8. However, the more polite you are, the less likely it is you will be attacked. 然而, 你越有禮貌, 你被攻擊的可能性就越小。 Step 8 Writing---the articleHow to stay safe in the online chat roomToday I thought I’d blog about a question that has been asked many times--- how do you stay safe online and avoid bad experiences in the online chat room ? I’m not an expert, but many years as a blogger have taught me a thing or two.First of all, there’s the golden rule of the Internet: keep out of what makes you uneasy. Don’t post comments or click on anything. Second, protect your privacy. Don’t give out too much private information like your address, phone numbers, the ID numbers, etc. Third, be polite. If you are polite to others on the Internet, you won’t be attacked in normal situation. Finally, don’t believe in others easily and never meet someone you met online alone. It is very dangerous.Have you had any bad experiences online, or do you have some good advice for staying safe? Post your comments below!Step 9 Pair workExchange drafts with a partner. Use this checklist to help your partner revise his/her draft.1. Does the writer tell the reader what he/she know about the topic ?2. Are the tips and suggestions well organised ?3. Has the writer defined the new words ?4. Does the author include examples, comparison, or explanations ?5. Does the writer end by asking readers to leave comments and/or suggestions ?6. Can you find any grammar or spelling mistakes.Step 6 HomeworkPut up your revised draft in the classroom or read it to your class.

The Internet celebrity Gao Yifeng. Years ago, he owned 5 companies and the staffs over 1,000, but during the economy crisis, he became nothing but debt. He was so worried that his hair became white overnight. There was a time when he wanted to killed himself. But after listening to the song Start Over by Liu Huan, he decided to cheer himself up. He started a steamed bun shop and gradually became a national chain shops. Now he became successful again.Walter Haddon said, “Music is the medicine of a troubled mind.” Music contains such a pleasant and inspiring force. Music gave him courage and bravery. When he listened to the song, it made his spirit fly like a kite in the wind. Music gave him strength and brought him relief. It was the rock I leant on to become strong and to get through those hard times. I hope none of us have to go through the same kind of suffering that he did. At the same time, we all go through various periods when we feel sad or alone. During those times, music can help us in the same way that it helped him.

人教版高中歷史必修2古代商業(yè)的發(fā)展教案
中國古代商業(yè)的發(fā)展有哪些表現(xiàn)？綜觀中國古代歷史，商業(yè)在不同的歷史時期有不同的表現(xiàn)。主要表現(xiàn)在：（1）商業(yè)活動的場所的變化：先主要在城市中進行，后來農村集市貿易逐漸發(fā)展。唐時加快，明清時突出，出現(xiàn)了專業(yè)性的市集（如絲市、葉市、豬市等），以至逐漸形成了新興的市鎮(zhèn)（有的更是專業(yè)性的集散市集）；而不是先有農村商業(yè)，而后才有城市商業(yè)的發(fā)展。（2）交易內容的變化：商業(yè)開始時以販運、交流地區(qū)間的土特產品，經營統(tǒng)治者所需要的奢侈品為主要內容，以后隨著商品貨幣經濟的發(fā)展，市場商品種類增多、行業(yè)分細，為一般人民所需要的主要農副產品以及城市手工業(yè)所生產的大小商品在整個流通界地位提高。這種情況在宋代已經顯現(xiàn)。（3）交易媒介的變化：商品交換最原始的形態(tài)是物物交換，不存在交易的媒介。隨著商品交換的內容和地域的擴大，出現(xiàn)了以貝殼等為代表的一般等價物。
人教版新課標高中物理必修2動能和動能定理教案2篇
二、課堂教學（課前由科代表發(fā)回預習學案）1、教師根據(jù)預習學案檢查結果提出問題（用多媒體展示），引導全班討論（重點討論：①、為什么動能的表達式一定是 mV2 ？你如何得出這個結論？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系？你如何得出這個結論？這個做功的力和F=ma中的力F有什么關系）。有困難的小組應及時問老師。老師在這個過程中巡視指導。2、學生自主閱讀課文“7 動能和動能定理”中的“動能的表達式”，然后完成如下練習（教師在此過程中巡視指導）：2.1嘗試推出動能的表達式（鼓勵會推導的同學積極上臺板演，老師引導討論）。2.2寫出動能的小結（認真閱讀教材p66倒數(shù)第二段、第三段，結合你推導動能表達式的過程，認真思考后四人一組討論：①、動能是矢量還是標量？②、動能的單位是什么？③、你認為應從哪幾方面來理解動能？）
人教版新課標高中物理必修2生活中的圓周運動教案2篇
思考：洗衣機脫水時轉速高時容易甩干衣物，還是轉速低時容易甩干衣物？(2) 制作棉花糖的原理內筒與洗衣機的脫水筒相似，里面加入白砂糖，加熱使糖熔化成糖汁。內筒高速旋轉，黏稠的糖汁就做離心運動，從內筒壁的小孔飛散出去，成為絲狀到達溫度較低的外筒，并迅速冷卻凝固，變得纖細雪白，像一團團棉花。5.離心現(xiàn)象的防止在水平公路上行駛的汽車，轉彎時所需的向心力是由車輪與路面的靜摩擦力提供的。如果轉彎時速度過大，所需向心力F大于最大靜摩擦力Fmax，汽車將做離心運動而造成交通事故。因此，在公路彎道處，車輛行駛不允許超過規(guī)定的速度。當高速轉動的砂輪或者飛輪內部分子間相互作用力不足以提供所需向心力時，離心運動就會使他們破裂，甚至釀成事故。

（二）進行新課1、動能與勢能的相互轉化演示實驗1：如右圖，用細線、小球、帶有標尺的鐵架臺等做實驗。把一個小球用細線懸掛起來，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線，小球雖然不能擺到C點，但擺到另一側時，也能達到跟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化。在擺動過程中，小球總能回到原來的高度?？梢?，重力勢能和動能的總和保持不變。即機械能保持不變。
人教版新課標高中物理必修2萬有引力定律教案2篇
3.適用條件（1）萬有引力定律只適用于質點間引力大小的計算。當兩物體間的距離遠遠大于每個物體的尺寸時，物體可以看成質點，直接使用萬有引力定律計算。（模型）研究相互接觸的兩個人之間的萬有引力時，不能把他們看作質點。（2）當兩物體是質量均勻分布的球體時，它們間的引力也可直接用公式計算，但式中的r是指兩球心間距離。研究太陽和地球之間的萬有引力，可以把它們看作質量均勻的球體。當研究物體不能看成質點時，可以把物體假想分割成無數(shù)個質點，求出兩個物體上每個質點與另一物體上所有質點的萬有引力，然后求合力，這是微積分的思想。萬有引力定律產生于對太陽系行星運動的研究，但它對物質運動的適用性卻要廣泛得多。可以這樣說，宇宙中凡有引力參與的一切復雜的現(xiàn)象，無不要歸結到這樣一條十分簡潔的定律之中，這不能不使人驚嘆宇宙萬物超乎尋常的和諧及人類理性思考所具有的統(tǒng)攝力。
人教版新課標高中物理必修2曲線運動教案2篇
1、教師先演示投影：把小鋼珠放在黑墨水瓶蓋里轉一下（內有一點點墨水），再放在半圓形有機玻璃軌道上運動并飛出，讓鋼珠在白紙上留下痕跡，同樣在3/5半圓周，4/5半圓周上運動飛出，讓學生猜測飛出方向由什么特點？（有機玻璃板說明：厚約5毫米，略小于小鋼珠直徑，圓弧半徑15厘米，MN邊稍長些，以便過MN做直線，根據(jù)半徑大小確定圓心O位置。）學生猜想：切線方向師：已知圓弧半徑為15厘米。如何驗證？請用幾何方法作圖驗證。生：標出飛出點和圓心，做圓心和飛出點的連線，用量角尺量出該連線和飛出軌跡直線的夾角，是否90度。2、再分組實驗，提醒同桌配合，小心鋼珠滾跑。實驗完畢，要求作圖驗證，并互相討論交流。3、交流和結論：師：要引導學生得出正確的科學結論：“圓周運動的物體的速度方向為該點的切線方向”，而不能直接得出“曲線運動的的物體速度方向為該點的切線方向”。
人教版新課標高中物理必修2探究彈性勢能的表達式教案2篇
“做功的過程就是能量轉化過程”，這是本章教學中的一條主線。對于一種勢能，就一定對應于相應的力做功。類比研究重力勢能是從分析重力做功入手的，研究彈簧的彈性勢能則應從彈簧的彈力做功入手。然而彈簧的彈力是一個變力，如何研究變力做功是本節(jié)的一個難點，也是重點。首先，要引導學生通過類比重力做功和重力勢能的關系得出彈簧的彈力做功和彈簧的彈性勢能的關系。其次，通過合理的猜想與假設得出彈簧的彈力做功與哪些物理量有關。最后，類比勻變速直線運動求位移的方法，進行知識遷移，利用微元法的思想得到彈簧彈力做功的表達式，逐步把微分和積分的思想滲透到學生的思維中。本節(jié)課通過游戲引入課題，通過生活中拉弓射箭、撐桿跳高和彈跳蛙等玩具以及各種彈簧等實例來創(chuàng)設情景，提出問題。給學生感性認識，引起學生的好奇心；讓學生對彈簧彈力做功的影響因素進行猜想和假設，提出合理的推測，激發(fā)學生的探索心理，構思實驗，為定性探究打下基礎。然后，引導學生通過類比重力做功與重力勢能的關系得出彈簧彈性勢能與彈簧彈力做功的關系。

1．教材在學生的原有加速度概念的基礎上來討論“勻速圓周運動速度變化快慢”的問題，讓學生知道向心加速度能夠表示勻速圓周運動物體速度變化的快慢究竟是怎么一回事。2．教材把向心加速度安排在線速度和角速度知識之后，使學生對描述勻速圓周運動的幾個物理量有一個大致的了解。3．教材從了解運動的規(guī)律過渡到了解力跟運動關系的規(guī)律；把向心加速度放在向心力之前，從運動學的角度來學習向心加速度。4．教材為了培養(yǎng)學生“用事實說話”的“態(tài)度”，讓一切論述都合乎邏輯，改變了過去從向心力推導向心加速度的教學方式。1．采用理論、實驗、體驗相結合的教學安排。2．教師啟發(fā)引導，學生自主閱讀、思考，討論、交流。知識與技能1．會作矢量圖表示速度的變化量與速度之間的關系。2．加深理解加速度與速度、速度變化量的區(qū)別。3．體會勻速圓周運動向心加速度方向的分析方法。4．知道向心加速度的公式也適用于變速圓周運動；知道變速圓周運動的向心加速度的方向。
