吸煙的危害英語演講稿 篇3
現(xiàn)在男子吸煙已經(jīng)成為潮流,世界有13億多煙民,其中超過四分之一是中國人。如今中學(xué)生在廁所吸煙并不罕見,殊不知吸煙有害健康。有很多成年人將吸煙有害健康這句話理解為“吸煙有害還健康”,實際上這句話的真正意義是吸煙對健康有害。
人體血液中含有血紅蛋白,學(xué)過生物的人都知道血紅蛋白能與氧氣結(jié)合或分離,但很少有人知道它也能與一氧化碳結(jié)合,而且結(jié)合能力很強,是氧氣的200--300倍,而且一旦結(jié)合便不容易分離,吸入大量一氧化碳人就會因缺氧窒息而死亡。這就是煤氣中毒的原因(煤氣中含有一氧化碳)。人在一氧化碳總濃度在百分之0。02的空氣中持續(xù)兩個小時就會出現(xiàn)中毒癥狀。香煙的煙氣中含有幾百種有毒有害物質(zhì),其中就有一氧化碳。除了一氧化碳,香煙中還含有尼古丁和含有強烈致癌物苯并芘、二惡英的焦油。有人曾用小白鼠做過實驗:把60支香煙的煙氣濃縮后讓小白鼠吸入,結(jié)果小白鼠因窒息和中毒而死亡。還有人把400支香煙的煙草浸泡在水里,水變成黑色后把它里面含有的水分蒸發(fā)掉后鍋底沉積了很多黑色的焦油。這些黑色物質(zhì)除了焦油之外還有劇毒物質(zhì)尼古丁等幾百種有害物質(zhì)。
吸煙的害處可不僅僅是中毒這么簡單。
一包香煙的價格大約是20元,每包一般20支。按每天抽一包來計算,20年一共抽掉14。6萬元。即使你不追求名煙,抽每包十元的普通香煙(同樣每包二十支,每天抽一包),20年也要抽掉7。3萬元!可見,香煙還危害人們的錢財。
更可怕的是,你抽掉的是你的生命!據(jù)研究,每抽一支香煙可縮短五分鐘壽命,也許有人會問五分鐘算不了什么,但每一秒累加起來就會變成一小時,每小時累加起來就會變成一天。按每天抽一包香煙(20支)計算,每天縮短生命100分鐘,一年就要縮短大約26天,一個煙民從25歲抽到55歲,每天抽一包香煙,就要少活兩年。所以,吸煙會對生命造成嚴(yán)重的危害!吸煙者吸入的尼古丁和焦油會沉積在肺部,久而久之就會釀成肺癌。
綜上所證,煙草屬于一種強烈的致癌物,長期吸煙等于花錢買罪遭。
