A dog entered a butcher's shop with a note in his mouth. The note read, "$10 of lamb chops （羊排）, please. "

    The butcher was very  （surprise）. He took the money, put a bag of chops in the  （dog） mouth, and then he closed the shop  （quick）. He followed the dog and watched him wait for a green light. Then the dog crossed the road to a bus stop. He checked the timetable and sat on the bench. When a bus arrived，the dog checked the number and got  it.

    As the bus traveled out into the countryside, the dog enjoyed the scenery. After  while, he stood on his back paws  （push） the "stop" button. Then the butcher followed  （he） off.

    The dog ran up to a house and dropped his bag on the ground. He went back down the path, took a big run, and  （throw） himself against the door. No answer. He repeated the action a few times. Then a big man opened the door  started complaining about the dog and beating him.

    Seeing this, the butcher ran up and shouted at the man, "What are you doing? This dog is a genius!" The man replied, "Genius? No way! He has forgotten his key for the  （four） time this month!"
