  • 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.

  • 人教版新课标高中地理必修2第一章第二节人口的空间变化教案

    1.促使美国成为一个移民国家的因素是:①美洲属于未开发的新大陆,需要大量的劳动力;②欧洲失业工人和破产农民增加,人们为了追求更好的经济待遇迁往美洲;③新航线的开辟为人们顺利迁移扫除了障碍;④殖民扩张是人口迁移的促进因素,加快了人口迁移的过程。导致美国人口在本土范围内频繁迁移的原因,归纳起来有:第一次人口迁移是战争因素,第二次是城市化;第三次是自然环境、经济环境的变化;第四次是经济格局的变化,即西部和南部新资源的发现和新兴工业的发展。2.我国古代的人口迁移,深受统治者及其行政力量的束缚。封建帝王为了加强本国的经济和军事实力,对人口迁移严加控制。只有当战乱发生的时候,这种控制才得到削弱,人们为了躲避战乱,寻找安定的生活环境,不得不进行大规模的迁移。我国近几十年的人口迁移主要是由生产资料和劳动力数量上的地区分布不平衡造成的,是经济因素在起主导作用,与古代的人口迁移截然不同。

  • 《一个消逝了的山村》说课稿 2021—2022学年统编版高中语文选择性必修下册

    这几段内容传达出的是“要敬畏生命,尊重生命;更要敬畏大自然,尊重大自然,爱护大自然”的主旨内涵,因此让学生通过自由朗读的方式,再次体会冯至对这个消逝了的山村的细致的美好的描绘,感悟冯至传达出的对生命,对自然的理解和思考。5.最后一个自然段的解读依然是交给学生,先齐读课文,再让学生自主分享自己的体会或疑惑。但在这一环节我也设计了两个我认为必须解答的两个问题,一是怎么理解“在风雨如晦的时刻”;二是“意味不尽的关联”是指什么。我认为这两个问题一个涉及到写作背景,一个涉及到对全文主旨的一个整体把握,能够进一步帮助学生理解散文的深刻内涵和主旨,让学生有意识的在阅读散文过程中通过背景知识进行理解。既尊重学生的个性化解读,又能够让学生有意义学习,完成预设的教学目标。如果学生没有提到这两处,那我就需要做出补充。

  • 新人教版高中英语必修3Unit 1 Festivals and Celebrations-Listening &Speaking&Talking教学设计

    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 story was quite successful in achieving its purpose, and I liked it because it had a clear moral.However, while the moral of the story is clear, the actions of the king seemed pointless to me, because none of the characters in the story learnt anything.
