解析:因?yàn)闇p法和除法運(yùn)算中交換兩個(gè)數(shù)的位置對(duì)計(jì)算結(jié)果有影響,所以屬于組合的有2個(gè).答案:B2.若A_n^2=3C_(n"-" 1)^2,則n的值為( )A.4 B.5 C.6 D.7 解析:因?yàn)锳_n^2=3C_(n"-" 1)^2,所以n(n-1)=(3"(" n"-" 1")(" n"-" 2")" )/2,解得n=6.故選C.答案:C 3.若集合A={a1,a2,a3,a4,a5},則集合A的子集中含有4個(gè)元素的子集共有 個(gè). 解析:滿足要求的子集中含有4個(gè)元素,由集合中元素的無(wú)序性,知其子集個(gè)數(shù)為C_5^4=5.答案:54.平面內(nèi)有12個(gè)點(diǎn),其中有4個(gè)點(diǎn)共線,此外再無(wú)任何3點(diǎn)共線,以這些點(diǎn)為頂點(diǎn),可得多少個(gè)不同的三角形?解:(方法一)我們把從共線的4個(gè)點(diǎn)中取點(diǎn)的多少作為分類的標(biāo)準(zhǔn):第1類,共線的4個(gè)點(diǎn)中有2個(gè)點(diǎn)作為三角形的頂點(diǎn),共有C_4^2·C_8^1=48(個(gè))不同的三角形;第2類,共線的4個(gè)點(diǎn)中有1個(gè)點(diǎn)作為三角形的頂點(diǎn),共有C_4^1·C_8^2=112(個(gè))不同的三角形;第3類,共線的4個(gè)點(diǎn)中沒(méi)有點(diǎn)作為三角形的頂點(diǎn),共有C_8^3=56(個(gè))不同的三角形.由分類加法計(jì)數(shù)原理,不同的三角形共有48+112+56=216(個(gè)).(方法二 間接法)C_12^3-C_4^3=220-4=216(個(gè)).

一、說(shuō)教材《古詩(shī)三首》是統(tǒng)編小學(xué)語(yǔ)文三年級(jí)下冊(cè)第一單元中的第一篇課文。《絕句》這首詩(shī)抓住遲日、江山、春風(fēng)、花草等景物給讀者描繪了一幅明麗紛繁的春景圖，表達(dá)了詩(shī)人對(duì)初春時(shí)節(jié)大自然一派生機(jī)、欣欣向榮景象的贊美與熱愛(ài)。 《惠崇春江晚景》成功地寫(xiě)出了早春時(shí)節(jié)的春江景色，詩(shī)人以其細(xì)致、敏銳的感受，捕捉住季節(jié)轉(zhuǎn)換時(shí)的景物特征，抒發(fā)了對(duì)早春的喜悅和贊美之情。 《三衢道中》通過(guò)寫(xiě)詩(shī)人行于三衢山道中的見(jiàn)聞，在景物的描繪中融入了自己愉悅的心情，表達(dá)了詩(shī)人對(duì)大自然之美的喜悅與贊美。本單元的主題是通過(guò)對(duì)學(xué)生進(jìn)行美的熏陶，培養(yǎng)學(xué)生熱愛(ài)大自然的情感。二、說(shuō)學(xué)情 三年級(jí)的學(xué)生有了一定的古詩(shī)學(xué)習(xí)經(jīng)驗(yàn)，學(xué)生掌握了一定的古詩(shī)學(xué)習(xí)的方法。為此我讓學(xué)生自主探究，合作交流本詩(shī)。
（說(shuō)課稿）部編人教版三年級(jí)下冊(cè)《童年的水墨畫(huà)》
一、說(shuō)教材《童年的水墨畫(huà)》是統(tǒng)編小學(xué)語(yǔ)文三年級(jí)下冊(cè)第六單元的一篇精讀課文，本文是一組兒童詩(shī)，由詩(shī)人張繼樓的《溪邊》《江上》《林中》三首小詩(shī)組成，以跳躍的鏡頭捕捉了鄉(xiāng)村兒童的典型生活場(chǎng)景，展現(xiàn)了兒童生活的豐富多彩以及無(wú)窮趣味。 《溪邊》一詩(shī)生動(dòng)形象地描繪了兒童垂釣的場(chǎng)景。詩(shī)歌先描繪平靜的溪水把人影染“綠”，再寫(xiě)水面釣竿上立著一只“紅”蜻蜓，這一“綠”一“紅”，既是和諧唯美的相互映襯，又是恰到好處的點(diǎn)綴，使畫(huà)面充滿了色彩美感；接下來(lái)，描繪了靜靜的溪水映著柳樹(shù)、釣魚(yú)孩子的倒影、釣魚(yú)竿、紅蜻蜓，空氣都仿佛停止了流動(dòng)，直到魚(yú)兒上鉤的一剎那，溪水動(dòng)了，人影碎了，魚(yú)躍人歡，畫(huà)面頓時(shí)變得生機(jī)盎然。這一靜一動(dòng)的結(jié)合，是本詩(shī)的微妙高明之處。 《江上》描摹了一群水鄉(xiāng)孩子江中嬉戲的歡樂(lè)場(chǎng)面。一群戲水的孩子，那樣的調(diào)皮，像鴨群一樣鉆入水中，接下來(lái)“一陣水花”與“兩排銀牙”，將童年的爛漫快樂(lè)渲染得淋漓盡致，鮮活的畫(huà)面仿佛定格在我們的腦海之中。

三、說(shuō)教學(xué)重難點(diǎn)1.了解海底景色奇異和物產(chǎn)豐富的特點(diǎn)。（重點(diǎn)）2.通過(guò)語(yǔ)言文字展開(kāi)想象，再現(xiàn)課文所描寫(xiě)的情景。（重點(diǎn)）3.激發(fā)學(xué)生熱愛(ài)自然，探索自然界奧秘的興趣。（難點(diǎn)）四、說(shuō)教法學(xué)法[說(shuō)教法]一堂好的語(yǔ)文課應(yīng)充分體現(xiàn)“書(shū)聲朗朗，議論紛紛，高潮迭起，讀讀寫(xiě)寫(xiě)”這十六個(gè)字。針對(duì)以上教學(xué)思想，本文的教學(xué)我主要選用“自學(xué)研究”式的教學(xué)方法，主要依據(jù)是這樣能使學(xué)生主動(dòng)參加到研究過(guò)程中，培養(yǎng)學(xué)生創(chuàng)新意識(shí)和自學(xué)能力，體現(xiàn)老師為主導(dǎo)，學(xué)生為主體的新課改思想。再輔之議論法和情景感染法，真正把語(yǔ)文上成語(yǔ)文素質(zhì)教育課。[說(shuō)學(xué)法]“向?qū)W生傳授學(xué)法，讓學(xué)生學(xué)會(huì)”是教學(xué)這節(jié)課的真正目的。根據(jù)教材和學(xué)生的認(rèn)知水平，主要向?qū)W生滲透自學(xué)的方法，讓學(xué)生會(huì)讀書(shū)，重視朗讀，組織學(xué)生多種形式的讀。在多讀的基礎(chǔ)上，通過(guò)學(xué)生想、劃、議等活動(dòng)，調(diào)動(dòng)學(xué)生積極思維。

三、說(shuō)教學(xué)重難點(diǎn)1.能積累描寫(xiě)表現(xiàn)陶罐、鐵罐神態(tài)和動(dòng)作的詞句，積累語(yǔ)言。（重點(diǎn)）2.在分角色、有感情朗讀課文中讀懂課文內(nèi)容，明白其中的道理。（難點(diǎn)）四、說(shuō)教法學(xué)法[說(shuō)教法]1.指導(dǎo)觀察法遵照學(xué)生的認(rèn)知規(guī)律，充分發(fā)揮文中插圖的作用，以圖帶文、圖文并茂，既激發(fā)了學(xué)生的興趣，也自然地加深了對(duì)課文的學(xué)習(xí)。 2.表演教學(xué)法 針對(duì)小學(xué)生的年齡特點(diǎn)，采用表演讀，旨在創(chuàng)設(shè)良好的學(xué)習(xí)環(huán)境，調(diào)動(dòng)學(xué)生的興趣，誘發(fā)學(xué)生的情感，使他們投入課文所設(shè)置的情境中。 3.鼓勵(lì)欣賞法 教師及時(shí)的點(diǎn)評(píng)，甚至學(xué)生之間的互評(píng)，都是以鼓勵(lì)、欣賞為主，主要是激勵(lì)學(xué)生充分地展示才能，滿足他們希望得到贊許，體會(huì)成功的心理特點(diǎn)，激起學(xué)生學(xué)習(xí)的欲望，增強(qiáng)朗讀的信心。
