Some businesses 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 passive 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 necessary 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.

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。
