⑦在我看來(lái), 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.

淺層地下水是貯存于地表松散堆積物中的潛水。主要受降水、氣溫、蒸發(fā)等氣象因素影響，有明顯的季節(jié)變化與日變化，并與河水有相應(yīng)補(bǔ)給關(guān)系，即河水高于潛水面時(shí)，河水補(bǔ)給地下水，反之地下水補(bǔ)給河流；深層地下水是長(zhǎng)時(shí)間內(nèi)滲入地下深入儲(chǔ)存起來(lái)的，它緩慢地流出補(bǔ)給河流，受氣象因素影響很小，通常只有年變化，季節(jié)變化已不明顯。當(dāng)然，一條河流的河水補(bǔ)給來(lái)源往往不是單一的，而是以某一種形式為主的混合補(bǔ)給形式，對(duì)流域自然條件復(fù)雜的大的河流來(lái)說(shuō)尤其如此。我國(guó)長(zhǎng)江上游地區(qū)除雨水、地下水外，高原高山上冰川、積雪在夏季融化也補(bǔ)給河流；東北地區(qū)的河流，由春季融化積雪補(bǔ)給，夏季則由雨水和地下水補(bǔ)給；西北內(nèi)陸盆地除雨水外，夏季高山冰川、積雪融化成為河流的主要補(bǔ)給形式。我國(guó)季風(fēng)地區(qū)，大部分河流以雨水補(bǔ)給為主，而冬季則由地下水補(bǔ)給。

人教版高中地理必修1第四章第三節(jié)河流地貌的發(fā)育教案
1．流水堆積地貌由于河床坡度降低，導(dǎo)致流速減小 ，或者其他原因，引起河流搬運(yùn)能力降低，促使沉積發(fā)生，形成堆積地貌。常見(jiàn)的河流堆積地貌主要有以下幾種：(1)沖積扇平原沖積扇是河流出山口處的扇形堆積體。河流出 山口后，比降顯著減小，水流又分成許多交漢，成扇狀向外流動(dòng)，河流能量顯著降低，大量物質(zhì)堆積下來(lái)，又有利于河流改道。隨著各支汊的不斷堆積和變遷，就形成沖積扇。沖積扇的物質(zhì)結(jié)構(gòu)，一般是頂部物質(zhì)較粗，主要為沙、礫 ，隨著水流搬運(yùn)能力向邊緣減弱，堆積的物質(zhì)逐漸變細(xì)，邊緣一般多為沙、粉沙及亞粘土，分選性較好，所以沖積扇是較好的含水層，邊緣常有泉水出 露，可發(fā)展自流灌 溉。若山地河谷隨山地間歇抬升，也可形成疊置沖積扇。(2)河漫灘平原河漫灘平原發(fā)源于河流中下游。在河流中下游地區(qū)，河流下蝕作用減弱，側(cè)蝕作用加強(qiáng)，河流往往凹岸侵蝕，在凸岸堆積形成水下堆積體。堆積體 的面積逐漸擴(kuò)大，在枯水季節(jié)露出水面，形成河漫灘(見(jiàn)下圖)。

人教版高中地理必修1冷熱不均引起的大氣運(yùn)動(dòng)教案
討論：二氧化碳在大氣的受熱過(guò)程中起到了什么作用？（吸收太陽(yáng)輻射中的紅外線輻射和地面輻射，保溫作用）大氣中的二氧化碳濃度增大對(duì)氣溫有什么影響？（全球氣候變暖）閱讀：我們知道了太陽(yáng)輻射中的可見(jiàn)光和紅外 光能量的吸收和轉(zhuǎn)化，那么紫外區(qū)的能量到哪兒去了？請(qǐng)同學(xué)們查閱資料，自主探討。小結(jié)：大氣的受熱過(guò) 程就是太陽(yáng)曬熱了地面，地面烘熱了大氣。太陽(yáng)輻射是大氣的根本熱源，地面輻射是大氣的直接熱源。這就是為什么海拔越高，氣溫越低的原因，難怪高處不勝寒！轉(zhuǎn)承：大氣的直接熱源是地面，不同性質(zhì)的地面溫度是不同的，同緯度，海洋和陸地就有溫差。提問(wèn)：請(qǐng)學(xué)生說(shuō)說(shuō)白天和晚上在海邊的不同感受。由白天和晚上的風(fēng)向不同切入實(shí)驗(yàn)P32活動(dòng)。討論：通過(guò)煙霧的飄動(dòng)，我們得出了什么規(guī)律？冷熱不均引起了熱力環(huán)流板書(shū)： 二、熱力環(huán)流板圖與分析：結(jié)合試驗(yàn)，學(xué)生分析熱力環(huán)流 的產(chǎn)生
