No Smoking in All Public Places
Some businees now say that no one can smoke cigarettes in any of their offices.Some governments have banned smoking in all public places.This is a good idea though it takes away some of our freedom.
As we know, smoking is harmful not only to our health but also to the environment.Smoking can lead to many diseases, such as lung cancer.Smoking affects non-smokers more than it does smokers.Ratio of paive smokers getting ill is higher than that of smokers.So, many nonsmokers are against smoking.
In public places, the harm of smoking is greater.This is connected with another effect of smoking.That is, smoking pollutes environment by giving much poisonous vapour off into the air.
Therefore, that the government ban smoking is very neceary and important to us. It is a measure to protect our health and environment.So many people, especially nonsmokers are Ior tile policy.
Some people say that it takes away some of our freedom.I think it is a one-sided view.If one wants to smoke, he may smoke in private, not in the public places.In fact, smokers still have the freedom of smoking.
But, I think, smokers had better give up smoking, not only in private places, but also in the public places, everywhere.It will be beneficial to all of us. [参考译文]
禁止在公共场所吸烟
现在，有些单位宣称没有人可以在他们的办公室里吸烟。有些国家已禁止在公共场所吸烟，这种做法很好，尽管它剥夺了我们一些自由。正如我们所知道的，吸烟不仅对健康不利而且对环境也不利。吸烟会导致多种疾病，例如：肺癌。烟气对不吸烟者的影响有甚于对吸烟者本人的影响。被动吸烟比吸烟人患病率要高。所以很多不吸烟的人反对吸烟。
在公共场合吸烟危害更大，这是吸烟产生的另外一种影响。那就是，吸烟所产生的大量有害气体会污染环境。因此，政府禁烟对我们来说是非常必要的和重要的。这是保护人类健康和环境的一个办法。所以有许多人，尤其是不吸烟的都赞同这一政策。
有些人说这会剥夺我们的一些自由。我认为这样的观点是片面的。如果某人想抽烟，可以在私人场合抽烟而不是在公共场合。实际上，烟民仍然有吸烟的自由。不过，我认为不仅仅是私下里，而且，在公共场合，在任何地方烟民最好放弃抽烟。这会有益于每个人。
二、Smoking
（1）、It is almost known to all that smoking is bad for people\'s health.Scientific researchs show that smoking can lead to heart disease,cancer and other problem.The World Health Organization says diseases linked to smoking kill at least two million five-hundred-thousand persons each year.
（2）、Still,many people find it difficult to stop smoking.One reason is that smoking usually becomes a habitual behaviour,and habits,whether good or bad are not easy to be given up.Another reason is the effect of nicotine,the substance found in cigarettes works on people somewhat as drugs do.
（3）、Measures have been taken to help people keep away from the harm of smoking.In many cities,smoking is forbidden in public places.The danger of smoking is warned of everywhere.And newspapers are asked not to publish advertisements for cigarettes.World \"No Tobacco Day\" is observed every year as the biggest compaign against smoking.

SECONDHAND SMOKE
[19] The studies didn\'t just point to the ill effects of smoking on those who smoke--non-smokers, too, are apparently affected by the smoke from their friends, family members and strangers who light up in their presence.[20] A steady stream of reports documented the statistical risks of contracting cancer or suffering from heart disease, even if you\'ve never put a cigarette to your lips.[21] The American Heart Aociation last fall released a seven-year study showing that never-smoking spouses of smokers have more than a 20 percent greater chance of death from coronary heart disease than those who have never smoked who live with non-smokers.That study gave more impetus to the drive to make workplaces and other public areas smoke-free.[22] The effects of smoking are hard on the children of smokers as well, the studies say.Dr.Claude Hanet of the St.Luc University Hospital in Bruels, Belgium, said earlier this year that a baby born to a smoking mother \"should be considered an ex-smoker\", [23] Hanet\'s study cautioned that cigarette smoke was more detrimental with decreasing age.[24] And a University of Birmingham, England, study, published in the British Journal of Cancer showed a poible link between fathers who smoked and an increased incidence of cancels in their children, while studies in the U.S.showed a poible link between smoking and DNA damage.被动吸烟
[19)研究不光指出了吸烟给烟民自己造成的危害，还指出了非吸烟者显然也会受到他们吸烟的朋友、家人或在他们面前吸烟的陌生人的伤害。
[20]持续不断的报告通过统计数字证明，即使你从来就没有吸过烟，也有患癌症或心脏病的危险。
[21]去年秋季，美国心脏协会发表丁一份历时7年的研究报告，该报告指出，烟民的配偶虽然从不吸烟，但是和那些与非吸烟者生活的配偶相比，他们死于冠心病的危险要高出20％。这项调查进一步推动了在工作场所和公共场所禁烟活动的开展。
[22]调查还表明，烟民的孩子也深受吸烟之害。今年年初，比利时布鲁塞尔圣·卢卡大学医院的克劳德·哈内特博士说，吸烟的母亲生下的孩于“应被看作是有吸烟史的人”。
[23]哈内特的研究提请人们注意：年龄越小，吸烟的危害越大。
[24]《英国癌症杂志》发表的一份英格兰伯明翰大学的报告显示，吸烟的父亲与其孩子患癌症比率的增加可能有联系；同时美国的研究则显示吸烟和脱氧核糖核酸受损可能有关系。
