He found on arriving at the port that all his relatives were having a large party.He was in such a happy mood and in the joy of the moment, he did not even bother changing his grey flannel（法兰绒）suit which had become a little worn during the trip home.When he entered the brilliantly lit room, his relatives and friends gave him a rather cold welcome because they had noticed his modest suit and immediately imagined that he had come back a poor man.A young man who happened to be accompanying him was quite irritated at this and said to Willy, “What a wonderful reception you have received from these people. They have not even the intention of shaking your hand after all these years that you have been away from home.”“Just wait and see!” whispered Willy, “They will soon change their looks!” Saying this he slipped a precious ring on his finger. All of a sudden the faces of all those present lit up and immediately Willy was surrounded by so many people that he didn’t know what to do. A man shook his hand, a cousin threw his arms around him, and he had so many invitations from the people present that he thought he would be unable to make any other appointments for several years.“Has this beautiful, precious ring of yours the power of magic people?” asked the young man.“Oh, no!” replied Willy, “They see in this glittering diamond ring something that makes them think I am rich, and, unfortunately, they place wealth above everything else.”"What blind people!" exclaimed the young man. “It is not the ring that has drawn them to you but their desire for riches. Is it possible to appreciate more a piece of yellow metal surrounded by little stones than the goodness of my Lord? And indeed how foolish are people who place their trust in riches rather than in virtues（美德）!”小题1: In what way did Willy go to attend the party held by his relatives and friends?A．In such a modest mood.B．In travel-soiled clothes.C．Wearing a precious jewel.D．Without being accompanied.小题2: The word “irritated” in the fourth paragraph is closest in meaning to “______”.A．excitedB．pleasedC．angry D．envious小题3: According to the young man, people should ______.
