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."

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.

⑦在我看来, 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.

一 减数分裂高一生物减数分裂说课稿各位评委、老师:大家好,我今天说课的题目是高中生物必修2第二章第一节〈〈减数分裂与受精作用〉〉第一部分减数分裂第一课时精子形成过程。接下来我就从以下几个方面来说说这一节课。一、说教材1.教材地位和作用《减数分裂》这一部分内容不仅是第二章的重点内容,也是整本书的重点内容之一。它以必修一学过的细胞学知识、染色体知识、有丝分裂知识和初中生殖种类知识为基础。通过学习,使学生全面认识细胞分裂的种类、实质和意义,为后面学习遗传和变异,生物的进化奠定细胞学基础。2.教学目标(1)知识目标:掌握减数分裂的概念和精子的形成过程;理解减数分裂和受精作用的意义。(2)能力目标:通过观察减数分裂过程中染色体的行为变化,培养学生识图、绘图能力以及比较分析和归纳总结的能力。
课前活动:分成四组,对南京三个住房地段进行调查,新街口夫子庙、板仓、仙林,对住房居民进行问卷调查,自行设计调查问卷,分析该地段的房价要求,居民的要求,居民为何要在该地段购买住房,基础设施设置等等其它与居民购房有关的因素。◆设计意图:利用课前小组探究形式对所学问题进行相关调查,不仅让学生掌握知识了解知识来源于社会还能培养学生深入生活交际表达能力以及合作探究能力;3.问题设计同学们,不知道你们在调查过程中是否发现一个问题,郊区的房子,特别是别墅,都是些高档居所,许多有钱人的居住场所,那为什么会这样呢?伴随着城市化进程中居民都往城里挤,为什么还会有许多有钱人往郊区搬呢?这就是我们今天要研究的第二个问题:逆城市化。◆设计意图:承转过渡知识,从购房选择因素的学习过渡到郊区化的学习,同时培养学生发现问题的能力,给学生以启迪。
d.某物体沿直线向东运动,原来的速度是5m/s,2s后速度减小到3m/s,求2s内物体速度变化。④如何探究物体作匀速圆周运动时,在Δt时间内的速度变化?分析:有了同一直线上速度变化的铺垫后,讨论物体做匀速圆周运动速度的变化就比较自然了,为了给向心加速度方向的学习打好基础,可以通过小组协作,进一步完成下列思考题,使同学们认识到:时间间隔起短,速度变化的方向起接近半径方向。(多媒体屏幕投影)a.物体沿半径为1m的轨道做匀速圆周运动,线速度大小为,求1s内物体速度变化并画出1s内速度变化的示意图。b.分别求出上题中物体在0.5s、0.25s内速度变化并画出相应的示意图。由于没有办法直接利用实验来验证速度变化的方向,所以,我们采用提供思考题的方法,引导同学在合作学习、自主探究中完成。有了速度变化的研究为铺垫,加速度的方向问题就迎刃而解了。
(3)内陆和中西部城镇主要以煤和火电为主;广大农村和边远地区大多正从使用农作物秸秆等生物能源。(4)人均能源资源不足。我国是世界第三大能源生产国和第二大能源消费国,而我国能源短缺,特别是油气资源短缺已成为制约我国经济发展的重要因素。相关数据——煤炭、石油和天然气的人均资源占有量只有95t,世界平均值为209t,约是世界人均值的1/2;我国人均石油可采储量3t,世界平均值为28t,约为世界平均值的1/10。我国人均能源消费量不足1.2吨标准煤,居世界89位,不足世界人均能源消费水平的一半,仅占发达国家的1/5~1/10。其中人均消费650kg标准煤,是世界平均额的95%;人均消费石油相当145kg标准煤,为世界平均数的16.8%;人均消费天然气相当17.7kg标准煤,为世界平均数的3.9%;人均消费电力501.5kWh,为世界平均水平的25%。(5)是能源消费结构不合理,突出存在着一低两高:即电能消费比例低,非商品生物能源消费量高,一次性商品能源消费中原煤消费比重高。原煤消费达到75%,远高于26.2%的世界平均水平。
2、教学目标根据我对教材的理解、结合学生的实际情况、渗透新课程的教学理念,为提高全体学生的科学素养,按课程标准,以促进全体学生发展为目的。从知识与技能、过程与方法,情感态度与价值观三个方向培养学生,拟定三个教学目标:知识与技能:(1)知道什么是动能。(2)正确理解和运用动能公式分析、解答有关问题。(3)掌握外力对物体所做的总功的计算,理解“代数和”的含义。(4)理解和运用动能定理。过程与方法:通过演绎推理过程,培养科学研究兴趣,领略物理学中所蕴含的严谨的逻辑关系。情感、态度、价值观:通过运用动能定理分析解决问题,感受成功的喜悦,培养学生对科学研究的兴趣。3、教学的重点和难点重点:理解动能定理、应用动能定理解决力学问题。难点:应用动能定理解决多个过程的力学问题,以及变力做功或曲线运动中的动能定理运用。
设计意图:通过设疑、讨论及学生的亲身体验与教师的引导,得到描述圆周运动快慢的两个物理量,也就成功的打破了学生在认识上的思维障碍,突破了物理概念教学的难点。在解决线速度和角速度的问题之后,我将引领学生学习匀速圆周运动的概念以及匀速圆周运动中线速度、角速度的特点。并引出匀速圆周运动中周期、转速的知识。为了加深学生对线速度、角速度与半径关系的认识,我设计了第三个学生体验活动:四名学生以我为圆心做圆周运动,四名学生始终并列,这时里圈同学走动不急不慢,而外圈同学则要小跑。通过学生的活动,不难发现在角速度相同的情况下,半径越大的线速度也越大。定性的得到了线速度、角速度与半径的关系。接下来让学生利用所学知识推导线速度、角速度与半径的关系。设计意图:这样就通过设疑、学生猜想、体验、推导的方式得到了结论,突破了本节课的难点即线速度、角速度与半径的关系。
进一步引导学生思考利用数学知识可写成等式F=kma学生很自然就会思考比列系数K应该是多少?通过教师引导学生举例各国长度单位不同(如英国:英里、码、英尺、英寸;中国:市里、市丈、市尺、市寸、市分 )导致交流不便。为了适应各国交流需要国际计量局规定了一套统一的单位,称为国际单位制 。取不同的单位制K是不同的,为了简洁方便,在选取了质量和加速度的国际单位(Kg, m/s2)时规定K=1。那么就有;F=ma为了纪念牛顿,就把能使1kg物体获得1m/s2加速度的力称做一牛顿,用符号N表示问题:实际物体受力往往不止一个,多个力情况应该怎么办呢?平行四边形法则进一步引导学生得出牛顿第二定律更一般的表达式: F合=ma思考.讨论我们用力提一个很重的箱子,却提不动它。这个力产生了加速度吗?要是产生了,箱子的运动状态却并没有改变。为什么?
问:为什么会出现这样的情况,男女生之间的拉力存在着怎样的大小关系?进一步求证这两个力的大小关系经过共同讨论,得方案:把两个弹簧秤勾在一起,重现拔河比赛,分三种情况进行。(通过摄像头把弹簧秤的读数放大)两弹簧称勾在一起拉,处于静止不动时(即拔河比赛,双方处于僵持状态)两弹簧称勾在一起拉,并向一方运动(即比赛绳子被拉向一方时的状态)3、两弹簧称勾在一起拉,一方方向慢慢改变(两力方向始终在一条直线上)实验结论:两弹簧称的读数的变化总是相同的,大小相等,方向相反。得到牛顿第三定律:追问:既然两个力大小相等,那么拔河比赛为什么还存在胜负之分?讲清作用力与反作用力作用的受力物体不同,并和学生讨论如何做才会获胜。回应课前问题:“以卵击石”为什么鸡蛋碎?
1、汉武帝尊儒的措施:(1)政治方面:起用很多儒学家参与国家大政。他规定,地方定期选出孝子、廉吏当中央任官,甚至还擢升平民、儒士为相。这明显扩大了官员的队伍,提高了官员的文化素质,巩固了封建统治基础,成为汉武帝文治武功的重要组成部分。也给后世封建王朝在用人方式方法上面提供了宝贵的借鉴和启迪。(2)思想方面:采纳董仲舒的建议,“罢黜百家 独尊儒术”(3)教育方面:儒家经典“五经”为国家规定的教科书。兴办太学和设立地方学校进行儒学教育。公元前136年,汉武帝正式规定《诗》、《书》、《礼》、《易》、《春秋》为“五经”;前124年,又在长安兴办太学,规定太学生员为博士弟子,一律由儒家五经博士负责教授,学完经考试合格后即可到政府任官。这是封建国家利用政权的力量兴办教育、提倡儒学,其必然对整个社会的教育事业有一定的导向作用。
