5、或医学奖授予了屠呦呦(共同获奖者)，她的研究促使了青蒿素的发现。这是一种至关重要的治疗疟疾的新疗法。青蒿素挽救了数十万人的生命，并改善了数百万人的健康状况。全世界每年有超过2亿人罹患疟疾，约60万人死于疟疾。青蒿素已成为治疗疟疾的重要组成部分，据认为仅在非洲一年就能挽救10万人的生命。Reading Tu Youyou,a committed and patient scientist,was born in Ningbo,China.On 30 December 1930，and graduated from Peking University Medical School in 1955.

10、69年，她成为北京项目的负责人，并决定复阅中国古代医药文献，寻找这种疾病的传统植物疗法。她的团队查阅了2000多本古老的医药文献，并对280 000种植物的药用价值进行了评估。在他们的研究中，他们发现并测试了380种不同的中国古代疗法，这些方法为抗击疟疾带来了希望。Reading One medical text from the fourth century suggested using the extract from sweet wormwood to treat a fever.Tus team tested a collection of dried wormwood leaves

11、 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 stuck.However,Tu Youyou would not acknowledge defeat.She analysed the medical texts again,and by chance,she found one sentence suggestin

16、论，煮青蒿显然破理青蒿。她得出结论，煮青蒿显然破坏了它的药用价值。她用较低的温度坏了它的药用价值。她用较低的温度提取提取物，发现了一种有效的物质。提取提取物，发现了一种有效的物质。在失败了在失败了190多次之后，这个团队终多次之后，这个团队终于在于在1971年成功了。屠呦呦和她的年成功了。屠呦呦和她的团队成员甚至坚持在自己身上测试药团队成员甚至坚持在自己身上测试药物，以确保它是安全的。后来，这种物，以确保它是安全的。后来，这种药物在疟疾患者身上进行了测试，大药物在疟疾患者身上进行了测试，大部分受试患者都康复了。这种被称为部分受试患者都康复了。这种被称为青蒿素的药物很快成为治疗疟疾的标青蒿素的药

17、物很快成为治疗疟疾的标准药物。准药物。According to Tu Youyou,the discovery of artemisinin was a team effort.Upon hearing that she had been awarded the Nobel Prize,she said,“The honour is not just mine.There is a team behind me,and all the people of my country.This success proves the great value of traditional Chinese medicine.It is indeed an honour for Chinas scientific research and Chinese medicine to be spread around the world.”Upon hearingUpon hearing一一就就屠呦呦说，青蒿素的发现是一个团队努力的结果。当听到自己被授予诺贝尔奖时，她说：“这个荣誉不仅仅属于我。在我身后有一个团队，还有我的国家的全体人民。这一成功证明了中医的巨大价值。中国的科学研究和中医药走向世界，确实是一种荣誉。”
