Example:One day, a poor boy who was trying to pay his way through school by sending newspapers door to door found that he only had one dime(一角）left. He was so hungry that he decided to beg for a meal at the next house.However, he lost his nerve when a lovely young woman opened the door. Instead of a meal he asked for a drink of water. She thought he looked hungry so she brought him a large glass of milk. He drank it slowly, and then asked, “How much do I owe you?” “You don’t owe me anything,” she replied, “Mother has taught me never to accept pay for a kindness.” “Then I thank you from the bottom of my heart.” With these words, Howard Kelly left that house.Years later the woman became badly ill and was finally sent to the hospital in a big city. Dr. Howard Kelly, now famous, was called in. When he heard the name of the town she came from, a strange light filled his eyes. Dressed in his doctor’s clothes, Dr. Kelly went into her room and recognized her at once. From that day on, he gave special attention to her, and decided to do his best to save her life.At last the woman was saved. Dr. Kelly asked the business office to pass the final bill to him. He looked at it and then wrote something on the side. The bill was sent to the woman’s room. She was afraid to open it because she was sure that it would take the rest of her life to pay for it off. Finally she looked, and the note on the side of the bill caught her attention. She read these words: “Paid in full with a glass of milk, Dr. Howard Kelly.” Tear of joy flooded her eyes.

The story was quite successful in achieving its purpose, and I liked it because it had a clear moral.However, while the moral of the story is clear, the actions of the king seemed pointless to me, because none of the characters in the story learnt anything. For this reason, I think there are better stories that can be used to impress upon people with the need for personal responsibility.Step 8 Pair workExchange drafts with a partner. Use this checklist to help your partner revise his/her draft.1. Does the writer give a short description of the story ?2. Does the description include the most important details of the story ?3.

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.

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？）

“做功的過(guò)程就是能量轉(zhuǎn)化過(guò)程”，這是本章教學(xué)中的一條主線。對(duì)于一種勢(shì)能，就一定對(duì)應(yīng)于相應(yīng)的力做功。類比研究重力勢(shì)能是從分析重力做功入手的，研究彈簧的彈性勢(shì)能則應(yīng)從彈簧的彈力做功入手。然而彈簧的彈力是一個(gè)變力，如何研究變力做功是本節(jié)的一個(gè)難點(diǎn)，也是重點(diǎn)。首先，要引導(dǎo)學(xué)生通過(guò)類比重力做功和重力勢(shì)能的關(guān)系得出彈簧的彈力做功和彈簧的彈性勢(shì)能的關(guān)系。其次，通過(guò)合理的猜想與假設(shè)得出彈簧的彈力做功與哪些物理量有關(guān)。最后，類比勻變速直線運(yùn)動(dòng)求位移的方法，進(jìn)行知識(shí)遷移，利用微元法的思想得到彈簧彈力做功的表達(dá)式，逐步把微分和積分的思想滲透到學(xué)生的思維中。本節(jié)課通過(guò)游戲引入課題，通過(guò)生活中拉弓射箭、撐桿跳高和彈跳蛙等玩具以及各種彈簧等實(shí)例來(lái)創(chuàng)設(shè)情景，提出問(wèn)題。給學(xué)生感性認(rèn)識(shí)，引起學(xué)生的好奇心；讓學(xué)生對(duì)彈簧彈力做功的影響因素進(jìn)行猜想和假設(shè)，提出合理的推測(cè)，激發(fā)學(xué)生的探索心理，構(gòu)思實(shí)驗(yàn)，為定性探究打下基礎(chǔ)。然后，引導(dǎo)學(xué)生通過(guò)類比重力做功與重力勢(shì)能的關(guān)系得出彈簧彈性勢(shì)能與彈簧彈力做功的關(guān)系。

說(shuō)明：“倍增法”是一種重要的物理方法，歷史上庫(kù)侖在研究電荷間的相互作用力時(shí)曾用過(guò)此法，但學(xué)生在此前的物理學(xué)習(xí)中可能未曾遇到類似例子，因此引導(dǎo)學(xué)生通過(guò)交流，領(lǐng)會(huì)“倍增法”的妙處，這是本節(jié)課的一個(gè)要點(diǎn)．可用體育鍛煉中的“拉力器”來(lái)類比。（2）該方案消除摩擦力影響的方法：所用的消除方法與實(shí)驗(yàn)方案2一樣。也可使用氣墊導(dǎo)軌代替木板，以更好地消除摩擦影響。（3）小車速度的確定方法：①確定打出來(lái)的點(diǎn)大致呈現(xiàn)什么規(guī)律：先密后疏（變加速），再均勻分布（勻速）；②應(yīng)研究小車在哪個(gè)時(shí)刻的速度：在橡皮筋剛恢復(fù)原長(zhǎng)時(shí)小車的瞬時(shí)速度，即紙帶上的點(diǎn)剛開(kāi)始呈現(xiàn)均勻分布時(shí)的速度；③應(yīng)如何取紙帶上的點(diǎn)距以確定速度：由于實(shí)驗(yàn)器材和每次操作的分散性，尤其是橡皮筋不可能長(zhǎng)度、粗細(xì)完全一致，使得每次改變橡皮筋的條數(shù)后，紙帶上反映小車勻速運(yùn)動(dòng)的點(diǎn)數(shù)和點(diǎn)的位置，不一定都在事先的設(shè)定點(diǎn)（即用一條橡皮筋拉小車，橡皮筋剛好恢復(fù)原長(zhǎng)時(shí)紙帶上的點(diǎn)）處。

（給出儀器后先讓學(xué)生思考如何設(shè)計(jì)實(shí)驗(yàn)、安裝儀器、設(shè)計(jì)實(shí)驗(yàn)步驟，而后教師總結(jié)）實(shí)驗(yàn)步驟如下：①安裝調(diào)整斜槽 ：用圖釘把白紙釘在豎直板上，在木板的左上角固定斜槽。②調(diào)整木板 ：用懸掛在槽口的重錘線把木板調(diào)整到豎直方向，并使木板平面與小球下落的豎直面平行，然后把重錘線方向記錄到釘在木板上的白紙上，固定木板，使在重復(fù)實(shí)驗(yàn)的過(guò)程中，木板與斜槽的相對(duì)位置保持不變。③確定坐標(biāo)原點(diǎn)：把小球放在槽口處，用鉛筆記下小球在槽口時(shí)球心在木板上的水平投影點(diǎn)O，O即為坐標(biāo)原點(diǎn)。④描繪運(yùn)動(dòng)軌跡 ：用鉛筆的筆尖輕輕地靠在木板的平面上，不斷調(diào)整筆尖的位置，使從斜槽上滾下的小球正好碰到筆尖，然后就用鉛筆在該處白紙上點(diǎn)上一個(gè)黑點(diǎn)，這就記下了小球球心所對(duì)應(yīng)的位置。保證小球每次從槽上開(kāi)始滾下的位置都相同，用同樣的方法可找出小球平拋軌跡上的一系列位置。取下白紙，描繪小球做平拋運(yùn)動(dòng)的軌跡。
