A man bought a donkey at the market one day and took him home. Now the man owned several donkeys already and he knew each one’s character very well. One of the donkeys was very strong and brave. Another always wanted to make people happy by working quickly but soon got tired. One donkey was very lazy. He hated going to work in the morning and he did as little as he       possibly could all day long. When the other animals were being loaded up(装载), he always tried to be the last so that he would get the lightest load.
The man led the new donkey into the yard. For a moment the new donkey stood sniffing(闻，嗅) at his new friends. Then, without hesitation, he came up to the lazy donkey and began eating comfortably at his side.
Though it was late in the day, the man immediately led the new donkey out of the yard, straight back to the market.
“You can’t have given him a fair trial yet,” said the seller, “It is only ten minutes since you bought him.”
“I don’t need to try him any more,” replied the man, “I know just what he is like from the friend he chose for himself. Take him away and give me my money back. I can do without donkeys like him.”
