Step 3 Analyzing article structureActivity 31. Teachers raise questions to guide students to analyze the chapter structure of this diary and think about how to describe the festival experience. (1)What should be included in the opening/body/closing paragraph(s)?(2)How did the writer arrange his/her ideas?(3)What kind of interesting details did the writer describe?(4)How did the writer describe his/her feelings/emotions during the event?2. Students read and compare the three sentence patterns in activity 2. Try to rewrite the first paragraph of the diary with these three sentence patterns. After that, students exchange corrections with their partners. Such as:●This was my first time spending three days experiencing the Naadam Festival in China’s Inner Mongolia Autonomous Region and it was an enjoyable and exciting experience. ●I'll never forget my experience at the Naadam Festival because it was my first time to watch the exciting Mongolian games of horse racing, wrestling, and archery so closely. ●I'll always remember my first experience at the Naadam Festival in China’s Inner Mongolia Autonomous Region because it was so amazing to spend three days witnessing a grand Mongolian ceremony. Step 4 Accumulation of statementsActivity 41. Ask the students to read the diary again. Look for sentences that express feelings and emotions, especially those with the -ing form and the past participle. Such as:● …h(huán)orse racing, wrestling, and archery, which are all so exciting to watch. ● some amazing performances● I was surprised to see…● I was a little worried about. . . ● feeling really tiredOther emotional statements:●I absolutely enjoyed the archery, too, but the horse races were my favourite part. ●I'm finally back home now, feeling really tired, but celebrating Naadam with my friend was totally worth it. ●He invited me back for the winter to stay in a traditional Mongolian tent and cat hot pot. I can’t wait!2. In addition to the use of the -ing form and the past participle, the teacher should guide the students in the appreciation of these statements, ask them to memorize them, and encourage them to use them reasonably in writing practice.
新人教版高中英語必修3Unit 4 Space Exploration-Listening&Speaking＆Talking教學設計二
The themes of this part are “Talk about how to become an astronaut” and “Talk about life in space”. As Neil Armstrong said “Mystery creates wonder and wonder is the basis of man’s desire to understand. Space is difficult for human to reach, therefore, humans are full of wonders about it. However, if wanting to achieve the dream of reaching the Moon, some of our human should work hard to be an astronaut at first. Part A(Talk about how to become an astronaut) is a radio interview in a radio studio, where the host asked the Chinese astronauts about his story how to become an astronaut. Yang Liwei told his dreamed to be an astronaut since childhood. Then he worked hard to get into college at 22. The next 10 years, he gradually became an experienced pilot. At the same time, to be an astronaut, he had to study hard English, science and astronomy and trained hard to keep in good physical and mental health and to practise using space equipment. Part B (Talk about life in space) is also an interview with the astronaut Brown, who is back on the earth. The host Max asked about his space life, such as his emotion about going back the earth, the eating, shower, brushing, hobbies and his work. Part A and Part B are interviews. So expressing curiosity about the guests’ past life is a communicative skill, which students should be guided to learn.1. Students can get detailed information about how Yang Liwei became an astronaut and Max’s space life.2. Students learn to proper listening strategy to get detailed information---listening for numbers and taking notes.3.

⑦在我看來, 探索太空是值得的。As far as I am concerned, it is worthwhile to explore the space.Step 10 Writing---draftRecently, students in our class have had heated a discussion on whether space is worth exploring. Students hold different ideas about it.30% of us think space exploration is not worthwhile. They think space is too far away from us and our daily life and is a waste of money. And the money spent on space exploration can be used to solve the earth’s problems such as starvation and pollution.On the other hand，70% think space is worth exploring because we have benefited a lot from it，such as using satellites for communication and weather forecast. What’s more，with further space research，we may solve the population problem by moving to other planets one day. Also，space research will enable us to find new sources to solve the problem of energy shortages on the earth.As far as I am concerned, it is worthwhile to explore the space. Not only can it promote the development of society but also enrich our life. Step 11 Pair workExchange drafts with a partner. Use this checklist to help your partner revise his/her draft.1.Does the writer explain why he/she changed/wanted to change?2.Does the writer tell how the changes have improved or will improve his/her life?3.Is the text well－organised?4.Does the writer use words and expressions to show similarities and differences?5.Are there any grammar or spelling errors?6.Does the writer use correct punctuation？
人教版高中語文必修3《善待生命 學習論證》教案2篇
論證方法之引證法如何用好引證法：1.所引用的名言警句等針對性要強。每句名言都產生于特定的背景，都應用于特定的交際目的，即使談同一個問題，也有不少名言可供選取。2.要簡潔，不宜過多。議論是在發(fā)表自己的見解而不是在介紹他人的見解。引用他人的話，目的是為了讓讀者更加信服自己的話。3.要注意直接引用和間接引用的區(qū)別。直接引用務求文字、甚至標點均準確無誤；間接引用只須述其大意，但要注意人稱的轉換。論證方法之喻證法喻證法是用設喻來論證論點的方法。在議論文中，設喻可以使論點更易懂、更風趣、更容易獲得讀者的認同。喻證法能化抽象為具體、化艱深為淺顯、化枯燥為生動。論證方法之喻證法如何用好喻證法：1.以小見大，就近取譬。要精選生活中細小的、人們熟悉的事物做為設喻的喻體。2.喻體不求形似，只求神似。做為喻證的喻體與做為比喻的喻體不同。比喻的喻體是為了強調特征，描繪事物，側重形似，以形比形；而喻證的喻體是為了闡發(fā)觀點，以正視聽，力求神似，以義取形。

新人教版高中英語必修3Unit 5 The Value of Money-Reading and Thinking教學設計一
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.

教學重點1．自由落體運動的概念及探究自由落體運動的過程。2．掌握自由落體運動規(guī)律，并能運用其解決實際問題。教學難點演示實驗和探究實驗的技巧及自由落體運動規(guī)律的得出.教學過程設計思想：1、 先用游戲激發(fā)學生學習興趣，順理成章地研究落體運動；2、 通過演示實驗讓學生自己總結出物體下落快慢不同的主要原因是空氣阻力，從而猜想若沒有空氣阻力會怎樣；3、 用牛頓管實驗驗證猜想，引入了新的理想運動模型：自由落體運動。講述1971年宇航員做的實驗，加深印象；4、 了解地球表面物體下落運動近似成自由落體運動的條件；5、 著手研究自由落體運動的規(guī)律，利用打點計時器進行研究，得到結論；6、 總結自由落體運動特點及重力加速度；7、 應用訓練
人教版新課標高中物理必修1力學單位制教案2篇
一、教材分析在初中階段，物理量單位的學習是學生較為困惑的問題之一。前面關于1N的規(guī)定給學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。使得學生感動物理太復雜。事實上，只有把單位制放在整個物理學框架中加以認識，并且知識有了一定的積累。經(jīng)歷了充分的學習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，也逐漸成為科學研究中計算和運用的一種規(guī)范約束。中學生應該注意學習，逐步習慣，在記錄、表達和計算中規(guī)范使用。二、教學目標（一）知識與技能1．了解什么是單位制，知道力學中的三個基本單位；2．認識單位制在物理計算中的作用

演示實驗1、將一張紙和一張金屬片在同一高度同時釋放，結果金屬片先著地。教師不發(fā)表意見，繼續(xù)做實驗。分別將實驗內容和實驗結果板書在黑板上。2、將剛才的紙片緊緊捏成一團，再次與硬幣同時釋放，結果兩者幾乎同時落地。3、將兩個完全一樣的紙片，一個捏成團，一個平展，則紙團下落快。師：物體下落快慢是由質量決定嗎？生：不是的！師：為什么這樣說？生：第2個實驗和第三實驗都說明了這個問題，特別是第3個問題，質量一樣卻下落有快慢之分。師：那你現(xiàn)在覺得物體下落快慢由什么因素決定呢？生：我想應該是空氣阻力。猜想師：如果影響物體下落快慢的因素是空氣阻力，那么在沒有空氣阻力，物體的下落快慢應該是一樣的，這種猜想是不是正確呢？我們來做一個實驗驗證一下。
