One Day, Mr Black sees a sweater in a shop window. He decides to buy it because it is very cheap. When she gets home, he put the sweater on. It fits ( 适合) him very well and he is very happy. In the afternoon, he goes out to work in his garden. It soon begins to rain. Mr Black has run into the house. He runs quickly, but he still gets wet. Then his sweater starts to shrink! It gets smaller and smaller. Soon it is so tight that he couldn’t breath ( 呼吸) . In the end, with great difficulty and with the help of his wife, he takes off the sweater.
