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.

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! Revision In her Nobel Lecture, Tu Youyou (1) __________ the strengths of both traditional Chinese medicine and Western medicine, and pointed out that there is great potential for future advances if scientists make good use of these strengths. Their efforts to conduct research in both fields may finally (2) ________.
