五、教学Section B-2c1. Pair work: What do you think of the belt/sunglasses/…? What does your father/mother/… think of your scarf/belt…?2. Group work(1). Teacher shows some different kinds of school uniforms (制服)and asks : “ What do you think of your school uniforms? If you have a chance to choose your school uniforms, what kind would you like to choose?”(2). Discuss in groups.(3).Get some Ss to report in class.说明:这一步旨在让学生运用已有的语言知识谈论对事物的看法和意见,并简单阐明理由,培养学生的主动思维能力和运用英语的能力。六、教学拓展调查电视节目的收视率任务:调查你周围的人对现在各种电视节目的反响。活动过程:1.教师布置任务,让学生调查周围的人(包括他的亲戚朋友和邻居)喜欢收看哪方面的电视节目。2.学生进行调查活动,运用本单元所学的句型What do you think of….? (Why?)What's your favorite game shows?What do you think of talk show?I doesn’t mind it.I like it.I love it.I can’t stand it.3.记录下排在前10位的TV Program,填写调查表,比较其收视率。

《朝天子·咏喇叭》:这篇散曲借咏喇叭,讽刺和揭露了明代宦官作威作福、鱼肉百姓的罪恶行径,表达了对宦官专横跋扈、趾高气扬嘴脸的强烈憎恶之情。(2)根据上面的分析,适当运用轻重音、升降调等朗读技巧,有感情地反复朗读。(3)这几首诗词曲中,你最喜欢哪几句?说说你喜欢的理由,而后有感情地诵读。预设 【示例一】我喜欢“山河千古在,城郭一时非”。这两句以祖国山河万世永存与城郭一时沦陷进行对比,突出诗人对收复大宋江山的信念和对元人的蔑视。【示例二】我喜欢“无限山河泪,谁言天地宽”。从这两句我感受到了作者的满腔悲愤。作者一直盼望明王朝东山再起,可时运不济,命运多舛,恢复国土、重整山河的宏愿一次次落空,令作者感到深深的失望。【示例三】我喜欢“赢,都变做了土;输,都变做了土”。这两句揭示了深刻的道理,意为国家间无论怎样争斗,终究会在历史的长河中渐渐湮灭,在无尽的沧桑中被遗忘,化为沉寂的黄土。经过前面的诵读、品读环节,学生们对这几首诗词已经有了了解,再安排学生背诵,可以使学生印象更深。
由扶到放,学习课文 1.指导学习一至三段。 (1)指名读第一段。学习生字"弯、直",通过做动作理解词义。 (2)练习朗读第一段,可边读边做动作。 (3)教师引读第二段:小燕子从他头上飞过。小白兔大声喊--(学生读)。 (4)引导学生看第一幅挂图:小燕子飞得很低,小白兔奇怪地向燕子为什么飞得这么低。学生练习朗读小白兔喊叫的句子,提醒学生注意提示语"大声喊"和句尾问号。 (5)先指名读第三段,然后逐句以问引读: ① 教师指第一句问:燕子边飞边说-- ②空气怎么样呢--(学生接读第二句)虫子的翅膀可比鸟的翅膀小多了,薄多了,就像透明的纱一样,沾上了小水珠,就像人背上了铅球一样沉重,自然就飞不高了。再读第二句。 ③那小燕子飞不高是什么原因呢?学生读最后一句,教师板书:捉虫子,学习生字"捉",练习朗读句子。 (6)朗读第三段。
朗读背诵,感悟课文 1、你从什么地方知道柳树醒了?分小组交流交流。 (根据学生的回答依次学习相应小节。) 2、学生在读书交流中,随机出示课件中相应小节,帮助领悟,读好“醒、软、绿、飞、高”等词。 第一节:(课件出示:天空春雷一声响,地下一棵棵柳树摇了摇身子。) 想象:春雷会跟柳树说什么? 第二节:(课件出示:春雨沙沙,柳枝渐渐吐绿,向下垂。) 你觉得这一小节该怎样读呢? 第三节:(课件出示:春风吹动柳枝,柳枝飘荡) 引读,你们瞧!春风给柳树梳头,梳着梳着——(生读)。 第四节:谁想读第四节?谁知道“小柳絮”是什么样儿的?理解“柳絮”:(课件出示:一双燕子在空中飞来飞去,柳树上沾满上面结满有白色绒毛的种子,绒毛随风飞散。) 第五小节:(课件出示:柳树枝条在风中飘荡,孩子们在树下玩耍。)看,小柳树醒了,它在干什么?会班齐读。 3、再读读课文,想想:你从哪里知道“柳树醒了”?“柳树醒了”说明什么? 4、和同桌小伙伴一起试着背背课文,比比谁先会背。(课件出示课文插图,同时配乐。)
朗读(多层次自主阅读,拓展思维空间,提高阅读质量。) 1、检查读。教师以开火车的形式让学生按自然段读课文,看谁读得既正确又流利。 2、指正读。把你喜欢的小动物的话找出来读一读,教师随机指导。 3、想象读。先听范读录音,然后指名读文,边读边想象当时的情景。 4、分角色读。教师指导学生研究讨论每个角色的语气怎样读,并尝试给这些角色设计表情动作。 如:睡莲姑姑(奇怪的问):“小蚂蚁,你怎么了?” 小蚂蚁(揉肉眼睛,伤心的)说:“我不小心掉进池塘,上不了岸啦!” (让学生尝试添加提示语,是一个大胆的尝试。让学生根据生活经验和对课文的理解,给“人物”设计表情动作,添加不同的语气词,使课文变成了童话剧。由于是自己创造的成果,学生会读得有情有趣,有滋有味。但这种能力的培养不是一朝一夕的,教师要有意识的加以引导。)

煤的价格为400元/吨,生产1吨甲产品除需原料费用外,还需其他费用400元,甲产品每吨售价4600元;生产1吨乙产品除原料费用外,还需其他费用500元,乙产品每吨售价5500元.现将该矿石原料全部用完,设生产甲产品x吨,乙产品m吨,公司获得的总利润为y元.(1)写出m与x的关系式;(2)写出y与x的函数关系式.(不要求写自变量的取值范围)解析:(1)因为矿石的总量一定,当生产的甲产品的数量x变化时,那么乙产品的产量m将随之变化,m和x是动态变化的两个量;(2)题目中的等量关系为总利润y=甲产品的利润+乙产品的利润.解:(1)因为4m+10x=300,所以m=150-5x2.(2)生产1吨甲产品获利为4600-10×200-4×400-400=600(元);生产1吨乙产品获利为5500-4×200-8×400-500=1000(元).所以y=600x+1000m.将m=150-5x2代入,得y=600x+1000×150-5x2,即y=-1900x+75000.方法总结:根据条件求一次函数的关系式时,要找准题中所给的等量关系,然后求解.
