Montreal French-language station CKMF--FM said last Wednesday that staffers (工作人员) Marcantoine Audet and Sebastien Trudel had a 10-minute telephone chat with Microsoft Corp boss Gates on April 1. The broadcast was aired on their nightly show last Tuesday and repeated last Wednesday. “We were happy. We had been calling Microsoft persistently (坚持不懈地) for four weeks,” Trudel said. Trudel said he and his colleague had already fooled Canadian pop singer Celine Dion and Formula One (一级方程赛车) driver Jacques Villeneuve on their show. “This time, we wanted to give ourselves a challenge with somebody more difficult to reach,” Ttudel said. He said he was surprised that Gates’s assistants did not check to see if it was really the prime minister’s office on the line. Trudel said they imitated (模仿) Chretien’s heavily accented English, talking about the economy, asking about Microsoft’s Windows operating system and inviting the multibillionaire to visit a well-known Montreal strip joint (运动服合资企业). The radio host said that Gates was not amused by the fake interview.“He did not seem angry but he did not find it so funny,” the comic said. 【小题1】Bill Gates was fooled mainly because ______.A．his assistants were not careful enoughB．the Canadian Prime Minister helped the two comicsC．the two comics imitated the Canadian Prime Minister so wellD．it was April Fool’s Day【小题2】We can conclude from the passage that the two comics ______.A．liked to fool famous people on their show　B．thought that Gates was not a great challenge to themC．had a good knowledge of Bill Gates and his Windows operating systemD．were not quite satisfied with their tricks【小题3】Which of the following would be the best title of the passage?A．Gates ‘April Fooled’B．Two Comics and Their TricksC．Two comics and Their ShowD．A Fake Interview
