    ②内燃机的发明推动了交通运输领域的革新。19世纪末,新型的交通工具——汽车出现了。1885年,德国人卡尔·本茨成功地制成了第一辆用汽油内燃机驱动的汽车。1896年,美国人亨利·福特制造出他的第一辆四轮汽车。与此同时,许多国家都开始建立汽车工业。随后,以内燃机为动力的内燃机车、远洋轮船、飞机等也不断涌现出来。1903年,美国人莱特兄弟制造的飞机试飞成功,实现了人类翱翔天空的梦想,预告了交通运输新纪元的到来。③内燃机的发明推动了石油开采业的发展和石油化学工业的产生。石油也像电力一样成为一种极为重要的新能源。1870年,全世界开采的石油只有80万吨,到1900年猛增至2 000万吨。(3)化学工业的发展:①无机化学工业:用化学反应的方式开始从煤焦油中提炼氨、笨、等,用化学合成的方式,美国人发明了塑料,法国人发明了纤维,瑞典人发明了炸药等。

    Step 3 Analyzing article structureActivity 31. Teachers raise questions to guide students to analyze the chapter structure of this diary and think about how to describe the festival experience. (1)What should be included in the opening/body/closing paragraph(s)?(2)How did the writer arrange his/her ideas?(3)What kind of interesting details did the writer describe?(4)How did the writer describe his/her feelings/emotions during the event?2. Students read and compare the three sentence patterns in activity 2. Try to rewrite the first paragraph of the diary with these three sentence patterns. After that, students exchange corrections with their partners. Such as:●This was my first time spending three days experiencing the Naadam Festival in China’s Inner Mongolia Autonomous Region and it was an enjoyable and exciting experience. ●I'll never forget my experience at the Naadam Festival because it was my first time to watch the exciting Mongolian games of horse racing, wrestling, and archery so closely. ●I'll always remember my first experience at the Naadam Festival in China’s Inner Mongolia Autonomous Region because it was so amazing to spend three days witnessing a grand Mongolian ceremony. Step 4 Accumulation of statementsActivity 41. Ask the students to read the diary again. Look for sentences that express feelings and emotions, especially those with the -ing form and the past participle. Such as:● …horse racing, wrestling, and archery, which are all so exciting to watch. ● some amazing performances● I was surprised to see…● I was a little worried about. . . ● feeling really tiredOther emotional statements:●I absolutely enjoyed the archery, too, but the horse races were my favourite part. ●I'm finally back home now, feeling really tired, but celebrating Naadam with my friend was totally worth it. ●He invited me back for the winter to stay in a traditional Mongolian tent and cat hot pot. I can’t wait!2. In addition to the use of the -ing form and the past participle, the teacher should guide the students in the appreciation of these statements, ask them to memorize them, and encourage them to use them reasonably in writing practice.

    新人教版高中英语必修3Unit 4 Space Exploration-Listening&Speaking&Talking教学设计二

    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

    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.

    人教版高中政治必修4关于世界观的学说说课稿(二)

    一、教材分析1、本框题在教材中的地位。本框题教材所处的地位及联系:《关于世界观的学说》是人教版2004年12月第一版教材高二政治必修4第一单元第二框题,在这之前学生已经学习了生活处处有哲学的内容,了解了哲学与我们的生活息息相关,这为过度到本框题的学习起到了铺垫的作用。本框题又是学生进入哲学的入门,因而它在生活与哲学中具有不容忽视的重要地位。学好本框题,为学生从总体上对哲学的理解,为以后学好哲学做了良好的铺垫作用。本框题是进入哲学与生活不可缺少的部分,也学生的学习生活常常遇到的问题。2、教学目标:1. 知识目标:(1)哲学的含义;(2)哲学与世界观的关系;(3)哲学与具体科学知识的关系。2. 能力目标:(1)通过对哲学与世界观、方法论、具体知识三对关系的分析,培养辩证思维的能;(2)通过对身边生活事例、哲理故事、哲学家观点的体悟,培养分析问题的能力;

    ②关于哲学的第二个问题是——思维和存在有没有同一性解释同一性——就是说意识(思维)能否正确认识物质(存在)的问题。(让学生表达他们自己的意见)总结得出三种看法——认为意识(思维)可以正确认识物质(存在)的,属于可知论者;凡是认为意识(思维)不能正确认识物质(存在),属于不可知论者。当然也有些同学是两者观点都有,这种同学我们把他称为不彻底的不可知论者。2、为什么思维和存在的关系问题是哲学的基本问题(1)它是人们在生活和实践活动中首先遇到和无法回避的基本问题(举例说明问题,吃饭的时候吃什么菜,学习计划与学习的实际等等)结合教材P10探究进行讲解举例:11月31日请全班同学吃雪糕,吃完后再去肯德基大吃一顿,之后再到卡拉OK唱通宵——不切实际,因为11月并没有31日。(2)它是一切哲学都不能回避、必须回答的问题(不同的回答,直接决定着哲学的不同发展方向。)

    本节课标解读:1.说明以种植业为主的农业地域类型的形成条件及特点;2.说出商品谷物农业的分布范围,说明商品谷物农业的形成条件及特点。内容地位与作用:农业是受自然环境影响最大的产业。农业是发展历史最悠久的产业,随着社会的发展和进步,社会环境对农业的影响越来越大。以季风水田农业为主的农业地域类型,主要体现自然环境对农业地域形成的影响;商品谷物农业则体现了社会环境对农业地域形成的影响。本节内容包括两部分内容,一个是季风水田农业,主要分布在亚洲季风区;一个是商品谷物农业,主要分布在发达国家。教材文字内容不多,配备了大量的地图和景观图。因此,在教学过程中要充分组织学生查阅地图,挖掘地理信息,培养分析能力。分析农业区位因素时,必须从自然因素和社会经济因素两个方面去分析,找出优势区位因素来。

    国旗下讲话:《告别陋习,崇尚文明》(二)

    有人说:“如果你失去了今天,你不算失败,因为明天会再来;如果你失去了金钱,你不算失败,因为人生的价值不在金钱;但是如果你失去了文明,沾染了陋习,那你就是彻彻底底的失败,因为你已经失去了做人的真谛。”没错,我们做人的行为准则就是要讲究文明,抛弃陋习。我们祖国素以“礼仪之邦”著称于世,“孔融四岁让梨”的故事更是家喻户晓。现在之所以重提文明礼仪,那是因为我们在接受教育的时候,把对文化知识的学习放在了相对重要的位子,加上受外界的一些不良影响而忽略了社会公德、文明习惯的养成,而这恰恰从本质上体现了一个人的思想品质。文明就是我们素质的前沿,拥有了它,我们就拥有了宝贵的财富。首先,要培养自己高尚的心灵,从心里深深的扎根,在日常生活的每一言每一行都靠心来约束自己。其次,要在实践中用文明道德标准规范自己,做到谈吐文明,礼貌待人,讲究卫生。
