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?

Besides, I must keep mental and physical healthy.Step 7. HomeworkTry to summarize the structure of the article by a mind map.
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.

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."

(1)社会实践是文化创新的源泉实践,作为人们改造客观世界的活动,是一种有目的、有意识的社会性活动。人类在改造自然和社会的实践中,创造出自己特有的文化。离开了社会实践;文化就会成为无源之水、无本之木,人们不可能从事任何有价值的文化创造。◇本课小结:1.关于本课逻辑结构的宏观把握:文化创新的源泉和作用这一问题,教材分三个层次展开论证:一是不尽的源泉,不竭的动力;二是巨大的作用,深刻的意义;三是呼唤文化创新的时代。教材运用辩证方法从文化创新的源泉和作用展开论述。即社会实践是文化创新的源泉,文化创新又推动社会实践的发展和促进民族文化的繁荣。教材关于文化创新的途径问题,从三个层次展开讲述:第一个层次是“继承传统,推陈出新”;第二个层次是“面向世界,博采众长”;第三个层次是“坚持正确方向,克服错误倾向”。三个层次三个角度,着重于分析每一个层次,然后予以归纳总结,即采用了分析归纳法,层次清晰,教学目标明确,既便于传授知识,又便于学生学习时识记、理解和把握。
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.
4.They were going to find someone to take part in their bet when they saw Henry walking on the street outside.[归纳]1.过去将来时的基本构成和用法过去将来时由“would+动词原形”构成,主要表示从过去某一时间来看将要发生的动作(尤其用于宾语从句中),还可以表示过去的动作习惯或倾向。Jeff knew he would be tired the next day.He promised that he would not open the letter until 2 o'clock.She said that she wouldn't do that again.2.表示过去将来时的其他表达法(1)was/were going to+动词原形:该结构有两个主要用法,一是表示过去的打算,二是表示在过去看来有迹象表明将要发生某事。I thought it was going to rain.(2)was/were to+动词原形:主要表示过去按计划或安排要做的事情。She said she was to get married next month.(3)was/were about to+动词原形:表示在过去看来即将要发生的动作,由于本身已含有“即将”的意味,所以不再与表示具体的将来时间状语连用。I was about to go to bed when the phone rang.(4)was/were+现在分词:表示在过去看来即将发生的动作,通常可用于该结构中的动词是come,go,leave,arrive,begin,start,stop,close,open,die,join,borrow,buy等瞬间动词。Jack said he was leaving tomorrow.
3 比一比,谁算得快。38+76+24 (88+45)+124 、拓展560+(140+70)=(□ + □ )+ □ (64+□)+27=64+(□+27)71+68+ □ 你认为 □ 里填什么数会使你的计算简便?怎样简便计算?5、游戏:找朋友。(1) 哪两个同学手上的树叶的和是100?(2) 同桌一个同学说出一个数,另一个同学马上说出一个与它的和是整百、整千的数。【设计意图 :几个层次的练习,为学生提供了具有价值的学习内容,开放学生的思维空间,提高思维含量,学生在观察辨析中比较,在思考对比中升华,促进学生灵活地理解和掌握知识。】(五)、全课总结,引申知识今天这节课我们学习了什么知识?你是怎样获得这些知识的?那么在减法、乘法、除法中,有没有这样的规律呢?课后大家可以继续研究。【及时总结、巩固所学知识,重视学法总结。使学生在自己的整理总结中再次巩固了本节课的重难点。同时为学生以后的学习作好了铺垫】
1.数字编码越来越重要,了解编码的含义,会给人们的生活、工作带来很多的便利。公安机关常常利用一些编码侦破案件。请同学们看个短片,仔细观察,你能找出对破案有用的线索并说出理由吗?生答。是的,公安人员根据这些线索很快将犯罪嫌疑人抓获。2.运用数字或符合来描述事物可以更简洁准确。看到这个号码不用知道名字就能找到这个人。首先请同学们仔细想一想,号码中要体现哪些方面的内容?先自己想再到小组中交流,组长记录下讨论的结果。生讨论结束后师实物出示结果,追问:①其他小组还有什么不同意见吗?集体讨论得出结果:编入入学时间、班级序号、班级学号、性别等。追问:②按什么顺序编排比较合理呢?生讨论得出按入学时间、班级序号、班级学号、性别的顺序。其次学生给自己编号码,师实物出示提问:看到这个号码,你能找到这个人吗?生根据号码找到这个人。
6、改错题出现在练习七中,与以往的要求不同。学生从一年级就已形成先找错,再改错习惯。学习了加减法验算方法后,教材要求用验算的方法先检验是否正确,再改错。(就是重做一遍)这一教学环节,对学生来说有一定的难度。个别学生检验完后,不是改错,而是在验算。教师在巡视时,发现后,一再强调检验是错题后,改错就是重做一遍,可是这一教学环节,还是留有遗憾。7、当学生达到熟练验算后,就要实际应用。在备课时,我个人认为教材以表格形式出现,目的是与高段应用题验算有一定区别(高段应用题验算要求把未知变已知,把已知变未知.)这里以表格形式出现,已知、未知一目了然。通过这一习题的训练,也为今后的学习打下一定的基础。在设计这一教学环节时,我设计了让学生在掌握验算的实际应用后,挑选自己喜欢的水果和同组合作训练。可教材练习七的第8题已剩不多时间,只好指名说验算方法。
(设计意图:让学生充分表述自己的想法,强化学生的应用意识,培养学生解决实际问题的能力。从中发现可能性会随着数量的变化而变化的。)(四)归纳总结,完善认知1、学生汇报学习所得。(使学生体验探索成功的喜悦)2、教师评价学习态度。(让学生感受学习数学我能行)五、板书科学设计简单明了,重点突出,加深对所学知识的理解和掌握。通过以上创新处理,营造宽松的学习氛围,为学生创造联想猜测、动手操作、合作交流、自主探究、解决问题的机会,使学生在“自主——合作——探究”的学习过程中,体验数学探索成功的喜悦,体会到数学课堂充满生命的活力。以上是我对本节课的一些设想,还有待于在实践中去完善,如有不当之处,敬请各位专家评委给予批评和指正。
一、教材分析及学生分析:数学课程标准在各个学段中,安排了“数与代数”、“空间与图形”、“统计与概率”、“实践与综合应用”四个学习领域。其中“统计与概率”中统计初步知识在一、二年级已经涉及,但概率知识对于学生来说还是一个全新的概念,它是学生以后学习有关知识的基础,并且概率问题是一个与社会生活关系密切的重要问题。因此在第一学段中对于“不确定现象”由感性升华到理性认识非常重要。对于三年级的孩子来说,由于他们的年龄和思维特点,他们一般只能在感性的层面理解可能性的知识,因此,在教学中,我们密切关注并考虑学生已有的经验知识,在学生已有的经验体会的基础上,设计各种活动丰富学生的经验积累,从而进行可能性知识的构建。
3、个性展示。《课程标准》把发展学生的符号感作为义务教育阶段的一个重要的数学学习内容。于是在上一个环节中,我继续让学生举例,通过大量的实例,使学生发现这样的例子有很多,总也举不完,再用特定的数已经满足不了这种需要,造成了学生的认知冲突。“怎样表示出所有的例子呢?”启发学生探究新的表达方式,激起学生强烈的探究欲望。紧接着组织学生先在小组里说说自己是怎么想到这样的表达方式的,然后把用不同的符号或字母表示的式子写到黑板上,并追问“为什么可以这样表示?每一个符号或字母表示什么数?”待全部汇报完后,再把这些个性化的符号、字母表示的加法交换律和用具体的数以及语言文字表示的进行比较,让学生谈谈有什么感受?这样,就使学生从具体的情境中抽象出变化规律,发展了学生的符号感,同时使学生感受到用字母表示的优越性,还使学生获得了成功的体验。
(3)补充题:2008年的奥运会在北京举行,小明的爸爸决定去北京观看一些比赛项目,为中国健儿加油。如果坐汽车,每小时行使60千米,4小时可以多少千米?如果坐火车,火车的速度是汽车的2倍,同样的时间可以行使多少千米?这题的第2个问题中蕴含着两种解题思路,让学生说一说、比一比。一种是根据速度×时间=路程的数量关系,先算出变化了的那个因数是多少,再求积。另一种是根据一个因数不变,另一个因数乘以几,原来的积也乘以几解决问题。两种方法得出的积相同,使学生体会积的变化规律是客观存在的普遍规律。『设计理念』在层次分明,形式多样的练习中,通过让学生想一想、填一填、说一说,使学生在规律的应用中逐步加深对积的变化规律的理解。
