学员疑问:老师,医学真题 2018年 ,全球变暖主题,75题:正确答案B,错选 D。不明白。
老师解答: 定位原文最后一句的 “showing the researchers to gather information on a more regular basis than they would be able to with piloted aircraft”,关键在于比较级on a more regular basis than...这个细微点,因此,选项B. get more data to be required for their research更符合原文,选项D. conduct their research at a regular basis没有比较意义。
点评分析:需要依据原文,辨析选项的细微差别,识别哪个最符合原文。
