Slowly add 5mL or 10mL sulfate, after treating the ease stops foaming, low heat, slowly heating (sugar easy charring), continue along the wall added nitric-perchloric acid 师:同学们观察得真仔细，刚才老师展示的只是香烟对人体里肺的危害，只是一方面，其实香烟燃烧时会极大地危害人体全身的健康。 2、讲解吸烟吸烟引至慢性中毒的各种病症: 师出示课件:《吸烟对人体健康的危害》 3、释疑:为什么没有吸烟急性中毒呢, 师:香烟燃烧时产生多种有害物质，主要是烟碱(尼古丁)、烟焦油和一氧化碳。尼古丁是一种剧毒物质，实验证明，一支香烟所含的尼古丁为5至15毫克，是可毒死一只老鼠，20支香烟的尼古丁可毒死一头牛。尼古丁的致死量为50—70毫克，相当于20—25支纸烟的含量。为什么没有吸烟急性中毒呢, ?、吸烟时烟草中的部分尼古丁被烟雾中的毒物甲醛中和了，而且大多数不是连续吸烟，这些尼古丁是间断缓慢进入人体的。 ?、此外纸烟点燃后50%的尼古丁随烟雾扩散到空气中，5%随烟头被扔掉，25%被燃烧破坏，只有20%被肌体吸收。?、长时间的吸烟者体内对尼古丁产生耐受性。 1. 烟情分析: ?我国是世界上烟民最多的国家，有3.5亿烟民，并因此制造了5.4亿被动吸烟者，其中15岁以下儿童有1.8亿。据世卫组织统计，目前全球每年约有500万人因吸烟而死亡，烟草已成为继高血压之后的第二号“杀手”。世卫组织估计，如果不加以控制，到2020年每年吸烟致死的人数有可能增加一倍。在全球13亿烟民中，有6.5亿人会因为吸烟而过早死亡。 师:由此可见，吸烟的后果多么可怕。这段话里 有一个词:被动吸烟者。 ?被动吸烟者是指哪些人, 被动吸烟者:是指生活和工作在吸烟者周闱的人们不自觉地吸进烟雾尘粒和各种有毒的物质。 to produce white smoke, so twice, cold.

Slowly add 5mL or 10mL sulfate, after treating the ease stops foaming, low heat, slowly heating (sugar easy charring), continue along the wall added nitric-perchloric acid ?香烟对被动吸烟的人有什么危害, 被动吸烟15分钟等于主动吸烟: а、戒烟网最近发表研究报告指出，被动吸烟即俗称的 “吸二手烟”比原先外界所知道的还要危险，一些与吸烟者共同生活的人，患肺癌的机率比常人多出 6倍。 в、被动吸烟对婴幼儿、青少年及妇女的危害尤为严重。对儿童来说，被动吸烟可以引起呼吸道症状和疾病，并且影响正常的生长发育;对于孕妇来说，被动吸烟会导致死胎、流产和低出生体重儿;被动吸烟亦会增加成人呼吸道疾病、肺癌和心血管疾病发病的危险。 1. 怎样减少香烟的危害? (1)、认识禁烟标志: , 引导学生回忆健康标志。 (幻灯片出示禁烟标志) , 你在什么地方看到过禁烟标志, 有禁烟标志的场所: 宾馆、饭馆、影剧院、体育场(馆)、游泳场(馆)、公园;展览馆、博物馆、美术馆、图书馆;商场(店)、书店;候诊室、候车(机、船)室;学校、医院、加油站等等。 任何社会成员都可以自由往来、停驻足或者只需购票就可以自由出入进行各种共同性活动的场所都是公共场所。 ?小结: 吸烟，污染环境，使空气变得浑浊，危害别人的身体健康，容易引起火灾，所以我们国家规定公共场所禁止吸烟，并把世界无烟日5月31日夜定为我们国家的无烟日，号召人们戒烟。 (2)、宣传戒烟: 你们家人吸烟吗,教师将数字统计出，让学生感受目前吸烟的人还是比较多，为了他和家人的健康，你有什么好办法劝诫哪些吸烟的人呢, to produce white smoke, so twice, cold.
