2.You think you know your dog.(36)C She probably recognizes you when she sees you.But can a dog tell by simply looking at you whether you have a happy or an angry expression on your face?Researchers in Austria have taught pet dogs to know the difference.
(37)A When dog owners shout or speak in a strong,sharp voice,dogs often act guiltily and quietly move away from the area.
Recently,researchers found that dogs can look at our faces,and tell the difference between a smile and a frown.The animals were able to recognize a look of approval from one of disapproval.Researchers at the University of Veterinary Medicine performed a series of experiments.(38)F They showed the dogs two pictures of either the upper or lower half of a person's face.On one picture,the person looked happy.The other appeared angry.The dogs were then shown images of the eyes or mouths of people they had never seen before.
(39)D Once the dogs learned to recognize which image was happy or angry,they could easily identify the same expressions in pictures of any face.Future studies will try to show whether dogs can learn the meaning of facial expressions.(40)G
The researchers'findings were published in the journal Current Biology.They provide the first solid evidence that humans are not the only species that can read the body language of another species.

38.F.推理判斷題.由下一句"They showed the dogs two pictures of either the upper or lower half of a person's face."可知,他們應該是教狗識別面部表情,故應選F.
39.D.推理判斷題.由下一句"Once the dogs learned to recognize which image was happy or angry,they could easily identify the same expressions in pictures of any face."可知,這里仍然是教狗識別面部表情的,故應選D.
40.G.推理判斷題.由下一句"The researchers'findings were published in the journal Current Biology."可知,這里應該是舉例說明研究者的發(fā)現(xiàn),故應選G.
