The woman was Tu Youyou, the first Chinese female scientist⑥ to be awarded a Nobel Prize for⑦ her work. A scientist who was on the Nobel Prize Committee⑧ called Hans Forssberg  explained that “the discovery of artemisinin has led to⑨ the development of new drugs which have saved the lives of⑩millions”. When thanking the Committee for⑪ the honour， Tu Youyou said, “This is not only an honour for myself, but also⑫ recognition and encouragement for all scientists in China.” Tu Youyou was born in⑬ Zhejiang Province, China, on 30 December, 1930.She studied medicine at Peking University Health Science Centre.After graduation, she became a member of⑭ China Academy of Chinese Medical Sciences.Later she studied Chinese medicine⑮ for two and a half years⑯ with experts in the field from whom she gained a deep knowledge about traditional practices . In 1969, Tu Youyou was chosen to establish a team  to find a cure for⑱ malaria— a disease that killed millions of ⑲ people every year. Across the world, scientists had been trying to⑳find a cure.They tested more than240，000 chemicals with no success.However, Tu Youyou had an ideathat Chinese herbs might hold the secret .She studied ancient Chinese medical literature and visited experts in traditional Chinese medicine.She researched hundreds of traditional recipes connected to anti-malarial cures. Then Tu Youyou and her team began using modern research methodsto study these Chinese herbs one by one. This was not an easy task.The reason why this was difficult was that the team had limited resources. They did not have enough staff, and the laboratory in which they worked had poor air quality. However, after hundreds of failed experiments, they eventually came acrossa promising chemical.It worked well in experiments on animals, but they had to know if it was safe for humans, Tu Youyou bravely volunteered to be the first human subject when they were ready to start testing and the rest ofher team followed her.The test was a success.The medicine they discovered, artemisinin, has now become the world's most effective drugfor fighting malaria. Even thoughTu Youyou is not interested in fame, she has become a scientist whose work is internationally renowned. In 2019, she was selected by the BBC as one of the most influential figures of science in the 20th Centuryalong with Albert Einstein and Alan Mathison Turing.Tu Youyou was noted forher bravery in being a scientist during a difficult time for science in China, her ability to use old wisdom and new methods to achieve her goals and the fact that her work bridged the Eastern and Western worlds, saving millions of lives. Today Tu Youyou continues to conduct researchdespite her age.According toTu Youyou, “From our research experience in discovering artemisinin, we learnt the wisdom behind both Chinese andWestern medicine.There is great potential for future advances if these two kinds of wisdom can be fully integrated，” she said. which引导的非限制性定语从句。 不定式作定语。当名词前面有序数词修饰的时候，往往用不定式作它的定语。 who引导的定语从句修饰先行词A scientist。 非谓语动词作定语修饰A scientist，call与scientist之间是被动关系。 which引导的定语从句，修饰先行词drugs。 when引导的时间状语从句。 “介词＋关系词”形式的定语从句，修饰先行词experts。 that引导的定语从句，修饰先行词a disease。同时，关系词在从句中作主语。 同位语从句。that Chinese herbs might hold the secret是对an idea内容的解释说明。 非谓语动词作定语，recipes与connect之间是被动关系。 不定式短语作目的状语。 why引导的定语从句，修饰先行词reason。 表语从句。 which引导的定语从句，修饰先行词the laboratory。 if引导的宾语从句表“是否”。 when引导的时间状语从句。 定语从句，修饰先行词The medicine。 artemisinin与The medicine是同位关系。 even though引导的让步状语从句。 whose引导的定语从句，修饰先行词a scientist。a scientist与work之间是所有关系。 that her work bridged the Eastern and Western worlds, saving millions of lives是同位语从句，是对the fact内容的解释说明。 if引导的条件状语从句。 二、语篇研读 1．Discussing—Look at the following pictures and discuss what you know about them. 2．Predicting—Look at the pictures on Page 52 and predict what the text is probably about.
