【回答】

篇章导读：本文是一篇说明文。文章介绍了跑步的好处——帮助人们延年益寿。

1．longer　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。根据空格后的than可知用比较级，故填longer。

2．to see　考查非谓语动词。你不必跑得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。

3．dying　考查非谓语动词。你也许喝酒、吸烟或超重，但仍然可以通过跑步减少早亡的风险。此处of是介词，其后用动名词。故填dying。

4．is　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，用一般现在时。故填is。

5．than　考查比较句型。根据空格前的more effective可知，此处填than。

6．that/which　考查定语从句的引导词。此处a study是先行词，指物，且关系词在定语从句中作主语，故填that或which。

7．causes　考查名词的复数。一项研究表明，仅仅每天5到10分钟的跑步，就能降低各种原因导致的心脏病和早亡的风险。根据句意可知用复数形式，故填causes。
