    人教版高中语文必修2《氓》教案2篇

    从《诗经》的现实主义到屈原的浪漫主义,是中国诗歌发展的一个里程碑。屈原的骚体诗,依诗取兴,引类譬喻,继承发展了《诗经》的比兴传统。《诗经》的比兴较为单纯,而《楚辞》的比兴具有象征的特质,往往成为一个形象的系统。《离骚》中香草美人的比兴就是范例。楚地本是泽乡山国,其间颇有叠波旷宇、崇山秀岭,这些江山的光怪之气足以摇荡心灵、催发丽辞伟句。但骚体诗已冲破《诗经》四言诗的固定格式,句式加长而灵活,篇章放大而严密,诗采绚丽而贴切,是《诗经》之后的一次诗体大解放。有人说,中国历代诗“莫不同祖风骚”,足见其对后代诗歌的影响。先秦时代,《诗经》与《楚辞》双峰并峙,是中国诗史上现实主义与浪漫主义的两座巍然屹立的坐标。

    人教版高中语文必修2《游褒禅山记》教案2篇

    1.本文由“不得极夫游之乐”生发出“尽吾志”的观点,又由“仆碑”生发出“深思慎取”的观点,这两个观点彼此有联系吗?作者游褒禅山,本来是一次平常的游历活动,但却从中悟出了人生哲理──从前洞后洞游人的多少悟出“夷以近,则游者众;险以远,则至者少”,从“入之愈深,其进愈难,而其见愈奇”悟出“而世之奇伟、瑰怪、非常之观,常在于险远”;由此再引申一步,就得出了“非有志者不能至”的结论。然后将这次游山而未能“极夫游之乐”的教训升华到理论上来,具体分析了“至”的几个条件,最后得出“尽吾志”的观点──这正是“求思之深而无不在”的结果。由此可见,“尽吾志”的观点跟“深思慎取”的观点是有联系的:“尽吾志”的观点是在“深思慎取”的基础上产生的;有了这个观点,又能反过来促使人们“深思慎取”,二者是相辅相成的。

    人教版高中语文必修2《家》教案3篇

    (幻灯六)巴金作品《家》描写的是“五四”之后,成都地区一个封建大家庭走向崩溃的故事。故事集中在1920年冬到1921年秋的八九个月时间里。成都的一个官僚地主家庭高公馆,一家之主的高老太爷,封建专制,顽固不化。长房长孙觉新,为人厚道,却很软弱,原与梅表姐相爱,后屈从于老太爷之命而与李瑞珏结婚。后来梅和瑞珏双双惨死。觉新的胞弟觉民、觉慧积极参加爱国运动,从而和冯公馆的冯乐山成了死对头。觉民爱上琴,冯乐山却要他娶自己的侄孙女,在觉民觉慧的反抗下,他们终于取得胜利。觉慧爱上聪明伶俐的婢女鸣凤,但冯乐山却指名要娶鸣凤为妾,鸣凤坚决不从,投湖自尽…至此,觉新有所觉醒,而觉慧则毅然脱离家庭,投身革命。(故事主要以高家三兄弟的爱情遭际为线索。)

    人教版高中语文必修3《锦瑟》教案2篇

    【参考】“沧海月明珠有泪,蓝田日暖玉生烟。”沧海中的珍珠只有在明月之夜,才能流下晶莹的泪花;蓝田下的美玉只有在日暖之时,才能升腾飘逸的烟霞。物犹如此,人当如是。“沧海月明”与“蓝田日暖”优美意境的创设,不仅仅是诗人精妙绝伦艺术素养的表现和挥洒,更是诗人回答人生价值的标准和尺度。诗人以物推人,拓展深化了诗作的主题,整篇的闪光点在此,魂亦在此。【参考】“此情可待成追忆,只是当时已惘然。”追忆过去,尽管自己以一颗浸满血泪的真诚之心,付出巨大的努力,去追求美好的人生理想,可“五十弦”如玉的岁月、如珠的年华,值得珍惜之时却等闲而过;面对现实:恋人生离、爱妻死别、盛年已逝、抱负难展、功业未建……,幡醒悟之日已风光不再。如泣如诉的悲剧式结问,又让诗人重新回到对“人生价值到底是什么?到底该怎样实现?”深深的思考和迷惑之中,大大增强了诗作的震撼力。

    2、黛玉进入贾府到贾母处,她看到了什么?提示:从荣府西角门进去,走“一射之地”,转至垂花门,过穿堂,绕插屏,再经三间过厅,后面方是贾母居住的正房大院。“正面五间上房,皆雕梁画栋,两边穿山游廊厢房,挂着各色鹦鹉、画眉等鸟雀。”这样穿堂过厅一路行来,仆役、婆子、丫环轮番更换,的确给人以侯门深似海的感觉。然而贾母居处还不是正内室。3、黛玉去拜见二舅舅时又看到什么?提示:往东。“穿过一个东西的穿堂,向南大厅之后,仪门内大院落,上面五间大正房,两边厢房鹿顶耳房钻山,四通八达,轩昂壮丽”。堂屋中迎面“一个赤金九龙青地大匾,匾上写着斗大的三个大字,是‘荣禧堂’,后有一行小字:‘某年月日,书赐荣国公贾源’,又有‘万几宸翰之宝’。”屋内摆设有名贵的家具,珍贵的字画、古玩。“又有一副对联,乃乌木联牌,镶着錾银的字迹,道是:座上珠讥昭日月,堂前黼黻焕烟霞。”由堂屋进入东耳房,这里是起居室,另有一番布置,再到东廊三间小正房王夫人的住室,又别有摆设。

  • 新人教版高中英语必修3Unit 1 Festivals and Celebrations-Listening &Speaking&Talking教学设计

    新人教版高中英语必修3Unit 1 Festivals and Celebrations-Listening &Speaking&Talking教学设计

    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.

    The themes of this part are “Talk about how to become an astronaut” and “Talk about life in space”. As Neil Armstrong said “Mystery creates wonder and wonder is the basis of man’s desire to understand. Space is difficult for human to reach, therefore, humans are full of wonders about it. However, if wanting to achieve the dream of reaching the Moon, some of our human should work hard to be an astronaut at first. Part A(Talk about how to become an astronaut) is a radio interview in a radio studio, where the host asked the Chinese astronauts about his story how to become an astronaut. Yang Liwei told his dreamed to be an astronaut since childhood. Then he worked hard to get into college at 22. The next 10 years, he gradually became an experienced pilot. At the same time, to be an astronaut, he had to study hard English, science and astronomy and trained hard to keep in good physical and mental health and to practise using space equipment. Part B (Talk about life in space) is also an interview with the astronaut Brown, who is back on the earth.
