请教一句话的理解
Whilespeakersmayvaryintheirownspeechacrossdialectboundaries,oftensubconsciously,theywereeasilyawareofslightdifferencesinthespeechofothers.【Aformoflinguisticprejudiceemergesinthatgroupsmayarbitrarilydefinetheirownspeechasbetterthanthoseofothers.】
括号中的句子是不是个病句?
因为:
1、【Aformoflinguisticprejudiceemergesinthatgroups】mayarbitrarilydefinetheirownspeechasbetterthanthoseofothers. 把括号中的部分理解为主语从句
2、Aformoflinguisticprejudice【emergesinthatgroups】mayarbitrarilydefinetheirownspeechasbetterthanthoseofothers.把括号中的部分理解为定语
按1、2两种方式理解,句子理解起来都不通顺.
