    我們知道數(shù)列是一種特殊的函數(shù),在函數(shù)的研究中,我們在理解了函數(shù)的一般概念,了解了函數(shù)變化規(guī)律的研究內(nèi)容(如單調(diào)性,奇偶性等)后,通過研究基本初等函數(shù)不僅加深了對函數(shù)的理解,而且掌握了冪函數(shù),指數(shù)函數(shù),對數(shù)函數(shù),三角函數(shù)等非常有用的函數(shù)模型。類似地,在了解了數(shù)列的一般概念后,我們要研究一些具有特殊變化規(guī)律的數(shù)列,建立它們的通項公式和前n項和公式,并應(yīng)用它們解決實際問題和數(shù)學(xué)問題,從中感受數(shù)學(xué)模型的現(xiàn)實意義與應(yīng)用,下面,我們從一類取值規(guī)律比較簡單的數(shù)列入手。新知探究1.北京天壇圜丘壇,的地面有十板布置,最中間是圓形的天心石,圍繞天心石的是9圈扇環(huán)形的石板,從內(nèi)到外各圈的示板數(shù)依次為9,18,27,36,45,54,63,72,81 ①2.S,M,L,XL,XXL,XXXL型號的女裝上對應(yīng)的尺碼分別是38,40,42,44,46,48 ②3.測量某地垂直地面方向上海拔500米以下的大氣溫度,得到從距離地面20米起每升高100米處的大氣溫度(單位℃)依次為25,24,23,22,21 ③

    情景導(dǎo)學(xué)古語云:“勤學(xué)如春起之苗,不見其增,日有所長”如果對“春起之苗”每日用精密儀器度量,則每日的高度值按日期排在一起,可組成一個數(shù)列. 那么什么叫數(shù)列呢?二、問題探究1. 王芳從一歲到17歲,每年生日那天測量身高,將這些身高數(shù)據(jù)(單位:厘米)依次排成一列數(shù):75,87,96,103,110,116,120,128,138,145,153,158,160,162,163,165,168 ①記王芳第i歲的身高為 h_i ,那么h_1=75 , h_2=87, 〖"…" ,h〗_17=168.我們發(fā)現(xiàn)h_i中的i反映了身高按歲數(shù)從1到17的順序排列時的確定位置,即h_1=75 是排在第1位的數(shù),h_2=87是排在第2位的數(shù)〖"…" ,h〗_17 =168是排在第17位的數(shù),它們之間不能交換位置,所以①具有確定順序的一列數(shù)。2. 在兩河流域發(fā)掘的一塊泥板(編號K90,約生產(chǎn)于公元前7世紀(jì))上,有一列依次表示一個月中從第1天到第15天,每天月亮可見部分的數(shù):5,10,20,40,80,96,112,128,144,160,176,192,208,224,240. ②

    三、教師總結(jié):在那如火如荼的苦難歲月,梁任公的政治主張屢屢因時而變,但為人處世的原則始終未變,他不是馮自由等人所描述的那種變色龍。他重感情,輕名利,嚴(yán)于律己,坦誠待人。無論是做兒子、做丈夫、做學(xué)生,還是做父親、做師長、做同事,他都能營造一個磁場,亮出一道風(fēng)景。明鏡似水,善解人意是他的常態(tài),在某些關(guān)鍵時刻,則以大手筆寫實愛的海洋,讓海洋為寬容而定格,人間為之增色。我敢斷言,在風(fēng)云際會和星光燦爛的中國近代人才群體中,特別是在遐邇有知的重量級歷史人物中,能在做人的問題上與梁啟超比試者是不大容易找到的。四、課后作業(yè):找出文中細節(jié)及側(cè)面描寫的地方,想一想這樣寫有什么好處,總結(jié)本文的寫作特點。五、板書設(shè)計:梁任公演講特點:

    新人教版高中英語必修3Unit 1 Festivals and Celebrations-Listening &Speaking&Talking教學(xué)設(shè)計

    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. In addition to the use of the -ing form and the past participle, the teacher should guide the students in the appreciation of these statements, ask them to memorize them, and encourage them to use them reasonably in writing practice.

    The topic of this part is “Write about your festival experience”.During the Listening and Speaking and Talking, students are just asked to say out their festival experiences such as the Spring Festival, Mid-autumn Day, but this part students will be asked to write down their own festival experiences. During the reading part, it introduces the Naadam Festival in Inner Mongolia Autonomous Region, which can give students a good example to imitate. Students not only learn the festival, but touch and feel the Inner Mongolian’s character, the spirit and cultural atmosphere, which can help students form the cultural awareness and learn to enjoy and value the diversity of Chinese culture.Concretely, the dairy tells the experience that the author spent the Naadam Festival in Inner Mongolia Autonomous Region with his/her friend. The structure is clear. In the opening paragraph, it introduces the topic of the Naadam Festival and the whole feeling. Then it introduces the items of the festival like the ceremony, wrestling and horse racing. Finally, it summarizes this experience. Because this part is a travel journal, we must guide students pay more attention to these details: 1. use the first person. 2. use the past tense to tell the past thing and use the present or future tense to describe the scenery. 3. use the timeline to tell the development. 4. be careful for the author’s psychology, emotion and feeling, etc.1. Read quickly to get main idea; read carefully to get the detailed information about Naadam Festival.2. Learn the structure of the reading article and language.3. Write an article about a festival experience4. Learn to use the psychology, emotions and feeling in the writing.1. Write an article about a festival experience.2.

    氣候變化對健康的影響 氣候變化對人體健康的不良影響是不難發(fā)現(xiàn)的:熱浪沖擊頻繁加重可致死亡率及某些疾病、特別是心臟呼吸系統(tǒng)疾病發(fā)病率增加;對氣候變化敏感的傳染性疾病如瘧疾和登革熱的傳播范圍可能增加。極端氣候事件, 如干旱、水災(zāi)、暴風(fēng)雨等, 使死亡率、傷殘率及傳染病疾病率上升, 并增加社會心理壓力。某些媒介疾病的加重也可能與氣候變化有間接的關(guān)系, 如瘧疾是通過蚊子傳播的疾病,氣候變化可能使某些變暖地區(qū)的蚊子數(shù)目增加, 從而加重了瘧疾的發(fā)生。我國1994年瘧疾的發(fā)病率為5.3408/10萬, 居全國法定傳染病的第六位。血吸蟲病的發(fā)展與高溫及灌溉系統(tǒng)的擴增有關(guān)。我國1994年南方12省市血吸蟲病患者的檢出率高達3.67%,不能忽視氣候變化對此的可能影響。還有一些疾病,如睡眠病、登革熱、黑熱病等也有與氣候關(guān)系的報道。另外, CO2、一些空氣污染物如氮氧化物、臭氧等可增加過敏疾患及心臟呼吸系統(tǒng)疾病和死亡。

    人教版高中地理必修1冷熱不均引起的大氣運動教案

    討論:二氧化碳在大氣的受熱過程中起到了什么作用?(吸收太陽輻射中的紅外線輻射和地面輻射,保溫作用)大氣中的二氧化碳濃度增大對氣溫有什么影響?(全球氣候變暖)閱讀:我們知道了太陽輻射中的可見光和紅外 光能量的吸收和轉(zhuǎn)化,那么紫外區(qū)的能量到哪兒去了?請同學(xué)們查閱資料,自主探討。小結(jié):大氣的受熱過 程就是太陽曬熱了地面,地面烘熱了大氣。太陽輻射是大氣的根本熱源,地面輻射是大氣的直接熱源。這就是為什么海拔越高,氣溫越低的原因,難怪高處不勝寒!轉(zhuǎn)承:大氣的直接熱源是地面,不同性質(zhì)的地面溫度是不同的,同緯度,海洋和陸地就有溫差。提問:請學(xué)生說說白天和晚上在海邊的不同感受。由白天和晚上的風(fēng)向不同切入實驗P32活動。討論:通過煙霧的飄動,我們得出了什么規(guī)律?冷熱不均引起了熱力環(huán)流板書: 二、熱力環(huán)流板圖與分析:結(jié)合試驗,學(xué)生分析熱力環(huán)流 的產(chǎn)生

  • 人教版高中地理必修1自然地理環(huán)境的整體性教案

    人教版高中地理必修1自然地理環(huán)境的整體性教案

    1.生產(chǎn)功能:合成有機物的能力2.平衡功能:使自然地理要素的性質(zhì)保持穩(wěn)定的能力【教師講解】生產(chǎn)功能主要依賴于光合作用。在光合作用過程中,植物提供葉綠素,大氣提供熱量和二氧化碳,土壤及水圈、巖石圈提供水分及無機鹽。光合作用通過物質(zhì)和能量的交換,將生物、大氣、水、土壤、巖石等地理要素統(tǒng)一在一起,在一定的條件下,生產(chǎn)出有機物。由此可見,生產(chǎn)功能是自然環(huán)境的整體功能而非單個地理要素的功能。大氣本身不具有減緩二氧化碳增加的功能,但是,在自然地理環(huán)境中,通過各地理要素的相互作用,卻能消除部分新增的二氧化碳的能力,既為自然地理環(huán)境的平衡功能。請大家閱讀教材P94活動,利用平衡功能的原理,解釋一定范圍內(nèi)各物種的數(shù)量基本恒定這一現(xiàn)象?!緦W(xué)生討論回答】略。(可參考教參)【轉(zhuǎn)折】自然地理環(huán)境各要素每時每刻都在演化,如我們熟知的氣候變化、地貌變化等。各個要素的發(fā)展演化是統(tǒng)一的,一個要素的演化伴隨著其他各個要素的演化。
