The theme of the section is “Describe space facts and efforts to explore space”. Infinitives are one of non-finite verbs, as the subjects, objects, predicative, attributes and adverbials. This unit is about space exploration, which is a significant scientific activity, so every scientific activity has strong planning. Therefore, using the infinitives to show its purpose, explanations or restrictions is the best choice.1. Learn the structure, functions and features of infinitives.2. Learn to summarize some rules about infinitives to show purpose and modify.3. Learn to use infinitives in oral and writing English. 1. Learn the structure, functions and features of infinitives.2. Learn to summarize some rules about infinitives to show purpose and modify.3. Learn to use use infinitives in oral and writing English.Step 1 Lead in---Pair workLook at the following sentences and focus on the italicized infinitives. In pairs, discuss their functions. 1. I trained for a long time to fly airplanes as a fighter pilot..(作目的狀語)2. As we all know, an astronaut needs to be healthy and calm in order to work in space..(作目的狀語)3. First of all, you must be intelligent enough to get a related college degree..(作目的狀語)4. Some scientist were determined to help humans realise their dream to explore space..(作定語)5. On 12 April 1961, Yuri Gagarin became the first person in the world to go into space..(作定語)Summary:1. 不定式的結(jié)構(gòu):to+do原形。2. 分析上面的句子,我們知道在描述太空探索時,動詞不定式不僅可以用來表目的,還可以用來作定語,表修飾。

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. Students can learn related sentences or phrases to express their curiosity like “ I wish to know...” “I’d love to know...”4. Students can learn more about the space and astronauts, even be interested in working hard to be an astronaut

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.

Step 4: Listen again and decide if the following statements are true (T) or false (F).1 It was the first time Chen Liyan's story was reported. T口 F口2 Chen found 10,000 yuan in a small plastic bag in Taiyuan railway station口 F口3 Wang Zheng apologized to Chen because he couldn't offer her more money. T口 F口4 Chen took out a large loan to cure her daughter, T口 F口5 Wang set up a fundraising website for Chen's daughter after Chen told him about her situation. T口 F口Step 5:After listening, discuss the questions.1 What kind of person do you think Chen Liyan is?Chen Liyan is generous and honest because she returned a large sum of money to the owner.2 Did Chen return the money because she didn't need it?No. She returned the money because it was the right thing to do. Evidence for this is that she refused to accept the reward money because she felt that it had not been earned. 3 Is it common for people to do what Chen did?It depends on the culture. In some countries it is quite common to return money that has been found. In other countries, people believe "Finders are keepers!" 4 How did Wang Zheng feel about the return of his money?He must have been very happy and relieved to have gotten his money back. We know this because he thanked Chen repeatedly and even offered her a reward.5 Why did Ma Dongbao tell Wang about Chen's family?He must have had great sympathy for Chen and her daughter and wanted to help them.'We know this because he arranged help for them. 6 How did the news reporter feel about Chen's actions?The news reporter felt that it showed that money wasn't the most important thing in life. We know this because the reporter told us that this is what Chen believes. and then said, “that's a great attitude to take."

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、典例解析例4. 用 10 000元購買某個理財產(chǎn)品一年.(1)若以月利率0.400%的復(fù)利計息,12個月能獲得多少利息(精確到1元)?(2)若以季度復(fù)利計息,存4個季度,則當(dāng)每季度利率為多少時,按季結(jié)算的利息不少于按月結(jié)算的利息(精確到10^(-5))?分析:復(fù)利是指把前一期的利息與本金之和算作本金,再計算下一期的利息.所以若原始本金為a元,每期的利率為r ,則從第一期開始,各期的本利和a , a(1+r),a(1+r)^2…構(gòu)成等比數(shù)列.解:(1)設(shè)這筆錢存 n 個月以后的本利和組成一個數(shù)列{a_n },則{a_n }是等比數(shù)列,首項a_1=10^4 (1+0.400%),公比 q=1+0.400%,所以a_12=a_1 q^11 〖=10〗^4 (1+0.400%)^12≈10 490.7.所以,12個月后的利息為10 490.7-10^4≈491(元).解:(2)設(shè)季度利率為 r ,這筆錢存 n 個季度以后的本利和組成一個數(shù)列{b_n },則{b_n }也是一個等比數(shù)列,首項 b_1=10^4 (1+r),公比為1+r,于是 b_4=10^4 (1+r)^4.

二、典例解析例3.某公司購置了一臺價值為220萬元的設(shè)備,隨著設(shè)備在使用過程中老化,其價值會逐年減少.經(jīng)驗表明,每經(jīng)過一年其價值會減少d(d為正常數(shù))萬元.已知這臺設(shè)備的使用年限為10年,超過10年 ,它的價值將低于購進(jìn)價值的5%,設(shè)備將報廢.請確定d的范圍.分析:該設(shè)備使用n年后的價值構(gòu)成數(shù)列{an},由題意可知,an=an-1-d (n≥2). 即:an-an-1=-d.所以{an}為公差為-d的等差數(shù)列.10年之內(nèi)(含10年),該設(shè)備的價值不小于(220×5%=)11萬元;10年后,該設(shè)備的價值需小于11萬元.利用{an}的通項公式列不等式求解.解:設(shè)使用n年后,這臺設(shè)備的價值為an萬元,則可得數(shù)列{an}.由已知條件,得an=an-1-d(n≥2).所以數(shù)列{an}是一個公差為-d的等差數(shù)列.因為a1=220-d,所以an=220-d+(n-1)(-d)=220-nd. 由題意,得a10≥11,a11<11. 即:{█("220-10d≥11" @"220-11d<11" )┤解得19<d≤20.9所以,d的求值范圍為19<d≤20.9

環(huán)節(jié)四 課堂總結(jié) 鞏固知識本節(jié)課我采用線索性的板書,整個知識結(jié)構(gòu)一目了然,為了充分發(fā)揮學(xué)生在課堂的主體地位,我將課堂小結(jié)交由學(xué)生完成,請學(xué)生根據(jù)課堂學(xué)習(xí)的內(nèi)容,結(jié)合我的板書設(shè)計來進(jìn)行小結(jié),以此來幫助教師在第一時間掌握學(xué)生學(xué)習(xí)信息的反饋,同時培養(yǎng)學(xué)生歸納分析能力、概括能力。環(huán)節(jié)五 情景回歸,情感升華我的實習(xí)指導(dǎo)老師告訴過我們,政治這一門學(xué)科要從生活中來到生活去,所以在課堂的最后布置課外作業(yè),以此培養(yǎng)學(xué)生對理論的實際運用能力,同時檢驗他們對知識的真正掌握情況,以此達(dá)到情感的升華,本節(jié)課,我根據(jù)建構(gòu)主義理論,強調(diào)學(xué)生是學(xué)習(xí)的中心,學(xué)生是知識意義的主動建構(gòu)者,是信息加工的主體,要強調(diào)學(xué)生在課堂中的參與性、以及探究性,不僅讓他們懂得知識,更讓他們相信知識,并且將知識融入到實踐當(dāng)中去,最終達(dá)到知、情、意、行的統(tǒng)一。

教師點評:根據(jù)小論文的寫作情況對小論文給予肯定,同時指出其有待修改的地方。學(xué)生在寫小論文的時候是根據(jù)教材中的提示來寫的,所以對于教材中的這些提示,可以作一個說明。如“在發(fā)展的過程中,我們面對怎樣的挑戰(zhàn)和困難”,對于這點,學(xué)生可能會出現(xiàn)片面看問題的不足,一旦這種情況出現(xiàn),我們就要及時進(jìn)行說明:我們面臨的挑戰(zhàn)和困難既有來自國內(nèi)的,也有來自國際的,引導(dǎo)學(xué)生學(xué)會用全面的觀點分析問題。教師引導(dǎo)學(xué)生明確作為中學(xué)生可以從以下方面去作準(zhǔn)備:第一,要有國家觀念、民族意識,不斷增強民族自豪感、自尊心和自信心;第二,關(guān)注國家大事;第三,自自覺履行維護(hù)國家統(tǒng)一和民族團(tuán)結(jié)的義務(wù),維護(hù)國家安全、榮譽和利益;第四,努力學(xué)好科學(xué)文化知識,提高自己的科學(xué)文化素質(zhì)和思想道德素質(zhì),增強各個方面的能力,掌握振興中華民族的本領(lǐng),這也是中學(xué)生最需要做到的。通過探究活動,培養(yǎng)學(xué)生獲取信息的能力,自主學(xué)習(xí)的能力以及全面看問題的能力,再結(jié)合教師的講授,給學(xué)生一種茅塞頓開的感覺。

教學(xué)過程:(一)導(dǎo)入:課前放《愛的奉獻(xiàn)》歌曲,同時不斷播放一些有關(guān)“愛”的主題的圖片,渲染一種情感氛圍。師說:同學(xué)們,誰能說說這組圖片的主題應(yīng)該是什么?生(七嘴八舌):母愛,不對是親情……是友情、還有人與人互相幫助……那組軍人圖片是說保衛(wèi)國家,應(yīng)該是愛國……那徐本禹和感動中國呢?…………生答:是關(guān)于愛的方面師說:不錯,是關(guān)于愛的方面。那么同學(xué)們,今天就以“愛的奉獻(xiàn)”為話題,來寫一篇議論文如何?生答:老師,還是寫記敘文吧。生答:就是,要不議論文寫出來也象記敘文。師問:為什么?生答:老師,這個話題太有話說了,一舉例子就收不住了,怎么看怎么象記敘文。生答:就是,再用一點形容詞,就更象了。眾人樂。師說:那么同學(xué)們誰能告訴我,為什么會出現(xiàn)這種問題?一生小聲說:還不是我們笨,不會寫。師說:不是笨,也不是不會寫,你們想為什么記敘文就會寫,一到議論文就不會了,那是因為同學(xué)們沒有明白議論文中的記敘與記敘文中的記敘有什么不同,所以一寫起議論文中的記敘,還是按照記敘文的寫法寫作,這自然就不行了。那好,今天我們就從如何寫議論文中的記敘講起。

一、說教材(一)、教材內(nèi)容《古代中國的發(fā)明和發(fā)現(xiàn)》是人教版高中歷史必修三第三單元第一課內(nèi)容,本課教材主要從五個方面的典型事例向?qū)W生介紹了古代中國幾千年的科技成就。本課一方面展示了古代中國人民的勤勞智慧以及對世界文明發(fā)展作出的巨大貢獻(xiàn),另一方面也提出了一個重大問題引起學(xué)生的思考,即造成中國科技在近代落后的原因是什么。此外、本課在教材中具有承上啟下的地位和作用,前承中國傳統(tǒng)文化主流思想,后啟現(xiàn)代中國科學(xué)技術(shù)的發(fā)展。根據(jù)課標(biāo)要求和教材內(nèi)容,我將本課的三維目標(biāo)確定如下:(三)教學(xué)目標(biāo)(1)知識與能力:掌握中國古代科技進(jìn)步的基礎(chǔ)知識,特別是四大發(fā)明。認(rèn)識古代中國四大發(fā)明對世界文明發(fā)展的貢獻(xiàn),以及取得重大成就的原因。⑵過程與方法:通過指導(dǎo)學(xué)生課前閱讀課本,在課堂上進(jìn)行問題探究、實驗體驗以及歷史比較,學(xué)會總結(jié)歸納。

3、評:以評促行。(6分鐘)高中生的年齡特點決定了他們非常重視別人對自己的評價,渴望得到他人的肯定與鼓勵。(所以我在班上組織一個活動:讓同學(xué)們評選出班上“講文明懂禮貌的文明之星”、“勤思考善創(chuàng)新的學(xué)習(xí)之星”(先讓同學(xué)推舉大家都認(rèn)同的4位同學(xué),然后對他們進(jìn)行投票,投票結(jié)果將在下堂課上公布)以此活動來激發(fā)同學(xué)們用實際行動做民族精神的踐行者和傳播者。)4、唱:以情激行。(2分鐘)在課程內(nèi)容講授結(jié)完畢后,組織全班同學(xué)跟著音樂高唱孫楠的《紅旗飄飄》,生化情感,激發(fā)同學(xué)們的愛國情感。五、課堂拓展(請同學(xué)們各展才華:課后讓同學(xué)們各自準(zhǔn)備一個項目以體現(xiàn)民族精神。(項目形式是:或作文、書畫;或剪紙、或歌曲小品)……讓同學(xué)們用實際行動祝愿我們偉大的祖國更加繁榮昌盛!讓我們的民族精神代代相傳?。?/p>
