It was a pity that she didn't live to celebrate (庆祝) her 100th birthday, 2 she had a good, long life. She had already been a professional 3 before many women had jobs. She taught in Africa for many years. Then she moved to Malaysia and taught English there for a few years. At that time, people didn't tralvel 4 a plane, so she had to travel there by ship. It took her three months 5 from England to Malaysia in those days. In 1947, she traveled by plane for the first time. This made traveling 6 easier and quicker. She continued to teach around the world until she was 75 years old. Jenny really loved teaching and she was also good at telling stories. I always loved to hear her 7 her stories.
