I still remember last winter, when I     1     (wake) up in the morning, it     2     (stop) snowing. Looking outside of the window, the shiny white snow on our lawn     3     (clean) by my father. I closed the book that I     4     (borrow) from our local library and went downstairs for breakfast. Then my little brother came to tell me that he     5     (finish) all his homework and he     6     (have) a very nice dream the night before. During the breakfast, one of my best friends came to visit my family. She     7     (go) to Australia last year. Before that she     8     (prepare) for the examination of University of Sydney for half a year. During her study, she     9     (learn) the culture and     10     (profession) knowledge in her field.
