创无烟环境,过健康美好的生活&&是我们每个人的理想。吸烟有害健康在这个世纪流传广泛,大家都知道吸烟对我们的健康有着极大的伤害。我想,同学们的爸爸大多有吸烟这个坏习惯吧。同学们可能都想脱离这个云雾缭绕的环境吧,可我们不但没有脱离,也许还会越陷越深哪!所以,同学们都应该奉劝亲人,远离危害!
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,何况很多人都爱抽烟呢。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。
敬爱的叔叔阿姨们,你们在抽烟时想过后果么?吸烟不仅对自己的身体造成威胁,还对你身边那些被动吸烟的人也造成了极大的危害。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。
听了这一句句惊心动魄的描述,你感觉到危险正向你慢慢的.逼近了吗?你体会到自己那饱受痛苦的***了么?想一想,吸烟除了带来危害,它能给予你什么?给予你家人为了你抽烟而闹得家庭不和么?所以奉劝那些有烟瘾的朋友们好好的想一想吸烟的危害,及时戒烟吧!为了防止越来越多的人吸烟,仅仅靠一个人的力量是不够的,我们大家应该团结起来,去掉这一大不良习惯和危害。
现在,我郑重的呼吁大家,放下手中的烟吧!让我们一起和家人幸福的生活,一起创造美好的未来吧!
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!
Today smoking is a widespread habit ali over the world. Not only the old, the youth, but also middle school students have been engaged in smoking. Many of them think that smoking is a smart symbol.
However, smoking is harmful to one's health. It contributes a lot of lung cancer, from which many people have died in the past years. It can also cause many other diseases. In a word, if you smoke, you do have a much greater chance of losing your health. Furthermore, scientific research shows that smoking is not only harmful to smokers themselves, but also a threat to public health, especially to women and children. Therefore, many countries have made laws forbidding smokers to smoke m public places such as cinemas, stations, hospitals, and so on Giveup smoking! If you don't smoke, don't start. Give upsmoking for the sake of your health, for the sake of your family, and for the sake of the whole world.
当今吸烟是一个世界范围内的习惯。不仅是老人,青年,而且中学生都吸烟。他们中的许多人认为吸烟是一种潇洒的象征。
然而,吸烟有害人的健康。它会引起肺癌,其中许多人在过去的一年都死去了。它还可以造成许多其他疾病。总之,如果你吸烟,你有更大的机会失去你的健康。此外,科学研究显示,吸烟不仅对吸烟者有害,而且对公众健康构成威胁,尤其是对妇女和儿童。因此,许多国家都制定了法律禁止吸烟如电影院,车站,医院等公共场所禁止吸烟,如果你不抽烟,不要开始。戒烟吧,为了你的健康,为了你的家庭,和世界。
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。
I attended Jack's birthday party tonight. After dinner, Jack gave cigarets to our boy students present.
At the important moment, I stop them and told them the bad effects of smoking: firstly Smoking is a waste of money and it's greatly harmful to our health. And it can lead to fires easily. So we should not smoke at all.
But it seemed helpless and they wouldn't listen to me. Somebody even said that body and health belonged to themselves and it's up to them to decide whether to smoke or not. I told him calmly, "Even if you have the right to harm your own body, but it doesn't mean that you have the same right to harm others'."
At last, they agreed with me, and some students said that they would never smoke any longer.
For the next one hour, we danced and sang happily, and nobody did smoke again.I felt very happy that my classmate all understood the harmness of smoking.
我今晚参加了杰克的生日派对。晚饭后,杰克给我们的男同学吸烟。
在重要的时刻,我阻止并告诉他们吸烟的不良影响:首先,吸烟很浪费钱,它对对我们的健康危害很大。它会很容易引起火灾。所以我们不应该吸烟,所以我们不能吸烟。
但很无奈似乎他们不听我的。甚至有人说身体是自己的,这是是否吸烟由他们自己说了算。我平静地说,“即使你有伤害自己身体的权利,但这并不意味着你要伤害别人的权利。”
最后,他们同意我的看法,一些学生说他们不会再抽烟了。
在接下来的一个小时里,我们跳舞,唱歌,没有人吸烟了。我感到非常高兴,我的同学都知道了吸烟的危害。
the sun rises in the east and sets in the west, which is caused by the rotation of the earth as you all know. but have you ever thought of the effect of the earths rotation on man and can you imagine what would happen if the earth stopped rotating?
the radius of the earth is about 6,370 kilometres. it takes the earth 24 hours to rotate once. objects on the earths equator move with the earth at a speed of 460 metres per second, and the air close to the earths surface turns at the same speed. if the earth stopped rotating suddenly, the air would keep flowing eastward at a speed of 460 metres per second. the wind would be fourteen times as powerful as a hurricane. at the same time sea water would rush eastward at a speed of several hundred metres per second, which might do damages much greater than a seaquake would do. obviously, men could hardly stand such a catastrophe.
even if such a catastrophe would not happen, there would be a great temperature difference on the two hemispheres of the earth, and the four seasons of the year would no longer occur because a day and a night would be as long as a whole year instead of 24 hours. all this would greatly affect the life of human beings, imals and plants and that would cause worse results than anything imaginable.
