In 2019, Tu Youyou was selected by the BBC as one of the most influential     1     (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     2     (wise) and new methods to achieve her goals and the fact that her work     3     (bridge) the Eastern and Western worlds,     4     (save) millions of lives.

In 1969, Tu Youyou     5     (choose) to establish a team to find a cure for malaria (疟疾). This was not     6     easy task. The reason why this was difficult was that the team had     7     (limit) resources. They did not have enough staff, and the laboratory     8     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,     9     they had to know if it was safe for humans. Tu Youyou     10     (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 a success. The medicine they discovered, artemisinin (青蒿素), has now become the world’s most effective drug for malaria.

TU YOUYOU AWARDED NOBEL PRIZE

6 October 2015

This year’s Nobel Prize for Physiology or Medicine has been awarded to Tu Youyou (co-winner), the research of     1    led to the discovery of artemisinin, a crucial new treatment for malaria. Artemisinin has saved hundreds of thousands of lives, and has led to     2    (improve) 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     3    (think) to save 100, 000 lives a year in Africa alone.
