单选题 One evening two young men were walking in the street together. They tried to find a chance to steal something. The clock struck twelve. Most of the people went to bed. Quietly they came to a house. There were no lights in the house and it seemed that everyone in the house had fallen asleep. Standing at the front gate, one said in English to the other in a low voice, "You wait here. I"ll go around to the back door and then get into the house-"-" Suddenly out of the house ran a dog, barking at them. The two men were very frightened and ran away as fast as they could. They dared not stop until they got to a lonely place. Gasping for breath, the man said, "It"s too bad. I hadn"t expected that the dog could understand English!"
