But how can we find out whether animals can see color when they can’t tell us? Scientists have done many experiments to get the answer. The bee has been the subject of hundreds of these tests, because we have been curious to know whether the bee tells flowers apart by their colors. In one of those tests, a bit of syrup was put in front of a blue card, and no syrup in front of a red card. After a while, the bees would e to the blue card, no matter where it was placed, and even if it had no syrup in front of it. This proved they could tell colors apart. The animal that is probably closest of all to man as a friend, the dog, is colorblind! So far all experiments that have been done prove that the dog can’t tell one color from another. Many times when we think the dog is responding to a color, he is really responding to some other clue or sign—smell, size, shape. Dog lovers should not be too disappointed by this because the dog’s sense of smell is so great that it probably pensates for the inability to see in color. The reason for colorblindness in some animals is connected with the fact that most of them hunt by night and don’t depend on color, and also that they themselves are usually dull in color, so it isn’t important in their lives. 題目 31 of 50 得分It’s difficult for humans to imagine that ________. cannot see all colors animals have bad eyesight animals are colorblind are colorblind答案關(guān)鍵: C題目 32 of 50 得分Scientists have found that bees can see colors by ________. bees natural habits extremely curious about bees hundreds of tests involving bees bees’ behavior around flowers答案關(guān)鍵: C題目 33 of 50 得分In one test involving bees, the bees ________. to always go to a blue card only attracted to syrup to both red and blue cards not see the difference between red and blue答案關(guān)鍵: A題目 34 of 50 得分According to the passage, which of these statements is true? can sometimes respond to colors. lovers are sometimes disappointed by their pets. dog’s ability to smell is very good. is inconvenient for dogs to be colorblind.答案關(guān)鍵: A題目 35 of 50 得分One reason that some animals are colorblind is that ________. eyesight is very poor sleep during the day don’t depend on light don’t rely on color答案關(guān)鍵: D大項 4 of 6 Reading Comprehension (2) 得分Have you ever sudd
