  答案:D;A;A;A;B

  解析:

  (1)这是道细节题,据文章最后一段可以确定正确答案为D。(2)本题要求确定作者的态度。综合分析全文的大意,文章一天始就很客观的阐述了居住山区的人似乎活得都很长,下面几个段落主要分析了长寿的原因,语气规范,不难推知作者对此印象比较深刻,故答案为A。(3)该题为词语释义题。根据上下文,显然passageoftime的意思应为“随着时间推迟推移”,故答案为A。(4)这是道细节题。根据文章第三段的内容,作者主要给我们一个真实的例子来说明长寿人生活方式,故答案为A。(5)本题要求确定文章主题。阅读全文,可知作者在文章中从几个方面详细地描述了在某些社会人长寿的原因,并举了几个例子说明空气、劳动、饮食、基因是长寿的重要原因。结合文章大意的分析,可确定答案为B。
