　　(2016·太原市第二学段测评)It may seem crazy when you watch your dog bury his bone, only to dig it up a day or two later.__1__It is simply in their nature. For thousands of years, dogs have buried their bones. The practice itself started long before dogs were even pets when their ancestors had to bury bones to survive.

　　__2__If they were able to find meat and bones, dogs became very protective of them. To keep other dogs and animals from stealing their meat and bones, dogs would bury them in the ground. When it was time for the next meal, they would dig up their bones and enjoy them again.

　　Although most dogs have plenty of food to eat today, their instincts still tell them to bury their bones. Some dogs hide more than one at once, burying one and digging up another.__3__

　　So how do dogs decide where to bury their bones? A dog cannot bury a bone just anywhere.__4__This involves using his nose to sniff out a spot that is free from predators. Often it is near a tree or a large rock. Once the dog finds the satisfying spot, he uses his front paws to dig the hole, drops in the bone and covers up the hole to protect his treasure.
