    人教版高中地理必修3資源的跨區(qū)域調(diào)配—以我國的西氣東輸為例說課稿

    由于這部分知識已要求學(xué)生在課前收集相關(guān)資料探討分析,,現(xiàn)在提供機(jī)會讓他們進(jìn)行交流,充分發(fā)表各自的見解。所以,學(xué)生對這個(gè)知識掌握起來并不難。所以,我對這部分內(nèi)容不做太多的講解,只要做進(jìn)一步的梳理,加深學(xué)生的理解即可。 第三是小結(jié)環(huán)節(jié) 在學(xué)生對西氣東輸工程的原因掌握之后進(jìn)入的是小結(jié)環(huán)節(jié),這里我進(jìn)一步提出問題:在西氣東輸工程段的建設(shè)中有沒有什么難關(guān)? 通過西氣東輸?shù)碾y度了解,間接的表現(xiàn)我國的科技的發(fā)展,增加學(xué)生的愛國情,同時(shí)也說明西氣東輸?shù)慕ǔ梢灿屑夹g(shù)這一原因。從而也完成了本課時(shí)的小結(jié)。 第四環(huán)節(jié)是作業(yè)布置 在這里要求學(xué)生課后預(yù)習(xí)本課剩下的內(nèi)容:思考西氣東輸對區(qū)域發(fā)展的影響以及為何要實(shí)施資源的跨區(qū)域調(diào)配。通過這樣的問題一方面為下節(jié)課學(xué)習(xí)奠定基礎(chǔ),另一方面體現(xiàn)本課學(xué)習(xí)從“個(gè)”到“類”從特殊到一般的過程。

  • 第九周國旗下講話稿:堅(jiān)持夢想

    第九周國旗下講話稿:堅(jiān)持夢想

    尊敬的各位老師、親愛的同學(xué)們:大家早上好!今天我演講的題目是“堅(jiān)持夢想”大家都知道古希臘著名哲學(xué)家蘇格拉底,曾對同學(xué)們說,我們來做甩手游戲,就是把手使勁往前甩三百下,再往后甩三百下,但要求每天都做,同學(xué)們紛紛說游戲容易,保證能做好,一星期后,蘇格拉底問同學(xué)們完成得怎么樣?同學(xué)們?nèi)寂e起了手,一個(gè)月后,當(dāng)蘇格拉底再統(tǒng)計(jì)時(shí),全班還有90%的同學(xué),一年后,當(dāng)蘇格拉底再向大家了解時(shí),只有一位同學(xué)舉起手,他就是后來成為大哲學(xué)家的柏拉圖。這個(gè)甩手游戲從動作上看很簡單,但每天堅(jiān)持,卻不是一件容易的事,它需要持之以恒,它需要有始有終,絕不能半途而廢,學(xué)習(xí)也是認(rèn)準(zhǔn)自己的努力目標(biāo),堅(jiān)持不懈地努力不斷地鼓勵自己這樣我們就會體驗(yàn)到成功的喜悅和收獲的快樂。

    反思感悟用基底表示空間向量的解題策略1.空間中,任一向量都可以用一個(gè)基底表示,且只要基底確定,則表示形式是唯一的.2.用基底表示空間向量時(shí),一般要結(jié)合圖形,運(yùn)用向量加法、減法的平行四邊形法則、三角形法則,以及數(shù)乘向量的運(yùn)算法則,逐步向基向量過渡,直至全部用基向量表示.3.在空間幾何體中選擇基底時(shí),通常選取公共起點(diǎn)最集中的向量或關(guān)系最明確的向量作為基底,例如,在正方體、長方體、平行六面體、四面體中,一般選用從同一頂點(diǎn)出發(fā)的三條棱所對應(yīng)的向量作為基底.例2.在棱長為2的正方體ABCD-A1B1C1D1中,E,F分別是DD1,BD的中點(diǎn),點(diǎn)G在棱CD上,且CG=1/3 CD(1)證明:EF⊥B1C;(2)求EF與C1G所成角的余弦值.思路分析選擇一個(gè)空間基底,將(EF) ?,(B_1 C) ?,(C_1 G) ?用基向量表示.(1)證明(EF) ?·(B_1 C) ?=0即可;(2)求(EF) ?與(C_1 G) ?夾角的余弦值即可.(1)證明:設(shè)(DA) ?=i,(DC) ?=j,(DD_1 ) ?=k,則{i,j,k}構(gòu)成空間的一個(gè)正交基底.

    The topic of this part is “Discover the reasons for festivals and celebrations.The Listening & Speaking & Talking part aims at talking about the experiences and feelings or emotions about the festivals and celebrations. This section aims at detecting the reason why the people celebrate the festivals, the time, the places, the types and the way of celebrations. It also explains why some traditions in the old celebrations are disappearing, like the firecrackers in the big cities and some new things are appearing like the prosperity of business or commerce. 1. Students can talk about what festivals they know and the reasons and the way of celebrating them.2. Students should learn the reading skills such as the headline and get the topic sentences, the structures of articles.3. Students can understand the past, the present situation of some festival around the world and why there are some changes about them. 4. Students can have the international awareness about the festivals.1. Students should learn the reading skills such as the headline and get the topic sentences, the structures of articles.2. Students can understand the past, the present situation of some festival around the world and why there are some changes about them.Step 1 Lead in---Small talkWhat festival do you like best ? Why ?I like the Spring Festivals because I can set off the fireworks, receive the lucky money and enjoy the Gala with my families.Step 2 Before reading---Pair workWhy do people celebrate different festivals ?The Spring Festivals is to celebrate the end of winter and the coming of spring and new life.The Mid-autumn Day is to celebrate the harvest and admire the moon.

    新人教版高中英語必修3Unit 1 Festivals and Celebrations-Listening &Speaking&Talking教學(xué)設(shè)計(jì)

    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. For this reason, I think there are better stories that can be used to impress upon people with the need for personal responsibility.Step 8 Pair workExchange drafts with a partner.
