Smoking is very popular among Chinese people. Nowadays, the number ofsmokers during teenagers is increasing. Some treat smoking as fashion and followsuch bad behavior. Though many people have been educated the danger of smoking,they still do not fear it.
吸烟很受中国人的欢迎。如今，青少年吸烟者的数量与日俱增。有些人把吸烟当作时尚，追逐这样的不良行为。尽管许多人都被教育过吸烟的危害，但是他们并没因此而却步。
It is known to all that cancer has been the killer and the researches foundthat smoking for a long time will be easy to get cancer. I remembered myhometown, where people smoked a lot, especially the old generation, and theyformed this bad act when they were young. Then for a time, many people died ofcancer. People started to worry and they found that these people were heavysmokers.
众所周知，癌症是人类头号杀手，而且研究发现，长时间吸烟很容易患上癌症。我记得在我的家乡，吸烟的人很多，特别是老一辈，他们在他们年轻的时候就养成了这个习惯。然后有一段时间，很多人死于癌症。人们就开始担心了，后面他们发现这些人都是重度吸烟者。
The sad thing is that many teenagers smoke at their young age, and theyfeel cool to do it. Some adults smoke to relieve their pressure. No matter whatkind of reasons, the fact is that smoking not only hurt themselves, but alsohurt other people, because we know that second hand smoke is harmful, too. Foreverybody’s health and to live a better life, smoking should be stopped.
可悲的是，许多青少年在年轻的时候就吸烟，他们还觉得很酷。一些成年人用吸烟来缓解他们的压力。不管出于什么样的原因，事实是，吸烟不仅伤害自己，还伤害了别人，因为我们都知道二手烟也是有害的。为了每个人的健康以及生活得更美好，我们应该停止吸烟。
这可真奇怪呀!
在这世上有的人就是傻，放着新鲜的水果不吃，放着美味的佳肴不吃，放着可口的饮料不喝。偏偏去抽有毒的烟，难道烟的价胜过水果、佳肴、饮料吗?我想不一定吧。
在化学学习中我知道了一氧化碳中有剧毒，易与人体血蛋白结合，使人中毒，而烟草中恰恰又有这种种物质。在众多资料统计中我国每天因吸烟死亡的人数达4000多万，这不得不是一个惊人的数字。或许有人认为我这是危言耸听，可这恐怖数字难道不能引起广泛烟民的重视吗?
我在一个实验中看到一个这种现象，将60支烟同时点燃，自动吸食5分钟后，再收集烟雾，而在收集瓶有两只活磞乱跳的老鼠，2分钟后，老鼠就趴在地上一动不动。实验说明如果人同时抽60支烟，也会当场死亡，所以同理我们知道一根一根的抽，不易于慢性自杀。所以不要小看一支烟带来的危害。
据相关资料报道，二手烟的危害比一手烟还大，那么就是说一个小孩不抽烟，可家人在他旁抽一支烟，意味着他无形之中抽了两支烟。现在青少年吸烟的人也逐年增长，我想如果要批评孩子吸烟，先得批评家长。家里没有吸烟的家长，哪来吸烟的孩子。
吸烟能带来什么?吸烟只能带来对健康的危害!
