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.

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

點撥：旅游地旅游資源的特色不同，可以安排的旅游活動是不一樣的，直接影響對旅游者的吸引力。因此，出游前首先就需要收集旅游地旅游資源的類型、主要游覽景區(qū)、景點的特色等情況。旅游地的時空可達性直接關系到旅游者從出發(fā)地到旅游地，然后再返回出發(fā)地的費用和時間。一般來說，居住地與旅游地之間的空間距離過大，會使旅行的時間過長、旅行費用過高，經濟距離增加，相應地降低了旅游者的出游能力。而居住地與旅游地相距遙遠，也意味著兩地之間巨大的環(huán)境差異，這會增加對游客的吸引力。旅游服務設施和條件，如旅游交通方式及工具、旅游住宿條件、旅游餐飲的種類和標準、導游服務、旅行費用等信息也都在一定程度上影響著游客的選擇。圖5．3西藏布達拉宮和圖5．4云南香格里拉兩幅圖片顯示了西藏布達拉宮、云南香格里拉與眾不同的優(yōu)美景觀，吸引了眾多的游客前來觀光旅游，成為近年來國內旅游的熱點。

本節(jié)課選自《普通高中課程標準數(shù)學教科書-必修一》（人教A版）第三章《函數(shù)的概念與性質》，本節(jié)課是第2課時，本節(jié)課主要學習函數(shù)的三種表示方法及其簡單應用，進一步加深對函數(shù)概念的理解。課本從引進函數(shù)概念開始就比較注重函數(shù)的不同表示方法：解析法，圖象法，列表法．函數(shù)的不同表示方法能豐富對函數(shù)的認識，幫助理解抽象的函數(shù)概念．特別是在信息技術環(huán)境下，可以使函數(shù)在形與數(shù)兩方面的結合得到更充分的表現(xiàn)，使學生通過函數(shù)的學習更好地體會數(shù)形結合這種重要的數(shù)學思想方法．因此，在研究函數(shù)時，要充分發(fā)揮圖象的直觀作用．課程目標 學科素養(yǎng)A.在實際情景中，會根據不同的需要選擇恰當?shù)姆椒ǎń馕鍪椒?、圖象法、列表法）表示函數(shù)；B.了解簡單的分段函數(shù)，并能簡單地應用；1.數(shù)學抽象：函數(shù)解析法及能由條件求函數(shù)的解析式；2.邏輯推理：求函數(shù)的解析式；

課本從引進函數(shù)概念開始就比較注重函數(shù)的不同表示方法：解析法，圖象法，列表法．函數(shù)的不同表示方法能豐富對函數(shù)的認識，幫助理解抽象的函數(shù)概念．特別是在信息技術環(huán)境下，可以使函數(shù)在形與數(shù)兩方面的結合得到更充分的表現(xiàn)，使學生通過函數(shù)的學習更好地體會數(shù)形結合這種重要的數(shù)學思想方法．因此，在研究函數(shù)時，要充分發(fā)揮圖象的直觀作用．在研究圖象時，又要注意代數(shù)刻畫以求思考和表述的精確性．課本將映射作為函數(shù)的一種推廣，這與傳統(tǒng)的處理方式有了邏輯順序上的變化．這樣處理，主要是想較好地銜接初中的學習，讓學生將更多的精力集中理解函數(shù)的概念，同時，也體現(xiàn)了從特殊到一般的思維過程．課程目標1、明確函數(shù)的三種表示方法；2、在實際情境中，會根據不同的需要選擇恰當?shù)姆椒ū硎竞瘮?shù)；3、通過具體實例，了解簡單的分段函數(shù)，并能簡單應用.
