It has been estimated that smokers have 高考made up half of the population in China. And the smokers are becoming younger and younger, even ineluding 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.
