1.國家石油價格上漲,導致依賴于國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)品價格相應提高,削弱了日本重化工產(chǎn)品在國際市場上的競爭力。2.日元 的大幅度升值,意味著日本產(chǎn)品在國際市場上的價格大幅度提高。例如,同樣的日本產(chǎn)品,如果原來在國際市場上賣1美元,日元升值1倍后其在國際市場上的售價就達2美元。所以,以國際市場為依托的日本傳統(tǒng)產(chǎn)業(yè)只好紛紛向海外轉移。3.自身市場滿足不了發(fā)展需求,國際市場上亞洲發(fā)展中國家和地區(qū)的同類產(chǎn)品具有明顯的價格優(yōu)勢。所以,日本企業(yè)在其國內(nèi)發(fā)展的空間很小。4.勞動力價格高反映為產(chǎn)品的價格高,而勞動力數(shù)量又滿足 不了企業(yè)進一步擴展對勞動力的需求。所以,日本從事傳統(tǒng)產(chǎn)業(yè)的國內(nèi)企業(yè)生產(chǎn)受勞動力價格和數(shù)量的雙重制約。5.促進日本企業(yè)生產(chǎn)的區(qū)位選擇向國土的南、北部和海外擴展。6.“技術立國”的政策明顯對傳統(tǒng)產(chǎn)業(yè)在國內(nèi)生產(chǎn)不利,即企業(yè)生產(chǎn)要么向知識技術密集型轉換(這需要大量的投資),要么轉向海外。

知識和技能 1、 了解區(qū)域工業(yè)化和城市化之間的關系,以及它們對區(qū)域社會經(jīng)濟發(fā)展所起的作用 。2、分析導致珠江三角洲工業(yè)化和城市化快速推進的諸多思想束縛,并通過比較,認識到對外開放政策是其中的關鍵因素。3、 比較珠江三角 洲的 區(qū)工業(yè)化進程的兩個主要階段,歸納出不同時期的主要發(fā)展特點,并能夠結合具體案例分析工業(yè)化進程對城市化的巨大推動。 4、分析珠江三角洲地區(qū)工業(yè)化和城市化進程中的問題,并嘗試評價目前的一些調(diào)整措施和發(fā)展方向。5、通過分析我國珠江三角 洲地區(qū)工 業(yè)化、城市化的發(fā)展階段、問題與對策,了解區(qū)域工業(yè)化和城市化的推進動力和發(fā)展規(guī)律。過程與方法 利用扮演不同的社會角色來談對珠江三角洲地區(qū)未來經(jīng)濟和城鎮(zhèn)發(fā)展的設想和建議,反饋學生知識、能力、價值觀發(fā)展情況和效果, 培養(yǎng)學生對所學所得的運用能力,并為學生的創(chuàng)新精神的發(fā) 展營造有利氛圍。情感、態(tài)度與價值觀1、通過鼓勵學生主動獲 取資料的做法,關注學生實踐能力、綜合思維能力及終身學習能力的訓練。
【新知識點】認識扇形統(tǒng)計圖統(tǒng)計填寫扇形統(tǒng)計圖根據(jù)扇形統(tǒng)計圖所提供的數(shù)據(jù)回答問題【單元教學目標】1,認識扇形統(tǒng)計圖,了解扇形統(tǒng)計圖的特點.2,能夠看懂并會填扇形統(tǒng)計圖.3,會根據(jù)扇形統(tǒng)計圖所提供的數(shù)據(jù)回答一些簡單的問題.4,進一步了解統(tǒng)計在實際生活中的地位和作用.5,通過對相關素材的整理和分析,使學生受到一定的思想教育.【單元教學重難點】重點:學生掌握扇形統(tǒng)計圖的特點和作用.難點:在學習中體會各種統(tǒng)計圖的不同特點.【教學建議】學生已經(jīng)系統(tǒng)地學習過有關條形統(tǒng)計圖和折線統(tǒng)計圖的知識,也初步認識了扇形,而且也學習了有關百分數(shù)的知識,所有這些都為學校繼續(xù)學習統(tǒng)計圖的最后一部分內(nèi)容——扇形統(tǒng)計圖打下了良好的基礎.【課時安排】
分別算出2008年比2007年各季度增產(chǎn)的百分數(shù)和合計數(shù),再制成統(tǒng)計表.分析:根據(jù)題目要求,要算出各季度增產(chǎn)的百分數(shù),我們只要根據(jù)2008年與2007年各個季度的原始數(shù)據(jù),運用“求一個數(shù)是另一個數(shù)的百分之幾”的方法就可以算出.算出了各個季度增產(chǎn)的百分數(shù),根據(jù)題意制統(tǒng)計表時,既要按照季度分類,又要反映出年份的類別,所以在確定表頭時可分為3部分:年份、臺數(shù)、季度,年份又分為2007年產(chǎn)量、2008年產(chǎn)量、2008年比2007年增產(chǎn)的百分數(shù).2、田力化肥廠今年第一季度生產(chǎn)情況如下:元月份計劃生產(chǎn)1500噸,實際生產(chǎn)1620噸;二月計劃生產(chǎn)1600噸,實際生產(chǎn)1680噸;三月份計劃生產(chǎn)1640噸,實際生產(chǎn)1720噸,根據(jù)上面的數(shù)據(jù),算出各月完成計劃的百分數(shù),并制成統(tǒng)計表.(1)制作含有百分數(shù)的統(tǒng)計表時,百分數(shù)這一欄一定要寫清楚是誰占誰的百分之幾,并按“求一個數(shù)是另一個數(shù)的百分之幾”的解題方法正確算出對應百分數(shù)”
《樹之歌》是統(tǒng)編版二年級上冊第二單元的一篇韻文識字教學課文。兒童熟悉的拍手游戲為活動形式,串起了八種動物的生活場景。兒歌共十個小節(jié),開頭與結尾三個小節(jié)相互呼應,中間的六個小節(jié)分別介紹了羽毛艷麗的孔雀和錦雞,展翅翱翔的雄鷹,成群的大雁,叢林中的猛虎,啼叫的黃鸝和百靈鳥,憨態(tài)可掬的大熊貓。兒歌主要運用擬人手法,使動物形象更加親切可愛,富有童趣。在教學時,可側重培養(yǎng)學生的誦讀能力,在讀中領悟兒歌大意,體會兒歌蘊含的思想感情,使學生受到情感的熏陶。運用多種形象直觀的教學手段,創(chuàng)設豐富多彩的教學情景,采用多種方法科學地識記繩生字,提高學生的認字效率和識字興趣。 1.認識“世、界”等14個生字,會寫“歌、寫”等10個生字,了解“隹”“鳥”偏旁表義的特點。掌握本課的相關詞語。2.正確、流利地朗讀兒歌,讀出節(jié)奏感并背誦。3.感受動物生活的自由、快樂,培養(yǎng)學生保護動物的意識。 1.教學重點:學會本課生字,了解“隹”“鳥”偏旁表義的特點。正確、流利地朗讀兒歌,讀出節(jié)奏感并背誦。2.教學難點:了解“隹、鳥”等偏旁表義的特點。感受動物生活的自由、快樂,培養(yǎng)學生保護動物的意識。 2課時

A.20x-55≥350 B.20x+55≥350C.20x-55≤350 D.20x+55≤350解析:此題中的不等關系:現(xiàn)在已存有55元,計劃從現(xiàn)在起以后每個月節(jié)省20元.若此學生平板電腦至少需要350元.列出不等式20x+55≥350.故選B.方法總結:用不等式表示數(shù)量關系時,要找準題中表示不等關系的兩個量,并用代數(shù)式表示;正確理解題中的關鍵詞,如負數(shù)、非負數(shù)、正數(shù)、大于、不大于、小于、不小于、不足、不超過、至少、至多等的含義.三、板書設計1.不等式的概念2.列不等式(1)找準題目中不等關系的兩個量,并且用代數(shù)式表示;(2)正確理解題目中的關鍵詞語的確切含義;(3)用與題意符合的不等號將表示不等關系的兩個量的代數(shù)式連接起來;(4)要正確理解常見不等式基本語言的含義.本節(jié)課通過實際問題引入不等式,并用不等式表示數(shù)量關系.要注意常用的關鍵詞的含義:負數(shù)、非負數(shù)、正數(shù)、大于、不大于、小于、不小于、不足、不超過,這些關鍵詞中如果含有“不”“非”等文字,一般應包括“=”,這也是學生容易出錯的地方.

活動目標: 1、讓幼兒在猜猜、想想、看看、數(shù)數(shù)的游戲中復習5以內(nèi)的數(shù)數(shù),序數(shù)和排序。 2、發(fā)展幼兒的觀察力,提高幼兒對計算活動的興趣。 3、趣味識字:橘子、葡萄、梨子、蘋果、西瓜、桃子、草莓香蕉等?;顒訙蕚洌? 1、貼絨水果娃娃5個(背后貼有水果),顏色不同的卡車5輛,二進制游戲圖片一張,各種水果拼圖20張。 2、每組1----5數(shù)字卡片若干。識字卡:橘子、葡萄、梨子、蘋果、西瓜、桃子、草莓、香蕉等。 活動過程: 一、開始部分 出示水果娃娃,引起興趣?!敖裉?,老師請來了水果娃娃,我們來看看都有些什么水果?”(橘子、葡萄、梨子、蘋果、西瓜、桃子、草莓、香蕉)我們來數(shù)數(shù),一共有幾種水果娃娃呢? 二、基本部分 1、猜數(shù)和排序 (1)猜數(shù) 水果娃娃要和小朋友玩?zhèn)€猜數(shù)的游戲,每個水果娃娃背后都藏有一個數(shù)字,你們想知道是數(shù)字幾嗎? a、梨子娃娃說;“我比2多1”,誰知道這個數(shù)字是幾呢? B、葡萄娃娃說“我比5少1” C、橘子娃娃說“我是1-----5數(shù)字中最小的那個數(shù),是數(shù)字幾呢? D、你們看看1----5數(shù)字中還剩下哪兩個數(shù)呢?那西瓜娃娃和蘋果娃娃誰是2誰是5呢?西瓜娃娃說:“我的數(shù)字比蘋果娃娃大,誰能告訴大家是幾?那蘋果娃娃是數(shù) 字幾? (2)鞏固 現(xiàn)在老師看看你們記住了沒有,加以驗證。師指認每個水果娃娃,讓幼兒說出背后的數(shù)字。 (3)猜猜少了哪個數(shù)? 現(xiàn)在老師任意拿走一樣水果,問少了幾,是什么水果,重復指認水果和數(shù)字。
活動目標:通過實踐活動,學會用自己的方法分類統(tǒng)計生活中物品的數(shù)量,從中體驗數(shù)學的有趣及重要?;顒訙蕚洌航處熓孪冗x擇好實踐的場地(幼兒園內(nèi)),并親自實踐一遍做好記錄,心中有數(shù);紙、筆。活動過程:(一)復習鞏固:1、你能從1數(shù)到幾?數(shù)數(shù)看。2、更快的數(shù)數(shù)方法:5個5個地數(shù),10個10個地數(shù)。3、100以內(nèi)的隨便一個數(shù)你會寫嗎?試試看(請幾個幼兒到黑板上聽寫)。(注:此環(huán)節(jié)的目的在于教師了解幼兒在實踐活動中必備的一些相關知識掌握如何,以便在活動中更好地把握。)(二)聯(lián) 系生活:1、在生活中,你碰到什么東西要用數(shù)來數(shù)?舉例子。2、在幼兒園里也藏了許多數(shù),請小朋友們說說。3、用什么方法統(tǒng)計方便?(每5個或10個記錄一次,然后5個5個或10個10個地數(shù);列表統(tǒng)計等)
