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. 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？

二、探究交流，引導(dǎo)概括 —— 方程為了培養(yǎng)學(xué)生的發(fā)現(xiàn)和抽象概括能力，同時進(jìn)一步理解方程的意義，我讓學(xué)生分組學(xué)習(xí)，引導(dǎo)他們先找出②20+χ=100，⑥ 3χ=180，⑧100+2χ=3×50像上面三臄?shù)仁降挠泄餐卣?，然后歸納概括什么叫做方程？最后得出：像這樣的含有未知數(shù)的等式，叫做方程。三、討論比較，辨析、概念 —— 等式與方程的關(guān)系為了體現(xiàn)學(xué)生的主體性，培養(yǎng)學(xué)生的合作意識，同時讓學(xué)生在解決問題的過程中得到創(chuàng)造的樂趣。通過四人合作用自己的方法創(chuàng)作 “ 方程 ” 與 “ 等式 ” 的關(guān)系圖，并用自己的話說一說 “ 等式 ” 與 “ 方程 ” 的關(guān)系：方程一定是等式，但等式不一定是方程。四、鞏固深化，拓展思維 —— 練習(xí)1 、“做一做”：2、判斷是否方程3、“方程一定是等式，等式也一定是方程”這句話對嗎？4、叫學(xué)生用圖來表示等式和方程的關(guān)系。

創(chuàng)設(shè)情境，導(dǎo)入新課：你對母親知多少師問1：我們5月份剛過了一個重要的節(jié)日，你知道是什么嗎？----母親節(jié)。師問2：那你知道媽媽的生日嗎？（舉手示意），每個媽媽都知道自己孩子的生日，請不知道的同學(xué)回家了解一下，多關(guān)心一下自己的父母。師問3：那你知道媽媽最愛吃的菜嗎？你可以選擇知道、不知道或者是沒有愛吃的（拖動白板上相對應(yīng)的表情符號）。請大家用不同的手勢表示出來。我找3名同學(xué)統(tǒng)計(jì)各組的數(shù)據(jù)，寫在黑板上（隨機(jī)找3名學(xué)生數(shù)人數(shù)）。下面我來隨機(jī)采訪一下：你媽媽最喜歡吃的菜是什么？（教師隨機(jī)采訪，結(jié)合營養(yǎng)搭配和感恩教育）

二、說教學(xué)目標(biāo)知識與技能：初步理解“方程的解”和“解方程”的含義，以及之間的聯(lián)系和區(qū)別。能用等式的性質(zhì)解形如X±a=b的方程，掌握解方程的格式和寫法。初步學(xué)會檢驗(yàn)?zāi)硞€數(shù)是否是方程的解，培養(yǎng)學(xué)生檢驗(yàn)的習(xí)慣，提高計(jì)算能力。過程和方法：通過探索、討論、交流等活動，讓學(xué)生初步理解“方程的解”和“解方程”的概念。經(jīng)歷運(yùn)用等式的性質(zhì)探究方程解法的過程，體會方程的解法和等式的性質(zhì)之間的聯(lián)系。情感、態(tài)度與價值觀：1. 學(xué)生能積極參與數(shù)學(xué)學(xué)習(xí)活動，對數(shù)學(xué)有好奇心和求知欲。2. 在觀察、猜想、驗(yàn)證等數(shù)學(xué)活動中，培養(yǎng)學(xué)生的數(shù)學(xué)素養(yǎng)。重點(diǎn)：方程的解和解方程的概念，初步掌握用等式性質(zhì)來解簡易方程的方法。難點(diǎn)：區(qū)別方程的解和解方程的含義。解方程的算理。三、說教法與學(xué)法教法：新課標(biāo)指出，教師是學(xué)習(xí)的組織者、引導(dǎo)者、合作者，充分發(fā)揮學(xué)生的主體性。根據(jù)這一理念，我在教學(xué)中通過觀察、猜想、驗(yàn)證等方式，自主探索、自主學(xué)習(xí)。有目的地運(yùn)用知識遷移的規(guī)律，引導(dǎo)學(xué)生進(jìn)行觀察、比較、分析、概括，培養(yǎng)學(xué)生的邏輯思維能力。學(xué)法：①讓學(xué)生學(xué)會以舊引新，掌握并運(yùn)用知識遷移進(jìn)行學(xué)習(xí)的方法；②讓學(xué)生學(xué)會自主發(fā)現(xiàn)問題，分析問題，解決問題的方法。
