区分宾语从句、定于从句和状语从句宾语从句和状语从句,都叫做主从复合句。宾语从句主要是中考必考的,是初中阶段必掌握的从句,宾语从句主要是掌握三要素,所谓宾语从句,就是宾语在主从复合句当中充当宾语的一个句子,叫做宾语从句。主句的谓语动词是及物动词,后面如果是词或者是短语的话,是简单句,如果是句子的话,肯定是宾语从句。I know that he good at English.就是宾语从句,三要素,一要素是要注意连词,连词一共学了三类连词,一类连词是that口语当中可以省略,就像刚才说的那一句,I hear he is good at English.还有疑问代词、疑问副词,how where when,疑问代词、疑问副词。还有一类连词weather是否的意思,不是状语从句当中的如果,这一定要和如果区分开,这是是否。I don't know if he interested at English。宾语从句要注意if是连词。第二要素是语序,要用陈述举语序。比如说你家有几口人,我们都说How many people are there in you family?但是这是简单句,一旦说成宾语从句,你可以告诉我你家有几口人吗?Could you tell me how many people there are in you family ?
"Hello! Welcome to English class! Introduce yourself. Meet your new classmates." That's what the teacher says. What do you say? "Oh no!" It can be difficult talking to new people. But it can be fun, and you can make friends. How do you do it? Make small talk. Small talk is polite conversation. "Wang Nan is a great pingpang player, isn't she?" "I'd love to meet her, wouldn't you?" "It's been raining a lot, hasn't it?" Tag questions are a form of polite speech. To make small talk successfully, you should know how to make them. You should also know what topics to talk about. Try to learn this unit carefully. The next time you're in English class, you'll find out. Making small talk's easy, isn't it? (“你好!欢迎你!请做一下自我介绍。认识一下你的新同学。”通常在课上老师会这样说。你会说什么呢?“噢,不!”与陌生人谈话太困难了。但是这也很有意思,并且你还能交到朋友。你该怎么做呢?闲聊。闲聊指得是礼貌的对话。“王楠是一个很棒的乒乓球运动员,不是吗?”“我希望自己能认识她,你呢?“今年的雨水很多,不是吗?”反意疑问句是一种礼貌用语。为了使得谈话成功,你应该知道怎样去进行闲聊。你还应该知道与不同的人该谈论什么样的话题。认真的学习这个单元吧,下次在英语课上,你会发现与大家展开谈话是一件很容易的事情,不信我们来试试。)

我荣幸地以中华民族一员的资格,而成为世界公民。我是中国人民的儿子。我深情地爱着我的祖国和人民。 ——邓小平一个人只要热爱自己的祖国,有一颗爱国之心,就什么事情都能解决。什么苦楚,什么冤屈都受得了。 ——冰心做人最大的事情是什么呢?就是要知道怎么样爱国。 ——孙中山能够献身于自己祖国的事业,为实现理想而斗争,这是最光荣不过的事情了。——吴玉章外国爱国名言示例:我们为祖国服务,也不能都采用同一方式,每个人应该按照资禀,各尽所能。——歌德纵使世界给我珍宝和荣誉,我也不愿离开我的祖国。因为纵使我的祖国在耻辱之中,我还是喜欢、热爱、祝福我的祖国。 ——裴多菲我重视祖国的利益,甚于自己的生命和我所珍爱的儿女。 ——莎士比亚我无论做什么,始终在想着,只要我的精力允许我的话,我就要首先为我的祖国服务。 ——巴甫洛夫
本环节旨在通过展示、评价践行“孝亲敬老”的活动成果,深化 “孝”的境界,培养学生回报家人、关爱他人的美德。展示过程中,学生的语言表达能力、诵读能力、搜集和整理资料的能力、写作能力得到了提升,同时也增强了自信心。二、谈“孝”心1.在这为期一周的践行“孝”的活动中,你有哪些体会和感受?请与大家分享。(生小组内交流,小组代表发言)预设 示例一:在这次践行“孝”的活动中,我做了许多表达孝心的事情,从中体会到了父母工作的艰辛、赚钱的不易,更能体谅他们了。我也了解到平时我不经意说的话伤害了父母,让父母担忧难过了。现在我与父母之间的关系变得更加融洽,父母对我的一些事情也能够理解了,我发现只要我们对父母多一些尊重和理解,他们就会非常开心。示例二:我在采访爷爷奶奶时,了解到祖辈们的人生经历和具体事迹,被他们身上的一些精神品质所感动,更加钦佩他们了。这次的采访活动增强了我与家人之间的沟通,增进了我与家人之间的情感交流,也让我进一步了解了我们家族的一些历史,让我有了为家族努力奋斗的使命感。
一是缩小页边距和行间距,缩小字号。正式文件一般对字号、间距有严格的要求,但是在非正式文件里,可适当缩小页边距和行间距,缩小字号。可“上顶天,下连地,两边够齐”,对于字号,以看清为宜。二是纸张双面打印、复印。纸张双面打印、复印既可以减少费用,又可以节能减排。如果全国10%的打印、复印做到这一点,那么每年可减少耗纸约5.1万吨,节能6.4万吨标准煤,相应减排二氧化碳16.4万吨。三是打印时能不加粗、不用黑体的就尽量不用,能节省墨粉或铅粉。此外,能够用电脑网络传递的文件就尽量在网络上传递,比如电子邮件、单位内部网络等,这样下来也可以节约不少纸张。(选自《低碳校园——让我们的学校更美好》,天津人民出版社2013年版)(学生围绕各自任务,课外搜集制作宣传材料,时间为一周。)【设计意图】本环节先从探讨自身在低碳生活中力所能及的事情,让学生切实认识到低碳生活就在日常的一举一动中。然后围绕主题分组,并保证足够的时间,让学生去收集整理资料,落实任务,使学生能真正成为低碳的倡导者和践行者。
解说词:画卷上的竹子,在石缝中挺然而立,坚韧不拔,遇风不倒。郑板桥先生借竹抒发了自己的洒脱与豁达,表现了他勇敢面对现实、绝不屈服于挫折的品性,令竹子人格化了。此时,“诗是无形画,画是有形诗”。4.声情并茂诵古诗(播放相关的主题图片和音乐,尽量让诗歌和音乐、画面相融合)主持人:诗除了追求意境的图画美之外,还特别注重节奏和韵律,具有音乐美。我们理解了诗中的情愫后,便可以通过朗读来诠释这种种情愫,或低声絮语,或慷慨悲吟,或温情述说……请大家选择自己最喜欢的一首诗词或一小节诗歌,用你认为最贴切的情感和方式朗读,并说出这样处理的原因,或讲述你与此诗有关的故事。朗读示例:无言/独上西楼,月/如钩,寂寞梧桐/深院/锁/清秋。剪不断,理还乱,是离愁,别是/一般滋味/在心头。解说词:此词是南唐后主李煜被囚于宋时所作,表达了他离乡去国的锥心之痛。朗读时要表现出那种深切的故国之思、亡国之恨。
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(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。)
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。)
方程有两个不相等的实数根.综上所述,m=3.易错提醒:本题由根与系数的关系求出字母m的值,但一定要代入判别式验算,字母m的取值必须使判别式大于0,这一点很容易被忽略.三、板书设计一元二次方程的根与系数的关系关系:如果方程ax2+bx+c=0(a≠0) 有两个实数根x1,x2,那么x1+x2 =-ba,x1x2=ca应用利用根与系数的关系求代数式的值已知方程一根,利用根与系数的关系求方程的另一根判别式及根与系数的关系的综合应用让学生经历探索,尝试发现韦达定理,感受不完全的归纳验证以及演绎证明.通过观察、实践、讨论等活动,经历发现问题、发现关系的过程,养成独立思考的习惯,培养学生观察、分析和综合判断的能力,激发学生发现规律的积极性,激励学生勇于探索的精神.通过交流互动,逐步养成合作的意识及严谨的治学精神.
3、一般地,对于关于 方程 为已知常数, ,试用求根公式求出它的两个解x1、x2,算一算x1+x2、x1?x2的值,你能得出什么结果?与上面发现的现象是否一致。【知识应用】 1、(1)不解方程,求方程两根的和两根的积:① ② (2)已知方程 的一个根是2,求它的另一个根及 的值。(3)不解方程,求一 元二次方程 两个根的①平方和;②倒数和。(4)求一元二次方程,使它的两个根是 。【归纳小结】【作业】1、已知方程 的一个根是1,求它的另一个根及 的值。2、设 是方程 的两个根,不解方程,求下列各式的值。① ;② 3、求一个一元次方程,使它的两 个根分别为:① ;② 4、下列方程两根的和与两根的积各是多少 ?① ; ② ; ③ ; ④ ;
