吸煙有害是每個人都知道的道理 。“世界無煙日”馬上就要來了。在這個日子來臨之際，作為中學生的你一定有自己的想法吧。

　　No Smoking Day is an annual health awareness day in the United Kingdom that helps smokers that want to quit smoking. The first No Smoking Day was on "Ash Wednesday" in 1984 and it now takes place on the second Wednesday in March. The campaign is now in its 24th year and is a firm fixture in the UK calendar because of its continuing success. On No Smoking Day 2006 1.5 million smokers made a quit attempt and millions more used the Day to take a step towards stopping smoking.

　　The campaign is run by a charity of the same name, which is based in London and has four full-time staff. The charity is funded by a coalition of governmental and voluntary sector organisations with an interest in health.

　　A survey about smokers in a middle school tells that although 90% of all students never smoke, 3% of them often smoke and 7% sometimes do. In other words, 10% of the students smoke. That’s terrible.

　　As we know, smoking is harmful to our health. Every year, thousands of people lose their lives because of it. Smoking not only does harm to your health, but also wastes money. Because, a fire may be caused by cigarette ends. It’s a pity to learn that one ends in death by smoking.

　　In all, smoking is so dangerous that we should keep away from it.
