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.

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.

Everybody wants to get wealth.In today’s material world,making money or becoming wealthy symbolizes a person’s success and capability. Many people just make every effort, pay any price to attain greater wealth. With money,they can buy nice, large apartments in nice neighborhood. With money they can own luxurious cars. Wealth seems to bring all happiness in life.But is wealth the only road to happiness? Not really. There are many things in the world, which are beyond the means of money, such as friendship, love, health and knowledge. People are so preoccupied with struggling for money that they have no time or would not take the time to form or maintain friendship. What happiness can they feel living as lonely miserable creatures without love or friends in the world even if they accumulate tremendous wealth?In my opinion, people can’t do anything without money, but money is not everything. What money will bring you depends on your personal belief and goal in life. If you are kind enough to help others, especially the poor, money is a good thing to you. With it, you can do much more for the benefit of people and your country, and it will add to your own happiness. If you want money just for your own needs, you’ll never be satisfied or happy. In a word,you should have money spent for more people. Only then can money be the source of your happiness.Step 8 Homework4 students in a group, one acts Roderick, one Oliver, one servant and the fourth one acts Henry Adams, then listen to the tape, pay more attention to the difference between American English and British English in pronunciation, stress, tone.

(1)下面列出的是我國南北方傳統(tǒng)民居的差異，分析形成這些差異的自然原因：——北方民居正南正北的方位觀比南方強(qiáng)；——北方民居的墻體嚴(yán)實(shí)厚重，南方民居的墻體輕薄；——從北到南，民居的屋頂坡度逐漸增大，房檐逐漸加寬，房屋進(jìn)深和高度逐漸加大。(2)下面列出的是我國南北方城市住宅摟的差異，分析導(dǎo)致這些差異的自然原因：——如果不考慮地價、建筑材料等因素，建同等面積的住房，北方的建筑成本比南方高 ；——建同樣高度的多幢樓房，北方樓房的南北間距比南方大。點(diǎn)撥：本活動要求學(xué)生了解由于地理環(huán)境的差異造成南北方建筑物特點(diǎn)的不同，并由此認(rèn)識地理環(huán)境 差異對人們生活的影響。（1）比較而言，北方的冬季寒冷而漫長，南方的夏季濕熱而漫長。為了在冬季充分利用太陽光照和熱量，北方民居正南正北的方位觀比南方強(qiáng)。北方民居的墻體嚴(yán)實(shí)厚重，利用在冬季保溫御寒；南方民居的墻體輕薄，利于在夏季通風(fēng)透氣。從北到南，年降水量逐漸增大，民居的屋頂坡度也逐漸增大（利于排水） ；隨著對保溫要求的降低和對通風(fēng)納涼要求的提高，民居的屋檐逐漸加寬，房屋進(jìn)深和高度逐漸加大。

1．閱讀圖5．16，說明產(chǎn)業(yè)向國外轉(zhuǎn)移對日本經(jīng)濟(jì)的不利影響。點(diǎn)撥：圖5．16直觀的顯示了產(chǎn)業(yè)轉(zhuǎn)移對日本經(jīng)濟(jì)的不利影響：形成“產(chǎn)業(yè)轉(zhuǎn)移出去的多，轉(zhuǎn)移進(jìn)來的少→國內(nèi)生產(chǎn)投資不足，生產(chǎn)困難→市場萎縮→產(chǎn)業(yè)向外轉(zhuǎn)移，外資不愿進(jìn)入”的惡性循環(huán)。2．盡管重化工業(yè)的環(huán)境污染比較嚴(yán)重，但是卻能為工業(yè)化的發(fā)展提供堅實(shí)的基礎(chǔ)，因此成為發(fā)達(dá)工業(yè)的象征。日本、韓國的經(jīng)濟(jì)發(fā)展都經(jīng)歷了由輕工業(yè)(勞動密集型)到重化工業(yè)(資源密集型和資金密集型)到高科技工業(yè)(技術(shù)密集型)的階段。(1）為什么日本、韓國在重點(diǎn)發(fā)展重化工業(yè)之前，要先發(fā)展勞動密集型工業(yè)?點(diǎn)撥：重化工業(yè)的發(fā)展一方面需要有一定的工業(yè)基礎(chǔ)和技術(shù)工人，另一方面需要投入大量的資金，先發(fā)展勞動密集型工業(yè)有利于利用勞動力資源豐富且廉價的優(yōu)勢，積累資金和造就產(chǎn)業(yè)工人。所以，勞動力豐富的發(fā)展中國家或地區(qū)的工業(yè)化往往從優(yōu)先發(fā)展勞動密集型工業(yè)開始。

2．通過西氣東輸輸送到上海的天然氣，價格只相當(dāng)于進(jìn)口天然氣的3／4、同等熱值煤氣的 2／3。你認(rèn)為是否應(yīng)該提高天然氣的價格，以促進(jìn)西部的發(fā)展。點(diǎn)撥：可以從不同方面分析。⑷對環(huán)境的影響①有利于改善東部地區(qū)的大氣質(zhì)量據(jù)監(jiān)測顯示，在同等熱值的情況下，與煤炭相比，利用天然氣作燃料幾乎不產(chǎn)生二氧化硫、粉塵等污染物質(zhì)，氮氧化物和二氧化碳的排放量也大為減少。長江三角洲地區(qū)的能源長期高度依賴煤炭，例如，上海市煤炭消費(fèi)量占能源消費(fèi)總量的70％。從西部地區(qū)輸送來的天然氣，可以部分替代煤炭。②為了最大限度減少對沿線地區(qū)生態(tài)環(huán)境的影響，西氣東輸工程在建設(shè)過程中，嚴(yán)格環(huán)境保護(hù)的要求。③在沿線農(nóng)村地區(qū)推廣使用天然氣，可減少農(nóng)民對薪柴的需求，從而緩解因植被破壞而帶來的環(huán)境壓力。

②其他貨幣與美元掛鉤：即各會員國貨幣對美元的匯率按各自貨幣的含金量與美元確定固定比價。各國貨幣與美元的匯率可按各國貨幣含金量與美元含金量之比來確定，這稱為法定匯率。例如，1946年一英鎊的含金量為3．58134克，一美元的含金量為0．888671克，則英鎊和美元的含金量之比1英鎊＝4．03美元就是法定匯率。這一規(guī)定，使美元等同于黃金，美元從此有了“美金”的說法；與美元比起來，其他國家的貨幣處于從屬地位，確立了美元在國際貨幣體系中的中心地位、主導(dǎo)地位正如當(dāng)時美國財政部長福勒所說：“各個行星圍繞著太陽轉(zhuǎn)，各國貨幣圍繞著美元轉(zhuǎn)?！毙〗Y(jié)： “布雷頓森林體系”是一個以美元為中心的世界貨幣體系，美國通過布雷頓森林體系，掌握了資本主義世界的經(jīng)濟(jì)命脈。（2）影響：①為世界貨幣關(guān)系提供了統(tǒng)一的標(biāo)準(zhǔn)和基礎(chǔ)，有利于維持戰(zhàn)后世界貨幣體系的正常運(yùn)轉(zhuǎn)，為世界經(jīng)濟(jì)的恢復(fù)和發(fā)展創(chuàng)造了條件。
