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.

人教版高中地理必修3第四章第一節(jié)區(qū)域農(nóng)業(yè)發(fā)展教案
1．根據(jù)下面的材料，歸納珠江三角洲發(fā)展基塘生產(chǎn)有利的地理條件。珠江三角洲地勢低平，河網(wǎng)密布，降水充沛。北回歸線從珠江三角洲的北部穿過。桑樹和甘蔗主要分布于熱帶和亞熱帶。廣州是古代海上絲綢之路的起始地之一。水產(chǎn)品在廣東人的食物結(jié)構(gòu)中占有較大的比重。點撥珠江三角洲地區(qū)發(fā)展基塘農(nóng)業(yè)生產(chǎn)有利條件可以結(jié)合材料，歸納為三個方面：地形、氣候、市場（當(dāng)?shù)睾秃Ｍ猓┚唧w分析略。2．圖4．16所示的基塘生產(chǎn)將哪些產(chǎn)業(yè)聯(lián)系起來?哪些副產(chǎn)品(或廢棄物)被充分利用起來?這種聯(lián)系對農(nóng)村經(jīng)濟發(fā)展有什么作用?點撥基塘生產(chǎn)環(huán)節(jié)將種植業(yè)（桑、蔗等）、養(yǎng)殖業(yè)（養(yǎng)蠶、養(yǎng)魚）、工業(yè)（絲廠、糖廠）等幾種產(chǎn)業(yè)緊密的聯(lián)系在一起。在此環(huán)節(jié)中，塘泥、蠶沙（蠶屎）、蠶蛹、繅絲、濾泥、蔗葉等副產(chǎn)品被充分的回收利用。養(yǎng)蠶業(yè)、蔗糖加工業(yè)同塘魚養(yǎng)殖業(yè)緊密結(jié)合，作為一種綜合的經(jīng)營，幾者之間相互依存、相互促進、揚長補短，有機地循環(huán)聯(lián)系起來。
人教版高中地理必修3第五章第二節(jié)產(chǎn)業(yè)轉(zhuǎn)移教案
1．閱讀圖5．16，說明產(chǎn)業(yè)向國外轉(zhuǎn)移對日本經(jīng)濟的不利影響。點撥：圖5．16直觀的顯示了產(chǎn)業(yè)轉(zhuǎn)移對日本經(jīng)濟的不利影響：形成“產(chǎn)業(yè)轉(zhuǎn)移出去的多，轉(zhuǎn)移進來的少→國內(nèi)生產(chǎn)投資不足，生產(chǎn)困難→市場萎縮→產(chǎn)業(yè)向外轉(zhuǎn)移，外資不愿進入”的惡性循環(huán)。2．盡管重化工業(yè)的環(huán)境污染比較嚴(yán)重，但是卻能為工業(yè)化的發(fā)展提供堅實的基礎(chǔ)，因此成為發(fā)達(dá)工業(yè)的象征。日本、韓國的經(jīng)濟發(fā)展都經(jīng)歷了由輕工業(yè)(勞動密集型)到重化工業(yè)(資源密集型和資金密集型)到高科技工業(yè)(技術(shù)密集型)的階段。(1）為什么日本、韓國在重點發(fā)展重化工業(yè)之前，要先發(fā)展勞動密集型工業(yè)?點撥：重化工業(yè)的發(fā)展一方面需要有一定的工業(yè)基礎(chǔ)和技術(shù)工人，另一方面需要投入大量的資金，先發(fā)展勞動密集型工業(yè)有利于利用勞動力資源豐富且廉價的優(yōu)勢，積累資金和造就產(chǎn)業(yè)工人。所以，勞動力豐富的發(fā)展中國家或地區(qū)的工業(yè)化往往從優(yōu)先發(fā)展勞動密集型工業(yè)開始。

4．They were going to find someone to take part in their bet when they saw Henry walking on the street outside.[歸納]1．過去將來時的基本構(gòu)成和用法過去將來時由“would＋動詞原形”構(gòu)成，主要表示從過去某一時間來看將要發(fā)生的動作(尤其用于賓語從句中)，還可以表示過去的動作習(xí)慣或傾向。Jeff knew he would be tired the next day.He promised that he would not open the letter until 2 o'clock.She said that she wouldn't do that again.2．表示過去將來時的其他表達(dá)法(1)was/were going to＋動詞原形：該結(jié)構(gòu)有兩個主要用法，一是表示過去的打算，二是表示在過去看來有跡象表明將要發(fā)生某事。I thought it was going to rain.(2)was/were to＋動詞原形：主要表示過去按計劃或安排要做的事情。She said she was to get married next month.(3)was/were about to＋動詞原形：表示在過去看來即將要發(fā)生的動作，由于本身已含有“即將”的意味，所以不再與表示具體的將來時間狀語連用。I was about to go to bed when the phone rang.(4)was/were＋現(xiàn)在分詞：表示在過去看來即將發(fā)生的動作，通?？捎糜谠摻Y(jié)構(gòu)中的動詞是come，go，leave，arrive，begin，start，stop，close，open，die，join，borrow，buy等瞬間動詞。Jack said he was leaving tomorrow.

3．作者為什么不直接描寫人們看見東西呢？請同學(xué)們找出其中的細(xì)節(jié)描寫，并說明有什么表達(dá)效果。答：側(cè)面烘托，正是作者高明之處，這也是許多佳作常用之法。細(xì)節(jié)描寫往往會成為事情的切入點和突破口，一篇佳作往往離不開一些細(xì)節(jié)描寫，本文也不例外，有些細(xì)節(jié)描寫耐人尋味，如：“德國人撤退時炸毀的布熱金卡毒氣室和焚尸爐廢墟上，雛菊花在怒放?！薄斑@是一個二十多歲的姑娘，長得豐滿，可愛，皮膚細(xì)白，金發(fā)碧眼。她在溫和地微笑著，似乎是為著一個美好而又隱秘的夢想而微笑?！?.句子賞析：“對另外一些人來說，這樣一個事實使他們終生難忘：在德國人撤退時炸毀的布熱金卡毒氣室和焚尸爐廢墟上，雛菊花在怒放?！泵鞔_：一邊是戕害生命的毒氣室和焚尸爐，一邊是生機勃勃的生命，兩種反差極大的事物擺在一起。表達(dá)了作者對納粹的諷刺：納粹的殘暴終歸阻止不了生命的進程。同時也表達(dá)了作者的控訴：生命的綻放是人世間最美好的事情，對生命的戕害是最惡劣的罪行。

1．懸念法懸念法又稱關(guān)子。它是作者為了激發(fā)那種“緊張與期待的心理活動”，在行文中有意采取的一種積極而有效的手段。這種手段包括“設(shè)懸”和“解懸”兩方面。所謂 “設(shè)懸”就是設(shè)置懸念，即在情節(jié)發(fā)生發(fā)展的關(guān)鍵時刻或人物命運攸關(guān)的重要關(guān)頭，敘述戛然而止，轉(zhuǎn)敘他事。從而引起讀者強烈的尋根問底的興趣。所謂“解懸” 也叫“釋懸”，就是指在情節(jié)發(fā)展的特定階段，通過矛盾的解決，揭示事情原委和人物命運的結(jié)局，使讀者的期待心理得以滿足。如《驛路梨花》，當(dāng)人們正為露宿而發(fā)愁時出現(xiàn)了一間神秘的小屋，小屋的主人是誰呢？猜想間，有人來了，但也不是屋子主人，那小屋子的主人是誰呢？終于知道了小屋是解放軍蓋的，但為什么要蓋這間小屋呢？這樣“設(shè)懸——釋懸——帶出新懸念”，環(huán)環(huán)相扣、層層遞進，使文章韻味無窮。

生：環(huán)境承載力是指環(huán)境能持續(xù)供養(yǎng)的人口數(shù)量。師：對了。但是有同學(xué)仍然會感到這是一個很抽象的概念。下面我們具體來了解什么是環(huán)境承載力。我們可以從兩個部分去理解：一、環(huán)境，它主要是指環(huán)境的單個要素（如：土地、水、氣候、植被等。）及其組合方式。二、是承載力，它指在特定的條件下，具體某事物能承受的某種活動的最大值。那環(huán)境承載力的科學(xué)定義是怎樣表達(dá)的呢？生：環(huán)境承載力是指某一時期，某種狀態(tài)條件下，某地區(qū)環(huán)境所能承受的人類活動作用的閾值。師：很對。 我們可以用一個生動的例子來說明。一只木桶里面的水的多少在底面積固定不變的情況下是由哪塊木板來決定？生：最短的那塊。師：確實如此。這就是我們平常所講的 “木桶效應(yīng)”。那影響環(huán)境承載力的大小也是由環(huán)境個要素里面最緊缺的那個要素來決定的。下面我們用一個例子來印證一下。
人教版新課標(biāo)高中物理必修1力學(xué)單位制教案2篇
一、教材分析在初中階段，物理量單位的學(xué)習(xí)是學(xué)生較為困惑的問題之一。前面關(guān)于1N的規(guī)定給學(xué)生的印象總好像是有些隨意。尤其是牛頓、帕斯卡、安培、伏特、焦耳、瓦特等單位的規(guī)定。使得學(xué)生感動物理太復(fù)雜。事實上，只有把單位制放在整個物理學(xué)框架中加以認(rèn)識，并且知識有了一定的積累。經(jīng)歷了充分的學(xué)習(xí)過程后才能體會物理量單位的命名和使用規(guī)則。體會到其中對一些單位進行規(guī)定的合理性和方便特征。物理學(xué)單位中，有很少幾個基本物理量，它們的單位就是基本單位。在進行了這種選定之后，其它物理量的單位就是根據(jù)它的定義式，有所選擇的其他物理量的單位共同確定的。國際單位制的建立和使用，不僅方便了國際間的交流，也逐漸成為科學(xué)研究中計算和運用的一種規(guī)范約束。中學(xué)生應(yīng)該注意學(xué)習(xí)，逐步習(xí)慣，在記錄、表達(dá)和計算中規(guī)范使用。二、教學(xué)目標(biāo)（一）知識與技能1．了解什么是單位制，知道力學(xué)中的三個基本單位；2．認(rèn)識單位制在物理計算中的作用

（二）進行新課1、動能與勢能的相互轉(zhuǎn)化演示實驗1：如右圖，用細(xì)線、小球、帶有標(biāo)尺的鐵架臺等做實驗。把一個小球用細(xì)線懸掛起來，把小球拉到一定高度的A點，然后放開，小球在擺動過程中，重力勢能和動能相互轉(zhuǎn)化。我們看到，小球可以擺到跟A點等高的C點，如圖甲。如果用尺子在某一點擋住細(xì)線，小球雖然不能擺到C點，但擺到另一側(cè)時，也能達(dá)到跟A點相同的高度，如圖乙。問題：這個小實驗中，小球的受力情況如何？各個力的做功情況如何？這個小實驗說明了什么？學(xué)生觀察演示實驗，思考問題，選出代表發(fā)表見解。小球在擺動過程中受重力和繩的拉力作用。拉力和速度方向總垂直，對小球不做功；只有重力對小球能做功。實驗證明，小球在擺動過程中重力勢能和動能在不斷轉(zhuǎn)化。在擺動過程中，小球總能回到原來的高度?？梢姡亓菽芎蛣幽艿目偤捅３植蛔?。即機械能保持不變。

二、課堂教學(xué)（課前由科代表發(fā)回預(yù)習(xí)學(xué)案）1、教師根據(jù)預(yù)習(xí)學(xué)案檢查結(jié)果提出問題（用多媒體展示），引導(dǎo)全班討論（重點討論：①、為什么動能的表達(dá)式一定是 mV2 ？你如何得出這個結(jié)論？②、力在一個過程中對物體所做的功，和物體在這個過程中動能的變化量有什么關(guān)系？你如何得出這個結(jié)論？這個做功的力和F=ma中的力F有什么關(guān)系）。有困難的小組應(yīng)及時問老師。老師在這個過程中巡視指導(dǎo)。2、學(xué)生自主閱讀課文“7 動能和動能定理”中的“動能的表達(dá)式”，然后完成如下練習(xí)（教師在此過程中巡視指導(dǎo)）：2.1嘗試推出動能的表達(dá)式（鼓勵會推導(dǎo)的同學(xué)積極上臺板演，老師引導(dǎo)討論）。2.2寫出動能的小結(jié)（認(rèn)真閱讀教材p66倒數(shù)第二段、第三段，結(jié)合你推導(dǎo)動能表達(dá)式的過程，認(rèn)真思考后四人一組討論：①、動能是矢量還是標(biāo)量？②、動能的單位是什么？③、你認(rèn)為應(yīng)從哪幾方面來理解動能？）
