    Mr and Mrs Brown were going abroad for their holiday. They had a dog called Blackie which they were

very fond of, but they could not take him abroad with them, so they looked for a good place to leave him in

while they were away, and at last found a place which looked after dogs very well while their owners were

away. They took Blackie there just before they left for their holiday, and sadly said goodbye to him.

    At the end of their holiday, they got back to England very late at night, and as they thought that the place

where Blackie was staying might be closed at that hour, they decided to wait until the next morning before

going to get him back.

    So the next morning Mr Brown got into his car and drove off happily to collect Blackie.

    When he reached home with the dog,he said to his wife. "Do you know, dear, I don't think Blackie can

have enjoyed his stay at that place very much. He barked all the way home in the car as if he wanted to tell

me something."

    Mrs Brown looked at the dog carefully and then answered, "You are quite right, dear. He was certainly

trying to tell you something. But he wasn't trying to tell you that he hadn't enjoyed his stay at that place, he

was only complaining (抱怨) that you were bringing the wrong dog home. This isn't Blackie!
