So you think you know your dog. But how well does your dog know you? 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. Dogs are very mindful of sound. When dog owners shout or speak in a strong, unkind voice, dogs often act ashamed 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 praise from one of blame. Researchers at the University of Veterinary Medicine, Vienna performed a series of experiments. They taught dogs to recognize facial expressions. 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. They were also shown the left half of the faces used in training. Corsin Muller led the study. "We were really speaking, do they realize that smiling eyes have the same meaning as a smiling mouth, or angry eyes have the same meaning as an angry mouth? And it turned out that they really did perform very well in these research experiments." Once the dogs learned to recognize which image was happy or angry, they could easily find the same expressions in pictures of any face. Corsin Muller says future studies will try to show whether dogs can learn the meaning of facial expressions--for example, whether a frown shows that someone is angry. In the experiments, researchers found the dogs were slower to link a reward, or prize, with recognition of the angry face. This suggested that dogs had an idea people with angry faces were best avoided. Hearing its owner's strong, unkind voice, a dog is likely to _ . A) jump happily B) act excitedly C) escape quietly D) shout loudly

Last weekend marked one of the nicest days so far this spring. It was warm with a tiny wind, the sun streamed through lightweight sweaters to warm the skin; the male choir was warming up, and the students were moving around the lawn behind the huge crowd of six-thousand-plus observers. With all of the parents, sisters, brothers, grandparents, aunts and uncles, the state university was a center of activity. My nephew was going to receive his bachelor's degree. Who would have guessed that four years would go by so quickly? As the crowd of freshly polished candidates wandered, joked, hugged and chatted behind the bleachers , I heard several cell phones ring. There were several casual conversations going on with the accompanying giggles of the not-quite-mature students, but then one conversation in particular caught my attention: "Yes, Grandma, I'm really graduating. I can't believe it, either! I never thought I'd be here today, you know? Really! Like, I know it! Yes, it's a very special day. Oh, what did the doctor say? He did? I know, Gran... I know you wanted to come... It's okay... No, really, please don't cry...It's a very happy day, you know? "Hold on, we're lining up okay, all set... yes, the center aisle ... the grass is awesome! Smells really good, too... Oh wow, they've got like a million balloons they're going to release! Yes, Kelly's here... Okay, I'll give her your love... here we go! Gran, I'm graduating! "Love you, too, Gran. I'm so glad you could be here with me!" And somehow, my initial dislike at the use of cell phones and the casual conservations during such a serious occasion left me. For these little representatives of modern technology had joined a young woman and her fond Gran to share a very special moment in time. Where did the story take place? A) At an open-air theater. B) At a traditional festival. C) At a graduation ceremony D) At an important sports game.
