[求助]2001年10月语法24题

语法笔记上说SO MUCH是名词性的，但是在金山词霸上SO MUCH可以做副词、形容词、代词，其中一个例句：The ideas of the candidates are so much alike that he could see no difference between them.不是和这道题一样吗？实在找不出这道题错哪了！！

he?指代不明确->you

例句是字典上的，不是我说的那道改错题。原题是：Many dinosaurs were so much heavy that they spent most of their lives in swamps and shallow lakes where water could support them.

tell me a rule

much 只能用来修饰 不可数名词 和 比较级
