  • 人教版高中地理必修2第四章第二節(jié)工業(yè)地域的形成說(shuō)課稿

    人教版高中地理必修2第四章第二節(jié)工業(yè)地域的形成說(shuō)課稿

    下面要針對(duì)工業(yè)地域內(nèi)部的工業(yè)聯(lián)系進(jìn)行講解,這里主要涉及到的是工序上的工業(yè)聯(lián)系。在這段文字的處理上,我會(huì)將鋼鐵、石化、機(jī)械加工等工業(yè)部門(mén)分散成一步一步的工序,便于學(xué)生理解這種工業(yè)上的聯(lián)系方式與構(gòu)造,進(jìn)而對(duì)于工業(yè)的發(fā)育程度這一概念的理解也就相對(duì)簡(jiǎn)單了。緊接著需要講述的是工業(yè)分散的內(nèi)容。工業(yè)分散是建立在現(xiàn)代的交通運(yùn)輸方式和通信技術(shù)與手段上的。它主要針對(duì)的是體積小、重量輕、價(jià)格昂貴的電子產(chǎn)品生產(chǎn)領(lǐng)域,目的是根據(jù)原件的不同性質(zhì)選擇不同的生產(chǎn)地域,利用其各異的優(yōu)勢(shì)條件以節(jié)省開(kāi)支。由于案例都是針對(duì)高科技產(chǎn)品的生產(chǎn)而提出的,因此在這段教材的教學(xué)中我會(huì)注意避免將工業(yè)分散這一現(xiàn)象描述得更為高級(jí)。要讓學(xué)生明白,無(wú)論是工業(yè)集聚還是工業(yè)分散,它們之間是沒(méi)有好壞之分的。最后將進(jìn)行課堂小結(jié),由于本節(jié)內(nèi)容較少且相對(duì)簡(jiǎn)單,可以在最后適當(dāng)添加部分練習(xí)題,重點(diǎn)考察一二兩節(jié)的相關(guān)知識(shí)點(diǎn)。

    人教版高中地理必修2南京的自行車(chē)是多了還是少了說(shuō)課稿

    在學(xué)生回答的基礎(chǔ)上進(jìn)行歸納小結(jié):發(fā)展城市公共交通? 明確道路分工? 合理規(guī)劃停車(chē)場(chǎng)? 減少出行距離? 錯(cuò)開(kāi)出行高峰? 加大城市道路建設(shè)? 進(jìn)行科學(xué)合理的交通管理,重視智能交通系統(tǒng)的建設(shè)提問(wèn):這組同學(xué)在幻燈片中提到城市環(huán)境污染源主要有哪些?城市交通環(huán)境問(wèn)題除了交通工具的尾氣排放帶來(lái)大氣污染外,還會(huì)給城市環(huán)境帶來(lái)什么問(wèn)題?這組同學(xué)基本同意自行車(chē)多是加劇南京空氣污染的間接原因,你同意他們的觀(guān)點(diǎn)嗎?在學(xué)生回答的基礎(chǔ)上,教師進(jìn)行歸納小結(jié):自行車(chē)是一種綠色交通工具,既環(huán)保又經(jīng)濟(jì)。只有當(dāng)它在某些機(jī)動(dòng)車(chē)和非機(jī)動(dòng)車(chē)不分的地段,影響車(chē)輛行駛速度的時(shí)候,它才可能成為加劇空氣污染的間接原因。那么我們針對(duì)交通工具對(duì)環(huán)境造成的影響,除了這組同學(xué)提到的三點(diǎn)解決措施以外,我們還有什么要補(bǔ)充的解決方法嗎?

    在講述細(xì)胞分化的意義時(shí),也可以用實(shí)例來(lái)解決,工廠(chǎng)的生產(chǎn)車(chē)間里不同的工人干著不同的工作,一件產(chǎn)品的產(chǎn)出需要這些工人才能創(chuàng)造出來(lái),一個(gè)生物體就像一個(gè)車(chē)間一樣,不同的細(xì)胞各司其職,相互合作。工人的分工是主管調(diào)解出來(lái)的,而不同細(xì)胞的出現(xiàn)就是細(xì)胞分化的結(jié)果,所以說(shuō),細(xì)胞的分化是生物體發(fā)育的基礎(chǔ)。在講到細(xì)胞全能性的時(shí)候,要多給學(xué)生舉些關(guān)于細(xì)胞全能性的例子,如植物組織培養(yǎng)、克隆技術(shù)等等,讓學(xué)生從實(shí)際的例子中真正的悟出細(xì)胞全能性的含義。此外,還要重視教材中的疑問(wèn),適當(dāng)對(duì)題目進(jìn)行引申,使它的作用更加突出,有利于學(xué)生對(duì)知識(shí)的串聯(lián)、積累、加工,從而達(dá)到舉一反三的效果。怎樣來(lái)解釋細(xì)胞的全能性呢?這主要以講授法來(lái)解釋了,細(xì)胞全能性的體現(xiàn)需要在組織或器官離體后才能體現(xiàn)出來(lái),每個(gè)細(xì)胞都包含著生物體的全套遺傳基因,通過(guò)基因選擇性的表達(dá),使離體的組織或器官通過(guò)分裂和分化逐漸發(fā)育成完整的植株。

    Example:One day, a poor boy who was trying to pay his way through school by sending newspapers door to door found that he only had one dime(一角)left. He was so hungry that he decided to beg for a meal at the next house.However, he lost his nerve when a lovely young woman opened the door. Instead of a meal he asked for a drink of water. She thought he looked hungry so she brought him a large glass of milk. He drank it slowly, and then asked, “How much do I owe you?” “You don’t owe me anything,” she replied, “Mother has taught me never to accept pay for a kindness.” “Then I thank you from the bottom of my heart.” With these words, Howard Kelly left that house.Years later the woman became badly ill and was finally sent to the hospital in a big city. Dr. Howard Kelly, now famous, was called in. When he heard the name of the town she came from, a strange light filled his eyes. Dressed in his doctor’s clothes, Dr. Kelly went into her room and recognized her at once. From that day on, he gave special attention to her, and decided to do his best to save her life.At last the woman was saved. Dr. Kelly asked the business office to pass the final bill to him. He looked at it and then wrote something on the side. The bill was sent to the woman’s room. She was afraid to open it because she was sure that it would take the rest of her life to pay for it off. Finally she looked, and the note on the side of the bill caught her attention. She read these words: “Paid in full with a glass of milk, Dr. Howard Kelly.” Tear of joy flooded her eyes.

    1. 這個(gè)寓言是一個(gè)關(guān)于一位國(guó)王古寓言。 The fable is an old fable about a king.2.作者用這個(gè)故事讓讀者對(duì)于社區(qū)的問(wèn)題負(fù)有個(gè)人責(zé)任的必要印象深刻。The author used the story to impress upon readers with the need to take personal responsibility for problems in the community.3. 這個(gè)故事十分成功的實(shí)現(xiàn)了它的目的。The story was quite successful in achieving its purpose.Step 7 WritingPlease write a review of the story according the outline above.The fable is an old fable about a king who thought his people are lazy, so he put a large stone in the middle of the road and hides and waited to see if anyone will try to move it.The author used this story to impress upon readers with the need to take personal responsibility for problems in the community. 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. Use this checklist to help your partner revise his/her draft.1. Does the writer give a short description of the story ?2. Does the description include the most important details of the story ?3.
