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.

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.

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.

2、教學(xué)目標(biāo)根據(jù)我對(duì)教材的理解、結(jié)合學(xué)生的實(shí)際情況、滲透新課程的教學(xué)理念，為提高全體學(xué)生的科學(xué)素養(yǎng)，按課程標(biāo)準(zhǔn)，以促進(jìn)全體學(xué)生發(fā)展為目的。從知識(shí)與技能、過程與方法，情感態(tài)度與價(jià)值觀三個(gè)方向培養(yǎng)學(xué)生，擬定三個(gè)教學(xué)目標(biāo)：知識(shí)與技能：（1）知道什么是動(dòng)能。（2）正確理解和運(yùn)用動(dòng)能公式分析、解答有關(guān)問題。（3）掌握外力對(duì)物體所做的總功的計(jì)算，理解“代數(shù)和”的含義。（4）理解和運(yùn)用動(dòng)能定理。過程與方法：通過演繹推理過程，培養(yǎng)科學(xué)研究興趣，領(lǐng)略物理學(xué)中所蘊(yùn)含的嚴(yán)謹(jǐn)?shù)倪壿嬯P(guān)系。情感、態(tài)度、價(jià)值觀：通過運(yùn)用動(dòng)能定理分析解決問題，感受成功的喜悅，培養(yǎng)學(xué)生對(duì)科學(xué)研究的興趣。3、教學(xué)的重點(diǎn)和難點(diǎn)重點(diǎn)：理解動(dòng)能定理、應(yīng)用動(dòng)能定理解決力學(xué)問題。難點(diǎn)：應(yīng)用動(dòng)能定理解決多個(gè)過程的力學(xué)問題，以及變力做功或曲線運(yùn)動(dòng)中的動(dòng)能定理運(yùn)用。

（5）高度不同，對(duì)平拋運(yùn)動(dòng)距離有何影響，是否因?yàn)楦叨葴p小后下落時(shí)間減小，所以要增大速度才能達(dá)到相同的距離？（教學(xué)實(shí)踐證明，這種想法在學(xué)生比較多見。已經(jīng)不自覺的沿用了自由落體運(yùn)動(dòng)的規(guī)律，又隱隱有運(yùn)動(dòng)等時(shí)性的痕跡。應(yīng)引導(dǎo)學(xué)生這一結(jié)果還需實(shí)驗(yàn)驗(yàn)證。）教師的引導(dǎo)：其實(shí)，我們所提出的看法都跟平拋運(yùn)動(dòng)的規(guī)律有關(guān)系。那么平拋運(yùn)動(dòng)究竟有怎樣的規(guī)律呢？以前學(xué)過的直線運(yùn)動(dòng)知識(shí)還能用于今天的內(nèi)容嗎？由此逐步使學(xué)生意識(shí)到分析平拋運(yùn)動(dòng)須采用運(yùn)動(dòng)合成與分解這一方法。三、實(shí)驗(yàn)驗(yàn)證自主探究（15分鐘） 物理是實(shí)驗(yàn)科學(xué)，多媒體教學(xué)不能代替實(shí)驗(yàn)。本教學(xué)設(shè)計(jì)的第三個(gè)環(huán)節(jié)是實(shí)驗(yàn)驗(yàn)證，鼓勵(lì)學(xué)生自主探究。引導(dǎo)學(xué)生根據(jù)自己的猜想（實(shí)驗(yàn)?zāi)康模┰O(shè)計(jì)實(shí)驗(yàn)進(jìn)行驗(yàn)證。（1）介紹手持式平拋豎落儀，引導(dǎo)并小結(jié)實(shí)驗(yàn)要領(lǐng)：聽兩小球下落聲音判斷其下落時(shí)間。體會(huì)合運(yùn)動(dòng)和分運(yùn)動(dòng)是等時(shí)的。
