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.

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.
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. Use this checklist to help your partner revise his/her draft.1.Does the writer explain why he/she changed/wanted to change?2.Does the writer tell how the changes have improved or will improve his/her life?3.Is the text well-organised?4.Does the writer use words and expressions to show similarities and differences?5.Are there any grammar or spelling errors?6.Does the writer use correct punctuation?
Example:One day, a poor boy who was trying to pay his way through school by sending newspapers door to door found that he only had one dime(一角)left. He was so hungry that he decided to beg for a meal at the next house.However, he lost his nerve when a lovely young woman opened the door. Instead of a meal he asked for a drink of water. She thought he looked hungry so she brought him a large glass of milk. He drank it slowly, and then asked, “How much do I owe you?” “You don’t owe me anything,” she replied, “Mother has taught me never to accept pay for a kindness.” “Then I thank you from the bottom of my heart.” With these words, Howard Kelly left that house.Years later the woman became badly ill and was finally sent to the hospital in a big city. Dr. Howard Kelly, now famous, was called in. When he heard the name of the town she came from, a strange light filled his eyes. Dressed in his doctor’s clothes, Dr. Kelly went into her room and recognized her at once. From that day on, he gave special attention to her, and decided to do his best to save her life.At last the woman was saved. Dr. Kelly asked the business office to pass the final bill to him. He looked at it and then wrote something on the side. The bill was sent to the woman’s room. She was afraid to open it because she was sure that it would take the rest of her life to pay for it off. Finally she looked, and the note on the side of the bill caught her attention. She read these words: “Paid in full with a glass of milk, Dr. Howard Kelly.” Tear of joy flooded her eyes.

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.

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
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;
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?

演示实验1、将一张纸和一张金属片在同一高度同时释放,结果金属片先着地。教师不发表意见,继续做实验。分别将实验内容和实验结果板书在黑板上。2、将刚才的纸片紧紧捏成一团,再次与硬币同时释放,结果两者几乎同时落地。3、将两个完全一样的纸片,一个捏成团,一个平展,则纸团下落快。师:物体下落快慢是由质量决定吗?生:不是的!师:为什么这样说?生:第2个实验和第三实验都说明了这个问题,特别是第3个问题,质量一样却下落有快慢之分。师:那你现在觉得物体下落快慢由什么因素决定呢?生:我想应该是空气阻力。猜想师:如果影响物体下落快慢的因素是空气阻力,那么在没有空气阻力,物体的下落快慢应该是一样的,这种猜想是不是正确呢?我们来做一个实验验证一下。
生:还可以从表盘上直接读出公里里程.师:日常生活中的“速度”有时指速度,也有时指速率,要看实际的物理情景。[讨论与交流]甲、乙两位同学用不同的时间围绕操场跑了一圈,都回到了出发点,他们的平均速度相同吗?怎样比较他们运动的快慢?学生讨论,体验平均速度的缺陷,引入平均速率。生1:位移都是零,平均速度等于位移跟发生这段位移所用时间的比值,所以他们的平均速度都是零。生2:即使一位同学站在原地不跑,他的平均速度也是零啊,可我们运动会上不是这样比快慢的,如果这样,那多不公平啊?师:平均速度v=Δx/Δt,甲、乙的位移都为零,所以他们的平均速度也都等于零.在这里平均速度无法显示他们运动快慢的不同,要用到另一物理量:平均速率.平均速率等于物体运动通过的路程跟所用时间的比值.他们两人通过的路程相同且都不为零,但所用时间不同.显然用时短的运动得快,也就是平均速率大.生:这不是我们初中学过的速度吗?
一、知识与技能1、知道伽利略的理想实验及其主要推理过程和推论,知道理想实验是科学研究的重要方法2、理解牛顿第一定律的内容及意义;理解力和运动的关系,知道物体的运动不需要力来维持。3、理解惯性的概念,知道质量是惯性大小的量度;会用惯性解释一些现象。二、过程与方法1、观察生活中的惯性现象,了解力和运动的关系2、通过实验加深对牛顿第一定律的理解3、理解理想实验是科学研究的重要方法三、情感态度与价值观1、通过伽利略和亚里士多德对力和运动关系的不同认识,了解人类认识事物本质的曲折性2、感悟科学是人类进步的不竭动力[教学重点]1、理解力和运动的关系2、对牛顿第一定律和惯性的正确理解3、理想实验[教学难点]1、力和运动的关系2、惯性和质量的关系[课时安排]1课时[教学过程][引入]
教学重点1.自由落体运动的概念及探究自由落体运动的过程。2.掌握自由落体运动规律,并能运用其解决实际问题。教学难点演示实验和探究实验的技巧及自由落体运动规律的得出.教学过程设计思想:1、 先用游戏激发学生学习兴趣,顺理成章地研究落体运动;2、 通过演示实验让学生自己总结出物体下落快慢不同的主要原因是空气阻力,从而猜想若没有空气阻力会怎样;3、 用牛顿管实验验证猜想,引入了新的理想运动模型:自由落体运动。讲述1971年宇航员做的实验,加深印象;4、 了解地球表面物体下落运动近似成自由落体运动的条件;5、 着手研究自由落体运动的规律,利用打点计时器进行研究,得到结论;6、 总结自由落体运动特点及重力加速度;7、 应用训练
1.这节课以实验为依据,采用控制变量的方法进行研究。这一方法今后在电学、热学的研究中还要用到。我们根据已掌握的知识设计实验、探索规律是物体研究的重要方法。2.定义力的单位“牛顿”使得k=1,得到牛顿第二定律的简单形式F=ma。使用简捷的数学语言表达物理规律是物理学的特征之一,但应知道它所对应的文字内容和意义。3.牛顿第二定律概括了运动和力的关系。物体所受合外力恒定,其加速度恒定;合外力为零,加速度为零。即合外力决定了加速度,而加速度影响着物体的运动情况。因此,牛顿第二定律是把前两章力和物体的运动构成一个整体,其中的纽带就是加速度。四、评价方案及说明1、对科学知识与技能的评价要注重科学内容的理解与应用,而不是单纯记忆。技能的评价目标包括观察技能、实验技能等方面。对科学的技能的评价要尽量融合在科学探究过程的情景中。对科学知识的评价主要从两方面,一是根据学生诊断性练习;二是通过学生作业反映学生掌握情况。
实验目标:1、知道打点计时器的构造和原理,学会使用打点计时器,能根据打出的纸带计算打几个点所用的时间,会计算纸带的平均速度,能根据纸带粗略测量纸带的瞬时速度,认识v-t图象,并能根据v-t图象判断物体的运动情况。2、通过速度测量过程的体验,领悟两个方法:一是用图象处理物理数据的方法;二是极限法或说无限趋近法,加强一个认识,实验是检验理论的标准。实验器材:电源(220v电源或学生电源),打点计时器,纸带,刻度尺(最好是塑料透明的),导线实验准备:1、仔细观察电磁打点计时器和电火花计时器,对照课本,比较它们的异同。2、两类打点计时器的打点时间间隔是多少?3、分析纸带时,如何计算纸带的平均速度。4、严格地说,瞬时速度我们引进测量出来的,你知道用什么方法求出的速度可以代替某点的瞬时速度吗?
猜想:既然物体下落过程中的运动情况与物体质量无关,那么为什么在现实生活中,不同物体的落体运动,下落快慢不同呢?我们能否猜想是由于空气阻力的作用造成的呢?如果没有空气阻力将会怎样呢?学生讨论后回答.三、猜想与假说伽利略认为,自由落体是一种最简单的变速运动.他设想,最简单的变速运动的速度应该是均匀变化的.但是,速度的变化怎样才算均匀呢?他考虑了两种可能:一种是速度的变化对时间来说是均匀的,即经过相等的时间,速度的变化相等;另一种是速度的变化对位移来说是均匀的,即经过相等的位移,速度的变化相等.伽利略假设第一种方式最简单,并把这种运动叫做匀变速运动.四、实验验证实验验证是检验理论正确与否的唯一标准.任何结论和猜想都必须经过实验验证,否则不成理论.猜想或假说只有通过验证才会成为理论.所谓实验验证就是任何人,在理论条件下去操作都能到得实验结果,它具有任意性,但不是无条件的,实验是在一定条件下的验证,而与实际有区别.
