The topic of this part is “Describe a place with distinctive cultural identity”.This section focuses on Chinese culture by introducing Chinatown, whose purpose is to show the relationship between the Chinese culture and American culture. The Chinese culture in Chinatown is an important part of American culture. Chinatown is an important window of spreading Chinese culture and the spirit homeland of oversea Chinese, where foreigners can experience Chinese culture by themselves.Concretely, the title is “Welcome to Chinatown!”, from which we can know that the article aims at introducing Chinatown. The author used the “Introduction--Body Paragraph--Conclusion” to describe the people, language, architecture, business, famous food and drinks and people’s activities, which can be a centre for Chinese culture and shows its unique charm.1. Read quickly to get main idea; read carefully to get the detailed information.2. Learn the characteristics of writing and language.3. Learn to introduce your own town according to the text.4. Learn to correct others’ writing.1. Learn the characteristics of writing and language.2. Learn to introduce your own town according to the text.Step 1 Lead in ---Small talkIn the reading part, we mentioned the Chinatown of San Francisco. How much do you know about Chinatown of San Francisco ?Chinatown is a main living place for Chinese immigrants, where you can see many Chinese-style buildings, costumes, operas, restaurants, music and even hear Chinese.Step 2 Before reading ---Predict the contentWhat is the writer’s purpose of writing this text ? How do you know ?From the title(Welcome to Chinatown) and some key words from the text(tourist, visit, visitors, experience), we can know the purpose of the text is to introduce Chinatown and show the relationship between Chinese culture and American culture.

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.

Discuss these questions in groups.Q1: Have you ever been to a place that has a diverse culture ? What do you think about the culture diversity ?One culturally diverse place that I have been to is Harbin, the capital city of Heilongjiang Province. I went there last year with my family to see the Ice and Snow Festival, and I was amazed at how the culture as different to most other Chinese cities. There is a big Russian influence there, with beautiful Russian architecture and lots of interesting restaurants. I learnt that Harbin is called “the Oriental Moscow” and that many Russians settled there to help build the railway over 100 years ago.Q2: What are the benefits and challenges of cultural diversity ?The benefits: People are able to experience a wide variety of cultures, making their lives more interesting, and it can deepen the feelings for our national culture, it is also helpful for us to learn about other outstanding culture, which helps improve the ability to respect others. The challenges: People may have trouble communicating or understanding each other, and it may lead to disappearance of some civilizations and even make some people think “The western moon is rounder than his own.”Step 7 Post reading---RetellComplete the passage according to the text.Today, I arrived back in San Francisco, and it feels good (1) _____(be) back in the city again.

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.

The themes of this part are “Talk about how to become an astronaut” and “Talk about life in space”. As Neil Armstrong said “Mystery creates wonder and wonder is the basis of man’s desire to understand. Space is difficult for human to reach, therefore, humans are full of wonders about it. However, if wanting to achieve the dream of reaching the Moon, some of our human should work hard to be an astronaut at first. Part A(Talk about how to become an astronaut) is a radio interview in a radio studio, where the host asked the Chinese astronauts about his story how to become an astronaut. Yang Liwei told his dreamed to be an astronaut since childhood. Then he worked hard to get into college at 22. The next 10 years, he gradually became an experienced pilot. At the same time, to be an astronaut, he had to study hard English, science and astronomy and trained hard to keep in good physical and mental health and to practise using space equipment. Part B (Talk about life in space) is also an interview with the astronaut Brown, who is back on the earth. The host Max asked about his space life, such as his emotion about going back the earth, the eating, shower, brushing, hobbies and his work. Part A and Part B are interviews. So expressing curiosity about the guests’ past life is a communicative skill, which students should be guided to learn.1. Students can get detailed information about how Yang Liwei became an astronaut and Max’s space life.2. Students learn to proper listening strategy to get detailed information---listening for numbers and taking notes.3. Students can learn related sentences or phrases to express their curiosity like “ I wish to know...” “I’d love to know...”4. Students can learn more about the space and astronauts, even be interested in working hard to be an astronaut

The theme of this unit focuses on “space exploration.” Students will learn about the training and experience needed to become an astronaut. The text is mainly about the development of space exploration. On the one hand, the text helps students to have a good understanding about the great feats humans have achieved, on the other hand, they will further understand the contributions that we Chinese have achieved, and feel confident and proud about our homeland and strengthen their love for our country. The teacher should instruct students to aim high and study harder to make great progress in the space career if possible.1. Read about the development and value of space exploration.2. Explore the mysteries of the universe and the achievements in space exploration.3. Skillfully use the vocabulary of this text to cultivate self-study ability 4. Develop cooperative learning ability through discussion.1. Enable the Ss to talk about the development and value of space exploration.2. Guide the Ss to summarize the main idea of each paragraph as well as the main idea of the text.3. Help Ss comprehend the main reasons for space exploration. Multi-media, textbook, notebooks.Step 1: Warming up and predictionLook at the title and the pictures of the text and predict what the text will be about?2. What are the main reasons for space exploration?

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."

? Could you offer me some kind of work here?? I don’t want your charity, I just want an honest job.? Careless: I landed in Britain by accident.Step 7:Consolidation.? Find Henry? Roderick and Oliver were I .making a bet when they saw Henry, a poor young man. ? Know Henry? About a month ago, Henry was sailing and later he found himself carried out to sea by a strong wind. Fortunately, he 2.was spotted by a ship. And it was the ship that brought him to 3.England? Offer money to Henry ? Oliver and Roderick gave Henry a letter and told him that there was money in it. They 4.persuaded him to accept it, and made him 5.promise that it wouldn't be opened until 2 o'clock.Step 8:Language pointsa large amount of: a large quantity of; a great deal ofe.g. They bought a large amount of furniture before they moved their new house.make a bet: make an arrangement to risk money, etc. on an event of which the result is doubtful.e.g. We made a bet on the result of the match.permit sb to do something: allow somebody to do somethinge.g. My mother doesn’t permit me to ride in the street after it rained.by accident: as a result of chancee.g. I only found it by accident.stare at: look at somebody or something with the eyes wide open in a fixed gaze( in astonishment, wonder, fear, etc)to be honest: to tell you the truth; to be franke.g. To be honest, I don’t think we have a chance of winning.Step7 Homework:What do you think will happen to Henry?

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.

高斯(Gauss,1777-1855),德国数学家,近代数学的奠基者之一. 他在天文学、大地测量学、磁学、光学等领域都做出过杰出贡献. 问题1:为什么1+100=2+99=…=50+51呢?这是巧合吗?试从数列角度给出解释.高斯的算法:(1+100)+(2+99)+…+(50+51)= 101×50=5050高斯的算法实际上解决了求等差数列:1,2,3,…,n,"… " 前100项的和问题.等差数列中,下标和相等的两项和相等.设 an=n,则 a1=1,a2=2,a3=3,…如果数列{an} 是等差数列,p,q,s,t∈N*,且 p+q=s+t,则 ap+aq=as+at 可得:a_1+a_100=a_2+a_99=?=a_50+a_51问题2: 你能用上述方法计算1+2+3+… +101吗?问题3: 你能计算1+2+3+… +n吗?需要对项数的奇偶进行分类讨论.当n为偶数时, S_n=(1+n)+[(2+(n-1)]+?+[(n/2+(n/2-1)]=(1+n)+(1+n)…+(1+n)=n/2 (1+n) =(n(1+n))/2当n为奇数数时, n-1为偶数

新知探究国际象棋起源于古代印度.相传国王要奖赏国际象棋的发明者,问他想要什么.发明者说:“请在棋盘的第1个格子里放上1颗麦粒,第2个格子里放上2颗麦粒,第3个格子里放上4颗麦粒,依次类推,每个格子里放的麦粒都是前一个格子里放的麦粒数的2倍,直到第64个格子.请给我足够的麦粒以实现上述要求.”国王觉得这个要求不高,就欣然同意了.假定千粒麦粒的质量为40克,据查,2016--2017年度世界年度小麦产量约为7.5亿吨,根据以上数据,判断国王是否能实现他的诺言.问题1:每个格子里放的麦粒数可以构成一个数列,请判断分析这个数列是否是等比数列?并写出这个等比数列的通项公式.是等比数列,首项是1,公比是2,共64项. 通项公式为〖a_n=2〗^(n-1)问题2:请将发明者的要求表述成数学问题.

苏格拉底把装有毒酒的杯子举到胸口,平静地说:“分手的时候到了,我将死,你们活下来,是谁的选择好,只有天知道。”说毕,一口喝干了毒酒。(2) 苏格拉底临死前对一个叫克力同的人说了这样一番话。克力同,我告诉你,这几天一直有一个神的声音在我心中晓喻我,他说:“苏格拉底,还是听我们的建议吧,我们是你的卫士。不要考虑你的子女、生命或其他东西胜过考虑什么是公正。……事实上你就要离开这里了。当你去死的时候,你是个牺牲品,但不是我们所犯错误的牺牲品,而是你同胞所犯错误的牺牲品。但你若用这种可耻的方法逃避,以错还错,以恶报恶,践踏你自己和我们订立的协议合约,那么你伤害了你最不应该伤害的,包括你自己、你的朋友、你的国家,还有我们。到那时,你活着面对我们的愤怒,你死后我们的兄弟、冥府里的法律也不会热情欢迎你;因为它们知道你试图尽力摧毁我们。别接受克力同的建议,听我们的劝告吧。”

今天我说课的题目是《生活与哲学4(必修)》的第二单元第六课第一框题——《人的认识从何而来》下面我将从教材,教法,学法,教学过程,教学反思五个方面来说一说我对本课的认识和教学设想。一、说教材我将从该框题在教材中的地位和作用,教学目标,教学重难点三方面来阐述我对教材的认识。(一)首先是教材的地位和作用;本框题重点论述马克思主义哲学认识论中实践与认识的关系。实践的观点是马克思主义首要和基本的观点,理解实践与认识的关系是把握哲学智慧不可或缺的途径。学好本框题不仅有利于学生从宏观上把握教材各课的联系,而且有利于帮助学生理解马克思主义哲学的本质特征。(二)教学目标是确定教学重点,进行教学设计的基础。依据新课程标准,我确定本课的教学目标有以下三方面:知识与技能:1、识记实践的含义、实践的构成要素、实践的特点。

四.设计反思我在设计本课时,希望通过情境的创设充分再现历史,并利用多媒体辅助教学,破重点、化难点,让学生主动参与到学习过程中,从而突破狭小的教室空间,让学生真正做到感知历史,立足现实,展望未来。自主,交流、合作、探究是课程改革中着力倡导的新型学习方式。课堂教学中如何开展小组合作的探究学习存在着很多困难,首先是课堂教学时间有限,如何体现面向全体,给每个学生以机会?再次,历史问题的讨论只能依托于史料才能使讨论不沦为空谈,课堂上通过网络提供大量的史料(文字、图片或其他),势必不能有充分时间让学生阅读分析。如何解决这些问题呢?措施一:要形成较固定的历史学习合作小组。选定一位同学担任组长,负责协调措施二:要设置有利于学生探究的问题情境措施三:要把课堂教学与课外学习结合起来。在课前就印发相关的材料,或引导学生去查阅相关的资料,让学生有个充分的阅读、思考、交流的时间,是保证课堂上小组交流能成功实现的一个前提

教学过程:(一)导入:课前放《爱的奉献》歌曲,同时不断播放一些有关“爱”的主题的图片,渲染一种情感氛围。师说:同学们,谁能说说这组图片的主题应该是什么?生(七嘴八舌):母爱,不对是亲情……是友情、还有人与人互相帮助……那组军人图片是说保卫国家,应该是爱国……那徐本禹和感动中国呢?…………生答:是关于爱的方面师说:不错,是关于爱的方面。那么同学们,今天就以“爱的奉献”为话题,来写一篇议论文如何?生答:老师,还是写记叙文吧。生答:就是,要不议论文写出来也象记叙文。师问:为什么?生答:老师,这个话题太有话说了,一举例子就收不住了,怎么看怎么象记叙文。生答:就是,再用一点形容词,就更象了。众人乐。师说:那么同学们谁能告诉我,为什么会出现这种问题?一生小声说:还不是我们笨,不会写。师说:不是笨,也不是不会写,你们想为什么记叙文就会写,一到议论文就不会了,那是因为同学们没有明白议论文中的记叙与记叙文中的记叙有什么不同,所以一写起议论文中的记叙,还是按照记叙文的写法写作,这自然就不行了。那好,今天我们就从如何写议论文中的记叙讲起。

一、说教材(一)、教材内容《古代中国的发明和发现》是人教版高中历史必修三第三单元第一课内容,本课教材主要从五个方面的典型事例向学生介绍了古代中国几千年的科技成就。本课一方面展示了古代中国人民的勤劳智慧以及对世界文明发展作出的巨大贡献,另一方面也提出了一个重大问题引起学生的思考,即造成中国科技在近代落后的原因是什么。此外、本课在教材中具有承上启下的地位和作用,前承中国传统文化主流思想,后启现代中国科学技术的发展。根据课标要求和教材内容,我将本课的三维目标确定如下:(三)教学目标(1)知识与能力:掌握中国古代科技进步的基础知识,特别是四大发明。认识古代中国四大发明对世界文明发展的贡献,以及取得重大成就的原因。⑵过程与方法:通过指导学生课前阅读课本,在课堂上进行问题探究、实验体验以及历史比较,学会总结归纳。

首先引导回顾细胞质内各个细胞器的分工协作、产生分泌蛋白的过程;同时思考:为什么这些细胞器可以这样有条不紊的密切协作?这中间有没有专门起协调和控制作用的部门?从而导入本节内容。通过学生小组讨论及师生共同分析“资料分析”中的4个实验,总结出细胞核的功能,即细胞核是遗传信息库,控制细胞代谢和遗传的功能。在此基础上,向学生举出克隆羊多莉的实例,加强理解。设问:那么细胞核为什么能成为细胞代谢和遗传的控制中心?要弄清这个问题,我们必须从细胞核的结构中寻找答案,从而引出细胞的结构。在这部分,引导学生思考以下几个问题:(1)细胞核能控制细胞的遗传,说明其应该有什么物质?(2)含有DNA的结构如线粒体、叶绿体,它们的外面都有什么相同的结构?(3)细胞核能控制细胞,肯定能与外界联系,如何能办到?(4)学习RNA的分布时,RNA主要分布在细胞质,少量还分布在哪里呢?
