a married couple were very worried about
A married couple were very worried about their son.Although normal in every other way,he seemed to be dumb.Not once had he spoke and now he was six years of age.They had tried everything to get him to speak,but with no success.
　　The finest doctors in the country had examine him,but could find nothing wrong with his throat,and he seemed to be a very intelligent child.It was just that he never spoke.
　　“It’s possible,” one of the doctors said,“that there is something wrong with his mind,and he does not understand that he is capable(能够做到的) of speech.”
　　“But he can read and write,” the boy’s father said.“We’ve written him notes,telling him that he can speak,begging him to speak.”
　　“It’s certainly very strange,” the doctor said.“Perhaps he’ll grow out of silence one day.”
　　The years passed.The boy left primary school and went to secondary school.He left secondary school and went to university.But he didn’t speak a single word.
　　Then,one day,during a summer vacation,he was sitting at the dining table having a meal with his parents.
　　Without any warning,he looked up from his meal and said,“Pass the salt,please.”
　　His parent were overjoyed.
　　“You spoke!You spoke!” they cried.“Why have you waited so long to speak?”
　　The young man looked at them,surprised by their attitude(态度).
　　“I didn’t have anything to say,” he said.“Until now everything’s been perfect.But you obviously forgot to put salt in these potatoes.”
