　　The dog has always been considered man’s best friend. Always noted for being particularly faithful in watching over children, he also has his place by the fireside, in the cow pasture, on the sheep range(放牧区), and beside the hunter in forest. He is easy to train, works hard, and often performs astonishing feats. And in the frozen polar regions he was once the principal motive power, before being lately displaced by the plane and helicopter.

　　Because he howls or whines in the presence of impending death, the dog was once thought to have supernatural powers and believed to be capable of seeing gods and ghosts invisible to men. Actually, the basis for these beliefs lies in the hound’s sensibility to people’s feelings and his superior hearing ability and sense of smell, which enable him to detect signs hidden from human observation. His record of saving lives is outstanding, for he often gives warning of fire and other dangers not noticed by his master.

　　The dog’s major contribution, however, has been to medical research. Both his diet and his structure are comparable to those of the human being, and so he has been the subject of countless demonstrations and experiments. Open heart surgery has been made possible largely because of the dog. But his sacrifice has repaid his own species as well by safeguarding it from rabies(狂犬病), distemper, and other diseases.

　　The strange close understanding between twins is a familiar enough phenomenon. Often they seem to understand each other and share each other’s emotions to such an extent that one suspects some kind of thought communication.

　　What is not so widely known is that this special relationship often acts as brake on twins’ intellectual development. As they are partly isolated in their own private world, twins communicate less with adults than do other children. The verbal ability of a four-year old twin is typically six months behind that of a non-twin. The problem can be particularly severe in an underprivileged family, a one parent family for example, where there is little stimulation for children anyway.

　　Such children, while capable of mutual comprehension in a private language, often remain incomprehensible to outsiders and thus at a severe educational disadvantage. The only solution to the problem, cruel though it may seem, is to separate the twins thus forcing them to acquire ordinary speech helped and guided by sympathetic parents and teachers.
