例7 用描述法表示拋物線y＝x2＋1上的點構(gòu)成的集合．【答案】見解析 【解析】 拋物線y＝x2＋1上的點構(gòu)成的集合可表示為：{(x，y)|y＝x2＋1}．變式1．[變條件，變設問]本題中點的集合若改為“{x|y＝x2＋1}”，則集合中的元素是什么？【答案】見解析 【解析】集合{x|y＝x2＋1}的代表元素是x，且x∈R，所以{x|y＝x2＋1}中的元素是全體實數(shù)．變式2．[變條件，變設問]本題中點的集合若改為“{y|y＝x2＋1}”，則集合中的元素是什么？【答案】見解析 【解析】集合{ y| y＝x2＋1}的代表元素是y，滿足條件y＝x2＋1的y的取值范圍是y≥1，所以{ y| y＝x2＋1}＝{ y| y≥1}，所以集合中的元素是大于等于1的全體實數(shù)．解題技巧（認識集合含義的2個步驟）一看代表元素，是數(shù)集還是點集，二看元素滿足什么條件即有什么公共特性。

新人教版高中英語必修3Unit 1 Festivals and Celebrations-Listening &Speaking＆Talking教學設計
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.

人教版高中歷史必修1甲午中日戰(zhàn)爭和八國聯(lián)軍侵華說課稿
四．設計反思我在設計本課時，希望通過情境的創(chuàng)設充分再現(xiàn)歷史，并利用多媒體輔助教學，破重點、化難點，讓學生主動參與到學習過程中，從而突破狹小的教室空間，讓學生真正做到感知歷史，立足現(xiàn)實，展望未來。自主，交流、合作、探究是課程改革中著力倡導的新型學習方式。課堂教學中如何開展小組合作的探究學習存在著很多困難，首先是課堂教學時間有限，如何體現(xiàn)面向全體，給每個學生以機會？再次，歷史問題的討論只能依托于史料才能使討論不淪為空談，課堂上通過網(wǎng)絡提供大量的史料（文字、圖片或其他），勢必不能有充分時間讓學生閱讀分析。如何解決這些問題呢?措施一：要形成較固定的歷史學習合作小組。選定一位同學擔任組長，負責協(xié)調(diào)措施二：要設置有利于學生探究的問題情境措施三：要把課堂教學與課外學習結(jié)合起來。在課前就印發(fā)相關的材料，或引導學生去查閱相關的資料，讓學生有個充分的閱讀、思考、交流的時間，是保證課堂上小組交流能成功實現(xiàn)的一個前提
人教版高中語文必修1《別了，“不列顛尼亞”》說課稿2篇
一、說教材《別了，不列顛尼亞》是編排在人教版《普通高中課程標準實驗教科書語文1（必修）》第四單元的課文，是精讀課文《短新聞兩篇》中的一篇，另一篇是《奧斯維辛沒有什么新聞》。這一單元的學習內(nèi)容是新聞和報告文學，還有兩篇作品分別是中國報告文學三大里程碑之一的《包身工》和記錄中國航天事業(yè)輝煌發(fā)展的《飛向太空的航程》。在當今信息大爆炸的時代，如何快速獲得信息，如何在新聞中解讀事件的真相，感悟生活的內(nèi)涵成為語文教學的又一重大任務。因此這一單元的編入便更多地具有了時代意義，體現(xiàn)了語文學科與日常生活的密切關系。不僅如此，新聞特寫和報告文學的選入，拓寬了學生對新聞類文章的了解，體現(xiàn)語文學科的工具性作用。在選文的過程中，新教材同時注重語文學科的人文性，四篇作品不僅傳遞著新鮮、真實的信息，同時更張顯人文性的厚度，他們以飽滿的情感，縱橫的歷史經(jīng)驗。

在學習語文經(jīng)驗交流會上，季老師舉著我的《采花釀蜜集》，對大家說：“人日積月累辛勤采擷，終于釀出了知識的瓊漿。大家都應這樣，爭做知識的富戶?。 崩蠋熡悬c激動，低低地爬在鼻梁上的眼鏡突然滑了下來，正好落在那集子上。大家笑了，季老師也笑了。就這樣，我的寫作有了進步，好幾篇作文登上了班級《學作園地》。從此，我愛上了語文，更深深地愛上了季老師。高中升學考前那個星期天的夜晚，季老師舊病復發(fā)，累倒了。半夜，老師們把他送進了公社衛(wèi)生院。第二天，同學們都悄悄去衛(wèi)生院看望。我去的時候，季老師正在掛滴流?？墒?，下午季老師又出現(xiàn)在講臺上，他臉色憔悴，聲音沙啞……我手捧《采花釀蜜集》走近季老師，思緒的溪水從遠方流了回來?！凹纠蠋煛?，我把本子捧給老師，深情地叫了聲。季老師接過本子，仔細翻閱著，臉上露出了笑容，像是聞到了郁郁芳香的蜜汁似的?！斑M步不小呀！”季老師說著，又在本子扉頁上題了

四、教學過程：（一）、課題引入：教師創(chuàng)設問題情景（創(chuàng)設情景：使用多媒體模擬一些比較有趣、與生活實踐比較有關的事，并提出問題。）激發(fā)學生的探究欲望，引導學生提出接下去要研究的問題。（二）、新課教學：1、針對上面提出的問題，安排學生分組討論，讓學生通合作學習探索有關的知識，并進一步引出下面要解決的問題。2、組織學生進行新問題的探究學習，設計上最好是有對比性、通過多媒體的輔助，由學生分析比較，歸納總結(jié)出知識的結(jié)構(gòu)。（三）、實施反饋：1、設計相關習題達到對學過的知識的檢測和鞏固；2、課堂反饋，遷移知識（最好遷移到與生活有關的例子）。讓學生分析有關的問題，實現(xiàn)知識的升華、實現(xiàn)學生的再次創(chuàng)新。五、板書設計：在教學中我把黑板分為兩大部分，左邊是第一部分，各知識點羅列其下，第二部分寫在右邊，各知識點羅列其下。

第11段很短，只點出了這是“在婦女身上搞不育試驗的地方”，但在最末又加了一句“否則他會羞紅了臉的”，這是為什么？那肯定是一個極為骯臟，極為殘酷的地方。據(jù)資料記載：當時的希特勒制定一項令所有被征服或占領國家的民族充當奴隸并且逐漸消亡的隱密性種族滅絕計劃——高效率、大規(guī)模的強制絕育。為此，數(shù)以百計的納粹醫(yī)生、教授、專家甚至護士，在行政管理專家的通力合作下，相繼提出了幾十種絕育方法，十余種實施方案，并且在奧斯維辛、拉芬斯布呂克、布亨瓦爾特、達豪等十多個大型集中營內(nèi)對數(shù)以萬計的猶太、吉普賽囚犯、因從事抵抗運動而被捕的政治犯和男女戰(zhàn)俘進行了殘酷的手術(shù)試驗，造成他們大量死亡或者終身殘疾、終身不育。這樣殘酷的毫無人性的手段，任誰也不愿看到。

二、說學生本屆高一學生經(jīng)過了三年初中課改，在心理上，他們渴望表現(xiàn)的欲望和自主探究的欲望比較強烈，對有興趣的知識表現(xiàn)出高度地熱情，并具有一定的團結(jié)協(xié)作能力，但還是應該正視一個并不樂觀的現(xiàn)實——在寫作方面，學生知識還停留在簡單的記敘及表達方式綜合運用上，至于巧妙構(gòu)思、謀篇布局很是空白。即便已經(jīng)經(jīng)過高中一個學期的學習，但還是有大部分學生依然基礎較為薄弱，甚至出現(xiàn)不知從何下筆的現(xiàn)象。三、說教法與學法“老師搭臺，學生唱戲”１、教法：本課將安排兩課時（一課時學習一課時練筆），采用 PPT 多媒體課件教學，嘗試用角色扮演法、圖片展示法和多媒體教學等方法，教學中應該重視學生的參與性和探究性。２、學法：學生應該充分利用多角度創(chuàng)設的學習情境來激發(fā)自身學習的興趣和熱情，分組討論，小組互助等形式讓學生積極自主參與、進行問題探究學習。理論依據(jù)：建構(gòu)主義理論“學生是學習的中心”的闡釋，教師應該做學生主動建構(gòu)意義的幫助者、促進者。
人教版高中語文必修1《新詞新語與流行文化》說課稿
當代社會生活的變化比以往任何時代都要快。語言尤其是詞匯記錄了這些發(fā)展變化，因而也涌現(xiàn)了大量的新詞新語。據(jù)統(tǒng)計，近幾年每年大約要出現(xiàn)１０００個左右的新詞新語，而字典、詞典的多次修訂、增補就反映了這種情況。但相對來說，也有一些流行語又逐漸受到冷遇，甚至退隱。為了更好的對新詞新語與流行文化作一番檢視與探究，那讓我們考察一下它們是怎么產(chǎn)生的吧？老師先給同學們列舉四種途徑：大屏幕３。同學們能再舉出以上途徑的一些例子嗎？老師列舉（４）其實不只這些，那還有哪些途徑呢？找同學說并舉例。說的非常好，請同學們看老師的例子，總結(jié)（５）。從新詞新語的產(chǎn)生途徑可以看出，這些鮮活得像畫一樣的新詞就是這個時代跳動的血小板，它涉及當代社會的重大事件、現(xiàn)象與時弊，以及人們?nèi)粘Ｉ畹母鱾€層面如人生意義、生活方式、愛情、友情、就業(yè)、消費、時尚等，時代性強，傳播面廣，反映著當代社會時局與人們文化心態(tài)的變化。
