Question

It seems that there’s a good reason why dogs are always seen as man’s best friend. Scientists have found that dogs are the only animals that can read emotion(情感)in faces much like humans. The finding suggests that like an understanding friend, dogs can see if we are happy, sad, pleased or angry.
When humans look at a new face, their eyes usually look across the left, falling on the right hand side of the person’s face first. A possible reason for this is that the right side of the human face is better at expressing emotions.
Scientists have now shown that pet dogs also have “left gaze bias(左视偏好)”, but only when looking at human faces. No other animal has been known to do like this before. Dr. Kun Guo showed 17 dogs pictures of human, dog and monkey faces as well as something else with his team. The dogs’ eyes and heads show a strong left gaze bias when the animals see human faces. But this did not happen when they were shown other pictures, including those of dogs.
Guo suggests that over thousands of years living with humans, dogs may have developed the left gaze bias as a way to guess our emotions.
“Recent studies show that the right side of our faces can express emotions better than the left. If true, then it makes sense for dogs and humans to see the right hand side of a face first.”

解析试题分析：这篇短文主要介绍了狗是唯一能读懂人类脸上情感的动物，它是人类最好的朋友之一。科学家们发现狗经过与人类几千年来的生活，狗像人类一样有左视偏见。
【小题1】细节理解题。根据短文第一段The finding suggests that like an understanding friend, dogs can see if we are happy, sad, pleased or angry.，故选B。
【小题2】推理判断题。根据第四段Guo suggests that over thousands of years living with humans, dogs may have developed the left gaze bias as a way to guess our emotions.可知与人类几千年来的生活, 狗可能已经开发出左视偏好来猜测我们的情绪，故可推测左视偏好使狗和人相处融洽，故选A。
