4、主旨 哪一聯(lián)明確地點(diǎn)明全詩題旨?表達(dá)了作者的什么感情?試做分析 頸聯(lián)。 菊花開在秋天,所以這 “ 叢菊 ” 回應(yīng)了詩題中那個(gè) “ 秋 ” 字。 “ 他日 ” 可以指過去也可以指未來,在這里是指過去?!皡簿諆砷_”,指詩人于 765 年離開成都,原打算很快出峽,但這年留居云安,次年又留居夔州,見到叢菊開了兩次,還未出峽,故對(duì)菊掉淚。秋菊兩度盛開,使詩人再次灑下往日流過的眼淚?!伴_”字雙關(guān),一謂菊花開,又言淚眼隨之開。此時(shí)他仍然滯留在他鄉(xiāng),他始終沒有放棄回鄉(xiāng)的打算。孤舟可以系住,使其不能泛諸中流,但詩人的心是系不住的。他的心早已越過江河,越過關(guān)山,飛到了長(zhǎng)安。所以,一葉靠岸系繩的孤舟,始終都牽動(dòng)著詩人的故園之思。這一聯(lián)是全篇詩意所在。孤舟本來只能系住自己的行蹤,卻把詩人的思鄉(xiāng)之心也牢牢地系住了,故見舟傷心,引出故園之思,表現(xiàn)出思鄉(xiāng)之情的深沉濃烈和欲歸不得的無奈與凄傷,為文章的主旨句。
戰(zhàn)國陰陽五行家鄒衍認(rèn)為,歷史中的朝代更替是由于五德運(yùn)行產(chǎn)生的影響。按照鄒衍的學(xué)說,每個(gè)朝代必須與五德之一相連,因此,這個(gè)朝代就應(yīng)當(dāng)遵循這五德之一的要求來運(yùn)轉(zhuǎn)。董仲舒修改了這個(gè)理論,認(rèn)為朝代的更替不是依循五德運(yùn)行的順序,而是依循“三統(tǒng)”,即黑統(tǒng)、白統(tǒng)、赤統(tǒng)的順序。他在《三代改制質(zhì)文》中說:每個(gè)朝代都依循一統(tǒng),每統(tǒng)又各有其為政的系統(tǒng)。按董仲舒的說法,夏朝代表黑統(tǒng),商朝代表白統(tǒng);周朝則是赤統(tǒng)。夏、商、周三朝完成了這一歷史循環(huán)。之后,歷史又開始一次新的循環(huán),新的朝代又應(yīng)當(dāng)代表黑統(tǒng)。繼承周朝統(tǒng)治的既不是秦朝,也不是漢朝,而是孔子,他承受天命,創(chuàng)立了黑統(tǒng)。孔子所受天命,不是一種“法統(tǒng)”,而是一種“道統(tǒng)”。董仲舒說:“《春秋》大一統(tǒng)者,天地之常經(jīng),古今之通誼也。今師異道,人異論,百家殊方,指意不同,是以上亡以持一統(tǒng);法制數(shù)變,下不知所守。臣愚以為諸不在六藝之科孔子之術(shù)者,皆絕其道,勿使并進(jìn)。邪辟之說滅息,然后統(tǒng)紀(jì)可一而法度可明,民知所從矣?!?/p>

He was so hungry that he decided to beg for a meal at the next house.However, he lost his nerve when a lovely young woman opened the door. Instead of a meal he asked for a drink of water. She thought he looked hungry so she brought him a large glass of milk. He drank it slowly, and then asked, “How much do I owe you?” “You don’t owe me anything,” she replied, “Mother has taught me never to accept pay for a kindness.” “Then I thank you from the bottom of my heart.” With these words, Howard Kelly left that house.Years later the woman became badly ill and was finally sent to the hospital in a big city.

He looked at it and then wrote something on the side. The bill was sent to the woman’s room. She was afraid to open it because she was sure that it would take the rest of her life to pay for it off. Finally she looked, and the note on the side of the bill caught her attention. She read these words: “Paid in full with a glass of milk, Dr. Howard Kelly.” Tear of joy flooded her eyes.

Everybody wants to get wealth.In today’s material world,making money or becoming wealthy symbolizes a person’s success and capability. Many people just make every effort, pay any price to attain greater wealth. With money,they can buy nice, large apartments in nice neighborhood. With money they can own luxurious cars. Wealth seems to bring all happiness in life.But is wealth the only road to happiness? Not really. There are many things in the world, which are beyond the means of money, such as friendship, love, health and knowledge. People are so preoccupied with struggling for money that they have no time or would not take the time to form or maintain friendship. What happiness can they feel living as lonely miserable creatures without love or friends in the world even if they accumulate tremendous wealth?In my opinion, people can’t do anything without money, but money is not everything. What money will bring you depends on your personal belief and goal in life. If you are kind enough to help others, especially the poor, money is a good thing to you. With it, you can do much more for the benefit of people and your country, and it will add to your own happiness. If you want money just for your own needs, you’ll never be satisfied or happy. In a word,you should have money spent for more people. Only then can money be the source of your happiness.Step 8 Homework4 students in a group, one acts Roderick, one Oliver, one servant and the fourth one acts Henry Adams, then listen to the tape, pay more attention to the difference between American English and British English in pronunciation, stress, tone.

這幾段內(nèi)容傳達(dá)出的是“要敬畏生命,尊重生命;更要敬畏大自然,尊重大自然,愛護(hù)大自然”的主旨內(nèi)涵,因此讓學(xué)生通過自由朗讀的方式,再次體會(huì)馮至對(duì)這個(gè)消逝了的山村的細(xì)致的美好的描繪,感悟馮至傳達(dá)出的對(duì)生命,對(duì)自然的理解和思考。5.最后一個(gè)自然段的解讀依然是交給學(xué)生,先齊讀課文,再讓學(xué)生自主分享自己的體會(huì)或疑惑。但在這一環(huán)節(jié)我也設(shè)計(jì)了兩個(gè)我認(rèn)為必須解答的兩個(gè)問題,一是怎么理解“在風(fēng)雨如晦的時(shí)刻”;二是“意味不盡的關(guān)聯(lián)”是指什么。我認(rèn)為這兩個(gè)問題一個(gè)涉及到寫作背景,一個(gè)涉及到對(duì)全文主旨的一個(gè)整體把握,能夠進(jìn)一步幫助學(xué)生理解散文的深刻內(nèi)涵和主旨,讓學(xué)生有意識(shí)的在閱讀散文過程中通過背景知識(shí)進(jìn)行理解。既尊重學(xué)生的個(gè)性化解讀,又能夠讓學(xué)生有意義學(xué)習(xí),完成預(yù)設(shè)的教學(xué)目標(biāo)。如果學(xué)生沒有提到這兩處,那我就需要做出補(bǔ)充。
(2) 中國文人的悲秋情結(jié)。3.《荷塘月色》中,作者為什么要離開家來到荷塘散步?4. 思考:作者的心里為何“頗不寧靜?”(教師補(bǔ)充:寫作背景)5. 出門散步后,作者的心情發(fā)生變化了嗎? 有怎樣的變化?6.思考討論:為什么作者說“我”與“地壇”間有著宿命般的緣分,二者有何相似之處?(閱讀1-5段)7.思考:作者從他同病相憐的“朋友“身上理解了怎樣的”意圖“?三、課堂總結(jié)李白說:“天地者,萬物之逆旅也。”人生,如同一場(chǎng)旅行,在人生的旅途中,時(shí)而高山,時(shí)而峽谷,時(shí)而坦途,時(shí)而歧路。我們或放歌,或悲哭,然而,大自然始終以其不變的姿勢(shì)深情地看著我們,而我們,也應(yīng)該學(xué)會(huì)在與自然的深情對(duì)望中,找到生命的契合。正如敬亭山之于李白,故都的秋之于郁達(dá)夫,荷塘月色之于朱自清,地壇之于史鐵生,他們從中或得到心靈的慰藉、精神的寄托,或得到生存的智慧與勇氣,最終完成精神的超脫。
二、探究新知一、點(diǎn)到直線的距離、兩條平行直線之間的距離1.點(diǎn)到直線的距離已知直線l的單位方向向量為μ,A是直線l上的定點(diǎn),P是直線l外一點(diǎn).設(shè)(AP) ?=a,則向量(AP) ?在直線l上的投影向量(AQ) ?=(a·μ)μ.點(diǎn)P到直線l的距離為PQ=√(a^2 "-(" a"·" μ")" ^2 ).2.兩條平行直線之間的距離求兩條平行直線l,m之間的距離,可在其中一條直線l上任取一點(diǎn)P,則兩條平行直線間的距離就等于點(diǎn)P到直線m的距離.點(diǎn)睛:點(diǎn)到直線的距離,即點(diǎn)到直線的垂線段的長(zhǎng)度,由于直線與直線外一點(diǎn)確定一個(gè)平面,所以空間點(diǎn)到直線的距離問題可轉(zhuǎn)化為空間某一個(gè)平面內(nèi)點(diǎn)到直線的距離問題.1.已知正方體ABCD-A1B1C1D1的棱長(zhǎng)為2,E,F分別是C1C,D1A1的中點(diǎn),則點(diǎn)A到直線EF的距離為 . 答案: √174/6解析:如圖,以點(diǎn)D為原點(diǎn),DA,DC,DD1所在直線分別為x軸、y軸、z軸建立空間直角坐標(biāo)系,則A(2,0,0),E(0,2,1),F(1,0,2),(EF) ?=(1,-2,1),
