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.

3．作者為什么不直接描寫人們看見(jiàn)東西呢？請(qǐng)同學(xué)們找出其中的細(xì)節(jié)描寫，并說(shuō)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(huì)成為事情的切入點(diǎn)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(guó)人撤退時(shí)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(gè)二十多歲的姑娘，長(zhǎng)得豐滿，可愛(ài)，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(gè)美好而又隱秘的夢(mèng)想而微笑。”4.句子賞析：“對(duì)另外一些人來(lái)說(shuō)，這樣一個(gè)事實(shí)使他們終生難忘：在德國(guó)人撤退時(shí)炸毀的布熱金卡毒氣室和焚尸爐廢墟上，雛菊花在怒放。”明確：一邊是戕害生命的毒氣室和焚尸爐，一邊是生機(jī)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(duì)納粹的諷刺：納粹的殘暴終歸阻止不了生命的進(jìn)程。同時(shí)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(duì)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(dòng)”，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(shí)刻或人物命運(yùn)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(qiáng)烈的尋根問(wèn)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(guò)矛盾的解決，揭示事情原委和人物命運(yùn)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(shí)出現(xiàn)了一間神秘的小屋，小屋的主人是誰(shuí)呢？猜想間，有人來(lái)了，但也不是屋子主人，那小屋子的主人是誰(shuí)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(jìn)，使文章韻味無(wú)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(duì)了。但是有同學(xué)仍然會(huì)感到這是一個(gè)很抽象的概念。下面我們具體來(lái)了解什么是環(huán)境承載力。我們可以從兩個(gè)部分去理解：一、環(huán)境，它主要是指環(huán)境的單個(gè)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(dòng)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(shí)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(dòng)作用的閾值。師：很對(duì)。 我們可以用一個(gè)生動(dòng)的例子來(lái)說(shuō)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(lái)決定？生：最短的那塊。師：確實(shí)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(gè)要素里面最緊缺的那個(gè)要素來(lái)決定的。下面我們用一個(gè)例子來(lái)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(wèn)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(dòng)物理太復(fù)雜。事實(shí)上，只有把單位制放在整個(gè)物理學(xué)框架中加以認(rèn)識(shí)，并且知識(shí)有了一定的積累。經(jīng)歷了充分的學(xué)習(xí)過(guò)程后才能體會(huì)物理量單位的命名和使用規(guī)則。體會(huì)到其中對(duì)一些單位進(jìn)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(gè)基本物理量，它們的單位就是基本單位。在進(jìn)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(guó)際單位制的建立和使用，不僅方便了國(guó)際間的交流，也逐漸成為科學(xué)研究中計(jì)算和運(yùn)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(jì)算中規(guī)范使用。二、教學(xué)目標(biāo)（一）知識(shí)與技能1．了解什么是單位制，知道力學(xué)中的三個(gè)基本單位；2．認(rèn)識(shí)單位制在物理計(jì)算中的作用

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。

（二）進(jìn)行新課1、動(dòng)能與勢(shì)能的相互轉(zhuǎn)化演示實(shí)驗(yàn)1：如右圖，用細(xì)線、小球、帶有標(biāo)尺的鐵架臺(tái)等做實(shí)驗(yàn)。把一個(gè)小球用細(xì)線懸掛起來(lái)，把小球拉到一定高度的A點(diǎn)，然后放開，小球在擺動(dòng)過(guò)程中，重力勢(shì)能和動(dòng)能相互轉(zhuǎn)化。我們看到，小球可以擺到跟A點(diǎn)等高的C點(diǎn)，如圖甲。如果用尺子在某一點(diǎn)擋住細(xì)線，小球雖然不能擺到C點(diǎn)，但擺到另一側(cè)時(shí)，也能達(dá)到跟A點(diǎn)相同的高度，如圖乙。問(wèn)題：這個(gè)小實(shí)驗(yàn)中，小球的受力情況如何？各個(gè)力的做功情況如何？這個(gè)小實(shí)驗(yàn)說(shuō)明了什么？學(xué)生觀察演示實(shí)驗(yàn)，思考問(wèn)題，選出代表發(fā)表見(jiàn)解。小球在擺動(dòng)過(guò)程中受重力和繩的拉力作用。拉力和速度方向總垂直，對(duì)小球不做功；只有重力對(duì)小球能做功。實(shí)驗(yàn)證明，小球在擺動(dòng)過(guò)程中重力勢(shì)能和動(dòng)能在不斷轉(zhuǎn)化。在擺動(dòng)過(guò)程中，小球總能回到原來(lái)的高度?？梢?jiàn)，重力勢(shì)能和動(dòng)能的總和保持不變。即機(jī)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(wèn)題（用多媒體展示），引導(dǎo)全班討論（重點(diǎn)討論：①、為什么動(dòng)能的表達(dá)式一定是 mV2 ？你如何得出這個(gè)結(jié)論？②、力在一個(gè)過(guò)程中對(duì)物體所做的功，和物體在這個(gè)過(guò)程中動(dòng)能的變化量有什么關(guān)系？你如何得出這個(gè)結(jié)論？這個(gè)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(shí)問(wèn)老師。老師在這個(gè)過(guò)程中巡視指導(dǎo)。2、學(xué)生自主閱讀課文“7 動(dòng)能和動(dòng)能定理”中的“動(dòng)能的表達(dá)式”，然后完成如下練習(xí)（教師在此過(guò)程中巡視指導(dǎo)）：2.1嘗試推出動(dòng)能的表達(dá)式（鼓勵(lì)會(huì)推導(dǎo)的同學(xué)積極上臺(tái)板演，老師引導(dǎo)討論）。2.2寫出動(dòng)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(dòng)能表達(dá)式的過(guò)程，認(rèn)真思考后四人一組討論：①、動(dòng)能是矢量還是標(biāo)量？②、動(dòng)能的單位是什么？③、你認(rèn)為應(yīng)從哪幾方面來(lái)理解動(dòng)能？）
