直線的一般式方程教學(xué)設(shè)計人教A版高中數(shù)學(xué)選擇性必修第一冊
解析:當(dāng)a0時,直線ax-by=1在x軸上的截距1/a0,在y軸上的截距-1/a>0.只有B滿足.故選B.答案:B 3．過點(1,0)且與直線x－2y－2＝0平行的直線方程是( ) A．x－2y－1＝0 B．x－2y＋1＝0C．2x＋y＝2＝0 D．x＋2y－1＝0答案A 解析：設(shè)所求直線方程為x－2y＋c＝0，把點(1,0)代入可求得c＝－1.所以所求直線方程為x－2y－1＝0.故選A.4．已知兩條直線y＝ax－2和3x－(a＋2)y＋1＝0互相平行，則a＝________.答案：1或－3 解析：依題意得：a(a＋2)＝3×1，解得a＝1或a＝－3.5．若方程(m2－3m＋2)x＋(m－2)y－2m＋5＝0表示直線．(1)求實數(shù)m的范圍；(2)若該直線的斜率k＝1，求實數(shù)m的值．解析： (1)由m2－3m＋2＝0，m－2＝0，解得m＝2，若方程表示直線，則m2－3m＋2與m－2不能同時為0，故m≠2.(2)由－?m2－3m＋2?m－2＝1，解得m＝0.

新知探究前面我們研究了兩類變化率問題：一類是物理學(xué)中的問題，涉及平均速度和瞬時速度；另一類是幾何學(xué)中的問題，涉及割線斜率和切線斜率。這兩類問題來自不同的學(xué)科領(lǐng)域，但在解決問題時，都采用了由“平均變化率”逼近“瞬時變化率”的思想方法；問題的答案也是一樣的表示形式。下面我們用上述思想方法研究更一般的問題。探究1： 對于函數(shù)y=f(x) ，設(shè)自變量x從x_0變化到x_0+ ?x ，相應(yīng)地，函數(shù)值y就從f(x_0)變化到f(〖x+x〗_0) 。這時， x的變化量為?x，y的變化量為?y=f(x_0+?x)-f(x_0)我們把比值?y/?x，即?y/?x=(f(x_0+?x)-f(x_0)" " )/?x叫做函數(shù)從x_0到x_0+?x的平均變化率。1．導(dǎo)數(shù)的概念如果當(dāng)Δx→0時，平均變化率ΔyΔx無限趨近于一個確定的值，即ΔyΔx有極限，則稱y＝f (x)在x＝x0處____，并把這個________叫做y＝f (x)在x＝x0處的導(dǎo)數(shù)(也稱為__________)，記作f ′(x0)或________，即

二、典例解析例10. 如圖，正方形ABCD 的邊長為5cm ，取正方形ABCD 各邊的中點E,F,G,H, 作第2個正方形 EFGH，然后再取正方形EFGH各邊的中點I,J,K,L，作第3個正方形IJKL ，依此方法一直繼續(xù)下去. (1) 求從正方形ABCD 開始，連續(xù)10個正方形的面積之和；(2) 如果這個作圖過程可以一直繼續(xù)下去，那么所有這些正方形的面積之和將趨近于多少？分析：可以利用數(shù)列表示各正方形的面積，根據(jù)條件可知，這是一個等比數(shù)列。解：設(shè)正方形的面積為a_1，后續(xù)各正方形的面積依次為a_2, a_(3, ) 〖…,a〗_n,…，則a_1=25,由于第k+1個正方形的頂點分別是第k個正方形各邊的中點，所以a_(k+1)=〖1/2 a〗_k,因此{(lán)a_n}，是以25為首項，1/2為公比的等比數(shù)列.設(shè){a_n}的前項和為S_n（1）S_10=(25×[1-(1/2)^10 ] )/("1 " -1/2)=50×[1-(1/2)^10 ]=25575/512所以，前10個正方形的面積之和為25575/512cm^2.(2)當(dāng)無限增大時，無限趨近于所有正方形的面積和

二、典例解析例4. 用 10 000元購買某個理財產(chǎn)品一年.（1）若以月利率0.400%的復(fù)利計息，12個月能獲得多少利息（精確到1元）？（2）若以季度復(fù)利計息，存4個季度，則當(dāng)每季度利率為多少時，按季結(jié)算的利息不少于按月結(jié)算的利息（精確到10^(-5)）？分析：復(fù)利是指把前一期的利息與本金之和算作本金，再計算下一期的利息.所以若原始本金為a元，每期的利率為r ，則從第一期開始，各期的本利和a , a(1+r)，a(1+r)^2…構(gòu)成等比數(shù)列.解：（1）設(shè)這筆錢存 n 個月以后的本利和組成一個數(shù)列{a_n }，則{a_n }是等比數(shù)列，首項a_1=10^4 (1+0.400%)，公比 q=1+0.400%，所以a_12=a_1 q^11 〖=10〗^4 (1+0.400%)^12≈10 490.7.所以，12個月后的利息為10 490.7-10^4≈491（元）.解：（2）設(shè)季度利率為 r ，這筆錢存 n 個季度以后的本利和組成一個數(shù)列{b_n }，則{b_n }也是一個等比數(shù)列，首項 b_1=10^4 (1+r)，公比為1+r，于是 b_4=10^4 (1+r)^4.

二、典例解析例3.某公司購置了一臺價值為220萬元的設(shè)備，隨著設(shè)備在使用過程中老化，其價值會逐年減少.經(jīng)驗表明，每經(jīng)過一年其價值會減少d(d為正常數(shù)）萬元.已知這臺設(shè)備的使用年限為10年，超過10年 ，它的價值將低于購進(jìn)價值的5%，設(shè)備將報廢.請確定d的范圍.分析：該設(shè)備使用n年后的價值構(gòu)成數(shù)列{an}，由題意可知，an＝an－1－d (n≥2). 即：an－an－1＝－d.所以{an}為公差為－d的等差數(shù)列.10年之內(nèi)（含10年），該設(shè)備的價值不小于（220×5%=）11萬元；10年后，該設(shè)備的價值需小于11萬元．利用{an}的通項公式列不等式求解．解：設(shè)使用n年后，這臺設(shè)備的價值為an萬元，則可得數(shù)列{an}．由已知條件，得an＝an－1－d（n≥2）．所以數(shù)列{an}是一個公差為－d的等差數(shù)列.因為a1＝220－d，所以an＝220－d＋(n－1)(－d)＝220－nd. 由題意，得a10≥11，a11＜11. 即：{█("220－10d≥11" @"220－11d＜11" )┤解得19<d≤20.9所以，d的求值范圍為19<d≤20.9
關(guān)于品德是人的第一智慧的第三周國旗下講話
德是人的第一智慧—第三周國旗下講話各位老師、同學(xué)們：大家早晨好！我今天講話的題目是《品德是人的第一智慧》，側(cè)重闡述品德和智慧的關(guān)系，強(qiáng)調(diào)我校學(xué)生在校期間的品德要求。我們今天培養(yǎng)和選拔人才的標(biāo)準(zhǔn)是德才兼?zhèn)?，但很少有人思考“德”和“才”的關(guān)系?？梢赃@樣講，一個人有怎樣的品德，就會有怎樣的人生理解和目標(biāo)，而智慧決定的是追求目標(biāo)的途徑和方法。目標(biāo)決定方法，方法服務(wù)于目標(biāo)。從這個意義上講，品德是成功人生的前提，是第一位的；智慧是成功人生的必須，從屬于品德。翻開一部人類的歷史，凡被人們敬仰的偉人，哪一位不是品德高尚的人？毛澤東、孫中山、錢學(xué)森、華羅庚、羅斯福、華盛頓、愛因斯坦、哥白尼等等。同學(xué)們試想想，如果你走向社會后事業(yè)有成，你會選擇一位當(dāng)年缺乏公德的同學(xué)合作嗎？沒有與人良好的合作關(guān)系，才高八斗又有何用？高尚的品德不是與生俱來的，他需要我們一點一滴的做好自律，并自覺接受它律。自律的最高境界就是中國儒家文化強(qiáng)調(diào)的“慎獨”，即一個人獨處時也能保持同樣的高尚品德境界，而不是沒人看見就隨手扔垃圾，隨性破壞公物或干點什么見不得人的壞事。

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.

Step 3 Analyzing article structureActivity 31. Teachers raise questions to guide students to analyze the chapter structure of this diary and think about how to describe the festival experience. (1)What should be included in the opening/body/closing paragraph(s)?(2)How did the writer arrange his/her ideas?(3)What kind of interesting details did the writer describe?(4)How did the writer describe his/her feelings/emotions during the event?2. Students read and compare the three sentence patterns in activity 2. Try to rewrite the first paragraph of the diary with these three sentence patterns. After that, students exchange corrections with their partners. Such as:●This was my first time spending three days experiencing the Naadam Festival in China’s Inner Mongolia Autonomous Region and it was an enjoyable and exciting experience. ●I'll never forget my experience at the Naadam Festival because it was my first time to watch the exciting Mongolian games of horse racing, wrestling, and archery so closely. ●I'll always remember my first experience at the Naadam Festival in China’s Inner Mongolia Autonomous Region because it was so amazing to spend three days witnessing a grand Mongolian ceremony. Step 4 Accumulation of statementsActivity 41. Ask the students to read the diary again. Look for sentences that express feelings and emotions, especially those with the -ing form and the past participle. Such as:● …h(huán)orse racing, wrestling, and archery, which are all so exciting to watch. ● some amazing performances● I was surprised to see…● I was a little worried about. . . ● feeling really tiredOther emotional statements:●I absolutely enjoyed the archery, too, but the horse races were my favourite part. ●I'm finally back home now, feeling really tired, but celebrating Naadam with my friend was totally worth it. ●He invited me back for the winter to stay in a traditional Mongolian tent and cat hot pot. I can’t wait!2.
