Animals perform many useful and entertaining jobs. Dogs
are particularly valuable guiding the blind, protecting property, 【1】______
finding lost people, and hunting criminals. Homes are used
in guarding herds, carrying people in lands where are no roads, 【2】______
and help farmers work in their land. Pigeons have long
been used to carry messages. People realize that although
animals may not have the same intelligence like human beings, 【3】______
they are smart to learn certain things. Training a dog to be 【4】______
a watchdog often produces unexpected results. Some dogs
quickly learn difference between unwanted people and 【5】______
friends. This is because their masters welcome friends
and invite them into their houses. Some clogs must always attack 【6】______
postman who comes to deliver letters. One explanation for
this behavior is that the postman comes to the house, 【7】______
he never enters the house. Therefore, the dog thinks
the postman is someone who is not welcome, but who keeps coming.
Masters of dogs who attack postmen can easily show the
dog that the postman is a friend and the dog does not need
to treat him as an enemy. A dog is quite ready to do that 【8】______
his master wishes. And a dog is always happy when he
is praised for understanding correctly.
Dogs can be taught to obey commands when the sound
of a word is connected to a certain act. Two important 【9】______
factors in teaching a dog to obey commands are: using
the same act, and moreover, teaching only one act at a time. 【10】______
Dogs can learn not only to sit, lie down, come, and stay
in a place when their masters go away, but also to jump, carry,
and fetch things. [br] 【M4】
