Question

    Dog owners walked about 23minues longer each day than non-dog owners In a new study, dog owners took 2,760 additional seps—compared to people who didn’t have a dog at home. Bu here’s the real good news: That extra exercise was done at a moderate（适度的）pace, which means it could help adults meet their recommended weekly totals for physical activity.

The research, published in BMC Public Health, focused on adults 65 and older, who tend to be less active than younger people. The study included 43 dog owners and 43 non-dog owners, all of whom were monitored continuously for three week-long periods. When they compared the two groups, the researchers found that dog ownership was associated with a large, potentially health-improving effect.

Dog owners walked about 23 minutes longer each day than non-dog owners, 119 minutes versus 96 minutes on average. They also took an additional 2,760 steps, and had eight fewer continuous periods of sitting down. Most of that extra walking was done at moderate pace, defined as 100 or more steps a minute. Dog owners walked at this pace for 32 minutes a day, versus just 11 minutes a day for non-dog owners.

The World Health Organization（WHO）recommends that adults get at least 150 minutes of physical activity a week. This increased walking time alone could just about satisfy that requirement, say the researchers—so it makes total sense that 87 percent of dog owners in the study met these guidelines, versus just 47 percent of non-dog owners.

Co-author Nancy Gee says that pet ownership may help older adults get more activity or maintain their current activity level for a longer period of time. “This could improve their chances of a better quality of life, improved or maintained cognition（认知）, and perhaps, even overall longevity（寿命）,”she said.

Here at Health, we’ ll add that caring for pets has been shown to have plenty of other physical and mental health benefits, as well. As animal lovers ourselves, we’ re happy to add one more to the list.

【解析】

本文是一篇说明文。文章通过一个对比研究，得出有狗的人要比没有狗的老年人得到更多锻炼，进而提出老年人养宠物有助于他们的健康生活。

1.

细节理解题。由第二段“The research, published in BMC Public Health, focused on adults 65 and older, who tend to be less active than younger people. ”可知，这项研究主要研究65岁及以上的人群。因为这些人要比年轻人的活动量少。所以研究主要是针对老年人的。故选A项。

2.

推理判断题。第二段提到这次研究对43位有狗的人和43位没有狗的人进行比较。第三段用一些具体数字具体说明了比较结果。即前者比后者每天多走23分钟。有狗的人多走2,760步，比后者少坐8次。多走的这些步数步伐适中，一分钟100或100多步。有狗的人以这种速度每天走32分钟，没狗的人只走11分钟。所以作者主要用数据对比，告诉我们研究的结果。故选A项。

3.

推理判断题。由倒数第二段“Co-author Nancy Gee says that pet ownership may help older adults get more activity or maintain their current activity level for a longer period of time. “This could improve their chances of a better quality of life, improved or maintained cognition（认知）, and perhaps, even overall longevity（寿命）,”she said.”可知，Nancy Gee认为养宠物对于老年人来讲可以使他们获得更多锻炼，让他们长时间保持锻炼的状态。也可以提高他们的生活质量，改善认知，甚至可延长他们的寿命。老年人可以有一个更加健康的生活。故选C项。

4.

主旨大意题。第一段Dog owners walked about 23minues longer each day than non-dog owners （养狗的人比不养狗的人每天多走23分钟）是全文的主题句，结合全文内容，可知这篇文章通过一个对比研究，得出有狗的人要比没有狗的老年人得到更多锻炼，进而提出老年人养宠物有助于他们的健康生活。只有D项“养狗的人多走路”符合文意。故选D项。
