Passage Two

听力原文

        There’s an endless amount of scientific data proving that dogs can develop strong bonds with their owners. People aren’t kidding when they say they “love” their dog or their dog “loves” them. (19) But we’re rather ignorant about the nature of the relationships that form between dogs. In an effort to understand the matter further, I spoke with Dr. Marc Bekoff a researcher and former professor of animal behavior. (20) The doctor’s response to the question of whether or not dogs can fall in love like humans do was a straight “of course”. He went on to say that if love is defined as a long-term commitment—meaning dogs seek one another out when they’re apart, they’re happy when they’re reunited, they protect one another, they feed one another, they raise their children together—then, of course, dogs love each other. Now our furry friends don’t really experience “romantic” love, like in the movies, but they can form deep and lasting bonds with their fellow dogs as well as humans. (21) In fact, evidence shows that most dogs stay with one partner their whole lives. In actuality, love between dogs can be even more intimate than human relationships. When they interact, they aren’t afraid to smell each other and will express themselves clearly and honestly. Once again, it seems we have a lot to learn from dogs.

20. What does Dr. Mark Bekoff say about dogs?

解析：D。录音中间提到，作者在问到狗是否可以像人类一样相爱的时候，博士直截了当地回答“当然”。由此可知，贝科夫博士认为狗可以像人类一样相爱，故D项正确。C项利用录音原词respond和questions作干扰，但录音中说的是Marc博士所作回应，并非狗对人类的回应，故错误。A和B两项在文中均未提及，故排除。
