新人教版高中英語(yǔ)必修3Unit 1 Festivals and Celebrations-Listening &Speaking＆Talking教學(xué)設(shè)計(jì)
The theme of this section is “Talk about festival activities and festival experiences”.Festival and holiday is a relaxing and interesting topic for students. This part talks about the topic from the daily life of students’. In the part A ---Listening and Speaking, there are three conversations among different speakers from three countries(Japan, Rio and China), where the speakers are participating in or going to participate in the festivals and celebrations. So listening for the relationship among them is a fundamental task. Actually, with the globalization and more international communication, it is normal for Chinese or foreigners to witness different festivals and celebrations in or out of China. In the Conversation 1, a foreign reporter is interviewing a Japanese young girl who just had participated in the ceremony of the Coming-of-Age Day on the street and asking her feeling about the ceremony and the afterwards activities. Conversation 2, Chinese girl Li Mei is witnessing the Rio Carnival for the first time, and her friend Carla gives her some advice on the costumes which enables her to match with the carnival to have a good time. Conversation 3, a Chinese guide is showing a group of foreign visitors around the Lantern Festival and introducing the customs of the festival to them. The three conversations have a strong vitality and insert the festival and cultural elements from different countries. So perceiving the festivals and cultures from different countries is the second task. At the same time, the scripts also insert the targeted grammar --- v-ing as attributive and predicative, which students can perceive and experience in a real context and make a road for the further study. That is the third task. In the Part B--- Listening and Talking, the theme is “Talk about festival experience”, which is the common topic in our daily conversations. During the conversation, Song Lin, a Chinese student, asked Canadian friend Max about how to spend Christmas. In the conversation, Song Lin talked about experience and the feelings during the Chinese Spring Festival, during which there are not only some enjoyable things but some unpleasant things. After the listening, perhaps students find there are some similarities between Christmas and the Chinese Spring Festival as there are some differences in the origins and celebrations. For example, people always visit friends and relatives, decorate their houses, have a big dinner together, chat and give presents to each other.

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(lái), 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？

He decides to have it cut. )H=Henry B=BarberH: Good afternoon, I’d like to have my hair cut, if I may. (The barber looks at Henry’s hair and continues cutting another man’s hair. ) Er, I’d really like a haircut. As you can see it’s much too long. B: (in a rude manner) Yes, I can see that. Indeed, I can. H: Fine, well, I’ll have a seat then. (He sits in one of the barber’s chairs. The barber turns to look at Henry. )B: It’s quite expensive here, you know!

新知探究前面我們研究了兩類變化率問(wèn)題：一類是物理學(xué)中的問(wèn)題，涉及平均速度和瞬時(shí)速度；另一類是幾何學(xué)中的問(wèn)題，涉及割線斜率和切線斜率。這兩類問(wèn)題來(lái)自不同的學(xué)科領(lǐng)域，但在解決問(wèn)題時(shí)，都采用了由“平均變化率”逼近“瞬時(shí)變化率”的思想方法；問(wèn)題的答案也是一樣的表示形式。下面我們用上述思想方法研究更一般的問(wèn)題。探究1： 對(duì)于函數(shù)y=f(x) ，設(shè)自變量x從x_0變化到x_0+ ?x ，相應(yīng)地，函數(shù)值y就從f(x_0)變化到f(〖x+x〗_0) 。這時(shí)， x的變化量為?x，y的變化量為?y=f(x_0+?x)-f(x_0)我們把比值?y/?x，即?y/?x=(f(x_0+?x)-f(x_0)" " )/?x叫做函數(shù)從x_0到x_0+?x的平均變化率。1．導(dǎo)數(shù)的概念如果當(dāng)Δx→0時(shí)，平均變化率ΔyΔx無(wú)限趨近于一個(gè)確定的值，即ΔyΔx有極限，則稱y＝f (x)在x＝x0處____，并把這個(gè)________叫做y＝f (x)在x＝x0處的導(dǎo)數(shù)(也稱為_(kāi)_________)，記作f ′(x0)或________，即

二、典例解析例4. 用 10 000元購(gòu)買某個(gè)理財(cái)產(chǎn)品一年.（1）若以月利率0.400%的復(fù)利計(jì)息，12個(gè)月能獲得多少利息（精確到1元）？（2）若以季度復(fù)利計(jì)息，存4個(gè)季度，則當(dāng)每季度利率為多少時(shí)，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(jì)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(kāi)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(gè)月以后的本利和組成一個(gè)數(shù)列{a_n }，則{a_n }是等比數(shù)列，首項(xiàng)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(gè)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(gè)季度以后的本利和組成一個(gè)數(shù)列{b_n }，則{b_n }也是一個(gè)等比數(shù)列，首項(xiàng) 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(gòu)置了一臺(tái)價(jià)值為220萬(wàn)元的設(shè)備，隨著設(shè)備在使用過(guò)程中老化，其價(jià)值會(huì)逐年減少.經(jīng)驗(yàn)表明，每經(jīng)過(guò)一年其價(jià)值會(huì)減少d(d為正常數(shù)）萬(wàn)元.已知這臺(tái)設(shè)備的使用年限為10年，超過(guò)10年 ，它的價(jià)值將低于購(gòu)進(jìn)價(jià)值的5%，設(shè)備將報(bào)廢.請(qǐng)確定d的范圍.分析：該設(shè)備使用n年后的價(jià)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(jià)值不小于（220×5%=）11萬(wàn)元；10年后，該設(shè)備的價(jià)值需小于11萬(wàn)元．利用{an}的通項(xiàng)公式列不等式求解．解：設(shè)使用n年后，這臺(tái)設(shè)備的價(jià)值為an萬(wàn)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(gè)公差為－d的等差數(shù)列.因?yàn)閍1＝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
