题目：
Zhang Li lies in bed sadly. The 24-year-old young man lost his right leg because of a blood disease (血液病). The doctor said that his 10 years of smoking had caused the disease.
“I first smoked a cigarette when I was in Junior 3. It made me feel like a man and I thought it looked cool. Now I know I was really wrong,” said Zhang.
According to the 2008 China Tobacco Control report (中国烟草控制报告), 130 million young people who are under 18 years old have tried smoking. Fifteen million of them are addicted (上瘾的).
The report came out on May 31, World No-Smoking Day. (83)It also found that nearly 68% of teenage smokers smoked their first cigarette before the age of 13. Those living in big cities started even earlier.
“Some tobacco companies try to make cigarettes cool and attractive. It’s just to make money,” said Yang Gonghuan, a doctor. In fact, smoking is one of the top killers in China. Each year 1 million people die from smoking-related (与吸烟有关的) diseases. Smoking causes illnesses like lung cancer and heart disease.Doctors say that the younger a person starts smoking, the worse it will be. If a person starts smoking as a teenager, he or she may live twenty-two years less than non-smokers.
