例8　Other models exist that are hybrids of these three, such as delayed open-access, where journals allow only subscribers to read a paper for the first six months, before making it freely available to everyone who wishes to see it.

【结构分析】主干是Other models exist，定语从句是that are hybrids of these three，修饰主语，倒装到了句子后面，后面是介词短语举例子，也就是such as delayed open-access，后面是定语从句where journals allow only subscribers to read a paper for the first six months，后面是分词状语before making it freely available to everyone who wishes to see it，修饰前面的定语从句。

【亮点回放】此句话的亮点在于分割结构的使用，动词exist的插入导致主语和定语从句分割开来，而且定语从句套上分词状语，很经典。
