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."
Step 4 PracticeRead the conversation. Find out which words have been left out.Justin: Linlin, I’m going to Guizhou Province next month. I’m super excited! Any recommendations for places to visit?Linlin: Wow, cool! Guizhou is a province with a lot of cultural diversity. Places to visit...well, definitely the Huangguoshu Waterfall first.Justin: What’s special about the waterfall?Linlin: Well, have you ever heard of the Chinese novel Journey to the West ?Justin: Yes, I have. Why ?Linlin: In the back of the waterfall, you will find a cave, which is the home of the Monkey King.Justin: Really? Cool! I’ll definitely check it out.Linlin:And I strongly recommend the ethnic minority villages. You’ll find Chinese culture is much more diverse than you thought.Justin:Sounds great, thanks.Answers:Justin: Linlin, I’m going to Guizhou Province next month. I’m super excited! Do you have any recommendations for places to visit?Linlin: Wow, that’s cool! Guizhou is a province with a lot of cultural diversity. What are some places to visit in Guizhou ? Well, definitely the Huangguoshu Waterfall is the first place to visit in Guizhou Province.Justin: What’s special about the waterfall?Linlin: Well, have you ever heard of the Chinese novel Journey to the West ?Justin: Yes, I have heard of the Chinese novel Journey to the West . Why do you ask if I have heard of the Chinese novel Journey to the West?Linlin: In the back of the waterfall, you will find a cave, which is the home of the Monkey King from Journey to the West.Justin: That’s really true? It’s Cool! I’ll definitely check it out.Linlin:And I strongly recommend the ethnic minority villages on your trip to Guizhou Province.

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.
Listening and Speaking introduces the topic of “talking about how to become an astronaut”. This period is aimed to inform students some details about the requirements of being an astronaut. Students can be motivated and inspired by the astronauts. Teachers ought to encourage students to learn from them and let them aim high and dream big.Listening and Talking introduces the theme of "talk about life in space". This part also informs students more details about life in space and can inspire students to be curious about this job. 1. Guide students to listen for numbers concerning dates, years and ages etc2. Cultivate students' ability to talk about how to become an astronaut and life in space ; 3. Instruct students to use functional sentences of the dialogue such as “ first of all, I am not sure, so what might be .. I guess.. I wonder…I am curious…)appropriately.1. Guide students to understand the content of listening texts in terms of the whole and key details; 2. Cultivate students' ability to guess the meaning of words in listening; discuss with their peers how to become a qualified astronaut and describe the life in space.Part 1: Listening and SpeakingStep 1: Lead inPredictionThe teacher can ask students to predict what the listening text is about by looking at the pictures.About how to become an astronaut./the requirements of an astronautStep 2: Then, play the radio which is about an interview a. And after finishing listening for the first time, the students need to solve the following tasks.
The theme of the section is “Describe space facts and efforts to explore space”. Infinitives are one of non-finite verbs, as the subjects, objects, predicative, attributes and adverbials. This unit is about space exploration, which is a significant scientific activity, so every scientific activity has strong planning. Therefore, using the infinitives to show its purpose, explanations or restrictions is the best choice.1. Learn the structure, functions and features of infinitives.2. Learn to summarize some rules about infinitives to show purpose and modify.3. Learn to use infinitives in oral and writing English. 1. Learn the structure, functions and features of infinitives.2.

【参考范文】Narrator:(Henry is smiling as he leaves the restaurant. As he is walking down the street, he sees a sign for a place that cuts hair. He decides to get it cut. )H=Henry;B=Barber;R=rude manH:Good afternoon, I'd like to get a cut, if I may. (The barber looks at Henry's hair and continues cutting another man's hair. )Er, I'd really like a haircut. As you can see it's much too long. B:(in a rude manner) Yes, I can see that. Indeed, I can. H:Fine, well I'll have a seat then. (He sits in one of the barber's chairs. The barber turns to look at Henry. )B:It's quite expensive here, you know!Are you sure you can afford it?H:Yes. I think so. (In comes the rude man. )R:Hey you there. I need a haircut quickly. Can you do me straightaway?B:All right, then, get in the chair and I'll see what I can do. R:Thank you. (sits down in one of the barber's chairs)H:Excuse me, but I was here first. Aren't you going to do my hair first?B:This man's in a hurry. H:Well so am I!I insist that you cut my hair first. B:OK, but I'll have to be quick. This gentleman is waiting. H:Thank you. (They both become quiet. After his hair is cut, the barber tells Henry how much he must pay. Henry shows the barber the bank note. )B:Why, Mr . . . (looks shocked)H:Adams. Henry Adams. I'm sorry, I don't have any change. R:You're that Mr Adams! Well,I'm glad I waited or I might never have known it was you. B:Why, Mr Adams, please don't worry!(wearing a big smile) Nothing to worry about!Nothing at all!Please come back any time, even if you only need too little hairs cut!It will be my honour to serve you!
有的学者还指出,要坚持集体主义还必须将集体主义的价值精神与社会主义市场经济的要求结合起来,批判地继承计划经济时代倡导的集体主义,合理地对其进行体系结构的调整和内容的更新,形成新的集体主义。与传统的集体主义相比,这种新的集体主义应具有如下两个主要特点。其一,强调集体的出发点是为了维护集体成员的正当个人利益。传统的集体主义具有片面强调集体至上性、绝对性的弊端;新的集体主义必须依据社会主义市场经济的现实要求,将集体应当对个人承担的义务加以科学的阐释。真正的集体应该维护各个集体成员的个人利益,实现组成集体的各个主体的自我价值。这种新型的集体主义是对社会主义市场经济条件下社会关系的真实反映,既与个人主义有本质区别,也不同于传统的集体主义。其二,要体现道德要求的先进性与广泛性的统一。
不可知论是否认人们认识世界或彻底改造世界的可能性的哲学学说。此概念首先由英国的赫胥黎(1825—1895)于1869年提出,不可知论的思想在古代就已产生,欧洲近代的主要代表是休谟和康德。其本质是把人的感觉看作是主观和客观之间的屏障而不是桥梁,不承认在感觉之外有确实可靠的客观外部世界的存在,不懂得认识过程中本质与现象、有限与无限的辩证关系。对不可知论最有力的驳斥是实践。有时不可知论一词也用以专指针对宗教教义而提出的一种学说,认为上帝是否存在、灵魂是否不朽是不可知的。2.二元论二元论是认为世界有两个本原的哲学学说,与一元论相对立,它把物质和意识绝对对立起来,认为物质和意识是两个各自独立、相互平行发展着的实体,谁也不产生谁,谁也不决定谁,都是世界的本原。它的观点是错误的:它肯定精神不依赖于物质而独立存在,这本身就是唯心主义的观点;它虽然承认物质是独立的本原,但在说明物质和精神的关系时,又把精神说成是唯一具有能动性的力量,必然倒向唯心主义。主要代表人物是法国的笛卡儿和德国的康德。
7、人总是按照自己对周围世界和人生的理解做事。有人认为命由天定,因而身处困境只是消极等待、逆来顺受;有人认为人定胜天,因而在困难面前积极奋争、不屈不挠。以上材料说明( )A哲学源于人们对实践的追问和对世界的思考B世界观决定方法论,方法论体现着世界观C哲学不等于自发的世界观D哲学是关于世界观的学说8、世界观和方法论的关系是()A世界观和方法论相互决定B方法论决定世界观,世界观体现方法论 C世界观决定方法论,方法论体现世界观 D世界观和方法论相互影响,相互决定9、下列关于哲学、世界观、具体知识之间联系的正确说法是()A哲学是关于世界观和具体知识的统一B哲学就是科学的世界观和具体知识C哲学是关于世界观的学说,是具体知识的概括和总结D哲学决定世界观,世界观决定具体知识10、下列对哲学的认识,不正确的是()A哲学是关于世界观的学说B哲学是世界观和方法论的统一C哲学是理论化、系统化、科学化的世界观D哲学是对具体知识的概括和总结
1.根据下面的图文资料,说明前苏联垦荒区土壤风蚀的潜在自然背景。并说明人们的生产活动怎样加剧了这个过程。点拨:对图2.16的分析,要知道”垦荒地区”处于亚欧大 陆的中部偏北的地方,虽处于西风带但远离水汽来源,故降水稀少。从其周边的内陆湖“里海”、“咸海”的分布特点,可以推断,这是一个半荒漠向干草原的过渡地带,是一个生态环境比较脆弱的地区,其自然地理状况必定是寒冷、干旱、大风。2.20世纪60年代中期以来,前苏联在总结大规模垦荒经验教训的基础上,采取了一系列综合防护措施。仔细分析这些措施,你认为该地区防治荒漠化(土壤风蚀)的主要方向是什么?点拨:要善于将所列四项保护措施逐条进行分析,而后进行归纳,不难找出它们之间的共同的东西,那就是“抗旱、防风、保水、保土、保肥”。3.根据所学知识,你认为前苏联垦荒区防治荒漠化的对策与措施可以被我国的哪些地区所借鉴。
从右图“进出口贸易占全国的比重”可看出,珠三角地区的外向型经济特征很明显,但正在缓慢的发生转变;而长三角地区的外贸依存度在10年内迅速增长。由此可见,珠三角地区城市化过程,是伴随着该地特殊的经济发展相对自发地快速推进,缺乏宏观而理性的规划。阅读通过此阅读材料,使学生大致了解以下内容深圳作为珠江三角洲地区迅速城市化的一个典型代表,到目前为止,对其未来发展道路的构想,主要集中在:如何联合和依托临近区域、联合优势资源,扩大发展空间;如何明确功能,重新定位,合理分工,突出特色。活动长江三角洲地区城市的协调发展1.读图4.28,如果按人口规模>500万人、100万~500万人、50万~100万人、20万~50万人和<20万人将城市分为五级的话,分析长江三角洲地区城市的等级规模结构是否合理,这对其城市的协调发展有何影响?
1.阅读图5.16,说明产业向国外转移对日本经济的不利影响。点拨:图5.16直观的显示了产业转移对日本经济的不利影响:形成“产业转移出去的多,转移进来的少→国内生产投资不足,生产困难→市场萎缩→产业向外转移,外资不愿进入”的恶性循环。2.尽管重化工业的环境污染比较严重,但是却能为工业化的发展提供坚实的基础,因此成为发达工业的象征。日本、韩国的经济发展都经历了由轻工业(劳动密集型)到重化工业(资源密集型和资金密集型)到高科技工业(技术密集型)的阶段。(1)为什么日本、韩国在重点发展重化工业之前,要先发展劳动密集型工业?点拨:重化工业的发展一方面需要有一定的工业基础和技术工人,另一方面需要投入大量的资金,先发展劳动密集型工业有利于利用劳动力资源丰富且廉价的优势,积累资金和造就产业工人。所以,劳动力丰富的发展中国家或地区的工业化往往从优先发展劳动密集型工业开始。
2.陌生人初次见面打招呼What’s your name?(What’s = What is)Alan./I’m Alan./My name is AlanMiller.(first name,last name = family name)Are you Helen?Yes, I am.Niceto meet you.(这里的Iam 不能缩写)Nice to meetyou, too.What’s his name?His name isJim.Is she Linda?
思考:洗衣机脱水时转速高时容易甩干衣物,还是转速低时容易甩干衣物?(2) 制作棉花糖的原理内筒与洗衣机的脱水筒相似,里面加入白砂糖,加热使糖熔化成糖汁。内筒高速旋转,黏稠的糖汁就做离心运动,从内筒壁的小孔飞散出去,成为丝状到达温度较低的外筒,并迅速冷却凝固,变得纤细雪白,像一团团棉花。5.离心现象的防止在水平公路上行驶的汽车,转弯时所需的向心力是由车轮与路面的静摩擦力提供的。如果转弯时速度过大,所需向心力F大于最大静摩擦力Fmax,汽车将做离心运动而造成交通事故。因此,在公路弯道处,车辆行驶不允许超过规定的速度。当高速转动的砂轮或者飞轮内部分子间相互作用力不足以提供所需向心力时,离心运动就会使他们破裂,甚至酿成事故。
1、知识与能力:(1)识记:20 世纪 50 ~70 年代国家干预经济的政策、 70年代的经济“滞胀”“混合经济”;福利国家;第三产业的蓬勃发展;“新经济”的出现;(2)理解当代资本主义的新变化的实质是资本主义的自我扬弃,是在资本主义内部的自我改善,是资本主义生产关系的自我调整;(3)掌握以美国为代表的主要资本主义国家在战后的经济发展历程,分析各国经济发展的共同原因。2、过程与方法:(1)引导学生利用教材和相关史料,培养归纳、再现历史事件的能力,提高学生的历史思维能力;通过讨论提高学生的思辨能力,培养学生全面客观地分析问题的思维方式。(2)学生通过观察1977年发达国家国有经济比重表,懂得提取有效信息、分析数据的能力;(3)学生通过思考讨论西方福利制度的利弊,培养全面、客观分析和比较历史现象,辩证地观察和分析历史问题的能力。
(二)进行新课1、动能与势能的相互转化演示实验1:如右图,用细线、小球、带有标尺的铁架台等做实验。把一个小球用细线悬挂起来,把小球拉到一定高度的A点,然后放开,小球在摆动过程中,重力势能和动能相互转化。我们看到,小球可以摆到跟A点等高的C点,如图甲。如果用尺子在某一点挡住细线,小球虽然不能摆到C点,但摆到另一侧时,也能达到跟A点相同的高度,如图乙。问题:这个小实验中,小球的受力情况如何?各个力的做功情况如何?这个小实验说明了什么?学生观察演示实验,思考问题,选出代表发表见解。小球在摆动过程中受重力和绳的拉力作用。拉力和速度方向总垂直,对小球不做功;只有重力对小球能做功。实验证明,小球在摆动过程中重力势能和动能在不断转化。在摆动过程中,小球总能回到原来的高度。可见,重力势能和动能的总和保持不变。即机械能保持不变。
【学习内容分析】在行星运动规律与万有引力定律两节内容之间安排本节内容,是为了更突出发现万有引力定律的这个科学过程。如果说上一节内容是从运动学角度描述行星运动的话,那么,本节内容是从动力学角度来研究行星运动的,研究过程是依据已有规律进行的演绎推理过程。教科书在尊重历史事实的前提下,通过一些逻辑思维的铺垫,让学生以自己现有的知识基础身于历史的背景下,经历一次“发现”万有引力的过程,因此体验物理学研究问题的方法就成为主要的教学目标。【学情分析】在学太阳对行星的引力之前,学生已经对力、重力、向心力、加速度、重力加速度、向心加速度等概念有了较好的理解,并且掌握自由落体运动和圆周运动等运动规律,能熟练运用牛顿运动定律解决动力学问题。已经完全具备深入探究和学习万有引力定律的起点能力。所以在推导太阳与行星运动规律时,教师可以要求学生自主地运用原有的知识进行推导,并要求说明每一步推理的理论依据是什么,教师仅在难点问题上做适当的点拨。
世界能源问题的解决途径是什么?能源,是人类敕以生存和进行生产的不可缺少的资源.近年来,随着生产力的发展和能源消费的增长.能源问题已被列为世界上研究的重大问题之一.解决世界能源问题的根本途径,主要有两个方面:其一是广泛开源,其二是认真节流.所谓开源,就是积极开发和利用各种能源.在继续加紧石油勘探和寻找新的石油产地的同时,积极开发丰富的煤炭资源,还要大力开发水能,生物能等常规能源,加强核能、太阳能,风能、沼气,海洋能,地热能以及其他各种新能源的研究和利用,从而不断扩大人类的能源资源的种类和来源.所谓节流,就是要大力提倡节约能源.节能是世界上许多国家关心和研究的重要课题,甚至有人把节能称为世界的“第五大能源”,与煤、石油和天然气、水能、核能等并列.在节能方面,在有计划地控制人口增长的同时,重点要发挥先进科学技术的优势,提高各国的能源利用效率.
