Our three-year-old daughter Becky wanted a dog．But we were too busy to buy one．One day，Becky ran in，shouting，"Mom!Come to see my dog!"Her face was red with excitement．
I followed her to the bush and found a wolf!He was hurt．Seeing me，he stood up suddenly!I could see his teeth!God!My mouth felt dry．"Don't be afraid．That's Mom．She loves you，too，"Becky said．Then he became friendly．It was unbelievable!
I rushed to find my husband and told him about the wolf．We should have killed the wolf，but Becky loved him．Besides，he was gentle to Becky．So we called the vet finally．
Becky named the wolf Ralph and she carried food to him every day．Later，Ralph got well．They played together in the daytime．At night，Ralph would return to the mountains．Sometimes he disappeared but came back several days later．
On Becky's first day of school，we could see Ralph's sadness．After the school bus left，Ralph lay by the side of the road and waited．When Becky returned，he got happy again．This continued throughout Becky's school years．
Twelve years passed．One day we heard that a wolf was killed．The other wolf was hurt and ran away．We were worried about Ralph．That night，Ralph returned with a wound（伤口）．Becky held his head kindly and comforted him．We hope he could come through．However，he died．
Becky cried．I noticed something strange in the bush---two little yellow eyes!Ralph's child!Before he died，Ralph brought his child to us!He knew he would be safe here，as he had been．Ralph，Ralph…I was moved．

4．The letters'UFO'mean'Unidentified Flying Object'．To many people this means flying plates!However，not all UFOs have looked like plates．Many have been long and thin．Some have been balls of light．
Many people think that UFOs come from deep in space．This may be not true．Unless a UFO can be identified，we cannot say where it comes from．
Although we have not been able to get a UFO and examine it，thousands of people believe that they have seen such things．
A famous example was in Mississippi in 1973．Two men，Charles E．Hickson，45，and Calvin R．Parker，18，said that they were taken on board a UFO．
They were fishing when a green light appeared above them．Inside the light there was some kind of object from which three strange creatures came out．These creatures had claws instead of hands，pointed ears，a small pointed nose and a hole beneath it for a mouth．They had legs but did not walk，they seemed to swim in the air．
Hickson and Parker said that they tried to move but could not．The creatures lifted them up and carried them into their spaceship．Here the creatures used strange objects to study every part of their bodies．
The creatures later returned the two men to where they had been fishing and then left as suddenly as they had arrived．
Many people believed that Hickson and Parker were telling the truth because on the same day in different parts of the country，two other people，many kilometers away from one another，saw similar creatures．
One of them was a policeman．He took photographs of the creature he saw and drove after it in his police car．Unluckily，he could not catch it．
In fact，no one who has seen a visitor from a UFO has ever been able to catch and keep one for study．Or if they have，they are not telling anyone about it!
