非限制性定语从句中，which的指代对象需根据语法结构具体分析，主要分为以下四类情况：

一、指代主句中的名词或名词短语

which最常见的用法是直接指代主句中出现的具体名词（通常为物），在从句中充当主语或宾语‌。例如：

"The book, which I bought yesterday, is very useful."（which指代先行词"the book"）‌

"She achieved the first prize, which I never did."（which指代"the first prize"）‌

二、指代主句中的形容词

which可指代主句中形容词所描述的性质，此时从句常包含比较结构‌。例如：

"She was very kind, which her husband never was."（which指代"very kind"）‌

三、指代主句中的从句内容

当which指代主句中某个从句表达的具体内容时，需通过语义判断‌。例如：

"He said he would help you, which turned out to be false."（which指代"he would help you"这一陈述）‌

四、指代整个主句

which可指代主句整体内容，此时从句常表达结果、评价或补充说明‌。例如：

"He failed the exam, which surprised everyone."（which指代"他考试失败"这一事实）‌
