III: Read and answer the questions. CHRISTMAS IN AUSTRALIA In Australia, the day before Christmas is hot. Christmas is during the summer months and it is the beginning of a nice holiday time for pupils. Families which have relatives in Europe, dream of having a traditional white Christmas once in their lives. Children would like to build a snowman or go skiing, as they know it from the pictures, Christmas stories and Christmas cards. In Australia, Christmas presents are distributed in the morning 25th of December. It is called Christmas morning. The electric candles burn on the Christmas tree, the family sings Christmas carols and unwraps their presents. After that, children go outside or down to the beach because it is usually very hot --- about 35 degrees C. At the same time, the rest of the family prepares Christmas lunch. Some families have a big meal outside in the garden, others have it inside the house because it is cooler there. 1.
