(课件网) Tu Youyou is awarded the Nobel Prize for Physiology or Medicine because she has discovered artemisinin，a crucial drug formalaria.In fact，artemisinin has become a vital part of the treatment for malaria. After graduating from university，Tu Youyou worked at the ChinaAcademy of Traditional Chinese Medicine. She committed herself to the objective of discovering a new treatment for malaria. She and her scientific research team tried to find traditional botanical treatments for the disease. They evaluated 280，000 plants and tested 380 distinct ancient Chinese medical treatments. 屠呦呦获得了诺贝尔生理学或医学奖，因为她发现了治疗疟疾的关键药物青蒿素。事实上，青蒿素已经成为疟疾治疗的重要组成部分。大学毕业后，屠呦呦在中国中医研究院工作。她致力于发现疟疾新疗法的目标。她和她的科研团队试图找到治疗这种疾病的传统植物疗法。他们评估了28万种植物，并测试了380种不同的古代中医疗法。 Tu’s team tried boiling fresh wormwood，and using the liquid obtained from this to treat malaria，but this did not work.Tu Youyou wouldn’t acknowledge defeat. She insisted on analysing the medical texts again and drew a conclusion that boiling the sweet wormwood apparently destroyed its medical properties. By using a lower temperature to draw out theextract，she discovered the effective substance.Artemisinin，like penicillin，has stood up to clinical tests，just as other products or devices can stand wear and tear. 屠的研究小组尝试将新鲜的青蒿煮沸，然后用从中提取的液体治疗疟疾，但没有成功。屠呦呦不承认失败。她坚持要再次分析医学文献，并得出结论，煮沸这种青蒿显然破坏了它的医学特性。她用较低的温度获取提取物，发现了这种有效的物质。青蒿素和青霉素一样，经得起临床检验，就像其他产品或设备经得起磨损一样。 crucial adj. 至关重要的；关键性的 1.同义词=vital=essential 2.be crucial /vital to /for ...对......至关重要 e.g:Clean water is crucial for human survival. 翻译：均衡的饮食对身体健康至关重要。 e.g:Oxygen is crucial/vital/essential for life.
