19、health for millions of people.Over 200 million people around the world get malaria each year,and about 600,000 die from it.Artemisinin has become a vital part of the treatment for malaria,and is thought to save 100,000 lives a year in Africa alone.Para 1Tu Youyou,a committed and patient scientist,wa

21、atment 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 project in Beijing,and decided to review ancient Chinese medical texts to find traditional bota

25、perature to draw out 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 testing the medicine on themselves to make sure that it was safe.Later,the medicine was tested on malaria patients,m

26、ost of whom recovered.This medicine,which was called artemisinin,soon became a standard treatment for malaria.Para 3According 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.”Para 4
