狗狗能讀懂你的喜怒哀樂

You pet dog is clever. When you are sad，it comes to sit on your feet. Does it really know your feeling（情緒）？ Scientists（科學(xué)家） in Hungary（匈牙利） said yes.

The scientists tested（測試） 11 dogs. The dogs listened to different sounds from people. Some were laughing. Some were crying. When the dogs listened to sounds of laughing，their brains（大腦） became more active（活躍的）.
