【题目】 The world is so colorful in our eyes. But does it look the same through the eyes of animals?
Animals live a different life from us humans. They have different needs. So their eyesight(视力) is special in all kinds of ways.
| Dogs have fewer color-detecting cells (色彩感知细胞) than us and they can only see blue, brown and yellow. So when you go out with your pet dog, you’d better wear blue or yellow clothes so that your dog can follow you more easily. |
| Jumping spiders have eight pairs of eyes and they can see more colors than humans. Not only that, they can see ultraviolet light (紫外线), so they will see things clearer than us. |
| Mice can move one eye in different directions while keeping the other eye still. It’s better to see their enemies (敌人). They can’t see as many colors as us. It’s not necessary because they mostly come out at night. |
| Horses are very tall and their eyes are on either side of the heads, so they can see wider than humans. However, a horse has a blind point in front of its nose. They can see green and blue, but most of the time they see grey. |
