师:很好。由于存在地球大气圈、地球水圈和地表的矿物,在地球上这个合适的温度条件下,形成了适合于生物生存的自然环境。人们通常所说的生物,是指有生命的物体,包括植物、动物和微生物。据估计,现有生存的植物约有40万种,动物约有110多万种,微生物至少有10多万种。据统计,在地质历史上曾生存过的生物约有5亿~10亿种之多,然而,在地球漫长的演化过程中,绝大部分都已经灭绝了。现存的生物生活在岩石圈的上层部分、大气圈的下层部分和水圈的全部,构成了地球上一个独特的圈层,称为生物圈。生物圈是太阳系所有行星中仅在地球上存在的一个独特圈层。课堂小结:地球所有的外部圈层是相互渗透、相互影响,甚至相互重叠的,在太阳和人类生活的参与下,整个地球生机盎然;同时,它们起着保护地球的作用,可以减弱太阳和宇宙辐射对地表的影响,减少宇宙中的陨石对地球表面的撞击。外部各圈中的物质运动和循环,是促使地表物质和形态演变的重要动力。

三维目标:知识和技能 1、了解地球自转和公转的方向及一些基本数据:周期、速度、公转轨道、黄赤交角。2、理解由于地球自转运动造成的昼夜交替、地方时差,掌握时间的有关换算,能正确判断晨昏线。3、理解地球自转和公转的关系,理解太阳直射点的南北移动的过程及其原因,并能演示其运动规律。4、理 解昼夜长短和正午太阳高度的季节变坏纬度变化 。过程与方法 1、通过运用地球仪演示地球的自传和公转现象,学生能够准确的画出夏至日到冬至日太阳照射地球的示意图2、能根据“二分二至日太阳照射地球示意图”分析全球各 地的昼夜长短和正午太阳高度的变化,分析同纬度地区不同季节和不同纬度地区相同季节的昼夜长短和正午太阳高度的变化。

科学家预测,就地区而言,位于低纬度的大部分国家,农作物的产量将减少;而位于高纬度的国家,农作物产量有可能增加。由于不少发展中国家位于低纬度地区,因此,气候变化的这种区域差异性,可能会使发展中国家所面临的问题更为严峻。板书:3全球变暖将加剧水资源的不稳定性与供需矛盾。介绍:全球变暖会影响整个水循环过程,可能使蒸发加大,改变区域降水量和降水分布格局,增加降水极端异常事件的发生,导致洪涝、干旱灾害的频次和强度增加,以及地表径流发生变化。随着径流减少,蒸发增强,全球变暖将加剧水资源的不稳定性与供需矛盾。转折:既然全球变暖会引起很多不利影响,那么作为人类应如何面对这一挑战呢?这就是我们要讨论的第三个问题。板书:三、气候变化的适应对策讨论:请大家阅读结合教材P53气候变化的适应对策部分讨论人类应如何面对全球变暖这一问题 呢?

【转折过渡】除了以上所说的褶皱山和断层山之 外,是否还有其他类型的山脉呢?试举一例说明。【学生思考后回答】有,如富士山属于火山。【教师总结】同学们回答的很好,还有火山,那么火山是如何形成的呢?这就是我们要研究的下一个问题。【板书】3、火山【指导读书】请同学们阅读教材P81思考:①玄武岩高原和火山有什么联系与区别? ②火山由哪几部分构成的?③火山的规模是否相同?【学生回答】①联系:玄武岩高原和火山都是由于处于地下深处的岩浆,在巨大的压力作用下,有时候会沿着地壳的薄弱地带喷出地表而形成的。区别:玄武岩高原是岩浆沿着地壳的线状裂隙流出,往往比较宽广。如哥伦比亚高原。火山是岩浆沿着地壳的中央喷出口或管道喷出。如我国长白山的主峰。②火山由火山口和火山锥两部分组成。③火山的规模大小不一,大火山的相对高度可达4 000~5 000米,火山口直径为数百米;小火山的相对高度不及100米。

当时,不只发生了太阳风暴,同时还有其它的现象发生,导致灾难巨大。 如果,这些现象单独地发生,结果就会是另外一个样子。正是由于这些因素综合起来,1859年的太阳风暴,才在人类历史上留下了浓墨重彩的一笔。太阳磁暴开始干扰通信日本卫星首个被“击中”日本航天机构29日声明,受强烈的太阳磁暴影响,28日晚,日本“儿玉(Kodama)”通讯卫星信号中断。 据美联社报道,在太阳黑子活动减弱后,“儿玉”通讯卫星恢复正常运转。 美欧研究人员28日发布新闻公告称,太阳当天发生了一次强烈的耀斑爆发,预示着新一轮太阳风暴将在今后一两天内抵达地球,地球上的通信等设施可能会因此受到部分干扰。与这次耀斑爆发相伴,太阳表面还产生了一股强大的日冕物质喷射,方向几乎直冲地球。研究人员说,喷射产生的带电粒子流正以约每小时750万公里的速度奔地球而来,其与地球磁场作用后可能会形成比较强烈的地磁暴,使地球两极出现极光,并可能对卫星运行和通信等造成干扰。

1.归纳珠江三角洲发展基塘生产有利的地理条件。珠江三角洲地势低平,河网密布,降水充沛。北回归线从珠江三角洲的北部穿过。珠江三角洲地区发展基塘农业生产有利条件可以结合材料,归纳为三个方面:地形、气候、市场(当地和海外)。2.基塘生产将哪些产业联系起来?哪些副产品(或废弃物)被充分利用起来?这种联系对农村经济发展有什么作用?基塘生产环节将种植业(桑、蔗等)、养殖业(养蚕、养鱼)、工业(丝厂、糖厂)等几种产业紧密的联系在一起。在此环节中,塘泥、蚕沙(蚕屎)、蚕蛹、缫丝、滤泥、蔗叶等副产品被充分的回收利用。养蚕业、蔗糖加工业同塘鱼养殖业紧密结合,作为一种综合的经营,几者之间相互依存、相互促进、扬长补短,有机地循环联系起来。基本上解决了桑、蔗的肥料和蚕、鱼的饲料问题。不仅养蚕、蔗糖加工和养鱼生产稳定,而且成本也大大降低。

角色扮演:学生扮演政府官员、热带丛林土著居民、 世界环保组织官员、开发商等角色,从角色的立场讨论亚马孙河流域热带雨林的开发活动规则: 每个小组认领一种角色,用5分钟的时间讨论和整理思路,然后推荐一位代表做中心发言,小组的其他同学可以随时补充。发言时请说 明所扮演的角色,尽可能多的发表建设性意见。如果需要,可以上台展示材料【学生互动】 风云辩论:雨林破坏谁之错?正方观点:雨林破坏,亚马孙地区 的国家和 居民应负主要责任反方观点: 雨林破坏,发达国家应负主要责任 【师生小结】 雨林的开发,既有发展中国家经济的需要,也有发达国家国际市场的牵动。保护雨林,是全人类的共同责任,尤其发达国家应该承担更多的责任。保护亚马逊雨林符合长远利益和全球利益。但这与雨林所在地国家的发展产生了矛盾,如何解决之一矛盾是雨林开发与保护的关键。【过渡承转】 绿色和平组织警告说,如果不采取有效措施制止对森林的破坏,80年内热带雨林可能完全从地球上消失。开发还是保护?这是雨林的两种前途,也

1.萨赫勒地区位于撤哈拉沙漠的南缘。请根据下面的图文资料,并联系已学知识,分析萨赫勒地区的气候等自然特征,并说明荒漠化的潜在自然因素。点拨:资料表明萨林勒地区正处于干旱与半干旱、热带沙漠与热带草原的过渡地带;津德尔是其中有代表性的居民点,其月均温都在22℃以上,甚至达到33℃,可想而知其蒸发量是巨大的。在降水方面,这里的年降水量不足500毫米,且基本集中在夏季,特别是7、8两个月。以其有限的而且特别集中的降水状况与其全年的高温、高蒸发量相比,确实是个容易产生环境问题的敏感地区。客观上,这里就潜在着荒漠化的自然因素,这是本地区的地理位置和当地的水热条件所决定的。2.气候的严酷性决定了萨赫勒地区的传统经济以自给性质的游牧业为主。20世纪以来,随着沿岸国家人口和经济的发展及本区交通条件的改善,这里的传统游牧经济向商品性的定居牧业经济转化。

The theme of this section is “Talk about festival activities and festival experiences”.Festival and holiday is a relaxing and interesting topic for students. This part talks about the topic from the daily life of students’. In the part A ---Listening and Speaking, there are three conversations among different speakers from three countries(Japan, Rio and China), where the speakers are participating in or going to participate in the festivals and celebrations. So listening for the relationship among them is a fundamental task. Actually, with the globalization and more international communication, it is normal for Chinese or foreigners to witness different festivals and celebrations in or out of China. In the Conversation 1, a foreign reporter is interviewing a Japanese young girl who just had participated in the ceremony of the Coming-of-Age Day on the street and asking her feeling about the ceremony and the afterwards activities. Conversation 2, Chinese girl Li Mei is witnessing the Rio Carnival for the first time, and her friend Carla gives her some advice on the costumes which enables her to match with the carnival to have a good time. Conversation 3, a Chinese guide is showing a group of foreign visitors around the Lantern Festival and introducing the customs of the festival to them. The three conversations have a strong vitality and insert the festival and cultural elements from different countries. So perceiving the festivals and cultures from different countries is the second task. At the same time, the scripts also insert the targeted grammar --- v-ing as attributive and predicative, which students can perceive and experience in a real context and make a road for the further study. That is the third task. In the Part B--- Listening and Talking, the theme is “Talk about festival experience”, which is the common topic in our daily conversations. During the conversation, Song Lin, a Chinese student, asked Canadian friend Max about how to spend Christmas. In the conversation, Song Lin talked about experience and the feelings during the Chinese Spring Festival, during which there are not only some enjoyable things but some unpleasant things. After the listening, perhaps students find there are some similarities between Christmas and the Chinese Spring Festival as there are some differences in the origins and celebrations. For example, people always visit friends and relatives, decorate their houses, have a big dinner together, chat and give presents to each other.

The topic of this part is “Write about your festival experience”.During the Listening and Speaking and Talking, students are just asked to say out their festival experiences such as the Spring Festival, Mid-autumn Day, but this part students will be asked to write down their own festival experiences. During the reading part, it introduces the Naadam Festival in Inner Mongolia Autonomous Region, which can give students a good example to imitate. Students not only learn the festival, but touch and feel the Inner Mongolian’s character, the spirit and cultural atmosphere, which can help students form the cultural awareness and learn to enjoy and value the diversity of Chinese culture.Concretely, the dairy tells the experience that the author spent the Naadam Festival in Inner Mongolia Autonomous Region with his/her friend. The structure is clear. In the opening paragraph, it introduces the topic of the Naadam Festival and the whole feeling. Then it introduces the items of the festival like the ceremony, wrestling and horse racing. Finally, it summarizes this experience. Because this part is a travel journal, we must guide students pay more attention to these details: 1. use the first person. 2. use the past tense to tell the past thing and use the present or future tense to describe the scenery. 3. use the timeline to tell the development. 4. be careful for the author’s psychology, emotion and feeling, etc.1. Read quickly to get main idea; read carefully to get the detailed information about Naadam Festival.2. Learn the structure of the reading article and language.3. Write an article about a festival experience4. Learn to use the psychology, emotions and feeling in the writing.1. Write an article about a festival experience.2. Use the structure of the reading article and language.

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!

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. You’ll find Chinese culture is much more diverse than you thought it was.Justin:This all sounds great, thanks.

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.

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.
