问题                                                   A New Study Says Your Stress Can Spread to Your Dog
         Research shows that most dog owners find their pets to be great stress busters. Curling up on the couch with your pug or playing catch with your labradoodle is a great way to unwind and let the cares of the day slip away. New science has some bad news for dog owners. Dogs might ease your stress, but they can also catch it.
         It’s an old joke that dogs resemble their owners, but according to this new study out of Linkǒ ping University in Sweden, it’s actually true in one less funny way: Stressed out owners have stressed out dogs.
         To figure this out, the researchers took hair samples from 25 border collies and 33 Shetland sheepdogs, as well as their female owners. For both humans and dogs, hair records the level of the stress hormone Cortisol in the body over time. So by analyzing these hairs, the team could figure out just how much stress both the owners and their pets were under long-term.
         The study found the stress levels of the dogs and their owners matched up: Higher levels of stress among owners showed up as higher levels of stress in their dogs. The effect was even more pronounced if the dog was female or if it took part in agility competitions with its owner.
         Previous research has found that Cortisol in humans and their dogs can rise together in the short-term, especially when competing. But this finding was something new. "This is the first time we’ve seen a long-term synchronization in stress levels between members of two different species. We haven’t seen this between humans and dogs before," lead researcher Lina Roth told The Guardian.
The author writes the first paragraph in order to___________.
选项 A、attract attentions by highlighting the differences in the study of the relationship between humans and pets
B、summarize the previous findings
C、highlight the finding of this research and lead the theme
D、highlight the close relationship between pets and people
答案C
解析 推断题。题干：作者写第一段的目的是第一段先点明宠物是很好的减压者，并用生动形象的例子列举了宠物帮助人们减压的方法，之后话锋一转，有新研究表明狗能减压的同时也会被主人传染压力，由此引出文章的主题。故本题选C项“强调新的研究发现，并引出文章主题”。A项“通过强调人类和宠物之间关系研究的差异来吸引注意”，根据文章可知，研究主要是说明人的压力与宠物狗的压力之间的关系，并不是在强调人与狗的关系，所以A项表述错误；B项“总结之前的发现”，第一段中不仅提到之前的研究发现，也提到了新的研究；D项“强调宠物和人之间的亲密关系”不能完全概括第一段。
