关于这个英文句子
If someone loves a flower,of which just one single blossom grows in all the
millions and millions of stars,it is enough to make him happy just to look at
the stars.He can say to himself,"Somewhere,my flower is there…" But if the
sheep eats the flower,in one moment all his stars will be darkened… And you
think that is not important!
请问 这句话的第一句 非限定定语从句中 of which指代什么 为什么要加of 呢 如果指代的是 a flower 那么 直接用限定性定语从句a flower which不就好了吗?

Answer 1

必须要加上of的,因为one single blossom是这个flower的一个部分而已,不是全部.one single blossom of the flower.
类似结构：I have a family,of which my father is the one in charge.
