新人教版高中英語必修3Unit 4 Space Exploration-Listening&Speaking＆Talking教學設計二
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

人教版高中地理選修3第五章第一節(jié)設計旅游活動教案
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。

1. 完成文本主要信息填空（斜體字部分設空）：As a witness to farmers’ poor harvests and even a severe shortage of food, Yuan Longping was determined to devote his life to tackling this crisis. After graduation, he realized that what farmers needed most was to boost yields in the fields. Yuan was convinced that the answer lay in the creation of hybrid rice, one characteristic of which is that it usually achieve higher output than conventional crops. However, it was no easy job. The first difficulty he needed to overcome was scientists’ general assumption that this could not be done. Through trial and error, Yuan managed to generate this incredible crop. It is estimated that about 60 percent of domestic rice consumption in China was comprised of crops generated from Yuan’s hybrid strains. His innovation has enabled Chinese farmers to considerably expand their output and helped feed the world. Unwilling to retire early to a life of leisure and unconcerned about celebrity or fortune, Yuan continues to turn one vision after another into realities.2. 模仿寫作：Do some research via the Internet and introduce another agricultural scientist, Chen Risheng（陳日勝）, using the structure, expressions and writing techniques you have learnt from the text “A Pioneer for All People”.【設計意圖】任務1是對文本內容和詞匯學習成效的檢測。任務2借助文本中學到的詞匯和寫作手法仿寫另一位科學家，提升學生遷移運用詞匯、文體結構和寫作方法的能力。

二、典例解析例3.某公司購置了一臺價值為220萬元的設備，隨著設備在使用過程中老化，其價值會逐年減少.經驗表明，每經過一年其價值會減少d(d為正常數）萬元.已知這臺設備的使用年限為10年，超過10年 ，它的價值將低于購進價值的5%，設備將報廢.請確定d的范圍.分析：該設備使用n年后的價值構成數列{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的等差數列.10年之內（含10年），該設備的價值不小于（220×5%=）11萬元；10年后，該設備的價值需小于11萬元．利用{an}的通項公式列不等式求解．解：設使用n年后，這臺設備的價值為an萬元，則可得數列{an}．由已知條件，得an＝an－1－d（n≥2）．所以數列{an}是一個公差為－d的等差數列.因為a1＝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

(1) 求從正方形ABCD 開始，連續(xù)10個正方形的面積之和；(2) 如果這個作圖過程可以一直繼續(xù)下去，那么所有這些正方形的面積之和將趨近于多少？分析：可以利用數列表示各正方形的面積，根據條件可知，這是一個等比數列。解：設正方形的面積為a_1，后續(xù)各正方形的面積依次為a_2, a_(3, ) 〖…,a〗_n,…，則a_1=25,由于第k+1個正方形的頂點分別是第k個正方形各邊的中點，所以a_(k+1)=〖1/2 a〗_k,因此{a_n}，是以25為首項，1/2為公比的等比數列.設{a_n}的前項和為S_n（1）S_10=(25×[1-(1/2)^10 ] )/("1 " -1/2)=50×[1-(1/2)^10 ]=25575/512所以，前10個正方形的面積之和為25575/512cm^2.(2)當無限增大時，無限趨近于所有正方形的面積和

二、典例解析例4. 用 10 000元購買某個理財產品一年.（1）若以月利率0.400%的復利計息，12個月能獲得多少利息（精確到1元）？（2）若以季度復利計息，存4個季度，則當每季度利率為多少時，按季結算的利息不少于按月結算的利息（精確到10^(-5)）？分析：復利是指把前一期的利息與本金之和算作本金，再計算下一期的利息.所以若原始本金為a元，每期的利率為r ，則從第一期開始，各期的本利和a , a(1+r)，a(1+r)^2…構成等比數列.解：（1）設這筆錢存 n 個月以后的本利和組成一個數列{a_n }，則{a_n }是等比數列，首項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個月后的利息為10 490.7-10^4≈491（元）.解：（2）設季度利率為 r ，這筆錢存 n 個季度以后的本利和組成一個數列{b_n }，則{b_n }也是一個等比數列，首項 b_1=10^4 (1+r)，公比為1+r，于是 b_4=10^4 (1+r)^4.
