When itcomes to a meaningful life, we might think of love, happiness and health. Alife filled with meaning is what most of us want for ourselves. Then, whatmakes a meaningful life?Manyresearchers agree that a meaningful life comes down to three factors (因素): havinglong-term goals, believing that one’s life matters, and feeling that one’s lifefits together and “makes sense”.But we believe there is more to consider. Sometimeslife enables us to experience small moments of beauty. When people are open toappreciating (欣赏) suchexperiences, these moments may improve how they see their own life. We callthis experiential appreciation (EA).

[教学目标]1.知识与技能:巩固 100 以内数的认识,进一步理解数位和位值的含义,发展学生有序的思维能力,以及培养他们的归纳能力。2.过程与方法:学生经历“摆一摆、想一想”的主动探索的学习过程,探索出100 以内数的特点及规律。3.情感、态度与价值观:在实践操作中,通过找规律来发展学生的初步抽象思维能力。[重点难点]1.教学重点:进一步理解数位和位值的含义,发展学生有序的思维能力,以及培养他们的归纳能力。2.教学难点:发展学生有序的思维能力。[教学准备] 课件、数位表、磁力扣、围棋子(每人3 颗)。[教学过程]一、激趣导入1.用 1 颗棋子摆数。师:今天,我给同学们请来了一位好朋友,你们看!课件演示:同学们,大家好!我是围棋宝宝,今天我来和大家一起学习,你们高兴吗?这是你们学过的数位表吧?我也来看看!(围棋子跳到个位上)你们知道我现在表示几吗?为什么?生:表示 1,因为个位上有 1 个。
1. 课前观看视频《物理学与人类文明》2. 分组讨论,派代表发言,谈学习感受。主要是物理的地位,物理的学习方法。3. 高中物理与初中物理在内容和方法上的区别高中物理除了现象、概念和规律之外还应该关注研究问题的方法,学会从先想到抽象,从定性到定量研究问题,学会用数学方法解决物理问题,学会实验探究,学会独立分析问题解决问题的思维习惯。4. 高中物理学习的基本要求高中物理学习应该“重视实验,勤于思考”和“经历过程,体验方法”。高中物理学习与初中物理学习虽然有一定区别,但也不是孤立的,要继续坚持初中物理学习中积累的学习方法和体会,重视从正反两个方面加以总结和提炼,做到:(1) 认真阅读,学会自学要学好物理,就要认真阅读课本。阅读课本是要抓住关键词语,弄清语句间的逻辑顺序和因果关系,领会文章段落所表达的物理内容,掌握课本叙述物理问题的表达方法。
八、物理学的基础地位及物理学对人类文明、社会进步的影响。(1) 情景一:磁悬浮实验:找两个空心的圆柱片磁铁,同名磁极相对,穿在同一根竹筷上,用手压下上面的磁铁,松手观察它的运动情况。问题1:上面的磁铁为什么会跳起来,为什么会悬浮在下面的磁铁上方?问题2:根据这个实验,你会想到那一种交通工具?总结:人们就是从磁悬浮现象中得到启发,进行磁悬浮列车的研究和制造的,这说明物理学在推动社会进步、人类文明方面起到推动作用。(2) 情景二:感应起电和火花放电实验:用感应起电机或感应圈产生火花放电,让学生观察现象,闻气味,然后联想生活实例。还可以用一张纸试着挡住放电的弧光,最好能引燃纸张,说明雷击引起火灾的现象。问题1:你看、听到了什么现象?问题2:根据这个实验,你会想到那一种自然现象?问题3:放电发生在什么地方?为什么建筑物上方都有尖尖的设置,是干什么用的?问题4:你闻到什么气味了吗?
少年兴则国兴,少年强则国强。你们从小要勤奋学习,锐意进取、自强不息、艰苦奋斗、顽强拼搏,真正把爱国之志变成报国之行,为创造祖国辉煌未来贡献自己的力量!关于祖国国旗下讲话稿 滔滔的江水,滚滚的黄河,连绵不断的山路,都属于我们伟大的祖国。祖国的山川雄奇,祖国的河水秀逸,祖国的胸怀无比广阔。当侵略者的铁碲践踏我们美丽山河的时候,每一个有良知的中国人脸上流着泪,心中淌着血。为了心中神圣不可侵犯的祖国,他们在黑暗中摸索,在屈辱中抗争。闻一多拍案而起,横眉冷对暗杀者的手枪;吉鸿昌高挂写有“我是中国人”标语的木牌,走在一片蓝眼睛、黄头发的洋人之中;张学良,杨虎城将军为了挽救民族危亡,毅然发动了西安事变……英雄长已矣!古往今来,一曲曲悲歌,一个个惊天动地泣鬼神的故事,都讲述一个简单而朴素的信念,祖国在我心中.正是这千千万万的赤子,才撑起了我们民族的脊梁,祖国的希望;正是他们,在自己的“今天”,用满腔的热血,谱写了无愧于时代的《义勇军进行曲》,才使得我们今天的共和国国歌响彻神州,那么气势磅礴,那么雄壮嘹亮。
②许多植物具有“慧眼”识光的能力,它们自知日出东山,夕阳西下,从而把握了自己开花和落叶的时间,如牵牛花天刚亮就开花,向日葵始终朝阳。植物不仅能“看见”光,还能感觉出光照的“数量”和质量,某些北方良种引种到南方,颗粒不收,就是因为植物的“眼睛”对异地的光线不习惯。植物的“眼睛”对光色也非常敏感,不同植物可识别不同光线,以促进自身的生长与发育。植物的“眼睛”原来是存在于细胞中的一种专门色素——视觉色素,植物凭借这种“眼睛”,从根到叶尖形成完整而灵敏的感光系统,对光产生既定反应,如花开、花合、叶子向左向右、变换根的生长方向等。 ③植物界中不仅有靠根吃“素”的植物,而且还有靠“口”吃“荤”的植物,食虫植物(也称食肉植物)便是这类植物。这些植物的叶子变得非常奇特,它们形成各种形状的“口”,有的像瓶子,有的像小口袋或蚌壳,能分泌消化昆虫的黏液,还能分泌香味,许多昆虫因为闻到香味,而跌入了陷阱之中!植物靠“口”捕食蚊蝇类的小虫子,有时也能“吃”掉像蜻蜒一样的大昆虫。它们分布于世界各地,种类有500多种,最著名的有瓶子草、猪笼草、狸藻等。
那是纽约州的午夜,她刚听完一场音乐会回来,从宿舍里打电话给我:“今天晚上,我们学校来了一个图瓦共和国的合唱团,他们唱的歌,我从前也听过,你每次去蒙古,带回来的录音带和CD里面都有。可是那个时候什么感觉也没有,为什么今天晚上他们在台上一开始唱,我的眼泪就一直不停地掉下来?好奇怪啊!我周围的同学都是西方人,他们也喜欢这个合唱团,直说歌声真美,可是,为什么我会觉得那歌声除了美以外,还有一种好像只有我才能了解的孤独和寂寞,觉得离他们好近、好亲。整个晚上,我都在想,原来妈妈的眼泪就是这样流下来的,原来这一切根本是由不得自己的!”然后,她就说:“妈妈,带我去蒙古。”
