In 1955，Wu voluntarily went to work in Shanshan County，Turpan Basin in northwest China's Xinjiang Uygur Autonomous Region where working conditions were hard.In 1958，Wu began to promote the modern technology of cultivating(种植) melons among farmers.However，the local farmers who were used to folk cultivation methods didn't want to change.With the help of a famous local melon expert，Wu opened up three acres of wasteland to plant melons according to scientific knowledge.When autumn arrived，local farmers found the melons Wu planted in a scientific way were particularly delicious.From then on，the farmers began to adopt Wu's scientific growing methods. Wu's efforts to grow quality melons began paying off in 1973 when she set up an off­season breeding(培育) base in Hainan.She wanted to develop Hainan as a pilot area to improve the speed and efficiency of breeding so that the south area of China could also grow melons，and realize the dream of three­matured or even four­matured melons.After numerous difficulties，finally in the 1980s，the melon variety selected by Wu succeeded.Wu said，“In Xinjiang，there are thousands of science and technology workers like me.They have worked hard for decades on the frontline of agriculture.I'm just one of the ordinary ones.” Now dealing with Alzheimer's disease，Wu is often unable to recognize her former colleagues or even her family members who live by her side.But having worked day and night to cultivate new varieties since the 1950s，she can still remember her melon work. 1．What does Wu's colleague think of her?
