“蛟龍?zhí)枴鄙顫撈鞯目傇O(shè)計師——中船重工第七〇二研究所的徐芑南,他先后三次被評為江蘇省和無錫市勞模,曾被評為上海市科技功臣,有十幾個國家、部、省、市級科技進步獎項與他的名字相聯(lián)。在徐芑南眼中,這些都只是“副產(chǎn)品”,為國家設(shè)計出最需要的潛水器,讓中國具備從“淺藍”走向“深藍”的能力,這才是他最大的愿望。每當(dāng)說到大洋的海底世界,徐芑南的語速快了起來:“海底有好多資源,等著我們?nèi)グl(fā)現(xiàn)、去利用,我們不能落在別人的后面!”海底有石油,海底有許多未知的生物,還有錳結(jié)核、鈷結(jié)殼、熱液硫化物……“蛟龍?zhí)枴钡牧㈨椖康木褪菫榱颂矫魃衩氐纳詈J澜?,造福人類。探究活動二:結(jié)合材料和教材,闡述創(chuàng)新與人類思維方式變革的關(guān)系。(設(shè)計意圖)通過學(xué)生們感興趣的材料,對本課的教學(xué)難點加以突破。

②關(guān)于哲學(xué)的第二個問題是——思維和存在有沒有同一性解釋同一性——就是說意識(思維)能否正確認識物質(zhì)(存在)的問題。(讓學(xué)生表達他們自己的意見)總結(jié)得出三種看法——認為意識(思維)可以正確認識物質(zhì)(存在)的,屬于可知論者;凡是認為意識(思維)不能正確認識物質(zhì)(存在),屬于不可知論者。當(dāng)然也有些同學(xué)是兩者觀點都有,這種同學(xué)我們把他稱為不徹底的不可知論者。2、為什么思維和存在的關(guān)系問題是哲學(xué)的基本問題(1)它是人們在生活和實踐活動中首先遇到和無法回避的基本問題(舉例說明問題,吃飯的時候吃什么菜,學(xué)習(xí)計劃與學(xué)習(xí)的實際等等)結(jié)合教材P10探究進行講解舉例:11月31日請全班同學(xué)吃雪糕,吃完后再去肯德基大吃一頓,之后再到卡拉OK唱通宵——不切實際,因為11月并沒有31日。(2)它是一切哲學(xué)都不能回避、必須回答的問題(不同的回答,直接決定著哲學(xué)的不同發(fā)展方向。)
一、教材分析1、本框題在教材中的地位。本框題教材所處的地位及聯(lián)系:《關(guān)于世界觀的學(xué)說》是人教版2004年12月第一版教材高二政治必修4第一單元第二框題,在這之前學(xué)生已經(jīng)學(xué)習(xí)了生活處處有哲學(xué)的內(nèi)容,了解了哲學(xué)與我們的生活息息相關(guān),這為過度到本框題的學(xué)習(xí)起到了鋪墊的作用。本框題又是學(xué)生進入哲學(xué)的入門,因而它在生活與哲學(xué)中具有不容忽視的重要地位。學(xué)好本框題,為學(xué)生從總體上對哲學(xué)的理解,為以后學(xué)好哲學(xué)做了良好的鋪墊作用。本框題是進入哲學(xué)與生活不可缺少的部分,也學(xué)生的學(xué)習(xí)生活常常遇到的問題。2、教學(xué)目標(biāo):1. 知識目標(biāo):(1)哲學(xué)的含義;(2)哲學(xué)與世界觀的關(guān)系;(3)哲學(xué)與具體科學(xué)知識的關(guān)系。2. 能力目標(biāo):(1)通過對哲學(xué)與世界觀、方法論、具體知識三對關(guān)系的分析,培養(yǎng)辯證思維的能;(2)通過對身邊生活事例、哲理故事、哲學(xué)家觀點的體悟,培養(yǎng)分析問題的能力;

點撥:旅游地旅游資源的特色不同,可以安排的旅游活動是不一樣的,直接影響對旅游者的吸引力。因此,出游前首先就需要收集旅游地旅游資源的類型、主要游覽景區(qū)、景點的特色等情況。旅游地的時空可達性直接關(guān)系到旅游者從出發(fā)地到旅游地,然后再返回出發(fā)地的費用和時間。一般來說,居住地與旅游地之間的空間距離過大,會使旅行的時間過長、旅行費用過高,經(jīng)濟距離增加,相應(yīng)地降低了旅游者的出游能力。而居住地與旅游地相距遙遠,也意味著兩地之間巨大的環(huán)境差異,這會增加對游客的吸引力。旅游服務(wù)設(shè)施和條件,如旅游交通方式及工具、旅游住宿條件、旅游餐飲的種類和標(biāo)準、導(dǎo)游服務(wù)、旅行費用等信息也都在一定程度上影響著游客的選擇。圖5.3西藏布達拉宮和圖5.4云南香格里拉兩幅圖片顯示了西藏布達拉宮、云南香格里拉與眾不同的優(yōu)美景觀,吸引了眾多的游客前來觀光旅游,成為近年來國內(nèi)旅游的熱點。
2. let the Ss complete the forms paragraph by paragraph. Purpose here is to help Ss to get the habit of reading a passage as a whole, and pay attention to the organization of the text, as a result the Ss will fully understand the whole passage.3. ask Ss to retell the passage with the help of the key words in the form.Since the Ss in the class are in different levels, so I let them to fill in the blank to understand the meaning of the words and phrases better.

After that, Ss are encouraged to express their attitudes with the whole class. Collect their answers and don’t forget to praise them even if their answers may not be perfect.In this activity, discussion provides a vivid and active learning environment for Ss to communicate in English with newly learned language items. (Finally it comes to the homework.)StepⅥ: Homework (1min)1. Ss are required to read the text again after class and figure out the meaning of some complex sentences.2. Do the exercises on P19; This can help Ss to consolidate what they’ve learnt and make preparation for the next lessonPart4.
