网考网解析：
试题答案： 答案解析：According to the lecture, birds in the natural world have better vision than human beings because of the position of their eyes. Some birds, like hawks, have eyes on the front of their skull, so this eye position allows them to judge distance and change speed accurately when hunting for food. Other birds, like ducks, have eyes on either side of the skull. With this kind of eye position, they are more alert towards approaching enemies and can avoid danger. [听力原文] W: Look around you; you probably think you see the world pretty clearly. It is hard for us to imagine an animal like a bird seeing better than we do, but many do. Birds depend on vision to hunt prey and avoid predators. The positions of their eyes are extremely important for their survival. The position of a bird’s eyes has two types of configurations, according to biologists. The first type of position is where the eyes are in the front of the skull, just like human eyes. Birds with such an eye position have accurate sight to find food. For example, hawks can see a tiny mouse from miles away. They can judge distance and change speed to accurately catch prey. Other birds’ eyes are placed on either side of the skull. This type of position enables birds to watch approaching predators from both sides and avoid attacks from predators. Ducks are a kind of bird with such an eye position. This allows them to always be cautious towards any approaching dangers from predators like a fox, and avoid their bites at the last second. document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
