During their lifetime, it can be expected that of these 3,000 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 percent, smoking rates among youth have declined. While the decline is impressive, 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.1.

经过定位，答案在第一段的最后一句，该句大意是“因为吸烟而导致的死亡人数超过所有别的因素导致的死亡人数，不管这些死亡因素是不是自愿发生的。

”从这里可以看出，答案是B（和吸烟有关的疾病）。

2. 本题问“每天有多少青少年会上烟瘾？”这也是细节题，中心词是“regular smoker”。

经过定位，答案在第一段的第一句话，该句明确指出每天有超过3000名青少年会上烟瘾。

答案是D。

3. 本题问“作者在第三段中所说的…dropout‟是什么意思？”这是词汇题，解题思路是找到该词所在的句子及其前后句。

第三段的大意是“首先，在过去几年中，青少年吸烟率没有降低多少。

其次，在20世纪70年代晚期，高中高年级男生的吸烟率比高中高年级女生的吸烟率要高将近10%。

目前这个数字正在往相反的方向转变。

第三，有几个近期的研究表明高中的dropouts吸烟率极高，达到75%。

”再看选项的意思，A的意思是“考试不及格的学生”，B的意思是“离开学校的学生”，C 的意思是“迷路的学生”，D的意思是“被赶出学校的学生”。
