单元话题导入 [品读话题短文] Tu Youyou，a committed and patient scientist，was born in Ningbo，China，on 30 December 1930，and graduated from① Peking University Medical School in 1955.After she graduated，she worked at the China Academy of Traditional Chinese Medicine in Beijing. In 1967，the Chinese government formed a team② of scientists with the objective of③ discovering a new treatment for malaria，and Tu Youyou was among the first researchers chosen. In the beginning，Tu Youyou went to Hainan，where malaria was more common，to study malaria patients. In 1969，she became the head of the project④ in Beijing，and decided to review ancient Chinese medical texts to find traditional botanical treatments for the disease. Her team examined over 2，000 old medical texts，and evaluated 280，000 plants for their medical properties. From their research，they discovered and tested 380 distinct ancient Chinese medical treatments that showed promise in the fight against⑤ malaria. One medical text from the fourth century suggested using the extract from sweet wormwood to treat a fever⑥.Tu's team tested a collection of dried wormwood leaves but found no effect. They then tried boiling fresh wormwood，and using the liquid obtained from this to treat malaria，but this did not work either. Their project got stuck⑦.However，Tu Youyou would not acknowledge defeat. She analysed the medical texts again，and by chance⑧，she found one sentence suggesting a different way to treat the wormwood. She concluded that boiling the sweet wormwood apparently destroyed its medical properties. Using a lower temperature to draw out⑨ the extract，she found a substance that worked. After failing more than 190 times，the team finally succeeded in 1971.Tu Youyou and her team members even insisted on testing⑩ the medicine on themselves to make sure that it was safe. Later，the medicine was tested on malaria patients，most of whom recovered. This medicine，which was called artemisinin，soon became a standard treatment for malaria.
