Last Saturday Mr Ma and his wife went out to take a walk. They came back at
eight in the evening.When they walked to the front door, Mr Ma said,"Listen, I
can hear someone in the living-room.""Yes, you are right," said Mrs Ma. "There
are two men there. They are talking." Then they shouted, "Who's there?"But no
one answered.Mr Ma opened the door quickly and truned on the light.There was
nobody!Then Mr Ma laughed. The TVwas still on. "Oh, I forgot to turn it
off."

　　上星期六马先生和妻子出去散步，晚上8点才回来。当他们走到门前时，马先生说：“你听，我能听到客厅里有人!”“是的，你说得对，”马太太说，“那里有两个人，他们在说话。”
然后他们喊到：“谁在那里?”可是没有人回答。马先生迅速地打开门，并把灯打开。没有人!后来马先生笑了，原来电视机还开着呢!“噢，我忘了关电视了!”
