Question

Ireland，Japan，China scientists share the 2015 Nobel Prize for medicine．William Campbell，Satoshi Omura and Tu Youyou jointly won the prize for their work against diseases，the award-giving body said on Monday．

Tu Youyou, a scientist at the China Academy of Chinese Medical Sciences, has no postgraduate degree. She has never studied or done research abroad. She is neither a member of the Chi­nese Academy of Sciences nor the Chinese Academy of Engineering. However, the 81-year-old phar­macologist has become the first scientist on the Chinese mainland to win a Lasker Award, the medical prize of the Albert and Mary Lasker Foundation.

The Lasker Awards have existed since 1945. Tu was presented the 2011 Lasker Clinical Medical Research Award on September 23. She discovered a drug called artemisinin . The drug is now widely used against malaria .

Tu and her colleagues joined a government project to find a new malaria drug in the late 1960s during the "cultural revolution" (1966-76).  They made 380 herbal extracts from 200 potential recipes. The recipes came from traditional Chinese medical books. The team then tested them on malaria-infected mice.  Finally Tu became interested in an extract of the plant qinghao, or sweet wormwood .

According to an ancient Chinese medicine book, qinghao was once used to treat malaria. However, the extract they made in the lab didn't work well. Maybe, thought Tu, the effective ingredient in qinghao was destroyed by high temperatures. Therefore, Tu tried to make the extract with an ether which has a much lower boiling point than water.

In 1971, after more than 190 failures, Tu finally got an extract that was 100 percent effective against the malaria para­sites .The extract was called qinghaosu, later renamed artemisinin.

According to a statement on the Lasker Foundation website, during the past four decades, Tu's drug has saved millions of lives. It is especially important for children in the poorest and least developed parts of the world. However, not many people knew of the scientist until she won the Lasker Award this month.

Lasker Awards are known as "America's Nobels" for the reason that in the last two decades, 28 Lasker Prize winners have gone on to receive the Nobel Prize, and 80 since 1945, according to Xinhua News Agency.

" The discovery of artemisinin is a gift to mankind from traditional Chinese medicine," Tu said when she received the a-ward. "Continuous exploration and development of traditional medicine will, without doubt, bring more medicines to the world.

A. It is unnecessary to study abroad as a scientific researcher.

B. Chinese medicine used not to be recognized in Western countries.

【解析】

试题分析：本文属于新闻报道，主要介绍了2015年诺贝尔医学奖获得者屠呦呦的个人事迹和获奖信息。

1.C 推理判断题。根据本段前三句Tu Youyou a scientist at the China Academy of Chinese.....Engineering.可知屠呦呦并没有显赫的背景，也没有读过大学。根据后一句... the medical prize of the Albert and Mary Lasker Foundation可知她获得了美国诺贝尔奖“Lasker Awards”说明她取得来了很大的成就。故C正确。

2.D 推理判断题。根据第五段最后两句和第六段Maybe, thought Tu, the effective ingredient in qinghao was destroyed by high temperatures.....effective against the malaria para­sites .The extract was called qinghaosu, later renamed artemisinin.可知屠呦呦认为高温破坏了青蒿的药用效果，她想部分降低温度提炼青蒿素。后来取得成功。说明她用创造性的方法取得成功。故D正确。

3.A 推理判断题。青蒿素对于贫穷国家的儿童很有效是因为它的原料很普遍，很容易就找到青蒿。另外价格很便宜，贫穷国家的人也承担得起。故A正确。
