A

One morning I met a man in my shop. He wanted to buy some new clothes. First I gave him a pair of trousers. He put them on to try, then        and gave them back to me and said, “No, give me a coat instead of them.”

I gave him a coat and told him, “This one is worth as much as the trousers.” To my surprise he took the coat without saying a word and walked out of the shop with it. I ran quickly after him and said, “You haven’t paid for that coat!” 

“But I gave you the trousers for the coat,” he said. “They are worth（相当于…的价值） the same as the coat, aren’t they?”

“Yes,” I said. “You didn’t pay for the trousers, either!” “Of course I didn’t!” answered the man, “I didn’t take them. I am not foolish! Nobody gives things back and then pays for them.”
