Step 3 Analyzing article structureActivity 31. Teachers raise questions to guide students to analyze the chapter structure of this diary and think about how to describe the festival experience. (1)What should be included in the opening/body/closing paragraph(s)?(2)How did the writer arrange his/her ideas?(3)What kind of interesting details did the writer describe?(4)How did the writer describe his/her feelings/emotions during the event?2. Students read and compare the three sentence patterns in activity 2. Try to rewrite the first paragraph of the diary with these three sentence patterns. After that, students exchange corrections with their partners. Such as:●This was my first time spending three days experiencing the Naadam Festival in China’s Inner Mongolia Autonomous Region and it was an enjoyable and exciting experience. ●I'll never forget my experience at the Naadam Festival because it was my first time to watch the exciting Mongolian games of horse racing, wrestling, and archery so closely. ●I'll always remember my first experience at the Naadam Festival in China’s Inner Mongolia Autonomous Region because it was so amazing to spend three days witnessing a grand Mongolian ceremony. Step 4 Accumulation of statementsActivity 41. Ask the students to read the diary again. Look for sentences that express feelings and emotions, especially those with the -ing form and the past participle. Such as:● …h(huán)orse racing, wrestling, and archery, which are all so exciting to watch. ● some amazing performances● I was surprised to see…● I was a little worried about. . . ● feeling really tiredOther emotional statements:●I absolutely enjoyed the archery, too, but the horse races were my favourite part. ●I'm finally back home now, feeling really tired, but celebrating Naadam with my friend was totally worth it. ●He invited me back for the winter to stay in a traditional Mongolian tent and cat hot pot. I can’t wait!2. In addition to the use of the -ing form and the past participle, the teacher should guide the students in the appreciation of these statements, ask them to memorize them, and encourage them to use them reasonably in writing practice.

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.

思考提示在階級社會(huì)中，社會(huì)基本矛盾的解決主要是通過階級斗爭實(shí)現(xiàn)的，階級斗爭是推動(dòng)階級社會(huì)發(fā)展的直接動(dòng)力，當(dāng)舊的生產(chǎn)關(guān)系嚴(yán)重阻礙生產(chǎn)力發(fā)展，需要進(jìn)行變革時(shí)，代表舊的生產(chǎn)關(guān)系的沒落階級卻不會(huì)自動(dòng)退出歷史舞臺(tái)，利用舊的上層建筑維護(hù)自己的統(tǒng)治，只有代表新生產(chǎn)力發(fā)展方向的階級通過社會(huì)革命，推翻沒落的階級統(tǒng)治，才能解放生產(chǎn)力，推動(dòng)社會(huì)向前發(fā)展。所以，階級社會(huì)的進(jìn)步往往是通過激烈的社會(huì)革命實(shí)現(xiàn)的。但是，社會(huì)主義社會(huì)與階級社會(huì)不同，這是因?yàn)椋鐣?huì)主義社會(huì)中，生產(chǎn)力和生產(chǎn)關(guān)系、經(jīng)濟(jì)基礎(chǔ)和上層建筑之間的矛盾是一種非對抗性矛盾，不需要通過一個(gè)階級推翻另一個(gè)階級的階級斗爭的方式來解決，只能通過改革實(shí)現(xiàn)社會(huì)的發(fā)展，通過對生產(chǎn)關(guān)系和上層建筑進(jìn)行改革，實(shí)現(xiàn)社會(huì)主義的自我完善，從而促進(jìn)社會(huì)的發(fā)展。所以，我國經(jīng)濟(jì)體制改革是在堅(jiān)持社會(huì)主義制度的前提下，改革生產(chǎn)關(guān)系和上層建筑中不適應(yīng)生產(chǎn)力發(fā)展的一系列相互聯(lián)系的環(huán)節(jié)和方面。

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；深層地下水是長時(shí)間內(nèi)滲入地下深入儲(chǔ)存起來的，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，對流域自然條件復(fù)雜的大的河流來說尤其如此。我國長江上游地區(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。

1．根據(jù)下面的材料，歸納珠江三角洲發(fā)展基塘生產(chǎn)有利的地理?xiàng)l件。珠江三角洲地勢低平，河網(wǎng)密布，降水充沛。北回歸線從珠江三角洲的北部穿過。桑樹和甘蔗主要分布于熱帶和亞熱帶。廣州是古代海上絲綢之路的起始地之一。水產(chǎn)品在廣東人的食物結(jié)構(gòu)中占有較大的比重。點(diǎn)撥珠江三角洲地區(qū)發(fā)展基塘農(nóng)業(yè)生產(chǎn)有利條件可以結(jié)合材料，歸納為三個(gè)方面：地形、氣候、市場（當(dāng)?shù)睾秃Ｍ猓┚唧w分析略。2．圖4．16所示的基塘生產(chǎn)將哪些產(chǎn)業(yè)聯(lián)系起來?哪些副產(chǎn)品(或廢棄物)被充分利用起來?這種聯(lián)系對農(nóng)村經(jīng)濟(jì)發(fā)展有什么作用?點(diǎn)撥基塘生產(chǎn)環(huán)節(jié)將種植業(yè)（桑、蔗等）、養(yǎng)殖業(yè)（養(yǎng)蠶、養(yǎng)魚）、工業(yè)（絲廠、糖廠）等幾種產(chǎn)業(yè)緊密的聯(lián)系在一起。在此環(huán)節(jié)中，塘泥、蠶沙（蠶屎）、蠶蛹、繅絲、濾泥、蔗葉等副產(chǎn)品被充分的回收利用。養(yǎng)蠶業(yè)、蔗糖加工業(yè)同塘魚養(yǎng)殖業(yè)緊密結(jié)合，作為一種綜合的經(jīng)營，幾者之間相互依存、相互促進(jìn)、揚(yáng)長補(bǔ)短，有機(jī)地循環(huán)聯(lián)系起來。

2．通過西氣東輸輸送到上海的天然氣，價(jià)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(jià)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。
