9、In the eighteenth century young ladies in Italy knew history and geography little. Once the French officer in Rome was giving a ball to which many important people were invited. The Italian Minister（大臣） came very late. A young lady, who knew him, saw him enter the ball-room and asked why he was so late. "Oh, nothing important," answered the Minister. " Our head forgot to take his letters with him and went back to his hotel to bring them. If he had left them in Brazil we should have had to wait at least six months for them." "Is Brazil so far from Rome?" asked the lady, who knew very little geography. "It is in the New World," said the Minister. "In the New World?" repeated the lady in great surprise. "Yes, in the New World, which was discovered by Christopher Columbus." When the young lady heard this, she rushed into the middle of the ball-room and shouted as loud as she could: "Ladies and gentlemen, have you heard the latest news? A new world has just been discovered by a certain Christopher Columbus."统考英语阅读理解
