1. In Picture 1 and Picture 2, where do you think they are from? How do you know?From their wearings, we can know they are from ethnic minority of China--- Miao and Dong.Picture 1, they are playing their traditional instrument lusheng in their traditional costumes.Picture 2. the girls are Miao because they wear their traditional costumes and silver accessory.2. In Picture 3, can you find which village it is? What time is it in the picture?It is Dong village. It is at night. Step 2 While-listeningJustin met a new friend while traveling in Guizhou. Listen to their conversation and complete the summaries below.Part 1Justin and Wu Yue watched some Miao people play the lusheng. The instrument has a history of over 3,000 years and it is even mentioned in the oldest collection of Chinese poetry. Then they watched the lusheng dance. Justin wanted to buy some hand-made silver/traditional accessories as souvenirs. He was told that the price will depend on the percentage of silver. Part 2They will go to a pretty Dong minority village called Zhaoxing. they will see the drum towers and the wind and rain bridges. They may also see a performance of the Grand Song of the Dong people.Step 3 Post-listening---TalkingWork in groups. Imagine Justin is telling some friends about his trip to Guizhou. One of you is Justin and the rest of you are his friends. Ask Justin questions about his trip and experience. The following expressions may help you.
另一方面,其余的人反对这个计划,因为它可能会导致一些不好的影响。7.I hold the belief that space exploration not only enable us to understand how the universe began but also help us survived well into the future.我坚信探索太空不仅能够使我们了解宇宙的起源而且能够帮助我们更好地走进未来。8.I think we should spend more time and money exploring space so as to provide new and better solutions to people's shortterm and longterm problems.为了给人类的短期和长期问题提供更新和更好的解决方法,我认为我们应该花更多的时间和金钱来探索太空。9.From my point of view,it is wrong of young people to depend on their telephones too much,which may do harm to both their physical and mental health.在我看来,年轻人过度依赖手机是不对的,因为它们可能会对他们的身心健康都有害。最近你班同学就“人类是否应该进行宇宙探索”这个问题进行了激烈的讨论。有人认为,探索宇宙不仅让人类更好地了解宇宙的发展,还可以用来指导农业生产,以及把一些探索太空的高新技术用于现实生活;也有一些人认为探索太空花掉了大量的人力物力;影响了人们的生活水平。请你根据以下情况写一篇报告并发表自己的观点。注意:1.写作内容应包括以上全部要点,可适当发挥,使上下文连贯;
Step 4: Listen again and decide if the following statements are true (T) or false (F).1 It was the first time Chen Liyan's story was reported. T口 F口2 Chen found 10,000 yuan in a small plastic bag in Taiyuan railway station口 F口3 Wang Zheng apologized to Chen because he couldn't offer her more money. T口 F口4 Chen took out a large loan to cure her daughter, T口 F口5 Wang set up a fundraising website for Chen's daughter after Chen told him about her situation. T口 F口Step 5:After listening, discuss the questions.1 What kind of person do you think Chen Liyan is?Chen Liyan is generous and honest because she returned a large sum of money to the owner.2 Did Chen return the money because she didn't need it?No. She returned the money because it was the right thing to do. Evidence for this is that she refused to accept the reward money because she felt that it had not been earned. 3 Is it common for people to do what Chen did?It depends on the culture. In some countries it is quite common to return money that has been found. In other countries, people believe "Finders are keepers!" 4 How did Wang Zheng feel about the return of his money?He must have been very happy and relieved to have gotten his money back. We know this because he thanked Chen repeatedly and even offered her a reward.5 Why did Ma Dongbao tell Wang about Chen's family?He must have had great sympathy for Chen and her daughter and wanted to help them.'We know this because he arranged help for them. 6 How did the news reporter feel about Chen's actions?The news reporter felt that it showed that money wasn't the most important thing in life. We know this because the reporter told us that this is what Chen believes. and then said, “that's a great attitude to take."

This happens because the dish soap molecules have a strong negative charge, and the milk molecules have a strong positive charge. Like magnets, these molecules are attracted to each other, and so they appear to move around on the plate, taking the food coloring with them, making it look like the colors are quickly moving to escape from the soap.Listening text:? Judy: Oh, I'm so sorry that you were ill and couldn't come with us on our field trip. How are you feeling now? Better?? Bill: Much better, thanks. But how was it?? Judy: Wonderful! I especially liked an area of the museum called Light Games.it was really cool. They had a hall of mirrors where I could see myself reflected thousands of times!? Bill: A hall of mirrors can be a lot of fun. What else did they have?? Judy: Well, they had an experiment where we looked at a blue screen for a while, and then suddenly we could see tiny bright lights moving around on it. You'll never guess what those bright lights were!? Bill: Come on, tell me!? Judy: They were our own blood cells. For some reason, our eyes play tricks on us when we look at a blue screen, and we can see our own blood cells moving around like little lights! But there was another thing I liked better. I stood in front of a white light, and it cast different shadows of me in every color of the rainbow!? Bill: Oh, I wish I had been there. Tell me more!? Judy: Well, they had another area for sound. They had a giant piano keyboard that you could use your feet to play. But then, instead of playing the sounds of a piano, it played the voices of classical singers! Then they had a giant dish, and when you spoke into it, it reflected the sound back and made it louder. You could use it to speak in a whisper to someone 17 meters away.? Bill: It all sounds so cool. I wish I could have gone with you? Judy: I know, but we can go together this weekend. I'd love to go there again!? Bill: That sounds like a great idea!

1.流水堆积地貌由于河床坡度降低,导致流速减小 ,或者其他原因,引起河流搬运能力降低,促使沉积发生,形成堆积地貌。常见的河流堆积地貌主要有以下几种:(1)冲积扇平原冲积扇是河流出山口处的扇形堆积体。河流出 山口后,比降显著减小,水流又分成许多交汉,成扇状向外流动,河流能量显著降低,大量物质堆积下来,又有利于河流改道。随着各支汊的不断堆积和变迁,就形成冲积扇。冲积扇的物质结构,一般是顶部物质较粗,主要为沙、砾 ,随着水流搬运能力向边缘减弱,堆积的物质逐渐变细,边缘一般多为沙、粉沙及亚粘土,分选性较好,所以冲积扇是较好的含水层,边缘常有泉水出 露,可发展自流灌 溉。若山地河谷随山地间歇抬升,也可形成叠置冲积扇。(2)河漫滩平原河漫滩平原发源于河流中下游。在河流中下游地区,河流下蚀作用减弱,侧蚀作用加强,河流往往凹岸侵蚀,在凸岸堆积形成水下堆积体。堆积体 的面积逐渐扩大,在枯水季节露出水面,形成河漫滩(见下图)。

尽管如此,农民工作为一个新的社会阶层,其独特的经济需求和政治诉求应该得到充分的尊重。虽然农民工的“根”还在农村,但是他们已经脱胎换骨,日益成长为一个迫切需要社会认可的新兴阶层。3.农民工处于何种生存境况?作为“廉价劳动力”,工资水平低,拖欠时有发生。作为“超时劳动力”,工作时间极长,超负荷从事繁重工作。作为“高危劳动力”,社会保障缺失,各种安全事故频繁。4.农民工问题有多么重要?农民工问题关系到农业增效、农民增收和农村繁荣。农民工问题关系到工业化、城镇化和“以工补农、以城促乡”。农民工问题关系到社会主义和谐社会建设。5.解决农民工问题应该做些什么?构建城乡一体化就业体系。健全农民工权益保障制度。强化农民工输出地和输入地培训。稳妥解决农民工户籍问题。改进对农民工的管理和服务。
案例探究:环地中海地区农业的变迁让学生思考:此地哪些因素发生了变化,农业生产方式进行了如何调整?效果如何?二、农业地域的形成1、农业地域的概念:由于以上各因素的共同影响,在一定的地域和一定的历史条件下,形成了相应的生产地区,称为农业地域。农业地域的类型主要有:种植业、畜牧业、混合农业。(在这里分别给学生展示一些农业生产类型的图片,并简单说明什么是种植业、什么是畜牧业、及什么是混合农业)案例探究:阅读澳大利亚地混合农业生产思考:(1)、澳大利亚农业生产的特点是什么?(2)、澳大利亚混合农业的分布在哪里?受哪些区位因素的影响?(3)澳大利亚混合农业生产有哪些优点?
思考:结合资料,看看“广钢”的搬迁还考虑到什么因素?主要从谁的角度去考虑?展示资料:广钢建于1958年,由于城市化进程的加快,原来地处偏僻的广钢一带现已成闹市,广钢因此给周边带来了许多不便,并屡被投诉,投诉的主要内容是烟气、粉尘超标。近日,《珠三角环境保护规划纲要(草案)》(以下简称《纲要》)正式提交省人大常委会审议,按照《纲要》要求,2010年前,广东省将关、停、并、转、迁位于城市中心区高能耗、重污染的工业企业。学生讨论:环保要素、政策要素……从市民、政府等社会角度去考虑板书:2、环保要素 3、政策的变化小结:影响工业区位选择的因素很多,不同的工业区位选择要考虑的主导因素可能是一个或几个,应因地制宜,具体分析。并且影响区位选择的因素随着社会的发展而变化;社会、环境需要对工业区位也有一定的影响力。所以工业区位选择是复杂的,应综合考虑各种因素,以取得最大的经济、社会、环境综合效益。学生活动:计算机模拟工业选址,看谁是最英明的决策者(通过实践应用让学生感受到工业的区位选择应综合考虑)
③在萨斯索罗地区集聚的相关企业和服务性机构有哪些?④萨斯索罗瓷砖工业小区的生产—销售—服务网络中支撑企业、辅助性企业、服务性企业、服务性机构有哪些?学生回答问题后教师小结:意大利的新工业区,以中小企业集聚的工业小区为独特的发展模式。工业小区的优势是有助于加强专业化,提高生产效率,降低生产成本,增强在市场上的竞争力。完成课本70页活动:1. 比较温州乡镇企业与意大利新工业区的发展有什么异同(相同:有大批廉价劳动力,企业规模小,以轻工业为主,企业生产高度专业化,资本集中程度低。不同:最大的不同是意大利工业小区密切联系协作,共同形成巨型企业,温州虽生产同种产品,但是联系协作不如意,形成多家企业竞争局面,规模效应大减。)2. 温州乡镇企业的发展有哪些些问题?你能为其解决这些问题提出合理化的建议吗?(加大技术投入,企业间联系协作,杜绝恶性竞争等)

3、东北区商品粮基地的建设松嫩平原和三江平原是我国最重要的商品粮基地,三江平原所能够提供的商品粮比重在全国最大,而且开发历史短、地广人稀、土地资源丰富、具有较大的开发潜力。4、东北区商品粮基地的综合开发东北区农业基地的综合开发,就是要在不断提高种植业本身生产潜力的基础上,大力发展养殖业和农产品加工业,使农产品多层次大幅度升值。总结:搞好商品粮基地和林业基地建设,必须从改善农业生态环境出发,坚持开发和利用、治理和保护相结合,坚持经济效益、生态效益相统一。这就要求不能通过大幅度开垦荒地、增加耕地面积来发展粮食生产,发挥现有耕地的生产潜力,提高单产是今后实现粮食增产的根本途径。【知能训练】一、选择题(第1-4题为单项选择题,第5-6题为双项选择题)1、保护和提高黑土肥力最有效的办法是 ( )A、秸秆还田B、增施化肥C、植树造林D、焚烧秸秆
