【简答题】
A 37-year-old man in Australia’s Northern city Darwin ,Norm Pethrick, was praised for jumping onto a crocodile’s back to save his wife Wendy at Litchfield National Park, a popular tourist spot southwest of Darwin, a local newspaper reported. Ms Pethrick was standing on a river bank Wednesday afternoon when the saltwater crocodile lunged (扑), locking its jaws on both her legs as it tried to drag her underwater. Norm Pethrick, who with his wife had been collecting water, immediately went to help her. He jumped onto the back, poked (戳) the eyes of the crocodile and finally got his wife free. Ms Pethrick was later taken to Hospital for a medical treatment. The doctors said she was suffering eight puncture wounds (伤口) in her right leg, a puncture wound in her left leg and a serious cut to one of her fingers. “This could have been a fatal and tragic situation,” said Dr Len Notaras, according to a local report. He said Ms Pethrick was saved by her husband’s “quick and diligent actions”. Dr Notaras also said she would remain in hospital for three more days and have an operation to clean the wounds, which are easy to get infected because of bacteria (细菌) on the teeth of the crocodile. 小题1: This passage is most likely to be found in _____.
