一个英语句子 Very much he knows about it is wrong.这句话错在哪儿啊,very mu

Very much he knows about it is wrong.
这句话错在哪儿啊,very much 的使用不对么?
答：去掉very-->Much he knows about it is wrong.
译：关于这件事,他所知道的很多是错误的.
析：Much是不定代词,可以代替“很多的不可数的东西”,可以作主语：Much is wrong.
后面的he knows about it是它的定语（从句）.省略了关系代词 that (在从句中作knows的宾语,about it 是从句中的状语.
very much是副词词组,用于修饰谓语动词的如：Thank you very much.在句子中作状语,不可作主语.
