　　3.Smoking 抽煙

　　Since 1939, numerous studies have been conducted to determine whether smoking is a health hazard. The trend of the evidence has been consistent and indicates that there is a serious health risk. Research teams have conducted studies that show beyond all reasonable doubt that tobacco smoking is associated with a shortened life expectancy.

　　Cigarette smoking is believed by most research workers in this field to be an important factor in the development of cancer of the lungs and cancer of the throat and is believed to be related to cancer of some other organs of the body. Male cigarette smokers have a higher death rate from heart disease than non-smoking male s. Female smokers are thought to be less affected because they do not breathe in the smoke so deeply.

　　Apart from statistics, it might be helpful to look at what smoking tobacco does to the human body. Smoke is a mixture of gases, vaporized chemicals, minute particles of ash and other solids. There is also nicotine, which is powerful poison, and black tar. As smoke is breathed in, all those components form deposits on the membranes of the lungs. One point of concentration is where the air tube and bronchus divides. Most lung cancer begins at this point.

　　Filters and low tar tobacco are claimed to make smoking to some extent safer, but they can only slightly reduce, not eliminate the hazards.

　　除了統(tǒng)計(jì)之外，看一看吸煙對(duì)人體的作用也可能會(huì)有幫助。煙是各種氣體、蒸發(fā)的化學(xué)物、微小的灰和其他固體顆粒的混合物。里面還有很強(qiáng)的毒素尼古丁和黑焦油。當(dāng)煙被吸入時(shí)，所有這些成分形成肺膜上的沉淀物。集中的一點(diǎn)是氣管和支氣管分叉的地方。大部分肺癌開始于這一點(diǎn)。

　　過濾嘴和焦油含量低的煙草被宣稱使抽煙在某種程度上安全一些，但是它們只能稍微降低而不是消除危害。
