学员疑问:这道题为什么不选B?
Publishing in scientific journals is the most common and powerful means to disseminate new research findings. Visibility and credibility in the scientific world require publishing in journals that are included in global indexing databases such as those of the Institute for Scientific Information (ISI). Most scientists in developing countries remain at the periphery of this critical communication process, exacerbating the low international recognition and impact of their accomplishments.
87. According to the author, the low international recognition and the impact of scientists of developing countries are attributed to ______.
A. their reluctance to publish the ISI journals
B. their low involvement in international science activities
C. their limited publications in global indexing database
D. their poor understanding of the current scientific practices
老师解答:题干比较长,这很方便我们定位。通过are attributed to可知是问题干的结果是因为下面哪个选项的原因导致的?根据关键词定位到文章第一段第三句话Most scientists in developing countries remain at the periphery of this critical communication process。但是这句话中代词,代词this是指代前一句Visibility and credibility in the scientific world require publishing in journals that are included in global indexing databases,即发表文章需要在收录在全球索引数据库的期刊中发表。也就是说发展中国家的科学家在全球索引数据库的期刊中发文章处于边缘地带,和C项“在全球索引数据库中有限的发表文章”意思一致。因此选C.。而B项在国际科学活动中底的参与,文章未提及,只是利用low进行的干扰。
点评分析:首先需要审题,明确因果关系。其次如果定位句有代词,记得往前找,还原代词指代的内容,再看同义替换的选项。
