點(diǎn)到直線的距離公式教學(xué)設(shè)計(jì)人教A版高中數(shù)學(xué)選擇性必修第一冊(cè)
4.已知△ABC三個(gè)頂點(diǎn)坐標(biāo)A(－1,3)，B(－3,0)，C(1,2)，求△ABC的面積S.【解析】由直線方程的兩點(diǎn)式得直線BC的方程為 ＝ ，即x－2y＋3＝0，由兩點(diǎn)間距離公式得|BC|＝ ，點(diǎn)A到BC的距離為d，即為BC邊上的高，d＝ ，所以S＝ |BC|·d＝ ×2 × ＝4，即△ABC的面積為4.5.已知直線l經(jīng)過點(diǎn)P(0,2),且A(1,1),B(-3,1)兩點(diǎn)到直線l的距離相等,求直線l的方程.解:(方法一)∵點(diǎn)A(1,1)與B(-3,1)到y(tǒng)軸的距離不相等,∴直線l的斜率存在,設(shè)為k.又直線l在y軸上的截距為2,則直線l的方程為y=kx+2,即kx-y+2=0.由點(diǎn)A(1,1)與B(-3,1)到直線l的距離相等,∴直線l的方程是y=2或x-y+2=0.得("|" k"-" 1+2"|" )/√(k^2+1)=("|-" 3k"-" 1+2"|" )/√(k^2+1),解得k=0或k=1.(方法二)當(dāng)直線l過線段AB的中點(diǎn)時(shí),A,B兩點(diǎn)到直線l的距離相等.∵AB的中點(diǎn)是(-1,1),又直線l過點(diǎn)P(0,2),∴直線l的方程是x-y+2=0.當(dāng)直線l∥AB時(shí),A,B兩點(diǎn)到直線l的距離相等.∵直線AB的斜率為0,∴直線l的斜率為0,∴直線l的方程為y=2.綜上所述,滿足條件的直線l的方程是x-y+2=0或y=2.

人教版高中歷史必修3文藝復(fù)興和宗教改革教案
三、宗教改革：1、背景：（1）文藝復(fù)興的影響。文藝復(fù)興中，人文主義學(xué)者盡管對(duì)宗教保持較為溫和的態(tài)度，但其以人為中心的思想極大地沖擊了天主教的精神獨(dú)裁，天主教的權(quán)威日益受到人們的懷疑。（2）天主教會(huì)對(duì)歐洲尤其是德意志的壓榨。中世紀(jì)的天主教會(huì)對(duì)人民進(jìn)行嚴(yán)密的精神統(tǒng)治，基督教信仰的核心是“原罪”和“靈魂救贖”，即人生下來就有罪，只有信仰上帝，跟隨耶穌才能得救。就“靈魂救贖”而言，最初強(qiáng)調(diào)的是個(gè)人信仰的作用，后來，神學(xué)家們又加上了種種繁雜的宗教禮儀，而且必須得到神職人員的幫助，靈魂才能得救。在經(jīng)濟(jì)上，天主教會(huì)還是最大的封建主，占有大量的土地，并征收什一稅，對(duì)各國人民大肆搜刮。羅馬教廷每年從德意志搜刮的財(cái)富達(dá)30萬古爾登（貨幣單位），相當(dāng)于“神圣羅馬帝國”皇帝每年稅收額的20倍。德意志也成了被教會(huì)榨取最嚴(yán)重的地區(qū)，素有“教皇的乳?！敝Q。

“千載琵琶作胡語，分明怨恨曲中論?！薄霸购蕖眱勺贮c(diǎn)明全篇主旨。千百年來，琵琶所演奏的總是從匈奴傳來的撩人愁思的胡樂，正是昭君在訴說著她的怨恨！這兩句從側(cè)面烘托昭君的形象，既有對(duì)她的贊揚(yáng)，又有對(duì)她的同情。讀到這里，我們的耳邊好像又響起了那深沉、幽怨的琵琶聲！5、這首詩寫的是昭君的怨恨，但首聯(lián)一開始并沒有寫她的怨恨，寫的是什么？這樣寫的目的又是什么？明確：群山萬壑赴荊門山是群山起伏，連綿不絕；水是萬壑爭流，奔騰不息，直赴荊門山。其中的“赴”字用了擬人的手法，把迤邐不絕的千山萬壑陡然間寫活了，既有飛動(dòng)之勢(shì)，又有變幻之姿。從側(cè)面烘托昭君的形象。兩千多年前，一個(gè)青年女子遠(yuǎn)離父母之邦，嫁到異域，并在那里度過一生，確實(shí)需要巨大的勇氣和毅力，而這雄偉的山川簡直就是她那堅(jiān)強(qiáng)的性格的象征。6、佳句鑒賞（這首詩歌當(dāng)中，我認(rèn)為有兩句詩寫得非常美，我自己很喜歡，不知道有沒有同道中人？）

人教版高中歷史必修3充滿魅力的書畫和戲曲藝術(shù)教案
乾隆五十五年（公元1790年），在安徽一帶很有名氣的“三慶”徽戲班，來到北京演出。徽戲在北京經(jīng)常和其他劇種同臺(tái)演出，注意吸收和借鑒他們的長處。尤其是與以唱二黃調(diào)和西皮調(diào)為主的漢戲的合演，逐漸形成了二黃與西皮的合流，形成了“徽漢合流”的局面，后來徽劇又吸收其他民間曲調(diào)的唱腔、劇目和表演方式，逐漸形成以“皮黃”為主要聲腔的京劇。到1840年左右，京劇的唱腔、念白、劇本和表演已經(jīng)成熟，尤其是出現(xiàn)了以演“京戲”為主的一批演員，他們不再以徽戲、漢戲?yàn)槊?，而以演“京戲”自居。從此，誕生了一個(gè)獨(dú)立的劇種──京劇。2、京劇的發(fā)展早期的京劇以迷人的唱腔、豐富的劇目、精彩的表演和京腔京味吸引了觀眾，使京城出現(xiàn)了京劇熱。同治、光緒年間，京劇已經(jīng)被京城市民承認(rèn)，成為人們最喜愛的舞臺(tái)藝術(shù)。并涌現(xiàn)出著名的“同光十三絕”。

新人教版高中英語必修3Unit 1 Festivals and Celebrations-Listening &Speaking＆Talking教學(xué)設(shè)計(jì)
The theme of this section is “Talk about festival activities and festival experiences”.Festival and holiday is a relaxing and interesting topic for students. This part talks about the topic from the daily life of students’. In the part A ---Listening and Speaking, there are three conversations among different speakers from three countries(Japan, Rio and China), where the speakers are participating in or going to participate in the festivals and celebrations. So listening for the relationship among them is a fundamental task. Actually, with the globalization and more international communication, it is normal for Chinese or foreigners to witness different festivals and celebrations in or out of China. In the Conversation 1, a foreign reporter is interviewing a Japanese young girl who just had participated in the ceremony of the Coming-of-Age Day on the street and asking her feeling about the ceremony and the afterwards activities. Conversation 2, Chinese girl Li Mei is witnessing the Rio Carnival for the first time, and her friend Carla gives her some advice on the costumes which enables her to match with the carnival to have a good time. Conversation 3, a Chinese guide is showing a group of foreign visitors around the Lantern Festival and introducing the customs of the festival to them. The three conversations have a strong vitality and insert the festival and cultural elements from different countries. So perceiving the festivals and cultures from different countries is the second task. At the same time, the scripts also insert the targeted grammar --- v-ing as attributive and predicative, which students can perceive and experience in a real context and make a road for the further study. That is the third task. In the Part B--- Listening and Talking, the theme is “Talk about festival experience”, which is the common topic in our daily conversations. During the conversation, Song Lin, a Chinese student, asked Canadian friend Max about how to spend Christmas. In the conversation, Song Lin talked about experience and the feelings during the Chinese Spring Festival, during which there are not only some enjoyable things but some unpleasant things. After the listening, perhaps students find there are some similarities between Christmas and the Chinese Spring Festival as there are some differences in the origins and celebrations. For example, people always visit friends and relatives, decorate their houses, have a big dinner together, chat and give presents to each other.
