Smoking is harmful 吸烟有害

　　It has been estimated that smokers have made up half of the population in China. And the smokers are becoming younger and younger, even including some middle school students.
　　Nowadays more and more people have realized smoking can do harm to people'shealth. However, some people still enjoy smoking. Why? Because some of them think it is a kind of fashion, some think it is of great fun and others, think that smoking can refresh themselves.
　　In fact, smoking is a bad habit. It can cause a lot of diseases. Meanwhile smoking is a waste of money. Besides, careless smokers may cause dangerous fires.
　　Smoking is harmful and it is not only bad for smokers themselves, but also bad for non-smokers.
　　Therefore, I hope all the smokers can give up smoking for themselves and also for the people around them.

据估计，在中国吸烟者占一半的人口。而且烟民的年龄越来越年轻，甚至一些中学生也开始吸烟。
现在越来越多的人已经认识到吸烟有害人体健康。然而，一些人仍然享受吸烟。为什么？一些人认为抽烟是一种时髦，一些人认为它是非常有趣还有其他人认为吸烟可以提神。
事实上，吸烟是一种坏习惯。它能导致很多疾病。同时，吸烟很浪费金钱。此外，粗心的烟民还可能引起火灾。
吸烟是有害的，它不仅有害烟民，而且也会伤害不吸烟者。
因此，我希望所有的烟民不仅为了自己和还有周围的人戒烟。
