功能注释:本句主干为The most drastic reaction has been the emergence of Sci-Hub。and thoroughly illegal为插入语,语义上与most 解释Sci-Hub。set up in 2012为过去分词短语作Sci-Hub后置定语,说明它的创立时间。which引导非限制性定语从句修饰Sci-Hub,进一步补充说明Sci-Hub的发展状况。在非限制性定语从句中published since 2015也是过去分词短语作后置定语修饰paywalled article。
句意:最为急剧的,也是完全违法的抵制是Sci-Hub的出现。Sci-Hub-它有点类似于全球性的科学论文的复印机,是在2012年创立的,现声称可以提供2015年以来发表的所有付费论文的访问权。
