题目列表(包括答案和解析)
Bats are the only flying mammals(哺乳动物) in the world. They can't see very well. It was long believed that all bats are blind. “Blind as a bat” is often heard.
Yet they have no trouble flying on the darkest nights and finding their way around very well. How can bats fly and see at night? They fly by radar(雷达).
The bat's radar system(雷达系统) works the same way as the one that ships and planes use. As a bat flies through the air, he makes a sound that is too high for our ears to hear. When the sounds hit things, they come back. The bat's ears receive the messages. In this way they are able to tell the bats where the things are.
Bats go out to look for food at night. Some people have the bats as bad animals. In fact, they are useful animals.
