麻烦看下这句话中的that从句是个什么从句?
high quality nursery schools could be established that would support families more in terms of raising the next generation
这句话中的that would support……这个that从句是个什么从句?主语从句我觉得不是吧,宾语从句也不像,定语从句的话先行词是established吗,也不可能吧!这到底算是啥从句?
我觉得结果状语从句和分隔式定语从句好像都有道理,还是不确定,这两者还怎么区分

high quality nursery schools could be established that would support families more in terms of raising the next generation
that would support families more in terms of raising the next generation
就是定语从句.先行词是high quality nursery schools
这种定语从句叫做分隔式定语从句,也就是先行词与从句分隔开.(主要是为了句子平衡或不产生歧义)
如:
The film brought the hours back to me when I was taken good care of in that far-away village.
