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.

　　The undersea world is very beautiful. Now more and more people want to dive in the water to find the secrets there. Scuba diving is a new sport today. It can take you into a wonderful undersea world.

　　You will find many strange animals in the sea. Some are as large as a school bus. Many sea animals give out light in the dark and some have sharp teeth.

　　Dick was a clever boy, but his parents were poor, so he had to work in his spare(空闲) time and during his holidays to pay for his education. In spite of this, he managed to get to the university, but it was so expensive to study there that during the holidays he found it necessary(必要的) to get two jobs at the same time so as to earn enough money to pay for his studies.

　　One summer he managed to get a job in a butcher's shop during the daytime, and another in a hospital at night. In the shop, he learnt to cut meat up quite nicely, so the butcher often left him to do all the serving while he went into a room behind the shop to do the accounts(账目). In the hospital, on the other hand, he was, of course, allowed to do only the simplest jobs, like helping to lift people and to carry them from one part of the hospital to another. Both at the butcher's shop and at the hospital, Dick had to wear white clothes.

　　One evening at the hospital, Dick had to help to carry a woman from her bed to the place where she was to have an operation. The woman was already feeling frightened at the thought of the operation before he came to get her, but when she saw Dick, that finished her.

　　“No! No! ” she cried, “Not my butcher! I won't be operated on by my butcher!” and fainted away.
