Para 3
Tu's education was soon to prove very useful . In the 1960s, many people were dying of malaria , and in 1969 Tu became head of a team that intended to find a cure for the disease . She collected over 2,000 traditional Chinese medical recipes for malaria treatment and made hundreds of extracts from different herbs .
屠呦呦接受的教育很快被证明非常有用。20世纪60年代，许多人死于疟疾，于是1969年屠呦呦担任了一个旨在找到疟疾疗法的小组的组长。她收集了2000多种治疗疟疾的中药配方，并从不同的草药中获取了数百种提取物。

When they failed to produce any promising results , Tu referred to the ancient books of traditional Chinese medicine again . Inspired by an over 1,600-year- old text about preparing qinghao extract with cold water , Tu redesigned the experiments and tried extracting the herb at a low temperature in order not to damage its effective part . On 4 October 1971, after 190 failures , she succeeded in making qinghao extract that could treat malaria in mice .
当这些未能取得任何有希望的效果时，屠呦呦就再次查阅中医典籍。在一本1600多年前的典籍中，关于用冷水制备青蒿素提取物的记载给了屠呦呦启发，她重新设计了实验，并尝试在低温下对这种草药进行提取，以不损害其有效成分。1971年10月4日，在历经190次失败后，她成功制备出可以治疗老鼠疟疾的青蒿提取物。

However , it was hard to produce enough qinghao extract for large trials because research resources were limited . Tu and her team managed to find solutions to the problem . When there was no research equipment , they had to extract herbs using household water containers . They worked day and night and their health began to suffer because of the poor conditions , but they never gave up .
Para 4
然而，由于研究资源有限，很难制造出足够的青蒿提取物用于大规模试验。屠呦呦团队成功找到了解决这个问题的方法。当时没有研究设备，他们只好用家用储水的容器来提取草药。他们夜以继日地工作，由于条件恶劣，他们的健康开始受损，但却从未放弃。

2.Why did they lack qinghao extract for large trials
A. Because research resources and good equipment were in short supply.
B. Because Tu and her team lacked experience.
C. Because there was no good laboratory for experimenting.
D. Because they had no support from the government and their families.

Para 5
Even with large amounts of qinghao extract produced , however , they still faced another problem . The trials on patients were likely to be postponed because they did not have sufficient safety data . To speed up the process and ensure its safety , Tu and her team volunteered to test qinghao extract on themselves first.
然而，及时制造出了大量的青蒿提取物，他们仍然面临着另外一个问题。由于没有足够的安全数据，对患者的试验可能会被推迟。为了加快进度并保证其安全性，屠呦呦和她的团队自愿在自己身上试验青蒿提取物。

Para 6
The efforts of Tu and her team finally paid off . In November 1972, through trial and error , they successfully discovered qinghaosu-- the most effective part of the qinghao extract . As a key part of many malaria medicines , qinghaosu has since benefited about 200 million malaria patients .
屠呦呦团队的努力最终得到了回报。1972年11月，经过反复试验，他们成功发现了青蒿素——青蒿提取物中最有效的成分。作为许多抗疟疾药物中的关键成分，青蒿素迄今已经造福了近2亿疟疾患者。

More than 40 years after its discovery , Tu was eventually awarded a Nobel Prize for her work. In her Nobel Lecture , she encouraged scientists to further explore the treasure house of traditional Chinese medicine and raise it to a higher level . Perhaps the next generation of scientists , drawing on the wisdom of traditional Chinese medicine , will indeed discover more medicines beneficial to global health care .
在发现青蒿素40多年后，屠呦呦终于因此获得诺贝尔奖。在她的获奖演讲上，屠呦呦鼓励科学家们进一步探索中医这座宝库，并让其更上一层楼。也许，新一代的科学家汲取中医的智慧，确实能发现更多有益于全世界医疗的药物。
