One medical text from the fourth century suggested using the extract from sweet wormwood③ to treat a fever.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 stuck④.However，Tu Youyou would not acknowledge defeat⑤.She analysed the medical texts again，and by chance，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 out the extract，she found a substance that worked. eq \a\vs4\al([词海拾贝]) ①with the objective of 为了 ②malaria n. 疟疾 ③sweet wormwood青蒿 ④get stuck被困住 ⑤acknowledge defeat 承认失败 $$
