11．You may laugh when you see dog owners talk to their pets as though they were human．Although dogs cannot speak a human language，they seem to understand how you feel．Sounds strange？Now scientists have found that dog and human brains deal with sound and emotion（情感）in a similar way．This may help to explain the language problem．
To compare human and dog brains，a scientist called Attila Antics and his team tested 11dogs and 22humans．Both group listened to almost 200dogs and human sounds．From crying to laughter and playful barking（吠）．At the same time，the team scanned（扫描）both group's brain activity．
The scientists found that a similar part in both brains was activated（激活）when animals ad people heard human voices and emotional sounds，such as crying and laughter．Also，emotional dog voices，such as angry barking also caused a similar action from human and dog volunteers．
We know very well that dogs are good at tuning（和..协调）into the feeling of their owners，and we know a good dog owner can find emotional changes in their dog．But we now begin to understand that this similarity may help to explain this can be．So next time when you see dog owners talk to their pets，don't laugh．Maybe they are really"talking"．

| Dogs feel human emotion | |
| The strange thing | When dog owners talk to their pets，dogs seem to understand their owners'（91）feelings |
| The steps of the experiment | A scientist and his team tested dogs and humans to（ 92）compare human with dog brain． The two groups listened to different sounds such as crying，laughing and （93）playful barking After the team watched their brain activity，they found their reactions（反应）were in a （94）similar area in both brains |
| The （95）result of the experiment | It's very similar dog and human brains to deal with sound and emotion |
