双语阅读：烟的成分

 On the whole smoking is very harmful and it does no good！

吸烟对健康百害而无一益

   大家都知道吸烟有害健康，那到底是哪些东西在伤害我们的健康呢？

尼古丁（nicotine）

The most harmful ingredients

最有害的成分

Nicotine contained in a cigarette can be a poisonedmouse

一支香烟的尼古丁可毒死一只小白鼠

20 of the nicotine in cigarettes can kill a cow

20支香 烟中的尼古丁可毒死一头牛

一氧化碳(carbon monoxide)

Carbon monoxide poisoning

一氧化碳中毒：

Give rise to mental retardation 、Hemiplegia、Neurasthenia

会引起智力障碍、偏瘫、神经衰弱症

酚类化合物Phenolic compounds

Have to the role of cancer

有促使癌症的作用

醛类Aldehydes

Stimulate the respiratory mucosa

对呼吸道粘膜产生炎症刺激

Cigarette smoke (In particular, the tar) Is a carcinogen.That is to say, It can come into contact with in the organization have cancer, So, Smokers of any part of respiratory tract (Including the mouth and throat) cancers may have occurred.

烟的烟雾（特别是其中所含的焦油）是致癌物质——就是说，它能在它所接触到的组织中产生癌，因此，吸烟者呼吸道的任何部位（包括口腔和咽喉）都有发生癌的可能。

Nicotine can speed up heart rate, High blood pressure, May be due to cigarette smoke contains carbon monoxide, Seem to be able to accumulate atherogenic, And this is one of many reasons for heart disease, Smokers, When a heart attack,Their chances of death much larger than non-smokers.

尼古丁能使心跳加快，血压升高，烟草的烟雾可能是由于含一氧化碳之故，似乎能够促使动脉粥样化累积，而这种情形是造成许多心脏疾病的一个原因，大量吸烟的人，心脏病发作时，其致死的机率比不吸烟者大很多。

Most smokers prefer to swallow a certain amount of smoke, Digestive tract diseases (Especially in the esophagus and pharynx) therefore there is the risk of cancer.

大多数吸烟者喜欢将一定量的烟雾吞下，因此消化道（特别是食道及咽部）就有患癌疾的危险。

Lungs in the gas along with the fine, Hydrogen is usually outside the lung tissue were excluded from. These villi to the lungs consecutive sweep of the particles in phlegm or mucus, to discharge, Tobacco smoke inaddition to cancer-causing chemicals, Will gradually undermine the number of villi, So that increased mucus secretion, Thus the occurrence of chronic lung disease, Susceptible to bronchitis. Obviously, Smokers cough, Clean as a result of the mechanical performance of the lungs by the damages, Therefore increased sputum.

肺中排列于气道上的细毛，通常会氢外来物从肺组织上排除。这些绒毛会连续将肺中的微粒扫入痰或粘液中，将其排出来，烟草烟雾中的化学物质除了会致癌，还会逐渐破坏一些绒毛，使粘液分泌增加，于是肺部发生慢性疾病，容易感染支气管炎。明显地，“吸烟者咳嗽”是由于肺部清洁的机械效能受到了损害，于是痰量增加了。

通过以上对烟的化学成分分析，相信你已经看到了烟是由尼古丁、一氧化碳等化合物组成，都是一些危害身体的成分，如果长期食用，使得身体中这些物质量得到增加累积，那么，无法想象，10年，20年，30年，你的肺将会是什么样？那时，即使有清新的空气也滋润不了你肮脏的肺。关爱肺，就是关爱你自己。
