听力原文： Linda left school when she was seventeen years old and went to a college for a year to learn to type. She passed her examinations quite well and then went to look for work. She was still living with her parents. A lot of people were looking for typists at that time, so it was not difficult to find interesting work. Linda went to several offices, and then chose one of them. It was near her parents' house. She thought, 'I'll walk there every morning. I won't need to go by bus.' She went to the office again and said to the manager, 'I want to work here, but what will you pay me?' 'We'll pay you ＄35 now,' the manager answered, 'and ＄40 after three months.' Linda thought for a few seconds before she answered. Then she said, 'All right, then I'll start in three months' time.' What did Linda do after graduating from college?
