“吸烟有害健康”在这个话题一直被人们关注着，大家都知道吸烟对我们的健康有着极大的伤害。近50多年来，世界各国特别是工业发达国家，肺癌的发病率和病死率均迅速上升，死于癌病的男性病人中肺癌已居首位。大量流行病学研究证实，吸烟是导致肺癌的首要危险因素。为了引起国际社会对烟草危害人类健康的重视，世界卫生组织建议将每年的5月31日定为世界无烟日。

香烟中的尼古丁、一氧化碳和多种其它金属化合物对人体危害很大，对青少年的影响更甚。据医学研究表明，青少年正处在生长发育时期，各生理系统、器官都尚未成熟，其对外界环境的有害因素的抵抗力比成人弱，易于吸收毒物。据调查，吸烟开始年龄与肺癌死亡率直接相关。

15岁以下开始吸烟者死亡率为19.68%;20～24岁为10.08%;25岁以上为4.08%。这说明吸烟开始年龄越早，肺癌发生率与死亡率越高。同时，吸烟还会损害大脑，使思维变得迟钝，记忆力减退，影响学习和工作，使学生的学习成绩下降。心理研究结果表明，吸烟者的智力效能比不吸烟者低了10.6%。

我们也常听人说“饭后一支烟，快乐像神仙”，可事实并非如此。吸烟的坏处就像繁星点点，数也数不完。烟草里有三种危险化学物质：焦油，尼古丁和一氧化碳。

焦油是由好几种物质混合成的物质，在肺中会浓缩成一种粘性物质;尼古丁是一种会使人成瘾的药物，由肺部吸收，主要是对神经系统发生作用;一氧化碳能减低红血球将氧输送到全身去的能力。其实烟也是一种毒品，只是没有那么剧烈，国家没有禁止而已。

吸烟不仅会对自己的身体造成威胁，还会对你身边那些被动吸烟的人也造成极大的危害。这一根根烟头，就像一只只毒药，徐徐的向我们逼近，给我们的生活和工作也带来了极大的威胁。假如你每天都处在烟雾中，你的身体会越来越虚弱，病魔会时时侵害你，甚至危及你的生命。

可怕的是：一个每天吸15到20支香烟的人，极易患肺癌、口腔癌或喉癌致死的机率，要比不吸烟的人大14倍;极易患食道癌致死的机率比不吸烟的人大4倍;比死于膀胱癌的机率要大两倍;死于心脏病的机率也要大两倍。吸香烟是导致慢性支气管炎和肺气肿的主要原因，而慢性肺部疾病本身，也增加了得肺炎及心脏病的危险，并且吸烟也增加了高血压的危险。

现在，我郑重的呼吁大家，积极宣传吸烟有害健康的科学知识，让你的亲人、朋友放下手中的烟，形成禁烟的良好氛围，把禁烟纳入精神文明建设的轨道。

我们都要做“无烟青少年”做文明的主人!

让我们一起和家人幸福的生活，一起创造美好的未来吧!

i believe it is in my nature to dance by virtue of the beat of my heart,the pulse of my blood and the music in my mind. so i dance daily.

the seldom-used dining room of my house is now an often-used ballroom — anopen space with a hardwood floor, stereo, and a disco ball. the cd-changer hassix discs at the ready: waltz, swing, country, rock-and-roll, salsa, andtango.

each morning when i walk through the house on the way to make coffee, iturn on the music, hit the "shuffle" button, and it's dance time! i dance aloneto whatever is playing. it's a form of existential aerobics, a movingmeditation.

tango is a recent enthusiasm. it's a complex and difficult dance, so i'm upto three lessons a week, three nights out dancing, and i'm off to buenos airesfor three months of immersion in tango culture.

the first time i went tango dancing i was too intimidated to get out on thefloor. i remembered another time i had stayed on the sidelines, when the dancingbegan after a village wedding on the greek island of crete. the fancy footworkconfused me. "don't make a fool of yourself," i thought. "just watch."

reading my mind, an older woman dropped out of the dance, sat down besideme, and said, "if you join the dancing, you will feel foolish. if you do not,you will also feel foolish. so, why not dance?"

and, she said she had a secret for me. she whispered, "if you do not dance,we will know you are a fool. but if you dance, we will think well of you fortrying."

recalling her wise words, i took up the challenge of tango.

a friend asked me if my tango-mania wasn't a little ambitious. "tango? atyour age? you must be out of your mind!"

on the contrary: it's a deeply pondered decision. my passion for tangodisguises a fearfulness. i fear the shrinking of life that goes with aging. ifear the boredom that comes with not learning and not taking chances. i fear thedying that goes on inside you when you leave the game of life to wait in thefinal checkout line.

i seek the sharp, scary pleasure that comes from beginning something new —that calls on all my resources and challenges my mind, my body, and my spirit,all at once.

my goal now is to dance all the dances as long as i can, and then to sitdown contented after the last elegant tango some sweet night and pass on becausethere wasn't another dance left in me.

so, when people say, "tango? at your age? have lost your mind?" i answer,"no, and i don't intend to."

我相信，随着心跳、脉搏以及心中的音乐去跳舞是我的天性。所以我每天都跳。

我屋子里那个很少使用的餐厅，现在经常被用来作“舞厅”——一个铺着硬木地板、配有立体音响装置的迪厅。我的换片箱里备好了6张碟片：华尔兹、摇摆、乡村、摇滚、萨尔萨和探戈。

每天早上，在去煮咖啡的路上，我都把音乐打开，并摁下“随机”键。跳舞的时间到了!不管放的是什么曲子，我都会随着曲子独自起舞。这是一种关乎存在的增氧运动，一种动起来的沉思。

探戈最近很火爆。这是一种很复杂的比较难跳的舞，所以我一周要上三次课，花三个晚上出去跳舞，我还打算去布宜诺斯艾利斯待三个月，接受探戈文化的浸礼。

第一次去上探戈舞蹈课的时候，我非常害怕，都不敢到地板上去。我还记得，有一次，在希腊克里特岛上，一场乡村婚礼之后，舞会开始了，而我却一直待在旁边不敢跳。那高超的步法让我眼花缭乱。“别做傻事了，”我想，“就看看吧。”

一位年龄比我还大的女士看出了我的想法，她从舞场中退出来，坐在我旁边说，“如果加入这场舞会，你会觉得很傻。如果你不加入，你一样会觉得很傻。既然这样，干吗不跳?”

然后，她说她要告诉我一个秘密。她低声说道：“如果你不跳，我们就会知道你是个傻瓜。可是如果你跳了，我们就会因为你的尝试而觉得你很棒。”

听了这席话，我接受了探戈的挑战。

一个朋友问我，我对探戈的嗜好是不是有点儿太狂野了。“探戈?你这个年龄?你一定是精神不正常了!”

恰恰相反：这是我深思熟虑之后的决定。我对探戈的热情掩盖了一种害怕。我害怕生命随着年龄的增长而缩短。我害怕因为不再学习、不再冒险而产生的无聊。我害怕在退出生命之局而等着末日审判的过程中，你体内发生的死亡。

我追寻那种随着新事物而产生的，尖锐而略带惊吓的喜悦——这就要求我全身心投入，对我的心智、身体和勇气同时进行挑战。

我现在的目标就是：跳完所有我能跳的舞蹈，然后，在某个甜蜜的夜晚，跳完最后一支优雅的探戈后，满意地坐下来，离开世界——因为我体内没有一支没有跳过的舞了。

所以，当人们说，“探戈?你这个年龄?精神不正常吧?”我便回答：“没有啊，我可不想不正常。”

尊敬的各位领导、各位评委、老师们：

大家晚上好!

我演讲的题目是。人民教师是人类灵魂的工程师，是太阳底下最光辉的职业。教师既是一个光荣的称号，又是一个崇高的使命，更有着传播人类文明的重要责任在里头。有的人说教师像蜡烛，燃烧自己，照亮别人;有的人说教师像航灯，指明方向，照亮前程;也有的人说教师像春蚕，吃的是绿叶，吐的是银丝。但我认为，教师更应该是学生的父母，为人父者、为人母者哪有不爱自己孩子的啊?!除了那份爱，沉甸甸压在身上的还有那教育孩子的责任!所以，为人师者对学生要有爱心，要有责任心。“爱”与“责任”，二者其实是分不开的，“爱”是责任的体现，而“责任”是爱的化身。没有爱就没有教育，没有责任也办不好教育。高尔基说过：“谁不爱孩子，孩子就不爱他，只有爱孩子的人，才能教育孩子”。爱学生是教师应具备的美德，也是教师的天职。师爱比渊博的知识更重要。能够得到教师的关爱，是每个学生最起码的心理需求，师爱对学生来说是一种鞭策和激励，对学生的成长和进步有很大的推动作用。师爱即严慈相济的爱，是只讲付出，不计回报地爱，是无私广博的爱，学生只有“亲其师”才会“信其道”。我们中华民族自古以来就是勇于承担责任的民族，“天下兴亡，匹夫有责”，国家的繁荣富强最根本要靠教育，要靠有爱心和责任心的教师，爱心与责任心是优秀教师的首要素质。教师的责任感源于对教育事业的热爱及愿意献身教育事业的坚定信念。有了强烈的责任感与事业心，教师才会乐业、敬业，也才能一辈子“学而不厌，诲人不倦”。一个没有责任心的人不论其职位高低，是无法在其所处的岗位上敬业奉献的，也不可能成为一个优秀的教师。

教育部部长周济提出：“爱与责任”是“师德之魂”。“没有爱就没有教育”，“没有责任就办不好教育”。爱是无形的力量，爱是师德的核心，爱是教育的灵魂，是教育的桥梁，是教育的推动力，是教育成功的基础。作为一名合格的教师，爱只是一个最浅层次的要求，而德则是一个更高层次的要求。没有公德，社会就会沦落，没有师德，教育就会没落——师德是爱，更是一种责任!如果没有责任，没有责任意识，就不会明确自己的职守，不会明确自己肩负的历史重任，那就办不好教育，育不好学生。

“一日为师，终身为父”是学生对老师的尊敬之言。既然做“父亲”，就要关心爱护学生，对学生负责。古训说得好：“子不教，父之过，教不严，师之惰”。可见，对学生的爱也要体现在严格要求上。

教育家陶行知先生曾经说过，“你的教鞭下有瓦特，你的冷眼里有牛顿，你的饥笑中有爱迪生”。是的，我们的学生中将有无数的瓦特、牛顿、爱迪生，我们将以满腔的爱心赋予我们的学生。当学生们产生厌学情绪，我们动之以情，当学生犯了错误，我们晓之以理。我们每天都起早贪黑，因为我们当老师的都相信，每个孩子的心灵都是一颗纯净的种子，都会在教师爱的沐浴下，长成参天大树，也正因为如此，我们吃苦受累，甘受其乐。

教师个人对学生影响所产生的力量，无论是什么样的教科书、什么样的思潮、什么样的奖惩都代替不了的。在学校，教师是学生的表率，是学生的典范，是学生的楷模，其言行举止，甚至兴趣爱好等，都会对学生产生潜移默化的影响。正如杜甫诗句所言：“随风潜入夜，润物细无声。”艺术家常香玉在戏曲界是很有名的一个人，用现在的观点看，她是一个有很强的敬业精神的人，她把她的爱、她的一生都投在了她的事业上，她常告诫她的弟子“戏比天大”。“戏比天大”放在我们教师身上就是“教书育人比天大”。

总之，师爱是一种激励学生个性和谐发展的无可取代的教育力量。爱是阳光，能融化冰雪;爱是春雨，能滋生万物;爱是桥梁，能沟通师生的心灵。有了爱，师生之间就能以诚相见，心心相印，有责任心的老师热爱学生是搞好教育工作的先决条件。愿每一位教育工作者都能把自己的爱心、责任心无私的奉献给学生!用爱心、责任心换学生的心!

我的演讲完了，谢谢大家!

as americans gather to celebrate this week, we show our gratitude for the many blessings in our lives. we are grateful for our friends and families who fill our lives with purpose and love. we're grateful for our beautiful country, and for the prosperity we enjoy. we're grateful for the chance to live, work and worship in freedom. and in this thanksgiving week, we offer thanks and praise to the provider of all these gifts, almighty god.

we also recognize our duty to share our blessings with the least among us. throughout the holiday season, schools, churches, synagogues and other generous organizations gather food and clothing for their neighbors in need. many young people give part of their holiday to volunteer at homeless shelters or food pantries. on thanksgiving, and on every day of the year, america is a more hopeful nation because of the volunteers who serve the weak and the vulnerable.

the thanksgiving tradition of compassion and humility dates back to the earliest days of our society. and through the years, our deepest gratitude has often been inspired by the most difficult times. almost four centuries ago, the pilgrims set aside time to thank god after suffering through a bitter winter. george washington held thanksgiving during a trying stay at valley forge. and president lincoln revived the thanksgiving tradition in the midst of a civil war.

the past year has brought many challenges to our nation, and americans have met every one with energy, optimism and faith. after lifting our economy from a recession, manufacturers and entrepreneurs are creating jobs again. volunteers from across the country came together to help hurricane victims rebuild. and when the children of beslan, russia suffered a brutal terrorist attack, the world saw america's generous heart in an outpouring of compassion and relief.

the greatest challenges of our time have come to the men and women who protect our nation. we're fortunate to have dedicated firefighters and police officers to keep our streets safe. we're grateful for the homeland security and intelligence personnel who spend long hours on faithful watch. and we give thanks to the men and women of our military who are serving with courage and skill, and making our entire nation proud.

ladies and gentlemen, good morning. it’s my great honor to be here and i am very happy to see you all. thank you for being here. what i am going to talk about today is how to speak good english. making

first of all, i’d like to talk about the importance of speaking good english and share my experience in learning english with you. as you know, english has become an international language. wherever you go, english is always commonly used. it is convenient to know the language. at the same time, english may be the most important factor in deciding which countries are leaders in the future. the language of the most advanced management and technology is undoubtedly english. being able to absorb this information is really the key to the new century. in the 21century. we can’t go there and speak our own language because nobody is going to learn it in order to understand us. our asian rival, india, has surged ahead of other developing countries in information technology because of its superior english skills. unlewe are able to master english, we will not be able to get our population to use it and take advantage of the new economy. there is an urgent need to have a workforce which is proficient in the language in view of the information technology onslaught.

second, about learning english, i think laying a strong foundation is the first and most important step. in other words, you should read and speak english every day. memorizing new words and phrases is also helpful. of course, learning english takes some time, so don’t be impatient. remember, rome wasn’t built in a day. and then since english is not our native tongue, we must develop the muscles of your speech organs to produce unfamiliar sounds. when you read, read as loudly as possible, as clearly as possible and as quickly as possible. tongue muscles’ training is of importance in learning any foreign language.

third, if you want to speak good english, please don’t care how poorly well you speak, only care about catching the chances to speak. you must enjoy losing face, just forget about your face. the more you speak, the better your english will become. the more mistakes you make, the more progreyou will make. you must enjoy speaking poor english, because speaking is the only thing that will lead you towards success. don’t give up. just try your best. every time you move your mouth, your memory will deepen, your muscles will strengthen. you can make it.
