听力原文: An Australian engineer is reported to be held hostage in Iraq. His American wife identified 63-year-old Douglas Wood from a video released Sunday in which he is seen pleading for coalition forces to leave Iraq. She said that he's been working in Iraq for about 18 months. The couple lives in California. Australia's prime minister says there will be no negotiations with hostage takers. The kidnapping came hours after US and Iraqi forces detained several men thought to be linked to the killing of aid worker Margaret Hassen, a British hostage who was seized last year. What happened to the Australian engineer?
