Bats are the only flying mammals in the world. They can't see very well. It was long believed, and still is in many places, that all bats are blind. “Blind as a bat” is often heard. Yet they have no trouble flying in the darkest nights and finding their way around very well. How can bats fly and see at night? They fly by radar. The bat's radar system 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. If the sounds hit things they come back. The bat's ears receive the messages. In this way they are able to tell the bat where the things are. Bats go out to look for food at night. In the daytime they hang in some dark places. Some people have the bats as bad animals. In fact they are useful animals.

Shane has no sense of direction. His friends often make fun of him. They say he needs a map to find the bathroom in his own house. He gets lost every time he goes shopping. Every street looks the same, and he quickly forgets which way to go. Sometimes he has to take a taxi home because he cannot remember the way to his house.

Shane watches a lot of films and reads a lot of books about animals. Each bird knows which way is south. Bats (蝙蝠) can fly at night and find their way with their ears.
