Question

任务型阅读。

　　Color helps you see things．But man and some monkeys and apes(猿)are the only mammals(哺乳动物)that can see color．To any other mammal, such as the dog ,the world looks like a black and white photo．Dogs hunt mainly by listening and smelling．

　　Like other animals, dogs see best when things move．The animals they hunt seem to know this．A rabbit or deer will freeze when they find that they are being hunted．Then the dog may not see it at all．

　　Birds can see color．They need to ,because they fly and need to find place to land．Color helps them know how far the place is and what it is like so that they are able to catch flying things in the air or land on something they think safe．

　　Some birds see things even better than man do．The birds that eat bugs(飞虫)can see them from far away．And even a very young bird can see a house from high up in the sky．So good eyes and being able to see colors help birds find food and also help them find out if there are any animals that are dangerous to them．
