以一种前所未有的方式解构现实的欲望,突然之间可能被另一种准确具体记载花草结构和纹理的欲望所取代,而这种欲望可能被认为是科普作家所特有的.
这句的主语是A desire...might give away abruptly to the desire.一种desire可能突被被另一种desire取代

优质解答

主语：A desire to throw over reality a light that never was,其中包含一个定语从句that never was修饰light,to throw over reality a light不定式作后置定语修饰desire
谓语might give away
what we might consider a novelist-scientist宾语从句
to record exactly and concretely不定式作后置定语修饰desire
the structure and texture of a flower是record的宾语
give away to 被取代
on the part of 就...而言
