A: What are you most keen on?? B: I've really become keen on learning more about the Chinese culture, in particular Chinese calligraphy. As I have learnt Chinese characters, I have developed a great appreciation for their meaning. I want to explore Chinese characters by learning how to write them in a more beautiful way. ? A: Finally, what do you want to say to anyone interested in learning Chinese?? I have really become keen on learning more about the Chinese culture, in particular Chinese Calligraphy. As I have learnt Chinese character, I have developed a great appreciation for their meaning. I want to explore Chinese characters by learning how to write them in a more beautiful way.? A: Finally, what do you want to say to anyone interested in learning Chinese?? B: I'd say, give it a shot! While some aspects may be difficult, it is quite rewarding and you will be happy that you tried.? A: Thanks for your time. ? B:You're welcome.
This section guides students to pay attention to the typical context of vocabulary use, helps students accumulate vocabulary around the key vocabulary of this unit, and uses the learned words and word chunks in different contexts to deeply understand their meaning and usage, so as to achieve the purpose of review and consolidation.The teaching design activities aim to guide students to pay attention to the typical context in which the target vocabulary is used, as well as the common vocabulary used in collocation, so that students can complete the sentence with correct words. In terms of vocabulary learning strategies, this unit focuses on cultivating students' ability to pay attention to collocation of words and to use word blocks to express meaning.For vocabulary learning, it is not enough just to know the meaning of a single word, but the most important thing is to master the common collocations of words, namely word blocks.Teachers should timely guide students to summarize common vocabulary collocation, such as verb and noun collocation, verb and preposition collocation, preposition and noun collocation, and so on.1. Guide students to understand and consolidate the meaning and usage of the vocabulary in the context, 2. Guide the students to use the unit topic vocabulary in a richer context3. Let the students sort out and accumulate the accumulated vocabulary, establishes the semantic connection between the vocabulary,4. Enable students to understand and master the vocabulary more effectivelyGuiding the Ss to use unit topic words and the sentence patterns in a richer context.

【设计意图】本环节意在指导学生做好新闻采访前的准备工作。草拟新闻采访提纲,是进行新闻采访的关键环节。学生只有做好了采访前的准备工作,才能在采访过程中有的放矢,不慌不忙。五、采访实践,检验学习所得四人一个小组设计采访活动,选定采访对象,制订采访提纲进行现场采访。师点拨:采访时要注意当场做笔记,采访后要注意及时整理。整理注意点:1.整理要及时。采访一结束,就要在“记忆的黄金时段”立刻整理记录。2.整理材料应去粗存精,选择重点。整理过程中还要疏通文字,进一步补充、核实材料。3.充分发挥笔记的作用,积累新材料,写好新闻稿。结束语:这节课我们学习了新闻采访的相关知识,大家要重点掌握采访的流程与注意事项,希望通过这节课的学习能激起大家对采访的兴趣,也希望通过本节课的学习,同学们在口语表达能力上可以有一个很大的提升,也许在不远的将来,你就是一名出色的记者。
一、情境导学我国著名数学家吴文俊先生在《数学教育现代化问题》中指出:“数学研究数量关系与空间形式,简单讲就是形与数,欧几里得几何体系的特点是排除了数量关系,对于研究空间形式,你要真正的‘腾飞’,不通过数量关系,我想不出有什么好的办法…….”吴文俊先生明确地指出中学几何的“腾飞”是“数量化”,也就是坐标系的引入,使得几何问题“代数化”,为了使得空间几何“代数化”,我们引入了坐标及其运算.二、探究新知一、空间直角坐标系与坐标表示1.空间直角坐标系在空间选定一点O和一个单位正交基底{i,j,k},以点O为原点,分别以i,j,k的方向为正方向、以它们的长为单位长度建立三条数轴:x轴、y轴、z轴,它们都叫做坐标轴.这时我们就建立了一个空间直角坐标系Oxyz,O叫做原点,i,j,k都叫做坐标向量,通过每两个坐标轴的平面叫做坐标平面,分别称为Oxy平面,Oyz平面,Ozx平面.
本节课选自《2019人教A版高中数学选择性必修第一册》第二章《直线和圆的方程》,本节课主要学习抛物线及其标准方程在经历了椭圆和双曲线的学习后再学习抛物线,是在学生原有认知的基础上从几何与代数两 个角度去认识抛物线.教材在抛物线的定义这个内容的安排上是:先从直观上认识抛物线,再从画法中提炼出抛物线的几何特征,由此抽象概括出抛物线的定义,最后是抛物线定义的简单应用.这样的安排不仅体现出《课程标准》中要求通过丰富的实例展开教学的理念,而且符合学生从具体到抽象的认知规律,有利于学生对概念的学习和理解.坐标法的教学贯穿了整个“圆锥曲线方程”一章,是学生应重点掌握的基本数学方法 运动变化和对立统一的思想观点在这节知识中得到了突出体现,我们必须充分利用好这部分教材进行教学
∵在△EFP中,|EF|=2c,EF上的高为点P的纵坐标,∴S△EFP=4/3c2=12,∴c=3,即P点坐标为(5,4).由两点间的距离公式|PE|=√("(" 5+3")" ^2+4^2 )=4√5,|PF|=√("(" 5"-" 3")" ^2+4^2 )=2√5,∴a=√5.又b2=c2-a2=4,故所求双曲线的方程为x^2/5-y^2/4=1.5.求适合下列条件的双曲线的标准方程.(1)两个焦点的坐标分别是(-5,0),(5,0),双曲线上的点与两焦点的距离之差的绝对值等于8;(2)以椭圆x^2/8+y^2/5=1长轴的端点为焦点,且经过点(3,√10);(3)a=b,经过点(3,-1).解:(1)由双曲线的定义知,2a=8,所以a=4,又知焦点在x轴上,且c=5,所以b2=c2-a2=25-16=9,所以双曲线的标准方程为x^2/16-y^2/9=1.(2)由题意得,双曲线的焦点在x轴上,且c=2√2.设双曲线的标准方程为x^2/a^2 -y^2/b^2 =1(a>0,b>0),则有a2+b2=c2=8,9/a^2 -10/b^2 =1,解得a2=3,b2=5.故所求双曲线的标准方程为x^2/3-y^2/5=1.(3)当焦点在x轴上时,可设双曲线方程为x2-y2=a2,将点(3,-1)代入,得32-(-1)2=a2,所以a2=b2=8.因此,所求的双曲线的标准方程为x^2/8-y^2/8=1.当焦点在y轴上时,可设双曲线方程为y2-x2=a2,将点(3,-1)代入,得(-1)2-32=a2,a2=-8,不可能,所以焦点不可能在y轴上.综上,所求双曲线的标准方程为x^2/8-y^2/8=1.
材料五航路开辟后,东方香料输入欧洲的总量较中古之时猛增30倍,而胡椒、丁香等在印度购入和在英国卖出的差价亦高达10至29倍,其他货物的获利同样惊人。这一时期,新的商品不断涌现,特别值得注意的是美洲的特产——玉米、马铃薯、烟草、可可等——被传播到欧亚大陆。这时,世界性的对外贸易主要通过大西洋,地中海与意大利皆告衰落,而沿大洋的英、荷等渐居中心。到17世纪时,英国的伦敦与荷兰的阿姆斯特丹成为世界贸易中心。问题4:材料五表明,新航路开辟后对世界贸易产生了哪些重大影响?答案4:结束了世界相对孤立状态;各地文明开始会合交流,日益连成一个整体;欧洲商人直接同世界各地建立商业联系;促进不同国家和贸易的发展,促进世界市场雏形开始出现。
【教学参考】对“新政”作用的评价史学界对“新政”作用的评价是仁者见仁、智者见智,但基本上有三种观点,即“功大于过论”、“过大于功论”和“功过参半论”。持“功大于过论”者认为“新政”在美国历史上基本上是一种进步现象,首先,“新政”挽救了危机,使美国人民摆脱了危机的困苦局面;其次,在缺少足够的宏观经济政策知识的时代,罗斯福所做的努力确实是开创性的;再次,罗斯福“新政”开启了美国以后历届政府实施国家干预政策的大门,成为缓解自由主义经济制度之弊病的一剂良方,并在实质上加强了美国联邦政府的权威;最后,在30年代资本主义世界经济危机的背景下,同日本、德国为转嫁危机而发动战争的策略相比,“新政”无疑代表了一种进步、民主的解救危机方式。持“过大于功论”者认为“新政”未能使美国走出萧条、步入繁荣。
老师们、同学们,大家新年好!伴随着雄壮的义勇军进行曲,鲜艳的五星红旗再次在我们眼前冉冉升起,一个充满希望的新学期已经开始了。大家刚刚经过了一个愉快而有意义的寒假,度过了一个非常值得回味的新春佳节。回首刚刚过去的一年,全体同学勤奋好学,全体教职工严谨教学。过去的一年我们全体竹中人齐心协力、勤奋学习、扎实工作,学校获得了很好的发展,同学们取得了不错的成绩。XX年高考我校再创辉煌,大批同学被高校录取,在上学期期中、期末考试中我校成绩表现良好。全体教师的专业素养得到了很好的发展和提升,在溧阳市第九批“四类优秀教师”评选中,我校有24位老师被评为“四类优秀教师”,在学科基本功竞赛和优秀课评比中,我校有10多位老师获等级奖,同时学校也承担了10多次市级学科教研活动和校际教研活动,2次学科理事会年会活动。同时,学生的特长和能力也得到了很好的彰显,在参加江苏省第十五届作文大赛中,有35位同学获奖。在初中英语口语比赛中有3位同学分别获一等奖和三等奖。在八年级“古诗文创作”比赛中有2位同学获奖,同时有不少同学被评为省、市、校级“三好学生”、“优秀学生干部”。等等。
老师们、同学们:过年好,今天我们全体师生又一次集合在国旗下,这是我们全体师生16年的第一次聚会,它预示着我们新的学习和工作生活的开始。一年之计在于春,一日之计在于晨,希望我们全体xx中学人抓住春天的希望,规划好自己一学期的发展;更希望我们xx中学人珍惜每一个早晨,踏踏实实的过好每一天。相信在我们每一位师生的共同努力下,我们每一天都会与收获,每一周都会有积累,每一月都会有进步,每一学期都会有突破的喜悦。今天,我借用别的校长的发言来作为我今天第一次国旗下的内容,以期与老师们、同学们共勉!他的主题是《不读书、不吃苦,你要青春干嘛》短暂的寒假结束了,新的学期开始了。回忆十来天的假期,你是否有值得回味的事情和经历呢?我想,不同的人肯定有不同的收获和感受。有的同学“收获”的胡吃海睡,做的是“低头追剧”一族,并且生活的节奏全部被打乱——该睡的时候不睡,该起的时候不起,该吃的时候不吃;而有的同学选择了认真完成寒假作业之余适当放松;有的同学选择了放下包袱,在旅途中放松身心,增长见识;也有的同学撇开喧嚣纷扰,选择了一本好书,与伟大的心灵对话,让自己的精神旅行;有的同学会利用丰富的网络资源来强化自己的薄弱学科,实现弯道超越;还有的同学会和自己的良师益友促膝谈心,获取前进的动力,感悟人生的真谛!规划不同,过法不同,寒假对于我们的意义就不同。有的同学可能难以理解,假期有必要这么拼,这么苦,这么累吗?我的回答是大有必要。这就是今天我要告诉大家的,怕吃苦,苦一辈子,不怕苦,苦一阵子。
2.把握朗读节奏。示例:舜/发于/畎亩之中,傅说/举于/版筑之间,胶鬲/举于/鱼盐之中,管夷吾/举于/士,孙叔敖/举于/海,百里奚/举于/市。故/天将降大任/于是人也,必先/苦/其心志,劳/其筋骨,饿/其体肤,空乏/其身,行/拂/乱/其所为,所以/动心/忍性,曾益/其所不能。3.反复朗读,并结合课文注释,感知文义。4.教师引导梳理文章大意,梳理文言现象。【通假字】曾益其所不能(曾,同“增”,增加)衡于虑(衡,同“横”,梗塞、不顺)入则无法家拂士(拂,同“弼”,辅佐)【使动用法】必先苦其心志(使……痛苦)劳其筋骨(使……劳累)饿其体肤(使……饥饿)目标导学二:把握论点,理清论证思路1.文章开头列举了六个人物,他们的共同点是什么?明确:他们的共同点:都出身卑微,历经苦难磨炼,最终都被提拔任用,有所作为。
一、导入新课有这样一个人,他少有大志,以管仲、晏婴等名相自期,想辅佐帝王,成就伟业,“使寰区大定,海县清一”。即使退而求其次,也要像他的乡人司马相如、扬雄那样,以一篇辞赋文章一鸣惊人,为天子所用。他二十四岁离开蜀地,“仗剑去国,辞亲远游”,漂泊大半生,直到四十二岁才奉诏供奉翰林,两年以后又不容于朝,被迫出京。这个人就是李白。今天我们来学习他的代表作《行路难》(其一),感受诗人李白的浪漫主义风格。二、教学新课目标导学一:认识作者,了解写作背景作者简介:李白,字太白,号青莲居士。中国唐朝诗人,有“诗仙”之称。年轻时漫游全国各地,曾经至长安,供奉翰林,但不久遭谗去职。晚年漂泊东南一带,最后病死于当涂。其诗多强烈抨击当时的黑暗现实,深切关怀时局安危,热爱祖国山河,同情下层人民,鄙夷世俗,蔑视权贵;但也往往流露出一些饮酒求仙、放纵享乐的消极思想。他善于从民间吸取营养,想象丰富奇特,风格雄健奔放,色调瑰奇绚丽,是中国文学史上继屈原之后伟大的浪漫主义诗人。
【教学提示】引导学生分析把握人物的性格特征,在理清人物性格之后,可分角色扮演,还原三顾茅庐情景。角色表演时注意引导学生表现出角色的独特性格。目标导学四:精彩段落研读,解说“隆中对”内容精读“又立了一个时辰,孔明才醒……以成鼎足之势,然后可图中原也”,完成以下问题。1.请你结合全文内容,说一说你对诸葛亮所吟的四句诗的理解。明确:“大梦谁先觉?平生我自知”暗示诸葛亮“未出茅庐,已知三分天下”的雄才大略,“草堂春睡足,窗外日迟迟”写出了诸葛亮淡泊名利。这四句诗为下文故事情节的发展做了铺垫。2.为什么作者安排通过刘备的视线写诸葛亮的相貌?相貌描写片段:玄德见孔明身长八尺,面如冠玉,头戴纶巾,身披鹤氅,飘飘然有神仙之概。明确:一方面写出诸葛亮气宇轩昂,神异不凡,另一方面更加坚定了刘备对诸葛亮的信任,确实有将相之才,又为下文的一再邀请做了铺垫。
分析是联系论据与论点的桥梁,是丰富文章内容的关键所在。有了分析,事例和论点就能成为有机的统一体;只有通过理性的分析,剖析出事例与论点之间的关系,才能让文章拥有令人信服的逻辑力量。总结:运用论据的时候,对论据进行适当的变化、概括、分析,要有重点、有意识地突出所述事实论据和观点一致的地方,保证所述事实与观点相对应。可参照“分论点+事例+对事例进行分析+结论(照应分论点)”这样的格式来进行论证。【设计意图】以学生小组讨论来得出运用论据的三个方法 ,让学生自己在交流讨论中品味体验。通过“讨论”“交流”等形式实现学生的自主学习,达到培养学生独立思考能力和写作表达能力的目的。五、品读例文,评点“言之有据”1.根据文题,画思维导图课件出示:《论语·为政》中说:“人而无信,不知其可也。”诚信,自古以来就是一种美德。欺诈、造假等不讲诚信的现象历来为人们所深恶痛绝。请以《谈诚信》为题,尝试画一个议论文的思维导图。
三、实战演练1.明确题干要求师:阅读教材P18的写作实践三,读读题干和“提示”,然后集中讨论一下,你是如何理解这个写作实践暗含的要求的。预设(1)这个题目可以简单概括为成长中的事件,范围比较宽广,类似于经常碰到的《难忘的一件事》一类的作文题。(2)一定要注意“成长”这个关键词,在描述这个事件时,一定要写出自己人生体悟的变化。(3)要选择一件有意义的、使“我”成长的事来写,在文末还应升华主题,写出自己在经历这件事后得到的人生启示。2.补充写作提示师:为了帮助大家完成好这次习作,老师在教材的基础上,还另外补充了三条“提示”。课件出示:提示:1.选材要小。选取生活中的一两个片段来刻画人物、表达感情。从小事入手,于细微处见精神,以小见大,突出“难忘”“印象深刻”。2.叙事要详略得当。叙事要围绕中心,抓住重点,把最能体现事件意义、最能展示人物形象的言行、心理描写得真实而详细。同时,要讲究剪裁,选取典型的、能揭示事物本质的、有说服力的材料表达中心思想,做到详略得当,主次分明。
预设 这篇邀请函格式正确、要素齐全、语言得体。主要表现在:标题直接点明邀请的目的,清晰醒目;格式上有称呼、问候语、祝颂语、落款,符合邀请函的基本格式要求;正文中有邀请的理由,让家长明确被邀请的原因;有活动的时间、地点,以及启动仪式的流程和注意事项,让被邀请者有所了解和准备,更显真诚、有礼。整个邀请函,态度诚恳,简洁明了,表达得体。3.拓展迁移,把握书信体应用文写作格式师:请同学们探讨一下,采用书信格式写作的应用文还有哪些?它们的共同点是什么?预设 感谢信、慰问信、表扬信、申请书(请假条)、倡议书、介绍信、证明信、求职信、应聘信、祝贺信、请柬等。格式一般由六个部分构成,即标题、称呼、问候语、正文、祝颂语、落款。
