Question

关于这句英语的语法
Essentially,a theory is an abstract,symbolic representation 【of what】 is conceived to be reality.
括号中of what 是什么用法,请分析下它的语法

Answer 1

这是个“主---系---表”结构.
主语：a theory
谓语：is
表语：an abstract,symbolic representation
of 不是与what一起的,of是与后面整个句子一体的,做representation的所有格,what is conceived to be reality 是个宾语从句,做of的宾语.整个of what is conceived to be reality做representation的定语.
