Man's Four-legged Friend原文
The sun was shining and it was warm.Robin,a shepherd,was lying on the grass,enjoying the beautiful sunshine.His guard,a sheepdog,was standing next to him,looking at the flock of sheep.
This is only a scene in a movie,but it does give us a real picture showing man’s relationship with dogs.For a long time in history,dogs were not only being raised to work as man’s guards,but they were also being trained to do many other jobs.Some were made to pull carts; others were bred to smell out enemies or track the scent of big animals.In addition to these hunting and working dogs,other breeds came to be used in sports,police work and as pets as well.In a way dogs have become man’s friends and working partners.
If you have a dog you love as a pet,you share some of your life with it.The dog lives in your home,keeps you company and goes on trips with you.Dogs rely on their excellent sense of smell to tell things apart.This sharp sense helps man and dogs themselves get over a lot of difficulties.
A detective once trained a dog---Sauer.In 1925 while he was thinking hard about how to catch a thief.Sauer worked alone and tracked the thief after covering a distance of 160 kilometres.Sauer did this by scent alone.In 1923 a couple lost their dog Bobbie while they were travelling.Six months later Bobbie turned up at the family house.He had covered a distance of some 3,200 kilometres.The dog had travelled back through the Rocky Mountains in the depths of winter.
Dogs are indeed man’s best friends.Yet sometimes even the friendliest dog can bring death with its bite!This is not because it has changed in character,but because it has been infected with a terrible disease---rabies(狂犬病).The disease is passed on by a bite from an infected dog at any stage.When an infected person shows symptoms,death is certain to follow shortly after.So,in order to prevent the disease,a person should go to a doctor at once if he has been bitten by a dog.Dogs remain man’s best friends,but we should also try our best to guard against the horrible disease that can be carried by these friends.
