题型:单项选择题 A2型题 阅读理解。 One afternoon, when the lessons were over, John and Mike Ford did not go home. They stayed at school to help their teacher. Their teacher was starting a library in the school and the boys helped him to carry some books. They worked for one hour. Then the teacher said, "Thank you, boys. We will finish the work tomorrow. Now you must go home." When the boys got home, it was seven. It was dark outside but there was a light inside their home and the door was open. They could see a man inside. "Who can it be?" said John, "Mother and Father have gone shopping. They will come back after eight." When the man saw them, he looked frightened. Then he smiled and said, "Come in." You don't know me but I'm your father's friend. He has asked me to fetch (取, 拿) some money for him. The man did not see Mike. John went inside and began talking to the man but Mike did not. He quickly but quietly ran away to fetch a policeman. He soon found one and brought him back to their home. The man was still there, but when he saw the policeman, he tried to run away. The policeman stopped him and held his arm. At that moment, the boy's parents returned. Is this man your friend? the policeman asked Mr. Ford. No, said Mr. Ford. He is a thief.
