41.
Today ,as in every other day of the year ,more than 3000 U.S.adolescents（青年人） will smoke their first cigarette on their way to becoming regular smokers as adults.During their lifetime,it can be expected that of these 3000 about 23 will be murdered,30 will die in traffic accidents,and nearly 750 will be killed by a smoking-related disease.The number of deaths attributed to cigarette smoking outweighs all other factors,whether voluntary or involuntary,as a cause of death.
Since the late 1970s,when daily smoking among high school seniors reached 30 percents,smoking rates among youth have declined.While the decline is impressive（印象深刻的）,several important issues must be raised.
First,in the past several years,smoking rates among youth have declined very little.Second,in the late 1970s,smoking among male high school seniors exceeded that among female by nearly 10 percent.The statistic is reversing.Third ,several recent studies have indicate high school dropouts have excessively high smoking rates,as much as 75 percent .
Finally,though significant declines in adolescent smoking have occurred in the past decade,no definite reasons for the decline exist.Within this context,the National Cancer Institute (NCI) began its current effort to determine the most effective measures to reduce smoking levels among youth.
