(2)問(wèn)銷售該商品第幾天時(shí),當(dāng)天銷售利潤(rùn)最大,最大利潤(rùn)是多少?解析:(1)分1≤x<50和50≤x≤90兩種情況進(jìn)行討論,利用利潤(rùn)=每件的利潤(rùn)×銷售的件數(shù),即可求得函數(shù)的解析式;(2)利用(1)得到的兩個(gè)解析式,結(jié)合二次函數(shù)與一次函數(shù)的性質(zhì)分別求得最值,然后兩種情況下取最大的即可.解:(1)當(dāng)1≤x<50時(shí),y=(200-2x)(x+40-30)=-2x2+180x+2000;當(dāng)50≤x≤90時(shí),y=(200-2x)(90-30)=-120x+12000.綜上所述,y=-2x2+180x+2000(1≤x<50),-120x+12000(50≤x≤90);(2)當(dāng)1≤x<50時(shí),y=-2x2+180x+2000,二次函數(shù)開(kāi)口向下,對(duì)稱軸為x=45,當(dāng)x=45時(shí),y最大=-2×452+180×45+2000=6050;當(dāng)50≤x≤90時(shí),y=-120x+12000,y隨x的增大而減小,當(dāng)x=50時(shí),y最大=6000.綜上所述,銷售該商品第45天時(shí),當(dāng)天銷售利潤(rùn)最大,最大利潤(rùn)是6050元.方法總結(jié):本題考查了二次函數(shù)的應(yīng)用,讀懂表格信息、理解利潤(rùn)的計(jì)算方法,即利潤(rùn)=每件的利潤(rùn)×銷售的件數(shù),是解決問(wèn)題的關(guān)鍵.
如圖所示,要用長(zhǎng)20m的鐵欄桿,圍成一個(gè)一面靠墻的長(zhǎng)方形花圃,怎么圍才能使圍成的花圃的面積最大?如果花圃垂直于墻的一邊長(zhǎng)為xm,花圃的面積為ym2,那么y=x(20-2x).試問(wèn):x為何值時(shí),才能使y的值最大?二、合作探究探究點(diǎn)一:二次函數(shù)y=ax2+bx+c的最值已知二次函數(shù)y=ax2+4x+a-1的最小值為2,則a的值為()A.3 B.-1 C.4 D.4或-1解析:∵二次函數(shù)y=ax2+4x+a-1有最小值2,∴a>0,y最小值=4ac-b24a=4a(a-1)-424a=2,整理,得a2-3a-4=0,解得a=-1或4.∵a>0,∴a=4.故選C.方法總結(jié):求二次函數(shù)的最大(小)值有三種方法,第一種是由圖象直接得出,第二種是配方法,第三種是公式法.變式訓(xùn)練:見(jiàn)《學(xué)練優(yōu)》本課時(shí)練習(xí)“課堂達(dá)標(biāo)訓(xùn)練” 第1題探究點(diǎn)二:利用二次函數(shù)求圖形面積的最大值【類型一】 利用二次函數(shù)求矩形面積的最大值
解析:正多邊形的邊心距、半徑、邊長(zhǎng)的一半正好構(gòu)成直角三角形,根據(jù)勾股定理就可以求解.解:(1)設(shè)正三角形ABC的中心為O,BC切⊙O于點(diǎn)D,連接OB、OD,則OD⊥BC,BD=DC=a.則S圓環(huán)=π·OB2-π·OD2=πOB2-OD2=π·BD2=πa2;(2)只需測(cè)出弦BC(或AC,AB)的長(zhǎng);(3)結(jié)果一樣,即S圓環(huán)=πa2;(4)S圓環(huán)=πa2.方法總結(jié):正多邊形的計(jì)算,一般是過(guò)中心作邊的垂線,連接半徑,把內(nèi)切圓半徑、外接圓半徑、邊心距,中心角之間的計(jì)算轉(zhuǎn)化為解直角三角形.變式訓(xùn)練:見(jiàn)《學(xué)練優(yōu)》本課時(shí)練習(xí)“課后鞏固提升”第4題【類型四】 圓內(nèi)接正多邊形的實(shí)際運(yùn)用如圖①,有一個(gè)寶塔,它的地基邊緣是周長(zhǎng)為26m的正五邊形ABCDE(如圖②),點(diǎn)O為中心(下列各題結(jié)果精確到0.1m).(1)求地基的中心到邊緣的距離;(2)已知塔的墻體寬為1m,現(xiàn)要在塔的底層中心建一圓形底座的塑像,并且留出最窄處為1.6m的觀光通道,問(wèn)塑像底座的半徑最大是多少?
解析:(1)由切線的性質(zhì)得AB⊥BF,因?yàn)镃D⊥AB,所以CD∥BF,由平行線的性質(zhì)得∠ADC=∠F,由圓周角定理的推論得∠ABC=∠ADC,于是證得∠ABC=∠F;(2)連接BD.由直徑所對(duì)的圓周角是直角得∠ADB=90°,因?yàn)椤螦BF=90°,然后運(yùn)用解直角三角形解答.(1)證明:∵BF為⊙O的切線,∴AB⊥BF.∵CD⊥AB,∴∠ABF=∠AHD=90°,∴CD∥BF.∴∠ADC=∠F.又∵∠ABC=∠ADC,∴∠ABC=∠F;(2)解:連接BD,∵AB為⊙O的直徑,∴∠ADB=90°,∴∠A+∠ABD=90°.由(1)可知∠ABF=90°,∴∠ABD+∠DBF=90°,∴∠A=∠DBF.又∵∠A=∠C,∴∠C=∠DBF.在Rt△DBF中,sin∠DBF=sinC=35,DF=6,∴BF=10,∴BD=8.在Rt△ABD中,sinA=sinC=35,BD=8,∴AB=403.∴⊙O的半徑為203.方法總結(jié):運(yùn)用切線的性質(zhì)來(lái)進(jìn)行計(jì)算或論證,常通過(guò)作輔助線連接圓心和切點(diǎn),利用垂直構(gòu)造直角三角形解決有關(guān)問(wèn)題.

1.懸念法懸念法又稱關(guān)子。它是作者為了激發(fā)那種“緊張與期待的心理活動(dòng)”,在行文中有意采取的一種積極而有效的手段。這種手段包括“設(shè)懸”和“解懸”兩方面。所謂 “設(shè)懸”就是設(shè)置懸念,即在情節(jié)發(fā)生發(fā)展的關(guān)鍵時(shí)刻或人物命運(yùn)攸關(guān)的重要關(guān)頭,敘述戛然而止,轉(zhuǎn)敘他事。從而引起讀者強(qiáng)烈的尋根問(wèn)底的興趣。所謂“解懸” 也叫“釋?xiě)摇保褪侵冈谇楣?jié)發(fā)展的特定階段,通過(guò)矛盾的解決,揭示事情原委和人物命運(yùn)的結(jié)局,使讀者的期待心理得以滿足。如《驛路梨花》,當(dāng)人們正為露宿而發(fā)愁時(shí)出現(xiàn)了一間神秘的小屋,小屋的主人是誰(shuí)呢?猜想間,有人來(lái)了,但也不是屋子主人,那小屋子的主人是誰(shuí)呢?終于知道了小屋是解放軍蓋的,但為什么要蓋這間小屋呢?這樣“設(shè)懸——釋?xiě)摇獛С鲂聭夷睢?,環(huán)環(huán)相扣、層層遞進(jìn),使文章韻味無(wú)窮。
天上有明月,年年照相思。她夜夜沉醉在夢(mèng)中。夢(mèng)把空間縮短了,夢(mèng)把時(shí)間凝固了,夢(mèng)把世界凈化了。夢(mèng)中沒(méi)有污穢,沒(méi)有嘈雜,沒(méi)有邪惡;夢(mèng)中沒(méi)有分離,沒(méi)有創(chuàng)傷,沒(méi)有痛苦;夢(mèng)中只有柔和的月色,只有溫馨的愛(ài);夢(mèng)使她永遠(yuǎn)年輕,使她不原醒來(lái)?!?,那個(gè)世界,是為天下最真最善最美的心靈準(zhǔn)備的,藝術(shù)家懷著虔誠(chéng)的情感,用充滿魔力的琴弦,在人們的心中筑起了一座不朽的天堂,它像天地一樣長(zhǎng)久,日月一樣永恒!新月微微地閉著眼睛,她清清楚楚地看到了那座天堂,真真切切地觸到了那座天堂,冰凌砌成墻壁,白云鋪成房頂,霧靄織成紗幔,星星串成明燈;在那里,她的頭發(fā)像沐浴之后那樣清爽柔軟,隨風(fēng)飄拂,她的肌膚像披著月光那樣清涼潤(rùn)滑,她的那顆心啊,像浸潤(rùn)著蒙蒙細(xì)雨的花蕾,掛著晶瑩的露珠,自由地呼吸……她沉醉在那個(gè)一塵不染的美好的境界,如歌如詩(shī),如夢(mèng)如幻,如云如月,如水如煙……
3.作者為什么不直接描寫(xiě)人們看見(jiàn)東西呢?請(qǐng)同學(xué)們找出其中的細(xì)節(jié)描寫(xiě),并說(shuō)明有什么表達(dá)效果。答:側(cè)面烘托,正是作者高明之處,這也是許多佳作常用之法。細(xì)節(jié)描寫(xiě)往往會(huì)成為事情的切入點(diǎn)和突破口,一篇佳作往往離不開(kāi)一些細(xì)節(jié)描寫(xiě),本文也不例外,有些細(xì)節(jié)描寫(xiě)耐人尋味,如:“德國(guó)人撤退時(shí)炸毀的布熱金卡毒氣室和焚尸爐廢墟上,雛菊花在怒放。”“這是一個(gè)二十多歲的姑娘,長(zhǎng)得豐滿,可愛(ài),皮膚細(xì)白,金發(fā)碧眼。她在溫和地微笑著,似乎是為著一個(gè)美好而又隱秘的夢(mèng)想而微笑?!?.句子賞析:“對(duì)另外一些人來(lái)說(shuō),這樣一個(gè)事實(shí)使他們終生難忘:在德國(guó)人撤退時(shí)炸毀的布熱金卡毒氣室和焚尸爐廢墟上,雛菊花在怒放?!泵鞔_:一邊是戕害生命的毒氣室和焚尸爐,一邊是生機(jī)勃勃的生命,兩種反差極大的事物擺在一起。表達(dá)了作者對(duì)納粹的諷刺:納粹的殘暴終歸阻止不了生命的進(jìn)程。同時(shí)也表達(dá)了作者的控訴:生命的綻放是人世間最美好的事情,對(duì)生命的戕害是最惡劣的罪行。
一、教學(xué)目標(biāo)1.指導(dǎo)學(xué)生以一顆真摯的童心、愛(ài)心面對(duì)大自然,促使學(xué)生的心靈與大自然親切交流。2.使學(xué)生明確寫(xiě)景文章的寫(xiě)作范圍、寫(xiě)作重點(diǎn)、構(gòu)思技巧。二、教學(xué)重難點(diǎn)明確話題,寫(xiě)景抓住特征,注重感情。三、教學(xué)方法多重對(duì)話法四、教學(xué)過(guò)程1.導(dǎo)入語(yǔ):自然是人類生活的環(huán)境,是人類賴以生存的基礎(chǔ)。人類不僅在物質(zhì)上需要大地母親的哺育,而且在精神上也需要向自然尋求依托。當(dāng)知時(shí)節(jié)的春雨飄落大地時(shí),當(dāng)秋風(fēng)吹來(lái)誘人的果香時(shí),感到喜悅、幸福的決不僅是農(nóng)民;過(guò)去的政治家、文學(xué)家,每當(dāng)失意的時(shí)候,就會(huì)寄情山林;就是我們中學(xué)生,當(dāng)不堪學(xué)習(xí)重負(fù),感到身心疲憊的時(shí)候,去野外踏青,不也能愉悅身心嗎?可以說(shuō)人對(duì)自然的情懷是與生俱來(lái)的。但不同的人,對(duì)自然的感悟有深淺不同,情趣有高下之分?!叭f(wàn)類霜天競(jìng)自由”的感悟,“大漠孤煙直”的審美不是人人都能有的。2.面對(duì)大自然,通過(guò)什么樣的手段來(lái)促使我們的感悟、審美向高深方向發(fā)展呢?哪位同學(xué)說(shuō)說(shuō)。

三、教學(xué)建議第一課時(shí):1. Lead in (Vocabulary)A) Before class, teacher should collect some pictures of working places. For example: Bank, TV Station, Restaurant, Police Station, Hospital ...B) In class, show students the pictures (PowerPoint, OHP). Ask students to tell the name of the working places and the name of the jobs.Shop assistant, doctor, actor, reporter, police office, waiter, bank clerk, studentC) Do exercise 1a and 3a.2. Bingo GameAsk groups of students to make up pairs of cards with a job on one and the related workplace on the other. For example, waiter / restaurant, teacher / school, doctor / hospital. Encourage students to use both the job / workplace combinations in the book and the ones that students came up during class discussions. Be sure they have twice as many sets of cards as there are students in the group. They can make two sets of cards for a single job / workplace, if necessary. Then have each group mix up its set of cards and hand their cards out in random order. Each time a student gets a pair of cards that match, he or she can lay these cards down. The goal is to have no cards in your hand at the end.3. Task OneA) Ask students to work in pairs and ask the partner what does he / she want to be in the future.e. g. :What do you / does he / does she want to be?I want to be a.Why?Because it's (adj).B) Vocabulary: Section B, 1a4.
