(引入新課)
(提問)在晴天的一天中,早晨、中午和傍晚三個時間相比,哪個時間我們感覺到太陽光照射得最利害?為什么?
(太陽光線照射地面的角度越大,地面獲得的太陽光熱就越多)。根據(jù)各地獲得太陽光熱的多少,人們劃分了五帶。

5.我國大部分位于哪個溫度帶?還有一小部分位于哪個帶?
6.說出各帶的突出特點?
討論后學生分組回答,老師補充相關內容。
(活動2)分組討論(以北京為例):
1.北京1年中哪個月氣溫最高?哪個月氣溫最低?一年四季每個季節(jié)各幾個月?
(氣溫最高7月,開始放暑假;氣溫最低1月,開始放寒假;每個季節(jié)3個月)
2.你知道24節(jié)氣嗎?7月應該是哪兩個節(jié)氣?1月是哪兩個節(jié)氣嗎?
(7月小暑和大暑,最熱;1月是小寒和大寒,最冷)
3.北半球各季節(jié)各是哪三個月?
(春季:12、1、2月;夏季:3、4、5月;秋季:6、7、8月;冬季:12、1、2月。這種四季是以天文四季和氣候四季相結合來劃分的。)

《出師表》教學設計第四課時
教案課件是老師不可缺少的課件,大家應該開始寫教案課件了。只有寫好教案課件計劃,才能夠使以后的工作更有目標性!你們知道哪些教案課件的范文呢?下面是小編為大家整理的“《出師表》教學設計第四課時”,希望對您的工作和生活有所幫助。
《出師表》教學設計第四課時
第四課時一、檢查背誦情況。二、講讀8、9段。1學生朗讀這兩段課文,并指名講述大意。2教師重點點撥:以咨諏善道,察納雅言,深追先帝遺詔:以,表示目的,譯為“來”。3分析結構層次。板書:三、歸納中心思想。明確:本文以懇切的言辭勸告劉禪認識必須親賢遠佞,才能修明政治,從而完成“興復漢室,還于舊都”的大業(yè)。四、歸納寫作特點。1以議論為主,兼用抒情和記敘。第一部分寓情于議,第二部分寓情于事,最后一部分談各方面的責任,也表達了完成先帝遺愿的決心。具體說來有三方面特點。(1)反復提及劉備的遺言、“遺德”、“遺詔”,在文章的重要關節(jié)無不提及“先帝”,處處從先帝說起,時時提先帝遺訓。全文僅600多字,竟先后13處提及先帝。其作用是勉勵劉禪“光先帝之遺德”,“深追先帝遺詔”,以完成先帝未竟大業(yè)。(2)常從自身的經歷、體驗和感情談起,以自己忘身憂國的一腔忠貞來作為對后主的激勵。(3)處處從“陛下”的帝業(yè)、威望、聲譽著想。由于上面三個特點,使本文達到了“忠言不逆耳,辭切見情深”的藝術效果,使劉禪再昏庸糊涂也當欣然聽取,甘愿采納。2語言樸素無華,字斟句酌。形成這一特點的原因是:(1)與受表者的對象有關。劉禪本人的年齡識見,文化素養(yǎng),決定了該文語詞樸實,叮嚀周備。(2)寫表與受表者之間特殊關系,決定了該表委婉、懇切、字勘句酌的特點。諸葛亮是后主的臣,但又是后主的長輩,劉備臨終時云“以父事之”。陸游云:“凜然出師表,一字不可刪?!蔽濉⒉贾米鳂I(yè)。
Unit6Howlonghaveyoubeencollectingshells?第四課時教案
一.疑難解析
I.如何表示“從過去開始一直持續(xù)到現(xiàn)在,有可能還要持續(xù)下去的動作”。如:到現(xiàn)在為止她滑冰已經有四個小時了。又如:我從十歲起就一直在集郵。我們采用如下的方法來表示“從過去開始一直持續(xù)到現(xiàn)在,還要持續(xù)下去的動作”:
主語+have/hasbeen+現(xiàn)在分詞,如:
1.Shehasbeenskatingforfourhours.到現(xiàn)在為止她滑冰已經有四個小時了。
2.IhavebeencollectingstampssinceIwastenyearsold.我從十歲起就一直在集郵。
在這兩個句子中,have和has是助動詞,因此把助動詞提前,就構成了一般疑問句,在have或has后面加not,就構成了否定形式,havenot和hasnot可以分別縮寫成haven’t和hasn’t。如:
1.Haveyoubeendoingyourhomeworksincethismorning?
從今天早晨起你就一直在寫作業(yè)吧?
(表明寫作業(yè)這個動作從今天早晨就開始了,一直持續(xù)到現(xiàn)在,還要持續(xù)下去。)
2.Ihaven’tbeenseeingfilmsforalongtime.我有很長時間沒有看電影了。
(表明沒有看電影這個動作從過去一直持續(xù)到現(xiàn)在,還要繼續(xù)持續(xù)下去。)
II.區(qū)分“主語+have/hasbeen+現(xiàn)在分詞”和“主語+動詞過去式”這兩個句式的不同點及熟練掌握這兩個句式的用法。
1.“主語+have/hasbeen+現(xiàn)在分詞”表示動作從過去開始一直持續(xù)到現(xiàn)在,并且還要繼續(xù)持續(xù)下去。如:
Heisapianist.Hehasbeenplayingthepianoforabouttwentyyears.
他是一個鋼琴家。他彈鋼琴大約有二十年了。
彈鋼琴這個動作從二十年前就開始了,一直持續(xù)到現(xiàn)在,由于他是個鋼琴家,那么彈鋼琴這個動作還要繼續(xù)持續(xù)下去。這里強調持續(xù),而不是二十年間他一刻不停地在彈琴。又如:
Ihavebeencollectingsnowglobesforsevenyears.
我收集里面有雪花的玻璃裝飾品有七年了。
我有這個愛好,七年間我一直在收集這樣的裝飾品,但是不等于七年間我別的什么也沒干。
2.“主語+動詞的過去式”表式過去某個時間已經發(fā)生了動作,有比較明確的表示過去的時間狀語。如:
Ididmyhomeworklastnight.我昨天晚上做的作業(yè)。
表明“做作業(yè)”這個動作發(fā)生在昨天晚上,動作沒有持續(xù)性。
二.寫作指導
大家在學完這個單元以后要完成兩個寫作任務,即寫一個招聘廣告和一封應聘信。招聘廣告可以模仿49頁上的第3題來寫,應聘信可參考第48頁上的3a來寫。
下面請看示例:
學校歌詠隊要參加一個歌詠比賽,故而要招聘新成員,請你幫歌詠隊寫一個招聘廣告。
