吸菸的危害英語演講稿 篇3
各位老師、同學們：
大家好！
今天我發言的題目是：“珍愛生命，拒絕吸菸。”
“香菸”這個詞對我們來說並不陌生。大人們常說；“飯後一支煙，賽過活神仙。”可事實上真的如此嗎？那么，接下來就讓我們聽一組統計數據，你便會知道要過上這“神仙般的日子“要付出多大的代價了。世界衛生組織的研究表明，全世界目前有菸民約13億人，每年有近500萬人因吸菸而死亡，菸草已成為繼高血壓之後的第二號殺手。如果不加以控制，到20xx年每年因吸菸致死的人數有可能達到1000萬。目前，全世界每13秒鐘有1人死於和菸草有關的疾病。我國每年約有200萬人死於與吸菸有關的疾病。吸菸會導致癌症，世界衛生組織證實30%的癌症和吸菸有關。長期吸菸者的肺癌發病率比不吸菸者高10—20倍，喉癌發病率高6—10倍，冠心病發病率高2—3倍，循環系統發病率高3倍，氣管炎發病率高2—8倍。
也許有人不相信或者不明白，小小的一支煙，怎么能有吞噬生命的力量呢？
原來，香菸中含有1400多種成分。吸菸時產生煙霧裡有40多種致癌物質，還有十多種會促進癌發展的物質，其中對人體危害的是尼古丁。一氧化碳和多種其他金屬化合物。一支煙所含的尼古丁就足以殺死一隻小白鼠。香菸煙霧中大量的一氧化碳同血紅蛋白的結合能力比氧大240—300倍，嚴重地削弱了紅細胞的攜氧能力，因此，吸菸是血液凝結加快，容易引起心肌梗塞，中風，心肌缺氧等心血管疾病。更為嚴重的是，吸菸者還嚴重妨礙他人健康。
菸草不僅對人的健康產生嚴重威脅，同時也會造成巨大的社會損失。大約有1/4—1/3的火災是由於吸菸不小心引起的。一個小小的菸頭，就可將寶貴的森林資源化為灰燼。
吸菸“百害而無一利”，影響健康，縮短壽命。明智的人，應該用金錢買健康，而不是用金錢買死亡。
現在，國家、社會，都在大力呼籲拒絕吸菸，可我們有些同學卻都沒有意識到吸菸危害健康的嚴重性，仍處於好奇，虛榮等心理躲在廁所、宿舍等地在偷偷地吸菸，甚至以吸菸為榮。殊不知，這是在摧殘自身的健康啊。所以，同學們，我們面對這種行為，一定要堅決說“不”！
作為新時代的青年，作為文明的文瀾高中人，我們不僅要勸自己的家長、身邊的親戚、朋友，儘量不抽菸或少抽菸；更要嚴格要求自己，拒吸第一支煙，做不吸菸的新一代！
謝謝大家！
