The more one knows about the ,the more you understand the importance of the British Navy哪里有错误

前后主语不一致，改为The more one knows about that ,the more one understands the importance of the British Navy

The more one knows about that ,the more importance of the British Navy you understand

"one knows"有错误~
你题目没打全~ 在one knows about后面应该加“England”...

the more..the more两边的主语要一样，把前面一个one knows改成you know,或者改后面的

第一个分句后没有宾语
