句式:

(among the groups of various economic activities,)(介词结构做状语)

【the retired】(主语) 【read】(谓语)

【newspapers, weeklies and books】(宾语) (in the highest ratio)(状语),

and ratio is 50%.

1—among the groups of various economic activities:在形形色色的经济活动中

among为介词,表示“在……之间”

economic activities 经济活动

2—the retired: 退休人士. the + adj. 表示一类人.

newspaper, weeklies, books是并列的宾语.

这句话说:退休人士阅读比例最高的就是报纸、周刊、书籍.这个比例达到了50%之多.
