In 2019, Tu Youyou was selected by the BBC as one of the most influential (figure) 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 (wise) and new methods to achieve her goals and the fact that her work (bridge) the Eastern and Western worlds, (save) millions of lives.
In 1969, Tu (choose) to establish a team to find a cure for malaria. This was not an easy task. The reason why this was difficult was that the team had (limit) resources. They did not have enough staff, and the laboratory 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, they had to know if it was safe for humans. Tu (brave) 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 success. The medicine they discovered, artemisinin, has now become the world's most effective drug for fighting malaria. Many have heard of shark's fin soup.
