英语翻译
Like other animals,dogs see best when things move.The animals they hunt seem to know this.A hunted rabbit or deer will “freeze“.Then the dog may not see it at all.Birds can see colour.They need to,because they fly and need to find places to land.Colour helps them judge bugs(小虫) in the air or the light on branches.
Some birds see things even better than you do.The birds that eat bugs can see them from far away.And even a very young bird can see a hawk high in the sky.So sharp eyes and sense of colour help birds find food and also help them find where their enemies are.

颜色能帮助你辨别东西.但只有人类、部分猴子和猿类能辨别颜色.对于很多哺乳动物,例如狗,世界就像黑白照片.狗主要靠听觉和嗅觉捕获食物.
和其他动物一样,狗在物体移动时看得最清晰.动物在被追捕时都知道这一点并加以运用.兔子或鹿在被追捕时会呈现“冻结”状态,此时狗几乎看不到它们.鸟类也能分辨颜色,它们必须如此因为它们飞行在空中,需要找地方歇息.颜色能帮助它们判断空中的小虫或树枝上的光.
某些鸟类的视觉甚至比人类好.吃小虫的鸟能发现很远处的小虫.即使是很年幼的小鸟能看到高空中鹰的踪影.因此,锐利的颜色和对颜色的分辨能力能帮鸟儿找到食物并发现敌人的所在.
