问题 It is easy to determine whether smoking is hazardous.
Smoking reduces one’s life expectancy.
选项 A、Right
B、Wrong
C、Not mentioned
答案A
解析 借助常识判断该句说法正确，因此答案可能是正确或没提到(提示：违背我们常识和 /或背景知识的内容往往都是错误的)。利用题干中life expectancy(新信息)作为答案线索词，直接在文章中找到答案相关句：Research teams have conducted studies that show beyond all reasonable doubt that tobacco smoking is associated with a shortened life expectancy．该句说“研究小组所做出的研究结果都表明吸烟与寿命的缩短有关，这些研究结果不容质疑。”该句内容与问题句的说法一致，因此答案为正确。
