材料五航路開辟后，東方香料輸入歐洲的總量較中古之時猛增30倍，而胡椒、丁香等在印度購入和在英國賣出的差價亦高達10至29倍，其他貨物的獲利同樣驚人。這一時期，新的商品不斷涌現(xiàn)，特別值得注意的是美洲的特產(chǎn)——玉米、馬鈴薯、煙草、可可等——被傳播到歐亞大陸。這時，世界性的對外貿(mào)易主要通過大西洋，地中海與意大利皆告衰落，而沿大洋的英、荷等漸居中心。到17世紀時，英國的倫敦與荷蘭的阿姆斯特丹成為世界貿(mào)易中心。問題4：材料五表明，新航路開辟后對世界貿(mào)易產(chǎn)生了哪些重大影響？答案4：結(jié)束了世界相對孤立狀態(tài)；各地文明開始會合交流，日益連成一個整體；歐洲商人直接同世界各地建立商業(yè)聯(lián)系；促進不同國家和貿(mào)易的發(fā)展，促進世界市場雛形開始出現(xiàn)。

【教學參考】對“新政”作用的評價史學界對“新政”作用的評價是仁者見仁、智者見智，但基本上有三種觀點，即“功大于過論”、“過大于功論”和“功過參半論”。持“功大于過論”者認為“新政”在美國歷史上基本上是一種進步現(xiàn)象，首先，“新政”挽救了危機，使美國人民擺脫了危機的困苦局面；其次，在缺少足夠的宏觀經(jīng)濟政策知識的時代，羅斯福所做的努力確實是開創(chuàng)性的；再次，羅斯?！靶抡遍_啟了美國以后歷屆政府實施國家干預(yù)政策的大門，成為緩解自由主義經(jīng)濟制度之弊病的一劑良方，并在實質(zhì)上加強了美國聯(lián)邦政府的權(quán)威；最后，在30年代資本主義世界經(jīng)濟危機的背景下，同日本、德國為轉(zhuǎn)嫁危機而發(fā)動戰(zhàn)爭的策略相比，“新政”無疑代表了一種進步、民主的解救危機方式。持“過大于功論”者認為“新政”未能使美國走出蕭條、步入繁榮。

人教版高中語文必修5《說“木葉”》教案
【教學目標】Ⅰ、學習理解詩歌語言的暗示性特質(zhì)。Ⅱ、根據(jù)詩歌語言的特質(zhì)，進行遷移，領(lǐng)略詩歌的精妙之處，給同學如何鑒賞詩歌提供實感。㈠、導入：各位同學，有個成語叫"一字千金"。對我而言，第一次領(lǐng)略到一個字的分量，是在小學三年級的時候，一次作文評析課上。當時我對自己的文章充滿了期待，希望能得到老師的贊賞。記得老師進來后的第一句話是"有一篇文章，我就沖它用了一個字，我給它打95分。打這樣的高分，對我來說，是極為難得的。"同學都充滿了好奇，老師接著說"這個字就是一個'悟'字。我們的同學都說我學到了，我明白了，我懂得了一個道理，而這位同學卻用了一個'悟'字，難能可貴。"這篇文章不是我的，在羨慕的同時，一個字在文章中的分量就深深的刻在了我的心上。文學作品中，一個字精妙與否，足以決定作品是流光溢彩，還是黯然失色。尤其是我們的古典詩詞，用簡短的幾個字，造就的卻是豐富的情感與博大的意境。讀后滿口余香，卻是妙處難與君說。這跟詩歌的語言是密不可分的。今天，我們就通過《說"木葉"》一文，對中國古典詩詞語言特質(zhì)作一番探幽。

竇娥的三樁誓愿明明是幻想，卻偏偏寫成現(xiàn)實，明明是不合理的偏偏寫成合理的，這說明了什么？明確：這說明在當時的歷史條件下，除了乞求天地鬼神申訴冤屈以外，沒有別的辦法，作者采用這種浪漫主義的表現(xiàn)手法，一是表明社會的腐敗黑暗，二是刻畫竇娥強烈的反抗精神，三是表達人民要懲治邪惡的愿望?！吧贰本褪墙Y(jié)尾的曲牌，為什么關(guān)漢卿要把“煞”分成［二煞］［一煞］[煞尾]三個曲牌呢？明確：說明蓄積在竇娥胸中的怒火再也無法控制，猶如地下巖漿，沖向決口。也說明劇作家意猶未盡，他要把竇娥的無辜受害，要把人們對竇娥的同情，要把人們對統(tǒng)治者的憤恨表現(xiàn)得痛痛快快，淋漓盡致。于是在結(jié)尾處一波三折，把高潮推向頂峰?！陡]娥冤》中有兩句唱詞，兩個牌文本不同，試分析其優(yōu)劣?！豆琶译s劇》本：地也，你不分好歹難為地；天也，我今日負屈銜冤哀告天。
