文档介绍：No Smoking in All Public Places
    Some businesses now say that ao one call 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 for the 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 ail of us.

    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。
