答案：[解题导语]本文是一篇记叙文。屠呦呦是中国第一个获得诺贝尔奖的女科学家，她带领她的团队发现了青蒿素，从而挽救了数百万人的生命。

1．but 解析：考查连词。空前语境：青蒿在中国是一种常见的植物；空后语境：它有治愈致命疾病——疟疾的能力。根据空处前后语境可以判断，两句为转折关系，故用转折连词but。

2．is 解析：考查时态和主谓一致。根据该句中的“who uses the plant's special power”可知，该句应用一般现在时。又因主语为Tu Youyou，故用is。

3．to receive 解析：考查动词不定式。根据该句中的“the first native Chinese person”可以判断，该句应用动词不定式作person的后置定语。

4．it 解析：考查it的用法。分析该句结构可知，动词不定式短语to fight for the health of all humans作真正的主语，it作形式主语。

5．that/which 解析：考查定语从句。分析该句结构可知，该句为定语从句，先行词为medicine，空处在从句中作主语，故用which或that引导该定语从句。

6．medicines 解析：考查名词的数。根据该句中的them可以判断，空处应用复数形式。

7．by/on/at/in 解析：考查介词。by hand意为“用手”；on hand，at hand，in hand意为“在手头”。根据语境可知这四个介词都对。

8．returned 解析：考查时态。根据下句的“Her little daughter didn't recognize her”可知，这里陈述的是过去的事情，故用一般过去时。

9．trying 解析：考查非谓语动词。spend time doing sth.为固定搭配，意为“花费时间做某事”，故用trying。

10．from 解析：考查动词短语。suffer from为固定搭配，意为“(因疾病、痛苦等)受折磨”。

Ⅳ.短文改错
