　　【解析】本文是一篇说明文。文章讲述了跑步的好处，它可以帮助人们延年益寿。
　　61. 考查副词的比较级。医学报告显示：经常跑步的人比不跑步的人多活3年。根据than可知用比较级，故填longer。
　　62. 考查不定式作目的状语。你不必跑地太快或时间太长就能看到它的好处。此处不定式作目的状语，故填to see。
　　63. 考查动名词。你也许喝酒、吸烟或超重，但仍然通过跑步会减少早亡的风险。此处of是介词，其后用动名词。故填dying。
　　64. 考查动词的时态。医学报告显示：跑步比散步、骑车和游泳更能有效地延长寿命。这里叙述的是一个事实，故用一般现在时。故填is。
　　65. 考查比较句型。跑步比散步、骑车和游泳更能有效地延长寿命。根据文章中的more effective可知此处填than。
　　点睛：本文比较难的一个题是10题。短语give it a try不容易想出来。give a try试试。Give sb sth； give sth to sb这些短语学生都很清楚。但give后加it或sth的形式，比较少见。高考复习要尽可能多的复习相关的短语，尤其是用的比较多，而课本中出现较少的短语。
