Word map construction Show students a video about humans landing on the moon, and ask students to say out the things they see. Help students to answer: astronauts, spacecraft, the moon and so on. Then ask students to work in groups of four. Try to think out more related words like: earth, scientists, stars, space shuttle, sun, planet, universe, space station, air, space and so on.astronautspacecraft (設(shè)計(jì)說(shuō)明:這個(gè)環(huán)節(jié)的設(shè)置旨在培養(yǎng)學(xué)生的自主學(xué)習(xí)、合作學(xué)習(xí)與發(fā)散思維的能力。學(xué)生在觀看錄像之后,說(shuō)出已知的單詞,并嘗試聯(lián)想相關(guān)詞匯,這有利于學(xué)生發(fā)散思維能力的培養(yǎng)。若涉及未學(xué)過(guò)的詞匯,學(xué)生可以通過(guò)小組互助合作查找出來(lái),改變了由老師教,學(xué)生學(xué)的傳統(tǒng)的單詞教學(xué)的模式。學(xué)生通過(guò)合作探究,自學(xué)新的知識(shí),若在反饋中出現(xiàn)錯(cuò)誤,老師可適當(dāng)糾正。這些都為下面的聽(tīng)力環(huán)節(jié)解決了語(yǔ)言上可能出現(xiàn)的困難。)2. Ask students to answer some questions about this video. How did the astronauts go to the moon?. How many spacecrafts has America sent to the moon by now?. Have they discovered life on the moon?. Have the scientists sent spacecrafts to Mars yet?. Have they discovered life on Mars yet?設(shè)計(jì)說(shuō)明:此環(huán)節(jié)可以幫助學(xué)生更深入地了解人類登月的歷史。最后的兩個(gè)問(wèn)題,很自然的將討論的話題由登月過(guò)渡到火星探索方面,由此引出了接下來(lái)的內(nèi)容,起到承上啟下的銜接作用。另外,這些問(wèn)題的設(shè)置很自然的引出該堂課的重點(diǎn)句型:Have they yet? Yes, they have just / already. No, not yet. / No, they havent yet.)Step 2 Listening (Activities 1 & 2)1. Tell students to listen to a piece of news about the travel mission to Mars and find the answer to the question “Have they discovered life on Mars yet?” and finish Activity 1: Listen and number the words as you hear them.2. Listen again and finish Activity 2: Check the true sentences.(設(shè)計(jì)說(shuō)明:本活動(dòng)為聽(tīng)力基本能力訓(xùn)練,是一種聽(tīng)力輸入理解活動(dòng)。聽(tīng)力的相關(guān)內(nèi)容對(duì)火星探索計(jì)劃作了簡(jiǎn)單的介紹,為學(xué)生能更好的理解下一環(huán)節(jié)中的對(duì)話內(nèi)容作了鋪墊。)Step 3 Listening and reading (Activities 3, 4, 5)1. Tell students Da Mings friend Tony has made a model of a space station, and now they are talking about the model. Ask students to listen and read the dialogues, then try to answer three questions: . Has the spacecraft to Mars arrived yet? . Have many astronauts been to the moon recently? . How do the astronauts go back to the earth from the space station?2. Ask students to read the dialogue again and finish Activities 4 and 5.3. Students read after the tape and then act out the dialogue.(設(shè)計(jì)說(shuō)明:通過(guò)這一環(huán)節(jié)的學(xué)習(xí),學(xué)生們對(duì)火星探索計(jì)劃的了解更為透徹了。而朗讀與表演對(duì)話則能使教學(xué)內(nèi)容得到進(jìn)一步的鞏固與提高。)Step 4 Tasks (Activity 6)1. Show students a video and some pictures of space stations, and introduce the basic structures of a space station. Then ask students to discuss in groups of four to find the differences between the life on earth and the life at a space station. They may use “We can but we cant.”(設(shè)計(jì)說(shuō)明:這個(gè)活動(dòng)為學(xué)生展開(kāi)豐富的想象提供了充分的空間,同時(shí),還兼顧了學(xué)科之間的滲透。學(xué)生可以利用已掌握的科學(xué)知識(shí),大膽地想象,甚至可以提供創(chuàng)造性的答案。這都有利于學(xué)生邏輯思維能力與創(chuàng)新能力的培養(yǎng)。另外,這個(gè)活動(dòng)還為下一活動(dòng)的開(kāi)展作了較好的鋪墊。)2. Information gap Ask students to suppose: one of the classmates is an astronaut in a space station, now he is talking to his son / daughter through TV about what they two have done recently. Then tell students to work in pairs and finish the sheets. (表格見(jiàn)附錄 Page7,Page8 )(設(shè)計(jì)說(shuō)明:在這個(gè)環(huán)節(jié)中,通過(guò)創(chuàng)設(shè)信息差,吸引學(xué)生積極參與課堂活動(dòng)。在傳統(tǒng)的教學(xué)模式中,我們常用生生之間一問(wèn)一答的方式,操練與鞏固句型。但由于缺乏特定的情境,這樣的活動(dòng)只操練句型,而忽略意義,無(wú)法調(diào)動(dòng)學(xué)生的興趣。而信息差的創(chuàng)設(shè)可以使原有的活動(dòng)變得有意義。學(xué)生必須使用目標(biāo)語(yǔ)言來(lái)獲得想要的信息,實(shí)現(xiàn)了“用英語(yǔ)做事情”這一教學(xué)基本目標(biāo)。)Step 5 Writing petition (Activities 8 & 9)Show students the photos of Chinese famous astronauts Yang Liwei, Fei Junlong and Nie Haishen. Ask students to talk in groups of four about what we Chinese have already done about the space travel and what we havent done yet. First, students work by themselves in three minutes, then share his / her ideas with the workmates in three minutes, finally the groups show their ideas before the whole class. The one who has the longest list will win the petition.(設(shè)計(jì)說(shuō)明:本環(huán)節(jié)的活動(dòng)是上一環(huán)節(jié)活動(dòng)的延續(xù)。以航空為話題強(qiáng)化學(xué)生對(duì)現(xiàn)在完成時(shí)的運(yùn)用能力。在活動(dòng)中將學(xué)生自主學(xué)習(xí)與小組合作活動(dòng)相結(jié)合,旨在培養(yǎng)學(xué)生獨(dú)立自主的學(xué)習(xí)能力及分享觀點(diǎn),相互協(xié)作的能力。)Step 6 Homework1.

Then plete the following questionnaire.-What have you done recently?-I have made a poster about space travel.NameTimeSomething special that you have donerecentlythis weekin the past few weeks3. Making a reportStudents make a short report with the questionnaire.(設(shè)計(jì)說(shuō)明:這一環(huán)節(jié)是一個(gè)熱身活動(dòng),通過(guò)師生的日常問(wèn)答,復(fù)習(xí)了上節(jié)課的主要知識(shí)結(jié)構(gòu)。在生生之間的對(duì)話操練環(huán)節(jié),通過(guò)設(shè)計(jì)一個(gè)調(diào)查活動(dòng),把合作活動(dòng)設(shè)置在具體、真實(shí)、自然的情景中,貼近了學(xué)生的生活,這樣能更好地激發(fā)學(xué)生的興趣,吸引更多的學(xué)生主動(dòng)、積極地參與教學(xué)活動(dòng)。)Step 2 Pre-reading1. Teach students the solar system, then ask them to look at the picture of the solar system on the blackboard. Tell them to put the nine planets at the right place.(制作九大行星的教具)(設(shè)計(jì)說(shuō)明:通過(guò)這個(gè)游戲活動(dòng),將較難掌握的天體名稱以生動(dòng)有趣的形式呈現(xiàn)給學(xué)生,可以活躍課堂氣氛,提高學(xué)生的興趣。學(xué)生在愉悅的氛圍中學(xué)習(xí)知識(shí),能達(dá)到良好的教學(xué)效果。)2. Ask students to work in groups of four and discuss two questions: Have we found life on other eight planets yet? If not, why? What do you know about UFO? Do you believe there are creatures from outer space? Why or why not?(設(shè)計(jì)說(shuō)明:通過(guò)對(duì)這兩個(gè)問(wèn)題的分組討論,使學(xué)生對(duì)所要了解的閱讀材料的相關(guān)背景知識(shí)有一個(gè)感性認(rèn)識(shí),減少閱讀障礙,為學(xué)生理解閱讀材料打下良好的基礎(chǔ)。)Step 3 Reading (Activities 2 & 3)1. Global reading (Activity 2) Students read the article and try to find the title of the article. (First students choose the title by themselves, then discuss it with their partners. They must try to explain the reasons.)(設(shè)計(jì)說(shuō)明:訓(xùn)練學(xué)生的整體理解能力。反饋是要求學(xué)生說(shuō)明選擇的依據(jù),目的是幫助學(xué)生分析細(xì)節(jié)與整體的差別,關(guān)注學(xué)生閱讀策略的培養(yǎng)。)2. Detailed reading (Activities 3 & 4) Students read the article again and finish Activities 3 and 4. (First students do by themselves, then share the answers with their partners.)(設(shè)計(jì)說(shuō)明:就閱讀理解而言,輸出與輸入同樣重要,因此有必要加強(qiáng)輸出性的活動(dòng)。本環(huán)節(jié)所涉及的技能不只是細(xì)節(jié)的理解與判斷,同時(shí)還有歸納、推理與邏輯。因此,在此環(huán)節(jié)中,要求學(xué)生先獨(dú)立思考,完成練習(xí);然后分享討論結(jié)果,總結(jié)閱讀技巧與規(guī)律。)3. Problem solving. Students work in groups of four again, trying to find difficulties in the article and discuss together. At the same time, discuss some language points raised by partners. If there is any problem, they may ask the teacher for help. At last share their worksheets with the whole class.NameLanguage pointsDifficultiesSolutions(設(shè)計(jì)說(shuō)明:在傳統(tǒng)的教學(xué)中,老師總是充當(dāng)主角,羅列出課文的重點(diǎn)、難點(diǎn)進(jìn)行講解,學(xué)生只有被動(dòng)的接受,學(xué)習(xí)主動(dòng)性受到很大的限制。設(shè)計(jì)這個(gè)環(huán)節(jié)是為了幫助學(xué)生提高學(xué)習(xí)的主動(dòng)性,學(xué)會(huì)自主學(xué)習(xí)的方法,逐漸形成比較完善的閱讀學(xué)習(xí)策略。)Step 4 Discussion and making a science reportTell students that because of the pollution, the environment on earth is being worse and worse. If one day, humans cant live on earth any more, they have to find “a second earth” in space for them to live on, what kind of planet is suitable? Ask students to discuss in groups of four and make a report.(設(shè)計(jì)說(shuō)明:將課內(nèi)閱讀延伸到課外,是對(duì)課內(nèi)學(xué)習(xí)的補(bǔ)充和拓展。讓學(xué)生在探究中得到提高,這有利于學(xué)生綜合素質(zhì)能力的培養(yǎng)。)Step 5 Writing (Activities 6 & 7)Show students a cartoon picture, asking them to answer the questions first, then use the answers to write the story in the cartoon picture.(設(shè)計(jì)說(shuō)明:本環(huán)節(jié)分為兩個(gè)步驟。第一步是句子寫(xiě)作,第二步是語(yǔ)篇寫(xiě)作。第一步為第二步作好準(zhǔn)備,這種遞進(jìn)的方式對(duì)于英語(yǔ)基礎(chǔ)不好的學(xué)生尤為有用。在了解了有關(guān)航天知識(shí),基本掌握了現(xiàn)在完成時(shí)的用法后,借助卡通圖片對(duì)人類探索火星進(jìn)行描述,能夠?qū)⑺鶎W(xué)知識(shí)進(jìn)一步鞏固和強(qiáng)化。)Step 6 Homework 1.
