国旗下的讲话稿安全每一天各位老师、同学们:大家早上好!“安全”这个词对大家并不陌生,像“安全重于泰山”这样的警示更是时常见到。虽然安全十分重要,但在日常生活中有些人却总把安全抛在脑后,其实当他们把安全轻视的时候,危险就在慢慢向他们靠近。远的不说,回想一下在本学期,还记得我们邀请交警叔叔给大家做的安全讲座吧?那些就发生在我们周边的一个个交通事故的片段,你还印象深刻吗?是啊,当你看到一个个鲜活的生命消失于车轮之下,当你发现一阵阵欢声笑语湮没在尖锐的汽笛声中,当你面对那些触目惊心的场景时,能不感到震痛吗?这沉痛的案例发生的原因要么是违规驾驶,但更多的是因为行人没有按交通规则行走,闯红灯或没走斑马线。可见,一次小小的违规背后竟隐藏着巨大无比的杀机
国旗下的讲话稿爱护公物亲爱的老师,同学们:大家早上好!今天我要演讲的主题是《爱护公物 从我做起》一说起爱护公物,也许有人会认为这是老生常谈,因为类似“爱护公物光荣,破坏公物可耻”、“爱护公物,人人有责”这样的口号恐怕连幼儿园小朋友也能说上几条。但现实生活中的我们又做得怎么样呢?细心观察就会发现,校园里破坏公物的现象比比皆是:有的同学椅子不好好坐,使得椅子很快就坏了;在走廊和课桌椅上也经常会看见各式各样的涂鸦,短暂的课间时间更是成了“战场”,相互嬉戏间用力关门、踢门随处可见;我们学校的水龙头更换率也在不断的提升,诸如此类的事情还有很多……你们有没有想过,不论是有意还是无意,这些行为都对公物造成了损坏,也给其他同学的学习和生活带来了不必要的麻烦,还会增加学校对公物的维修费用,这可是一笔不小的开支。
《天道酬勤》各位老师,各位同学:大家好!今天,我国旗下讲话的题目是《天道酬勤》。当青春的翠绿催醒了温馨的校园,空气中渗透着早春的微凉,校园里到处绽放着青春的笑脸,在这样的一个时刻,我们迎来了一个全新的学期。又是一个新年的开始,又是一个新学期的开始,我们又来到了一个新的起点,迎接新一轮的挑战。俗话说:一年之计在于春。我们在春天里播撒文明、勤奋、乐学、健康、合作的种子,秋天里就会收获明礼诚信、乐学善思、身心健康、团结合作的丰硕成果。播种离不开耕耘,只有辛勤耕耘,我们才能学会求知、学会健体、学会合作、学会做事、学会做人,享受到进步的喜悦,享受到收获的幸福。这个学期对于我们来说,是一个重要的学期,也是一个冲刺的学期,因为高三毕业班的学哥学姐们为了圆自己的梦,即将背水一战。它又是一个奋斗的学期,因为高一、高二的同学们,也将为一个更高的目标而奋斗。
学会感恩亲爱的老师们、同学们:大家好!今天我讲话的题目是《学会感恩》。“感恩”是中华民族的传统美德,“滴水之恩,涌泉相报”“谁言寸草心,报得三春晖”,这是祖先为我们留下的教诲。怀着一颗感恩的心看世界,你才会真正幸福。父母的每一句关心的话语,你是否想到说一声“谢谢”,为了你的安全,为了你的温饱,为了你的成长,他付出的不仅是汗水,更多的是心血,对此,你是否有一颗感恩的心?每当你走进校园时,你会看见高大的树林,美丽的花草,整洁的教室,此时此刻的你是否想到这舒适的学习环境是学校、老师、同学们共同营造的?当我们能够这样幸福的在这样的环境中学习、生活,对此,你是否有一颗感恩的心?同学们,如果你心存感恩,当你因犯错误而受到老师的批评时,你应该虚心接受,因为你知道,老师是真心帮助你;当你每天都听到父母的唠叨时,你应该耐心倾听,因为父母是很爱你的。

《望天门山》是唐代诗人李白途径天门山时看到天门山的壮阔美景而诗兴大发,即兴所作。头两句描写山川气势。后两句写行船的感受。坐在小船上迎着阳光顺流而下,感觉两岸青山相对而来。诗歌通过对天门山景象和内心体验的描述,赞美了大自然的神奇壮丽,表达了乐观豪迈的情感。《饮湖上初晴后雨》这首诗作者以生动传神的笔墨描绘了西湖晴姿和雨姿的美好奇妙,?“晴方好”“雨亦奇”,是诗人对西湖美景的赞誉。诗的后两句“欲把西湖比西子,淡妆浓抹总相宜”,诗人用奇妙而又贴切的比喻,写出了西湖的神韵。《望洞庭》选择了月夜遥望的角度,把千里洞庭尽收眼底,抓住最具有代表性的湖光和山色,通过丰富的想象和形象的比喻,独出心裁的把洞庭美景再现于纸上,表现出惊人的艺术功力,给人以莫大的艺术享受。 1.认识“亦、宜”等5个生字,读准多音字“抹、磨”,会写“断、楚”等13个生字。2.有感情地朗读并背诵课文。默写《望天门山》。3.通过想象诗中描绘的景色,结合注释,联系上下文理解诗意与意境,体会诗人热爱祖国山河的感情。4.通过朗读感悟,激发学生对祖国山河的热爱之情。 1.教学重点:能结合注释,用自己的话说出诗句的意思,想象诗中描绘的景色。体会作者热爱大自然,热爱祖国山水的感情,感受诗歌美的意境。培养热爱大自然、热爱祖国的情感。2.教学难点:体会诗文的内容,体会诗人的思想感情。 3课时
《贫寒是福天道酬勤石智勇从挫折中奋起》也许是自幼的贫寒生活塑造了石智勇内向的性格,即使是胸挂金灿灿的奖牌接受全场观众欢呼,他的表情也是略显羞涩的。小时候吃不饱肚皮的经历让他至今在“最喜欢的东西”一栏还填写着“食物”二字,而“穷人的孩子早当家”的坚韧,却又是促成他今日辉煌的动力。中国举重队副总教练陈文斌赛后说道:“智勇这几年练得很苦,今天终于有了这样的成绩,这是天道酬勤的结果。石智勇的奥运会金牌是中国男举的一次突破,我们非常激动。”在希腊神话里,命运女神总是让英雄历经磨难。石智勇也不例外。四年前的悉尼奥运会前夕,他在一次训练中扭伤脚踝,失去了参赛机会。“当时我伤心极了,不敢看电视直播,我怕参赛的选手成绩太低了。高点我还好一点,自欺欺人一下说,哎呀好高,自己去了也拿不了冠军,要是低了,自己没去,失去冠军机会,心里痛啊。后来结果出来,也不怎么高,心里真难受。”

The theme of this section is to express people's views on studying abroad. With the continuous development of Chinese economic construction, especially the general improvement of people's living standards, the number of Chinese students studying abroad at their own expense is on the rise. Many students and parents turn their attention to the world and regard studying abroad as an effective way to improve their quality, broaden their horizons and master the world's advanced scientific knowledge, which is very important for the fever of going abroad. Studying abroad is also an important decision made by a family for their children. Therefore, it is of great social significance to discuss this issue. The theme of this section is the column discussion in the newspaper: the advantages and disadvantages of studying abroad. The discourse is about two parents' contribution letters on this issue. They respectively express their own positions. One thinks that the disadvantages outweigh the advantages, and the other thinks that the advantages outweigh the disadvantages. The two parents' arguments are well founded and logical. It is worth noting that the two authors do not express their views on studying abroad from an individual point of view, but from a national or even global point of view. These two articles have the characteristics of both letters and argumentative essays1.Guide the students to read these two articles, and understand the author's point of view and argument ideas2.Help the students to summarize the structure and writing methods of argumentative writing, and guides students to correctly understand the advantages and disadvantages of studying abroad3.Cultivate students' ability to analyze problems objectively, comprehensively and deeply

(2)l的倾斜角为90°,即l平行于y轴,所以m+1=2m,得m=1.延伸探究1 本例条件不变,试求直线l的倾斜角为锐角时实数m的取值范围.解:由题意知(m"-" 1"-" 1)/(m+1"-" 2m)>0,解得1<m<2.延伸探究2 若将本例中的“N(2m,1)”改为“N(3m,2m)”,其他条件不变,结果如何?解:(1)由题意知(m"-" 1"-" 2m)/(m+1"-" 3m)=1,解得m=2.(2)由题意知m+1=3m,解得m=1/2.直线斜率的计算方法(1)判断两点的横坐标是否相等,若相等,则直线的斜率不存在.(2)若两点的横坐标不相等,则可以用斜率公式k=(y_2 "-" y_1)/(x_2 "-" x_1 )(其中x1≠x2)进行计算.金题典例 光线从点A(2,1)射到y轴上的点Q,经y轴反射后过点B(4,3),试求点Q的坐标及入射光线的斜率.解:(方法1)设Q(0,y),则由题意得kQA=-kQB.∵kQA=(1"-" y)/2,kQB=(3"-" y)/4,∴(1"-" y)/2=-(3"-" y)/4.解得y=5/3,即点Q的坐标为 0,5/3 ,∴k入=kQA=(1"-" y)/2=-1/3.(方法2)设Q(0,y),如图,点B(4,3)关于y轴的对称点为B'(-4,3), kAB'=(1"-" 3)/(2+4)=-1/3,由题意得,A、Q、B'三点共线.从而入射光线的斜率为kAQ=kAB'=-1/3.所以,有(1"-" y)/2=(1"-" 3)/(2+4),解得y=5/3,点Q的坐标为(0,5/3).
尊敬的老师,亲爱的同学们:今天国旗下讲话的题目是:“说说爱国卫生月”。同学们,四月是个春暖花开的季节,可你还知道四月是个什么月吗?告诉你吧,四月是全国爱国卫生月。因为卫生工作关系到每一个人,所以请大家在日常工作、学习、生活中积极主动做好卫生工作,保持良好的正确的卫生习惯,促进健康成长。1、保持良好的个人卫生习惯,注意饮食卫生,不能在路边小摊随便购买食品,因为路边摊卫生根本就不能得到保证,各种尘埃、苍蝇、不干净的食品用具等都隐藏着多少有害细菌,但是我们有时也发现有的同学在放学后就喜欢在这些路边小摊驻足购买食品,这是非常不卫生的。在个人卫生习惯中,养成饭前便后要洗手,勤剪指甲,勤洗澡,不随便使用别人的生活用品,如毛巾、衣服、拖鞋、餐具等。遵守作息时间,做到起居有规律。2、均衡饮食,随气候变化而增减衣服,定期运动,充足休息。在日常生活中同学们应该按照生活规律,定时用膳,三餐饭做到定量,不能饿一餐,饱一餐,特别是早晨,我们有的同学就往往因为睡懒觉而未吃早餐,这对身体健康和学习精力都是不利的。同学们早晨起床后到户外锻炼,呼吸一些新鲜的空气,伸伸腰,踢踢腿,跑跑步都是很有好处的。
《小狗学叫》这篇童话通过拟人的手法,叙述的是一只小狗学叫的故事。构思新颖,想象丰富,作者的情思寄寓在形象的描写中,耐人寻味。故事读起来看似有点荒诞无稽,但细品之后谁也不会去怀疑和谈论故事的真实性,而是深刻地思考品评故事所暗示的“小狗终于做成真正的狗,找回迷失的自我”的主题。作者曾经说过:“在每一件事物中都有一个故事,这些故事在桌子的木头中,在玻璃中,在玫瑰中……” 《小狗学叫》正是以现实生活为基础,在每一件事中挖掘故事,把现实世界的偶然现象和必然因素统一起来,把故事情节的曲折变化和人物性格的逻辑发展结合起来,通过这一高超的艺术辩证法,幽默地展示出现实社会中的某些现象,使人们在笑声中受到教育和启发。我们可用多媒体课件等形象的教学手段,拉近学生与文本之间的距离。 1.会认“讨、厌”等11个生字,读准“吗、担”等5个多音字。2.能预测故事的结局,并将自己的预测与原文进行比较,体会预测的多样性,培养学生听故事的技巧和预测故事结局的能力。3.通过分角色朗读,在观察、想象、表演中,让学生感受阅读的乐趣。4.引导学生正确认识自我,发现自己的潜力,能够做好自己。 1.教学重点:培养学生听故事的技巧和预测故事结局的能力,能根据故事发展寻找推测故事结局的依据。2.教学难点:培养学生认真思考、仔细推敲的探究习惯。 1课时
