It was a beautiful spring morning. There were no clouds in the sky, and the sun was warm but not hot. Mr Black saw an old man at the bus stop with a big, strong, black umbrella (伞) in his hand. Mr Black said to him, “Do you think we are going to have rain today?” “No,” said the old man, “I don't think so.” “Then are you carrying the umbrella because the sun is too hot?” “No, the sun is not very hot in spring.”
Mr Black looked at the big umbrella again, and the man said, “I am an old man, and my legs are not very strong. I must have a walking-stick (手杖). But people will say, ‘Look! That man is so old.', and I don't like that. When I carry an umbrella in fine weather, people only say, ‘Look at that stupid (愚蠢的) man.”
