先分析一下句子结构.整个句子由主句和结果状语从句构成,主句是:Individuals,people best reflect the reality of their time,of the age that they lived in,其中主语是individuals (people是主语的同位语),谓语是reflect,而后面of the age that they lived in是对of their time的进一步说明,相当于the reality of the age that they lived in,最后的so she pained portraits是整个句子的状语从句.
整句译文:对她来说,个体(或即人们)最充分地反映了他们的时间亦即他们所度过的岁月,所以她那时画肖像.
