题目分析：你昨天刷了几次牙？你昨天洗了几次手？刷了几次厕所？你多久消一次毒？这些调查报告有助于我们了解一下关于个人卫生和健康的现状。

小题1:细节理解题。根据第一项调查中“A full 33% of seniors brush their teeth only once a day.”可知，大约有三分之一的美国老年人一天只刷一次牙。

小题2:细节理解题。根据第二项调查中“…4 times a day—half of the number doctors recommend”可知，四次是医生建议次数的一半，也就是说，医生建议老年人每天洗八次手，故选D。

小题3:细节理解题。根据文章倒数第二句“Do you know it is not your toilet but your kitchen sponge that can carry more germs than anything else？”可知，厨房里的海绵比卫生间带有的细菌还要多。
