1、Tu Youyou， the first Chinese woman to win a Nobel Prize in science， has made us all proud. Tu， born in 1930， discovered artemisinin (青蒿素)， a drug that has reduced the death rates for patients suffering from malaria (疟疾). “Artemisinin is a gift for the world people from the traditional Chinese medici
2、ne”. It is of great importance for curing malaria and other infectious diseases and for protecting the health of the world people.Tus winning the prize shows that China has made rapid progress in scientific and technological field and marks a great contribution of traditional Chinese medicine to the
3、 cause of human health.Tu was born in Ningbo， Zhejiang province， China on 30 December， 1930. Tu studied at Beijing Medical University School of Pharmacy， and graduated in 1955. Later Tu was trained for two and a half years in traditional Chinese medicine. Tu worked at the Academy of Chinese Medicine
4、 in Beijing after graduation. She was promoted to a researcher in 1980 only after the Chinese economic reform. In 2011， Tu became the first scientist in China to win Americas Lasker Award (拉斯克奖) for her achievements. Currently she is the Chief Scientist in the Academy.Section_Warming Up & Reading Pr

19、河水被从伦敦排放的脏水污染了。他马上叫宽街上惊慌失措的百姓拆掉水泵的把手，这样，水泵就用不成了。不久，疫情就得到缓解。他证明了霍乱是由病菌而不是由气体传播的。In another part of London, he found supporting evidence from two other deaths that were linked to the Broad Street outbreak.
