写作思路：可以从主张在公共场所禁止吸烟这个角度出发进行阐述，可以写出禁烟的理由，中心要明确，避免使用错误的语法。
正文：
We can see such signs as “No Smoking” in some public places, which is a kind of measure taken to ban smoking in public places. However, concerning about this measures, different people hold divergent opinions. The smokers protest against that it is a kind of action to deprive of their free right, while the non-smokers are in favor of banning smoking in public places.
在一些公共场所我们可以看到像“禁止吸烟”这一类的标志，这都是在公共场所禁烟的方法。然而，对于这种措施，不同的人有不同的想法。吸烟者认为这是剥夺他们自由权的行为，而不吸烟的人则是支持在公共场所禁止吸烟。
In my opinion, I am inclined to support the latter one—smoking should be banned in public places. There are reasons accounting for my point. For one thing, people will be harmed by the second-hand smoking if someone smokes in public places, especially the infants and children.
在我看来，我更倾向于支持后者——在公共场所应该禁止吸烟。我有我的原因。一方面，如果有人在公共场所吸烟的话，人们就会受到二手烟的伤害，特别是婴儿和儿童。
For another, banning smoking in public places is also beneficial to the smokers. If they are banned to smoke in public places, they will restrain themselves from smoking and smoke less. In the meantime, it is a contribution to reduce the air pollution.
另一方面，在公共场所禁止吸烟对于吸烟者也是有好处的。如果在公共场所禁止吸烟，他们就会被限制吸烟，少抽烟。同时，对于减少空气污染也是有贡献的。
Therefore, I advocate that smoking in public places should be banned so that we can breathe the fresh air and suffer less from the second-hand smoking. Let’s work together to create and sustain out green and fresh environment.
因此，我主张在公共场所禁止吸烟，这样我们才可以呼吸到新鲜的空气，少吸二手烟。让我们一起共创造、维持绿色清新的环境。
