Industrialization and modern methods ofinsect control have improved the standard of living around the globe while at the same time theyhave introduced some 100,000 dangerous chemical pollutants, having gone virtuallyunregulated since they were developed more than 50 years ago. (A) while at the same time they haveintroduced some 100,000 dangerous chemical pollutants, having
(A) 整个句子中的两个代词they指代对象不一致,划线部分they没有指代对象,未划线部分的they指 代的是pollutants;having gone…分词结构有作伴随状语修饰have introduced的歧义,而不是作 pollutants的定语。
prep 对A选项的解释说划线部分they 没有指代对象,可是根据之前的归纳不是说过从句中的代词首先指代主句主语,其次宾语表语么?是不是说其实解释想表达的意思是,因为这个they指代主句中的methods , 而未划线部分的they 指代pollutants, 因此根据句中相同代词指代一致性来判断A选项是错的?
ps 能不能哪位大神给下关于并列句中,从句中,代词指代的总结啊啊啊~~~~~~~~~~~~跪求~~~~~~~~~~~~~~~
