4．Norm Pethrick，a 36-year-old man in Australia's northern city Darwin，was praised on Thursday 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 Royal Darwin Hospital for a medical treatment．The doctors said she was suffering eight puncture wouds （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 the general manager of Royal Darwin Hospital （RDH），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 to four 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．

2．Food serves as a form of communication in two basic ways．Sharing bread or other foods is a common human tradition that can promote unity and trust．Food can also have a special meaning，and play an important role in a family or culture's celebrations or traditions．The foods we eat-and when and how we eat them-are often unique to a particular culture or may even differ between rural（郊区的） and urban（市区的） areas within one country．
Sharing bread，whether during a special occasion（时刻） or at the family dinner table，is a common symbol of togetherness．Many cultures also celebrate birthdays and marriages with cakes that are cut and shared among the guests．Early forms of cake were simply a kind of bread，so this tradition has its roots in the custom of sharing bread．
Food also plays an important role in many New Year celebrations．In the southern United States，pieces of corn bread stand for blocks of gold for prosperity（兴旺） in the New Year．In Greece，people share a special cake called vasilopita．A coin is put into the cake，which signifies（预示） success in the New Year for the person who receives it．
Many cultures have ceremonies to celebrate the birth of a child，and food can play a significant role．In China，when a baby is one month old，families name and welcome their child in a celebration that includes giving red-colored eggs to guests．In many cultures，round foods such as grapes，bread，and moon cakes are eaten at welcome celebrations to represent family unity．
Nutrition（营养） is necessary for life，so it is not surprising that food is such an important part of different cultures around the world．
