题目内容
6.In our daily life,humans can make use of an animal's homing instinct.Pigeons,for example have been used to carry messages or letters to the battles in times of war.Nowadays some people join in the Pigeon Association with the pigeons they have trained because they
look on pigeon racing as a hobby and they even bet money on which pigeon would win the race organized by the association.
There are many interesting stories of the homing instinct at work.In the USA a cat traveled 1,360kilometers back to its old home after the owners moved,taking nearly a year over the journey.When we lose our cat,we usually find her again near the house where she was born.We have a pond in the garden where the frogs come back every year.I even heard a dog which was injured by a car managed to take itself to a doctor who cares for animals!
There are other wonderful stories about the homing instinct~But how do these animals find their way home?They don't have satellite guidance with them,they can't read maps and,as far as we know,they can't ask each other for directions.It seems that some animals,such as salmons,use their sense of smell to take them back to the place where they were born.Other animals such as birds and bees may use the sun,the stars and the moon to help them find their way.There is a theory that some animals have magnetic(磁的) cells in their brain which help them to find their way.As far as cats are concerned,nobody really knows how their homing instinct works and I am sure cats are never going to give away their secrets.
Finally,a joke about the homing instinct:
Question:What will you get if you cross(杂交) a pigeon with a parrot?
Answer:A bird which can stop and ask the way home!
