    1.國(guó)家石油價(jià)格上漲,導(dǎo)致依賴于國(guó)際石油而建立起來的日本重化工業(yè)的制造成本提高,產(chǎn)品價(jià)格相應(yīng)提高,削弱了日本重化工產(chǎn)品在國(guó)際市場(chǎng)上的競(jìng)爭(zhēng)力。2.日元 的大幅度升值,意味著日本產(chǎn)品在國(guó)際市場(chǎng)上的價(jià)格大幅度提高。例如,同樣的日本產(chǎn)品,如果原來在國(guó)際市場(chǎng)上賣1美元,日元升值1倍后其在國(guó)際市場(chǎng)上的售價(jià)就達(dá)2美元。所以,以國(guó)際市場(chǎng)為依托的日本傳統(tǒng)產(chǎn)業(yè)只好紛紛向海外轉(zhuǎn)移。3.自身市場(chǎng)滿足不了發(fā)展需求,國(guó)際市場(chǎng)上亞洲發(fā)展中國(guó)家和地區(qū)的同類產(chǎn)品具有明顯的價(jià)格優(yōu)勢(shì)。所以,日本企業(yè)在其國(guó)內(nèi)發(fā)展的空間很小。4.勞動(dòng)力價(jià)格高反映為產(chǎn)品的價(jià)格高,而勞動(dòng)力數(shù)量又滿足 不了企業(yè)進(jìn)一步擴(kuò)展對(duì)勞動(dòng)力的需求。所以,日本從事傳統(tǒng)產(chǎn)業(yè)的國(guó)內(nèi)企業(yè)生產(chǎn)受勞動(dòng)力價(jià)格和數(shù)量的雙重制約。5.促進(jìn)日本企業(yè)生產(chǎn)的區(qū)位選擇向國(guó)土的南、北部和海外擴(kuò)展。6.“技術(shù)立國(guó)”的政策明顯對(duì)傳統(tǒng)產(chǎn)業(yè)在國(guó)內(nèi)生產(chǎn)不利,即企業(yè)生產(chǎn)要么向知識(shí)技術(shù)密集型轉(zhuǎn)換(這需要大量的投資),要么轉(zhuǎn)向海外。

    二、課堂教學(xué):1、學(xué)生簡(jiǎn)介背景:教師掌握:漢武帝開始對(duì)匈奴進(jìn)行長(zhǎng)期的討伐戰(zhàn)爭(zhēng),其中取得了三次具有決定意義的勝利,時(shí)間為公元前127年、前121年、前119年。匈奴的威勢(shì)大大削弱之后,表示愿意與漢講和,但雙方矛盾還是根深蒂固。所以,到公元前100年,蘇武出使匈奴時(shí),卻被扣留,并迫使他投降?!短K武傳》集中敘寫了蘇武出使匈奴被扣留期間的事跡,熱烈頌揚(yáng)了他在敵人面前富貴不能淫,貧賤不能移,威武不能屈,饑寒壓不倒,私情無所動(dòng)的浩然正氣,充分肯定了他堅(jiān)毅忠貞,大義凜然,視死如歸的民族氣節(jié)。2、作者介紹:班固(32——92年),字孟堅(jiān),扶風(fēng)安陵(今陜西咸陽(yáng)市東)人。東漢著名的史學(xué)家。《后漢書·班固傳》稱他“年九歲,能屬文,誦詩(shī)賦。及長(zhǎng),遂博貫載籍,九流百家之言,無不窮究。所學(xué)無常師,不為章句,舉大義而已”。其父班彪曾續(xù)司馬遷《史記》作《史記后傳》,未成而故。

    人教版高中語(yǔ)文必修3《寡人之于國(guó)也》說課稿2篇

    (明確:“寡人之于國(guó)也,盡心焉耳矣”,但“寡人之民不加多,何也?”)②他認(rèn)為自己對(duì)國(guó)家政務(wù)盡心盡力了,他有哪些具體做法?(明確:移民移粟)③第2—4節(jié)中孟子是怎樣說明梁惠王移民移粟的措施與“鄰國(guó)之政”并無本質(zhì)區(qū)別的?(明確:孟子不直接回答“民不加多”的問題,而是用梁惠王熟悉的“戰(zhàn)”設(shè)喻——設(shè)圈套,誘使對(duì)方在不知不覺中說出“不可,直不百步耳,是亦走也。”)④孟子認(rèn)為怎樣才能做到“王道之始”?要想“王道之成”還需采取哪些措施?(明確:“不違農(nóng)時(shí),谷不可勝食也。數(shù)罟不入氵夸池,魚鱉不可勝食也。斧斤以時(shí)入山林,材木不可勝用也。谷與魚鱉不可勝食,材木不可勝用五畝之宅,樹之以桑,五十者可以衣帛矣。雞豚狗彘之畜,無失其時(shí),七十者可以食肉矣。百畝之田,勿奪其時(shí),數(shù)口之家,可以無饑矣。謹(jǐn)庫(kù)序之教,申之以孝涕之義,頒白者不負(fù)戴于道路矣。)這一小步的目的是想讓學(xué)生通過這些問題的解答,可以進(jìn)一步理清思路,掌握文的大概內(nèi)容。

    3、重要語(yǔ)句的理解“可是一個(gè)人并不是生來要給打敗的,你盡可把它消滅掉,可就是打不敗他?!苯馕觯哼@是老人第一次回合之后的內(nèi)心獨(dú)白,也是此小說的核心精神,充分體現(xiàn)了老人桑地亞哥的生命理念。整句話可以分為兩部分來理解,前句告訴我們,人生活在自然與社會(huì)當(dāng)中,必不可少要面臨一些坎坷、磨難,這些磨難、坎坷完全可以造成軀體的消滅、消亡,這是人生命的脆弱性。后句,面對(duì)挫折,只要保持一種樂觀的精神,擁有一顆堅(jiān)強(qiáng)的心靈,那么,人類執(zhí)著奮斗的精神將永不磨滅。4、象征主義題目是《老人與?!?,而表明上,小說是寫一位老人及其在海上的經(jīng)歷,但實(shí)際上,老人的形象極具概括性,他已經(jīng)超越了一個(gè)人的存在,而成為了人生的一種象征。老人桑地亞哥就是“硬漢子”的代表,大海則是生命旅途的象征,鯊魚則是我們行走中的“強(qiáng)物”,厄運(yùn)的象征。人的一生不可能一帆風(fēng)順,不經(jīng)歷風(fēng)雨,怎能見彩虹,走在人生路途中,不可避免我們都要遇到挫折,被厄運(yùn)所阻撓,只有經(jīng)歷與“鯊魚”的較量,才能成為強(qiáng)者,唱出最美的歌。
