请问下句话I didn't realize后的句子是感叹句还是宾语从句,from schools in China又表示什么
I didn't realize how different schools in the UK are from schools in China until I read your article.

在读了您的文章后我才知道英国的学校和中国的学校的差异.
“realize” 后接 宾语从句
until I read your artical为状语
"A be different from B" 表A/B 间的 “不同” “区别” “差异”
句子中“how”表示程度.
仅供参考
