìng)爭(zhēng)的意識(shí)。
重點(diǎn)難點(diǎn)：
重點(diǎn)：通過(guò)了解歐洲聯(lián)盟、北美自由貿(mào)易區(qū)及亞太經(jīng)濟(jì)合作組織，認(rèn)識(shí)當(dāng)今世界經(jīng)濟(jì)區(qū)域集團(tuán)化發(fā)展趨勢(shì)。
教學(xué)建議：
1、在經(jīng)濟(jì)全球化的進(jìn)程中，亞太地區(qū)的經(jīng)濟(jì)集團(tuán)化也在不斷深入發(fā)展。世界三大區(qū)域性經(jīng)濟(jì)集團(tuán)有兩個(gè)分別在該地區(qū)。這一地區(qū)成為當(dāng)今世界上經(jīng)濟(jì)發(fā)展最活躍地區(qū)。課文分別以“東盟”、“北美自由貿(mào)易區(qū)”和“亞太經(jīng)全組織”三個(gè)經(jīng)濟(jì)區(qū)域集團(tuán)為例，介紹了當(dāng)今世界經(jīng)濟(jì)區(qū)域集團(tuán)化發(fā)展趨勢(shì)。每個(gè)集團(tuán)內(nèi)部有著自身的規(guī)則的同時(shí)也不斷與其它區(qū)域集團(tuán)相聯(lián)系，從而使世界經(jīng)濟(jì)形成了密不可分的一個(gè)整體。
2、東南亞國(guó)家聯(lián)盟自1967成立以來(lái)，已經(jīng)歷時(shí)近三分之一世紀(jì)。東盟在維護(hù)和促進(jìn)各成員國(guó)相互間的政治和經(jīng)濟(jì)合作,實(shí)現(xiàn)地區(qū)和平穩(wěn)定,加快成員國(guó)經(jīng)濟(jì)增長(zhǎng),提高成員國(guó)人民生活水平等方面都取得了顯著成績(jī)。尤其是在國(guó)際政治方面，極大地增強(qiáng)了東盟的國(guó)際地位。東盟在由四大洲國(guó)家組成的APEC中具有舉足輕重的政治地位，又是由亞歐兩大洲主要國(guó)家參加的亞歐會(huì)議的倡議者和發(fā)起者,在東亞乃至亞洲政治舞臺(tái)上成為使日本、中國(guó)和印度等大國(guó)瞠乎其后的主角。
3、日本經(jīng)濟(jì)的崛起，特別是歐洲經(jīng)濟(jì)一體化實(shí)施的外在壓力，美國(guó)、加拿大和墨西哥3國(guó)發(fā)展各自經(jīng)濟(jì)的內(nèi)在動(dòng)力，是北美自由貿(mào)易區(qū)成立的根本原因。美、加、墨3國(guó)又是山水相連的鄰邦；語(yǔ)言文字、價(jià)值觀念、風(fēng)俗習(xí)慣等又頗相似；經(jīng)濟(jì)互補(bǔ)性強(qiáng)；相互貿(mào)易基礎(chǔ)良好，美、加、墨3國(guó)具有實(shí)行經(jīng)濟(jì)一體化的必要性，又具有實(shí)行經(jīng)濟(jì)一體化的可能性。美國(guó)認(rèn)為要取得世界經(jīng)濟(jì)的主導(dǎo)地位，只有建立以自己為中心經(jīng)濟(jì)區(qū)域集團(tuán)，才能在經(jīng)濟(jì)全球化大潮中立于不敗之地。
4、二十世紀(jì)七十年代后，亞太地區(qū)，特別是東亞各國(guó)和地區(qū)的對(duì)外開(kāi)放經(jīng)濟(jì)政策和經(jīng)濟(jì)迅速發(fā)展為亞太區(qū)域經(jīng)濟(jì)合作創(chuàng)造了條件。東亞地區(qū)經(jīng)濟(jì)的發(fā)展，國(guó)際收支條件的改善，緩解亞太地區(qū)南北之間的矛盾，為亞太經(jīng)濟(jì)合作創(chuàng)造了條件。歐共體統(tǒng)一市場(chǎng)和美加自由貿(mào)易區(qū)的建立，刺激了亞太向區(qū)域經(jīng)濟(jì)合作的方向發(fā)展。亞太經(jīng)合組織的主要活動(dòng),為各成員提供區(qū)域經(jīng)濟(jì),科技,貿(mào)易和發(fā)展等方面多邊合作的機(jī)會(huì),交流各成員在這些領(lǐng)域內(nèi)的經(jīng)驗(yàn),促進(jìn)本區(qū)域的共同發(fā)展.它從產(chǎn)生、發(fā)展及運(yùn)作模式均區(qū)別于歐盟和NAFTA，有自身的特點(diǎn)，這些特點(diǎn)適應(yīng)了APEC各成員國(guó)經(jīng)濟(jì)發(fā)展的狀況和經(jīng)濟(jì)運(yùn)行模式。
課標(biāo)要求：
(1)以“布雷頓森林體系”建立為例，認(rèn)識(shí)第二次世界大戰(zhàn)后以美國(guó)為主導(dǎo)的資本主義世界經(jīng)濟(jì)體系的形成。
(2)了解世界貿(mào)易組織(WTO)的由來(lái)和發(fā)展，認(rèn)識(shí)它在世界經(jīng)濟(jì)全球化進(jìn)程中的作用。了解中國(guó)參加世界貿(mào)易組織(WTO)的史實(shí)，認(rèn)識(shí)其影響和作用。
(3)了解經(jīng)濟(jì)全球化的發(fā)展趨勢(shì)，探討經(jīng)濟(jì)全球化進(jìn)程中的問(wèn)題。
教學(xué)目標(biāo)：
(1)知識(shí)與能力：了解“布雷頓森林體系”建立的基本史實(shí)，分析其影響；簡(jiǎn)述世界貿(mào)易組織(WTO)的由來(lái)和發(fā)展，認(rèn)識(shí)它在世界經(jīng)濟(jì)全球化進(jìn)程中的作用；了解中國(guó)參加世界貿(mào)易組織(WTO)的史實(shí)，認(rèn)識(shí)其影響和作用；概述經(jīng)濟(jì)全球化的發(fā)展趨勢(shì)，探討經(jīng)濟(jì)全球化進(jìn)程中的問(wèn)題。
(2)過(guò)程與方法：閱讀課文和查找中國(guó)加入世貿(mào)組織談判的歷程等，了解“從GATT到WTO”的過(guò)程，圍繞世界貿(mào)易組織建立的必要性并對(duì)中國(guó)加入WTO的利與弊等問(wèn)題展開(kāi)討論；開(kāi)展課堂討論或辯論：經(jīng)濟(jì)全球化對(duì)本地區(qū)的影響是利大于弊還是弊大于利?如何解決經(jīng)濟(jì)全球化出現(xiàn)的問(wèn)題?從多角度去分析歷史問(wèn)題。
(3)情感、態(tài)度與價(jià)值觀：通過(guò)了解經(jīng)濟(jì)全球化與中國(guó)加入世界貿(mào)易組織帶來(lái)的機(jī)遇與挑戰(zhàn)，樹(shù)立面向世界、積極參與國(guó)際合作與競(jìng)爭(zhēng)、促進(jìn)世界和平與發(fā)展的信念和為我國(guó)社會(huì)主義現(xiàn)代化建設(shè)而奮斗的責(zé)任感；通過(guò)了解經(jīng)濟(jì)區(qū)域集團(tuán)化與世界經(jīng)濟(jì)全球化之間的相互關(guān)系，認(rèn)識(shí)現(xiàn)實(shí)生活中合作

Have you ever been to Tibet? Do you want to travel in Tibet? Can you tell me something about Tibet?
Tibet lies on the Qinghai-Tibet Plateau of the southwest border of China. The average height of the whole region is more than 4,000 meters above sea level, for which Tibet is known as “Roof of the World”. The highest peak of Tibet, also the highest in Himalayas and in the whole world, is Everest Peak, which is as high as 8,846.27 meters above sea level.
Although a part of China, Tibet has a unique culture of all its own. It is mainly inhabited by Tibetans, a minority nationality of old and mysterious people. Tourist attractions include the Potala Palace in Lhasa, Jokhang Temple, and a number of Buddhist sacred places.
Tibet (Xi Zang in Chinese) is to the south of Xin Jiang Uygur Autonomous Region and Qing Hai Province, to the west of Sichuan, to the northwest of Yunnan and to the north of India and Nepal. Its population of 2.3 million people come from a variety of ethnic groups including Tibetan, Han, Monba and Lhota. Its capital city is Lhasa. Northwest Tibet, mainly Qing Hai plateau, is home to a variety of unusual and unique animals. Across the northern expanse of Tibet, you can see vast grasslands where horses, yak and sheep roam freely. The world's lowest valley, the Grand Yarlun-tzanpo River Valley lies in east Tibet. It is freezing cold in most time of the year. Most tourists come to visit Tibet only in the warmest seasons, June, July, August and early September.
We know Wang Wei and Wang Kun have traveled down the Mekong. Today they have reached the Tibetan Mountains. They will stay there for a night. Now let’s look at the passage “A night in the mountains” on page 22. Read it quickly to find the main idea. Show some questions.
1.How does Wang Kun feel about the trip now?
2.What do you think has changed his attitude?
3.Is it natural for Wang Kun not to feel lonely?
4.Would you feel the same way in this situation? Why or Why not?
Let the students listen to the recorder and mark the rising and falling tone of each sense group and sentence. Then practice reading aloud. Pay attention to pronunciation and intonation.
Suppose Wang Wei and Wang Kun leave their camp the next morning and go on with the journey. Make a short dialogue between them.
Sample dialogue :
--Oh , up so early?
--Early? It’s nearly 9 o’clock.
--Oops! (Look at his watch). I guess you’re right.
--Why were you so tired?
--Well, I stayed up late last night to watch the stars.
--That’s nice. They must be pretty.
--Yes, they are.
Then ask students to make up their own dialogues. They may discuss and practice in pairs.
In this unit, we have read the first two parts of a travel journal and have listened to the third part of the travel journal. What is the difference between a journal and a diary? Let’s read the passage on page 23 and find out the difference between the two.
Now let’s do a writing practice. Imagine that you are a friend of Wang Wei. Write a short letter to her and ask her to describe: how she feels, what she is doing, and some place you want to know about. Then wish her well on her journey by using at least two of these expressions:
Have a nice/good time. Have a nice/good trip. Take care.
Good luck on your journey. Say “Hello” to …. Write to me.
Give my best/love wishes to …. Have fun.
Tell the students that they can refer to the following steps.
In pairs. Choose the details from the journey that are most interesting. Think of what else you would like to know about the journey. Write these ideas down as questions.
Now choose two or three of the best questions for your letter. Each question should have another sentence explaining why you want to know this information.
Put them in an order that makes sense.
Begin your letter as shown in the textbook and add your questions for Wang Wei.
Finish your letter as shown in the textbook.
A sample writing:
Hi, brave little Wei,
How I worry about you and Wang Kun! Do you have a good time now? I hope so. What are you doing now? Are you still in Laos? Can you tell me something about people’s life there? When are you leaving for Cambodia? When you get there, tell me about the Buddhist temples there. Please send some photos with your next letter! Well, Have a good trip and don’t forget to write to me! Give my best wishes to Wang Kun. Good luck on your journey.
Take care!

要想學(xué)好數(shù)學(xué)，多做題是難免的，熟悉掌握各種題型的解題思路。剛開(kāi)始要從基礎(chǔ)題入手，以課本上的習(xí)題為準(zhǔn)，反復(fù)練習(xí)打好基礎(chǔ)，再找一些課外的習(xí)題，以幫助開(kāi)拓思路，提高自己的分析、解決能力，掌握一般的解題規(guī)律。對(duì)于一些易錯(cuò)題，可備有錯(cuò)題集，寫(xiě)出自己的解題思路和正確的解題過(guò)程兩者一起比較找出自己的錯(cuò)誤所在，以便及時(shí)更正。在平時(shí)要養(yǎng)成良好的解題習(xí)慣。讓自己的精力高度集中，使大腦興奮，思維敏捷，能夠進(jìn)入最佳狀態(tài)，在考試中能運(yùn)用自如。實(shí)踐證明：越到關(guān)鍵時(shí)候，你所表現(xiàn)的解題習(xí)慣與平時(shí)練習(xí)無(wú)異。如果平時(shí)解題時(shí)隨便、粗心、大意等，往往在大考中充分暴露，故在平時(shí)養(yǎng)成良好的解題習(xí)慣是非常重要的。
三)、調(diào)整心態(tài)，正確對(duì)待考試。
首先，應(yīng)把主要精力放在基礎(chǔ)知識(shí)、基本技能、基本方法這三個(gè)方面上，因?yàn)槊看慰荚囌冀^大部分的也是基礎(chǔ)性的題目，而對(duì)于那些難題及綜合性較強(qiáng)的題目作為調(diào)劑，認(rèn)真思考，盡量讓自己理出頭緒，做完題后要總結(jié)歸納。調(diào)整好自己的心態(tài)，使自己在任何時(shí)候鎮(zhèn)靜，思路有條不紊，克服浮躁的情緒。特別是對(duì)自己要有信心，永遠(yuǎn)鼓勵(lì)自己，除了自己，誰(shuí)也不能把我打倒，要有自己不垮，誰(shuí)也不能打垮我的自豪感。
在考試前要做好準(zhǔn)備，練練常規(guī)題，把自己的思路展開(kāi)，切忌考前去在保證正確率的前提下提高解題速度。對(duì)于一些容易的基礎(chǔ)題要有十二分把握拿全分;對(duì)于一些難題，也要盡量拿分，考試中要學(xué)會(huì)嘗試得分，使自己的水平正常甚至超常發(fā)揮。
由此可見(jiàn)，要把數(shù)學(xué)學(xué)好就得找到適合自己的學(xué)習(xí)方法，了解數(shù)學(xué)學(xué)科的特點(diǎn)，使自己進(jìn)入數(shù)學(xué)的廣闊天地中去。

高中數(shù)學(xué)必修一課件 篇3
一、隨機(jī)事件
主要掌握好(三四五)
(1)事件的三種運(yùn)算：并(和)、交(積)、差;注意差A(yù)-B可以表示成A與B的逆的積。
(2)四種運(yùn)算律：交換律、結(jié)合律、分配律、德莫根律。
(3)事件的五種關(guān)系：包含、相等、互斥(互不相容)、對(duì)立、相互獨(dú)立。
二、概率定義
(1)統(tǒng)計(jì)定義：頻率穩(wěn)定在一個(gè)數(shù)附近，這個(gè)數(shù)稱(chēng)為事件的概率;(2)古典定義：要求樣本空間只有有限個(gè)基本事件，每個(gè)基本事件出現(xiàn)的可能性相等，則事件A所含基本事件個(gè)數(shù)與樣本空間所含基本事件個(gè)數(shù)的比稱(chēng)為事件的古典概率;
(3)幾何概率：樣本空間中的元素有無(wú)窮多個(gè)，每個(gè)元素出現(xiàn)的可能性相等，則可以將樣本空間看成一個(gè)幾何圖形，事件A看成這個(gè)圖形的子集，它的概率通過(guò)子集圖形的大小與樣本空間圖形的大小的比來(lái)計(jì)算;

三、概率性質(zhì)與公式
(1)加法公式：P(A+B)=p(A)+P(B)-P(AB)，特別地，如果A與B互不相容，則P(A+B)=P(A)+P(B);
(2)差：P(A-B)=P(A)-P(AB)，特別地，如果B包含于A，則P(A-B)=P(A)-P(B);
(3)乘法公式：P(AB)=P(A)P(B|A)或P(AB)=P(A|B)P(B)，特別地，如果A與B相互獨(dú)立，則P(AB)=P(A)P(B);
(4)全概率公式：P(B)=∑P(Ai)P(B|Ai).它是由因求果，
貝葉斯公式：P(Aj|B)=P(Aj)P(B|Aj)/∑P(Ai)P(B|Ai).它是由果索因;
如果一個(gè)事件B可以在多種情形(原因)A1,A2,....,An下發(fā)生，則用全概率公式求B發(fā)生的概率;如果事件B已經(jīng)發(fā)生，要求它是由Aj引起的概率，則用貝葉斯公式.

高中數(shù)學(xué)學(xué)習(xí)方法總結(jié)
一)、課內(nèi)重視聽(tīng)講，課后及時(shí)復(fù)習(xí)。
新知識(shí)的接受，數(shù)學(xué)能力的培養(yǎng)主要在課堂上進(jìn)行，所以要特點(diǎn)重視課內(nèi)的學(xué)習(xí)效率，尋求正確的學(xué)習(xí)方法。上課時(shí)要緊跟老師的思路，積極展開(kāi)思維預(yù)測(cè)下面的步驟，比較自己的解題思路與教師所講有哪些不同。特別要抓住基礎(chǔ)知識(shí)和基本技能的學(xué)習(xí)，課后要及時(shí)復(fù)習(xí)不留疑點(diǎn)。首先要在做各種習(xí)題之前將老師所講的知識(shí)點(diǎn)回憶一遍，正確掌握各類(lèi)公式的推理過(guò)程，應(yīng)盡量回憶而不采用不清楚立即翻書(shū)之舉。認(rèn)真獨(dú)立完成作業(yè)，勤于思考，從某種意義上講，應(yīng)不造成不懂即問(wèn)的學(xué)習(xí)作風(fēng)，對(duì)于有些題目由于自己的思路不清，一時(shí)難以解出，應(yīng)讓自己冷靜下來(lái)認(rèn)真分析題目，盡量自己解決。在每個(gè)階段的學(xué)習(xí)中要進(jìn)行整理和歸納總結(jié)，把知識(shí)的點(diǎn)、線、面結(jié)合起來(lái)交織成知識(shí)網(wǎng)絡(luò)，納入自己的知識(shí)體系。
二)、適當(dāng)多做題，養(yǎng)成良好的解題習(xí)慣。
要想學(xué)好數(shù)學(xué)，多做題是難免的，熟悉掌握各種題型的解題思路。剛開(kāi)始要從基礎(chǔ)題入手，以課本上的習(xí)題為準(zhǔn)，反復(fù)練習(xí)打好基礎(chǔ)，再找一些課外的習(xí)題，以幫助開(kāi)拓思路，提高自己的分析、解決能力，掌握一般的解題規(guī)律。對(duì)于一些易錯(cuò)題，可備有錯(cuò)題集，寫(xiě)出自己的解題思路和正確的解題過(guò)程兩者一起比較找出自己的錯(cuò)誤所在，以便及時(shí)更正。在平時(shí)要養(yǎng)成良好的解題習(xí)慣。讓自己的精力高度集中，使大腦興奮，思維敏捷，能夠進(jìn)入最佳狀態(tài)，在考試中能運(yùn)用自如。實(shí)踐證明：越到關(guān)鍵時(shí)候，你所表現(xiàn)的解題習(xí)慣與平時(shí)練習(xí)無(wú)異。如果平時(shí)解題時(shí)隨便、粗心、大意等，往往在大考中充分暴露，故在平時(shí)養(yǎng)成良好的解題習(xí)慣是非常重要的。
三)、調(diào)整心態(tài)，正確對(duì)待考試。
首先，應(yīng)把主要精力放在基礎(chǔ)知識(shí)、基本技能、基本方法這三個(gè)方面上，因?yàn)槊看慰荚囌冀^大部分的也是基礎(chǔ)性的題目，而對(duì)于那些難題及綜合性較強(qiáng)的題目作為調(diào)劑，認(rèn)真思考，盡量讓自己理出頭緒，做完題后要總結(jié)歸納。調(diào)整好自己的心態(tài)，使自己在任何時(shí)候鎮(zhèn)靜，思路有條不紊，克服浮躁的情緒。特別是對(duì)自己要有信心，永遠(yuǎn)鼓勵(lì)自己，除了自己，誰(shuí)也不能把我打倒，要有自己不垮，誰(shuí)也不能打垮我的自豪感。
在考試前要做好準(zhǔn)備，練練常規(guī)題，把自己的思路展開(kāi)，切忌考前去在保證正確率的前提下提高解題速度。對(duì)于一些容易的基礎(chǔ)題要有十二分把握拿全分;對(duì)于一些難題，也要盡量拿分，考試中要學(xué)會(huì)嘗試得分，使自己的水平正常甚至超常發(fā)揮。
由此可見(jiàn)，要把數(shù)學(xué)學(xué)好就得找到適合自己的學(xué)習(xí)方法，了解數(shù)學(xué)學(xué)科的特點(diǎn)，使自己進(jìn)入數(shù)學(xué)的廣闊天地中去。
高中數(shù)學(xué)必修一課件 篇4
②應(yīng)用對(duì)數(shù)函數(shù)的性質(zhì)可以解決：對(duì)數(shù)的大小比較，求復(fù)合函數(shù)的定義域、值 域及單調(diào)性。
③ 注重函數(shù)思想、等價(jià)轉(zhuǎn)化、分類(lèi)討論等思想的滲透,提高解題能力。
教學(xué)過(guò)程設(shè)計(jì)：
例 1 比較下列各組數(shù)的大小。
生：可構(gòu)造一個(gè)以a為底的對(duì)數(shù)函數(shù)，用對(duì)數(shù)函數(shù)的單調(diào)性比大小。
調(diào)遞減，所以loga5.1>loga5.9 ;當(dāng)a>1時(shí)，函數(shù)y=logax單調(diào)遞
Ⅱ)當(dāng)a>1時(shí)，函數(shù)y=logax在(0，+∞)上是增函數(shù)，
生：找“中間量”， log0.50.6>0，lnЛ>0，logЛ0.51，
log0.50.6
函數(shù)圖象的位置關(guān)系來(lái)比大小。
2 函數(shù)的定義域, 值 域及單調(diào)性。
例 2 ⑴求函數(shù)y=的定義域。
⑵解不等式log0.2(x2+2x-3)>log0.2(3x+3)
師：如何來(lái)求⑴中函數(shù)的定義域?(提示：求函數(shù)的定義域，就是要使函數(shù)有意義。若函數(shù)中含有分母，分母不為零;有偶次根式，被開(kāi)方式大于或等于零;若函數(shù)中有對(duì)數(shù)的形式，則真數(shù)大于零，如果函數(shù)中同時(shí)出現(xiàn)以上幾種情況，就要全部考慮進(jìn)去，求它們共同作用的結(jié)果。)生：分母2x-1≠0且偶次根式的被開(kāi)方式log0.8x-1≥0，且真數(shù)x>0。
∴x(0,0.5)∪(0.5,0.8〕
分析：要解這個(gè)不等式,首先要使這個(gè)不等式有意義，即真數(shù)大于零，
再根據(jù)對(duì)數(shù)函數(shù)的單調(diào)性求解。
例 3 求下列函數(shù)的值域和單調(diào)區(qū)間。
師：求例3中函數(shù)的的值域和單調(diào)區(qū)間要用及復(fù)合函數(shù)的思想方法。
下面請(qǐng)同學(xué)們來(lái)解⑴。
生：此函數(shù)可看作是由y= log0.5u, u= x- x2復(fù)合而成。
函數(shù)y=log0.5(x- x2)的單調(diào)遞減區(qū)間(0,0.5]，單調(diào)遞 增區(qū)間[0.5,1)
函數(shù)都不存在，性質(zhì)就無(wú)從談起。
通過(guò)這堂課使同學(xué)們對(duì)等價(jià)轉(zhuǎn)化、分類(lèi)討論等思想加以應(yīng)用，提高解題能力。
①lg(x2-3x-4)≥lg(2x+10);②loga(x2-x)≥loga(x+1),(a為常數(shù))
⑶已知函數(shù)y=loga (a>0, b>0, 且 a≠1)
①求它的定義域;②討論它的奇偶性; ③討論它的單調(diào)性。
⑷已知函數(shù)y=loga(ax-1) (a>0,a≠1),
這節(jié)課是安排為習(xí)題課，主要利用對(duì)數(shù)函數(shù)的性質(zhì)解決一些問(wèn)題，整個(gè)一堂課分兩個(gè)部分：一 .比較數(shù)的大小,想通過(guò)這一部分的練習(xí)，
培養(yǎng)同學(xué)們構(gòu)造函數(shù)的思想和分類(lèi)討論、數(shù)形結(jié)合的思想。二.函數(shù)的定義域, 值 域及單調(diào)性，想通過(guò)這一部分的練習(xí)，能使同學(xué)們重視求函數(shù)的定義域。因?yàn)閷W(xué)生在求函數(shù)的值域和單調(diào)區(qū)間時(shí)，往往不考慮函數(shù)的定義域，并且這種錯(cuò)誤很頑固，不易糾正。因此，力求學(xué)生做到想法正確，步驟清晰。為了調(diào)動(dòng)學(xué)生的積極性，突出學(xué)生是課堂的主體，便把例題分了層次，由易到難，力求做到每題都能由學(xué)生獨(dú)立完成。但是，每一道題的解題過(guò)程，老師都應(yīng)該給以板書(shū)，這樣既讓學(xué)生有了獲取新知識(shí)的快樂(lè)，又不必為了解題格式的不熟悉而煩惱。每一題講完后，由教師簡(jiǎn)明扼要地小結(jié)，以使好學(xué)生掌握地更完善，較差的學(xué)生也能夠跟上。

專(zhuān)題八當(dāng)今世界經(jīng)濟(jì)的全球化趨勢(shì)
通史概要：
當(dāng)今世界經(jīng)濟(jì)發(fā)展有兩個(gè)明顯的趨勢(shì)：一是世界經(jīng)濟(jì)區(qū)域集團(tuán)化，二是世界經(jīng)濟(jì)全球化。世界經(jīng)濟(jì)區(qū)域集團(tuán)化是最終實(shí)現(xiàn)經(jīng)濟(jì)全球化的重要步驟和途徑，經(jīng)濟(jì)全球化則是區(qū)域經(jīng)濟(jì)集團(tuán)化的最終歸宿。
世界經(jīng)濟(jì)區(qū)域集團(tuán)化是生產(chǎn)力高度發(fā)展的必然產(chǎn)物，是生產(chǎn)國(guó)家化、國(guó)際分工向縱深發(fā)展需要加強(qiáng)合作的結(jié)果，也是世界經(jīng)濟(jì)競(jìng)爭(zhēng)激烈的表現(xiàn)。它產(chǎn)生的原因有：現(xiàn)代科技的發(fā)展、國(guó)際間經(jīng)濟(jì)競(jìng)爭(zhēng)和客觀上存在的分工。區(qū)域集團(tuán)化的發(fā)展分為三個(gè)階段：第一階段為五六十年代，世界經(jīng)濟(jì)集團(tuán)化的趨勢(shì)主要出現(xiàn)在歐洲，如歐洲煤炭共同體的出現(xiàn)。第二階段為六七十年代，區(qū)域集團(tuán)化成為一種世界經(jīng)濟(jì)現(xiàn)象。歐洲區(qū)域集團(tuán)化趨勢(shì)進(jìn)一步發(fā)展，如歐共體的建立；一些發(fā)展中國(guó)家的地區(qū)性經(jīng)濟(jì)集團(tuán)也紛紛出現(xiàn)，如東盟的出現(xiàn)。第三階段為80年代至今，區(qū)域集團(tuán)化掀起新的浪潮，進(jìn)入了較高層次的經(jīng)濟(jì)一體化時(shí)期，出現(xiàn)了歐盟、北美自由貿(mào)易區(qū)和亞太經(jīng)合組織三大區(qū)域經(jīng)濟(jì)集團(tuán)。
世界經(jīng)濟(jì)全球化是世界生產(chǎn)力發(fā)展的要求和結(jié)果，是不以人的意志為轉(zhuǎn)移的歷史趨勢(shì)。它突出的表現(xiàn)在國(guó)際貿(mào)易、國(guó)際投資、國(guó)際金融和跨國(guó)公司的發(fā)展。經(jīng)濟(jì)全球化的過(guò)程中的問(wèn)題是：在經(jīng)濟(jì)全球化的過(guò)程中，不可避免地把資本主義固有的矛盾擴(kuò)展到全球，造成南北矛盾、貧富分化、環(huán)境問(wèn)題、能源危機(jī)、全球性的經(jīng)濟(jì)金融危機(jī)、恐怖組織活動(dòng)猖獗等等，直接影響到人類(lèi)的生存與發(fā)展。
我國(guó)在當(dāng)今世界經(jīng)濟(jì)發(fā)展趨勢(shì)中，作為發(fā)展中國(guó)家，應(yīng)該如何面對(duì)機(jī)遇和挑戰(zhàn)，成了新時(shí)期經(jīng)濟(jì)發(fā)展人們共同關(guān)心的話題。從中國(guó)加入亞太經(jīng)合組織、加入世界貿(mào)易組織，加強(qiáng)同東盟的聯(lián)系的史實(shí)中，我們的態(tài)度是：在堅(jiān)持獨(dú)立自主、自力更生的前提下，擁有“雙贏”的思維，抱著開(kāi)放的心態(tài)，加強(qiáng)國(guó)際的合作與交流，參與國(guó)際競(jìng)爭(zhēng)，抓住機(jī)遇，接受挑戰(zhàn)，在國(guó)際的競(jìng)爭(zhēng)和合作中，提高我國(guó)的經(jīng)濟(jì)發(fā)展水平，跟隨世界發(fā)展的潮流。概括而言，就是辯證地看待世界經(jīng)濟(jì)發(fā)展趨勢(shì)這一經(jīng)濟(jì)現(xiàn)象，樹(shù)立正確的.發(fā)展觀。
課標(biāo)要求：以歐洲聯(lián)盟、北美自由貿(mào)易區(qū)及亞太經(jīng)濟(jì)合作組織為例，認(rèn)識(shí)當(dāng)今世界經(jīng)濟(jì)區(qū)域集團(tuán)化發(fā)展趨勢(shì)。
教學(xué)目標(biāo)：
(1)知識(shí)與能力：分析第二次世界大戰(zhàn)后西歐經(jīng)濟(jì)進(jìn)入“黃金時(shí)代”的原因；簡(jiǎn)述歐洲國(guó)家從“歐共體”走向歐盟的歷程,認(rèn)識(shí)歐洲聯(lián)盟成立對(duì)世界經(jīng)濟(jì)和政治格局的影響。
概述歐元產(chǎn)生的影響，培養(yǎng)多角度、多層次理解問(wèn)題的能力。
(2)過(guò)程與方法：通過(guò)討論西歐經(jīng)濟(jì)在二戰(zhàn)后進(jìn)入“黃金時(shí)代”的共同原因，進(jìn)一步思考中國(guó)的社會(huì)主義建設(shè)應(yīng)如何借鑒其合理的方法與正確的經(jīng)驗(yàn)，學(xué)習(xí)用聯(lián)系的方法看待問(wèn)題，提高理論指導(dǎo)實(shí)踐的能力；通過(guò)分組學(xué)習(xí)，搜集“歐共體”及“歐盟”成立的資料，了解整個(gè)歐洲走向聯(lián)合的過(guò)程，認(rèn)識(shí)當(dāng)今世界經(jīng)濟(jì)區(qū)域集團(tuán)化發(fā)展趨勢(shì)。
(3)情感、態(tài)度與價(jià)值觀：通過(guò)對(duì)歐洲走向聯(lián)合這段歷史的學(xué)習(xí)，認(rèn)識(shí)當(dāng)今國(guó)際社會(huì)國(guó)家間團(tuán)結(jié)協(xié)作的重要性，樹(shù)立國(guó)際意識(shí)；通過(guò)對(duì)歐洲走向聯(lián)合的史實(shí)的歸納，得出一個(gè)別國(guó)家或地區(qū)怎樣才能快速發(fā)展的一般規(guī)律；并結(jié)合我國(guó)的實(shí)際，進(jìn)一步探討一下我們可以借鑒哪些做法，從而樹(shù)立為我國(guó)社會(huì)主義現(xiàn)代化建設(shè)而奮斗的責(zé)任感。
教學(xué)建議：
1、本課共有三個(gè)方面的內(nèi)容，“西歐經(jīng)濟(jì)的'黃金時(shí)代'”主要講述：二戰(zhàn)后的20世紀(jì)50年代到60年代，西歐各國(guó)經(jīng)濟(jì)在恢復(fù)的基礎(chǔ)上，進(jìn)入調(diào)整增長(zhǎng)期,被稱(chēng)為西歐經(jīng)濟(jì)的“黃金時(shí)代”；“從'歐共體到'歐洲聯(lián)盟'”主要是歐洲從經(jīng)濟(jì)一體化到政治一體化的發(fā)展趨勢(shì)；“貨幣王國(guó)的世界公民”主要以歐元的流通為例，進(jìn)一步表明歐洲走向聯(lián)合的趨勢(shì)。
2、西歐經(jīng)濟(jì)高速發(fā)展的共同原因：第一，西歐各國(guó)進(jìn)行社會(huì)改革和政策調(diào)整。進(jìn)行社會(huì)改革，例如：推行福利制度，適當(dāng)改善人民的生活條件，緩和社會(huì)矛盾，穩(wěn)定社會(huì)秩序；進(jìn)行政策調(diào)整，如：將一些私人壟斷企業(yè)國(guó)有化，并建立有關(guān)國(guó)計(jì)民生的重要工業(yè)部門(mén)。這些政策的推行，促進(jìn)了西歐經(jīng)濟(jì)的穩(wěn)定持續(xù)高速發(fā)展，從而出現(xiàn)前所未有的繁榮。第二，馬歇爾計(jì)劃的實(shí)施，解決了西歐戰(zhàn)后經(jīng)濟(jì)發(fā)展的啟動(dòng)資金，西歐重工業(yè)在短時(shí)期內(nèi)完成了新的裝備，并有能力購(gòu)買(mǎi)足夠的工業(yè)原料。第三，戰(zhàn)后西歐廣泛使用第三次科技革命的成果，并對(duì)產(chǎn)業(yè)部門(mén)進(jìn)行了改造，使勞動(dòng)生產(chǎn)率大大提高，從而有力地推動(dòng)了經(jīng)濟(jì)的高速發(fā)展。
3、伴隨著歐洲經(jīng)濟(jì)合作的成功，歐洲經(jīng)濟(jì)不斷的恢復(fù)，要求在國(guó)際上發(fā)揮更重要的作用。因而要加強(qiáng)在政治領(lǐng)域的合作成為歐洲各國(guó)的一致要求。面對(duì)二戰(zhàn)結(jié)束后以美蘇為首的兩極爭(zhēng)霸的冷戰(zhàn)格局，歐洲各國(guó)迫切要求組成一個(gè)更加強(qiáng)大的團(tuán)體來(lái)維護(hù)自己的利益。于是在政治領(lǐng)域的合作很快便實(shí)施開(kāi)來(lái)。
4、為進(jìn)一步加強(qiáng)歐洲共同體之間的經(jīng)濟(jì)合作與交流，減少共同體內(nèi)部成員國(guó)存在的貿(mào)易壁壘，用統(tǒng)一的貨幣在歐共體各國(guó)之間流通，實(shí)現(xiàn)經(jīng)濟(jì)的聯(lián)合，從而進(jìn)一步加強(qiáng)歐洲各國(guó)之間的政治合作。
課標(biāo)要求：以歐洲聯(lián)盟、北美自由貿(mào)易區(qū)及亞太經(jīng)濟(jì)合作組織為例，認(rèn)識(shí)當(dāng)今世界經(jīng)濟(jì)區(qū)域集團(tuán)化發(fā)展趨勢(shì)。
教學(xué)目標(biāo)：
(1)知識(shí)與能力：了解東盟的發(fā)展歷程，說(shuō)說(shuō)中國(guó)與東盟的交往情況；分析北美自由貿(mào)易區(qū)建立的原因和影響，比較北美自由貿(mào)易區(qū)與歐盟的異同；概述亞太經(jīng)濟(jì)合作組織建立的過(guò)程，探討亞太國(guó)家加強(qiáng)合作的途徑與方式。
(2)過(guò)程與方法：通過(guò)搜集中國(guó)與東盟交往的材料，了解東盟日益擴(kuò)大及其影響；用列表等方式比較北美自由貿(mào)易區(qū)與歐盟的異同，學(xué)習(xí)用比較的方法認(rèn)識(shí)歷史問(wèn)題；通過(guò)上網(wǎng)等途徑搜集中國(guó)參加APEC會(huì)議的資料，多渠道去了解和認(rèn)識(shí)APEC建立的史實(shí)及影響。
(3)情感、態(tài)度與價(jià)值觀：通過(guò)對(duì)東盟、北美自由貿(mào)易區(qū)和亞太經(jīng)合組織等區(qū)域經(jīng)濟(jì)一體化進(jìn)程的學(xué)習(xí)和了解，體會(huì)當(dāng)今世界國(guó)家間加強(qiáng)合作、競(jìng)爭(zhēng)與發(fā)展的重要性，樹(shù)立合作與競(jìng)爭(zhēng)的意識(shí)。
重點(diǎn)難點(diǎn)：
重點(diǎn)：通過(guò)了解歐洲聯(lián)盟、北美自由貿(mào)易區(qū)及亞太經(jīng)濟(jì)合作組織，認(rèn)識(shí)當(dāng)今世界經(jīng)濟(jì)區(qū)域集團(tuán)化發(fā)展趨勢(shì)。
教學(xué)建議：
1、在經(jīng)濟(jì)全球化的進(jìn)程中，亞太地區(qū)的經(jīng)濟(jì)集團(tuán)化也在不斷深入發(fā)展。世界三大區(qū)域性經(jīng)濟(jì)集團(tuán)有兩個(gè)分別在該地區(qū)。這一地區(qū)成為當(dāng)今世界上經(jīng)濟(jì)發(fā)展最活躍地區(qū)。課文分別以“東盟”、“北美自由貿(mào)易區(qū)”和“亞太經(jīng)全組織”三個(gè)經(jīng)濟(jì)區(qū)域集團(tuán)為例，介紹了當(dāng)今世界經(jīng)濟(jì)區(qū)域集團(tuán)化發(fā)展趨勢(shì)。每個(gè)集團(tuán)內(nèi)部有著自身的規(guī)則的同時(shí)也不斷與其它區(qū)域集團(tuán)相聯(lián)系，從而使世界經(jīng)濟(jì)形成了密不可分的一個(gè)整體。
2、東南亞國(guó)家聯(lián)盟自1967成立以來(lái)，已經(jīng)歷時(shí)近三分之一世紀(jì)。東盟在維護(hù)和促進(jìn)各成員國(guó)相互間的政治和經(jīng)濟(jì)合作,實(shí)現(xiàn)地區(qū)和平穩(wěn)定,加快成員國(guó)經(jīng)濟(jì)增長(zhǎng),提高成員國(guó)人民生活水平等方面都取得了顯著成績(jī)。尤其是在國(guó)際政治方面，極大地增強(qiáng)了東盟的國(guó)際地位。東盟在由四大洲國(guó)家組成的APEC中具有舉足輕重的政治地位，又是由亞歐兩大洲主要國(guó)家參加的亞歐會(huì)議的倡議者和發(fā)起者,在東亞乃至亞洲政治舞臺(tái)上成為使日本、中國(guó)和印度等大國(guó)瞠乎其后的主角。
3、日本經(jīng)濟(jì)的崛起，特別是歐洲經(jīng)濟(jì)一體化實(shí)施的外在壓力，美國(guó)、加拿大和墨西哥3國(guó)發(fā)展各自經(jīng)濟(jì)的內(nèi)在動(dòng)力，是北美自由貿(mào)易區(qū)成立的根本原因。美、加、墨3國(guó)又是山水相連的鄰邦；語(yǔ)言文字、價(jià)值觀念、風(fēng)俗習(xí)慣等又頗相似；經(jīng)濟(jì)互補(bǔ)性強(qiáng)；相互貿(mào)易基礎(chǔ)良好，美、加、墨3國(guó)具有實(shí)行經(jīng)濟(jì)一體化的必要性，又具有實(shí)行經(jīng)濟(jì)一體化的可能性。美國(guó)認(rèn)為要取得世界經(jīng)濟(jì)的主導(dǎo)地位，只有建立以自己為中心經(jīng)濟(jì)區(qū)域集團(tuán)，才能在經(jīng)濟(jì)全球化大潮中立于不敗之地。
4、二十世紀(jì)七十年代后，亞太地區(qū)，特別是東亞各國(guó)和地區(qū)的對(duì)外開(kāi)放經(jīng)濟(jì)政策和經(jīng)濟(jì)迅速發(fā)展為亞太區(qū)域經(jīng)濟(jì)合作創(chuàng)造了條件。東亞地區(qū)經(jīng)濟(jì)的發(fā)展，國(guó)際收支條件的改善，緩解亞太地區(qū)南北之間的矛盾，為亞太經(jīng)濟(jì)合作創(chuàng)造了條件。歐共體統(tǒng)一市場(chǎng)和美加自由貿(mào)易區(qū)的建立，刺激了亞太向區(qū)域經(jīng)濟(jì)合作的方向發(fā)展。亞太經(jīng)合組織的主要活動(dòng),為各成員提供區(qū)域經(jīng)濟(jì),科技,貿(mào)易和發(fā)展等方面多邊合作的機(jī)會(huì),交流各成員在這些領(lǐng)域內(nèi)的經(jīng)驗(yàn),促進(jìn)本區(qū)域的共同發(fā)展.它從產(chǎn)生、發(fā)展及運(yùn)作模式均區(qū)別于歐盟和NAFTA，有自身的特點(diǎn)，這些特點(diǎn)適應(yīng)了APEC各成員國(guó)經(jīng)濟(jì)發(fā)展的狀況和經(jīng)濟(jì)運(yùn)行模式。
課標(biāo)要求：
(1)以“布雷頓森林體系”建立為例，認(rèn)識(shí)第二次世界大戰(zhàn)后以美國(guó)為主導(dǎo)的資本主義世界經(jīng)濟(jì)體系的形成。
(2)了解世界貿(mào)易組織(WTO)的由來(lái)和發(fā)展，認(rèn)識(shí)它在世界經(jīng)濟(jì)全球化進(jìn)程中的作用。了解中國(guó)參加世界貿(mào)易組織(WTO)的史實(shí)，認(rèn)識(shí)其影響和作用。
(3)了解經(jīng)濟(jì)全球化的發(fā)展趨勢(shì)，探討經(jīng)濟(jì)全球化進(jìn)程中的問(wèn)題。

Have you ever been to Tibet? Do you want to travel in Tibet? Can you tell me something about Tibet?
Tibet lies on the Qinghai-Tibet Plateau of the southwest border of China. The average height of the whole region is more than 4,000 meters above sea level, for which Tibet is known as “Roof of the World”. The highest peak of Tibet, also the highest in Himalayas and in the whole world, is Everest Peak, which is as high as 8,846.27 meters above sea level.
Although a part of China, Tibet has a unique culture of all its own. It is mainly inhabited by Tibetans, a minority nationality of old and mysterious people. Tourist attractions include the Potala Palace in Lhasa, Jokhang Temple, and a number of Buddhist sacred places.
Tibet (Xi Zang in Chinese) is to the south of Xin Jiang Uygur Autonomous Region and Qing Hai Province, to the west of Sichuan, to the northwest of Yunnan and to the north of India and Nepal. Its population of 2.3 million people come from a variety of ethnic groups including Tibetan, Han, Monba and Lhota. Its capital city is Lhasa. Northwest Tibet, mainly Qing Hai plateau, is home to a variety of unusual and unique animals. Across the northern expanse of Tibet, you can see vast grasslands where horses, yak and sheep roam freely. The world's lowest valley, the Grand Yarlun-tzanpo River Valley lies in east Tibet. It is freezing cold in most time of the year. Most tourists come to visit Tibet only in the warmest seasons, June, July, August and early September.
We know Wang Wei and Wang Kun have traveled down the Mekong. Today they have reached the Tibetan Mountains. They will stay there for a night. Now let’s look at the passage “A night in the mountains” on page 22. Read it quickly to find the main idea. Show some questions.
1.How does Wang Kun feel about the trip now?
2.What do you think has changed his attitude?
3.Is it natural for Wang Kun not to feel lonely?
4.Would you feel the same way in this situation? Why or Why not?
Let the students listen to the recorder and mark the rising and falling tone of each sense group and sentence. Then practice reading aloud. Pay attention to pronunciation and intonation.
Suppose Wang Wei and Wang Kun leave their camp the next morning and go on with the journey. Make a short dialogue between them.
Sample dialogue :
--Oh , up so early?
--Early? It’s nearly 9 o’clock.
--Oops! (Look at his watch). I guess you’re right.
--Why were you so tired?
--Well, I stayed up late last night to watch the stars.
--That’s nice. They must be pretty.
--Yes, they are.
Then ask students to make up their own dialogues. They may discuss and practice in pairs.
In this unit, we have read the first two parts of a travel journal and have listened to the third part of the travel journal. What is the difference between a journal and a diary? Let’s read the passage on page 23 and find out the difference between the two.
Now let’s do a writing practice. Imagine that you are a friend of Wang Wei. Write a short letter to her and ask her to describe: how she feels, what she is doing, and some place you want to know about. Then wish her well on her journey by using at least two of these expressions:
Have a nice/good time. Have a nice/good trip. Take care.
Good luck on your journey. Say “Hello” to …. Write to me.
Give my best/love wishes to …. Have fun.
Tell the students that they can refer to the following steps.
In pairs. Choose the details from the journey that are most interesting. Think of what else you would like to know about the journey. Write these ideas down as questions.
Now choose two or three of the best questions for your letter. Each question should have another sentence explaining why you want to know this information.
Put them in an order that makes sense.
Begin your letter as shown in the textbook and add your questions for Wang Wei.
Finish your letter as shown in the textbook.
A sample writing:
Hi, brave little Wei,
How I worry about you and Wang Kun! Do you have a good time now? I hope so. What are you doing now? Are you still in Laos? Can you tell me something about people’s life there? When are you leaving for Cambodia? When you get there, tell me about the Buddhist temples there. Please send some photos with your next letter! Well, Have a good trip and don’t forget to write to me! Give my best wishes to Wang Kun. Good luck on your journey.
Take care!

一)、課內(nèi)重視聽(tīng)講，課后及時(shí)復(fù)習(xí)。
新知識(shí)的接受，數(shù)學(xué)能力的培養(yǎng)主要在課堂上進(jìn)行，所以要特點(diǎn)重視課內(nèi)的學(xué)習(xí)效率，尋求正確的學(xué)習(xí)方法。上課時(shí)要緊跟老師的思路，積極展開(kāi)思維預(yù)測(cè)下面的步驟，比較自己的解題思路與教師所講有哪些不同。特別要抓住基礎(chǔ)知識(shí)和基本技能的學(xué)習(xí)，課后要及時(shí)復(fù)習(xí)不留疑點(diǎn)。首先要在做各種習(xí)題之前將老師所講的知識(shí)點(diǎn)回憶一遍，正確掌握各類(lèi)公式的推理過(guò)程，應(yīng)盡量回憶而不采用不清楚立即翻書(shū)之舉。認(rèn)真獨(dú)立完成作業(yè)，勤于思考，從某種意義上講，應(yīng)不造成不懂即問(wèn)的學(xué)習(xí)作風(fēng)，對(duì)于有些題目由于自己的思路不清，一時(shí)難以解出，應(yīng)讓自己冷靜下來(lái)認(rèn)真分析題目，盡量自己解決。在每個(gè)階段的學(xué)習(xí)中要進(jìn)行整理和歸納總結(jié)，把知識(shí)的點(diǎn)、線、面結(jié)合起來(lái)交織成知識(shí)網(wǎng)絡(luò)，納入自己的知識(shí)體系。
二)、適當(dāng)多做題，養(yǎng)成良好的解題習(xí)慣。
要想學(xué)好數(shù)學(xué)，多做題是難免的，熟悉掌握各種題型的解題思路。剛開(kāi)始要從基礎(chǔ)題入手，以課本上的習(xí)題為準(zhǔn)，反復(fù)練習(xí)打好基礎(chǔ)，再找一些課外的習(xí)題，以幫助開(kāi)拓思路，提高自己的分析、解決能力，掌握一般的解題規(guī)律。對(duì)于一些易錯(cuò)題，可備有錯(cuò)題集，寫(xiě)出自己的解題思路和正確的解題過(guò)程兩者一起比較找出自己的錯(cuò)誤所在，以便及時(shí)更正。在平時(shí)要養(yǎng)成良好的解題習(xí)慣。讓自己的精力高度集中，使大腦興奮，思維敏捷，能夠進(jìn)入最佳狀態(tài)，在考試中能運(yùn)用自如。實(shí)踐證明：越到關(guān)鍵時(shí)候，你所表現(xiàn)的解題習(xí)慣與平時(shí)練習(xí)無(wú)異。如果平時(shí)解題時(shí)隨便、粗心、大意等，往往在大考中充分暴露，故在平時(shí)養(yǎng)成良好的解題習(xí)慣是非常重要的。
三)、調(diào)整心態(tài)，正確對(duì)待考試。
首先，應(yīng)把主要精力放在基礎(chǔ)知識(shí)、基本技能、基本方法這三個(gè)方面上，因?yàn)槊看慰荚囌冀^大部分的也是基礎(chǔ)性的題目，而對(duì)于那些難題及綜合性較強(qiáng)的題目作為調(diào)劑，認(rèn)真思考，盡量讓自己理出頭緒，做完題后要總結(jié)歸納。調(diào)整好自己的心態(tài)，使自己在任何時(shí)候鎮(zhèn)靜，思路有條不紊，克服浮躁的情緒。特別是對(duì)自己要有信心，永遠(yuǎn)鼓勵(lì)自己，除了自己，誰(shuí)也不能把我打倒，要有自己不垮，誰(shuí)也不能打垮我的自豪感。
在考試前要做好準(zhǔn)備，練練常規(guī)題，把自己的思路展開(kāi)，切忌考前去在保證正確率的前提下提高解題速度。對(duì)于一些容易的基礎(chǔ)題要有十二分把握拿全分;對(duì)于一些難題，也要盡量拿分，考試中要學(xué)會(huì)嘗試得分，使自己的水平正常甚至超常發(fā)揮。
由此可見(jiàn)，要把數(shù)學(xué)學(xué)好就得找到適合自己的學(xué)習(xí)方法，了解數(shù)學(xué)學(xué)科的特點(diǎn)，使自己進(jìn)入數(shù)學(xué)的廣闊天地中去。
高中數(shù)學(xué)必修一課件 篇11
通過(guò)第一章《空間幾何體》的學(xué)習(xí)，學(xué)生對(duì)于立體幾何已經(jīng)有了初步的認(rèn)識(shí)，能夠識(shí)別棱柱、棱錐、棱臺(tái)、圓柱、圓錐、圓臺(tái)、球，并理解它們的幾何特征。但是這種理解還只是建立在觀察、感知的基礎(chǔ)上的，對(duì)于原理學(xué)生是不明確的，所以學(xué)生此時(shí)有很強(qiáng)的求知欲，急于想搞清楚為什么;同時(shí)學(xué)生經(jīng)過(guò)高中一年的學(xué)習(xí)，已經(jīng)具備了一定的邏輯推理能力，只是缺乏訓(xùn)練，不夠嚴(yán)密，不夠清晰;有一定的自主探究和合作學(xué)習(xí)的能力，但有待提高，并愿意動(dòng)手并參與分組討論。
