reason why people keep a dog has changed.In the old days people used to train dogs to protectthemselves against attacks by other beasts.And later they came to realize that a dog was notonly useful for protection but willing to obey his master.For example,when people used dogsfor hunting,the dogs wouldn't eat what was caught without permission.But now people in a cityneed not protect themselves against attacks from animals.Why do they keep dogs then?Somepeople keep dogs to protect themselves from thieves.But the most important reason is forcompanionship.For a child,a dog is his best friend when he has no friends to play with.Foryoung couples,a dog is their child when they have no children.For old couples,a dog is also theirchild when their real children have grown up.So the main reason why people keep dogs haschanged from protection to friendship.英语参考答案与评分细则第5页（共2页）
