吸烟所带来伤害和疾病有些是致命的,像肺癌和一些其他呼吸道疾病。
烟里面有尼古丁,还含有焦油等有害物质。另外,烟的另一个坏处就是,如果吸上了就很难戒掉。我爸爸就是一个典型的例子。
我爸爸自从吸上烟后,就从来没有停过,一天起码可以抽一包烟,我曾多次劝告他戒烟,但都没有效果。
由此可见,吸烟对人的危害有多大,所以每个大人都不应该吸烟。
There are many students smoking in senior high school, the reason may be that they think they look cool or appear to be more mature while having a cigarette at hand.But there are a lot of reasons not to smoke. Smoking does harm to our health.It is dangerous to our heart and lung. A lot of diseases are caused by cigarettes.Cigarettes also have terrible smell.The seconghand smoke can also be dangerous to the others who stand around you. Therefore, no smoking in public is a strict regulation in many countries. And the most important thing is that once you come into addicitive,it's hard to get rid of it. So,we must keep far from the cigarette——for everybody's health.
高中里有很多学生吸烟,原因可能是他们觉得手中有一支烟看上去很酷或者显得更成熟。但是,不吸烟的原因有很多。吸烟有害我们的健康,对我们的心脏和肺很危险。很多疾病都是由香烟引起的,而且烟的味道不好闻。二手烟对周围的.人也很危险。因此,公共场所禁止吸烟是很多国家的一项严厉规定。最重要的是,一旦你上瘾了就很难戒掉了。所以,为了每个人的健康,我们必须远离香烟。
我利用寒假,制作了一个实验装置来验证吸烟对肺部的影响:
设计目标:
通过演示试验了解吸烟对身体的严重危害性。从而引导同学们开展“拒绝吸烟”、“劝戒行动”进行创新活动设计。在活动中知道自觉拒绝香烟,维护自己的权益、维护环境。
装置材料:
一个透明的瓶子矿泉水瓶(含盖子)、香烟、橡皮膜、面巾纸等
装置制作:
取矿泉水瓶盖,在瓶盖上钻一个孔,使一支香烟能够正好卡住,将矿泉水瓶去底,在上面蒙一层橡皮膜用胶水粘牢,松紧要适度,沿瓶盖内部边缘粘一层面巾纸,盖上瓶盖,这样一个简易的实验装置就制作完成了。
实验操作过程:
将一支香烟点燃,插在瓶盖事先打好的孔上,点燃部分向上,模拟人口吸烟过程,来回拉动矿泉水底部的橡皮膜,模拟人的呼吸,这时会发现有烟进入瓶中,而渐渐的会使面巾纸变成黄色,产生很多烟油附在纸巾上(面巾纸模拟人体肺部肺泡),而如果长时间拉动橡皮膜的话瓶子内就会形成一层尘垢。(瓶子模拟人体肺部)。
实验总结:
本实验通过运用材料,模拟了人体吸烟对人体危害的.过程,橡皮膜的拉动,模拟人不断呼吸、面巾纸模拟人体肺部肺泡、瓶子模拟人体肺部,通过一系列实验最终验证了吸烟有害健康。并且说明了吸烟对人体肺部的影响,从而告诫人们切勿吸烟本实验装置材料完全取材于生活,都是一些身边的物品,并且切实地说明了吸烟有害健康这一主题,制作简单,容易操作,实验效果明显使大家直观的了解实验结果,使大家明白吸烟几乎损害人体全部重要器官。对于这一点很多人不以为然,因为这需要时间证明,但我们绝不做此实验的试验品!能够使同学们通过自己动手做实验明白烟对人体的危害,从而达到使同学们远离香烟,拒绝吸烟,永于向香烟说“不!”还可以激发同学们的学习兴趣,促使同学们不断创新,不断努力,向着科学的世界冲!冲!冲!为了我们自己的健康,我们呼吁,全体同学都要自觉地远离香烟,并劝说吸烟的亲友尽量戒烟。毕竟,香烟对我们有害无益;毕竟,没有烟雾的空气会更加清新,没有烟草的生命会更加绚烂!同学们,让我们行动起来,从现在做起,从自我做起,严格控烟,向更多的人宣传吸烟有害健康的公益知识,呼吁全社会都珍惜自己和他人的生命,自觉控烟,坚决拒绝“二手烟”。使我们的天空更加湛蓝!使我们的明天更加辉煌!
Smoking is a bad habit that does harm to smoker and others. Many kinds of diseases and cancers are caused by smoking, such as tracheitis, lung cancer and many other diseases. Recent years, there are tens of thousands of people dying of smoking. But there still are many people enjoying smoking, because they think smoking is a kind of fashion and smoking is so cool, especially among teenagers. In addition, smoking does harm to others as well. Second hand smoking has been recognized harmful to other people. Even worse, it may cause more damages. Therefore, people should remember that smoking is harmful to others and those people who smokes should give up smoking as soon as possible.
吸烟是个坏习惯,它对吸烟者和别人都有害。很多疾病和癌症是有吸烟引起的,比如说气管炎,肺癌还有很多其他疾病。近年来,成千上万的人于吸烟。但是仍然有很多人喜欢吸烟,因为他们认为吸烟是一种时尚,很酷,特别是青少年。另外,吸烟也会对别人有害。二手烟是公认的对别人有害的。更糟糕的是,它会带来更多伤害。因此,人们应该牢记吸烟有害他人,那些吸烟的人应该尽可能戒烟。
