题目内容
2.Tu Youyou,who is the first female Nobel Prize winner in China,discovered a drug for malaria(疟疾),which saved millions of lives across the globe,especially in the developing world.分析 屠呦呦,中国第一位女性诺贝尔奖获得者,发现了一种治疗疟疾的药物,它挽救了全球特别是发展中国家数百万人的生命.
解答 答案:who; which
根据句意以及空缺处之前的逗号可知,本句含有两个非限定性的定语从句;一个用来修饰主语,另一个用来修饰宾语;第一个先行词是Tu Youyou,指人,在从句中作主语,故前一个空应填关系代词who;第二个先行词是a drug for malaria,指药物,在第二个从句中作主语,故后一个空应填关系代词which;故答案为:who; which
点评 做本题的关键在于应根据句意以及句子的结构特点,判断出句中的非限定性定语从句;其次应掌握关系代词在非限定性的定语从句中的用法.
