Tu Youyou is awarded the 2015 Nobel Prize.
What do you know about the Nobel Prize
A Nobel Prize is one of a set of prizes that are awarded each year to people who have done important work in science, literature, or economics, or for world peace.
What important scientific discoveries
in history have you heard about
Alexander Fleming discovered penicillin in 1928.
Behind every scientific discovery lies a lot of hard work.
The news report below describes the Chinese scientist Tu Youyou and her discovery of a life-saving medicine.
Now, let's read the news report to learn more.
Task 1

Tu Youyou acquired a broad knowledge of both traditional Chinese medicine and Western medicine.
Tu Youyou and her team solved a lot of problems before they successfully discovered qinghaosu.
Tu Youyou and her team's efforts finally paid off.
Task 3
Read the news report again carefully and fill in the table below.
P46 A2
Problems Solutions
The extracts failed to produce any promising results.
Tu and her team could not produce enough qinghao extract because research resources were limited.
Tu and her team did not have sufficient safety data to start trials on patients.
Tu Youyou referred to the ancient books of traditional Chinese medicine again, redesigned the experiments and tried extracting the qinghao herb at a low temperature in order not to damage its effective part.
Tu Youyou and her team managed to find solutions to the problem, e.g. using household water containers instead of research equipment.
Tu Youyou and her team volunteered to test the qinghao extract on themselves.
Thank you!
