科学英语：汪星人看得懂电视上的图像.docxVIP

Domestic dogs can perceive images on television similarly to the way we do, and they are intelligent enough to recognize onscreen images of animals as they would in real life -- even animals theyve never seen before -- and to recognize TV dog sounds, like barking.家犬和我们一样，看得懂电视上的图像。它们还聪明到能辩得出画面上的动物——无论他们是否在现实中见过这种动物——它们还能辨认出电视里传来的犬吠声。A 2013 study published in the journal Animal Cognition showed that dogs could identify images of other dogs among pictures of humans and other animals, using their visual sense alone.However, there are some differences between ourselves and mans best friend -- for one, dogs eyes register images more quickly than do ours. So older television sets, which show fewer frames per second than modern televisions, would appear to a dog to be flickering1 like a 1920s movie, said Nicholas Dodman, a veterinary behaviorist at Tufts University, in Massachusetts.Dogs also have dichromatic vision, which means they see a range of two primary colors, yellow and blue. Human vision is trichromatic, so we see the full range of colors, according to Binghamton Universitys Ask a Scientist web page.DogTV, an HDTV cable channel designed for dogs, interests canines2 because HDTV has a much higher number of frames per second and is specially3 colored to accommodate dogs dichromatic vision, said Dodman, who is the channels chief scientist.DogTV has modes for relaxation4, which shows images like dogs chilling out in a grassy5 field; stimulation6, which depicts7 scenes like dogs surfing in southern California; and exposure which shows things like a dog reacting to a ringing doorbell and obeying commands to acclimate8 them to such situations at home.词汇解析：1 flickering adj.闪烁的，摇曳的，一闪一闪的参考例句：The crisp autumn wind is flickering away. 清爽的秋风正在吹拂。The lights keep flickering. 灯光忽明忽暗。2 canines n.犬齿( canine的名词复数 )；犬牙；犬科动物参考例句：For example, the teeth are more primitive.
